This study was carried out to produce biscuits as therapeutic diets. Raw materials of tomato processed waste (TPW) were used as a source of some amino acids and elements, (phosphorus, potassium and magnesium), besides amino acids (Phenyl alanine was found to be the first limiting amino acids while lysine was the second limiting one). It was present about 30.66% fiber and 28.1% protein. The total tomato processed wastes remain un-utilized and they not only add to the disposal problem but also aggravate environmental pollution. Tomato processed wastes were irradiated at two doses (1.5 and 2.5 kGy) for preservation. Biscuits were made with supplementation of 5, 10 and 15% (TPW). All samples of biscuits were examined for chemical composition and organoleptic evaluation. Biological assay was carried out on rats fed biscuits containing 15% irradiated and non-irradiated (TPW). The weight gain, serum cholesterol and triglycerides were determined, besides the internal organs. The results obtained showed that 15% (TPW) biscuit had the highest content of lysine, isoleucine and fiber (6.36 and 24.80, respectively) and also scored a good grade. Weight gain, cholesterol and triglycerides were reduced comparable to control and there was significant changes were recorded irradiation treatment on the rats internal organs

The study was conducted to prepare supplemented biscuits which could be used as nutritive snacks for malnourished children. Biscuits were prepared by supplementing chickpea and oat in patent flour (fine flour) with different ratio (5%, 10%, 15% and 20 %). Biscuits with no supplementation were kept as control treatment. Chemical and sensory evaluation of supplemented biscuits was carried out. An increase in nutritive values have been observed with an increase in supplementation level. Proximate analysis shows that T/sub 7/ and T/sub 8/ get the highest values for protein, zinc and iron. Results of all treatments were in acceptable range regarding sensory evaluation. These results indicate that biscuits can be successfully supplemented with chickpea and oat. According to sensory evaluation, biscuits containing 20% chickpea and 15% oat were found to be the best among all treatments and could be a potential composition for preparing high energy biscuits for malnourished areas of Pakistan.

Full Text Available Characteristics of sugar snap and chocolate chip cookies, and hazelnut biscuits made from refrigerated and frozen dough were studied. Doughs were stored at 4 °C for 6 weeks and at –18 °C for 6 months, respectively. Physical characteristics of the biscuit samples such as spread, baking loss, surface colour and density were determined. Dough colour was not affected by storage time and temperatures. Biscuit characteristics did not change significantly during storage. Spread ratio was significantly lower for the biscuits baked in the gas oven than for the biscuits baked in the electric oven. Biscuit dough can be refrigerated for 6 weeks, and frozen for 6 months. Results also suggest that unique quality differences exist between the two ovens. For sugar snap cookies and hazelnut biscuits the electric oven without air circulation was better, while for chocolate chip cookies gas oven with air circulation was more suitable.

The challenges of malnutrition and urbanization in Africa demand the development of acceptable, affordable, nutritious complementary-type foods. Biscuits (i.e. cookies; a popular snack) from whole grain staples are an option. The present study aimed to relate check-all-that-applies (CATA) sensory profiles of sorghum-cowpea composite biscuits compared to economic commercial refined wheat biscuits with hedonic ratings by low income consumers. In addition, the nutritional composition and protein quality, L * a * b * colour and texture of the biscuits were determined. The CATA method is suitable for rapidly determining which attributes consumers perceive in food products and relating these to acceptability. Consumers preferred the lighter, more yellow wheat biscuits with ginger, vanilla, sweet and cinnamon flavours compared to the stronger flavours (sorghum, beany and nutty) and harder but brittle, grittier, dry and rough textured sorghum or sorghum-cowpea biscuits. However, a substantial proportion of consumers also liked the latter biscuits. The composite biscuits had higher dietary fibre content and a similar protein quality to the standards. Whole grain sorghum-cowpea biscuits could serve as acceptable value-added nutritious complementary snacks for consumers in sub-Saharan Africa. The biscuits are simple to produce for the creation of viable small enterprises. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

2014-07-23

The formation of free monochloropropane-1,2-diol (3-MCPD and 2-MCPD) and its esters (bound-MCPD) was investigated in biscuits baked with various time and temperature combinations. The effect of salt as a source of chloride on the formation of these processing contaminants was also determined. Kinetic examination of the data indicated that an increasing baking temperature led to an increase in the reaction rate constants for 3-MCPD, 2-MCPD, and bound-MCPD. The activation energies of formation of 3-MCPD and 2-MCPD were found to be 29 kJ mol(-1). Eliminating salt from the recipe decreased 3-MCPD and 2-MCPD formation rate constants in biscuits by 57.5 and 85.4%, respectively. In addition, there was no formation of bound-MCPD in biscuits during baking without salt. Therefore, lowering the thermal load or limiting the chloride concentration should be considered a means of reducing or eliminating the formation of these contaminants in biscuits. Different refined oils were also used in the recipe to test their effect on the occurrence of free MCPD and its esters in biscuits. Besides the baking process, the results also confirmed the role of refined oil in the final concentration of these contaminants in biscuits.

2016-12-01

Full Text Available The article is devoted to the research of applicability of gluten-free flours from cereal crops and from by-products of cereal crop processing - ground crumbs sifted out in a process of flake production from rice, corn and millet during the production of biscuit semi-finished products. Taking into account that viscosity is an important technological characteristic of foam-like biscuit dough, as it determines foam strength and dispersed medium stability, the influence of gluten-free flours on the structural and rheological properties of biscuit dough was studied. It is determined that the substitution of wheat flour for cereal flours leads to viscosity reduction of the dough as a consequence of absence of gluten-forming proteins in them. A comparative analysis of changes in viscous properties of biscuit dough based on flour from flakes crumb while warming it up to 60°C with dough based on cereal flours and dough based on wheat flour was held. It is shown that the presence of partially gelatinized starch granules in flour from flake crumb, as a result of technological peculiarities of their extraction, promotes greater demonstration of thickening properties already at the initial stage of baking than in cereal flours. This leads to an increase of dough viscosity and formation of desired rheological characteristics, which provide the porous structure of finished products. To provide the high quality of gluten-free biscuit semi-finished products, the recipe composition of gluten-free biscuit semi-finished product, based on flour mixture from millet flakes crumb, corn and rice flour, was optimized by using the method of mathematical design of experiments.  The porosity indicator was chosen as the criteria for the evaluation of influence of proportion of gluten-free flours on the quality of biscuit semi-finished products. The response surfaces of dependency of biscuit porosity from mass ratio of recipe components in the composite mixture were

Full Text Available Matcha green tea powder (MGTP is made with finely ground green tea leaves that are rich in phytochemicals, most particularly catechins. Shortbread biscuits were enriched with MGTP and evaluated for consumer acceptability and potential functional health properties. Baking decreased the content of total catechins by 19% compared to dough, although epimerization increased the amount of (+-gallocatechin gallate at the expense of other catechins such as (−-epigallocatechin gallate. Consumer acceptability tests using a 9-point hedonic scale showed that consumers preferred enriched biscuits with low content of MGTP (2 g of MGTP 100 g−1 of flour, and an increase of sugar content did not significantly improve the acceptability of MGTP-enriched biscuits. Overall, enrichment of biscuits with MGTP did not significantly affect the postprandial glucose or triglyceride response (area under curve compared to non-enriched biscuits consumed with water or MGTP drink. Enriching biscuits with Matcha green tea is acceptable to consumers, but may not bring significant postprandial effects.

Full Text Available Purple rice flour contains high levels of a number of antioxidant compounds; however, it has seldom been used as an ingredient in bakery products. The aim was to increase the nutritional value of biscuits by adding purple rice flour to a basic wheat flour biscuit. The substitution of purple rice flour in place of wheat flour modified the characteristics of the biscuits in terms of increasing the nutritional values. They contained high fiber, antioxidants, and antioxidant activities, while slightly changing the physical properties such as hardness and spread ratio. The study showed that the protein digestibility increased as the content of the purple rice flour was increased in the biscuit mix. The 100% purple rice flour biscuits had the lowest predicted glycemic index (pGI of all the biscuits. Sensory analysis showed that the overall acceptability of the blended flour biscuits at 25 and 50% substitution levels was slightly less than that of the control biscuits with only 9%; however, the scores were above 5 which means the panelists still liked the biscuits a lot. Overall, the inclusion of purple rice flour in biscuits mix increased crude protein content, protein digestibility, and bioactive compounds with acceptable sensory scores from consumers up to 50% substitution of purple rice.

Full Text Available Thermal conductivity of a food material is an essential physical property in mathematical modelling and computer simulation of thermal processing. Effective thermal conductivity of non-homogeneous materials, such as food matrices, can be determined experimentally or mathematically. The aim of the following research was to compare the thermal conductivity of short pastry biscuits, at different baking stages (60-160 min, measured by a line heat source thermal conductivity probe and estimated through the use of thermo-physical models. The measures were carried out on whole biscuits and on powdered biscuits compressed into cylindrical cases. Thermal conductivity of the compacted material, at different baking times (and, consequently at different moisture content, was then used to feed parallel, series, Krischer and Maxwell-Eucken models. The results showed that the application of the hot wire method for the determination of thermal conductivity is not fully feasible if applied directly to whole materials due to mechanical changes applied to the structure and the high presence of fats. The method works best if applied to the biscuit component phases separately. The best model is the Krischer one for its adaptability. In this case the value of biscuit thermal conductivity, for high baking time, varies from 0.15 to 0.19 Wm–1 K–1, while the minimum, for low baking time, varies from 0.11 to 0.12 Wm–1 K–1. These values are close to that reported in literature for similar products.

There is an increasing push by consumers for new food products that can provide health benefits. To develop these products, sometimes it is necessary to look to alternative crops, 1 of which is millet. For millet to be successfully adopted by consumers, it is necessary to identify and develop product types that are acceptable to North Americans. Biscuits and extruded snacks were produced using varying amounts of refined proso millet flour (0%, 25%, 75%, and 100%). Sensory analysis was conducted on 8 products (4 types of biscuits and 4 types of extruded snack) in 2 separate tests (1 for biscuits and 1 for snacks). Preferred Attribute Elicitation (PAE), a relatively new sensory method, was used to determine attributes affecting liking of the products. Results indicated that as the amount of millet in the biscuits and extruded snacks increased, the liking of the flavor, texture and overall liking decreased. Millet contributed to a bitter taste and bitter aftertaste, and resulted in gritty and dry food products. Further work is required to refine the products tested as well as to identify further products that can be added to the diet in order to take advantage of the health benefits that millet provides. © 2016 Institute of Food Technologists®

The present investigation has been carried out to produce high quality biscuits for treatment of some special diseases. In this study, the total tomato processing wastes were used as new source of protein in which the most predominate elements were found to be phosphorus, potassium and magnesium. Phenyl alanine was found to be the first limiting amino acid, while lysine was the second limiting amino acid. It was found to contain about 30.66% fiber and 28.1% protein. The total tomato processing wastes remain unutilized and they not only add to the disposal problem, but also aggravate environmental pollution. Tomato wastes were irradiated in two doses (1.5 and 2.5 KGy) for preservation. Biscuits were made with supplementation of 5, 10 and 15% tomato wastes. All samples of biscuits were examined for chemical composition and organoleptic evaluation. Biological assay was carried out on rats fed biscuits containing 15% irradiated and non-irradiated tomato wastes. The weight gain, serum cholesterol and triglycerides were determined. Internal organs were also followed. The results obtained showed that 15% tomato wastes biscuit had the highest content of lysine, isoleucine and fiber (6.36, 2.72 and 24.80, respectively) and also scored a good grade. Weight gain, cholesterol and triglycerides were reduced comparable to control and there was no effect of irradiation on the rats internal organs

Under-nutrition in older adults is widespread. Oral nutritional supplement beverages (ONS) are prescribed, yet consumption by older people is often insufficient. A variety of supplement formats may improve nutrient intake. This study developed protein and micro-nutrient fortified biscuits and evaluated their sensory attributes and liking by older people. Two micro-nutrient strategies were taken, to match typical ONS and to customise to the needs of older people. Oat biscuits and gluten-free biscuits developed contained over 12% protein and over 460 kcal 100 g(-1). Two small (40 g) biscuits developed to match ONS provided approximately 40% of an ONS portion of micro-nutrients and 60% of macro-nutrients; however, the portion size was considered realistic whereas the average ONS portion (200 mL) is excessive. Biscuits developed to the needs of older adults provided, on average, 18% of the reference nutrient intake of targeted micro-nutrients. Sensory characteristics were similar between biscuits with and without micro-nutrient fortification, leading to no differences in liking. Fortified oat biscuits were less liked than commercial oat biscuits, partly attributed to flavour imparted by whey protein fortification. Macro- and micro-nutrient fortification of biscuits could provide an alternative fortified snack to help alleviate malnutrition in older adults. © 2013 Society of Chemical Industry.

Acrylamide and 5-hydroxymethylfurfural formation during baking of biscuits: Part I: Effects of sugar type.

Science.gov (United States)

Nguyen, Ha T; Van der Fels-Klerx, H J Ine; Peters, Ruud J B; Van Boekel, Martinus A J S

2016-02-01

This study aimed to investigate the effects of sugar type on the reaction mechanism for formation of acrylamide and 5-hydroxymethylfurfural (HMF) during the baking of biscuits at 200°C using multiresponse modelling. Four types of biscuits were prepared: (1) with sucrose, (2) with glucose and fructose, (3) with fructose only and (4) with glucose only. Experimental data showed that HMF concentration was highest in biscuits with glucose and fructose, whereas acrylamide concentration was highest in biscuits with glucose, also having the highest asparagine concentration. Proposed mechanistic models suggested that HMF is formed via caramelisation and that acrylamide formation follows the specific amino acid route, i.e., reducing sugars react with asparagine to form the Schiff base before decarboxylation, to generate acrylamide without the Amadori rearrangement product and sugar fragmentation. Study results contribute to understanding chemical reaction pathways in real food products. Copyright © 2015 Elsevier Ltd. All rights reserved.

Fat is an important ingredient in baking products and it plays many roles in providing desirable textural properties of baking products, particularly biscuit. In this study, the effect of fat types on dough rheological properties and quality of semi-sweet biscuit (rich tea type) were investigated using various techniques. Texture profile and extensibility analysis were used to study the dough rheology, while three-point bend test and scanning electron microscopy were used to analyse the textural characteristics of final product. TPA results showed that the type of fat significantly influenced dough textural properties. Biscuit produced with higher solid fat oil showed higher breaking force but this was not significantly different when evaluated by sensory panel. Scanning electron microscopy showed that biscuit produced with palm mid-fraction had an open internal microstructure and heterogeneous air cells as compared to other samples.

A niche market in alternative foods has emerged in response to interest in a health conscientious diet. The purpose of this study was to evaluate the baking characteristics of teff to determine whether teff could produce satisfactory baked products. Cakes, cookies, biscuits and bread were made in triplicate from composites of wheat flour with 0, 10, 20, 30, 40 and 100% teff flour. Objective tests on size, shape, color and texture were used to evaluate the quality of the baked products. Increases in percent teff resulted in decreases in bread and cake volume (p > 0.05). The fracture strength of the cookies were not significantly different (p > 0.05) but spread was significantly greater for cookies made with 40% and 100% teff flour (p ≤ 0.05). There was also significant difference (p ≤ 0.05) in biscuit height and color among teff treatments. Overall, this study showed that teff flour is best suited for use in cookies and biscuits.

2017-09-01

This study investigated acrylamide and 5-hydroxymethylfurfural (HMF) formation during biscuit baking. Four types of wheat flour with different molar ratios of total fructose and glucose to asparagine were investigated. Nevertheless, the molar ratio in all four biscuit doughs exceeded one after proofing due to enzyme action. Data obtained after baking were used to develop a mechanistic model, based on the asparagine-related pathway, for acrylamide and HMF formation in the four baked biscuit types. Asparagine reacted with fructose to form a Schiff base before decarboxylation to produce acrylamide without Amadori rearrangement product and sugar fragmentation. Fructose contributed considerably to acrylamide formation and to HMF formation via caramelization in all four biscuit types. No clear correlation was found between acrylamide and HMF in baked biscuits, nor between asparagine and the sum of glucose and fructose concentrations in the wheat flour.

The technology of food irradiation is seen by the industry as a means of ensuring food safety, since it exposes foods to ionizing radiation that kills insects, moulds and bacteria. The need to eliminate bacterial pathogens from read-to-eat food products must always be balanced with the maintenance of product quality. In addition to determining the effective ionizing radiation doses required for pathogen elimination the effects of irradiation on product chemistry, nutritional value and quality must also been determined. Vitamin E ({alpha}-tocopherol) is one of the most potent natural lipophilic antioxidants commonly present in the human diet. As it is considered a free radical scavenger there is a growing concern that irradiation might reduce the vitamin E content of food products prepared with ingredients rich in any of the dietary source of the vitamin. This work describes the effects of ionizing radiation on the vitamin E content of some biscuits commercially found in the market. Three lots of biscuits were used. Irradiation was performed in a {sup 60}Co Gammacell 220 source, dose rate of about 3.5 kGy/h at doses of 1 kGy and 3 kGy. For vitamin E determination samples were saponified with ethanolic potassium hydroxide in the presence of pyrogallol, and the tocopherols were extracted with petroleum ether. The absorbance was measured at 520 nm. From the obtained results it is possible to conclude that there was a notorious stability of the vitamin content of the biscuits submitted to gamma-irradiation at the assayed doses. (author)

Content of 5-hydroxymethyl-2-furfural in biscuits for kids

Directory of Open Access Journals (Sweden)

Švecová Blanka

2017-10-01

Full Text Available 5-hydroxymethyl-2-furfural (5-HMF is a thermal decomposition product of saccharides. There are two main ways for the formation of 5-HMF. First, 5-HMF is forming during Maillard reaction and second, during thermic dehydration of saccharides under acid conditions. Significant parameters of 5-HMF formation are temperature, time, pH, water activity, type of saccharide and amino acids. It is suspected that 5-HMF has genotoxic, mutagenic and carcinogenic potential. This chemical can be found in many food sources, e.g. honey, dried fruits, fruit juice and concentrates, alcoholic beverages, bakery products, roasted nuts and seeds, brown sugar, and milk. The present study aimed to determine the amount of 5-HMF in children's biscuits. The examined samples were divided into three groups. The first group of biscuits claimed availability for children older than six months, the second for children older than one year. The third group did not give a determined age range.

Ammonia caramels are the most common antioxidant colour agent used in bakery formulations, although their high sugars content. An alternative could be coffee melanoidins, which are brown coloured compounds with antioxidant properties, readily available from instant coffee. However, high caffeine content is limiting its direct application. To evaluate the possibility of obtaining coloured melanoidin-rich, sugars- and caffeine-poor fractions from instant coffee, in this work, simple procedures based on their ethanol insolubility (fraction EtPp) or retention by ultrafiltration (fraction HWSn) were exploited. Melanoidins incorporation into biscuits formulation (amounts of 1, 5 and 10% w/w related to flour content) resulted in acceptable coloured products with higher antioxidant activity. The biscuits supplemented with 1% EtPp or HWSn had a low caffeine content. The caffeine of one espresso coffee was equivalent to 130 biscuits containing EtPp and 31 biscuits containing HWSn. Besides, both fractions did not promote extra formation of acrylamide or 5-hydroxymethylfurfural during baking. Copyright © 2017 Elsevier Ltd. All rights reserved.

Matić, Tomislav; Aleksi, Ivan; Hocenski, Željko; Kraus, Dieter

2018-05-01

In this paper we propose a novel real-time Biscuit Tile Segmentation (BTS) method for images from ceramic tile production line. BTS method is based on signal change detection and contour tracing with a main goal of separating tile pixels from background in images captured on the production line. Usually, human operators are visually inspecting and classifying produced ceramic tiles. Computer vision and image processing techniques can automate visual inspection process if they fulfill real-time requirements. Important step in this process is a real-time tile pixels segmentation. BTS method is implemented for parallel execution on a GPU device to satisfy the real-time constraints of tile production line. BTS method outperforms 2D threshold-based methods, 1D edge detection methods and contour-based methods. Proposed BTS method is in use in the biscuit tile production line. Copyright © 2018 ISA.

Aditi, Mahapatra; Shashirekha, M N; Sudha, M L

2017-06-01

Expanding the range of bakery products in terms of producing supplemented or dietetic products has been an increasingly important trend in contemporary baking. Value added products, especially products rich in fiber and phytochemicals are getting popular. Among the dry fruits used for filling, Figs were rich in ash and protein and Dates were rich in dietary fiber. Gallic acid was the dominant free phenolic acid in Fig whereas chlorogenic acid and procatechuic acid were dominant in Dates in the bound form. Farinograph water absorption, dough development time, maximum pressure (P), and extensibility (L) decreased on increase in the replacement of wheat flour with chiku powder from 0 to 30%. The dry fruit fillings in the pH range of 3.3-3.5 with 75-80°Bx showed better bake stability with respect to spreadability and breaking strength. Biscuits topped with higher °Bx fillings had higher breaking strength values even during storage. Among the gelling agents used, addition of sodium alginate stabilized and further improved the bake stability of the fillings. The chiku incorporated biscuits sandwiched with fruit filling were rich in dietary fiber. Also significant amounts of gallic acid and chlorogenic acid in free and bound form were present in the biscuit. Bakery products can act as a vehicle for supplementation of vitamins, minerals, protein, dietary fiber, and so on, to prevent nutritive deficiencies. Among the bakery products, biscuits are shelf stable and have better consumer acceptability by all age groups. To incorporate fruits which are rich in many bioactive principles, and to add on to variety, fruit sandwiched biscuits with fruit powder in the casing too. Fillings mainly from dry fruits were prepared at varying degree brix and with different gelling agents. Biscuit sheets containing chiku powder in the formulation was topped with the fillings and looked for the bake stability with respect to texture and spreadability.

The influence of choice of flavour solvent, propylene glycol (PG) or triacetin (TA), was investigated during accelerated shelf life (ASL) testing of shortcake biscuits. Specifically, the differential effect on the stability of added vanillin, the natural baked marker compound 5-(hydroxymethyl)furfural (HMF), specific markers of oxidative rancidity (2,4-decadienal, 2,4-heptadienal), and the structural parameters of hardness and fracturability. Significantly more HMF was formed during baking of biscuits prepared with TA; these biscuits were also more stable to oxidative degradation and loss of vanillin during ageing than biscuits prepared with PG. Fresh TA biscuits were significantly more brittle than fresh PG biscuits. There was no impact of solvent choice on hardness. Sensory evaluation of hardness, vanilla flavour and oily off-note was tested during ASL testing. There was no significant impact of storage on sensory ratings for either the PG or TA biscuits.

Food fortification is one of the most effective strategies for increasing iron intake in the population. A simple blind trial was conducted to compare the effect of 2 forms of iron fortification and assess the changes in hemoglobin and iron status indices among preschool children from rural communities. Hemoglobin was evaluated in 47 children aged 3-6 years old. For 72 days (10-week period), children ate Nito biscuits. Thirteen pupils with elevated hemoglobin levels were assigned to the biscuit control group, and pupils with hemoglobin equal to 13.5 mg/dL or less were randomly allocated to consume fortified biscuits with a heme iron concentrate (n = 15) or iron sulfate (n = 19). Changes in hemoglobin, plasma ferritin, and other hematological indices were evaluated with analysis of variance (ANOVA) for repeated measurements. Except mean corpuscular hemoglobin concentrations (+1.27 ± 2.25 g/dL), hematological indices increased significantly across the study: Mean corpuscular volume (+2.2 ± 1.0 f/dL), red blood cells (+0.30 ± 0.37 M/μL), mean corpuscular hemoglobin (+1.8 ± 1.74 pg), hemoglobin (+1.68 ± 0.91 g/dL), hematocrit (+3.43% ± 3.03%), and plasma ferritin (+18.38 ± 22.1 μg/L) were all p effect of the iron-fortified chocolate biscuits in the hemoglobin levels was higher than the control group (+1.1 ± 0.2 g/dL) but no difference was found between consumers of fortified biscuits with heme iron concentrate or iron sulfate (+1.9 ± 0.2 g/dL and +2.0 ± 0.2 g/dL, respectively). Heme iron concentrate and iron sulfate were equally effective in increasing Hb levels and hematological indices. Processed foods were shown to be an effective, valuable, and admissible intervention to prevent anemia in preschool children.

Ten healthy participants (4 men and 6 women, aged 28+/-2.6 years, body mass index [BMI], 24.3+/-0.8 kg/m(2)) and 9 participants with diabetes mellitus type 2 (3 men and 6 women, aged 68+/-3.8 years, BMI 28.8+/-1.2 kg/m(2)) on four separate occasions took either 50 g available carbohydrates as control biscuits, biscuits with 10 g of highly viscous fiber blend, white bread with 12 g of margarine, or white bread alone. Postprandial blood glucose response, glycemic index (GI), and palatability were determined. Mean (95% confidence interval) GI values of the viscous fiber blend biscuits were 26 (16-36) and 37 (27-47) GI units for healthy participants and participants with diabetes mellitus, respectively. These values were significantly lower than those of white bread, white bread with 12 g of margarine, and control biscuits (Phealthy participants (GI 100, 108 [57-159], and 101 [44-158], respectively) and participants with diabetes mellitus (GI 100, 103 [79-127], and 94 [78-110], respectively). Viscous fiber blend significantly reduced the glycemic index by 74% (7.4 GI units/g of fiber) in healthy participants and by 63% (6.3 GI units/g of fiber) in participants with diabetes. The GI did not differ between control meals in both healthy participants and participants with diabetes. There were no significant differences in palatability among the types of meals, although participants with diabetes found the viscous fiber blend biscuits more palatable (P=0.002, t test). Viscous fiber blend is a very potent and palatable soluble fiber addition to a starchy snack, which is able to reduce the glycemic response to a similar extent in both healthy participants and individuals with diabetes mellitus. Biscuits with low GI, and possibly other viscous fiber blend fortified starchy

In the present study, 100 commercial breads and biscuits were investigated for the occurrence of deoxynivalenol (DON) and its acetylated derivatives 3-acetyldeoxynivalenol (3-Ac-DON) and 15-acetyldeoxynivalenol (15-Ac-DON). The target mycotoxins were determined by isotope dilution ultrahigh performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). DON was determined in 95% of the test samples with a mean value of 153.3 µg/kg. Compared with DON, 3-Ac-DON and 15-Ac-DON were far less frequently detected, with mean values of 1.14 and 0.37 µg/kg, respectively. The estimated daily intakes of the sum of DON and its derivatives in breads and biscuits were 0.0059 and 0.0313 µg/kg bw/day, respectively, which was within the group provisional tolerable daily intake of 1.0 µg/kg bw/day set by the Joint FAO/WHO Expert Committee on Food Additives. In the future, systematic monitoring programmes of DON and its derivatives in relevant foodstuffs are still necessary for food safety and human health.

Biscuits are an important type of food, widely consumed by babies in Iraq and other countries. This work uses gamma spectroscopy to measure the natural radioactivity due to long-lived gamma emitters in children's biscuits; it also estimates radiation hazard indices, that is, the radium equivalent activity, the representative of gamma level index, the internal hazard index, and the annual effective dose in children. Ten samples were collected from the Iraqi market from different countries of origin. The average specific activities for (226)Ra, (232)Th, and (40)K were 9.390, 3.1213, and 214.969 Bq/kg, respectively, but the average of the radium equivalent activity and the internal hazard index were 33.101 Bq/kg and 0.107, respectively. The total average annual effective dose from consumption by adults, children, and infants is estimated to be 0.655, 1.009, and 0.875 mSv, respectively. The values found for specific activity, radiation hazard indices, and annual effective dose in all samples in this study were lower than worldwide median values for all groups; therefore, these values are found to be safe.

In the wild, western lowland gorillas consume a diet high in fiber and low in caloric density. In contrast, many gorillas in zoos consume a diet that is high-calorie and low in fiber. Some items commonly used in captive gorilla diets contain high levels of starch and sugars, which are minimal in the natural diet of gorillas. There is a growing concern that captive gorillas may qualify as obese. Furthermore, the leading cause of death for adult male gorillas in zoos is heart disease. In humans, a diet that is high in simple carbohydrates is associated with both obesity and the incidence of heart disease. In response to these issues, we implemented a biscuit-free diet (free of biscuits and low in fruit) and measured serum biomarkers of obesity and insulin resistance pre- and post-diet change at three institutions: North Carolina Zoological Garden, Cleveland Metroparks Zoo, and Columbus Zoo and Aquarium. We also added a resistant starch supplement to gorilla diets at two of the above institutions. We anticipated that these diet changes would positively affect biomarkers of obesity and insulin resistance. Both diet manipulations led to a reduction in insulin. Resistant starch also decreased overall serum cholesterol levels. Future research will examine these health changes in a greater number of individuals to determine if the results remain consistent with these preliminary findings. © 2014 Wiley Periodicals, Inc.

Full Text Available ABSTRACT The increased demand for differentiated and health-oriented food has driven the development of bakery products with specific nutritional and sensory characteristics. The aim of this study was to compare four different biscuits: two commercial (sugar-free and gluten-free and two experimental formulations (standard and source of extra fiber. The cookie with added fiber had passion fruit albedo and pumpkin peel added to its formulation, as well as reduced wheat flour content compared with the standard formulation. These alterations aimed to achieve both nutritional and economic benefits. The Free Choice Profiling methodology was used, and the data were subjected to Generalized Procrustes Analysis. The analysis was performed separately by attribute classes (appearance, aroma, flavor and texture. The percentage of variance explained in the first dimension was 87.6% for texture, and the sum of the first two dimensions was greater than 90% for all four attributes. Both experimental formulations were characterized as having a yellowish color, flattened appearance, passion fruit aroma, natural aroma, passion fruit flavor, passion fruit residual flavor, soft texture and compact texture. Therefore, the addition of byproducts in the standard formulation did not qualitatively change the characteristic attributes. The products were also evaluated on a 9-point hedonic scale, and the data were statistically evaluated by analysis of variance (ANOVA. When compared by affective analysis, the formulation with added fiber and the commercial biscuits showed no significant difference regarding flavor and intent to purchase. Thus, the cookie developed herein has promising market potential, and it presents additional benefits due to its economic and nutritional appeal.

In the wild, western lowland gorillas travel long distances while foraging and consume a diet high in fiber and low in caloric density. In contrast, gorillas in zoos typically consume a diet that is low in fiber and calorically dense. Some items commonly used in captive gorilla diets contain high levels of starch and sugars, which are present at low levels in the natural diet of gorillas. Diet items high in simple carbohydrates are associated with obesity and heart disease in humans. Typical captive gorilla diets may also encourage undesirable behaviors. In response to these issues, we tested the behavioral impact of a diet that was biscuit-free, had low caloric density, and which was higher in volume at five institutions. We hypothesized that this diet change would reduce abnormal behaviors such as regurgitation and reingestion (R/R), decrease time spent inactive, and increase time spent feeding. The biscuit-free diet significantly reduced (and in the case of one zoo eliminated) R/R and may have reduced hair-plucking behavior. However, an increase in coprophagy was observed in many individuals following the diet change. The experimental diet caused a general increase in time the gorillas spent feeding, but this increase did not occur across all institutions and varied by individual. Interestingly, the overall time gorillas spent inactive actually increased with this diet change. Future research will examine these behavioral changes in a greater number of individuals to determine if the results remain consistent with these preliminary findings. Additionally, future research will examine the physiological impact of this diet change. © 2014 Wiley Periodicals, Inc.

Cashew apple and guava residues from fruit juice industry were prepared as dehydrated fruit powders and used at different levels of wheat flour substitution for cookies formulations. The effects of guava and cashew apple fruit powders supplementation on physicochemical and sensorial characteristics of the cookies were evaluated. The pH, fibre and protein content were significantly affected. Biscuits with 15 g and 20 g/100g cashew apple and guava fruit powders showed the highest scores for sensorial attributes, respectively. The supplementation seems to be suited for wheat flour substitution and it is possible to obtain cookies with value-added food ingredient within the standards.

Compares infants and toddlers with intellectual and developmental conditions in regard to the presence of challenging behaviour. Parents and caregivers to 140 children ranging from 17-35 months with five different conditions (Down syndrome (n = 23), developmental delay (n = 18), prematurity (n = 56), Cerebral Palsy (n = 15) and Seizure disorder (n = 28)) were administered the BISCUIT-Part 3. An ANOVA on overall scores and a MANOVA on the sub-scale scores were conducted to determine if groups differed significantly. Results found no significant differences on total scores or differences on the sub-scales of the BISCUIT-Part 3: Aggressive/Destructive, Stereotypic and Self-Injurious. Some trends in individual item endorsement were found. It is possible that differences among individuals with these disorders are not apparent until later in life. These results emphasize the importance of monitoring challenging behaviours in all at-risk infants and toddlers to ensure that early interventions to treat these challenging behaviours are possible.

The aim of this research was to determine the effect of composition (dietary fiber = DF, fat = F, and gluten = G) and baking time on the target microstructural parameters that were observed using images of potato and wheat starch biscuits. Microstructures were studied Scanning Electron Microscope (SEM). Non-enzymatic browning (NEB) was assessed using color image analysis. Texture and moisture analysis was performed to have a better understanding of the baking process. Analysis of images revealed that the starch granules retained their native form at the end of baking, suggesting their in complete gelatinization. Granules size was similar at several different baking times, with an average equivalent diameter of 9 and 27 µm for wheat and potato starch, respectively. However, samples with different levels of DF and G increased circularity during baking to more than 30%, and also increasing hardness. NEB developed during baking, with the maximum increase observed between 13 and 19 min. This was reflected in decreased luminosity (L*) values due to a decrease in moisture levels. After 19 min, luminosity did not vary significantly. The ingredients that are used, as well as their quantities, can affect sample L* values. Therefore, choosing the correct ingredients and quantities can lead to different microstructures in the biscuits, with varying amounts of NEB products.

While investigations using covert food manipulations tend to suggest that individuals are poor at adjusting for previous energy intake, in the real world adults rarely consume foods of which they are ill-informed. This study investigated the impact in fully complicit consumers of consuming commercially available dark chocolate, milk chocolate, sweet biscuits and fruit bars on subsequent appetite. Using a repeated measures design, participants received four small portions (4 × 10-11 g) of either dark chocolate, milk chocolate, sweet biscuits, fruit bars or no food throughout five separate study days (counterbalanced in order), and test meal intake, hunger, liking and acceptability were measured. Participants consumed significantly less at lunch following dark chocolate, milk chocolate and sweet biscuits compared to no food (smallest t(19) = 2.47, p = 0.02), demonstrating very good energy compensation (269-334%). No effects were found for fruit bars (t(19) = 1.76, p = 0.09), in evening meal intakes (F(4,72) = 0.62, p = 0.65) or in total intake (lunch + evening meal + food portions) (F(4,72) = 0.40, p = 0.69). No differences between conditions were found in measures of hunger (largest F(4,76) = 1.26, p = 0.29), but fruit bars were significantly less familiar than all other foods (smallest t(19) = 3.14, p = 0.01). These findings demonstrate good compensation over the short term for small portions of familiar foods in complicit consumers. Findings are most plausibly explained as a result of participant awareness and cognitions, although the nature of these cognitions cannot be discerned from this study. These findings however, also suggest that covert manipulations may have limited transfer to real world scenarios. Copyright © 2014 Elsevier Ltd. All rights reserved.

The use of Fagopyrum tataricum gaertn. whole flour to confer preventive contents of rutin to some traditional tuscany biscuits

Full Text Available To meet the growing interest for new foods that may be regarded as functional aliments, of particular interest appears the utilization of the grain of Fagopyrum tataricum. The high content of rutin available in the grain and whole flour of this species, in fact, offers the opportunity to introduce in the food recipes effective amounts of this bioactive compound. Rutin is credited with a growing multiplicity of health beneficial properties that can be reasonablysecured through the preventive nutrition approach. In this respect, the daily dose of rutin suggested by most dietary supplement preparations is around 50 mg/day. The use of F. tataricum whole flour, where the rutin content usually ranges between 1000 up to 2000 mg/100 g dry weight, allows to reach such an amount with a low percentage introduction of this ingredient in the original recipe. Higher contents of rutin are found in the herb of cultivated species of buckwheat (F. tataricum and F. esculentum. However, the handling of this material may not be as simple as that of the grain made into whole flour. Preliminary results would indicate that an intake of 50 mg of rutin with a single meal (breakfast in this case can be feasible by adding tartary buckwheat whole flour to some traditional Tuscany biscuits without impairing texture, taste and acceptability.In spite of the presence of rutin degrading enzymes, known to be present in tartary buckwheat grain, it would appear that just a negligible degradation of rutin to quercetin occurs during the phase of dough preparation and backing process so that most of the rutin present in the whole flour can be recovered in the biscuits.

Full Text Available Objective: To determine if meat or soy protein dietary supplementation will enhance the neurocognitive performance of HIV-affected children at-risk of malnutrition and food insecurity. Methods: A randomized, double-blind, controlled intervention trial evaluated the effect of nutritional supplementation on the neurocognitive outcomes of 49 HIV-affected school-age children in western Kenya. The intervention consisted in providing the mother, target child, and siblings with one of three isocaloric biscuit-type supplements – soy, wheat, or beef – on 5 days per week for 18 months. Neurocognitive outcomes of the target children were assessed by a battery of eight measures and followed up longitudinally for up to 24 months. Results: Mixed effects modeling demonstrated significant differences in the rates of increase over time among all three groups (F test degrees of freedom of 2, P<0.05 for Raven’s progressive matrices performance, but not for verbal meaning, arithmetic, digit span backward, forward, and total, embedded figure test, and Beery visual–motor integration scores. Conclusion: HIV-affected school-age children provided with soy protein supplementation showed greater improvement in nonverbal cognitive (fluid intelligence performance compared with peers who received isocaloric beef or wheat biscuits. Soy nutrients may have an enhancing effect on neurocognitive skills in HIV-affected school-age children.

Indonesia is a natural disaster-prone country. Food availability appears as the post-disaster main problem. Emergency food is an effort to overcome it. An ideal emergency food is expected to have a complete nutritional composition. Fulfilling macronutrient needs, proso millet flour and snakehead fish-tempeh flour koya were being used in this research. The objective of this research was to determine the formulation of emergency food in biscuit form made from proso millet flour and snakehead fish-tempeh flour koya based on its sensory, chemical and physical properties. This research was using a completely randomized design with one factor affecting. The variations of proso millet flour and snakehead fish-tempeh flour koya composition were 100:0 ; 80:20 ; 60:40 ; and 40:60. All treatments were carried out sensory evaluation using hedonic test, proximate analysis, calories analysis using bomb calorimetry methods. and physical analysis using texture profile analyzer. The compensatory model was used to determine the best formula based on all parameters. The result indicated that the best biscuit formula had compositions of proso millet flour 80% and snakehead fish-tempeh flour koya 20%. It had a brownish color, not-strong-fishy aroma, a strong-enough bitter aftertaste and crunchy texture. Chemical analysis showed that its moisture, ash, protein, fat, carbohydrate and total calories content were 1,146%; 4,827%; 12,536%; 26,325%; 56,312% and 5,033 kcal/gram, respectively. The physical analysis shows that its hardness and fracturability values were 8,037 N and 2,403 N, respectively.

In this research, an ultrasonic-assisted extraction followed by 2-naphthalenthiol derivatization and dispersive liquid-liquid microextraction of acrylamide (AA) was developed as simple and sensitive sample preparation method for AA in bread and biscuit samples using high performance liquid chromatography. Influence of derivatization and microextraction parameters were evaluated and optimized. Results showed that the derivatization of AA leads to improve its hydrophobicity and chromatographic behavior. Under optimum conditions of derivatization and microextraction, the method yielded a linear calibration curve ranging from 10 to 1000 μg L -1 with a determination coefficient (R 2 ) of 0.9987. Limit of detection (LOD) and limit of quantification (LOQ) were 3.0 and 9.0 μg L -1 , respectively. Intra-day (n = 6) and inter-day (n = 3) precisions based on relative standard deviation percent (RSD%) for extraction and determination of AA at 50 and 500 μg L -1 levels were less than 9.0%. Finally, the performance of proposed method was investigated for determination of AA in some bread and biscuit samples, and satisfactory results were obtained (relative recovery ≥ 90%).

To examine whether level of symptoms of co-morbid psychopathology exacerbated challenging behaviours in young children with autism spectrum disorders (ASD). Using the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT)-Part 2 which measures co-morbid symptoms and the BISCUIT- Part 3 which examines challenging behaviours, 362 infants and toddlers with ASD were evaluated. Findings showed that participants scoring high on symptoms of Avoidance and Tantrum/Conduct problems had greater rates of aggressive/destructive behaviours, self-injurious behaviours (SIB) and stereotypies compared to those with low scores. Participants with high levels of Inattention/Impulsivity or Eat/Sleep concerns, compared to those with low levels, demonstrated greater aggressive/destructive behaviour and stereotypies. For symptoms of Anxiety/Repetitive Behaviours, participants with high scores displayed greater levels of stereotypies. Symptoms of co-morbid psychopathology are present at a very early age for children with ASD and elevated levels of these symptoms may exacerbate challenging behaviours.

Digest of CFB presented a significantly ( p < 0.05) lower amount of sugar (68.6 mg/g) and a higher antioxidant capacity (15.1 mg chlorogenic acid eq./g) than that of a sucrose-containing biscuit (SCB). The CFB significantly reduced ( p < 0.05) α-glucosidase activity (IC50 = 3.3 mg/mL) compared to the SCB (IC50 = 6.2 mg/mL). Serotonin and glucagon-like peptide-1 (GLP-1) release by differentiated Caco-2 and HuTu-80 cells, respectively, was stimulated by the CFB (355% at a concentration of 0.5 mg/mL and 278% at a concentration of 0.05 mg/mL) to the same order of magnitude as those of the SCB. To summarize, the CFB was demonstrated to reduce monosaccharide bioaccessibility, to inhibit a diabetes-related digestive enzyme, and to improve the release of satiety hormones.

Food packages were objectively assessed to explore differences in nutrition labelling, selected promotional marketing techniques and health and nutrition claims between countries, in comparison to national regulations. Cross-sectional. Chip and sweet biscuit packages were collected from sixteen countries at different levels of economic development in the EPOCH (Environmental Profile of a Community's Health) study between 2008 and 2010. Seven hundred and thirty-seven food packages were systematically evaluated for nutrition labelling, selected promotional marketing techniques relevant to nutrition and health, and health and nutrition claims. We compared pack labelling in countries with labelling regulations, with voluntary regulations and no regulations. Overall 86 % of the packages had nutrition labels, 30 % had health or nutrition claims and 87 % displayed selected marketing techniques. On average, each package displayed two marketing techniques and one health or nutrition claim. In countries with mandatory nutrition labelling a greater proportion of packages displayed nutrition labels, had more of the seven required nutrients present, more total nutrients listed and higher readability compared with those with voluntary or no regulations. Countries with no health or nutrition claim regulations had fewer claims per package compared with countries with regulations. Nutrition label regulations were associated with increased prevalence and quality of nutrition labels. Health and nutrition claim regulations were unexpectedly associated with increased use of claims, suggesting that current regulations may not have the desired effect of protecting consumers. Of concern, lack of regulation was associated with increased promotional marketing techniques directed at children and misleadingly promoting broad concepts of health.

Full Text Available ABSTRACT In situation when the disaster occurres, people can be panic and can not manage appropriate food for the whole family. Therefore, it is required food supply from the authority to fulfill the nutrition need during emergency. For infants, there were milk and food products available in the market that can be given in such situation. However, for children and adults, there are no emergency food available in the market. Some post-disaster surveys indicates that food aid distributed during emergency situation only provides energy source rather than a complete nutrition. Furthermore, these foods still require processing before consumption. The aim of the study is to develop formulated ready-to-eat foods for children and adults that have a dense calories and protein that can be given in disaster-related emergency situation. The foods are produced in solid form, and has good acceptance by both panelist in laboratory and people in the field. In the early stages of research, six formulas in solid form are developed, three have savory taste and three are sweet. One formula that the most preferred by the panelist in the laboratory are chosen. The best formula is then given to field panelists in area of disaster to know their preference. Formula made from soy and sesame with sweet taste has the highest value compared with other types of formulas, and significantly different by Duncan's test from all formulas. In flavor and aroma attributes, this formula is not significantly different from others, however in crispiness; this formula has the best acceptance. The biscuits has energy 2.100 kcal per portion that 11.5 percent of the energy is from protein, 44.4 percent is from fat and the remaining 44 percent is from carbohydrates.

In this study, acrylamide exposure from selected cereal-based baby food samples was investigated among toddlers aged 1-3 years in Turkey. The study contained three steps. The first step was collecting food consumption data and toddlers' physical properties, such as gender, age and body weight, using a questionnaire given to parents by a trained interviewer between January and March 2012. The second step was determining the acrylamide levels in food samples that were reported on by the parents in the questionnaire, using a gas chromatography-mass spectrometry (GC-MS) method. The last step was combining the determined acrylamide levels in selected food samples with individual food consumption and body weight data using a deterministic approach to estimate the acrylamide exposure levels. The mean acrylamide levels of baby biscuits, breads, baby bread-rusks, crackers, biscuits, breakfast cereals and powdered cereal-based baby foods were 153, 225, 121, 604, 495, 290 and 36 μg/kg, respectively. The minimum, mean and maximum acrylamide exposures were estimated to be 0.06, 1.43 and 6.41 μg/kg BW per day, respectively. The foods that contributed to acrylamide exposure were aligned from high to low as bread, crackers, biscuits, baby biscuits, powdered cereal-based baby foods, baby bread-rusks and breakfast cereals.

Full Text Available Abstract Background The modular approach to analysis of genetically modified organisms (GMOs relies on the independence of the modules combined (i.e. DNA extraction and GM quantification. The validity of this assumption has to be proved on the basis of specific performance criteria. Results An experiment was conducted using, as a reference, the validated quantitative real-time polymerase chain reaction (PCR module for detection of glyphosate-tolerant Roundup Ready® GM soybean (RRS. Different DNA extraction modules (CTAB, Wizard and Dellaporta, were used to extract DNA from different food/feed matrices (feed, biscuit and certified reference material [CRM 1%] containing the target of the real-time PCR module used for validation. Purity and structural integrity (absence of inhibition were used as basic criteria that a DNA extraction module must satisfy in order to provide suitable template DNA for quantitative real-time (RT PCR-based GMO analysis. When performance criteria were applied (removal of non-compliant DNA extracts, the independence of GMO quantification from the extraction method and matrix was statistically proved, except in the case of Wizard applied to biscuit. A fuzzy logic-based procedure also confirmed the relatively poor performance of the Wizard/biscuit combination. Conclusions For RRS, this study recognises that modularity can be generally accepted, with the limitation of avoiding combining highly processed material (i.e. biscuit with a magnetic-beads system (i.e. Wizard.

The aim of this work was to develop a shelf-life prediction model of lipid-containing bakery products. To this purpose (i) the temperature dependence of the oxidation rate of bakery products was modeled, taking into account the changes in lipid physical state; (ii) the acceptance limits were assessed by sensory analysis; and (iii) the relationship between chemical oxidation index and acceptance limit was evaluated. Results highlight that the peroxide number, the changes of which are linearly related to consumer acceptability, is a representative index of the quality depletion of biscuits during their shelf life. In addition, the evolution of peroxides can be predicted by a modified Arrhenius equation accounting for the changes in the physical state of biscuit fat. Knowledge of the relationship between peroxides and sensory acceptability together with the temperature dependence of peroxide formation allows a mathematical model to be set up to simply and quickly calculate the shelf life of biscuits.

The present research aimed to evaluate the use of spent coffee grounds (SCG) from instant coffee as a food ingredient and its application in bakery products. Data on physicochemical characterization, thermal stability and food safety of SCG were acquired. Evaluation of feasibility as dietary fibre was also determined. Results showed SCG are natural source of antioxidant insoluble fibre, essential amino acids, low glycaemic sugars, resistant to thermal food processing and digestion process, and totally safe. In the present work, SCG were incorporated in biscuit formulations for the first time. Low-calorie sweeteners and oligofructose were also included in the food formulations. Nutritional quality, chemical (acrylamide, hydroxymethylfurfural and advanced glycation end products) and microbiological safety and sensory tests of the biscuits were carried out. Innovative biscuits were obtained according to consumers' preferences with high nutritional and sensorial quality and potential to reduce the risk of chronic diseases such as obesity and diabetes.

Full Text Available BACKGROUND: In 2010, an acute illness outbreak was reported in school students eating high-energy biscuits supplied by the school feeding programme in northwest Bangladesh. We investigated this outbreak to describe the illness in terms of person, place and time, develop the timeline of events, and determine the cause and community perceptions regarding the outbreak. METHODS: We defined case-patients as students from affected schools reporting any two symptoms including abdominal pain, heartburn, bitter taste, and headache after eating biscuits on the day of illness. We conducted in-depth interviews and group discussions with students, teachers, parents and community members to explore symptoms, exposures, and community perceptions. We conducted a questionnaire survey among case-patients to determine the symptoms and ascertain food items eaten 12 hours before illness onset, and microbiological and environmental investigations. RESULTS: Among 142 students seeking hospital care, 44 students from four schools qualified as case-patients. Of these, we surveyed 30 who had a mean age of 9 years; 70% (21/30 were females. Predominant symptoms included abdominal pain (93%, heartburn (90%, and bitter taste (57%. All students recovered within a few hours. No pathogenic Vibrio cholerae, Shigella or Salmonella spp. were isolated from collected stool samples. We found no rancid biscuits in schools and storage sites. The female index case perceived the unusually darker packet label as a "devil's deed" that made the biscuits poisonous. Many students, parents and community members reported concerns about rumors of students dying from biscuit poisoning. CONCLUSIONS: Rapid onset, followed by rapid recovery of symptoms; female preponderance; inconsistent physical, microbiological and environmental findings suggested mass sociogenic illness rather than a foodborne or toxic cause. Rumours of student deaths heightening community anxiety apparently propagated this

There are estimates of oral aluminum (Al) bioavailability from drinking water, but little information on Al bioavailability from foods. Foods contribute approximately 95% and drinking water 1-2% of the typical human's daily Al intake. The objectives were to estimate oral Al bioavailability from a representative food containing the food additive acidic sodium aluminum phosphate (acidic SALP), a leavening agent in baked goods. Rats were acclimated to a special diet that resulted in no stomach contents 14 h after its withdrawal. They were trained to rapidly consume a biscuit containing 1.5% acidic SALP. Oral Al bioavailability was then determined from a biscuit containing 1% or 2% acidic SALP, synthesized to contain (26)Al. The rats received concurrent (27)Al infusion. Blood was repeatedly withdrawn and serum analyzed for (26)Al by accelerator mass spectrometry. Total Al was determined by atomic absorption spectrometry. Oral (26)Al bioavailability was determined from the area under the (26)Al, compared to (27)Al, serum concentrationxtime curves. Oral Al bioavailability (F) from biscuit containing 1% or 2% acidic (26)Al-SALP averaged approximately 0.11% and 0.13%; significantly less than from water, which was previously shown to be approximately 0.3%. The time to maximum serum (26)Al concentration was 4.2 and 6h after consumption of biscuit containing 1% or 2% (26)Al-acidic SALP, respectively, compared to 1-2h following (26)Al in water. These results of oral Al bioavailability from acidic (26)Al-SALP in a biscuit (F approximately 0.1%) and results from (26)Al in water (F approximately 0.3%) x the contributions of food and drinking water to the typical human's daily Al intake ( approximately 5-10mg from food and 0.1mg from water, respectively) suggest food provides approximately 25-fold more Al to systemic circulation, and potential Al body burden, than does drinking water.

Groundnut cake (GNC) and soybean cake (SBC) by-product of agriculture industry had protein and protein digestibility in the range of 42.7-50.5 and 71.3-76.8%, respectively. Polyphenols present in GNC and SBC were cholorogenic acid, syringic acid and p-coumaric acid. The number of bands separated in soybean meal was greater than the bands observed in GNC flour as seen in SDS-PAGE pattern, respectively. SEM of groundnut flour showed distension of protein bodies due to roasting of the oil cakes. The water absorption of wheat flour GNC blends decreased from 59.2 to 57.3% and increased in wheat flour SBC blends from 59.2 to 68.3% with an increase in oil cake from 0 to 20%. With increase in either GNC or SBC, the biscuits became harder. Addition of glycerol monostearate and sodium stearoyl lactylate in combination with 20% blend of GNC/SBC decreased the breaking strength values and increased the sensory parameters of the biscuits. Nutritionally rich biscuits were thus prepared by incorporating GNC/SBC.

This cross-over experimental study aimed to examine the effects of filled chocolate consumption on blood glucose, insulin and ghrelin levels in 20 volunteers. After a one-week run-in period, study participants consumed two chocolate-based products, the tested biscuit or water for 21 days as a morning snack. After a two-week wash-out period, participants consumed another tested food for another 21 days. Each participant consumed all four test foods within an 18-week period. The participants' blood insulin increased slowly after two chocolate-based products intakes on the first day and satiety levels after eating chocolate-based products and the tested biscuit were the same. Chocolate consumption for three weeks had no adverse effects on blood glucose, insulin or ghrelin levels. In conclusion, compared to eating the tested biscuit, 21-day consumption of the tested chocolate-based products had no adverse effects on the blood glucose, insulin and ghrelin levels.

Anthocyanins, water soluble polyphenols, have been associated with several beneficial health effects. The aim of this study was to determine how the baking process and food matrix affect anthocyanin stability and bioaccessibility in bakery products in order to develop functional foods. Three well known regularly consumed bakery products (buns, breadsticks and biscuits) were enriched with anthocyanin (AC) isolated from grape skin alone or in combination with docosahexaenoic acid (AC + DHA) to reveal knowledge on AC as active ingredients in real food systems rather than pure compounds. Anthocyanin amounts added to the formulations of buns, breadsticks and biscuits were 34 mg per 100 g, 40 mg per 100 g and 37 mg per 100 g, respectively. The effect of processing, storage and the food matrix on AC stability and bioaccessibility was investigated. In addition, the sensory properties of bakery products were evaluated. Breadsticks enriched with AC and AC + DHA received the lowest scores in the pre-screening sensory test. Therefore breadsticks were excluded from further analysis. AC retentions, which were monitored by determination of malvidin 3-O-glucoside, in the bun and biscuit after baking were 95.9% (13.6 mg per 100 g) and 98.6% (15.2 mg per 100 g), respectively. Biscuits and buns enriched only with AC showed significantly higher anthocyanin bioaccessibilities (57.26% and 57.30%, respectively) than the same ones enriched with AC + DHA. AC stability in enriched products stored for 21 days was significantly lower than in products stored for 7 days (p products.

This study investigates resources to provide better conditions for oropharyngeal swallowing for improvement in the quality of life of Parkinson's disease patients. Three men and one woman with an average age of 70.25 years had been afflicted with Parkinson's disease for an average of 9.25 years. The patients were submitted to a rehabilitation program for oropharyngeal dysphagia after a clinical evaluation of swallowing. The rehabilitation program consisted of daily sessions for two consecutive weeks during which a biofeedback resource adapted especially for this study was used. The patients were then reevaluated for swallowing ability at follow-up. The patients presenting difficulties with swallowing water displayed no such problems after rehabilitation. Only one patient exhibited slow oral transit of food and other discrete oropharyngeal food remnants when swallowing a biscuit. The sample variance was used to analyze the pressure measurements, demonstrating a numerical similarity of the results obtained with the swallowing of saliva or of biscuits (VAR = 4.41). A statistical difference was observed between the swallowing of saliva and biscuits, showing a significant pressure increase at the end of the rehabilitation program (p dysphagia in Parkinson's disease patients.

Full Text Available The aim of this research was to study the variation of shelf-life values, obtained in quantifying shelf-life of biscuits among models of accelerated storage studies (ASS from unidirectional Fick’S law. Shelf-life of biscuits is defined as the length of time of a packaged biscuits can be stored before the onset quality change appears.Four models: Heiss-Eichner (1971, Labuza (1983, Rudolph (1986 and Half Value Period or HVP model (Syarief, 1986 were evaluated. These models shared a common basic principle that they were all derived and developed from unidirectional Fick’s law. Therefore, each parameter of individual model can be compared to the athers. A semi empirical approach using reaction kinetics through Arrhenius plot was used as a real shelf-life values.Quantification resulted in two categories of shelf-life values, First those which higher than expected value and second, were lower than expected. Parameter evaluation of components of Heiss-Eichner and Labuza models clearly shown less in number than components of Rudolph and HVP models. This led to a conclusion that the more sophisticated models gave higher shelf-life values as compared to the Arhenius model.

. In the few experiments conducted on tiles with attached mortar, the mortar was desalinated to a higher degree than the biscuit and successful desalination of the biscuit through the mortar requires further research. In-situ pilot scale tests were performed on highly salt-contaminated walls without tiles...... by placing electrodes at the same side of the wall. Thus it may be possible to desalinate tile panels, without any physical damage of the fragile glaze, by placing electrodes on the back of the wall or by removing some tiles, placing electrodes in their spaces, and extracting the salts from there before...... the tiles are placed back again....

Immersive virtual reality techniques present new opportunities for research into consumer behavior. The current study examines whether the increased realism of a virtual store compared to pictorial (2D) stimuli elicits consumer behavior that is more in line with behavior in a physical store. We examine the number, variety, and type of products selected, amount of money spent, and responses to price promotions and shelf display, in three product categories (fruit & vegetables, milk, and biscuits). We find that virtual reality elicits behavior that is more similar to behavior in the physical store compared to the picture condition for the number of products selected (Milk: M store  = 1.19, M virtual  = 1.53, M pictures  = 2.58) and amount of money spent (Milk: M store  = 1.27, M virtual  = 1.53, M pictures  = 2.60 Euro), and for the selection of products from different areas of the shelf, both vertically (purchases from top shelves, milk and biscuits: P store  = 21.6%, P virtual  = 33.4%, P pictures  = 50.0%) and horizontally (purchase from left shelf, biscuits: P store  = 35.5%, P virtual  = 53.3%, P pictures  = 66.7%). This indicates that virtual reality can improve realism in responses to shelf allocation. Virtual reality was not able to diminish other differences between lab and physical store: participants bought more products and spent more money (for biscuits and fruit & vegetables), bought more national brands, and responded more strongly to price promotions in both virtual reality and pictorial representations than in the physical store. Implications for the use of virtual reality in studies of consumer food choice behavior as well as for future improvement of virtual reality techniques are discussed. Copyright © 2016 Elsevier Ltd.

Full Text Available In the furniture industry, the joining points of frame and box construction furniture according to the loads to be affected by the use place is important for the security of the user and service life of the furniture element. In this direction, it is aimed to determine the diagonal compression and diagonal tensile moment values of "L" type corner joints of box framed construction furniture prepared from solid wood materials. The Pinus Nigra, Fagus Orientalis L and Populus Nigra were used as solid wood materials. Wood-based biscuit joining elements were used in corner joints of the test construction and epoxy resin was used as glue for materials. The static loads were applied to construction according to ASTM-D1037. The results show that, the highest tensile and compression values were obtained from Fagus Orientalis L and the lowest values were obtained from Populus Nigra specimens. In the statistical study, the difference between the tensile and compressive bending moment values of the biscuit connection element was found to be statistically significant. This study indicates that, it is suggested to use of L type joints prepared from Fagus Orientalis L by using epoxy resin and wood based biscuit joining element in frame constructions.

Lead is a common neurotoxicant and its absorption may be increased in iron deficiency (ID). Thus, iron fortification to prevent ID in populations is a promising lead mitigation strategy. Two common fortificants are ferrous sulfate (FeSO 4 ) and ferric sodium EDTA (NaFeEDTA). EDTA can chelate iron and lead. Our study objective was to determine the effects of iron and EDTA, alone and in combination, on blood lead (BPb) concentration, iron status, and cognition. In this 2 × 2 factorial, double-blind placebo-controlled trial, 457 lead-exposed Moroccan children were stratified by school and grade and randomly assigned to consume biscuits (6 d/wk at school) containing 1) ∼8 mg Fe as FeSO 4 , 2) ∼8 mg Fe as NaFeEDTA that contained ∼41 mg EDTA, 3) ∼41 mg EDTA as sodium EDTA (Na 2 EDTA), or 4) placebo for 28 wk. The primary outcome was BPb concentration; secondary outcomes were iron status and cognitive outcomes from subtests of the Kaufman Assessment Battery for Children and the Hopkins Verbal Learning Test. These outcomes were measured at baseline and endpoint. All data were analyzed by intention-to-treat. The adjusted geometric mean BPb concentration at baseline was 4.3 μg/dL (95% CI: 4.2, 4.3 μg/dL), and at endpoint these values were 3.3 μg/dL (95% CI: 3.1, 3.5 μg/dL) for FeSO 4 , 2.9 μg/dL (95% CI: 2.7, 3.0 μg/dL) for NaFeEDTA, 3.3 μg/dL (95% CI: 3.1, 3.5 μg/dL) for EDTA, and 3.7 μg/dL (95% CI: 3.5, 3.9 μg/dL) for placebo. We found an effect of iron (P = 0.009) and EDTA (P = 0.012) for reduced BPb concentrations at endpoint, but no iron × EDTA interaction. Iron fortification improved iron status, but there were no positive effects of iron or EDTA on cognitive test scores. Food fortification with iron and EDTA additively reduces BPb concentrations. Our findings suggest that NaFeEDTA should be the iron fortificant of choice in lead-exposed populations. This trial was registered at clinicaltrials.gov as NCT01573013. © 2016 American Society for

2011-02-01

Defatted groundnut cake obtained from commercial oil processing units and that prepared in laboratory oil expeller (LOE) were analyzed for quality parameters. Defatted groundnut cake flour (DGCF) was incorporated at 15-100% levels in laddoo, chutney powder, fryums (deep fried crisp and crunchy item), biscuits, noodles and extruded snacks. The products were studied for sensory, physico-chemical and shelf-life quality. DGCF was creamish white with bulk density of 0.55 ± 0.03 g/ml, water absorption capacity 135.6 ± 1.97 ml %, oil absorption capacity 100.3 ± 1.16 ml % and foam capacity 33 ± 1%. Protein, fat and ash contents were 51.6 ± 0.06, 4.5 ± 0.05 and 4.2 ± 0.11%, respectively. Tannins and aflatoxin B1 were not detected. The increase of protein due to incorporation of DGCF into the products ranged from 5.5 to 21.9%. Shelf-life studies indicated the maximum storability for 90 days for all the products except laddoo, which could be stored for 30 days at ambient temperature (28 ± 2°C). All the products were acceptable and the order of preference for the products as indicated by adults (fryums, chutney powder, extruded snacks, noodles, biscuits and laddoo) and children (biscuits, laddoo, extruded snacks, fryums, noodles and chutney powder) varied.

We describe a new species of sexually dimorphic brittle star, Ophiodaphne spinosa, from Japan associated with the irregular sea urchin, Clypeaster japonicus based on its external morphology, and phylogenetic analyses of mitochondrial COI (cytochrome c oxidase subunit I). Females of this new species of Ophiodaphne are characterized mainly by the presence of wavy grooves on the surface of the radial shields, needle-like thorns on the oral skeletal jaw structures, and a low length-to-width ratio of the jaw angle in comparison with those of type specimens of its Ophiodaphne congeners: O. scripta, O. materna, and O. formata. A tabular key to the species characteristics of Ophiodaphne is provided. Phylogenetic analyses indicate that the new species of Ophiodaphne, O. scripta, and O. formata are monophyletic. Our results indicate that the Japanese Ophiodaphne include both the new species and O. scripta, and that there are four Ophiodaphne species of sexually dimorphic brittle stars with androphorous habit.

Effectiveness of methods for reducing acrylamide in bakery products.

Sadd, Peter A; Hamlet, Colin G; Liang, Li

2008-08-13

Pilot-scale bread, biscuit, and cracker doughs have been baked to assess how well recipe changes could reduce acrylamide in commercial bakery products. Removing ammonium-based raising agents was beneficial in biscuits. In doughs, long yeast fermentations were an effective way of reducing asparagine levels and hence acrylamide. At moderate fermentation times fructose levels increased, but the yeast later absorbed this, so the net effect on acrylamide was beneficial. Metal ions such as calcium reduced acrylamide when added as the carbonate or chloride. Hence, the fortification of flour with calcium carbonate, over and above its natural mineral content, has an additional benefit. However, some other possible methods of adding calcium to bakery doughs, for example, via the permitted preservative calcium propionate, were not beneficial. Amino acid addition to doughs gave modest reductions in acrylamide. Lowering the dough pH reduced acrylamide, but at the expense of higher levels of other process contaminants such as 3-monochloropropane-1,2-diol (3-MCPD).

Every body has to eat to survive but it becomes a matter of great concern, when the life provider food becomes an asphyxiating agent. In this case, a 60-year-old woman choked herself while swallowing biscuits. On autopsy examination, biscuits were found lodged in larygo-pharynx. Brain showed marked dystrophy and loosened lusterless white matter. On histopathologic examination, brain tissue had numerous eosinophilic globules representing astrocytic processes called "Rosenthal fibers"; hence, it was diagnosed as a case of Alexander dystrophy. It is a disease of white matter, where there is a progressive degeneration of the white matter of the brain because of imperfect growth or development of the myelin sheath. The histopathology of brain showed Rosenthal fibers in abundance. This is one of the rarest disease in which choking can occur because of lack of nervous and muscular coordination and weakness. Its specific relation to choking is documented in this report.

Effects of certain polyphenols and extracts on furans and acrylamide formation in model system, and total furans during storage.

Oral, Rasim Alper; Dogan, Mahmut; Sarioglu, Kemal

2014-01-01

Using a glucose-glycine and asparagine-fructose system as a Maillard reaction model, the effects of seven polyphenols and solid phase extracts of three plants on the formation of furans and acrylamide were investigated. The polyphenols and extracts were used in biscuit formulation and acrylamide formation was observed. They were used for the storage of the glycine-glucose model system at three different temperatures. The addition of some of the extracts and polyphenols significantly decreased furan formation to different extents. All phenolic compounds and plant extracts decreased in the range of 30.8-85% in the model system except for oleuropein, and all of them decreased in the range of 10.3-19.2% in biscuit. Total furan formation was inhibited by caffeic acid, punicalagin, epicatechin, ECE and PPE during storage. This study evaluated and found the inhibitory effect on the formation of furans and acrylamide in Maillard reactions by the use of some plant extracts and polyphenols. Copyright © 2013 Elsevier Ltd.

Acrylamide is a well-known potentially carcinogen compound formed during thermal processing as an intermediate of Maillard reactions. Three objectives were addressed: the impact of gastric digestion on acrylamide content of French Fries, chips, chicken nuggets, onions rings, breakfast cereals, biscuits, crackers, instant coffee and coffee substitute; the acrylamide content evolution during gastrointestinal digestion of French fries and chips; and the effectiveness of blanching and air-frying on acrylamide mitigation after gastrointestinal digestion. A significant increase (p-value digestion (maximum registered for sweet biscuits, from 30±8 to 150±48µg/kg). However, at the end of the intestinal stage, acrylamide values were statistically similar (p-value=0.132) for French fries and lower than the initial values (before digestion) in potato chips (p-value=0.027). Finally, the low acrylamide content found in blanched and air-fried samples, remained still lower than for deep fried samples even after gastrointestinal digestion. Copyright © 2017 Elsevier Ltd.

It was supposed to be an amicable "merger of equals," an example of European togetherness, a synergistic deal that would create the world's second-largest consumer foods company out of two former competitors. But the marriage of entrepreneurial powerhouse Royal Biscuit and the conservative, family-owned Edeling GmbH is beginning to look overly ambitious. Integration planning is way behind schedule. Investors seem wary. But for Royal Biscuit HR head Michael Brighton, the most immediate problem is that he can't get his German counterpart, Dieter Wallach, to collaborate on a workable leadership development plan for the merged company's executives. And stockholders have been promised details of the new organizational structure, including a precise timetable, in less than a month. The CEO of the British company--and of the postmerger Royal Edeling--is furious. It's partly a culture clash, but the problems may run deeper than that. The press is harping on details that counter the official merger-of-equals line. For instance, seven of the ten seats on the new company's management board will be held by Royal Biscuit executives. Will the clash of cultures undermine this cross-border merger? Commenting on the fictional case study are Robert F. Bruner, the executive director of the Batten-Institute at the University of Virginia's Darden Graduate School of Business Administration in Charlottesville; Leda Cosmides and John Tooby, the codirectors of the Center for Evolutionary Psychology at the University of California, Santa Barbara; Michael Pragnell, the CEO and director of the board for the agribusiness firm Syngenta, based in Basel, Switzerland; and David Schweiger, the president of the Columbia, South Carolina--based management consulting firm Schweiger and Associates.

The costs and cost-efficiency of providing food through schools in areas of high food insecurity.

The provision of food in and through schools has been used to support the education, health, and nutrition of school-aged children. The monitoring of financial inputs into school health and nutrition programs is critical for a number of reasons, including accountability, transparency, and equity. Furthermore, there is a gap in the evidence on the costs, cost-efficiency, and cost-effectiveness of providing food through schools, particularly in areas of high food insecurity. To estimate the programmatic costs and cost-efficiency associated with providing food through schools in food-insecure, developing-country contexts, by analyzing global project data from the World Food Programme (WFP). Project data, including expenditures and number of schoolchildren covered, were collected through project reports and validated through WFP Country Office records. Yearly project costs per schoolchild were standardized over a set number of feeding days and the amount of energy provided by the average ration. Output metrics, such as tonnage, calories, and micronutrient content, were used to assess the cost-efficiency of the different delivery mechanisms. The average yearly expenditure per child, standardized over a 200-day on-site feeding period and an average ration, excluding school-level costs, was US$21.59. The costs varied substantially according to choice of food modality, with fortified biscuits providing the least costly option of about US$11 per year and take-home rations providing the most expensive option at approximately US$52 per year. Comparisons across the different food modalities suggested that fortified biscuits provide the most cost-efficient option in terms of micronutrient delivery (particularly vitamin A and iodine), whereas on-site meals appear to be more efficient in terms of calories delivered. Transportation and logistics costs were the main drivers for the high costs. The choice of program objectives will to a large degree dictate the food modality

Anemia is a significant public health problem among schoolchildren in Vietnam. Food fortification is considered one of the most sustainable long-term strategies to control iron-deficiency anemia in Vietnam. The success of a food-fortification program depends on the choice of the food vehicle. The aim of the present study was to identify an appropriate vehicle for iron fortification to be used in a school-feeding program aimed at improving the iron and anemia status of schoolchildren in rural Vietnam. Children 6 to 8 years of age in two primary schools in Tam Nong District, Phu Tho Province, and their parents were included in this study. The study consisted of three substudies: a food-consumption study with 24-hour recalls of two nonconsecutive days; a food-beliefs study, with focus group discussions, a pile-sorting test, and a food attributes and differences exercise; and a food-acceptance study using noodles and biscuits fortified with sodium iron ethylenediaminetetraacetic acid (NaFeEDTA). The average number of meals consumed daily was 3.2 +/- 0.4, and the average intakes of energy and iron were 1,218 +/- 406 kcal and 7.5 +/- 4.0 mg, respectively. Compared with biscuits and instant rice soup, instant noodles were consumed more frequently and in larger portion sizes and are more acceptable as children's food in the culture of the local people. The iron level of the fortified product did not affect the mean consumption of noodles, but a higher level of iron was associated with a lower mean consumption of biscuits (p noodles; however, during preparation at least 70% of the iron is leaked into the soup. Instant noodles are a suitable vehicle for iron fortification for use in school-based intervention to improve iron-deficiency anemia among primary schoolchildren in rural Vietnam.

Food change due to cooking temperature and unrecognized heat-formed chemical carcinogens may impact on the risk of stomach and colo-rectal cancers. To test this hypothesis a case-control study was performed. A total of 670 cases of stomach and colo-rectal cancers matched with 672 hospital controls for sex and -/+5 years age admitted to three hospitals in Hanoi city in the North Viet Nam from October 2006 to September 2007 were the subjects. Five levels of food change due to cooking temperature were based on food color; white, pale yellow, yellow, dark yellow, and burnt. We asked study subjects to themselves report which of these five colors was their preferable intake before the onset of disease. The present study included; fried fishes-meats-eggs-potato-tofu; grilled foods; roasted foods; sugar, bread, heated wheat, and biscuits. These were cooked at temperatures as high as from 165 to 240 degrees C, based on the literature. Adjusted estimation of odds ratio was conducted controlling for possible confounding factors using STATA 8.0. A high intake of roasted meats, bread and biscuit significantly increased the risk of cancer as much as OR= 1.63, 95%CI= 1.04-2.54; OR= 1.40, 95%CI= 1.03-1.90; OR= 1.60, 95%CI= 1.03-2.46 with probabilities for trend = 0.029, 0.035, and 0.037, respectively. For exposure among controls: 529 (79%) were not exposed at all to roasted meats; 449 (67%) were not exposed at all to bread; and 494 (74%) were not exposed at all to biscuit. Observation of food change due to cooking temperature based on color is practically feasible for detecting associations with risk of developing cancer.

Are sweet snacks more sensitive to price increases than sugar-sweetened beverages: analysis of British food purchase data

Science.gov (United States)

Smith, Richard D; Quirmbach, Diana; Jebb, Susan A

2018-01-01

Objectives Taxing sugar-sweetened beverages (SSBs) is now advocated, and implemented, in many countries as a measure to reduce the purchase and consumption of sugar to tackle obesity. To date, there has been little consideration of the potential impact that such a measure could have if extended to other sweet foods, such as confectionery, cakes and biscuits that contribute more sugar to the diet than SSBs. The objective of this study is to compare changes in the demand for sweet snacks and SSBs arising from potential price increases. Setting Secondary data on household itemised purchases of all foods and beverages from 2012 to 2013. Participants Representative sample of 32 249 households in Great Britain. Primary and secondary outcome measures Change in food and beverage purchases due to changes in their own price and the price of other foods or beverages measured as price elasticity of demand for the full sample and by income groups. Results Chocolate and confectionery, cakes and biscuits have similar price sensitivity as SSBs, across all income groups. Unlike the case of SSBs, price increases in these categories are also likely to prompt reductions in the purchase of other sweet snacks and SSBs, which magnify the overall impact. The effects of price increases are greatest in the low-income group. Conclusions Policies that lead to increases in the price of chocolate and confectionery, cakes and biscuits may lead to additional and greater health gains than similar increases in the price of SSBs through direct reductions in the purchases of these foods and possible positive multiplier effects that reduce demand for other products. Although some uncertainty remains, the associations found in this analysis are sufficiently robust to suggest that policies—and research—concerning the use of fiscal measures should consider a broader range of products than is currently the case.

Autism spectrum disorder (ASD) is characterized by social and communication impairments as well as restricted, repetitive behavior patterns. Despite the fact that ASD is reported worldwide, very little research exists examining ASD characteristics on a multinational scale. Cross-cultural comparisons are especially important for ASD, since cultural differences may impact the perception of symptoms. Identifying behaviors that are similarly reported as problematic across cultures as well as identifying behaviors in which there is cultural variation could aid in the development and refinement of more universally effective measures. The present study sought to examine similarities and differences in caregiver endorsement of symptom severity through scores on the Baby Infant Screen for Children with aUtIsm Traits (BISCUIT). The BISCUIT was utilized to examine ASD core symptomology in 250 toddlers diagnosed with ASD from Greece, Italy, Japan, Poland, and the United States. Significant differences in overall ASD symptom severity and endorsement were found between multinational groups. Implications of the results are discussed. Copyright © 2016 Elsevier Masson SAS.

The compound 3-monochloropropano-1,2-diol, (3-MCPD) is a contaminant found in foodstuffs that arises during food processing and storage. Conditions condusive to the former are low pH and a high temperature and it can also be formed during manufacturing, ie. food processing. Those favouring the latter are dampness, raised temperatures, packaging conditions and storage duration. For the first time, high levels of 3-MCPD have been reported in soy sauces and hydrolysate products of vegetable protein manufactured through using acid hydrolysis. Animal studies on rats and mice have found that 3-MCPD is a carcinogen, however it is not genotoxic. To determine 3-MCPD levels in bakery products currently on the market and to estimate the resulting exposure to the those consumer groups most vulnerable. Results from a two year assessment of this contaminant are so presented. Concentrations of 3-MCPD were measured in 244 samples of bakery foodstuff products found on the market which included; sponge cake, biscuits, cakes, crackers, breadsticks and rusks. Sampling was undertaken by the State Sanitary Inspectorate and analyses were performed by an accredited Gas Chromatography Mass Spectrometry (GC/MS) method. The exposure was assessed by comparing the accepted Tolerable Daily Intake (TDI) for 3-MCPD with the different conditions it occurred in, the consumption of 3-MCPD in the aforementioned foodstuffs and the various consumer groups. Levels of 3-MCPD that exceeded the limits of quantification in the studied foodstuffs were found in 91 out of 244 samples, (ie. 37.3%). These samples included 11 sponge cakes (11.3%), 27 biscuits (55.2%), 10 crackers (8.33%), 17 breadsticks (8.93%), 21 rusks (63.6%) and 5 cakes (3.13%). The highest numbers of samples containing more than 10 (> or = 10) microg/ kg of 3-MCPD were successively found in the following; breadsticks (79%), biscuits (75%), rusks (33%), crackers (33%), cakes (31%), biscuits (24%) and sponge cakes (4%).

Background: There are conflicting views in the literature as to whether vitamin D 2 and vitamin D 3 are equally effective in increasing and maintaining serum concentrations of 25-hydroxyvitamin D [25(OH)D], particularly at lower doses of vitamin D. Objective: We aimed to investigate whether vitamin D 2 or vitamin D 3 fortified in juice or food, at a relatively low dose of 15 μg/d, was effective in increasing serum total 25(OH)D and to compare their respective efficacy in South Asian and white European women over the winter months within the setting of a large randomized controlled trial. Design: A randomized, double-blind, placebo-controlled food-fortification trial was conducted in healthy South Asian and white European women aged 20-64 y ( n = 335; Surrey, United Kingdom) who consumed placebo, juice supplemented with 15 μg vitamin D 2 , biscuit supplemented with 15 μg vitamin D 2 , juice supplemented with 15 μg vitamin D 3 , or biscuit supplemented with 15 μg vitamin D 3 daily for 12 wk. Serum 25(OH)D was measured by liquid chromatography-tandem mass spectrometry at baseline and at weeks 6 and 12 of the study. Results: Postintervention in the 2 ethnic groups combined, both the vitamin D 3 biscuit and the vitamin D 3 juice groups showed a significantly greater absolute incremental change (Δ) in total 25(OH)D when compared with the vitamin D 2 biscuit group [Δ (95% CI): 15.3 nmol/L (7.4, 23.3 nmol/L) ( P < 0.0003) and 16.0 nmol/L (8.0, 23.9 nmol/L) ( P < 0.0001)], the vitamin D 2 juice group [Δ (95% CI): 16.3 nmol/L (8.4, 24.2 nmol/L) ( P < 0.0001) and 16.9 nmol/L (9.0, 24.8 nmol/L) ( P < 0.0001)], and the placebo group [Δ (95% CI): 42.3 nmol/L (34.4, 50.2 nmol/L) ( P < 0.0001) and 42.9 nmol/L (35.0, 50.8 nmol/L) ( P < 0.0002)]. Conclusions: With the use of a daily dose of vitamin D relevant to public health recommendations (15 μg) and in vehicles relevant to food-fortification strategies, vitamin D 3 was more effective than vitamin D 2 in increasing

Acrylamide (AA) levels in conventional (n = 112) and traditional (n = 43) Colombian foods were analysed by gas chromatography with mass spectrometry (GC/MS) detection. Samples included: infant powdered formula, coffee and chocolate powders, corn snacks, bakery products and tuber-, meat- and vegetable-based foods. There was a wide variability in AA levels among different foods and within different brands of the same food, especially for coffee powder, breakfast cereals biscuits and French fries samples. Among the conventional foods tested, the highest mean AA value was found in bakery products, such as biscuit (1104 µg kg(-1)) and wafer (1449 µg kg(-1)), followed by potato chips (916 µg kg(-1)). On the other hand, among the traditional foods, higher AA amounts were detected in fried platano (2813 µg kg(-1)) and yuca (3755 µg kg(-1)) compared to other products. Interestingly, the arepa, a traditional Colombian bakery product made with corn flour, showed a lower AA content (< 75 µg kg(-1)) when compared with similar bakery products tested, such as soft bread (102-594 µg kg(-1)), which is a made with wheat flour.

Taxing sugar-sweetened beverages (SSBs) is now advocated, and implemented, in many countries as a measure to reduce the purchase and consumption of sugar to tackle obesity. To date, there has been little consideration of the potential impact that such a measure could have if extended to other sweet foods, such as confectionery, cakes and biscuits that contribute more sugar to the diet than SSBs. The objective of this study is to compare changes in the demand for sweet snacks and SSBs arising from potential price increases. Secondary data on household itemised purchases of all foods and beverages from 2012 to 2013. Representative sample of 32 249 households in Great Britain. Change in food and beverage purchases due to changes in their own price and the price of other foods or beverages measured as price elasticity of demand for the full sample and by income groups. Chocolate and confectionery, cakes and biscuits have similar price sensitivity as SSBs, across all income groups. Unlike the case of SSBs, price increases in these categories are also likely to prompt reductions in the purchase of other sweet snacks and SSBs, which magnify the overall impact. The effects of price increases are greatest in the low-income group. Policies that lead to increases in the price of chocolate and confectionery, cakes and biscuits may lead to additional and greater health gains than similar increases in the price of SSBs through direct reductions in the purchases of these foods and possible positive multiplier effects that reduce demand for other products. Although some uncertainty remains, the associations found in this analysis are sufficiently robust to suggest that policies-and research-concerning the use of fiscal measures should consider a broader range of products than is currently the case. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Consumption of industrially produced trans-fatty acids (TFAs is a well-established health risk factor that correlates with the increased risk of developing cardiovascular disease. The recommended TFA intake is as low as possible, within the context of a nutritionally adequate diet. Different countries have introduced different measures to minimize the exposure of their population to TFAs. Previous data have shown that TFA content has significantly decreased in Western European countries, while this was not the case in many Central-Eastern European countries, including Slovenia. In the absence of regulatory requirements, a number of awareness campaigns were launched in Slovenia since 2015, with the common goal of lowering the use of partially hydrogenated oils (PHO, which are considered a major source of TFAs. To determine if this goal had been reached, we performed an assessment of the exposure of the population to prepacked foods containing PHOs in years 2015 and 2017. Altogether, data on the composition of 22,629 prepacked foods was collected from food labels, using a specifically developed smartphone application. Furthermore, the food categories with the most frequent use of PHOs were identified. The proportion of PHO-containing products was determined for each specific food category, and adjusted with the market share data. The results showed that in 2015, vegetable cream substitutes, soups, and biscuits were the categories with the highest penetration of declared PHO content. In 2017, the proportion of products with PHO decreased considerably. In vegetable cream substitutes the percentage of PHO containing items dropped from 30 down to 4%, in soups it decreased from 21 to 5%, in biscuits from 17 to 8%, and in crisps and snacks from 10 to 4%. However, PHO content remained notable among cakes, muffins, pastries, and biscuits. We can conclude that the voluntary guidelines and regular public communication of the risks related to the TFA

Identifying objective markers of diet would be beneficial to research fields such as nutritional epidemiology. As a preliminary study on the validity of using saliva for this purpose, and in order to explore the relationship between saliva and diet, we focused on clearly contrasted groups of children: children with eating difficulties (ED) receiving at least 50% of their energy intake through artificial nutrition vs healthy controls (C). Saliva of ED and C children was analyzed by various methods (targeted biochemical analyses, 2-D electrophoresis coupled to MS, 1 H NMR) and their diet was characterized using food frequency questionnaires, considering 148 food items grouped into 13 categories. Complete datasets were obtained for 16 ED and 16 C subjects (median age 4.7y and 5.0y, respectively) and the statistical link between salivary and dietary characteristics was studied by Multiple Factor Analysis (MFA). Overall, ED children showed as expected lower consumption frequency scores and higher food selectivity. The two groups of children differed in "diet/saliva" associations. Some distinctive salivary variables were common to both groups of children. For example, carbonic anhydrase 6 and the consumption frequency of biscuits & sweets and drinks were positively associated with the MFA axis 1 in C children, but oppositely associated in ED children. Specifically for ED children, abundant salivary proteins (cystatins, amylase, amylase fragments) and some metabolites (amino acids, galactose, lactate) correlated with axis 1, together with the consumption frequency of sauces & seasonings, bread & cereal products, ready-to-eat meals, fish, biscuits & sweets, drinks and potatoes. Specifically for C children, several proteins (serum albumin, haptoglobin, Igκ, apolipoprotein A-1, α-1 antitrypsin) correlated with axis 1, together with the consumption frequency of biscuits & sweets, milk & dairy products, drinks, fruit, meat and vegetables. This study demonstrates that the

Front-of-pack (FOP) nutrition labelling has received growing attention from public health authorities, as a tool to promote healthier diets in the population. Recently, the French Health law introduced the principle of implementing a FOP nutrition labelling system. A scientific proposal has put forward the 5-Colour Nutrition Label (5-CNL), a five-category colour-coded summary system supported by research suggesting that it is well perceived and understood in the population. Our objective was to investigate the impact of the 5-CNL on the nutritional quality of purchases in experimental supermarkets. Participants (n = 901) were recruited using quota sampling between September and December 2015 and evenly distributed in three experimental conditions: 1) control situation; 2) Application of the 5-CNL on all food products in three specific sections: breakfast cereals, sweet biscuits and appetizers; 3) introduction of the 5-CNL accompanied by consumer information on use and understanding of the label. Main outcome was the nutritional quality of the shopping cart in the three sections combined, measured using the United Kingdom Food Standards Agency nutrient profiling system (FSA score). Significantly higher mean nutritional quality of the purchased items per section were observed for the sweet biscuits category in the intervention combining the label + communication (overall FSA score 21.01 vs. 20.23, P = 0.02). No significant effects were observed for the general mean over the three sections combined or other food categories. The results observed on purchase may be related to the high level of recall, self-reported and objective understanding of the label that were observed in the intervention groups as they are pre-requisites for use of a label in purchasing situations. These results suggest that the 5-CNL FOP nutrition label may have a limited impact on purchases, leading to healthier food choices in some food categories such as sweet biscuits. The trial

Cross-sectional National Nutrition Survey, 1995. Australia. SUBJECTS ON SCHOOL DAYS: A total of 1656 children aged 5-15 y who had weekday 24-h dietary recall data. An average of 37% of total energy intake was consumed at school. Energy-dense foods and beverages such as fat spreads, packaged snacks, biscuits and fruit/cordial drinks made a greater contribution to energy intake at school compared to out of school (Pfoods and soft drinks contributed 11 and 3% of total energy intake; however, these food groups were mostly consumed out of school. Fruit intake was low and consumption was greater in school. In all, 14% of children purchased food from the canteen and they obtained more energy from fast food, packaged snacks, desserts, milk and confectionary (Pfoods and beverages are over-represented in the Australian school environment. To help prevent obesity and improve nutrition in schools, biscuits, snack bars and fruit/cordial drinks brought from home and fast food, packaged snacks, and confectionary sold at canteens should be replaced with fruit and water.

To compare the effects of feeding diets varying in the proportions of macronutrients on the digestibility, post-prandial endocrine responses and large intestinal fermentation of carbohydrate in working dogs. The apparent digestibility of two test diets, one comprising low-carbohydrate, high-protein dry biscuits (Diet 1), and one comprising high-carbohydrate, low-protein dry biscuits (Diet 2), fed to 12 adult Harrier Hounds (n=5 female), was determined using the indigestible-marker and total-collection methods. Serial breath samples were collected from each dog before and after feeding, and analysed for concentrations of hydrogen. Concentrations of glucose and insulin in plasma were established from serial blood samples obtained after feeding. The apparent dry matter, protein, fat and energy digestibility of Diet 1 were higher, but the carbohydrate digestibility was lower (pdogs occurred earlier for Diet 1 than Diet 2 (pdogs fed Diet 2 than Diet 1 (pdogs fed Diet 2 compared with those fed Diet 1 (pdogs, including higher apparent nutrient digestibility, slower release of glucose into the bloodstream, and reduced large intestinal fermentation of carbohydrate. A low-carbohydrate, high-protein diet may be beneficial for specific groups of dogs, including working dogs subjected to prolonged bouts of exercise requiring a sustained energy source, or those with diabetes mellitus requiring better glycaemic control.

Control of final moisture content of food products baked in continuous tunnel ovens

Science.gov (United States)

McFarlane, Ian

2006-02-01

There are well-known difficulties in making measurements of the moisture content of baked goods (such as bread, buns, biscuits, crackers and cake) during baking or at the oven exit; in this paper several sensing methods are discussed, but none of them are able to provide direct measurement with sufficient precision. An alternative is to use indirect inferential methods. Some of these methods involve dynamic modelling, with incorporation of thermal properties and using techniques familiar in computational fluid dynamics (CFD); a method of this class that has been used for the modelling of heat and mass transfer in one direction during baking is summarized, which may be extended to model transport of moisture within the product and also within the surrounding atmosphere. The concept of injecting heat during the baking process proportional to the calculated heat load on the oven has been implemented in a control scheme based on heat balance zone by zone through a continuous baking oven, taking advantage of the high latent heat of evaporation of water. Tests on biscuit production ovens are reported, with results that support a claim that the scheme gives more reproducible water distribution in the final product than conventional closed loop control of zone ambient temperatures, thus enabling water content to be held more closely within tolerance.

Full Text Available Chocolate is a confectionery product, mainly containing cocoa mass or liquor, cocoa butter (CB and sugar. Nowadays vegetable fats and modified oil are used instead of CB in chocolate products to lower the cost and to obtain the varieties of products with different characteristics and textures. Cocoa butter-like fat from modified palm oil (CBFMPO at different levels of CB replacement (60,80 and 100% were used to develop a formulation of coating chocolate.

A high throughput, high-sensitivity procedure, involving simultaneous microwave-assisted extraction (MAS) and unsaponifiable extraction, followed by on-line liquid chromatography (LC)-gas chromatography (GC), has been optimised for rapid and efficient extraction and analytical determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in cereal-based products of different composition. MAS has the advantage of eliminating fat before LC-GC analysis, allowing an increase in the amount of sample extract injected, and hence in sensitivity. The proposed method gave practically quantitative recoveries and good repeatability. Among the different cereal-based products analysed (dry semolina and egg pasta, bread, biscuits, and cakes), egg pasta packed in direct contact with recycled paperboard had on average the highest total MOSH level (15.9 mg kg(-1)), followed by cakes (10.4 mg kg(-1)) and bread (7.5 mg kg(-1)). About 50% of the pasta and bread samples and 20% of the biscuits and cake samples had detectable MOAH amounts. The highest concentrations were found in an egg pasta in direct contact with recycled paperboard (3.6 mg kg(-1)) and in a milk bread (3.6 mg kg(-1)). Copyright © 2015 Elsevier Ltd.

Full Text Available One strategy for examining effects of nutrients on cognitive function is to initially investigate foods that contain many different nutrients. If effects are demonstrated with these foods then further studies can address the role of specific nutrients. Breakfast foods (e.g., cereals, dairy products and fruit provide many important nutrients and consumption of breakfast has been shown to be associated with beneficial effects on cognitive function. Isolating effects of specific constituents of breakfast has proved more difficult and it is still unclear what impact breakfast has on real-life performance. The present study provided initial information on associations between breakfast consumption and cognitive failures and accidents. A second aim was to examine associations between consumption of snacks which are often perceived as being unhealthy (chocolate, crisps and biscuits. A sample of over 800 nurses took part in the study. The results showed that frequency of breakfast consumption (varied breakfasts: 62% cereal was associated with lower stress, fewer cognitive failures, injuries and accidents at work. In contrast, snacking on crisps, chocolate and biscuits was associated with higher stress, more cognitive failures and more injuries outside of work. Further research requires intervention studies to provide a clearer profile of causality and underlying mechanisms.

School feeding is a popular intervention that has been used to support the education, health and nutrition of school children. Although the benefits of school feeding are well documented, the evidence on the costs of such programs is remarkably thin. Address the need for systematic estimates of the cost of different school feeding modalities, and of the determinants of the considerable cost variation among countries. WFP project data, including expenditures and number of schoolchildren covered, were collected for 78 projects in 62 countries through project reports and validated through WFP Country Office records. Yearly project costs per schoolchild were standardized over a set number of feeding days and the amount of energy provided by the average ration. Output metrics, such as tonnage, calories, and micronutrient content, were used to assess the cost-efficiency of the different delivery mechanisms. The standardized yearly average school feeding cost per child, not including school-level costs, was US$48. The yearly costs per child were lowest at US$23 for biscuit programs reaching school-going children and highest at US$75 for take-home rations programs reaching families of schoolgoing children. The average cost of programs combining on-site meals with extra take-home rations for children from vulnerable households was US$61. Commodity costs were on average 58% of total costs and were highest for biscuit and take-home rations programs (71% and 68%, respectively). Fortified biscuits provided the most cost-efficient option in terms of micronutrient delivery, whereas take-home rations were more cost-efficient in terms of food quantities delivered. Both costs and effects should be considered carefully when designing school feeding interventions. The average costs of school feeding estimated here are higher than those found in earlier studies but fall within the range of costs previously reported. Because this analysis does not include school-level costs, these

The research question addressed in this paper is how different reference amounts utilised in front of package nutrition labelling influence evaluation of product healthfulness. A total of 13,117 participants from six European countries (Germany, UK, Spain, France, Poland and Sweden) were recruited via online panels. A mixed between/within-subject factorial design was employed with food (biscuits, sandwiches, yogurts), healthfulness and presence of Guideline Daily Amounts as within-subjects factors and reference amount ('per 100 g', 'typical portion', 'half portion') and country as between-subjects factors. Overall, people correctly ranked foods according to their objective healthfulness as defined by risk nutrients alone, and could distinguish between more and less healthful variants of foods. General healthfulness associations with the three product categories do not appear to have had a strong influence on product ratings. This study shows that where the reference amount of 'per 100 g' is very different from the 'typical' portion size, as was the case for biscuits, products with a 'per 100 g' label are rated significantly less healthful than the 'typical' or 'half typical' portions. The results indicate that across the three food categories, consumers do factor the reference amount, that is, the quantity of food for which the nutritional information is being presented, into their judgements of healthfulness. Therefore, appropriate reference amounts are also of importance for the effective presentation of nutritional information.

Full Text Available OBJECTIVE: To obtain reference values of chewing time of several food textures in young adults. METHOD: descriptive study with a quantitative approach that was developed in a clinical reference, being the population composed of 40 young adults between 18-30 years of age, of both genres. As exclusion criteria: those with neuromuscular and / or degenerative diseases or consequences thereof, as well as subjects who were making use of any orthodontic / orthopedic resource. We conducted a dental evaluation, followed by a clinical assessment. One at a time, the following foods were offered: French bread, wafer biscuit, roasted cashews, for voluntary chewing.  To measure the food chewing time, we used a stopwatch, and this collection procedure was filmed. Data analysis was performed by means of the SPSS statistics 20.0 (IBM® program. RESULTS: There was a statistically significant difference (p < 0.05 between the medians of chewing time of French bread, wafer biscuit and cashew nuts, which were 33.0s (interquartile amplitude 29.0 - 40.0, 10.0s (interquartile amplitude 8.25-12.0 and 18.5s (interquartile amplitude 15.0-23.75, respectively. CONCLUSION: The texture of foods influences the length of mastication. The more rigid is the food, the more cycles and mandibular movements, and therefore the longer the duration of chewing.

Acrylamide is a by-product of the Maillard reaction and is potentially carcinogenic to humans. It is found in a number of foods with higher concentrations in carbohydrate-rich foods and moderate levels of protein-rich foods such as meat, fish and seafood. Acrylamide levels in food distributed in vending machines placed in public areas of the city of Perugia were analysed by high-performance liquid chromatography. Samples included five different categories, depending on the characteristics of the products: i) potato chips; ii) salted bakery products; iii) biscuits and wafers; iv) sweet bakery products; v) sandwiches. A high variability in acrylamide level among different foods and within the same category was detected. Potato chips showed the highest amount of acrylamide (1781±637 μg/kg) followed by salted bakery products (211 ±245 μg/kg), biscuits and wafers (184±254 μg/kg), sweet bakery products (100±72 μg/kg) and sandwiches (42±10 μg/kg). In the potato chips and sandwiches categories, all of the samples revealed the presence of acrylamide, while different prevalence was registered in the other foods considered. The data of this study highlight the presence of acrylamide in different foods sold in vending machines and this data could be useful to understand the contribution of this type of consumption to human exposure to this compound.

In recent years, emotional eating (EmE) has incited substantial research interest as an important psychologic determinant of food intake and overweight. However, little is known about factors that might modulate its relations with dietary habits. The objective of this study was to examine the association between EmE and consumption of energy-dense snack food and assess the 2-way interaction of EmE with sex and depressive symptoms. A total of 7378 men and 22,862 women from the NutriNet-Santé cohort (France, 2009-2013) who completed ≥6 self-reported 24-h food records were included in this cross-sectional analysis. EmE was evaluated via the revised 21-item Three-Factor Eating Questionnaire. Depressive symptoms were assessed by the Center for Epidemiologic Studies Depression Scale. The associations between EmE and energy-dense food consumption were assessed by multivariable logistic and linear regression models adjusted for sociodemographic and lifestyle factors. Higher EmE was associated with higher consumption of energy-dense snacks and, in particular, with consumption of sweet-and-fatty foods across most categories studied. However, these associations were stronger in women with depressive symptoms (e.g., high consumption of chocolate, OR: 1.77, 95% CI: 1.43, 2.20; cakes/biscuits/pastries, OR: 1.81, 95% CI: 1.45, 2.26) compared with those without depressive symptoms (e.g., high consumption of chocolate, OR: 1.52, 95% CI: 1.36, 1.69; cakes/biscuits/pastries, OR: 1.44, 95% CI: 1.29, 1.61). In contrast, the significant positive associations observed in men without depressive symptoms (e.g., high consumption of chocolate, OR: 1.33, 95% CI: 1.16, 1.52; cakes/biscuits/pastries, OR: 1.28, 95% CI: 1.11, 1.48) were not found in men with depressive symptoms. In conclusion, in women, EmE was positively associated with consumption of energy-dense snack food, particularly in those with depressive symptoms. For men, the relation between EmE and energy-dense snack foods was

The Mastication Observation and Evaluation (MOE) instrument was developed to allow objective assessment of a child's mastication process. It contains 14 items and was developed over three Delphi rounds. The present study concerns the further development of the MOE using the COSMIN (Consensus based Standard for the Selection of Measurement Instruments) and investigated the instrument's internal consistency, inter-observer reliability, construct validity and floor and ceiling effects. Consumption of three bites of bread and biscuit was evaluated using the MOE. Data of 59 healthy children (6-48 mths) and 38 children (bread) and 37 children (biscuit) with cerebral palsy (24-72 mths) were used. Four items were excluded before analysis due to zero variance. Principal Components Analysis showed one factor with 8 items. Internal consistency was >0.70 (Chronbach's alpha) for both food consistencies and for both groups of children. Inter-observer reliability varied from 0.51 to 0.98 (weighted Gwet's agreement coefficient). The total MOE scores for both groups showed normal distribution for the population. There were no floor or ceiling effects. The revised MOE now contains 8 items that (a) have a consistent concept for mastication and can be scored on a 4-point scale with sufficient reliability and (b) are sensitive to stages of chewing development in young children. The removed items are retained as part of a criterion referenced list within the MOE. Copyright © 2014 Elsevier Ltd. All rights reserved.

Dietary fiber has recently received recognition for reducing the risk of developing diabetes and heart disease. The implication is that it may have therapeutic benefit in prediabetic metabolic conditions. To test this hypothesis, we investigated the effect of supplementing a high-carbohydrate diet with fiber from Konjac-mannan (KJM) on metabolic control in subjects with the insulin resistance syndrome. We screened 278 free-living subjects between the ages of 45 and 65 years from the Canadian-Maltese Diabetes Study. A total of 11 (age 55+/-4 years, BMI 28+/-1.5 kg/m2) were recruited who satisfied the inclusion criteria: impaired glucose tolerance, reduced HDL cholesterol, elevated serum triglycerides, and moderate hypertension. After an 8-week baseline, they were randomly assigned to take either KJM fiber-enriched test biscuits (0.5 g of glucomannan per 100 kcal of dietary intake or 8-13 g/day) or wheat bran fiber (WB) control biscuits for two 3-week treatment periods separated by a 2-week washout. The diets were isoenergetic, metabolically controlled, and conformed to National Cholesterol Education Program Step 2 guidelines. Serum lipids, glycemic control, and blood pressure were the outcome measures. Decreases in serum cholesterol (total, 12.4+/-3.1%, PFasting blood glucose, insulin, triglycerides, HDL cholesterol, and body weight remained unchanged. A diet rich in high-viscosity KJM improves glycemic control and lipid profile, suggesting a therapeutic potential in the treatment of the insulin resistance syndrome.

New Approach on Sunflower Seeds Processing: Kernel with Several Technological Applications, Husks Package, Different Fat Content Tahini and Halva Properties

Directory of Open Access Journals (Sweden)

Vlad Mureşan

2015-11-01

Full Text Available Sunflower is the basic oil-crop in Central and Eastern Europe. As sunflower seeds are mainly used for oil production, the most of the kernels available on the market show high oil content (>55%. Consequently, when sunflower kernel paste (tahini is used in different food products, oil exudation occurs.The aim of current work was to use entirely the sunflower seeds by partially defatting and obtaining different fat content sunflower pastes with multiple food applications, while using the husks for developing an ecological package. Sunflower kernels were industrially roasted in a continuous roasting drum.  Raw and roasted kernels were pressed at pilot plant scale by using a laboratory expeller. Partially defatted sunflower paste was obtained from the press cakes by employing a ball mill. Different fat content tahini samples were obtained by adding the required amount of oil to the partially defatted paste. Tahini samples fat content ranged from 45 to 60%. Tahini and halva were chosen as a study model. Decreasing tahini oil content increased its colloidal stability during storage, a similar trend being noticed when halva samples were stored. Moreover, halva texture analysis and sensory characteristics were assessed for selecting the optimum tahini oil content and thermal treatment. Various sunflower kernel food applications were proposed by obtaining the related prototypes at pilot plant scale: roasted sunflower kernel biscuits, sunflower spreadable cream filled biscuits, hummus, sunflower paste coated in chocolate, sunflower kernel chikki and bars, as well as an innovative ecological package based on the resulting sunflower husks and a starch adhesive.

Recently, school meal composition regulations have been implemented in France in order to improve the nutritional status of children. The present study investigated the link between school lunch attendance and the food intakes of schoolchildren aged 3-17 years. Second French cross-sectional dietary survey (2006-2007). Eating frequencies were assessed for twenty-four food groups with a 7 d food record. Eating locations were recorded for main meals. Food group intakes at weekday lunches were compared for the school canteen and for other locations. The children's overall dietary intake was compared based on school lunch attendance. Mainland France. Schoolchildren aged 3-17 years (n 1068). Lunchtime food intake differed between the school canteen and other locations. Some intakes at school canteens were more in accordance with the regulations (more fruit and vegetables, fish and dairy products, and less sandwiches, soft drinks, chocolate and confectionery), whereas others highlighted needs for improvement (more sweet biscuits and pastries, ice cream and dairy desserts, pizzas and salty pastries). Many of these differences were also observed in the children's overall diet: children regularly attending school lunches ate more mashed fruit, fish and sweet biscuits or pastries, and less sandwiches and soft drinks. The link between school lunch attendance and overall diet was less pronounced in secondary-school children. School canteen attendance is associated with both potentially beneficial and deleterious differences in the lunchtime and overall diets of French children. These findings are important to consider when setting national regulations for school meal composition.

Consistent evidence exist on the harmful health effects of industrial trans fatty acids (TFA). In order to have accurate data on TFA intake and implement adequate measures to reduce their intake, each country should have updated estimates of TFA content in the diet. The objective of the present study was to provide data on the TFA content in food commercialized in the Portuguese market. The results on the TFA content of 268 samples acquired between October and December 2013 are reported. Samples were categorized as margarines and shortenings (n = 16), spreadable chocolate fats (n = 6), fried potatoes and chips (n = 25), industrial bakery (n = 4), breakfast cereals (n = 3), pastry products (n = 120), seasonings (n = 5), instant soups (n = 5), instant desserts (n = 6), chocolate snacks (n = 4), microwave popcorn (n = 4), cookies, biscuits and wafers (n = 53), and fast-food (n = 13), with butter (n = 4) included for comparison purposes. TFA were quantified by gas chromatography. Total TFA content in the fat ranged from 0.06% to 30.2% (average 1.9%), with the highest average values in the "biscuits, wafers and cookies" group (3.4% TFA), followed by the pastry group (2.0%). Fifty samples (19%) had TFA superior to 2% in the fat. These findings highlight there is still much need for improvement in terms of the TFA content in Portuguese foods, particularly in traditional pastry.

Nutrition is a factor influencing physical and mental fitness. In this study we examine the lifestyle of university students and its impact on nutritional errors. To evaluate the dietary behaviours of students taking into account gender and nutritional knowledge. Using a QEB questionnaire, we were able to evaluate dietary behaviours and nutritional knowledge of respondents. Our analysis was conducted on data obtained from 456 students. We found that nutritional knowledge for women was 34.7% satisfactory and 34.7% good. In contrast, nutritional knowledge for men varied, amounting to 40.2% satisfactory and 25.1% good. The number of meals and their regular consumption did not depend on gender or the nutritional knowledge of students, however, significant differences were recorded for the types of snacks they eat. A greater number of women than men snacked on sweets and biscuits, nuts and seeds, while in the case of salty snacks an opposite trend was observed. A higher level of nutritional knowledge correlated with the number of students snacking on fruit and vegetables instead of salty snacks. Moreover, it was observed that health-promoting behaviours such as not adding sugar to beverages and not adding salt to dishes were more common with women and individuals with a higher level of nutritional knowledge. Women more frequently snack on sweets, biscuits, nuts and seeds. More men snack on salty snacks, add sugar to beverages and add salt to dishes. Individuals with insufficient nutritional knowledge more frequently snack on salty snacks rather than fruit. Students with insufficient nutritional knowledge more often commit nutritional errors.

Thus, a survey of the thermal equipment in the mentioned industrial sector was made, followed of an evaluation of the technical possibilities of its incorporation in that sector, adaptations and the modifications of engineering projects, identifying the possibilities of productivity increase, improvement of quality and greater competitiveness, as well as the reduction of atmospheric emissions. So, It has been proposed solutions as the decentralized use of the thermal energy, recovery of heat of exhaustion gases, optimization of the thermal insulation, reduction of thermal inertia and the automatization of the control of the combustion in ovens and/or driers of the mentioned sectors. The main results of this study are: the possibility of reduction of, 32 to 37% in the consumption of thermal energy in the ovens of biscuit production, of 12 to 15% in the toasting of coffee and 20 to 30% in the processes of noodles production. Saving of around 25% would be expected in the small bearing ovens for baking. (author)

To examine changes in the food choices of New Zealand (NZ) adults, between the 1997 National Nutrition Survey (NNS97) and the 2008/09 NZ Adult Nutrition Survey (2008/09 NZANS). The 2008/09 NZANS and the NNS97 were cross-sectional surveys of NZ adults (aged 15 years and over). Dietary intake data were collected using a computer-based 24 h diet recall. Logistic regression models were used to examine changes over time in the percentage reporting each food group, with survey year, sex and age group (19-30 years, 31-50 years, 51-70 years, ≥71 years) as the variables. NZ households. Adults aged 19 years and over (NNS97, n 4339; 2008/09 NZANS, n 3995). In the 2008/09 NZANS compared with NNS97, males and females were less likely to report consuming bread, potatoes, beef, vegetables, breakfast cereal, milk, cheese, butter, pies, biscuits, cakes and puddings, and sugar/confectionery (all Psnacks and snack bars (e.g., crisps, extruded snacks, muesli bars; P=0.007) and pasta and pasta dishes (P=0.017). Although food choices were associated with sex and age group, there were few differential changes between the surveys by sex or age group. For all age groups there was a shift in the percentage who reported consuming the traditional NZ foods, namely bread, beef, potatoes and vegetables, towards more rice and rice dishes. Declines in the consumption of butter, pies, biscuits, cakes and puddings are congruent with current dietary guidelines.

Over 200 hybrid yeast strains were screened and 11 of these found to have versatile fermentation characteristics. This paper reports the results obtained with these 11 strains compared with a commercially available strain of baker's yeast used for bread making and marketed as 'instant active dry yeast'. In contrast to bakers yeast, the hybrid strains fermented very well in yeast, hard biscuit, shortcake and heavy cake dough without prior sponge formation. The fermentation kinetics were investigated and the technical potential of such hybrid strains discussed on the basis of the fermentation kinetics.

The effect of fruit paste additives on amino acid composition of farinaceous and decorative confectionery semifinished products was studied to decrease their fuel value. It was found that a partial replacement of sugar and fat for apple and quince pastes in apple biscuit and apple shortbread semiproducts led to an increase in the content of essential and sulfur-containing amino acids. Cream prepared from egg albumin and quince paste had reduced content of amino acids (except for glutamic acid) due to the diminished content of egg albumin, however, the balance of amino acid composition was improved.

2014-01-01

OBJECTIVE: To minimise the intake of industrial artificial trans fat (I-TF), nearly all European countries rely on food producers to voluntarily reduce the I-TF content in food. The objective of this study was to investigate the effect of this strategy on I-TF content in prepackaged biscuits...... countries in Europe still consume I-TF in amounts that increase their risk of coronary heart disease. Under current European Union (EU) legislation, the sale of products containing I-TF is legal but conflicts with the WHO recommendation to minimise the intake of I-TF. An EU-legislative limit on I-TF content...

Food fortification is a viable strategy to improve the nutritional status of populations. In Southeast Asia, recent growth and consolidation of the food industry provides an opportunity to explore whether certain widely consumed processed foods could contribute to micronutrient status if they are made with adequately fortified staples and condiments. To estimate the potential contribution certain processed foods can make to micronutrient intake in Southeast Asia if they are made with fortified staples and condiments; e.g., via the inclusion of iodized salt in various processed foods in the Philippines, fortified wheat flour in instant noodles in Indonesia, and fortified vegetable oil in biscuits in Vietnam. For Indonesia, the Philippines, and Vietnam, a review of consumption trends, relevant policies, and industry practices was conducted using publicly available sources,food industry market data and research reports, and oral communication. These informed the estimates of the proportion of the Recommended Nutrient Intake (RNI) that could be delivered via select processed foods. In the Philippines, Indonesia, and Vietnam, the processed food industry is not always required to use fortified staples and condiments. In the Philippines, dried salted fish with iodized salt would provide 64% to 85% of the iodine RNI for women of reproductive age and 107% to 141% of the iodine RNI for children 1 to 6 years of age. In Indonesia, a 75-g pack of instant noodles (a highly consumed product) with fortified wheat flour would provide 45% to 51% of the iron RNI for children 4 to 6 years of age and 10% to 11% of the iron RNI for women of reproductive age. In Vietnam, biscuits containing vegetable oil are increasingly popular. One 35-g biscuit serving with fortified vegetable oil would provide 13% to 18% of the vitamin A RNI for children 4 to 6 years of age and 12% to 17% of the vitamin A RNI for women of reproductive age.

Full Text Available Efficient design of multi-component food products containing dry and wet components such as biscuits with a moist fruit filling, is of growing interests for food industry. Technology is needed to prevent or reduce water migration from the moist filling to the dry porous cereal material. This can be done by using moisture barrier systems. Knowledge of the microstructure and its relation to water mobility is necessary to develop stable products. This paper describes a study that uses X-ray microtomography (μCT for the characterisation and visualisation of the 3-D structure of crackers with different porosity, coated biscuit shells and soup inclusions. μCT was used for imaging the inner cellular structure of the cereal matrix or to analyse the integrity of moisture barriers applied on the cereal product. 3-D image analysis methods were developed to obtain quantitative information about the cellular matrix which can be used as input for simulation models for moisture migration. The developed 3-D image analysis method maps the open cellular structure onto a network (graph representation in which the nodes correspond to the pores and the vertices to the pore-topore interconnection. The pores (nodes have properties such as volume, surface area and location whereas the vertices have properties such as direct (open connection and indirect (separated by a single lamella area. To check the segmentation and network description a model for pore to pore resistance was used. The obtained results demonstrate the potential of μCT and 3-D image analysis for extracting structural information which can be used in models for the moisture penetration in a cellular bakery product.

The benefits of whole grain consumption have been studied in human subjects, but little research exists on their effects in dogs. The objective of the present study was to test the effects of resistant starch (RS) in the diet of healthy adult dogs. Twelve adult Miniature Schnauzer dogs (eight males, four females; mean age: 3·3 (1·6) years; mean body weight: 8·4 (1·2) kg; mean body condition score: D/ideal) were randomly allotted to one of three treatment groups, which consisted of different amounts of RS supplied in a biscuit format. Dogs received either 0, 10 or 20 g biscuits per d (estimated to be 0, 2·5 or 5 g RS per d) that were fed within their daily energetic allowance. A balanced Latin square design was used, with each treatment period lasting 21 d (days 0-17 adaptation; days 18-21 fresh and total faecal collection). All dogs were fed the same diet to maintain body weight throughout the study. Dogs fed 5 g RS per d had lower (P = 0·03) fat digestibility than dogs fed 0 gRS per d, but DM, organic matter and crude protein digestibilities were not affected. Faecal fermentative end-products, including SCFA and branched-chain fatty acids, ammonia, phenols and indoles, and microbial populations were not affected. The minor changes observed in the present study suggest the RS doses provided to the dogs were too low. Further work is required to assess the dose of RS required to affect gut health.

We synthesized 26Al-containing acidic and basic (alkaline) sodium aluminum phosphates (SALPs) which are FDA-approved leavening and emulsifying agents, respectively, and used them to determine the oral bioavailability of aluminum incorporated in selected foods. We selected applicable methods from published syntheses (patents) and scaled them down (∼3000- and 850-fold) to prepare ∼300-400 mg of each SALP. The 26Al was incorporated at the beginning of the syntheses to maximize 26Al and 27Al equilibration and incorporate the 26Al in the naturally-occurring Al-containing chemical species of the products. Near infrared spectroscopy (NIR) and X-ray powder diffraction (XRD) were used to characterize the two SALP samples and some intermediate samples. Multi-elemental analysis (MEA) was used to determine Na, Al and P content. Commercial products were included for comparison. Satisfactory XRD analyses, near infrared spectra and MEA results confirmed that we synthesized acidic and basic SALP, as well as some of the syntheses intermediates. The 26Al-containing acidic and basic SALPs were incorporated into a biscuit material and a processed cheese, respectively. These were used in oral bioavailability studies conducted in rats in which the 26Al present in blood after its oral absorption was quantified by accelerator mass spectrometry. The results showed oral Al bioavailability from acidic SALP in biscuit was ∼0.02% and from basic SALP in cheese ∼0.05%, lower than our previous determination of Al bioavailability from drinking water, ∼0.3%. Both food and water can appreciably contribute to the Al absorbed from typical human Al intake.

Full Text Available Abstract Background Vascular dysfunction can develop from consumption of an energy-rich diet, even prior to the onset of obesity. However, the roles played by different dietary components remain uncertain. While attempting to develop models of obesity in a separate study, we observed that two high-energy diets of differing macronutrient compositions affected vascular function differently in overweight rats. Methods Male Wistar rats (n = 6/group were fed diets providing varying percentages of energy from fat and carbohydrate (CHO. For 10 weeks, they were fed either chow, as control diet (10% of energy from fat; 63% from CHO, chow supplemented with chocolate biscuit (30% fat; 56% CHO or a high-fat diet (45% fat; 35% CHO. Blood concentrations of biochemical markers of obesity were measured, and epididymal fat pads weighed as a measure of adiposity. Mesenteric arteries were dissected and their contractile and relaxant properties analysed myographically. Data were tested by analysis of variance (ANOVA. Results Weight gain and plasma concentrations of glucose, insulin and leptin were similar in all groups. However, biscuit-fed animals showed increased food intake (+27%; p p p p p Conclusion Vascular dysfunction resulting from consumption of a high-fat or combined relatively high-fat/high-CHO diet occurs through different physiological processes, which may be attributable to their differing macronutrient compositions. Combining potentially atherogenic macronutrients induces more extensive vascular impairment than that of high-fat alone, and may be attributable to the more marked dyslipidaemia observed with such a diet. Thus, these findings help clarify the role of dietary components in vascular impairment, which has implications for clinical approaches to preventing cardiovascular disease.

Undernutrition in infants and young children is a global health priority while overweight is an emerging issue. Small-scale studies in low- and middle-income countries have demonstrated consumption of sugary and savoury snack foods and soft drinks by young children. We assessed the proportion of children 6-23 months of age consuming sugary snack foods in 18 countries in Asia and Africa using data from selected Demographic and Health Surveys and household expenditures on soft drinks and biscuits using data from four Living Standards Measurement Studies (LSMS). Consumption of sugary snack foods increased with the child's age and household wealth, and was generally higher in urban vs. rural areas. In one-third of countries, >20% of infants 6-8 months consumed sugary snacks. Up to 75% of Asian children and 46% of African children consumed these foods in the second year of life. The proportion of children consuming sugary snack foods was generally higher than the proportion consuming fortified infant cereals, eggs or fruit. Household per capita daily expenditures on soft drinks ranged from $0.03 to $0.11 in three countries for which LSMS data were available, and from $0.01 to $0.04 on biscuits in two LSMS. Future surveys should include quantitative data on the purchase and consumption of snack foods by infants and young children, using consistent definitions and methods for identifying and categorising snack foods across surveys. Researchers should assess associations between snack food consumption and stunting and overweight, and characterise household, maternal and child characteristics associated with snack food consumption. © 2014 The Authors.

We used in this study Compton suppression method and epithermal neutron activation analysis to determine the concentration of nutrients and heavy metals in Nigerian food and beverages. The work was performed at the University of Texas TRIGA Reactor by short, medium, and long irradiation protocols, using thermal flux of 1.4x10 12 n cm -2 s -1 and epithermal flux of 1.4x10 11 n cm -2 s -1 . Application of Compton suppression method has reduced interferences from Compton scattered photons thereby allowing easy evaluation of Na, Cl, Ca, Cu, Mn, Mg, Co, Cr, Rb, Fe, and Se. The epithermal NAA method has enabled determination of Cd, As, Ba, Sr, Br, I, and V with little turn-around time. Quality Control and Quality Assurance of the method was tested by analyzing four Standard Reference Materials (non-fat powdered milk, apple leaves, citrus leaves, and peach leaves) obtained from National Institute for Standards and Technology. Our results show that sorghum, millet, and maize have high values of Zn, Mn, Fe, low values of Cd, As, and Se. Powdered milks, rice, beans, and soybeans were found to have moderate amounts of all the elements. Tobacco recorded high content of Cd, Mn, and As, whereas tea, tsobo leaves, Baobab leaves, and okro seed have more As values than others. However, biscuits, macaroni, spaghetti, and noodles show lower concentrations of all the elements. The distribution of these nutrients and heavy metals in these food and beverages shows the need to fortify biscuits and pastas with micro and macro-nutrients and reduce the use of tobacco, tea, tsobo leaves, Baobab leaves, and Okro seed to avoid intake of heavy elements.

The microaerophilic microbiota of de-novo paediatric inflammatory bowel disease: the BISCUIT study.

Directory of Open Access Journals (Sweden)

Richard Hansen

Full Text Available Children presenting for the first time with inflammatory bowel disease (IBD offer a unique opportunity to study aetiological agents before the confounders of treatment. Microaerophilic bacteria can exploit the ecological niche of the intestinal epithelium; Helicobacter and Campylobacter are previously implicated in IBD pathogenesis. We set out to study these and other microaerophilic bacteria in de-novo paediatric IBD.100 children undergoing colonoscopy were recruited including 44 treatment naïve de-novo IBD patients and 42 with normal colons. Colonic biopsies were subjected to microaerophilic culture with Gram-negative isolates then identified by sequencing. Biopsies were also PCR screened for the specific microaerophilic bacterial groups: Helicobacteraceae, Campylobacteraceae and Sutterella wadsworthensis.129 Gram-negative microaerophilic bacterial isolates were identified from 10 genera.

To determine the trans fatty acids content of processed foods frequently consumed by adults living in a Rio de Janeiro, Brazil, after the enactment of a mandatory trans fatty acids labelling policy. Between February 2014 and January 2015, a specifically dietary questionnaire was completed by 107 adults to assess the frequency of processed foods consumption. The most commonly consumed products from the survey, including vegetable oils, margarine, biscuits, snacks, cheese bread (pão de queijo), french fries, cheeseburger and ice cream, were then analyzed for their trans fatty acids content using gas chromatography with a flame ionization detector. Differences in the levels of trans fatty acids were observed among 22 products analyzed, considering that trans fatty acids content ranged between 0.0 g/100 g in samples of cream cracker biscuit 1 and olive oil to 0.83 g/100 g in samples of cheeseburger (fast food), 0.51 g/100 g in samples of frozen pão de queijo and 12.92 g/100 g in samples of chocolate sandwich cookies with cream filling 2. The overall trans fatty acids content of the different samples of margarine brands was 0.20 g/100 g for brand 1 and 0.0 g/100 g for brand 2. These data are significantly lower than those observed in a survey conducted in 2003, when the regulation had been enacted. Our data indicate that Brazilian regulation is very likely implicated in the observed drop in trans fatty acids of the most processed foods but has yet to eliminate them, which reinforces the urgent need to revise the legislation, since a minimum amount of trans fat does not mean that the food product does not contain this type of fat.

Nutrition education messages should take into account the food habits of those who are to be educated. These can be revealed by computer analysis of weighed intake data, which has been collected for calculation of nutrient intakes. Seventy-six students and staff at Robert Gordon's Institute of Technology weighed their food for 1 week and the records were used to determine the frequency of consumption of foods and portion sizes, as well as nutrient intakes. There were only very minor relationships between the number of different foods chosen and nutritional variables. Nutrition students had successfully changed the frequency of consumption of certain foods relative to others and as a result consumed diets containing a lower proportion of energy from fat. Messages to non-nutrition students might profitably incorporate those beneficial changes that nutrition students had easily accomplished. This study revealed that certain (otherwise common and nutritionally unsound) food choices were not a major part of the subjects' habits, and could be given low priority in educational messages. It was suggested that foods exhibiting high variability of portion weight might be under greater individual control and hence more amenable to change. A study of the distribution of portion weights reveals information about number of slices, biscuits, etc, taken in each portion. This varied for different kinds of biscuit. It was concluded that messages should target specific foods rather than stress variation in the diet. It is suggested that educators should consider whether messages would be more effective in terms of frequency of consumption or size of portion for particular groups. The meal distribution pattern also shows which foods are most commonly consumed at home or in the canteen, hence whether education might be best directed to the individual or the caterer, respectively.

We used in this study Compton suppression method and epithermal neutron activation analysis to determine the concentration of nutrients and heavy metals in Nigerian food and beverages. The work was performed at the University of Texas TRIGA Reactor by short, medium, and long irradiation protocols, using thermal flux of 1.4x10{sup 12} n cm{sup -2} s{sup -1} and epithermal flux of 1.4x10{sup 11} n cm{sup -2} s{sup -1}. Application of Compton suppression method has reduced interferences from Compton scattered photons thereby allowing easy evaluation of Na, Cl, Ca, Cu, Mn, Mg, Co, Cr, Rb, Fe, and Se. The epithermal NAA method has enabled determination of Cd, As, Ba, Sr, Br, I, and V with little turn-around time. Quality Control and Quality Assurance of the method was tested by analyzing four Standard Reference Materials (non-fat powdered milk, apple leaves, citrus leaves, and peach leaves) obtained from National Institute for Standards and Technology. Our results show that sorghum, millet, and maize have high values of Zn, Mn, Fe, low values of Cd, As, and Se. Powdered milks, rice, beans, and soybeans were found to have moderate amounts of all the elements. Tobacco recorded high content of Cd, Mn, and As, whereas tea, tsobo leaves, Baobab leaves, and okro seed have more As values than others. However, biscuits, macaroni, spaghetti, and noodles show lower concentrations of all the elements. The distribution of these nutrients and heavy metals in these food and beverages shows the need to fortify biscuits and pastas with micro and macro-nutrients and reduce the use of tobacco, tea, tsobo leaves, Baobab leaves, and Okro seed to avoid intake of heavy elements.

This study investigated the preference and intake frequency of a list of 15 commonly available high sodium Malaysian foods/dishes, discretionary salt use, and their possible association with demographics, blood pressures and anthropometric measurements among 300 Malaysian university students (114 males, 186 females; 259 ethnic Chinese, 41 Indians; 220 lean, 80 overweight). French fries and instant soup noodle were found to be the most preferred and most frequently consumed salty food, respectively, while salted fish was least preferred and least frequently consumed. Males had a significantly higher intake frequency of at least 6 of the salty foods, but the preference of most salty foods was not significantly different between genders. Ethnic Chinese significantly preferred more and took more frequently traditional and conventional Malaysian foods like asam laksa (a Malaysian salty-sour-spicy noodle in fish stock), salted biscuits and salted vegetable, while Indians have more affinity and frequency towards eating salty Western foods. Body Mass Index was significantly negatively correlated with the intake frequency of canned/packet soup and salted fish while waist circumference was significantly positively correlated with the preference of instant noodle. Also, an increased preference of potato chips and intake frequency of salted biscuits seemed to lead to a decreased WHR. Other than these, all the other overweight/obesity indicators did not seem to fully correlate with the salty food preference and intake frequency. Nevertheless, the preference and intake frequency of asam laksa seemed to be significant negative predictors for blood pressures. Finally, increased preference and intake frequency of high sodium shrimp paste (belacan)-based foods like asam laksa and belacan fried rice seemed to discourage discretionary salt use. In conclusion, the preference and intake frequency of the high sodium belacan-based dish asam laksa seems to be a good predictor for ethnic

Full Text Available In this global era where the level of competition is higher, in addition to the influence of the suitable marketing strategy is also required strategy from the side of production/productivity. PT. XYZ is a company engaged in the manufacturing of snacks especially biscuits. The problem that often occurs in this company is the number of biscuits that are not in accordance with the standard and the production does not reach the target set because the machine suddenly breaks down frequently. To overcome the problems PT. XYZ then choose to implement the Total Productive Maintenance (TPM strategy. This study aims to evaluate the implementation of 8 TPM Pillars and measure the effects on manufacturing performance in the form of Overall Equipment Effectiveness (OEE and Waste. This study uses questionnaire-based survey method. The number of samples distributed is 40 units. Which returned and filled 33 questionnaires and which is worth to be processed as many as 30 samples. Then tested the validity and reliability of data using SPSS program. Validity critical value R = 0.361 for n = 30 and error rate 5%. For reliability test, R value = 0.60 was selected. From the validity test, there are 7 items of questions that are not valid so it is not included in the next process. For the reliability test of the questionnaire is quite reliable with the value of Cronbach's alpha of 0.811. From the CFA analysis, only 6 of 8 TPM pillars are significant while for manufacturing performance only OEE variable is significant. Correlation between 8 Pillars of TPM and manufacturing performance is Strong enough with a value of R = 0.862, which also means 74.3% (R2 variable manufacturing performance can be explained/influenced by variable 8 Pillar TPM and 26.7% the rest by other variables.

Although both consumption of ultra-processed products and asthma are common during adolescence, the epidemiological evidence in regarding their association is unclear. We investigated the associations of ultra-processed products consumption with asthma and wheezing in a representative sample of Brazilian adolescents. We used data from a representative sample of 109,104 Brazilian adolescents enrolled in the National Survey of School Health, 2012. The consumption of ultra-processed products was based on the weekly consumption (0-2, 3-4, ≥5 days/week) of sweet biscuits, salty biscuits, ultra-processed meats, sweets/candies, soft drinks, and packaged snacks over the previous seven days. We also calculated an ultra-processed consumption score by adding partial scores corresponding to weekly frequency intake of each ultra-processed product. The ultra-processed consumption score ranged from 0 to 42, the higher score, the higher the intake of these products. Presence of wheezing in the previous 12 months and asthma at any time in the past were self-reported. The adjusted odds ratios of asthma comparing the extreme categories ranged from 1.08 (95% CI 1.03-1.13) for sweets/candies to 1.30 (1.21-1.40) for ultra-processed meats. Similar magnitude of associations was found for wheezing outcome. The ultra-processed consumption score was positively associated with presence of asthma and wheezing in a dose-response manner. The adjusted OR of asthma and wheezing comparing highest to lowest quintile of ultra-processed consumption score were 1.27 (95% CI 1.15-1.41) and 1.42 (1.35-1.50), respectively. The consumption of ultra-processed products was positively associated with the presence of asthma and wheezing in adolescents. This article is protected by copyright. All rights reserved.

'Ultra-processed foods' (UPF) have been industrially processed and tend to be higher in saturated fat, sodium and sugar than other foods. There is some evidence that consumption of UPF is associated with overweight, obesity and related diseases. In developed countries more than half of dietary energy is attributed to UPF. One reason for reliance on UPF may be poor home food preparation skills or infrequent use of these. This relationship has been previously proposed but not tested. We examined the relationship between home food preparation skills and behaviour and consumption of UPF. We used data from adults in the UK National Diet & Nutrition Survey 2008-09. Home food preparation skills and behaviours of adults (n = 509) were assessed using questions on confidence using eight cooking techniques, confidence cooking 10 foods, ability to prepare a cake or biscuits without help, and whether or not participants prepared a main meal five or more days per week. Individuals' UPF consumption was determined from four-day estimated diet diaries. Associations were adjusted for age, gender, occupational social class and household composition. In fully adjusted models, individuals who were confident with all 10 foods (adjusted beta (95% CI) = -3.76 (-6.02 to -1.50)), able to bake cakes or biscuits without help (-3.87 (-6.62 to -1.12)), and cooked a main meal at least five days a week (-2.84 (-5.43 to -0.24)) consumed a lower percentage of dietary energy from UPF. In UK adults better home food preparation skills and more frequent use of these skills tended to be cross-sectionally associated with lower UPF consumption. Greater encouragement of these skills may help reduce reliance on UPF.

Episodic response project: Wet deposition at watersheds in three regions of the eastern United States

International Nuclear Information System (INIS)

Barchet, W.R.

1991-11-01

During the period from August 1988 to June 1990, wet-only sampling of precipitation was carried out at three Episodic Response Project sites and at one supplemental site. The three watershed sites are Moss Lake, Biscuit Brook, and Linn Run. The supplemental site was the MAP3S site at Pennsylvania State University that characterizes the central group of northern Appalachian streams. The site operators adhered by varying degrees to the sample collection protocol based on the daily sampling protocol of the MAP3S Precipitation Chemistry Network. Sulfate and nitrate ion together accounted for more than 80% of total anions (in μEq/L) in the precipitation at all sites. Wet deposition of sulfate at Moss Lake, Biscuit Brook, Penn State, and Linn Run averaged 223, 230, 253, and 402 mg/m 2 /month, respectively, whereas nitrate wet deposition averaged 197, 195, 160, and 233 mg/m 2 /month, respectively. Sulfate deposition was a factor of 2 to 4 higher in summer than in winter. The seasonal pattern for nitrate deposition was weak; the seasonal contrast was less than a factor of 2.5 at all sites. The association between the wet deposition and precipitation chemistry at the MAP3S monitoring site and the average for the study watersheds was dependent on the distance between the site and watershed and the intervening terrain. Precipitation chemistry at the monitoring site is representative of that at the ERP study watersheds in the Adirondack and Catskill regions and in the south-western group of watersheds in the Appalachian region. High spatial variability in precipitation amounts makes this assumption weaker for wet deposition. Chemical input to watersheds from dry deposition has not been determined at any site but could range from a factor of 0.3 to 1.0 of the wet deposition. 7 refs., 38 figs., 12 tabs

A European inter-laboratory study was conducted to validate two analytical procedures for the determination of acrylamide in bakery ware (crispbreads, biscuits) and potato products (chips), within a concentration range from about 20 microg/kg to about 9000 microgg/kg. The methods are based on gas chromatography-mass spectrometry (GC-MS) of the derivatised analyte and on high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) of native acrylamide. Isotope dilution with isotopically labelled acrylamide was an integral part of both methods. The study was evaluated according to internationally accepted guidelines. The performance of the HPLC-MS/MS method was found to be superior to that of the GC-MS method and to be fit-for-the-purpose.

Malignant pleural mesothelioma in bakers and pastry cooks.

2001-10-01

The occurrence of malignant pleural mesothelioma (MPM) among bakers and pastry cooks has never been documented. We detected eight cases of MPM in bakers, pastry cooks, and biscuit cooks engaged in making, baking/cooking, and selling pastry/bread in two hospital-based series (Rome and Orbassano/Turin, Italy; period 1990-1997; 222 cases). Field-investigations revealed asbestos-containing material (ACM) in ovens for baking bread, that were manufactured prior to the 1980s. It is suggested that there is a possible new association of the risk of having worked as a baker or pastry cook and MPM. Presumptive source of exposure to asbestos was the use of asbestos-insulated ovens. Copyright 2001 Wiley-Liss, Inc.

The use of inductively coupled plasma mass spectrometry (ICP-MS) for the determination of toxic and essential elements in different types of food samples

Voica, C.; Dehelean, A.; Kovacs, M. H.

2012-02-01

Food is the primary source of essential elements for humans and it is an important source of exposure to toxic elements. In this context, levels of essential and toxic elements must be determined routinely in consumed food products. The content of trace elements (As, Pb, Cu, Cd, Zn, Sn, Hg) in different types of food samples (e.g. rice, bread, sugar, cheese, milk, butter, wheat, coffee, chocolate, biscuits pasta, etc.) was determined, using inductively coupled plasma mass spectrometry (ICP-MS). Trace element contents in some foods were higher than maximum permissible levels of toxic metals in human food (Cd in bread, Zn in cheese, Cu in coffee, Hg in carrots and peppers).

A study was conducted to evaluate the use of industrial microwaves and their environmental benefits in the Los Angeles Basin. The objective of the project was to assess the use of radio frequency (RF) post baking dryers to reduce the emissions per pound of output from a biscuit manufacturer and to determine the net savings in fuel consumed. Emissions measurements and energy consumption measurements were made prior to modifications to have a baseline for data for comparison. Results showed that the bakery used 17% less fuel and productivity increased by 25% after installation of the RF units. It was estimated that NOx emissions would be reduced 15-20%. The addition of RF post baking dryers provided a significant reduction in the emission problem in Los Angeles. 1 fig.

Vegetation recovery after fire in the Klamath-Siskiyou region, southern Oregon

Science.gov (United States)

Hibbs, David; Jacobs, Ruth

2011-01-01

In July 2002, lightning strikes started five forest fires that merged into one massive wildfire in the Klamath-Siskiyou Ecoregion of southern Oregon. Aided by drought, severe weather conditions, dry fuels, and steep topography, the fire grew to more than 200,000 hectares of mostly public forest land. Known as the Biscuit Fire, it was Oregon's largest forest fire in more than 130 years and one of the largest wildfires on record in the United States. Discussions centered around why such a massive fire was happening, how large would it become, who was keeping communities and homes safe, and what would be the final economic and ecological outcome. Weeks later when the fire was out, conversations turned to other questions, including what, if anything, should happen for forest recovery.

Parental concerns related to communication are an oft-cited reason that children present to early intervention clinics. We examine the relationship between early communication first concerns (FCs) and symptoms of ASD. The present study included 3173 toddlers at risk for developmental delay. The Battelle Developmental Inventory, 2nd edition and the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) were used to examine developmental quotient scores and autism symptoms. Significant results were observed with respect to FC group and gender. A significant effect of FC-Communication group was observed with respect to developmental quotient overall and subscale scores, as well as autism symptom scores. Those with communication disorders are a heterogeneous population and do not account for all children who will meet criteria for a diagnosis of an ASD.

Trials have principally turned on a glandless cottonseed flour, with 56 p. 100 of proteins. It is possible to blend it with millet or sorghum flour, and so to prepare the main meals of the local cooking. Trial of acceptability and long-dated consumption have shown that this flour is rather well appreciated especially in sauces. The growth of young children has been better thanks to the consumption of a cottonseed flour pap during six months. Trials to manufacture biscuits and noodles have been attempted. Kernels of cottonseed with 32 p. 100 of proteins and 33 p. 100 of lipids have been consumed with success. Four tons of kernels have been sold at the same price as sorghum in the area where the glandless cotton plant is under cultivation.

Cyclone trends constrain monsoon variability during late Oligocene sea level highstands (Kachchh Basin, NW India)

Climate change has an unknown impact on tropical cyclones and the Asian monsoon. Herein we present a sequence of fossil shell beds from the shallow-marine Maniyara Fort Formation (Kachcch Basin) as a recorder of tropical cyclone activity along the NW Indian coast during the late Oligocene warming period (~ 27-24 Ma). Proxy data providing information about the atmospheric circulation dynamics over the Indian subcontinent at this time are important since it corresponds to a major climate reorganization in Asia that ends up with the establishment of the modern Asian monsoon system at the Oligocene-Miocene boundary. The vast shell concentrations are comprised of a mixture of parautochthonous and allochthonous assemblages indicating storm-generated sediment transport from deeper to shallow water during third-order sea level highstands. Three distinct skeletal assemblages were distinguished, each recording a relative storm wave base. (1) A shallow storm wave base is shown by nearshore molluscs, reef corals and Clypeaster echinoids; (2) an intermediate storm wave base depth is indicated by lepidocyclinid foraminifers, Eupatagus echinoids and corallinacean algae; and (3) a deep storm wave base is represented by an Amussiopecten bivalve-Schizaster echinoid assemblage. These wave base depth estimates were used for the reconstruction of long-term tropical storm intensity during the late Oligocene. The development and intensification of cyclones over the recent Arabian Sea is primarily limited by the atmospheric monsoon circulation and strength of the associated vertical wind shear. Therefore, since the topographic boundary conditions for the Indian monsoon already existed in the late Oligocene, the reconstructed long-term cyclone trends were interpreted to reflect monsoon variability during the initiation of the Asian monsoon system. Our results imply an active monsoon over the Eastern Tethys at ~ 26 Ma followed by a period of monsoon weakening during the peak of the late

Following a qualitative and quantitative analysis of the main data, two types of models were experimented allowing to 'project' exchange tables in a near future: 'empirical' models derived from a systematic study of the various coefficients able to specify the structure of an exchange matrix; 'explanatory' models based on the utilization of a linear model and the construction of a 'generalized cost' of exchange with the help of physical and economical parameters. The contamination model is then presented; it gives and forecasts individual and collective doses likely to be received by the inhabitants of each region from the ingestion of bread, biscuits... The doses are dependent on the results or assumptions at the level of the initial contaminations, the technical transformations of the product and the inter-regional exchanges of the initial product and its derivatives [fr

1998-01-01

A technique for development of potato flour was standardized. Five products viz. cake, biscuit, weaning food, panjiri and ladoo were prepared incorporating potato flour, defatted soy flour and corn flour. Baking and roasting were the major processing techniques employed for the development of these products. Protein, ash and fat contents of potato flour were almost similar to those of raw potatoes. Significant differences in protein, ash and fat contents of all the products were observed. Protein and starch digestibility of potato flour was significantly higher than that of raw potatoes. Protein digestibility increased by 12 to 17 percent on baking or roasting of products. Processed products had significantly higher starch digestibility and mineral availability compared to raw products. Thus, it can be concluded that roasting and baking are effective means of improving starch and protein digestibility and mineral availability of products.

Paradoxes of traditional industrial work in knowledge society

DEFF Research Database (Denmark)

Holt, Helle; Hvid, Helge Søndergaard; Kamp, Annette

Traditional industry, where work is repetitive and submitted to a comprehensive machine system, did not disappear with the rise of ‘knowledge society’, not even in the developed western societies.An illustrative case is the Danish food industry, which employed 85,353 in 1997and 65,842 in 2008. Even...... though the number of employees has been falling, the food industry is still a significant sector in the relatively small Danish labour market. However, traditional industry is marked by the principles of work organizations supposed to belong to ‘knowledge society’: functional flexibility, flexibility...... of time, team organisation, project organisation, and value management. The way working conditions are influenced by these new principles of organisations was studied in two case factories. The two factories, one producing biscuits and the other producing sweets, have similar production systems. Both...

Full Text Available The National Authority for Consumers’ Protection is concerned to survey the market of agro-alimentary produce; as a result of the punctual programme, it develops control activities in order to check quality / conformity of foodstuff supplied for sale. Meat preparations are the most demanded and preferred; this is why they have paid particular attention to quality, labelling, marketing, and storage. Of the total 87 complaints concerning lack of compliance with the standards of such items as fruits, milk, meat, vegetables, bread and bakery, alcoholic and non-alcoholic beverages, coffee, chocolate, and fish preparations, only 31 proved justified. We can see that of the total complaints only 35.63% are justified and that they concern such produce as biscuits, fresh and refrigerated fish, vegetable and fruit juices, pet foods, spirits, beer, and non-alcoholic beverages.

Tracing artificial trans fat in popular foods in Europe: a market basket investigation.

Science.gov (United States)

Stender, Steen; Astrup, Arne; Dyerberg, Jørn

2014-05-20

To minimise the intake of industrial artificial trans fat (I-TF), nearly all European countries rely on food producers to voluntarily reduce the I-TF content in food. The objective of this study was to investigate the effect of this strategy on I-TF content in prepackaged biscuits/cakes/wafers in 2012-2013 in 20 European countries. The I-TF content was assessed in a market basket investigation. Three large supermarkets were visited in each capital, and in some countries, three additional ethnic shops were included. A total of 598 samples of biscuits/cakes/wafers with 'partially hydrogenated vegetable fat' or a similar term high on the list of ingredients were analysed, 312 products had more than 2% of fat as I-TF, exceeding the legislatively determined I-TF limit in Austria and Denmark; the mean (SD) was 19 (7)%. In seven countries, no I-TF was found, whereas nine predominantly Eastern European countries had products with very high I-TF content, and the remaining four countries had intermediate levels. Of the five countries that were examined using the same procedure as in 2006, three had unchanged I-TF levels in 2013, and two had lower levels. The 18 small ethnic shops examined in six Western European countries sold 83 products. The mean (SD) was 23 (12)% of the fat as I-TF, all imported from countries in Balkan. In Sweden, this type of food imported from Balkan was also available in large supermarkets. The findings suggest that subgroups of the population in many countries in Europe still consume I-TF in amounts that increase their risk of coronary heart disease. Under current European Union (EU) legislation, the sale of products containing I-TF is legal but conflicts with the WHO recommendation to minimise the intake of I-TF. An EU-legislative limit on I-TF content in foods is expected to be an effective strategy to achieve this goal. Published by the BMJ Publishing Group Limited.

Padma Ishwarya, S; Prabhasankar, P

2014-01-01

The concept of functional foods has markedly moved toward gastrointestinal health. The prebiotic approach aims at achieving favorable milieu in the human gut by stimulating beneficial bacteria. Several food products act as substrates for the application of prebiotic substances and bakery products are one such category. The trend of increasing consumption of bakery products justifies the choice of using them as vehicles for delivering the prebiotic compounds. Apart from the health benefits, the prebiotic compounds also have nutritional and technological effects in the food matrix. In addition to increasing the fiber content, the candidate prebiotics also affect the rheology and final quality of bakery products. The prebiotic compounds are selected accordingly to confer desirable properties in the final product. The health advantages of prebiotics being well established, the technological advantages in bakery products such as bread and biscuits and extruded product such as pasta are discussed elaborately.

As with human beings, dogs suffer from the consequences of cancer. We investigated the potential of a formulation comprised of resveratrol, ellagic acid, genistein, curcumin and quercetin to modulate biomarkers indicative of disease prevention. Dog biscuits were evaluated for palatability and ability to deliver the chemopreventive agents. The extent of endogenous DNA damage in peripheral blood lymphocytes from dogs given the dietary supplement or placebo showed no change. However, H2O2-inducible DNA damage was significantly decreased after consumption of the supplement. The expression of 11 of 84 genes related to oxidative stress was altered. Hematological parameters remained in the reference range. The concept of chemoprevention for the explicit benefit of the canine is compelling since dogs are an important part of our culture. Our results establish a proof-of-principle and provide a framework for improving the health and well-being of "man's best friend".

Snack foods and dental caries. Investigations using laboratory animals.

Grenby, T H

1990-05-05

The nation's eating habits are undergoing major transformation, with a swing away from traditional meals to a huge increase in snack consumption, but very little is known of the nutritional and dental implications of this change. The research project reported here evaluated a range of snack foods in caries-active laboratory animals, comparing them, as dietary ingredients, with noncariogenic and cariogenic (sugar) diets. The findings showed the very low cariogenicity of salted peanuts, followed by ready-salted and salt and vinegar crisps, extruded maize, mixed-starch and prefabricated/fried potato products, and cheese-filled puffs. Other varieties of crisps (cheese and onion and special shapes) proved to be more cariogenic, not far short of semi-sweet biscuits in some cases. It is concluded that the severity of the processing undergone by the snack foods and the nature of the flavouring agents with which they are coated can influence their dental properties.

Consolidation treatments applied to ceramic tiles: are they homogeneous?

Costa, D.; Leal, A.S.; Mimoso, J.M; Pereira, S.M.R.

2017-01-01

The mass consolidation treatment of azulejos is necessary when ceramic biscuits show signs of disaggregation. Such treatment is often used as a complementary conservation technique to the reestablishment of weakened glaze-ceramic bonds. In this research, two commonly used consolidants (ethyl silicate and acrylic resin) were tested on artisanal ceramic tiles via mass consolidation and the resulting impregnation profiles were evaluated. The results indicated that after consolidation, hard zones frequently formed due to localized consolidant concentration after the polymerization and curing processes. These inhomogeneous hard zones subsequently influenced the results obtained through conventional mechanical strength testing (i.e. flexural and compression), creating a false impression of success. This research demonstrated that by using the Drilling Resistance Measuring System, impregnation characteristics such as penetration depth and distribution of consolidant could be observed that otherwise could not be discerned through the more common testing methods. As such, a more extensive evaluation of consolidation effects was achieved. [es

Innovative Vacuum Distillation for Magnesium Recycling

Zhu, Tianbai; Li, Naiyi; Mei, Xiaoming; Yu, Alfred; Shang, Shixiang

Magnesium recycling now becomes a very important subject as magnesium consumption increases fast around the world. All commonly used magnesium die-casting alloys can be recycled and recovered to the primary metal quality. The recycled materials may be comprised of biscuits, sprues, runners, flash, overflows, dross, sludge, scrap parts, and old parts that are returned from service, An innovative magnesium recycle method, vacuum distillation, is developed and proved out to be able to recycle magnesium scraps, especially machining chips, oily magnesium, smelting sludge, dross or the mixture. With this process at a specific temperature and environment condition, magnesium in scraps can be gasified and then solidified to become crystal magnesium crown. This `recycled' magnesium crown is collected and used as the raw material of magnesium alloys. The experimental results show the vacuum distillation is a feasible and plausible method to recycle magnesium. Further, the cost analysis will be addressed in this paper.

Negro, Emilse; González, Marcela Aída; Bernal, Claudio Adrián; Williner, María Rosa

2017-08-01

Studies have reported the relationship between the excessive intake of saturated fatty acids (SFA) and trans fatty acids (t-FA) and an increased risk of cardiovascular disease. Since 2006, the MERCOSUR countries require that the mandatory nutrition labeling should include information not only about the content of SFA but also about the content of t-FA. This does not apply to fractionated products at the point of retail, such as bakery products. This paper aimed to determine the total fat content and the fatty acid profile in unpackaged traditional bakery products (breads, biscuits and pastries) in Santa Fe, Argentina. Except for French bread, the contribution of t-FA and SFA to the total FA consumption from baked products was high. On the other hand, due to the high variability detected in the FA composition of bakery products between bakeries, it would be necessary to implement regulations making nutrition labeling mandatory in these products.

There are five major extant groups of Echinodermata: Crinoidea (feather stars and sea lillies), Ophiuroidea (brittle stars and basket stars), Asteroidea (sea stars), Echinoidea (sea urchins, sea biscuits, and sand dollars), and Holothuroidea (sea cucumbers). These animals are known for their pentaradial symmetry as adults, unique water vascular system, mutable collagenous tissues, and endoskeletons of high magnesium calcite. To our knowledge, the only echinoderm species with a genome sequence available to date is Strongylocentrotus pupuratus (Echinoidea). The availability of additional echinoderm genome sequences is crucial for understanding the biology of these animals. Here we present assembled draft genomes of the brittle star Ophionereis fasciata, the sea star Patiriella regularis, and the sea cucumber Australostichopus mollis from Illumina sequence data with coverages of 12.5x, 22.5x, and 21.4x, respectively. These data provide a resource for mining gene superfamilies, identifying non-coding RNAs, confirming gene losses, and designing experimental constructs. They will be important comparative resources for future genomic studies in echinoderms.

Full Text Available In this study, a 6-axis robotic arm, which was controlled by an embedded Raspberry Pi with onboard WiFi, was developed and fabricated. A mobile application (APP, designed for the purpose, was used to operate and monitor a robotic arm by means of a WiFi connection. A computer vision was used to read common one-dimensional barcode (EAN code for the handling and identification of products such as milk tea drinks, sodas and biscuits. The gripper on the end of the arm could sense the clamping force and allowed real-time control of the amount of force used to hold and handle the products. The packages were all made of different material and this control allowed them to be handled without danger of damage or deformation. The maximum handling torque used was ~1.08 Nm and the mechanical design allowed the force of the gripper to be uniformly applied to the sensor to ensure accurate measurement of the force.

In this work, graphene oxide was reduced to graphene with an endogenous reducing agent from dimethylformamide, and then AuPd alloy nanoparticles were electrodeposited on the graphene film. The obtained AuPd-graphene hybrid film was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction and voltammetry. The electrochemical behavior of vanillin was studied using the AuPd-graphene hybrid based electrode. It presented high electrocatalytic activity and vanillin could produce a sensitive oxidation peak at it. Under the optimal conditions, the peak current was linear to the concentration of vanillin in the ranges of 0.1-7 and 10-40 μM. The sensitivities were 1.60 and 0.170 mA mM(-1) cm(-2), respectively; the detection limit was 20 nM. The electrode was successfully applied to the detection of vanillin in vanilla bean, vanilla tea and biscuit samples. Copyright © 2013 Elsevier Ltd. All rights reserved.

A generic sample preparation method for the determination of acrylamide in foods was developed. The method entails extraction with methanol, purification with Carrez I and II solutions, evaporation and solvent change to water, and cleanup with Oasis HLB solid-phase extraction (SPE) cartridge. The final extract was analyzed by liquid chromatography-mass spectrometry (LC-MS) for quantitation. The chromatographic separation was performed on ODS-3 column using the isocratic mixture of 0.01 mM acetic acid in 0.2% aqueous solution of formic acid at a flow rate of 0.6 ml/min at 25 degrees C. The recoveries of acrylamide from potato chips, biscuits and coffee ranged between 92.8 and 101.5% with relative standard deviations of 4.1% or less. The limit of detection (LOD) and the limit of quantitation (LOQ) were 2 ng/g and 6 ng/g in the basis of signal to noise ratios of 3:1 and 9:1, respectively.

The goal of the present study was to quantify the rate and extent of polyphenols released in the gastrointestinal tract (GIT) from natural (NS) and blanched (BS) almond skins. A dynamic gastric model of digestion which provides a realistic simulation of the human stomach was used. In order to establish the effect of a food matrix on polyphenols bioaccessibility, NS and BS were either digested in water (WT) or incorporated into home-made biscuits (HB), crisp-bread (CB) and full-fat milk (FM). Phenolic acids were the most bioaccessible class (68.5% release from NS and 64.7% from BS). WT increased the release of flavan-3-ols (p digestion, whereas CB and HB were better vehicles for BS. FM lowered the % recovery of polyphenols, the free total phenols and the antioxidant status in the digestion medium, indicating that phenolic compounds could bind protein present in the food matrix. The release of bioactives from almond skins could explain the beneficial effects associated with almond consumption. PMID:27649239

The study involved 50 students of Wesley School 1 for the Deaf, Lagos (26 males and 24 females, aged 10-19 years, mean 13.3 +/- 2.8). Information about previous dental care, oral hygiene, and snacking habits were obtained through a questionnaire and sign language by the teachers. Only 12 percent of pupils had received dental care. Eight percent and 72 percent, respectively, gave correct answers to causes of tooth decay and bleeding gums. Ninety-four percent brushed their teeth once daily, with no significant sex difference (P > .05). Reported dental problems include bleeding gums (36%), tooth discoloration, and tooth decay. The majority of pupils (60%) preferred biscuits and soft drinks as snacks. More than 90 percent were willing to have a dental check-up. The oral health knowledge and practices of this group of children will improve through a controlled school-based oral health education program.

Selected commercial processed foods available in the Brazilian market (306 samples) were analysed for furan content using a validated gas chromatography-mass spectrometry method preceded by headspace solid phase micro-extraction (HS-SPME-GC/MS). Canned and jarred foods, including vegetable, meat, fruit and sweet products, showed levels up to 32.8 µg kg⁻¹, with the highest concentrations observed in vegetables and meats. For coffee, furan content ranged from 253.0 to 5021.4 µg kg⁻¹ in the roasted ground coffee and from not detected to 156.6 µg kg⁻¹ in the beverage. For sauces, levels up to 138.1 µg kg⁻¹ were found. In cereal-based products, the highest concentrations (up to 191.3 µg kg⁻¹) were observed in breakfast cereal (corn flakes), cracker (cream crackers) and biscuit (wafer). In general, these results are comparable with those reported in other countries and will be useful for a preliminary estimate of the furan dietary intake in Brazil.

Full Text Available The opportunity to supplement common cassava biscuits with a product of higher nutritional value meets consumer expectations. In this work it was studied the effects of process parameters and flaxseed addition on physical properties of expanded snacks. Extrusion process was carried out using a single screw extruder in a factorial central composite rotatable design with four factors: flaxseed flour percentage (0-20%, moisture (12-20%, extrusion temperature (90-130 °C and screw speed (190-270. The effect of extrusion variables was investigated in terms of expansion index, specific volume, water absorption index, water solubility index, color parameters (L*, a* ,b* and hardness. The data analysis showed that variable parameters of the extrusion process and flaxseed flour affected physical properties of puffed snacks. Among the experimental conditions used in the present study, expanded snack products with good physical properties can be obtained under the conditions of 10% flaxseed flour, 230 rpm screw speed, temperature of 90 °C and moisture of 12%.

The present study arose from the need to determine inorganic arsenic (iAs) at low levels in cereal-based food. Validated methods with a low limit of detection (LOD) are required to analyse these kinds of food. An analytical method for the determination of iAs, methylarsonic acid (MA) and dimethylarsinic acid (DMA) in cereal-based food and infant cereals is reported. The method was optimised and validated to achieve low LODs. Ion chromatography-inductively coupled plasma mass spectrometry (IC-ICPMS) was used for arsenic speciation. The main quality parameters were established. To expand the applicability of the method, different cereal products were analysed: bread, biscuits, breakfast cereals, wheat flour, corn snacks, pasta and infant cereals. The total and inorganic arsenic content of 29 cereal-based food samples ranged between 3.7-35.6 and 3.1-26.0 μg As kg(-1), respectively. The present method could be considered a valuable tool for assessing inorganic arsenic contents in cereal-based foods. Copyright © 2013 Elsevier Ltd. All rights reserved.

Adducts of 5-hydroxymethylfurfural (HMF)-amino acids are formed during food processing and digestion; the elimination capacity of in vitro intestinal digests of biscuits, instant noodles, and potato crisps for HMF is 652, 727, and 540 μg/g, respectively. However, the safety of these adducts is unknown. In this study, an HMF-cysteine adduct named 1-dicysteinethioacetal-5-hydroxymehtylfurfural (DCH), which was found to be produced in the gastrointestinal tract after HMF intake, was prepared to test its effect toward Caco-2 cells. Compared with HMF, the adduct displayed lower cytotoxicity against Caco-2 cells with an IC 50 value of 31.26 mM versus 14.95 mM (HMF). The DCH did not induce cell apoptosis, whereas HMF significantly increased the apoptosis rate after incubation at concentrations of 16, 32, and 48 mM for 72 h. DCH showed an absorption rate considerably lower than that of HMF by Caco-2 cells. Lower absorption of DCH may result in lower toxicity compared with HMF against Caco-2 cells. Intracellular transformation of DCH has been observed.

A novel GC-MS method was developed for the determination of acrylamide, which is applicable to a variety of processed foods, including potato snacks, corn snacks, biscuits, instant noodles, coffee, soy sauces and miso (fermented soy bean paste). The method involves the derivatization of acrylamide with xanthydrol instead of a bromine compound. Isotopically labelled acrylamide (d₃-acrylamide) was used as the internal standard. The aqueous extract from samples was purified using Sep-Pak™ C₁₈ and Sep-Pak™ AC-2 columns. For amino acid-rich samples, such as miso or soy sauce, an Extrelut™ column was used for purification or extraction. After reaction with xanthydrol, the resultant N-xanthyl acrylamide was determined by GC-MS. The method was validated for various food matrices and showed good linearity, precision and trueness. The limit of detection and limit of quantification ranged 0.5-5 and 5-20 µg kg⁻¹), respectively. The developed method was applied as an exploratory survey of acrylamide in Japanese foods and the method was shown to be applicable for all samples tested.

Shelf life of packaged bakery goods--a review.

Galić, K; Curić, D; Gabrić, D

2009-05-01

Packaging requirements for fresh bakery goods are often minimal as many of the products are for immediate consumption. However, packaging can be an important factor in extending the shelf life of other cereal-based goods (toast, frozen products, biscuits, cakes, pastas). Some amount of the texture changes and flavor loss manifest over the shelf life of a soft-baked good can usually be minimized or delayed by effective use of packaging materials. The gains in the extension of shelf life will be application specific. It is recognized that defining the shelf life of a food is a difficult task and is an area of intense research for food product development scientists (food technologists, microbiologists, packaging experts). Proper application of chemical kinetic principles to food quality loss allows for efficiently designing appropriate shelf-life tests and maximizing the useful information that can be obtained from the resulting data. In the development of any new food product including reformulating, change of packaging, or storage/distribution condition (to penetrate into a new market), one important aspect is the knowledge of shelf life.

2011-09-01

Full Text Available Functional and technological properties of wheat depend on its chemical composition, which together with structural and microscopic characteristics, define flour quality. The aim of the present study was to characterize four Brazilian wheat cultivars (BRS Louro, BRS Timbauva, BRS Guamirim and BRS Pardela and their respective flours in order to indicate specific technological applications. Kernels were analyzed for test weight, thousand kernel weight, hardness, moisture, and water activity. Flours were analyzed for water activity, color, centesimal composition, total dietary fiber, amylose content and identification of high molecular weight glutenins. The rheological properties of the flours were estimated by farinography, extensography, falling number, rapid visco amylography, and glutomatic and glutork equipment. Baking tests and scanning electron microscopy were also performed. The data were subjected to analysis of variance and principal component analysis. BRS Timbauva and BRS Guamirim presented results that did not allow for specific technological application. On the other hand, BRS Louro presented suitable characteristics for the elaboration of products with low dough strength such as cakes, pies and biscuits, while BRS Pardela seemed suitable for bread and pasta products.

Full Text Available The goal of the present study was to quantify the rate and extent of polyphenols released in the gastrointestinal tract (GIT from natural (NS and blanched (BS almond skins. A dynamic gastric model of digestion which provides a realistic simulation of the human stomach was used. In order to establish the effect of a food matrix on polyphenols bioaccessibility, NS and BS were either digested in water (WT or incorporated into home-made biscuits (HB, crisp-bread (CB and full-fat milk (FM. Phenolic acids were the most bioaccessible class (68.5% release from NS and 64.7% from BS. WT increased the release of flavan-3-ols (p < 0.05 and flavonols (p < 0.05 from NS after gastric plus duodenal digestion, whereas CB and HB were better vehicles for BS. FM lowered the % recovery of polyphenols, the free total phenols and the antioxidant status in the digestion medium, indicating that phenolic compounds could bind protein present in the food matrix. The release of bioactives from almond skins could explain the beneficial effects associated with almond consumption.

The method showed satisfactory precision and linearity with instrumental limits of detection (iLODs) ranging from 0.12 to 7.1 pg, for tri- to octa-BDEs and BTBPE, and equal to 51 and 20 pg for BDE-209 and DBDPE, respectively. The highest ΣBFR concentrations were found in fish oil supplements (924 pg/g fresh weight, fw), followed by biscuits (90 pg/g fw), vegetable oil supplements (46 pg/g fw), chicken eggs (45 pg/g fw), cow's milk (7.7 pg/g fw), and soy products (1.6 pg/g fw). BDE-47, BDE-99, and DBDPE were the most abundant compounds. Foodstuffs enriched with omega-3 presented concentrations similar to or even lower than those of conventional foods commercialized in Spain since 2000.

Interventions are required to reduce children's consumption of discretionary foods and drinks. To intervene we need to identify appropriate discretionary choice targets. This study aimed to determine the main discretionary choice contributors to energy and key nutrient intakes in children aged 2-18 years. Secondary analyses were performed with population weighted, single 24 h dietary recall data from the 2011-2012 National Nutrition and Physical Activity Survey. Cakes, muffins, and slices; sweet biscuits; potato crisps and similar snacks; and, processed meats and sugar-sweetened drinks were relatively commonly consumed and were within the top three to five contributors to per capita energy, saturated fat, sodium, and/or added sugars. Per consumer intake identified cereal-based takeaway foods; cakes, muffins and slices; meat pies and other savoury pastries; and, processed meats as top contributors to energy, saturated fat, and sodium across most age groups. Subgroups of sugar-sweetened drinks and cakes, muffins and slices were consistently key contributors to added sugars intake. This study identified optimal targets for interventions to reduce discretionary choices intake, likely to have the biggest impact on moderating energy intake while also reducing intakes of saturated fat, sodium and/or added sugars.

Baking oven improvement by performance modelling

Energy Technology Data Exchange (ETDEWEB)

1994-04-01

The first phase of the project included both the derivation of an oven model and the development of a portable, rapid-response heat-flux sensor. Heat flux (defined as the instantaneous rate of heat flow per unit at the surface of the baking biscuit and expressed in W/cm[sup 2]) has been shown to be a more useful measure of oven performance than temperature alone. Fixed-point heat-flux sensors have already been developed and marketed, but a need was expressed at the start of this project for a travelling sensor which could be used to construct a more detailed picture of heat-flux variation in an oven. The travelling monitor developed can be used to measure variations in the heat flux experienced at the surface of products being baked in a travelling oven, both when oven conditions are fixed and when they are varied. It can also be used to identify the optimum locations within an oven for fixed heat-flux probes. It has been used effectively throughout the project for both purposes. Fuel savings of 18% and 21%, respectively, were achieved with two ovens. (author)

The radioprotective effect of miso, a fermentation product from soy bean, was investigated with reference to the survival time, crypt survival and jejunum crypt length in male B6C3F1 mice. Miso at three different fermentation stages (early-, medium- and long-term fermented miso) was mixed in MF diet into biscuits at 10% and was administered from 1 week before irradiation. Animal survival in the long-term fermented miso group was significantly prolonged as compared with the short-term fermented miso and MF cases after 8 Gy of 60 Co-γ-ray irradiation at a dose rate of 2 Gy min -1 . Delay in mortality was evident in all three miso groups, with significantly increased survival. At doses of 10 and 12 Gy X-irradiation at a dose rate of 4 Gy min -1 , the treatment with long-term fermented miso significantly increased crypt survival. Also the protective influence against irradiation in terms of crypt lengths in the long-term fermented miso group was significantly greater than in the short-term or medium-term fermented miso and MF diet groups. Thus, prolonged fermentation appears to be very important for protection against radiation effects. (author)

The aim of this study was to explore the feasibility of the Mastication Observation and Evaluation (MOE) instrument, dynamic ultrasound and 3D kinematic measurements to describe mastication in children with spastic cerebral palsy and typically developing children. Masticatory movements during five trials of eating a biscuit were assessed in 8 children with cerebral palsy, spastic type (mean age 9.08years) and 14 typically developing children (mean age 9.01years). Differences between trials were tested (t-test) and the mastication of individual children with cerebral palsy was analyzed. MOE scores ranged from 17 to 31 (median 24) for the children with cerebral palsy and from 28 to 32 (median 31) for the typically developing children. There was an increased chewing cycle duration, a smaller left-right and up-down tongue displacement and larger anterior mandible movements for the trials (n=40) of cerebral palsy children (pmastication between individual children with cerebral palsy. The MOE items 'jaw movement' and 'fluency and coordination' showed the most similarity with the objective measurements.

Additions of brown and yellow flax fibre significantly affected Falling Number and Zeleny test values. Curves of farinograph were differed according to flax fibre type - finer flax (better terminology granulation meant somewhat stronger negative changes in dough stability and dough softening degree. Results of extensigraph test demonstrated changes in dough elasticity and extensibility due to lowering of gluten protein content. Appearance of the RVA profiles was verifiably different, reflecting diverse wheat and flax polysaccharides, added dietary fibre type and its granulation. Due to that, bread volume and shape was lowered up to one-half in case of golden flax composites. Similar tendencies with smaller negative influence caused the brown linseed. Fibre from flax is used for technical (textile use, but linseed dietary fibre addition affected quality of laboratory prepared cut-off biscuits and dried pasta differently, showing a dependence on the fibre type, granulation as well as addition level. Sensory profiles of all mentioned product types were acceptable.

Full Text Available ABSTRACT Jabuticaba is a fruit native of Brazil and, besides containing many nutritional qualities, it also has a good field for use in products such as flour for cakes and biscuits, juice, liqueur, jelly and others. This study aimed to model the drying kinetics and determine the thermodynamic properties of jabuticaba peel at different drying air temperatures. Ripe fruits of jabuticaba (Myrciaria jaboticaba were collected and pulped manually. Drying was carried out in a forced-air circulation oven with a flow of 5.6 m s-1 at temperatures of 40, 50, 60 and 70 °C. Six mathematical models commonly used to represent the drying process of agricultural products were fitted to the experimental data. The Arrhenius model was used to represent the drying constant as a function of temperature. The Midilli model showed the best fit to the experimental data of drying. The drying constant increased with the increment in drying temperature and promoted an activation energy of 37.29 kJ mol-1. Enthalpy and Gibbs free energy decreased with the increase in drying temperature, while entropy decreased and was negative.

A solid-phase meal labeled with /sup 99m/Tc-sulfur colloid provides an improved clinical test for the quantitative evaluation of human gastric emptying. We studied 12 healthy male controls and five male patients with known gastric stasis secondary to a vagotomy and drainage procedure. All subjects were fasted for 8 hours before the study, and each consumed an unbuttered biscuit and a poached egg white containing 1 mCi of /sup 99m/Tc-sulfur colloid. For 2 hours, 60-second counts were measured every 10 minutes by a Pho Gamma III scintillation camera. The t/sup 1///sup 2/ for control subjects was 60 minutes, at which time patients with gastric stasis had retained 98% of the test meal. At 120 minutes, control subjects and patients with gastric stasis had 4.7% and 89%, respectively, of the meal remaining in the stomach. The solid-phase test meal labeled with /sup 99m/Tc-sulfur colloid is easy to perform and can be used clinically to quantitatively measure gastric emptying in humans. This test can discriminate between control subjects and patients with known gastric stasis.

To explore the timing of hydrothermal activity at the Upper Geyser Basin (UGB) in Yellowstone National Park, we obtained seven new accelerator mass spectrometry (AMS) radiocarbon 14C ages of carbonaceous material trapped within siliceous sinter. Five samples came from depths of 15-152 cm within the Y-1 well, and two samples were from well Y-7 (depths of 24 cm and 122 cm). These two wells, at Black Sand and Biscuit Basins, respectively, were drilled in 1967 as part of a scientific drilling program by the U.S. Geological Survey (White et al., 1975). Even with samples as small as 15 g, we obtained sufficient carbonaceous material (a mixture of thermophilic mats, pollen, and charcoal) for the 14C analyses. Apparent time of deposition ranged from 3775 ± 25 and 2910 ± 30 14C years BP at the top of the cores to about 8000 years BP at the bottom. The dates are consistent with variable rates of sinter formation at individual sites within the UGB over the Holocene. On a basin-wide scale, though, these and other existing 14C dates hint that hydrothermal activity at the UGB may have been continuous throughout the Holocene.

The aim of this study was to assess the food habits and nutritional status of high level adolescent soccer players (N = 33; ages 14-16 yrs) living in their home environment. Body composition (height, mass, skinfolds), biochemical and hematological parameters, performance in soccer-specific tests (sprinting, jumping, intermittent endurance), and dietary intake (weighed food intake method) and related behaviors (nutrient supplement use, daily activity profile) were assessed. Daily energy expenditure and energy intake were 12.5 MJ and 12.6 MJ, respectively. Protein (16% of energy intake; 1.9 g/kg of body mass), lipid (38%), and cholesterol (385 mg) intake were above recommendations, while carbohydrates (45%) were below. The food intake of these adolescents was based on cereals and derivates; meat, fish, and eggs; milk and dairy products; biscuits and confectionery; and oil, butter and margarine, which provided 78% of total energy intake, 85% of proteins, 64% of carbohydrates, 90% of lipids, and 47% of fiber. Although diet provided sufficient iron, 48% of individuals showed iron deficiency without anemia. Based on these results, a well designed nutrition intervention would be advisable for optimizing performance, and especially for promoting healthy eating habits in adolescent soccer players.

It is crucial that emergent technologies create foods that help prevent the causal mechanisms of the diet induced disease epidemic. Food nanotechnology could create modem convenience foods that mimic and improve on the nutritional value of the most nutritious cooked wild foods for humans. Structuring a solid processed food similar to a celery stalk using self-assembled, water-filled, edible nanocells or nanotubes would substantially lower its energy density (Food technologists could harness the natural turgor force to produce a firm chocolate bar, biscuit or breakfast cereal with a good bite, without altering the appearance or taste of the product. Water carries flavour with few calories, and taste sensation per mouthful could be improved by processing food on the nanoscale to increase the surface area that is in contact with taste and smell receptors. The bioavailable nutrient content (including cofactors) of processed foods could be increased by existing bioactive nanoencapsulation. This would allow people to continue to consume modern convenience food on a mass scale, while simultaneously and significantly increasing nutrient intake and reducing energy intake per day. Thus, helping to reduce mental ill health, obesity and other postprandial insults.

The Malaysian government recently introduced a ban on fast food advertisements targeting children on television. This study reports on data covering 6 months of television food advertising targeting children. Six out of seven of the Nation's commercial television networks participated (response rate = 85.7%). Based on reported timings of children's programmes, prime time significantly differed ( p food advertisements appearing per month varied greatly between television stations (C = 1104; D = 643; F = 407; B = 327; A = 59; E = 47). Food advertising also increased the most in September (n = 3158), followed by July (n = 2770), August (n = 2431), October (n = 2291), November (n = 2245) and June (n = 2211). Content analysis of advertisements indicated snacks were the highest (34.5%), followed by dairy products (20.3%), sugars and candies (13.4%), biscuits (11.2%), fast food (6.7%), breakfast cereal (6.4%), beverages (4.1%), supplements (0.9%), rice (0.6%), noodles (0.5%), bread (0.3%), miscellaneous and processed foods (0.2%). Paradoxically, we found that the frequency of snack food advertised during children's prime time was 5 times more than fast foods. The sodium content (mean = 620 mg per 100g) of these snack foods was found to be highest.

Complete text of publication follows. A number of factors compromise the health of modern people: stressful lifestyle, unbalanced nourishment, excessive consumption of refined foods with a big measure, admission of different chemical agents into the human body. These factors harm directly or indirectly the intestinal activity, that forms a considerable part of the immune system, including the production of essential substances that have beneficial effects on the human body. The role of the so-called prebiotics (e.g. inulin, various oligosaccharides, raffinose, resistant starch etc.) is to prevent and reduce the damage of useful microbes, which are termed as probiotics. These substances selectively facilitate the propagation of probiotic bacteria (e.g. Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium, Lactobacillus acidophilus), therefore increase the rate of the synthesis of vitamin B and of beneficial short chain fatty acids, improve the absorption of minerals, decrease the level of cholesterol, triglycerides, insulin, glucose, ammonia and uric acid and improve the functioning of the immune system. The majority of the examination results about prebiotics are based on clinical dietary and animal experiments. In contrast to this we simulated the process of digestion and the effect of prebiotics on probiotic and non-probiotic bacteria selected by us in an artificial digestion model, the Atlas Potassium reactor system. The instrument enabled the control of pH, temperature, dosage of digestion enzymes and juices (saliva, gastric juice, bile and duodenal juice) and anaerobity in the course of the experiment. In our experiments we investigated different bakery products and biscuits containing various prebiotic ingredients, e.g. inulin and other fructo oligosaccharides. In the digestion model the different bakery products and biscuits got through the simulated oral cavity (pH=6.8), stomach (pH=2-3) and intestine (pH=6.5-7) and might be modified in the

The linkage between mood states and unhealthy food consumption has been under investigation in the recent years. This study aimed to evaluate the associations between posttraumatic stress (PTS) symptoms after lifetime traumatic experiences and daily unhealthy food consumption among adolescents, taking into account the possible effects of physical inactivity, smoking, and a sense of coherence. A self-administered questionnaire measured symptoms of PTS, lifetime traumatic experiences, food frequency scale, sense of coherence scale in a representative sample of eighth grade pupils of the Kaunas, Lithuania, secondary schools (N=1747; 49.3% girls and 50.7% boys). In the logistic regression models, all lifetime traumatic events were associated with PTS symptoms, as well as were unhealthy foods, (including light alcoholic drinks, spirits, soft and energy drinks, flavored milk, coffee, fast food, chips and salty snacks, frozen processed foods; excluding sweet snacks, biscuits and pastries) and sense of coherence weakened the strength of the associations. However, physical inactivity and smoking showed no mediating effect for the majority of unhealthy foods. In conclusion, we found that intervention and preventive programs on PTS symptoms may be beneficial while dealing with behavioral problems (unhealthy diet, smoking, alcohol, physical inactivity) among adolescents.

Cinnamon is a traditional herbal drug, but more importantly, it is used as a flavor compound in the production of foodstuff. Due to the content of significant concentrations of coumarin in Cassia cinnamon, effective control of the coumarin content in seasonal bakery products like ginger bread and cinnamon biscuits is urgently needed. Here we present a novel, fast and fully validated protocol for the determination of coumarin in marketed bakery products using the QuEChERS sample preparation technique in combination with GC-MS analysis. Ten grams of homogenized sample was mixed with 20 mL acetonitrile/water (1:1) and 5 g magnesium sulfate/sodium chloride mixture (4:1). The organic phase was cleaned by dSPE with 25 mg magnesium sulfate/PSA (5:1). The LOD was 0.15 μg/mL and the LOQ 0.50 μg/mL. We detected a mean coumarin content of 19.5 μg/kg in 9 out of 14 seasonal food products (ranging from 1.45 to 39.4 mg/kg). No coumarin was detected in five cinnamon containing products. With this investigation we demonstrate that the QuEChERS sample preparation, previously applied mainly to the analysis of pesticides in vegetables, is also suitable for other complex matrices.

The objective of this research was to estimate the processing effect on mycotoxins levels and the exposure to zearalenone (ZEA), ochratoxin (OTA) and aflatoxin B1 (AFB1) through the consumption of pasta and bakery products. The higher reduction percentage of mycotoxins was observed in cake production (95, 90 and 70% for ZEA, OTA and AFB1, respectively). Bread and biscuit showed similar reduction in mycotoxins levels (89 and 90% for ZEA; 80 and 85% for OTA; 36 and 40% for AFB1, respectively). The lower reduction in the levels of mycotoxins has been observed for pasta (75, 65 and 10% for ZEA, OTA and AFB1, respectively). The consumption of these products could represent 12.6% of the maximum tolerable daily intake of ZEA and 30.5% of the tolerable weekly intake of OTA. The margin of exposure value related to the exposure to AFB1 was 24.6. The exposure to ZEA and OTA through the consumption of bakery products and pasta would not represent risk for consumer health, (although conjugated forms were not determined). However, the exposure to AFB1 represents a risk (even without considering the AFB1-conjugated forms). Copyright © 2016 Elsevier Ltd. All rights reserved.

Full Text Available The objective of this study was to prepare roasted and lyophilized tempeh flour with soybean cultivar BRS 267 to apply them in the formulation of coconut biscuits. The cookies produced with whole soy flour and mixed flour of soybean and tempeh were evaluated for proximate composition, fatty acid profile, and isoflavone aglycones in order to verify the effects of inoculation with the fungus Rhizopus oligosporus and those of the drying processes of roasting and lyophilization on the chemical characteristics of the final product. Sensory acceptance and purchase intention of the formulated products were also evaluated. The results indicate the maintenance of linolenic acid, which is important in the prevention of coronary diseases, and an increase in the aglycones levels when the tempeh flour was used. Lipids and proteins showed differences, and the sensory analyses demonstrated similarity between the cookies with satisfactory scores for aroma, flavor, texture, and overall acceptability for both samples. when compared to the control. Purchase intent was also positive for the lyophilized and toasted tempeh flours, thus enabling the use of the roasting process as a simple drying method, for processing tempeh and obtaining a flour rich in proteins and aglycones that can be used as a partial substitute for soy flour in cookies and other bakery products.

To examine the intake and sources of added sugars (AS) of Australian children and adolescents, and compare their intake of free sugars (FS) to the recommended limit set by the World Health Organization (foods was estimated based on a published method. Intakes of AS and FS, as well as food sources of AS, were calculated. One-way ANOVA was used for comparisons between age groups and gender. The mean (SD) AS intake was 58.9 (35.1) g/day, representing 11.9 (5.6) % of daily energy intake and 46.9 (17.5) % of daily total sugars intake. More than 80 % of the subjects had % energy from FS > 10 %. Significant increasing trends for AS intake, % energy from AS, % energy from FS across age groups were observed. Sugar-sweetened beverages (19.6 %), cakes, biscuits, pastries and batter-based products (14.3 %), and sugar and sweet spreads (10.5 %) were the top three contributors of AS intake in the whole sample. Higher contribution of AS from sugar-sweetened beverages was observed in adolescents (p trend  foods, interventions which target the reduction in these foods would reduce energy and AS intake with minimal impact to core nutrient intake.

Acrylamide is a heat-induced carcinogen compound that is found in some foods consequently to cooking or other thermal processes. In the second French Total Diet Study (TDS), acrylamide was analysed in 192 food samples collected in mainland France to be representative of the population diet and prepared "as consumed". Highest mean concentrations were found in potato chips/crisps (954 μg/kg), French fries and other fried potatoes (724 μg/kg), and salted biscuits other than potato chips (697 μg/kg). Exposure of general adult and child populations was assessed by combining analytical results with national consumption data. Mean acrylamide exposure was assessed to be 0.43±0.33 μg/kg of body weight (bw) per day for adults and 0.69±0.58 μg/kg bw/day for children. Although the exposure assessed is lower than in previous evaluations, the calculated margins of exposure, based on benchmark dose limits defined for carcinogenic effects, remain very low especially for young children (below 100 at the 95th percentile of exposure), indicating a health concern. It is therefore advisable to continue efforts in order to reduce dietary exposure to acrylamide. Copyright © 2012 Elsevier Ltd. All rights reserved.

Interventions are required to reduce children’s consumption of discretionary foods and drinks. To intervene we need to identify appropriate discretionary choice targets. This study aimed to determine the main discretionary choice contributors to energy and key nutrient intakes in children aged 2–18 years. Secondary analyses were performed with population weighted, single 24 h dietary recall data from the 2011–2012 National Nutrition and Physical Activity Survey. Cakes, muffins, and slices; sweet biscuits; potato crisps and similar snacks; and, processed meats and sugar-sweetened drinks were relatively commonly consumed and were within the top three to five contributors to per capita energy, saturated fat, sodium, and/or added sugars. Per consumer intake identified cereal-based takeaway foods; cakes, muffins and slices; meat pies and other savoury pastries; and, processed meats as top contributors to energy, saturated fat, and sodium across most age groups. Subgroups of sugar-sweetened drinks and cakes, muffins and slices were consistently key contributors to added sugars intake. This study identified optimal targets for interventions to reduce discretionary choices intake, likely to have the biggest impact on moderating energy intake while also reducing intakes of saturated fat, sodium and/or added sugars.

Dietary behaviour modification may change eating habits and reduce the impact of poor nutrition. This study aimed to evaluate the effects of daily consumption of a healthier snack bar on snacking habits and glycated Hb (HbA1c) within a 6-week intervention. In all, twenty-eight participants were randomly allocated to two groups to either consume the bars as the main snack for 6 weeks (n 14) or receipt of the bars was delayed for 6 weeks (n 14) following a stepped-wedge design. All participants had HbA1c concentrations measured at weeks -1, 0, 4, 6, 10 and 12. A short dietary habits questionnaire was self-completed at weeks 0, 6 and 12. Participants consumed the bars they received instead of other snacks, and found that the healthier snack bar was acceptable as part of their daily dietary pattern. Over the 12 weeks, there was a significant reduction in intake of biscuits, cakes and pies (approximately 2 servings/week, Psnack intervention and a trend towards a favourable effect on glucose homoeostasis. Habitual snacking behaviour has the potential to be improved through changes in the food supply, and in the longer term may reduce the impact of poor nutrition on public health.

Fast growing food processing industry in most countries across the world, generates huge quantity of by-products, including pomace, hull, husk, pods, peel, shells, seeds, stems, stalks, bran, washings, pulp refuse, press cakes, etc., which have less use and create considerable environmental pollution. With growing interest in health promoting functional foods, the demand of natural bioactives has increased and exploration for new sources is on the way. Many of the food processing industrial by-products are rich sources of dietary, functional, and novel fibers. These by-products can be directly (or after certain modifications for isolation or purification of fiber) used for the manufacture of various foods, i.e. bread, buns, cake, pasta, noodles, biscuit, ice creams, yogurts, cheese, beverages, milk shakes, instant breakfasts, ice tea, juices, sports drinks, wine, powdered drink, fermented milk products, meat products and meat analogues, synthetic meat, etc. A comprehensive literature survey has been carried on this topic to give an overview in the field dietary fiber from food by-products. In this article, the developments in the definition of fiber, fiber classification, potential sources of dietary fibers in food processing by-products, their uses, functional properties, caloric content, energy values and the labelling regulations have been discussed.

Salt-soluble proteins from wheat flour have been described as main allergens associated with both baker's asthma and food allergy. However, most studies have used raw flour as starting material, thus not considering potential changes in allergenic properties induced by the heat treatment and other industrial processing to produce wheat-derived foodstuffs. Salt extracts from different commercial wheat-derived products were obtained and their allergenic properties investigated by IgE-immunodetection, ELISA assays, and skin prick test. The IgE-binding capacity of salt-soluble proteins from commercial breads and cooked pastas was reduced around 50% compared with that of raw flour, the reduction being less dramatic in noncooked pastas and biscuits. Several wheat-derived foodstuffs showed major IgE-binding components of 20 and 35 kDa, identified as avenin-like and globulin proteins, respectively. These proteins, as well as most flour and bread salt-soluble proteins, were hydrolyzed when subjected to simulated gastrointestinal digestion. However, the digested products still exhibited a residual IgE-binding capacity. Therefore, processing of wheat flour to obtain derived foodstuffs decreases the IgE binding-capacity of the major salt-soluble wheat proteins. Moreover, simulated gastric fluid digestion further inactivates some heat-resistant IgE-binding proteins.

Full Text Available ABSTRACT Wheat flour can be allocated for manufacturing various products, but each purpose requires specificities defined by the industrial quality. The objective of this study was to evaluate the performance of experimental lines and commercial cultivars of wheat, in South and Southeast of Brazil and to identify genotypes with favorable characteristics of industrial quality. Twenty lines in the stage of cultivation and use and three commercial cultivars were evaluated for grain yield components (hectoliter weight and thousand-grain weight and features related to the industrial quality of the flour (protein, flour stability, sedimentation with sodium dodecyl sulfate and color. The genotypes CRX/CD104//ALC, LAJ96010/JSP//ALC and CRX/ALC//ALC showed favorable characteristics for biscuit production, while the genotypes ORL97061/ORL00241//CD104, SUZ6/WEAVER//TUI/3/SUP/4/CD104, ORL99396/ORL97061//SUP, CRX/CD104//ALC, ORL98231/IOR00131//ÔNIX, ORL94346/ALC//AVT/3/ÔNIX, CEP0033/ÔNIX/3/ÔNIX*2//TC14/2*SPEAR, Campo Real/VAN//ÔNIX, ORL97061/CD 104 and PMP/ORL98231//CRX have aptitude for baking. The evaluations were efficient for the classification and selection of genotypes in the wheat breeding program.

Recently we have proposed a new variable selection algorithm, based on clustering of variable concept (CLoVA) in classification problem. With the same idea, this new concept has been applied to a regression problem and then the obtained results have been compared with conventional variable selection strategies for PLS. The basic idea behind the clustering of variable is that, the instrument channels are clustered into different clusters via clustering algorithms. Then, the spectral data of each cluster are subjected to PLS regression. Different real data sets (Cargill corn, Biscuit dough, ACE QSAR, Soy, and Tablet) have been used to evaluate the influence of the clustering of variables on the prediction performances of PLS. Almost in the all cases, the statistical parameter especially in prediction error shows the superiority of CLoVA-PLS respect to other variable selection strategies. Finally the synergy clustering of variable (sCLoVA-PLS), which is used the combination of cluster, has been proposed as an efficient and modification of CLoVA algorithm. The obtained statistical parameter indicates that variable clustering can split useful part from redundant ones, and then based on informative cluster; stable model can be reached.

2011-12-01

The Dutch'Task Force for the Improvement of the Fatty Acid Composition' initiated fatty acid reformulations in branches using vegetable oils and fats to reduce the trans (TFA) and saturated fatty acid (SFA) content of foods. This study estimates the impact of recent reformulations in the task force food groups by estimating changes in median intake of TFA and SFA in Dutch young adults. This is a modelling study with food consumption data of young adults. Intakes were estimated before reformulation using food composition data of 2001 as a reference and while including most recent fatty acid composition of foods for task force food groups. Food composition of other foods and food consumption was assumed unchanged. Average TFA intake significantly decreased from 1.0 E% in the reference to 0.8 E% in the reformulation scenario. Pastry, cakes and biscuits, and snacks contributed most to the decrease of TFA. Estimated SFA intake did not change. When solid baking and spreading fats were additionally replaced with fluid ones, SFA intake decreases from 12.9 E% to 12.1 E%. Fatty acid reformulation in the task force food groups contributed to reductions in TFA intake. For further reductions in SFA intake a different food choice is primordial.

Full Text Available Kiwifruit (KF effects on the human glycaemic response to co-ingested wheat cereal were determined. Participants (n = 20 consumed four meals in random order, all being made to 40 g of the same available carbohydrate, by adding kiwifruit sugars (KF sug; glucose, fructose, sucrose 2:2:1 to meals not containing KF. The meals were flaked wheat biscuit (WB+KFsug, WB+KF, WB+guar gum+KFsug, WB+guar gum+KF, that was ingested after fasting overnight. Blood glucose was monitored 3 h and hunger measured at 180 min post-meal using a visual analogue scale. KF and guar reduced postprandial blood glucose response amplitude, and prevented subsequent hypoglycaemia that occurred with WB+KFsug. The area between the blood glucose response curve and baseline from 0 to 180 min was not significantly different between meals, 0–120 min areas were significantly reduced by KF and/or guar. Area from 120 to 180 min was positive for KF, guar, and KF+guar, while the area for the WB meal was negative. Hunger at 180 min was significantly reduced by KF and/or guar when compared with WB. We conclude that KF components other than available carbohydrate may improve the glycaemic response profile to co-ingested cereal food.

Aluminum bioavailability from basic sodium aluminum phosphate, an approved food additive emulsifying agent, incorporated in cheese.

Yokel, Robert A; Hicks, Clair L; Florence, Rebecca L

2008-06-01

Oral aluminum (Al) bioavailability from drinking water has been previously estimated, but there is little information on Al bioavailability from foods. It was suggested that oral Al bioavailability from drinking water is much greater than from foods. The objective was to further test this hypothesis. Oral Al bioavailability was determined in the rat from basic [26Al]-sodium aluminum phosphate (basic SALP) in a process cheese. Consumption of approximately 1g cheese containing 1.5% or 3% basic SALP resulted in oral Al bioavailability (F) of approximately 0.1% and 0.3%, respectively, and time to maximum serum 26Al concentration (Tmax) of 8-9h. These Al bioavailability results were intermediate to previously reported results from drinking water (F approximately 0.3%) and acidic-SALP incorporated into a biscuit (F approximately 0.1%), using the same methods. Considering the similar oral bioavailability of Al from food vs. water, and their contribution to the typical human's daily Al intake ( approximately 95% and 1.5%, respectively), these results suggest food contributes much more Al to systemic circulation, and potential Al body burden, than does drinking water. These results do not support the hypothesis that drinking water provides a disproportionate contribution to total Al absorbed from the gastrointestinal tract.

Yokel, Robert A; Florence, Rebecca L

2008-12-01

The objective was to estimate oral Al bioavailability from tea infusion in the rat, using the tracer (26)Al. (26)Al citrate was injected into tea leaves. An infusion was prepared from the dried leaves and given intra-gastrically to rats which received concurrent intravenous (27)Al infusion. Oral Al bioavailability (F) was calculated from the area under the (26)Al, compared to (27)Al, serum concentration x time curves. Bioavailability from tea averaged 0.37%; not significantly different from water (F=0.3%), or basic sodium aluminum phosphate (SALP) in cheese (F=0.1-0.3%), but greater than acidic SALP in a biscuit (F=0.1%). Time to maximum serum (26)Al concentration was 1.25, 1.5, 8 and 4.8h, respectively. These results of oral Al bioavailability x daily consumption by the human suggest tea can provide a significant amount of the Al that reaches systemic circulation. This can allow distribution to its target organs of toxicity, the central nervous, skeletal and hematopoietic systems. Further testing of the hypothesis that Al contributes to Alzheimer's disease may be more warranted with studies focusing on total average daily food intake, including tea and other foods containing appreciable Al, than drinking water.

Dust exposure and pneumoconiosis in a South African pottery. 1. Study objectives and dust exposure.

1992-07-01

Dust exposure and pneumoconiosis were investigated in a South African pottery that manufactured wall tiles and bathroom fittings. This paper describes the objectives of the investigation and presents dust measurement data. x Ray diffraction showed that the clays used by the pottery had a high quartz content (range 58%-23%, mean 38%). Exposure to respirable dust was measured for 43 workers and was highest (6.6 mg/m3) in a bathroom fitting fettler. Quartz concentrations in excess of 0.1 mg/m3 were found in all sections of the manufacturing process from slip production to biscuit firing and sorting. The proportion of quartz in the respirable dust of these sections was 24% to 33%. This is higher than is usually reported in English potteries. Four hundred and six (80%) of the 509 workers employed at the pottery were potentially at risk of occupational lung disease. The finding of large numbers of pottery workers exposed to unacceptable dust concentrations is not surprising as poor dust control was found in all six wall tile and sanitary ware factories surveyed by the National Centre for Occupational Health between 1973 and 1989. Dust related occupational disease can be expected in potters for many years to come.

Per consumer intake identified cereal-based takeaway foods; cakes, muffins and slices; meat pies and other savoury pastries; and, processed meats as top contributors to energy, saturated fat, and sodium across most age groups. Subgroups of sugar-sweetened drinks and cakes, muffins and slices were consistently key contributors to added sugars intake. This study identified optimal targets for interventions to reduce discretionary choices intake, likely to have the biggest impact on moderating energy intake while also reducing intakes of saturated fat, sodium and/or added sugars.

Previous research investigating the relationship between parents' and children's diets has focused on single foods or nutrients, and not on global diet, which may be more important for good health. The aim of the study was to investigate the relationship between parental diet quality and child dietary patterns. A cross-sectional survey was conducted in 17 primary schools in Dunedin, New Zealand. Information on food consumption and related factors in children and their primary caregiver/parent were collected. Principal component analysis (PCA) was used to investigate dietary patterns in children and diet quality index (DQI) scores were calculated in parents. Relationships between parental DQI and child dietary patterns were examined in 401 child-parent pairs using mixed regression models. PCA generated two patterns; 'Fruit and Vegetables' and 'Snacks'. A one unit higher parental DQI score was associated with a 0.03SD (CI: 0.02, 0.04) lower child 'Snacks' score. There was no significant relationship between 'Fruit and Vegetables' score and parental diet quality. Higher parental diet quality was associated with a lower dietary pattern score in children that was characterised by a lower consumption frequency of confectionery, chocolate, cakes, biscuits and savoury snacks. These results highlight the importance of parental modelling, in terms of their dietary choices, on the diet of children.

Full Text Available Idiopathic chronic enterocolitis (ICE is one of the most commonly encountered and difficult to manage diseases of captive rhesus macaques (Macaca mulatta. The etiology is not well understood, but perturbations in gut microbial communities have been implicated. Here we evaluated the effects of a 14-day course of vancomycin, neomycin, and fluconazole on animals affected with ICE, comparing treated, untreated, and healthy animals. We performed microbiome analysis on duodenal and colonic mucosal samples and feces in order to probe bacterial and/or fungal taxa potentially associated with ICE. All treated animals showed a significant and long-lasting improvement in stool consistency over time when compared to untreated and healthy controls. Microbiome analysis revealed trends associating bacterial community composition with ICE, particularly lineages of the Lactobacillaceae family. Sequencing of DNA from macaque food biscuits revealed that fungal sequences recovered from stool were dominated by yeast-derived food additives; in contrast, bacteria in stool appeared to be authentic gut residents. In conclusion, while validation in larger cohorts is needed, the treatment described here was associated with significantly improved clinical signs; results suggested possible correlates of microbiome structure with disease, though no strong associations were detected between single microbes and ICE.

The aim of this study was to develop a gluten-free formulation of quinoa (Chenopodium quinoa Willd.)-based cookies using experimental design of mixture to optimize a ternary mixture of quinoa flour, quinoa flakes and corn starch for parameters of colour, specific volume and hardness. Nutritional and sensory aspects of the optimized formulation were also assessed. Corn starch had a positive effect on the lightness of the cookies, but increased amounts of quinoa flour and quinoa flakes in the mixture resulted in darker product. Quinoa flour showed a negative effect on the specific volume, producing less bulky cookies, and quinoa flour and quinoa flakes had a positive synergistic effect on the hardness of the cookies. According the results and considering the desirability profile for colour, hardness and specific volume in gluten-free cookies, the optimized formulation contains 30 % quinoa flour, 25 % quinoa flakes and 45 % corn starch. The quinoa-based cookie obtained was characterized as a product rich in dietary fibre, a good source of essential amino acids, linolenic acid and minerals, with good sensory acceptability. These findings reports for the first time the application of quinoa processed as flour and flakes in mixture with corn starch as an alternative ingredient for formulations of gluten-free cookies-type biscuits.

Insect pests are responsible for substantial damage to museum objects, historic books and in buildings like palaces or historic houses. Different wood boring beetles (Anobium punctatum, Hylotrupes bajulus, Lyctus sp. or introduced species), the biscuit beetle (Stegobium paniceum), the cigarette beetle (Lasioderma serricorne), different Dermestides (Attagenus sp., Anthrenus sp., Dermestes sp., Trogoderma sp.), moths like the webbing clothes moth (Tineola bisselliella), Silverfish (Lepisma saccharina) and booklice (Psocoptera) can damage materials, objects or building parts. They are the most common pests found in collections in central Europe, but most of them are distributed all over the world. In tropical countries, termites, cockroaches and other insect pests are also found and result in even higher damage of wood and paper or are a commune annoyance in buildings. In this short review, an introduction to Integrated Pest Management (IPM) in museums is given, the most valuable collections, preventive measures, monitoring in museums, staff responsible for the IPM and chemical free treatment methods are described. In the second part of the paper, the most important insect pests occurring in museums, archives, libraries and historic buildings in central Europe are discussed with a description of the materials and object types that are mostly infested and damaged. Some information on their phenology and biology are highlighted as they can be used in the IPM concept against them.

This study aimed to examine the changes in typical portion sizes of commonly consumed discretionary foods among Australian adults from 1995 to 2011–2012. Data of adults (age ≥19 years) from the 1995 Australian National Nutrition Survey and 2011–2012 National Nutrition and Physical Activity Survey were used. Typical portion sizes (median portion) of fourteen discretionary foods that contributed the most to energy intake were determined. Ten out of fourteen food categories demonstrated a significant change in kJ per typical portion from 1995 to 2011–2012 (p ≤ 0.001). kJ per typical portion increased for pizza, cake, sausage, cereal bar, processed meat, ice cream and wine, with pizza and cake demonstrating the largest increases (+570 kJ and +950 kJ in 2011–2012, respectively; both +66% above 1995). In contrast, kJ per typical portion of pastry, snack food and potato fries decreased by 10–40% over time, and did not change for biscuit, chocolate, sugar-sweetened beverage and beer. Similar changes were observed for grams per typical portion consumed. Temporal trends in typical portion sizes were similar according to age group, gender and socioeconomic status. The findings suggest that population-wide strategies that enable consumers to choose smaller portions of discretionary foods are needed to reduce the excess consumption of these products.

Full Text Available Abstract The goal of this study was to analyze cytotoxicity, genotoxicity and mutagenicity to bone marrow cells of mice of nature identical synthetic flavorings, passion fruit and strawberry, and artificial synthetic flavorings, vanilla, chocolate, tutti-frutti and cookie, at doses 0.5; 1.0; 2.0; 5.0 and 10.0 mL/kg. The additives were given to the animals by gavage in a single daily application for seven days. Data were subjected to analysis of variance (ANOVA followed by post Tukey’s post hoc test, p <0.05. Animals treated with 2.0; 5.0 and 10.0 mL/Kg of flavorings chocolate, strawberry and cookie, and 5.0 and 10.0 mL/Kg of flavorings vanilla and passion fruit died on the fifth and sixth day of the experiment, respectively. The doses 0.5 and 1.0 mL/Kg of the six additives significantly reduced erythropoiesis in the examined tissue. Also, treatments 0.5 and 1.0 mL/Kg of chocolate, and 1.0 mL/Kg of strawberry and biscuit induced the formation of micronuclei in the bone marrow erythrocytes, at a significant frequency. Therefore, under the study conditions, the six microingredients analyzed were cytotoxic and genotoxic, and additives strawberry, chocolate and cookie were also mutagenic in at least one of the evaluated doses.

Full Text Available The caja (Spondias mombin L. is used in the manufacture of ice-cream, jams, pulps, beverages being also consumed in natura. One of the most important procedures in food conservation is drying, considering that most fresh fruits contain approximately 80% of water. Food drying is used to obtain two basic aspects: (1 the economic factor; in the shipping and handling of the product; (2 at the manipulation; once dried and grinded, the material is rehydrated, at desirable levels, to formulate a new product as in ice cream, jams, yoghurts and drinks and may also be added to pasta, biscuits and other industrialized products. The aim of this study was to investigate the kinetics of caja bagasse drying in a fixed-bed tray dryer, using central composite factorial planning. The following factors were evaluated: temperature (55, 65 and 75 ºC, dryer inlet air velocity (3.2, 4.6 and 6.0 m.s-1 and cake thickness (0.8, 1.2 and 1.6 cm where the response of the considered variable was caja bagasse moisture content (b.s. and the results showed that the main effects and their interactions were significant at a 95% confidence level being the best condition obtained at temperature of 75 ºC, velocity of 6.0 m.s-1 and cake thickness of 0.8 cm.

Long and Short-Term Effects of Fire on Soil Charcoal of a Conifer Forest in Southwest Oregon

Full Text Available In 2002, the Biscuit Wildfire burned a portion of the previously established, replicated conifer unthinned and thinned experimental units of the Siskiyou Long-Term Ecosystem Productivity (LTEP experiment, southwest Oregon. Charcoal C in pre and post-fire O horizon and mineral soil was quantified by physical separation and a peroxide-acid digestion method. The abrupt, short-term fire event caused O horizon charcoal C to increase by a factor of ten to >200 kg C ha⁻¹. The thinned wildfire treatment produced less charcoal C than unthinned wildfire and thinned prescribed fire treatments. The charcoal formation rate was 1 to 8% of woody fuels consumed, and this percentage was negatively related to woody fuels consumed, resulting in less charcoal formation with greater fire severity. Charcoal C averaged 2000 kg ha⁻¹ in 0–3 cm mineral soil and may have decreased as a result of fire, coincident with convective or erosive loss of mineral soil. Charcoal C in 3–15 cm mineral soil was stable at 5500 kg C ha⁻¹. Long-term soil C sequestration in the Siskiyou LTEP soils is greatly influenced by the contribution of charcoal C, which makes up 20% of mineral soil organic C. This research reiterates the importance of fire to soil C in a southwestern Oregon coniferous forest ecosystem.

Overweight and obesity in Australia is an emerging health concern. Obesity prevention initiatives must consider both physical activity and nutrition to be effective. Community sports venues have the capacity to promote healthy lifestyles through physical activity as well as healthy food choices. A telephone survey was conducted on parents of children aged 5-17 years in NSW to determine the nature of food and beverages purchased by children at community sporting venues and to determine parent's perception of the role that government should play in regulating the types of food and beverages sold at these outlets. The majority of canteens at children's sporting venues were considered to sell mostly unhealthy food and beverages (53%). Very few parents reported that canteens sold mostly healthy food and beverages. Parents reported that their child's most frequently purchased food and beverage items at outdoor sports fields were water, chocolate and confectionery, soft drink and sports drinks, and ice cream. At community swimming pools the most frequently purchased items were ice cream, followed by snack foods, including chips, cakes and biscuits. Most parents (63%) agreed that government should restrict the types of food and beverages that can be sold at children's sporting venues. Children are receiving inconsistent health messages at sporting venues, with healthy lifestyles being promoted through sports participation, but unhealthy dietary choices being provided at sports canteens.

The baby-led weaning philosophy proposes that when solids are introduced, infants should be encouraged to self-feed with solid food, as opposed to spoon-feeding purees. We used data from the Gateshead Millennium Study (GMS) to define the range of ages at which infants reach out for and eat finger foods and related this to developmental status. GMS recruited infants shortly after birth and followed them prospectively using postal questionnaires. Of the 923 eligible children, 602 had data on when they first reached out for food, and 340 (56%) had done so before age 6 months, but 36 (6%) were still not reaching for food at age 8 months. Infants who had not reached out for food by 6 months were less likely to be walking unaided at age 1 year (85 out of 224, 38%) compared with those who did (155 out of 286, 54%; P bread, rusks or biscuits. Of the 604 with information at age 8 months about current intake, all but 58 (9.6%) were having some finger foods at least daily, but only 309 (51%) were having them more than once per day. Baby-led weaning is probably feasible for a majority of infants, but could lead to nutritional problems for infants who are relatively developmentally delayed. © 2010 Blackwell Publishing Ltd.

Full Text Available Golden snail Pomaceae canaliculata is a pest of rice plants and used as a food source to be processed into satay seasoning spices biscuits pastry candy crackers animal feed and fertilizer. In Lae Parira village the golden snail is very diverse. Because of this reason the preliminary study and utilization of golden snail used for of liquid organic fertilizer called LOF or and microorganisms local MOL. The golden snail is obtained from a livestock that is still alive and then washed boiled and removed from its shell. The golden snail meat is cut into small pieces separated from the intestine and other visceral organs. Flesh of golden snail give coconut water dilute brown sugar EM4 and fermentation until 10-14 days. The use of mashed LOF can be sprayed on the surface of the soil or all parts of the plant. For fertilization in rice plants the recommended dose of 250 ml15 liters of water is sprayed on the rice age 10 days after planting and repeated again at interval distance of 15 days. Fertilization on the plant recommended 200ml 15 liters of water sprayed on leaves and soil 7 days after planting and repeated every 7 days. The golden snail is potensial used for fertilizer in paddy plantation environmentally.

This double-blind, randomized, controlled study assessed the effect of esterified propoxylated glycerol (EPG) on fat-soluble vitamins and select nutrients in human subjects. For 8 weeks, 139 healthy volunteers consumed a core diet providing adequate caloric and nutrient intakes. The diet included items (spread, muffins, cookies, and biscuits) providing EPG (10, 25, and 40 g/day) vs. margarine alone (control). EPG did not significantly affect circulating retinol, α-tocopherol, or 25-OH D2, but circulating β-carotene and phylloquinone were lower in the EPG groups, and PIVKA-II levels were higher; 25-OH D3 increased but to a lesser extent than the control. The effect might be related to EPG acting as a lipid "sink" during gastrointestinal transit. No effects were seen in secondary endpoint measures (physical exam, clinical pathology, serum folate, RBC folate, vitamin B12, zinc, iron, calcium, phosphorus, osteocalcin, RBP, intact PTH, PT, PTT, cholesterol, HDL-C, LDL-C, triglycerides). Gastrointestinal adverse events (gas with discharge; diarrhea; oily spotting; oily evacuation; oily stool; liquid stool; soft stool) were reported more frequently by subjects receiving 25 or 40 g/day of EPG. In general, the incidence and duration of these symptoms correlated directly with EPG dietary concentration. The results suggest 10 g/day of EPG was reasonably well tolerated.

Added sugars provide calories and desirability to foods and beverages. Our aim was to test whether desire for a sweet taste would be better maintained than a desire for other tastes for 3 hours after a test meal. Eighty-three young adults ate 2 slices of bread on 2 separate occasions after which they were asked to rate their desire for savory, sweet, fatty, or salty tastes and to specify the number of servings of white rice, pizza, cheese and crackers, sweet biscuits, and pasta they could consume. Desirability was assessed using 100-mm visual analog scales (VAS), with 0 mm representing no desire and 100 mm great desire. When participants provided a quantitative assessment of the servings of foods that they wanted to eat following the bread meal, desire decreased on average for all foods measured, χ 2 (3) = 2.63, p = 0.452. Mean (95% confidence interval [CI]) change in VAS taste desirability 30 minutes after eating declined for salty (14.5 mm [10.5, 18.6]), fatty (11.2 mm [7.1, 15.2]), and savory (24.1 mm [19.7, 28.5]) tastes (p foods and beverages. Targeting familial and cultural practices that discourage the consumption of added sugar foods might be useful to combat desire-driven food intake.

In light of the increasing prevalence of obesity in children and the potential of schools as a setting for intervention, we aimed to identify the main foods and beverages consumed at primary school and to determine differences in consumption patterns between children who used the school canteen and those who did not. Cross-sectional survey of school foods in 1681 5-12 y old children, 2003-2004. Barwon South-Western region of Victoria, Australia. The school food provided an average (+/-s.e.m.) of 3087+/-26 kJ. Bread was the most frequently consumed food and contributed 20% of total energy at school, biscuits 13%, fruit 10%, muesli/fruit bars 8%, packaged snacks 7%, and fruit juice/cordial 6%. About 10% of children used the school canteen and these children obtained more total energy and more energy from cakes, fast foods and soft drink than noncanteen users (Pjunk food'). Fruit intake in primary schools seems reasonably high but could be targeted for further increase as part of promoting a healthy diet. Of concern, however, are the excessive amounts of energy-dense foods in school lunchboxes. These should be considered a priority for health promotion efforts along with reducing the consumption of sweetened drinks. These measures are urgently needed to improve the school-based diets of Australian children and attempt to curb the increasing prevalence of childhood obesity.

Adequate nutrition during complementary feeding is important for the growth, development and well-being of children. We aim to examine the energy and macronutrient intake composition and their main food sources in a mother-offspring cohort study in Singapore. The diets of infants were assessed by 24 h dietary recalls or food diaries collected from mothers when their offspring were 6 (n = 760), 9 (n = 893) and 12 (n = 907) months of age. Food sources of energy and macronutrients were determined using the population proportion methodology. Energy intakes per day (kcal; mean (standard deviation, SD)) of these infants were 640 (158) at 6 months, 675 (173) at 9 months, and 761 (208) at 12 months. Infant formula, breastmilk and infant cereals were the top three food sources of energy and macronutrient intakes in infants through the period 6 to 12 months. Other main energy and carbohydrate sources at 9 and 12 months of age were rice porridge, infant biscuits and fresh fruits, while fish, red meat and eggs were the other main protein and total fat sources. Breast-fed and mixed-fed infants had a more varied diet as compared to formula-fed infants. Formula-fed infants had consistently higher protein and lower total fat consumption compared to those who were breastfed. An understanding of these main food sources during complementary feeding can inform local dietary recommendations and policies.

Obesity is at crisis proportions. Individuals of low socio-economic status (SES) are more likely to consume higher energy dense diets than their high socio-economic status counterparts. The contribution of supermarket purchases of energy dense, nutrient poor foods has not been well-researched and has largely depended on unverified self-report. We estimated the proportion of supermarket shelf space dedicated to non-core foods in nine supermarkets (in five high and four low SES areas) in metropolitan Sydney. We analysed 204 shoppers' dockets (102 from high and 102 from low SES areas) for purchases of confectionery; sugar sweetened, carbonated beverages and cordials, sweet biscuits and cakes, and crisps and popcorn. After adjusting for the number of people shopped for, low SES shoppers purchased significantly more non-core foods than high SES shoppers (p=0.039), especially chips and sugar sweetened, carbonated beverages and cordials. There was no difference in the shelf space dedicated to non-core foods, or between non-core foods purchased and the proportion of shelf space occupied by them in either low or high SES areas. Increased purchase of non-core foods by low SES shoppers who are already at higher risk of obesity than high SES shoppers is cause for concern. Further research is required to explore underlying reasons for this association.

Phytic acid (PA), a naturally occurring compound of plant food, is generally considered to affect mineral bioavailability. The aim of this study was to investigate the reliability of the PA/calcium molar ratio as a predictive factor of calcium accessibility in composed dishes and their ingredients. Dishes were chosen whose ingredients were rich in Ca (milk or cheese) or in PA (whole-wheat cereals) in order to consider a range of PA/Ca ratios (from 0 to 2.4) and measure Ca solubility using an in vitro approach. The amounts of soluble Ca in composed dishes were consistent with the sum of soluble Ca from ingredients (three out of five meals) or higher. Among whole-wheat products, bread showed higher Ca accessibility (71%, PA/Ca = 1.1) than biscuits (23%, PA/Ca = 0.9) and pasta (15%, PA/Ca = 1.5), and among Ca-rich ingredients, semi-skimmed milk displayed higher Ca accessibility (64%) than sliced cheese (50%) and Parmesan (38%). No significant correlation between the PA/Ca ratio and Ca accessibility was found (P = 0.077). The reliability of the PA/Ca ratio for predicting the availability of calcium in composed dishes is unsatisfactory; data emphasized the importance of the overall food matrix influence on mineral accessibility. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Full Text Available Previous research investigating the relationship between parents’ and children’s diets has focused on single foods or nutrients, and not on global diet, which may be more important for good health. The aim of the study was to investigate the relationship between parental diet quality and child dietary patterns. A cross-sectional survey was conducted in 17 primary schools in Dunedin, New Zealand. Information on food consumption and related factors in children and their primary caregiver/parent were collected. Principal component analysis (PCA was used to investigate dietary patterns in children and diet quality index (DQI scores were calculated in parents. Relationships between parental DQI and child dietary patterns were examined in 401 child-parent pairs using mixed regression models. PCA generated two patterns; ‘Fruit and Vegetables’ and ‘Snacks’. A one unit higher parental DQI score was associated with a 0.03SD (CI: 0.02, 0.04 lower child ‘Snacks’ score. There was no significant relationship between ‘Fruit and Vegetables’ score and parental diet quality. Higher parental diet quality was associated with a lower dietary pattern score in children that was characterised by a lower consumption frequency of confectionery, chocolate, cakes, biscuits and savoury snacks. These results highlight the importance of parental modelling, in terms of their dietary choices, on the diet of children.

Full Text Available A gluten-free diet (GFD is currently the only available treatment for patients with celiac disease (CD. Several clinical trials have demonstrated that most celiac patients can tolerate a medium-high quantity of oats without any negative clinical effects; however, the inclusion of oats in GFD is still a matter of debate. In this study, Italian children with CD were enrolled in a 15-month, randomized, double-blind, placebo-controlled multicenter trial. Participants were randomized in two groups following either A-B treatment (6 months of diet “A”, 3 months of standard GFD, 6 months of diet “B”, or B-A treatment (6 months of diet “B”, 3 months of standard GFD, 6 months of diet “A”. A and B diets included gluten-free (GF products (flour, pasta, biscuits, cakes and crisp toasts with either purified oats or placebo. Clinical data (Gastrointestinal Symptoms Rate Scale [GSRS] score and intestinal permeability tests (IPT, were measured through the study period. Although the study is still blinded, no significant differences were found in GSRS score or the urinary lactulose/mannitol (L/M ratio between the two groups after 6 months of treatment. These preliminary results suggest that the addition of non-contaminated oats from selected varieties in the treatment of children with CD does not determine changes in intestinal permeability and gastrointestinal symptoms.

Panel data from 80 UK consumers purchasing 9 product categories (i.e., baked beans, biscuits, breakfast cereals, butter, cheese, fruit juice, instant coffee, margarine and tea) during a 16-week period were used. Elasticity coefficients were calculated for individual consumers with data from all or only 1 product category (intra-consumer elasticities), and for each product category using all data points from all consumers (overall product elasticity) or 1 average data point per consumer (interconsumer elasticity). In addition to this, split-sample elasticity coefficients were obtained for each individual with data from all product categories purchased during weeks 1 to 8 and 9 to 16. The results suggest that: 1) demand elasticity coefficients calculated for individual consumers purchasing supermarket food products are compatible with predictions from economic theory and behavioral economics; 2) overall product elasticities, typically employed in marketing and econometric research, include effects of interconsumer and intraconsumer elasticities; 3) when comparing demand elasticities of different product categories, group and individual analyses yield similar trends; and 4) individual differences in demand elasticity are relatively consistent across time, but do not seem to be consistent across products. These results demonstrate the theoretical, methodological, and managerial relevance of investigating the behavior of individual consumers.

In a previous case-control study, we demonstrated that children with PKU and non-PKU controls preferred sweet foods. Additionally, children with PKU exhibited food neophobia, with no preference for bitter tasting foods associated with the taste of phenylalanine (Phe)-free L-amino acid supplements. In an observational extension study, we evaluated the influence of parental food choice and neophobia on their children's taste preferences and food neophobia. Male and female parents/caregivers of 35 children with PKU and 35 control parents, completed a neophobia and food frequency questionnaire for comparison using the same questionnaires that they completed for their children. Both groups of children (PKU and non PKU control) were rated as more food neophobic and exhibited more neophobic behaviour than parents, although children with PKU more so than non-PKU controls (PKU food neophobia p foods such as bread and pasta, and more sweet snacks such as biscuits than their parents. Non-PKU control children's food choices were closer to their parent's choices. In PKU, parental food choices and their food neophobia have limited influence on their children's eating habits. Food neophobia in children with PKU may be associated with fear of eating unfamiliar foods potentially containing a source of protein or aspartame. Their preference for sweet foods may be influenced by limited food choices and habitual consumption of artificially sweetened L-amino acid supplements.

Adequate nutrition during complementary feeding is important for the growth, development and well-being of children. We aim to examine the energy and macronutrient intake composition and their main food sources in a mother–offspring cohort study in Singapore. The diets of infants were assessed by 24 h dietary recalls or food diaries collected from mothers when their offspring were 6 (n = 760), 9 (n = 893) and 12 (n = 907) months of age. Food sources of energy and macronutrients were determined using the population proportion methodology. Energy intakes per day (kcal; mean (standard deviation, SD)) of these infants were 640 (158) at 6 months, 675 (173) at 9 months, and 761 (208) at 12 months. Infant formula, breastmilk and infant cereals were the top three food sources of energy and macronutrient intakes in infants through the period 6 to 12 months. Other main energy and carbohydrate sources at 9 and 12 months of age were rice porridge, infant biscuits and fresh fruits, while fish, red meat and eggs were the other main protein and total fat sources. Breast-fed and mixed-fed infants had a more varied diet as compared to formula-fed infants. Formula-fed infants had consistently higher protein and lower total fat consumption compared to those who were breastfed. An understanding of these main food sources during complementary feeding can inform local dietary recommendations and policies. PMID:29534442

The purpose of this novel study was to evaluate the food environment at a Brazilian university, encompassing 6 restaurants and 13 snack bars. The investigation uniquely analyses the food environment (barriers, facilitators, type of foods and prices). This was a food-based analysis of the nutritional quality of the products sold on campus. A cross-sectional descriptive design was used, applying the classic Nutrition Environment Measures Survey-Restaurants (NEMS-R) adapted for Brazil and an original methodology to evaluate and classify qualitatively the nutritional quality and characteristics of the food. A census of all campus food environments was applied. The main results show most food and beverage products were made with processed ingredients and had a lower nutritional quality and price when compared with similar products made on premises, that is, processed iced tea compared with fresh tea ( p flour salgados compared with baked wholegrain flour salgados ( p flour biscuits compared with those made with whole grains ( p = .028). Only 16% of the outlets provided food ingredients or nutritional information of products available. The overall options for healthy food choices and good nutritional quality on campus were mostly limited by the availability and higher prices of products. These findings could be used to develop new policy perspectives for the offering of healthy food items and to facilitate better food choices among students in a healthier food environment.

Full Text Available Background & aim: Early feeding after cesarean section can have beneficial effects, however, no sufficient study has been conducted in this area. The aim of this study was to determine the effects of early feeding on the gastrointestinal complications in women after cesarean section and comparing it with a regular diet.   Methods: The present randomized-clinical-trial study was conducted on 160 women who admitted to Shohada hospital and underwent cesarean section in 2011-2012. The inclusion criteria included women with gestational age more than 37 weeks, singleton pregnancy, having at least 8 hours of fasting, and regional anesthesia (spinal cord, respectively. After registration of demographic characteristics and pregnancy, women were randomly divided into two groups: Early feeding (2 hours after completion of the operation, 250 ml filtered juice, tea and biscuits style regime in the next 2 hours and 2 hours after the usual diet and the usual power (8 hours of operation clear liquid diet the day after the usual diet groups. Presence of gastrointestinal symptoms in 2, 4, 8 and 12 hours after surgery, time to the bowel sounds auscultation, passage of flatus and stool were recorded. Data were analyzed by SPSS software version13.The significance level of p-value was considered 0.05.   Conclusion: Early feeding caused the acceleration of gastrointestinal symptoms, earlier bowel sounds auscultation and earlier utilization of gas. It is recommended to investigate the different diets and examined the level of compliance and satisfaction.

The definition of fat differs in different countries; thus whether fat is listed on food labels depends on the country. Some countries list crude fat content in the 'Fat' section on the food label, whereas other countries list total fat. In this study, three methods were used for determining fat classes and content in bakery products: the Folch method, the automated Soxhlet method, and the AOAC 996.06 method. The results using these methods were compared. Fat (crude) extracted by the Folch and Soxhlet methods was gravimetrically determined and assessed by fat class using capillary gas chromatography (GC). In most samples, fat (total) content determined by the AOAC 996.06 method was lower than the fat (crude) content determined by the Folch or automated Soxhlet methods. Furthermore, monounsaturated fat or saturated fat content determined by the AOAC 996.06 method was lowest. Almost no difference was observed between fat (crude) content determined by the Folch method and that determined by the automated Soxhlet method for nearly all samples. In three samples (wheat biscuits, butter cookies-1, and chocolate chip cookies), monounsaturated fat, saturated fat, and trans fat content obtained by the automated Soxhlet method was higher than that obtained by the Folch method. The polyunsaturated fat content obtained by the automated Soxhlet method was not higher than that obtained by the Folch method in any sample. Copyright © 2012 Elsevier Ltd. All rights reserved.

2013-01-01

Background To determine the portion sizes of traditional and non-traditional foods being consumed by Inuit adults in three remote communities in Nunavut, Canada. Methods A cross-sectional study was carried out between June and October, 2008. Trained field workers collected dietary data using a culturally appropriate, validated quantitative food frequency questionnaire (QFFQ) developed specifically for the study population. Results Caribou, muktuk (whale blubber and skin) and Arctic char (salmon family), were the most commonly consumed traditional foods; mean portion sizes for traditional foods ranged from 10 g for fermented seal fat to 424 g for fried caribou. Fried bannock and white bread were consumed by >85% of participants; mean portion sizes for these foods were 189 g and 70 g, respectively. Sugar-sweetened beverages and energy-dense, nutrient-poor foods were also widely consumed. Mean portion sizes for regular pop and sweetened juices with added sugar were 663 g and 572 g, respectively. Mean portion sizes for potato chips, pilot biscuits, cakes, chocolate and cookies were 59 g, 59 g, 106 g, 59 g, and 46 g, respectively. Conclusions The present study provides further evidence of the nutrition transition that is occurring among Inuit in the Canadian Arctic. It also highlights a number of foods and beverages that could be targeted in future nutritional intervention programs aimed at obesity and diet-related chronic disease prevention in these and other Inuit communities.

Full Text Available Background: A child’s optimal growth can be indicated by many factors, among them is body height, therefore stunting is one of the evidences of undergrowth. Nutrition, on the other hand, is one of variables affecting growth. This study aimed to examine the nutrition intake, in the form of energy, carbohydrate, protein, and fat in stunted children aged 3–5 years in Jatinangor. Methods: This cross sectional study was carried out in September to October 2014 using the random sampling method. Dietary data from 70 stunted children aged 3–5 years in pre–school and kindegarten located in 9 urban areas in Jatinangor were collected through 3x24 Recall and Food Frequency Questionaire and analyzed. Results: Mean energy intake was 1113.6 kcal and mean carbohydrate intake was 137.4 grams. Mean protein intake was 38.4 gram and mean fat intake was 38.2 gram. Types of food highly consumed as the source of carbohydrate were white rice and biscuit, and as the source of protein were meatball, sausage, and egg. Highest consumed vegetables, fruits and snack were water spinach, cabbage, watermelon, banana, and milk respectively. Conclusions: Mean energy intake, mean carbohydrate intake, and mean fat intake are all below the recommended dietary allowance (RDA 2013 with individual value of mean energy intake is below RDA 2013 for all subjects. Mean protein intake is slightly above RDA 2013.

Insects have long been consumed as part of the diets of many Asian, African, and South American cultures. However, despite international agencies such as the Food and Agriculture Organization of the United Nations advocating the nutritional, environmental, and economic benefits of entomophagy, attitudinal barriers persist in Western societies. In Australia, the indigenous ‘bush tucker’ diet comprising witchetty grubs, honey ants, and Bogong moths is quite well known; however, in most Australian locales, the consumption of insects tends to occur only as a novelty. Therefore, this study aimed to investigate the awareness and acceptance of insects as food. An online survey of 820 consumers found that 68% of participants had heard of entomophagy, but only 21% had previously eaten insects; witchetty grubs, ants, grasshoppers, and crickets were the most commonly tasted insects. Taste, appearance, safety, and quality were identified as the factors that were most likely to influence consumer willingness to try eating insects, but consumer attitudes towards entomophagy were underpinned by both food neophobia (i.e., reluctance to eat new or novel foods) and prior consumption of insects. Neophobic consumers were far less accepting of entomophagy than neophilic consumers, while consumers who had previously eaten insects were most accepting of insects as food. Incorporating insects into familiar products (e.g., biscuits) or cooked meals also improved their appeal. Collectively, these findings can be used by the food industry to devise production and/or marketing strategies that overcome barriers to insect consumption in Australia.

[Global trends in food consumption and nutrition].

Obesity and lifestyle diseases increase all over the world, especially in developing countries. One reason is the change in diet. This nutrition transition is characterised by improvement in dietary variation, but also by increase in the content of fat and sugar. The transition seems to start at a lower level of income, compared to what occurred in the Western countries after the Second World War. The reason is that many foods are relatively cheaper, especially fat and sugar. The world market is presently flooded with cheap vegetable fat. Urbanisation leads to over-consumption by increasing market access to fatty and sugary foods, including fast foods. Globalization increases the consumption of sweet soda pops, biscuits and snacks produced by multinational companies. Western supermarkets and fast food franchises also promote these dietary changes (McDonaldization). It has been proposed that the population in developing countries is more vulnerable towards these dietary changes in regard to obesity and chronic diseases, due to undernutrition in early life (the Barker hypothesis). We may therefore expect an unprecedented increase in the prevalence of chronic diseases, especially diabetes type 2 in the developing countries. One may question if this increase will be a transient phenomenon, or if we can expect the same pattern as we have seen in the West, namely that the poor become the fat-test segment of the population, with the highest prevalence of chronic diseases.

Two independent cross-sectional dietary surveys (the Individual and National Food Consumption Surveys, INCA), performed in 1998-99 (INCA1) and in 2006-07 (INCA2) on nationally representative samples of French people, were used to analyse trends in the dietary habits and nutritional intake of French adults. Food consumption was recorded through 7-d dietary records, and nutritional intakes were assessed using the French food composition database. After exclusion of under-reporters, analyses were performed on 3267 adults, aged 18-79 years: 1345 from INCA1 and 1922 from INCA2. The trends highlighted over the 8-year period showed a decrease in consumption of dairy products, meat, bread, potatoes, pastries/croissant-like pastries/cakes/biscuits and sugar/confectionery. In contrast, the consumption of fruits and vegetables, rice, ice cream and chocolate increased. Other food groups, like fish and snacking foods, remained stable. Food choices were mostly age specific. These age differences remained consistent over the years and underlined two opposite dietary trends: a 'traditional' one mainly followed by the elderly, and a 'snacking and convenience' one mainly adopted by young adults. The overall trends in food consumption did not influence the mean energy intake, but did slightly modify the contribution of each macronutrient to energy intake. These repeated surveys highlighted the fact that trends in French food habits have moved towards an average European diet at the crossroads between Mediterranean and Northern diets, and that food consumption changes impacted, to a lesser extent, nutritional intake.

Full Text Available Background: To our knowledge no study has focused on the pattern of cereal-based products (CBP consumption among people with celiac disease (CD. Our study aimed at evaluating the dietary intake of CBP among patients with CD and comparing it with a control population. Methods: Eighty-two volunteers with CD and 77 non-CD volunteers enrolled throughout Italy were asked to register their consumption of CBP on specific diaries for three days. Results: CD patients’ median three-day intake of biscuits and crackers was higher compared to controls (65.8 g vs. 22.7 g and 44.7 g vs. 10.6 g, p < 0.05 respectively, Mann–Whitney test. A significant difference was observed also comparing the two groups for median three-day bread consumption, with the CD group consuming less bread than controls (109.5 g vs. 150.7 g, p < 0.05, Mann–Whitney test. When assessing regional and gender-related CBP consumption patterns, significantly higher rice consumption was found among CD women from Northern Italy compared to CD women from Central and Southern Italy (p = 0.006 and p = 0.002 respectively, Fisher’s exact test. No other significant differences were observed. Conclusions: Our results provide a snapshot of the overall consumption of CBP among Italian subjects with CD. Altogether, these data show that, despite minor differences, dietary consumption of CBP among CD patients is similar to the general population.

A total of 290 individual food samples were collected in Hong Kong, China, for 3-monochloropropane-1,2-diol (3-MCPD) fatty acid esters analysis. Most samples were processed food and in ready-to-eat form. The results show that the levels of 3-MCPD fatty acid esters were high in biscuits, fats and oils, snacks and Chinese pastry with mean bound 3-MCPD levels of 440, 390, 270 and 270 μg kg⁻¹, respectively. The dietary exposures to bound 3-MCPD of average and high adult consumers were estimated to be 0.20 and 0.53 μg kg bw⁻¹ day⁻¹, respectively. The primary toxicological concern of 3-MCPD fatty acid esters is its potential to release 3-MCPD in vivo during digestion in the gastrointestinal tract. 3-MCPD would affect the kidney, the central nervous system and the male reproductive system of rats. Assuming that 100% of the 3-MCPD was released from 3-MCPD fatty acid esters by hydrolysis in the digestive system, the dietary exposures to 3-MCPD for average and high adult consumers were only 10% and 26% of the provisional maximum tolerable daily intake (PMTDI) of 3-MCPD established by the Joint Food and Agriculture Organization/World Health Organization Expert Committee on Food Additives (JECFA) (2 μg kg bw⁻¹ day⁻¹), respectively. The results suggest that both average and high adult consumers are unlikely to experience major toxicological effects of 3-MCPD.

Wildfire is becoming the focus of increasing attention with heightened concerns related to climate change, global warming, and safety in the urban-wildland interface. One aspect of wildfire behavior has been totally overlooked until recently—the role of pyrocumulonimbus (pyroCb for short) in both firestorm dynamics and atmospheric impact. PyroCb are fire-started or -augmented thunderstorms that in their most extreme manifestation inject huge abundances of smoke and other biomass burning emissions into the lower stratosphere. The observed hemispheric spread of smoke and other biomass burning emissions could have important climate consequences. Such an extreme injection by thunderstorms was previously judged to be impossible because the extratopical tropopause is considered to be an effective lid on convection. At least two recurring themes have developed as pyroCb research unfolds. First, some "mystery layer" events—puzzling stratospheric aerosol layer observations— and layers reported as volcanic aerosol can now be explained in terms of pyroconvection as the "smoking gun." Secondly, pyroCb events occur with surprising frequency, and they are likely a relevant aspect of several historic wildfires. Here we will show that pyroCbs offer an alternative explanation for previously assumed volcanic aerosols in 1989-1991. In addition, we survey the Canada/USA fire season of 2002 and identify 17 pyroCbs, some of which are associated with newsworthy fires such as Hayman, Rodeo/Chediski, and Biscuit fires. Several of these pyroCbs injected smoke into the lowermost stratosphere.

Full Text Available Adequate nutrition during complementary feeding is important for the growth, development and well-being of children. We aim to examine the energy and macronutrient intake composition and their main food sources in a mother–offspring cohort study in Singapore. The diets of infants were assessed by 24 h dietary recalls or food diaries collected from mothers when their offspring were 6 (n = 760, 9 (n = 893 and 12 (n = 907 months of age. Food sources of energy and macronutrients were determined using the population proportion methodology. Energy intakes per day (kcal; mean (standard deviation, SD of these infants were 640 (158 at 6 months, 675 (173 at 9 months, and 761 (208 at 12 months. Infant formula, breastmilk and infant cereals were the top three food sources of energy and macronutrient intakes in infants through the period 6 to 12 months. Other main energy and carbohydrate sources at 9 and 12 months of age were rice porridge, infant biscuits and fresh fruits, while fish, red meat and eggs were the other main protein and total fat sources. Breast-fed and mixed-fed infants had a more varied diet as compared to formula-fed infants. Formula-fed infants had consistently higher protein and lower total fat consumption compared to those who were breastfed. An understanding of these main food sources during complementary feeding can inform local dietary recommendations and policies.

Intake of antioxidants, dietary fiber, and protein, had been known to reduce plasma glucose level. Objective: To evaluate the effect of composite flour diet on plasma glucose levels, body weight and food consumption of streptozotocin (STZ-diabetic rats. Method: Thirty male Sprague-Dawley rats aged ± 2 months (± 200 grams, were divided into three groups of ten rats. They were (1 non-diabetic standard diet (ND-STD, (2 diabetic (65 mg/kg of body weight by STZ induction standard diet (D-STD, and (3 diabetic composite flour diet (1,5 g/100 g of body weight/day (D-CFD, for 4 weeks, 3 days after STZ induction. The plasma glucose obtained from GOD-PAP method were determined before induction, after induction and every week during diet intervention. Results: Plasma glucose levels was significantly lower in D-CFD when compared with D-STD (p<0,05. The weight of D-STD was found to be significantly decreased as compared to ND-STD (p<0,05. There were no changes in food consumption of ND-STD, D-STD and D-CFD (p<0,05. Conclusion: The composite flour could reduce plasma glucose level in diabetic rats and did not give negative effects on body weight and food consumption.

Australian Consumers’ Awareness and Acceptance of Insects as Food

Full Text Available Insects have long been consumed as part of the diets of many Asian, African, and South American cultures. However, despite international agencies such as the Food and Agriculture Organization of the United Nations advocating the nutritional, environmental, and economic benefits of entomophagy, attitudinal barriers persist in Western societies. In Australia, the indigenous ‘bush tucker’ diet comprising witchetty grubs, honey ants, and Bogong moths is quite well known; however, in most Australian locales, the consumption of insects tends to occur only as a novelty. Therefore, this study aimed to investigate the awareness and acceptance of insects as food. An online survey of 820 consumers found that 68% of participants had heard of entomophagy, but only 21% had previously eaten insects; witchetty grubs, ants, grasshoppers, and crickets were the most commonly tasted insects. Taste, appearance, safety, and quality were identified as the factors that were most likely to influence consumer willingness to try eating insects, but consumer attitudes towards entomophagy were underpinned by both food neophobia (i.e., reluctance to eat new or novel foods and prior consumption of insects. Neophobic consumers were far less accepting of entomophagy than neophilic consumers, while consumers who had previously eaten insects were most accepting of insects as food. Incorporating insects into familiar products (e.g., biscuits or cooked meals also improved their appeal. Collectively, these findings can be used by the food industry to devise production and/or marketing strategies that overcome barriers to insect consumption in Australia.

Immigrants in Sweden have on average poorer health than native Swedes, including the risk of nutritional problems. In Sweden's multicultural society there is a need for increased knowledge about eating habits in public health work within health and education. A survey of refugees from Bosnia-Herzegovina living in Sweden was undertaken to describe the choice of food and food traditions in pre-war Bosnia. The purpose was to introduce the subject of food, health and migration into public health work and develop culture-adapted food and health advice. Focus-group interviews were undertaken with a total of 20 women refugees from Bosnia-Herzegovina. Qualitative data analysis identified a large consumption of bread as a staple food with meat, vegetables, milk, cheese, legumes, egg and fish as additions. Self-sufficiency was noted with milk souring, jam making and the production of sweet fruit drinks. Home made cheese and drying or smoking of meat were common methods of food storage. In child rearing, breast-feeding for 6-8 months was most common. Home made breast milk replacements were made from semolina, rice and 'petit biscuits'. Several important factors need to be taken into account when giving culturally adapted food and health advice to Bosnian families, such as encouraging bread, vegetable and legume consumption and giving advice on substituting sweet fruit drinks for natural fruit. One should be conscious of how religious beliefs as well as socio-cultural, historical, ecological, economical and psychological influences may guide food choices.

Wholegrain grains and cereals contain a wide range of potentially protective factors that are relevant to gastrointestinal health. The prebiotics best studied are fructans [fructooligosaccharides (FOS), inulin] and galactooligosaccharides (GOS). These and other short-chain carbohydrates can also be poorly absorbed in the small intestine (named fermentable oligo-, di- and monosaccharides and polyols; FODMAPs) and may have important implications for the health of the gut. In the present study, FODMAPs, including fructose in excess of glucose, FOS (nystose, kestose), GOS (raffinose, stachyose) and sugar polyols (sorbitol, mannitol), were quantified using high-performance liquid chromatography with an evaporative light scattering detector. Total fructan was quantified using an enzymic hydrolysis method. Fifty-five commonly consumed grains, breakfast cereals, breads, pulses and biscuits were analysed. Total fructan were the most common short-chain carbohydrate present in cereal grain products and ranged (g per portion as eaten) from 1.12 g in couscous to 0 g in rice; 0.6 g in dark rye bread to 0.07 g in spelt bread; 0.96 g in wheat-free muesli to 0.11 g in oats; and 0.81 g in muesli fruit bar to 0.05 g in potato chips. Raffinose and stachyose were most common in pulses.   Composition tables including FODMAPs and prebiotics (FOS and GOS) that are naturally present in food will greatly assist research aimed at understanding their physiological role in the gut. © 2011 The Authors.

The glycaemic response of millet foods and the effect of processing are not known. Therefore, decorticated proso millet was used to produce four types of common food products (biscuits, couscous, porridge and an extruded snack). Postprandial blood glucose response of these products (all containing 50 g of total starch) was compared to the same foods produced with refined corn, in a crossover human study with 12 healthy male participants (age 26.3 ± 3.8 yr; BMI 23.3 ± 2.8 kg/m 2 ). Capillary blood samples were collected and glycaemic response was determined; differences were assessed using repeat measures ANOVA. Overall, the mean (±SEM) incremental area under the blood glucose response curve (mmol min/l) of the proso millet products was different from the corn products, but individual products (couscous = 66.7 ± 11.6, biscuit = 82.6 ± 13.7, extrudate = 198.7 ± 20.9, porridge = 40.1 ± 5.8) were not significantly lower (couscous = 43.5 ± 5.8, biscuit = 102.0 ± 10.3, extrudate = 198.7 ± 20.9, porridge = 52.2 ± 8.1) (p > .05). Glycaemic response of the products was not dependent on the grain type, but rather product matrix.

To examine the effects of ASD diagnosis and motor skills on socialization in young children. Two samples were used: gross motor skills sample (n = 408) and fine motor skills sample (n = 402). The Battelle Developmental Inventory-Second Edition assessed motor skills, while the Baby and Infant Screen for Children with aUtIsm Traits, Part 1 assessed socialization. A main effect of diagnosis was found for both samples on socialization such that those with autism exhibited the most severe deficits followed by those with PDD-NOS and then atypically developing children. There was a main effect for gross motor skills, with high gross motor skills showing less social impairment. The interaction term was only significant in regards to fine motor skills. The individual effects of ASD diagnosis and motor impairment as well as the interaction have implications for the assessment and treatment in these individuals.

The many differences between cookie- and cracker-baking are discussed and described in terms of the functionality, and functional requirements, of the major biscuit ingredients--flour and sugar. Both types of products are similar in their major ingredients, but different in their formulas and processes. One of the most important and consequential differences between traditional cracker and cookie formulas is sugar (i.e., sucrose) concentration: usually lower than 30% in a typical cracker formula and higher than 30% in a typical cookie formula. Gluten development is facilitated in lower-sugar cracker doughs during mixing and sheeting; this is a critical factor linked to baked-cracker quality. Therefore, soft wheat flours with greater gluten quality and strength are typically preferred for cracker production. In contrast, the concentrated aqueous sugar solutions existing in high-sugar cookie doughs generally act as an antiplasticizer, compared with water alone, so gluten development during dough mixing and starch gelatinization/pasting during baking are delayed or prevented in most cookie systems. Traditional cookies and crackers are low-moisture baked goods, which are desirably made from flours with low water absorption [low water-holding capacity (WHC)], and low levels of damaged starch and water-soluble pentosans (i.e., water-accessible arabinoxylans). Rheological (e.g., alveography) and baking tests are often used to evaluate flour quality for baked-goods applications, but the solvent retention capacity (SRC) method (AACC 56-11) is a better diagnostic tool for predicting the functional contribution of each individual flour functional component, as well as the overall functionality of flours for cookie- and/or cracker-baking.

The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

The glycemic index (GI) and glycemic load (GL) are useful parameters in the nutritional classification of carbohydrate foods. Diets characterized by a low GI and/or a low GL have been repeatedly and independently associated with decreased risk of diabetes and other chronic diseases. The aim of this study is to report the GI and GL value of carbohydrate-rich foods available on the Italian market and mostly consumed in Italy. GI values were determined according to FAO/WHO (1997) and ISO (2010). Overall, the 141 commercial foods that were analyzed represent food categories that are the source of >80% carbohydrate intake in Italy. The food items chosen were based mainly on the market share of the brand within each food category and grouped into 13 food categories: 1) beverages: fermented milk drink, juice, smoothie, soft drink; 2) biscuits; 3) breads; 4) bread substitutes; 5) breakfast cereals; 6) cakes and snacks; 7) candy and confectionery; 8) cereals; 9) desserts and ice-creams; 10) marmalade and jam; 11) pasta; 12) pizza; 13) sugar and sweetener. This database of commercial Italian foods partly overcomes the lack of information on GI and GL of local foods, contributing to a better understanding of the association between GI/GL and health and providing a more informed choice to Italian consumers and health practitioners.

Full Text Available Dietary behaviour is an important modifiable factor in cardiovascular disease (CVD prevention. The study aimed to identify dietary patterns (DPs and explore their association with CVD incidence and risk markers. A follow-up of 1838 middle-aged men, aged 47–67 years recruited into the Caerphilly Prospective Cohort Study at phase 2 (1984–1988 was undertaken. Principal component analysis identified three DPs at baseline, which explained 24.8% of the total variance of food intake. DP1, characterised by higher intakes of white bread, butter, lard, chips and sugar-sweetened beverages and lower intake of wholegrain bread, was associated with higher CVD (HR 1.35: 95% CI: 1.10, 1.67 and stroke (HR 1.77; 95% CI: 1.18, 2.63 incidence. DP3, characterised by higher intakes of sweet puddings and biscuits, wholegrain breakfast cereals and dairy (excluding cheese and butter and lower alcohol intake, was associated with lower CVD (HR 0.76; 95% CI: 0.62, 0.93, coronary heart disease (HR: 0.68; 95% CI: 0.52, 0.90 and stroke (HR: 0.68; 95% CI: 0.47, 0.99 incidence and a beneficial CVD profile at baseline, while DP1 with an unfavourable profile, showed no clear associations after 12 years follow-up. Dietary pattern 2 (DP2, characterised by higher intake of pulses, fish, poultry, processed/red meat, rice, pasta and vegetables, was not associated with the aforementioned outcomes. These data may provide insight for development of public health initiatives focussing on feasible changes in dietary habits.

To assess the prevalence of dysphagia and its typical findings in unselected "real-world" Parkinson patients using an objective gold-standard method. This was a prospective, controlled, cross-sectional study conducted in 119 consecutive Parkinson patients of all stages independent of subjective dysphagia. Patients and 32 controls were clinically and endoscopically examined by flexible endoscopic evaluation of swallowing (FEES) to evaluate the deglutition with regard to three consistencies (water, biscuit, and bread). Typical findings of dysphagia like penetration and aspiration, residues, and leakage were assessed. Dysphagia was common in Parkinson patients and occurred in all, even early, disease stages. Only 5% (6/119) of patients showed a completely unremarkable deglutition. Aspiration was seen in 25% (30/119) of patients and always related to water. Residues occurred in 93% (111/119), most commonly for bread. Leakage was much less frequent and was found in only 3-18%, depending on consistency. In a significant fraction of patients, objective dysphagia was not subjectively perceived. A total of 16% of asymptomatic patients suffered from critical aspiration. Significant swallowing deficiencies already occurred in early disease. Aspiration was found in 4 of 20 (20%) patients with disease duration of less than 2 years. Seven of 57 patients (12%) with Hoehn and Yahr stage 2 suffered from severe aspiration. Given the high frequency of critical aspiration in Parkinson disease, these patients should be evaluated early for dysphagia to avoid complications and recommend an adequate therapy. FEES is a simple, cost efficient, minimally invasive method that is ideally suited for this purpose.

A school environment that encourages students to opt for food with sound nutritional value is both essential and formative in ensuring that young people adopt healthy eating habits. The aim of this paper is to describe the food offered for lunch in the cafeteria service lines in Quebec schools on regular school days. A cross-sectional survey was conducted between November 2008 and June 2009 with a representative sample of 207 French-speaking schools in the province of Quebec. The response rate was 71%. The cafeteria food available from the service line was observed directly and systematically by research assistants trained in observational procedures. Bivariate and descriptive analyses were performed. While most schools offered a vegetable side dish, only 71% of primary schools, 71% of public secondary schools, and 54% of private secondary schools did not offer cold-cut dishes, stuffed pastry, or a fried food on their daily menus. The sandwiches available were rarely made with whole-grain bread. Public secondary schools had more cookies, biscuits, muffins, and chewing gum than private primary and secondary schools. Milk was available in 85% of the primary schools. Most of the schools had eliminated sodas but were still offering fruit cocktails instead of 100% fruit juice. The school eating environment changed significantly from 2002 to 2009, presumably as a result of the government action plan and the Framework Policy. Improvements must be made with respect to reducing added sugar in beverages and desserts and promoting baked rather than fried snacks. Vigilance is required since many new products are making their way into the market.

In order to investigate the bone density of freshmen, and to analyze the association between dietary pattern and bone mineral density (BMD). A questionnaire survey on the situation of dietary pattern was conducted in 1414 freshmen. Effective dietary survey questionnaires and bone mineral density measurements were completed for 1319 participants. Bone mass was assessed by using an Ultrasound Bone Densitometer on the right calcaneus (CM-200, Furuno Electric Corporation, Japan), and the speed of sound (SOS, m/s) was used as an indicator for bone density. Factor analysis with varimax rotation was used to identify the dietary patterns. After adjusting for confounders, covariance with Bonferroni's was used to further examine the associations between dietary patterns and bone mineral density (BMD). (1) Four major dietary patterns were noticed. Western food pattern (high consumption in hamburger, fried food, nuts, biscuit, chocolate, cola, coffee, sugars). Animal protein pattern (high consumption in pork, mutton, beef, poultry meat, animal liver). Calcium pattern (high consumption in fresh fruits, eggs, fish and shrimps, kelp laver and sea fish, milk and dairy products, beans and bean products). Traditional Chinese pattern (high consumption in rice and grain, fresh fruits, fresh vegetables, pork). (2) No association was observed between the western food pattern and bone mineral density. High animal protein pattern showed lower SOS value compared with low animal protein pattern. High calcium pattern showed higher SOS value compared with low calcium pattern. High traditional Chinese pattern showed higher SOS value compared with the low traditional Chinese pattern. Dietary patterns are closely related with bone mineral density (BMD) of freshmen.

To establish a Market Basket of Sao Paulo state seventy-one foods, with a mean consumption of more than 2 g day -1 per person, were grouped into 30 food categories. The food groups were: cereals, leguminous, leafy vegetables, fruity vegetables, tuberous vegetables, tropical fruits, other fruits, flours, pastas, breads, biscuits, prime grade beef, standard grade beef, pork meats, other meats, poultry, milk/cream, other dairy products, sugars, sweets, salts, sauces, oils, fats, alcoholic beverages, non-alcoholic beverages, coffee, ready-made dishes, saltwater and freshwater fishes. Information about individual food consumption was obtained from a recent national household food budget survey 'POF 2002-2003' conducted by the Brazilian Institute for Geography and Statistics from July 2002 to June 2003. Sampling and kitchen preparation of foods were carried out in restaurants of the University of Sao Paulo. Each food item was individually prepared table-ready. Foods of the same group were mixed, homogenized, pulverized and analyzed for the determination of Ca, Cr, Fe, K, Na and Zn concentrations by Instrumental Neutron Activation Analysis. Average daily intake of each element was calculated by multiplying the element concentration in the food by the corresponding weight of the ready-to-consume food group. The contribution of each food group to the total daily intake of elements by the ready-to-consume food groups of the Market Basket was evaluated. The food groups representing the highest contributions were salts: 79% Na; breads: 37% Fe and 46% Cr; cereals: 19% Zn and milk/cream: 58% Ca and 24% K. (author)

Genetic variation in the fat mass and obesity-associated gene (FTO in association with food preferences in healthy adults

Louise Brunkwall

2013-04-01

Full Text Available Background: Earlier studies have indicated that the fat mass and obesity-associated gene (FTO is not only associated with BMI and weight but also with appetite and dietary intake. Objectives: We investigated if the FTO rs9939609 associates with food preferences in healthy adults with no cancer, cardiovascular disease, or diabetes. Additionally, we challenged the question if the associations are modified by obesity status (BMI ≤25 or >25 kg/m2. Design: The analyses are made with 22,799 individuals from the Swedish population-based Malmö Diet and Cancer Cohort Study, who were born between 1923 and 1945. To investigate food preference, 27 food groups conducted from a modified diet history method including a 7-day registration of cooked meals and cold beverages were used in the analyses. Bonferroni correction was used to correct for multiple testing, resulting in a cut-off value for significance level of p<0.002. Results: We observed that the obesity susceptible A-allele carriers reported a higher consumption of biscuits and pastry but lower consumption of soft drinks (P for trend <0.0001 for both as compared to TT genotype carriers. In contrast to our hypothesis, the results did not significantly differ depending on obesity status except for consumption of juice, where only the overweight individuals with A-allele had a higher consumption as compared to TT carriers (P for interaction=0.04. Conclusion: Our results indicate that the FTO A-allele may associate with certain food preference and in particular with certain energy-dense foods.

The aim of the present study was to determine the behavioural effects of the selective dopamine D1 receptor agonist, SKF 38393, and of the selective dopamine D2/D3 receptor agonist, quinpirole, on the feeding performance of food-deprived rats in a model of food-preference behaviour. The animals were familiarised with a choice between a high-palatability, high-fat, high-sugar food (chocolate biscuits/cookies) and their regular maintenance diet. Following administration of either SKF 38393 (1.0-10.0 mg/kg, s.c.) or quinpirole (0.03-0.3 mg/kg, s.c.), the animals were observed throughout a 15-min test period, and their feeding behaviour was carefully monitored. Other behavioural categories were also observed. The resulting data were subject to a microstructural analysis to determine the loci of the behavioural effects. The results indicated that SKF 38393 and quinpirole had contrasting effects on the preference for the high-palatability chocolate food. SKF 38393 enhanced the preference, whereas quinpirole eliminated it. These data reinforce the view that forebrain dopamine mechanisms are closely involved in responses to high-palatability energy-dense food constituents, including chocolate. The data also indicate that pharmacological characterization is important, such that dopamine receptor subtypes appear to mediate contrasting effects on food preference for a high-fat, high-sugar food. Hence, brain dopamine appears to be involved in potentially complex ways in determining food preferences, and this may carry implications in the growing evidence for a link between brain dopamine and human obesity.

The aim of this study was to determine the level of bound 3-monochloropropan-1,2-diol in foodstuffs commonly consumed in Hong Kong, China, by an enzymatic hydrolysis indirect method which proved to be free from interferences. A total of 290 samples were picked up randomly from the local market and analysed. About 73% of these samples were found to contain detectable amounts of bound 3-MCPD. Amongst the 73 food items, bound 3-MCPD was not detected in 13 food items, including extra virgin olive oil, beef ball/salami, beef flank, ham/Chinese ham, nuts, seeds, soy sauce, oyster sauce, butter, yoghurt, cream, cheese and milk. For those found to contain detectable bound 3-MCPD, the content ranged up to 2500 µg kg(-1). The highest mean bound 3-MCPD content among the 14 food groups was in biscuits (440 [50-860] µg kg(-1)), followed by fats and oils (390 [n.d.-2500] µg kg(-1)), snacks (270 [9-1000] µg kg(-1)), and Chinese pastry (270 [n.d.-1200] µg kg(-1)). Among the samples, the highest bound 3-MCPD content was in a grape seed oil (2500 µg kg(-1)), followed by a walnut flaky pastry (1200 µg kg(-1)) and a grilled corn (1000 µg kg(-1)). Basically, the results of this study agreed well with other published results in peer-reviewed journals, except for cheese, cream, ham, nuts and seeds.

Objectives: The European Union (EU)-funded project Food Labelling to Advance Better Education for Life (FLABEL) aims to understand how nutrition information on food labels affects consumers' dietary choices and shopping behaviour. The first phase of this study consisted of assessing the penetration of nutrition labelling and related information on various food products in all 27 EU Member States and Turkey. Methods: In each country, food products were audited in three different types of retailers to cover as many different products as possible within five food and beverage categories: sweet biscuits, breakfast cereals, pre-packed chilled ready meals, carbonated soft drinks and yoghurts. Results: More than 37 000 products were audited in a total of 84 retail stores. On average, 85% of the products contained back-of-pack (BOP) nutrition labelling or related information (from 70% in Slovenia to 97% in Ireland), versus 48% for front-of-pack (FOP) information (from 24% in Turkey to 82% in the UK). The most widespread format was the BOP tabular or linear listing of nutrition content. Guideline daily amounts labelling was the most prevalent form of FOP information, showing an average penetration of 25% across all products audited. Among categories, breakfast cereals showed the highest penetration of nutrition-related information, with 94% BOP penetration and 70% FOP penetration. Conclusions: Nutrition labelling and related information was found on a large majority of products audited. These findings provide the basis for subsequent phases of FLABEL involving attention, reading, liking, understanding and use by consumers of different nutrition labelling formats. PMID:20808336

When an infant is brought home to the family, it is often a time of emotional, economic and physical stress due to the extra demands placed on parents. Household food security means "access at all times to enough and nutritionally appropriate food to provide the energy and nutrients needed to maintain an active and healthy life". Questions about food security were asked of 1376 Pacific Island mothers (as part of the Pacific Island Family Study) approximately six weeks after the birth of their baby. Due to lack of money food sometimes ran out in 39.8% of households and in a further 3.8% food often ran out. Variety of foods was limited by lack of money in 39.3%. Foods that were still bought when money was limited included bread (97%), milk (95%), meat and chicken (91%), vegetables and fruit (83%), rice or pasta (82%), breakfast cereals (69%), fish or shellfish (50%) and biscuits or chips (44%). Alcohol (1%), soft drinks (11%), ice cream (12%) and fruit juice (21%) were the least often bought. Energy density (MJ/kg) and nutrient-density of typical foods limited by lack of money were analysed. Rice, bread and fatty meats provided the most calories per dollar and fruit and vegetables the least. The best protein-value for money was from minced beef, chicken and tinned tuna and the most fibre-rich foods included baked beans and mixed vegetables. Food security is a major problem for Pacific families. The environment of food availability, choice and cost requires attention to help close the health gap.

Little is known about adolescents' non-core food intake in the UK and the eating context in which they consume non-core foods. The present study aimed to describe types of non-core foods consumed by British adolescents in total and across different eating contexts. A descriptive analysis, using cross-sectional data from food diaries. Non-core foods were classified based on cut-off points of fat and sugar from the Australian Guide to Healthy Eating. Eating context was defined as 'where' and 'with whom' adolescents consumed each food. Percentages of non-core energy were calculated for each food group in total and across eating contexts. A combined ranking was then created to account for each food's contribution to non-core energy intake and its popularity of consumption (percentage of consumers). The UK National Diet and Nutrition Survey 2008-2011. Adolescents across the UK aged 11-18 years (n 666). Non-core food comprised 39·5 % of total energy intake and was mostly 'Regular soft drinks', 'Crisps & savoury snacks', 'Chips & potato products', 'Chocolate' and 'Biscuits'. Adolescents ate 57·0 % and 51·3 % of non-core food at 'Eateries' or with 'Friends', compared with 33·2 % and 32·1 % at 'Home' or with 'Parents'. Persistent foods consumed across eating contexts were 'Regular soft drinks' and 'Chips & potato products'. Regular soft drinks contribute the most energy and are the most popular non-core food consumed by adolescents regardless of context, and represent a good target for interventions to reduce non-core food consumption.

Seeds of the wheat variety K-68 equilibrated at 14 and 4% moisture levels were irradiated with 5,10,15, and 20Kr doses of Co 60 gamma rays. The observations in M 1 generation on germination, survival, seedling height, chromosomal aberrations and pollen and ovule sterility indicated maximum radiosensitivity at 4% seed moisture level with increasing doses. Further, in M 2 generation both mutation frequency and spectrum were much greater at 4% seed moisture level. Desirable mutants from yield point of view were identified in M 2 and stabilized in M 3 generation. Five promising mutants, out of which three were from 4% seed moisture level, along with control were grown in a randomized block design in M 4 generation. Mutant HUW-Dfl yielded highest (29.30q/ha) and HUW-DrHP3 the lowest (18.50q/ha), the control yield being 18.70q/ha. Protein values ranged from 12.57 to 16.76% for different mutants as against 12.92% for control. Mutant HUW-SDf2 had the highest lysine value (2.81%) and HYW-DfHP2 the lowest value (2.21%). There was a significant negative correlation (rsup(=)-.961) between protein and lysine. Pelsenke value ranged from 39 to 246 (min.) for different mutants in contrast to 198 (min.) for control, giving a fairly good latitude for biscuit, bread, and chapati making purposes. Findings clearly indicate that seed moisture greatly influences gamma rays induced mutations which may be attributed to maximum accumulation of long lived free radicals at 4% moisture level.

Full Text Available Abstract Background Previous research has documented a negative association between maternal report of child food neophobia and reported frequency of consumption of fruit, vegetables, and meat. This study aimed to establish whether neophobia is associated with lower intake of these food types in naturalistic mealtime situations. Methods One hundred and nine parents of 4–5 year olds completed questionnaires which included a six-item version of the Child Food Neophobia Scale (CFNS. The children took part in a series of 3 test lunch meals at weekly intervals at school at which they were presented with: chicken, cheese, bread, cheese crackers, chocolate biscuits, grapes and tomatoes or carrot sticks. Food items served to each child were weighed before and after the meal to assess total intake of items in four categories: Fruit and vegetables, Protein foods, Starchy foods and Snack foods. Pearson Product Moment Correlations and independent t tests were performed to examine associations between scores on the CFNS and consumption during lunches. Results Neophobia was associated with lower consumption of fruit and vegetables, protein foods and total calories, but there was no association with intake of starch or snack foods. Conclusion These results support previous research that has suggested that neophobia impacts differentially on consumption of different food types. Specifically it appears that children who score highly on the CFNS eat less fruit, vegetables and protein foods than their less neophobic peers. Attempts to increase intake of fruit, vegetables and protein might usefully incorporate strategies known to reduce the neophobic response.

The aim of this study was to develop the Mastication Observation and Evaluation instrument for observing and assessing the chewing ability of children eating solid and lumpy foods. This study describes the process of item definition and item selection and reports the content validity, reproducibility and consistency of the instrument. In the developmental phase, 15 experienced speech therapists assessed item relevance and descriptions over three Delphi rounds. Potential items were selected based on the results from a literature review. At the initial Delphi round, 17 potential items were included. After three Delphi rounds, 14 items that regarded as providing distinctive value in assessment of mastication (consensus >75%) were included in the Mastication Observation and Evaluation instrument. To test item reproducibility and consistency, two experts and five students evaluated video recordings of 20 children (10 children with cerebral palsy aged 29-65 months and 10 healthy children aged 11-42 months) eating bread and a biscuit. Reproducibility was estimated by means of the intraclass correlation coefficient (ICC). With the exception of one item concerning chewing duration, all items showed good to excellent intra-observer agreement (ICC students: 0.73-1.0). With the exception of chewing duration and number of swallows, inter-observer agreement was fair to excellent for all items (ICC experts: 0.68-1.0 and ICC students: 0.42-1.0). Results indicate that this tool is a feasible instrument and could be used in clinical practice after further research is completed on the reliability of the tool. © 2013 Blackwell Publishing Ltd.

Little is known about the dietary patterns of Asian infants in the first year of life, nor of their associations with maternal socio-demographic factors. Based on the Growing Up in Singapore towards healthy Outcomes (GUSTO) mother-offspring cohort, cross-sectional dietary patterns were derived by factor analysis using 24-h recalls and food diaries of infants at 6-, 9- and 12-months of age. Dietary pattern trajectories were modeled by mapping similar dietary patterns across each age using multilevel mixed models. Associations with maternal socio-demographic variables, collected through questionnaires during pregnancy, were assessed using general linear models. In n = 486 infants, four dietary pattern trajectories were established from 6- to 12-months. Predominantly breastmilk: mainly breastmilk and less formula milk, rice porridge, vegetables, fruits and low-fat fish and meat, Easy-to-prepare foods: infant cereals, juices, cakes and biscuits and Noodles (in soup) and seafood: noodle and common accompaniments. In adjusted models, higher maternal education attainment was correlated with higher start scores on Predominantly breastmilk, but lowest education attainment increased its adherence over time. Older mothers had higher start scores on Easy-to-prepare foods, but younger mothers had increased adherence over time. Chinese mothers had higher start scores on Predominantly breastmilk but greater adherence to GUIDELINES over time, while Indian mothers had higher start scores on Easy-to-prepare foods but greater adherence to Predominantly breastmilk with time (p dietary patterns established during weaning are strongly influenced by maternal socio-demographic factors and remain stable over the first year of life.

Background: Long-term interventions based on the active involvement of students, carried out by properly prepared staff using didactic support material (brochures, games etc. including the participation/involvement of mothers or associates in community interventions; seem to be the most effective ones. This study evaluates the effectiveness of nutrition education interventions carried out by teachers with active didactic methodologies.

Methods: The research was carried out by administering a frequency of food intake questionnaire, before and after the intervention. To compare the answers given before and after the educational intervention the Wilcoxon-test was applied to dependent data discriminating the group with “sufficient implementation” of the project versus “insufficient implementation”.

Results: Our data demonstrates that a substantial percentage of children do not report an adequate nutritional intake, making education interventions not only opportune but necessary. In both groups there was an increase in the number of subjects having breakfast, particularly in terms of bread and biscuits intake. In the group with “sufficient implementation” there was an increase in the intake of all kinds of food with respect to the previous day’s intake and a decrease in the intake of meat, fish and legumes consumed during the previous week; in the group with “insufficient implementation” only fish intake increased significantly while vegetable intake decreased in a non-significant way. So this educational intervention appears to have been particularly effective in modifying breakfast habits and reducing snack.

Breast cancer patients receiving chemotherapy often experience symptoms such as nausea, vomiting and loss of appetite that potentially affect dietary habits. This study assessed the intake of energy, macronutrients and food groups before and during chemotherapy in breast cancer patients compared with women without cancer, and determined the association between symptoms and energy and macronutrient intake. This study included 117 newly diagnosed breast cancer patients scheduled for chemotherapy and 88 women without cancer. Habitual intake before chemotherapy was assessed with a food frequency questionnaire. Two 24-h dietary recalls were completed on random days for each participant during the whole chemotherapy treatment for patients and within 6 months after recruitment for women without cancer. Shortly, after the dietary recall, participants filled out questionnaires on symptoms. Before chemotherapy, habitual energy and macronutrient intake was similar for breast cancer patients and women without cancer. During chemotherapy, breast cancer patients reported a significantly lower total energy, fat, protein and alcohol intake than women without cancer, as shown by a lower intake of pastry and biscuits, cheese, legumes and meat products. A decline in subjective taste perception, appetite and hunger and experiencing a dry mouth, difficulty chewing, lack of energy and nausea were associated with a lower energy intake. Symptoms induced by chemotherapy are associated with lower dietary intake and manifested by a lower intake of specific food groups. To ensure an optimal dietary intake during chemotherapy, it is important to monitor nutritional status and symptom burden during chemotherapy in breast cancer patients.

The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

van der Kamp, Jan Willem; Poutanen, Kaisa; Seal, Chris J.; Richardson, David P.

2014-01-01

Most cereal products, like white bread, pasta, and biscuits, are based on flour after removal of bran and germ, the two parts of grain kernels containing most of the dietary fibre and other bioactive components. In the past decade, consumers have been rediscovering whole grain-based products and the number of wholegrain products has increased rapidly. In most countries in Europe and worldwide, however, no legally endorsed definition of wholegrain flour and products exists. Current definitions are often incomplete, lacking descriptions of the included grains and the permitted flour manufacturing processes. The consortium of the HEALTHGRAIN EU project (FP6-514008, 2005–2010) identified the need for developing a definition of whole grain with the following scope: 1) more comprehensive than current definitions in most EU countries; 2) one definition for Europe – when possible equal to definitions outside Europe; 3) reflecting current industrial practices for production of flours and consumer products; 4) useful in the context of nutritional guidelines and for labelling purposes. The definition was developed in a range of discussion meetings and consultations and was launched in 2010 at the end of the HEALTHGRAIN project. The grains included are specified: a wide range of cereal grains from the Poaceae family, and the pseudo-cereals amaranth, buckwheat, quinoa, and wild rice. The definition also describes manufacturing processes allowed for producing wholegrain flours. This paper compares the HEALTHGRAIN definition with previous definitions, provides more comprehensive explanations than in the definition itself regarding the inclusion of specific grains, and sets out the permitted flour manufacturing processes.

To report dietary sugars consumption and their different types and food sources, in European adolescents. Food consumption data of selected groups were obtained from 1630 adolescents (45.6% males, 12.5-17.5 years) from the HELENA study using two nonconsecutive 24-h recalls. Energy intake, total sugars and free sugars were assessed using the HELENA-DIAT software. Multiple regression analyses were performed adjusting for relevant confounders. Total sugars intake (137.5 g/day) represented 23.6% and free sugars (110.1 g/day), 19% of energy intake. Girls had significantly lower intakes of energy, carbohydrates, total sugars and free sugars. 94% of adolescents had a consumption of free sugars above 10% of total energy intake. The main food contributor to free sugars was 'carbonated, soft and isotonic drinks,' followed by 'non-chocolate confectionary' and 'sugar, honey, jam and syrup.' Older boys and girls had significantly higher intakes of free sugars from 'cakes, pies and biscuits.' Free sugars intake was negatively associated with low socioeconomic status for 'non-chocolate confectionary' and 'sugar, honey and jam' groups; with low maternal educational level for carbonated and 'soft drinks,' 'sugar, honey and jam,' 'cakes and pies' and 'breakfast cereals' groups; and with high paternal educational level for 'carbonated and soft drinks' and 'chocolates' group. The majority (94%) of studied adolescents consumed free sugars above 10% of daily energy intake. Our data indicate a broad variety in foods providing free sugars. Continued efforts are required at different levels to reduce the intake of free sugars, especially in families with a low educational level.

healthy dietary habits are considered to improve oral health and tooth quality. Caries treatment comprises tooth restoration with dental composites and sealants, almost all (> 90%) of which contain bisphenol A (BPA). Study hypotheses were: a) breakfast and oral hygiene habits are important factors in dental caries development; and b) dental caries treatment with epoxy-resins entails a risk of oral exposure to monomers migrating from the polymeric material. We evaluated caries in the teeth of a Spanish school population and determined the percentage treated with dental composites. to relate consumption of breakfast components and oral hygiene habits to dental caries and determine the presence of sealants/composites as potential sources of BPA exposure. subjects: 582 schoolchildren from Granada city (Southern Spain) aged 7 yrs; mean (SD) of 7.55 (0.64) yrs. caries was detected in 21.7% of their teeth. Mean breakfast quality index (BQI) score, based on nutritional questionnaires, was 5.18 (1.29). Breakfast with foods rich in simple sugars representing > 5% of total daily energy was consumed by 24% of the population and was significantly associated with caries frequency in binary logistic regression analysis. Biscuit consumption was reported by 35.8% and significantly associated with caries frequency. Breakfast intake of bakery products/ cereals and of dairy products showed a significant inverse association with caries frequency. No significant relationship was observed between caries and BQI score or oral hygiene factors. further research is required to elucidate the role of diet in caries and the associated risk of exposure to estrogenic xenobiotics such as BPA.

Full Text Available Although studies show that portion size affects energy intake, few have demonstrated a link between portion size and weight status, especially in free-living populations. The objective of the present study was to assess the relationship between food portion sizes and overweight in a representative population of adults of São Paulo, Brazil.Cross-sectional population-based study with 1005 adults from São Paulo, Brazil. Dietary data were obtained from two 24-hour recalls. Reported foods were classified into groups and energy contribution, prevalence of consumers and portion sizes were calculated. Individuals were classified according to BMI in with and without overweight. Logistic regression models were used to evaluate the association between food portion sizes and being overweight.The most consumed food groups were: beans, breads/rolls, coffee/tea, milk, rice, and sugar. Rice, red meat, breads/rolls, and white meat were the groups with the highest percentage of contribution to total energy intake. Butter/margarine, toasts/biscuits, sugar, and cakes were the groups with the highest energy density. After adjustment for confounding variables, overweight was associated with larger portions of pizza (OR = 1.052; p = 0.048, red meat (OR = 1.025; p = 0.043, rice (OR = 1.033; p<0.001, salted snacks (OR = 1.078; p = 0.022, and soft drinks (OR = 1.016; p = 0.007.Larger portions of few food groups with different energy densities were associated with being overweight, suggesting that overweight may be related to the consumption of larger portion sizes of a series of food groups, not a food group alone. Additionally, we highlight the importance of considering underreporting as a confounding factor in these associations.

Nutritional Aspects of Depression

Full Text Available Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics, which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials.

Incorporating meal replacements has been shown to produce a significantly greater weight loss than a conventional reduced calorie diet. Ready-to-eat conventional foods may also be effective in this role and provide additional benefit because of their palatability, acceptance and enjoyment and thus increase dietary compliance. This trial investigated the efficacy of a ready-to-eat food product (Vita-Weat biscuit) that is both high in carbohydrate and high in protein as part of a diet prescription for weight loss in an overweight and obese population group. A total of 76 participants were randomized to a 6-week weight loss intervention including the ready-to-eat food product (intervention group) or advice on the 'Australian Guide to Healthy Eating' (control group). Both groups lost approximately 2 kg weight which equated to a reduction in body mass index of 0.70 kg m(-2) . There was no significant difference in percentage weight loss from screening to 6 weeks between the two groups; mean difference for the intervention vs. -0.20% (95% confidence interval: -0.96, 1.36); P = 0.73. Both diets were nutritionally matched and well-accepted over the 6-week period. This study shows that the inclusion of a ready-to-eat food product can be included as part of a dietary programme to achieve a clinically significant weight loss over a short period. This may have benefit when incorporated into an individual's meal plan intermittently to assist weight control. It also provides support for current public health nutritional guidelines as the participants in this study following such advice were also successful in achieving a clinically meaningful weight loss. © 2016 World Obesity.

Inadequate nutrient intake as part of a complementary feeding diet is attributable to poor feeding practices and poor access to nutritious foods. Household socio-economic situation (SES) has an influence on food expenditure and access to locally available, nutrient-dense foods and fortified foods. This study aimed to develop and compare complementary feeding recommendations (CFR) for 12-23-month-old children in different SES and evaluate the contribution of fortified foods in meeting nutrient requirements. A cross-sectional survey was conducted in low and medium SES households (n 114/group) in urban Bandung district, West Java province, Indonesia. Food pattern, portion size and affordability were assessed, and CFR were developed for the low SES (LSES) and middle SES (MSES) using a linear programming (LP) approach; two models - with and without fortified foods - were run using LP, and the contribution of fortified foods in the final CFR was identified. Milk products, fortified biscuits and manufactured infant cereals were the most locally available and consumed fortified foods in the market. With the inclusion of fortified foods, problem nutrients were thiamin in LSES and folate and thiamin in MSES groups. Without fortified foods, more problem nutrients were identified in LSES, that is, Ca, Fe, Zn, niacin and thiamin. As MSES consumed more fortified foods, removing fortified foods was not possible, because most of the micronutrient-dense foods were removed from their food basket. There were comparable nutrient adequacy and problem nutrients between LSES and MSES when fortified foods were included. Exclusion of fortified foods in LSES was associated with more problem nutrients in the complementary feeding diet.

Wildfire, Fuels Reduction, and Herpetofaunas across Diverse Landscape Mosaics in Northwestern Forests

Science.gov (United States)

Bury, R. Bruce

2004-01-01

The herpetofauna (amphibians and reptiles) of northwestern forests (U.S.A.) is diverse, and many species are locally abundant. Most forest amphibians west of the Cascade Mountain crest are associated with cool, cascading streams or coarse woody material on the forest floor, which are characteristics of mature forests. Extensive loss and fragmentation of habitat resulted from logging across approximately 50% of old-growth forests in northern California and approximately 80% of stands in Oregon and Washington. There is a complex landscape mosaic and overlap of northern and southern biotic elements in the Klamath-Siskiyou Region along the Oregon and California border, creating a biodiversity hotspot. The region experiences many low-severity fires annually, punctuated by periodic major fires, including the Biscuit fire, the largest in North America in 2002. In the fire's northern portion, severe fire occurred on >50% of stands of young, managed trees but on only about 25a??33% of old-growth stands. This suggests that the legacy of timber harvest may produce fire-prone stands. Calls for prescribed fire and thinning to reduce fuel loads will remove large amounts of coarse woody material from forests, which reduces cover for amphibians and alters nutrient inputs to streams. Our preliminary evidence suggests no negative effects of wildfire on terrestrial amphibians, but stream amphibians decrease following wildfire. Most reptiles are adapted to open terrain, so fire usually improves their habitat. Today, the challenge is to maintain biodiversity in western forests in the face of intense political pressures designed to 'prevent' catastrophic fires. We need a dedicated research effort to understanding how fire affects biota and to proactively investigate outcomes of fuel-reduction management on wildlife in western forests.

In Egypt, the double burden of malnutrition and rising overweight and obesity in adults mirrors the transition to westernized diets and a growing reliance on energy-dense, low-nutrient foods. This study utilized the trials of improved practices (TIPs) methodology to gain an understanding of the cultural beliefs and perceptions related to feeding practices of infants and young children 0-23 months of age and used this information to work in tandem with 150 mothers to implement feasible solutions to feeding problems in Lower and Upper Egypt. The study triangulated in-depth interviews (IDIs) with mothers participating in TIPs, with IDIs with 40 health providers, 40 fathers and 40 grandmothers to gain an understanding of the influence and importance of the role of other caretakers and health providers in supporting these feeding practices. Study findings reveal high consumption of junk foods among toddlers, increasing in age and peaking at 12-23 months of age. Sponge cakes and sugary biscuits are not perceived as harmful and considered 'ideal' common complementary foods. Junk foods and beverages often compensate for trivial amounts of food given. Mothers are cautious about introducing nutritious foods to young children because of fears of illness and inability to digest food. Although challenges in feeding nutritious foods exist, mothers were able to substitute junk foods with locally available and affordable foods. Future programming should build upon cultural considerations learned in TIPs to address sustainable, meaningful changes in infant and young child feeding to reduce junk foods and increase dietary quality, quantity and frequency. © 2014 The Authors.

Full Text Available BACKGROUND AND AIM Junk food consumption is common among children that have much adverse effect on the growth of the children and health. This study is aimed to assess the correlation of frequency of junk food intake with the morphological changes of gastric antral biopsies in dyspeptic children. MATERIALS AND METHODS This cross-sectional observational study was carried out in Melmaruvathur Medical College Hospital, Melmaruvathur, during the year 2014-2015. The participants were dyspeptic children between 10-15 years of age. They were interviewed using various junk food frequency questionnaires and antral biopsy was taken for histopathological assessment. The morphological changes of gastric antral biopsies were recorded and their association with junk food was analysed. RESULTS Out of 37 children studied, the predominant age group affected were between 5-10 years (56.8% with female predominance (67%. Among the frequency, daily usage of junk food constitutes 57% of cases and the remaining 43% were taking intermittently. Biscuits, chocolates, packed chips were regularly used by daily user and bottled drinks, ice cream were used intermittently. Morphological assessment of gastritis showed significant association of junk food intake with increased intensity of mononuclear cell infiltration with a P value of 0.05, presence of Helicobacter pylori with a P value of 0.02 and presence of regenerative atypical changes with a P value of 0.006. CONCLUSION There is a significant association between the junk food intake and the severity of gastritis. The intensity of inflammatory changes, regenerative atypical glands and Helicobacter pylori presence and load were more among those having the habit of daily junk food intake than those taking intermittently.

This project-based learning combined the chemistry of separation process using steam distillation with engineering design process in an undergraduate chemistry course. Students built upon their knowledge of phase changes, immiscible mixture, and the relationship between vapor pressure and boiling point to complete a project of modifications steam distillation apparatus. The research method is a qualitative case study, which aims to describe how (1) the creative thinking skills of students emerged during six weeks of theproject, (2) students built steam distillation apparatus characteristics as the project product and (3) students response to the project-based learning model. The results showed that the students had successfully constructed a steam distillation apparatus using plastic kettle as steam generator and distillation flask. A Plastic tubewas used to drain water vapor from steam generator to distillation flask and to drain steam containing essential oil to the condenser. A biscuit tin filled with ice was used as a condenser. The time required until resulting distillate was fifteen minutes. The production of essential was conductive qualitatively by a very strong smell typical of essential oil and two phases of distillate. Throughout the project, students formulated the relevant and varied problem, formulated the goals, proposed the ideas of the apparatus and materials, draw apparatus design, constructed apparatus, tested apparatus, evaluated, and reported the project. Student response was generally positive. They were pleased, interested, more understanding the concepts and work apparatus principles, also implemented new ideas. These results indicate that project-based learning can develop students' creative thinking skills. Based on these results, it is necessary to conduct research and implemented project-based learning to other concepts.

Despite the reference to salt for food processing in the original definition of universal salt iodization (USI), national USI programs often do not explicitly address food industry salt. This may affect program impact and sustainability, given the increasing consumption of processed foods in developing countries. To review experience of the use of iodized salt in the food industry globally, and analyze the market context in Bangladesh and Pakistan to test whether this experience may be applicable to inform improved national USI programming in developing countries. A review of relevant international experience was undertaken. In Bangladesh and Pakistan, local rural market surveys were carried out. In Bangladesh, structured face-to-face interviews with bakers and indepth interviews with processed food wholesalers and retailers were conducted. In Pakistan, face-to-face structured interviews were conducted with food retailers and food labels were checked. Experience from industrialized countries reveals impact resulting from the use of iodized salt in the food industry. In Bangladesh and Pakistan, bread, biscuits, and snacks containing salt are increasingly available in rural areas. In Bangladesh, the majority of bakers surveyed claimed to use iodized salt. In Pakistan, 6 of 362 unique product labels listed iodized salt. Successful experience from developed countries needs to be adapted to the developing country context. The increasing availability of processed foods in rural Bangladesh and Pakistan provides an opportunity to increase iodine intake. However, the impact of this intervention remains to be quantified. To develop better national USI programs, further data are required on processed food consumption across population groups, iodine contents of food products, and the contribution of processed foods to iodine nutrition.

Eating slowly is associated with a lower body mass index. However, the underlying mechanism is poorly understood. Here, our objective was to determine whether eating a meal at a slow rate improves episodic memory for the meal and promotes satiety. Participants (N=40) consumed a 400ml portion of tomato soup at either a fast (1.97ml/s) or a slow (0.50ml/s) rate. Appetite ratings were elicited at baseline and at the end of the meal (satiation). Satiety was assessed using; i) an ad libitum biscuit 'taste test' (3h after the meal) and ii) appetite ratings (collected 2h after the meal and after the ad libitum snack). Finally, to evaluate episodic memory for the meal, participants self-served the volume of soup that they believed they had consumed earlier (portion size memory) and completed a rating of memory 'vividness'. Participants who consumed the soup slowly reported a greater increase in fullness, both at the end of the meal and during the inter-meal interval. However, we found little effect of eating rate on subsequent ad libitum snack intake. Importantly, after 3h, participants who ate the soup slowly remembered eating a larger portion. These findings show that eating slowly promotes self-reported satiation and satiety. For the first time, they also suggest that eating rate influences portion size memory. However, eating slowly did not affect ratings of memory vividness and we found little evidence for a relationship between episodic memory and satiety. Therefore, we are unable to conclude that episodic memory mediates effects of eating rate on satiety. Copyright © 2015. Published by Elsevier Inc.

The aim of the present study was to determine if the enzyme Aspergillus niger prolyl endoprotease (ANPEP), which degrades the immunogenic proline-rich residues in gluten peptides, can be used in the development of new wheat products, suitable for gluten-sensitive (GS) individuals. We have carried out a double-blind, randomised, cross-over trial with two groups of adults; subjects, self-reporting benefits of adopting a gluten-free or low-gluten diet (GS, n 16) and a control non-GS group (n 12). For the trial, volunteers consumed four wheat breads: normal bread, bread treated with 0·8 or 1 % ANPEP and low-protein bread made from biscuit flour. Compared with controls, GS subjects had a favourable cardiovascular lipid profile - lower LDL (4·0 (sem 0·3) v. 2·8 (sem 0·2) mmol/l; P=0·008) and LDL:HDL ratio (3·2 (sem 0·4) v. 1·8 (sem 0·2); P=0·005) and modified haematological profile. The majority of the GS subjects followed a low-gluten lifestyle, which helps to reduce the gastrointestinal (GI) symptoms severity. The low-gluten lifestyle does not have any effect on the quality of life, fatigue or mental state of this population. Consumption of normal wheat bread increased GI symptoms in GS subjects compared with their habitual diet. ANPEP lowered the immunogenic gluten in the treated bread by approximately 40 %. However, when compared with the control bread for inducing GI symptoms, no treatment effects were apparent. ANPEP can be applied in the production of bread with taste, texture and appearance comparable with standard bread.

Coriander (Coriandrum sativum L.), is an annual herb in the Apiaceae family which disperses in Mediterranean and Middle Eastern regions. The Coriander essential oil has been used in food products, perfumes, cosmetics and pharmaceutical industries for its flavor and odor. In Iran, fruits of Coriander used in pickle, curry powders, sausages, cakes, pastries, biscuits and buns. The aim of this study was to investigate microwave radiation effects on quality, quantity and antimicrobial activity of essential oil of Coriander fruits. The essential oils were obtained from the Coriander fruits by hydrodistillation (HD) and Microwave-assisted hydrodistillation (MAHD) then, the oils were analyzed by GC and GC-MS. Antimicrobial activities of essential oils were evaluated against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans by microdilution method. The results indicated that the HD and MAHD essential oils (EO) were dominated by monoterpenoids such as linalool, geranyl acetate and γ-terpinene. The major compound in both EO was linalool which its amount in HD and MAHD was 63 % and 66 %, respectively. The total amount of monoterpenes hydrocarbons in HD EO differ significantly with the amount in MAHD EO (12.56 % compare to 1.82 %). HD EO showed greater activity against Staphylococcus aureus and Candida albicans than MAHD EO. Moreover, their activities against Ecoli and P. aeruginosa were the same with Minimum Inhibitory Concentration (MIC) 0.781 and 6.25 μL mL(-1), respectively. By using MAHD method, it was superior in terms of saving energy and extraction time, although the oil yield and total composition decrease by using this method.

There is a scarcity of information about the dietary intake and food selection of combat sport people. Optimizing nutritional status, body weight, and body composition are key factors for their performance. The assessment of dietary intake, food habits, and body composition in elite combat sport people. 22 sportsmen were recruited from the Spanish National Teams of Tae kwon do, Judo, and Boxing. Food intake (FFQ), food habits and body composition (DXA and Bioimpedance) were analyzed. Weight and body composition of the individuals assessed were similar to that previously described, although almost half of them were moderately over their desired competition weight. A lower than the recommended intake of vegetables (77% of individuals), cereals, bread, rice, potatoes, and pasta (73%), while red meat and derivatives intake exceeded the recommendations. Their main preferences were pasta, meat, and cereals. Legumes, vegetables, and fish were their main dislikes. A statistically significant relationship between food preferences and intakes was only observed for legumes, yogurt, and nuts. The athletes reported that reducing the intake of biscuits and confectionery (68% of individuals), high-fat foods (36%), and/or bread (27%) would be a good dietetic strategy for losing weight. None of them reported that voluntary dehydration would be a good strategy for this purpose. food offer to which this sport people have access and their choices are adequate, although the intake of some food groups (vegetables, red meat and derivatives) does not follow the recommendations. Their body weight slightly exceeds their competition weight, what it is frequently found in these sports. Nevertheless, their knowledge about nutrition and dietetics applied to exercise are acceptable.

Effective population-specific, food-based complementary feeding recommendations (CFR) are required to combat micronutrient deficiencies. To facilitate their formulation, a modeling approach was recently developed. However, it has not yet been used in practice. This study therefore aimed to use this approach to develop CFR for 9- to 11-mo-old Indonesian infants and to identify nutrients that will likely remain low in their diets. The CFR were developed using a 4-phase approach based on linear and goal programming. Model parameters were defined using dietary data collected in a cross-sectional survey of 9- to 11-mo-old infants (n = 100) living in the Bogor District, West-Java, Indonesia and a market survey of 3 local markets. Results showed theoretical iron requirements could not be achieved using local food sources (highest level achievable, 63% of recommendations) and adequate levels of iron, niacin, zinc, and calcium were difficult to achieve. Fortified foods, meatballs, chicken liver, eggs, tempe-tofu, banana, and spinach were the best local food sources to improve dietary quality. The final CFR were: breast-feed on demand, provide 3 meals/d, of which 1 is a fortified infant cereal; > or = 5 servings/wk of tempe/tofu; > or = 3 servings/wk of animal-source foods, of which 2 servings/wk are chicken liver; vegetables, daily; snacks, 2 times/d, including > or = 2 servings/wk of banana; and > or = 4 servings/wk of fortified-biscuits. Results showed that the approach can be used to objectively formulate population-specific CFR and identify key problem nutrients to strengthen nutrition program planning and policy decisions. Before recommending these CFR, their long-term acceptability, affordability, and effectiveness should be assessed.

remarkable bryoliths of Celleporaria palmata, Turbicellepora coronopus, and reteporiform colonies of Reteporella sp. in the less densely-packed beds. The cirripede Creusia phryxa is very common. Pectinid assemblages are dominated by Hinnites crispus, H. ercolanianus, Manupecten pesfelis, Mimachlamys varia and Crassadoma multistriata. Oysters are represented by Neopycnodonte and large Hyotissa. The upper part of the lower interval records clumps of Neopycnodonte sp. This is the Pliocene locality in Spain recording the highest diversity of brachiopods: Novocrania anomala, Joania cordata, Megathiris detruncata, Megerlia truncata, Terebratulina retusa, Lacazella mediterranea, Aphelesia bipartita and Terebratula calabra. The latter two species are more abundant in the middle part of the section, Terebratula forming pavements. Most common echinoids are Stylocidaris? sp., Echinocyamus, and Arbacina, while fragments of spatangoids like Ova and Spatangus are less common. Crinoid cirrals and ophiourid vertebrae are scarce. The upper interval commences with sparse rhodolith debris while at the very top complete rhodoliths are the dominant bioclasts together with pectinids. Common taxa in the lower interval decrease in abundance or disappear. Pectinids are replaced by Pecten spp. and rare Gigantopecten latissimus; Aequipecten scabrellus is most abundant in the middle part and A. opercularis dominates at the very top. Fragments of Clypeaster start to occur and Ostrea is increasingly common. Preliminary results indicate a decrease of diversity concomitant with a shallowing upward trend.

Individuals with autism spectrum disorders (ASD) have impaired detoxification capacity. Investigating　the neurobiological bases of　impaired antioxidant capacity is thus a research priority in the pathophysiology of ASD.　We measured　the urinary levels of hexanoyl-lysine (HEL) which is a new oxidative stress　biomarker, total antioxidant power (TAP) and DNA methylation biomarker 8-hydroxy-2'-deoxyguanosine (8-OHdG), and the plasma levels of superoxide dismutase (SOD), which is a major antioxidant enzyme. We examined whether the urinary levels of these enzymes and biomarkers may be related to symptoms of social impairment in 20 individuals with ASD (meanage,11.1±5.2years) and 12 age- and gender-matched healthy controls (meanage,14.3±6.2years). Symptoms of social impairment were　assessed using the Social Responsiveness Scale (SRS). The dietary TAP of the fruit juice, chocolate, cookies, biscuits, jam and marmalade were significantly higher in the ASD group than in the control group, although the intake of nutrients was not significantly different between the groups. The urinary TAP levels were significantly lower in the ASD group than in the control group. There were no significantly differences in urinary HEL and 8-OHdG levels between the ASD and control groups. The SRS scores were significantly higher in the ASD group than in the control group. Stepwise regression analysis revealed that urinary TAP levels and plasma SOD levels can differences in the biomarkers and the SRS scores between the ASD group and the control group. The endogenous antioxidant capacity may be deficient without altered urinary HEL and 8-OHdG levels in individuals with ASD. The plasma SOD levels may be related to reduced endogenous antioxidant capacity. Copyright © 2016 ISDN. Published by Elsevier Ltd. All rights reserved.

Rats eat a cafeteria-style diet to excess but eat smaller amounts and less frequently when tested with chow.

Full Text Available BACKGROUND: Obesity is associated with excessive consumption of palatable, energy dense foods. The present study used an animal model to examine feeding patterns during exposure to and withdrawal from these foods. METHODS: Male Sprague Dawley rats were exposed to standard lab chow only (Chow rats or a range of cafeteria-style foods eaten by people (Caf rats. After 1, 4, 7 and 10 weeks of diet in their home cage, rats were subjected to 24-hour test sessions in a Comprehensive Lab Animal Monitoring System (CLAMS. In the first two test sessions, Chow rats were exposed to standard lab chow only while Caf rats were exposed to a biscuit and high-fat chow diet. In the final two test sessions, half the rats in each group were switched to the opposing diet. In each session we recorded numbers of bouts, energy consumed per bout, and intervals between bouts across the entire 24 hours. RESULTS: Relative to Chow rats, Caf rats initiated fewer bouts but consumed more energy per bout; however, their motivation to feed in the CLAMS declined over time, which was attributed to reduced variety of foods relative to their home cage diet. This decline in motivation was especially pronounced among Caf rats switched from the palatable CLAMS diet to standard lab chow only: the reduced energy intake in this group was due to a modest decline in bout frequency and a dramatic decline in bout size. CONCLUSIONS: Exposure to a cafeteria-diet, rich in variety, altered feeding patterns, reduced rats' motivation to consume palatable foods in the absence of variety, and further diminished motivation to feed when palatable foods were withdrawn and replaced with chow. Hence, variety is a key factor in driving excessive consumption of energy dense foods, and therefore, excessive weight gain.

Full Text Available The relationships between breadmaking quality, kernel properties (physical and chemical, and dough rheology were investigated using flours from six genotypes of Syrian wheat lines, comprising both commercially grown cultivars and advanced breeding lines. Genotypes were grown in 2008/2009 season in irrigated plots in the Eastern part of Syria. Grain samples were evaluated for vitreousness, test weight, 1000-kernel weight and then milled and tested for protein content, ash, and water content. Dough rheology of the samples was studied by the determination of the mixing time, stability, weakness, resistance and the extensibility of the dough. Loaf baking quality was evaluated by the measurement of the specific weight, resilience and firmness in addition to the sensory analysis. A comparative study between the six Syrian wheat genotypes and two English flour samples was conducted. Significant differences were observed among Syrian genotypes in vitreousness (69.3%–95.0%, 1000-kernel weight (35.2–46.9 g and the test weight (82.2–88.0 kg/hL. All samples exhibited high falling numbers (346 to 417 s for the Syrian samples and 285 and 305 s for the English flours. A significant positive correlation was exhibited between the protein content of the flour and its absorption of water (r = 0.84 **, as well as with the vitreousness of the kernel (r = 0.54 *. Protein content was also correlated with dough stability (r = 0.86 **, extensibility (r = 0.8 **, and negatively correlated with dough weakness (r = −0.69 **. Bread firmness and dough weakness were positively correlated (r = 0.66 **. Sensory analysis indicated Doumah-2 was the best appreciated whilst Doumah 40765 and 46055 were the least appreciated which may suggest their suitability for biscuit preparation rather than bread making.

Physico-chemical parameters observed during the purchase of grain (STN 461100-2 were not significantly different. Also milled flours from tested varieties have by processors required ash content, gluten, acceptable Zeleny index, α-amylase activity (falling number, but as the rheological properties of dough from these flours show, these parameters are unsuited enough (unsuitability of material for efficient processing of flour. Rheological evaluation showed that each variety is suitable for different processing direction. Therefore, if we deliberately separate lots of purchased grain, not only by basic physico-che­mi­cal properties listed in the current standards (CSN and STN, but also by their rheological properties, which are important and reliable indicator of the direction of the end-use processing of wheat flours, the flours will be more likely to succeed in specific cereal technology. For the production of bread was satisfactory rheological properties of dough from variety Arida. Verita variety is suitable for processing into wafers, and a variety Meritto for producing biscuits and crackers. Verita and Me­rit­to varieties so do not achieved the expected values of the rheological optimum for „classic“ bread processing (bakery products despite satisfactory gluten content and falling number to use this processing direction.

Full Text Available Wheat flour was fortified by 2.5 or 5.0 wt. per cent of linseed fibre, gained from seeds of golden flax varieties Amon and Raciol and brown one Recital (granulation 500 - 700 m, prepared from 2015 harvest. Technological quality of six flour composites was described analytically by Falling Number and Zeleny sedimentation test. Both screening methods shown a little impact on amylases activity and protein quality, respectively. Rheological tests included the farinograph, the extensigraph and the Rapid Visco Analyser (RVA proofs. Additions of brown and yellow flax fibre significantly increased farinograph water absorption and shortened dough stability, somewhat stronger by addition of brown linseed fibre. Extensigraph curves course depended on dough resting time, higher differences between wheat control and flour composites were observed after 60 min dough resting. Linseed fibre supported dough extensibility, and energy as area under curve significantly decreased about 7 - 18%, mainly due to increasing alternative material portion in dough. In general, fibre is characterised as hydrophilic material, and pasting profiles of flour composites confirmed this experience. During dough leavening, tested samples were differentiated according to maturograph dough resistance; optimal leavening time of wheat-linseed fibre dough was shorter than control. Regardless described modifications in dough machinability, specific volumes of bread buns were similar though whole sample set. A weak worsening of buns vaulting reflected a partial dilution of dough gluten skeleton. Cut-off biscuits were characterised by gradually lowering spread ratio, correspondingly to elevated dough elasticity. Laboratory prepared elbow-pasta have the same cooking time as the control (8.0 min, and data variation could not be attributed to linseed fibre or addition level. All three cereal products were found to have acceptable sensory profiles. PCA method verified partial lowering of

Determination of melamine in milk-based products and other food and beverage products by ion-pair liquid chromatography-tandem mass spectrometry

This paper describes a fast method for the sensitive and selective determination of melamine in a wide range of food matrices, including several milk-based products. The method involves an extraction with aqueous 1% trichloroacetic acid before the injection of the 10-fold diluted extract into the liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) system, using labelled melamine as the internal standard. As melamine is present in aqueous media in the cationic form, the chromatographic separation in reversed-phase LC requires the use of anionic ion-pair reagents, such as tridecafluoroheptanoic acid (THFA). This allows a satisfactory chromatographic retention and peak shape in all the types of food samples investigated. The method has been validated in six food matrices (biscuit, dry pasta and four milk-based products) by means of recovery experiments in samples spiked at 1 and 5 mg kg{sup -1}. Average recoveries (n = 5) ranged from 77% to 100%, with excellent precision (RSDs lower than 5%) and limits of detection between 0.01 and 0.1 mg kg{sup -1}. In addition, accuracy and robustness of the method was proven in different soya-based matrices by means of quality control (QC) sample analysis. QC recoveries, at 1 and 2.5 mg kg{sup -1}, were satisfactory, ranging from 79% to 110%. The method developed in this work has been applied to the determination of melamine in different types of food samples. All detections were confirmed by acquiring two MS/MS transitions (127 > 85 for quantification; 127 > 68 for confirmation) and comparing their ion intensity ratio with that of reference standards. Accuracy of the method was also assessed by applying it to a milk-based product and a baking mix material as part of an EU proficiency test, in which highly satisfactory results were obtained.

The aim of this study was to determine the measurement reproducibility for a procedure evaluating the mastication process and to estimate the smallest detectable differences of 3D kinematic and surface electromyography (sEMG) variables. Kinematics of mandible movements and sEMG activity of the masticatory muscles were obtained over two sessions with four conditions: two food textures (biscuit and bread) of two sizes (small and large). Twelve healthy adults (mean age 29.1 years) completed the study. The second to the fifth chewing cycle of 5 bites were used for analyses. The reproducibility per outcome variable was calculated with an intraclass correlation coefficient (ICC) and a Bland-Altman analysis was applied to determine the standard error of measurement relative error of measurement and smallest detectable differences of all variables. ICCs ranged from 0.71 to 0.98 for all outcome variables. The outcome variables consisted of four bite and fourteen chewing cycle variables. The relative standard error of measurement of the bite variables was up to 17.3% for 'time-to-swallow', 'time-to-transport' and 'number of chewing cycles', but ranged from 31.5% to 57.0% for 'change of chewing side'. The relative standard error of measurement ranged from 4.1% to 24.7% for chewing cycle variables and was smaller for kinematic variables than sEMG variables. In general, measurements obtained with 3D kinematics and sEMG are reproducible techniques to assess the mastication process. The duration of the chewing cycle and frequency of chewing were the best reproducible measurements. Change of chewing side could not be reproduced. The published measurement error and smallest detectable differences will aid the interpretation of the results of future clinical studies using the same study variables.

The exact mechanisms which contribute to longevity have not been figured out yet. Our aim was to find out a common way for prompting longevity by bringing together the well-known applications such as food restriction, exercise, and probiotic supplementing in an experimental obesity model. Experimental obesity was promoted in a total of 32 young (2 months old) and 32 aged (16 months old) male Wistar albino rats through 8-week cafeteria diet (salami, chocolate, chips, and biscuits). Old and young animals were divided into groups each consisting of eight animals and also divided into four subgroups as obese control, obese food restriction, obese probiotic-fed and obese exercise groups. Probiotic group diet contained 0.05 %w/total diet inactive and lyophilized Lactobacillus casei str. Shirota. The exercise group was subjected to treadmill running 1 h/day, at 21 m/min and at an uphill incline of 15 % for 5 days a week. Food restriction group was formed by giving 40 % less food than the others. The control group was fed regular pellet feed ad libitum. This program was continued for 16 weeks. Blood samples from all the groups were analyzed for fasting glucose, insulin, IGF-1, insulin-like growth factor binding protein 3 (IGFBP-3), interleukin (IL)-6, IL-12, malondialdehyde (MDA), fT3, TT3, fT4, TT4, and liver tissue MDA levels were measured. All applications showed anti-inflammatory effects through the observed changes in the levels of IGFBP-3, IL-6, and IL-12 in the young and old obese rats. While the interventions normally contribute to longevity by recruiting different action mechanisms, anti-inflammatory effect is the only mode of action for all the applications in the obesity model.

Phosphorus-based food additives may pose a significant risk in chronic kidney disease given the link between hyperphosphatemia and cardiovascular disease. The objective of the study was to determine the prevalence of phosphorus-based food additives in best-selling processed grocery products and to establish how they were reported on food labels. A data set of 3000 best-selling grocery items in Australia across 15 food and beverage categories was obtained for the 12 months ending December 2013 produced by the Nielsen Company's Homescan database. The nutrition labels of the products were reviewed in store for phosphorus additives. The type of additive, total number of additives, and method of reporting (written out in words or as an E number) were recorded. Presence of phosphorus-based food additives, number of phosphorus-based food additives per product, and the reporting method of additives on product ingredient lists. Phosphorus-based additives were identified in 44% of food and beverages reviewed. Additives were particularly common in the categories of small goods (96%), bakery goods (93%), frozen meals (75%), prepared foods (70%), and biscuits (65%). A total of 19 different phosphorus additives were identified across the reviewed products. From the items containing phosphorus additives, there was a median (minimum-maximum) of 2 (1-7) additives per product. Additives by E number (81%) was the most common method of reporting. Phosphorus-based food additives are common in the Australian food supply. This suggests that prioritizing phosphorus additive education may be an important strategy in the dietary management of hyperphosphatemia. Further research to establish a database of food items containing phosphorus-based additives is warranted. Copyright © 2015 National Kidney Foundation, Inc. Published by Elsevier Inc.

To examine associations between dietary patterns identified by factor analysis, and successful ageing. Prospective cohort study with diet measured in 1990-4, and successful ageing in 2003-7. Ordered logistic regression with outcome determined as dead/usual ageing/successful ageing was used to examine associations with quintile groups of dietary factor scores. Men and women (n=6308), without history of major illness at baseline, and aged >70 years at follow-up, or who had died before follow-up but would have been aged >70 at the commencement of follow-up, from the Melbourne Collaborative Cohort Study. Frequencies of intake of 121 foods at baseline were collected in a food frequency questionnaire. Anthropometry and other health and lifestyle data were collected. At follow-up, questionnaire data relating to mental health, physical function and medical history were used to define successful ageing. Four dietary factors were identified, characterized by higher loadings for (1) vegetables; (2) fruit, (3) feta, legumes, salad, olive oil, and inverse loadings for tea, margarine, cake, sweet biscuits and puddings; (4) meat, white bread, savoury pastry dishes and fried foods. In models excluding body size, the second factor 'Fruit' was positively associated with successful ageing (OR in top 20% vs lowest 20% of score 1.31, 95%CI (1.05-1.63), p trend across quintile groups 0.001); while the fourth factor 'Meat/fatty foods' was inversely associated (OR in top 20% vs lowest 20% of score 0.69, 95%CI (0.55-0.86), p trend across quintile groups 0.001). Factors 1 and 3 did not show significant associations with successful ageing. The association for 'Fruit' was little altered after adjustment for body size, while for 'Meat/fatty foods' the association was somewhat attenuated. A dietary pattern including plenty of fruit while limiting meat and fried foods may improve the likelihood of ageing successfully.

Full Text Available The principal aims of this study are to describe breakfast consumption patterns of south-eastern Spanish adolescents, examine the relationship between breakfast consumption and feelings of well-being and fitness and compare breakfast behaviour between men and women to identify if there is a gender gap. Design: A cross-sectional research with cluster sampling in two primary schools and seven secondary schools. The instrument used was a modified version of the Kidscreen-27 questionnaire. Sample: 2,125 students aged between 10 and 19 years old from different nationalities, mainly Romanian, Moroccan and Spanish. Results: The study identifies some youngsters who skip breakfast and no have no food intake over the course of the morning. About 35% of the teenagers skip daily breakfast before they leave for school, and a worrying 1,8% do not eat any food during the whole morning. Questionnaire outcomes also expresses that the amount of biscuits ingested increased as the number of times that adolescents have breakfast at home decreases. There are significant gender differences, women it less foods than men. Differences are especially significant in case of milk, bread or cereals and butter or oil. Finally, chisquare contrast analysis show students that have breakfast before leaving to school perceive better feelings about how well and fit they are than those student who do not have breakfast daily. Conclusions. Findings supports the need for further enhance health education programs focused on breakfast habits, especially with women.

A novel label-free voltammetric immunosensor for sensitive detection of β-lactoglobulin using graphene modified screen printed electrodes has been developed. The derivatization of the graphene electrode surface was achieved by electrochemical reduction of in situ generated 4-nitrophenyl diazonium cations in aqueous acidic solution, followed by electrochemical reduction of the terminal nitro groups to amines. The electrochemical modification protocol was optimized in order to generate monolayer of nitrophenyl groups on the graphene surface without complete passivation of the electrode. Unlike the reported method for graphene functionalization, we demonstrated here the ability of the electrografting of aryl diazonium salt to attach an organic film to the graphene surface in a controlled manner by choosing the suitable grafting protocol. Next, the amine groups on the graphene surface were activated using glutaraldehyde and used for the covalent immobilization of β-lactoglobulin antibodies. Cyclic and differential pulse voltammetry carried out in an aqueous solution containing [Fe(CN)(6)](3-/4-) redox pair have been used for the immunosensor characterization. The results demonstrated that the DPV reduction peak current of [Fe(CN)(6)](3-/4-) decreased linearly with increasing the concentration of β-lactoglobulin due to the formation of antibody-antigen complex on the modified electrode surface. The immunosensor obtained using this novel approach enabled a detection limit of 0.85 pg mL(-1) and a dynamic range from 1 pg mL(-1) to 100 ng mL(-1) of β-lactoglobulin in PBS buffer. In addition, the immunosensor evaluated in different samples including cake, cheese snacks, a sweet biscuit, showing excellent correlation with the results obtained from commercially enzyme-linked immunosorbent assay (ELISA) method.

High energy diets have been shown to impair cognition however, the rapidity of these effects, and the dietary component/s responsible are currently unclear. We conducted two experiments in rats to examine the effects of short-term exposure to a diet rich in sugar and fat or rich in sugar on object (perirhinal-dependent) and place (hippocampal-dependent) recognition memory, and the role of inflammatory mediators in these responses. In Experiment 1, rats fed a cafeteria style diet containing chow supplemented with lard, cakes, biscuits, and a 10% sucrose solution performed worse on the place, but not the object recognition task, than chow fed control rats when tested after 5, 11, and 20 days. In Experiment 2, rats fed the cafeteria style diet either with or without sucrose and rats fed chow supplemented with sucrose also performed worse on the place, but not the object recognition task when tested after 5, 11, and 20 days. Rats fed the cafeteria diets consumed five times more energy than control rats and exhibited increased plasma leptin, insulin and triglyceride concentrations; these were not affected in the sucrose only rats. Rats exposed to sucrose exhibited both increased hippocampal inflammation (TNF-α and IL-1β mRNA) and oxidative stress, as indicated by an upregulation of NRF1 mRNA compared to control rats. In contrast, these markers were not significantly elevated in rats that received the cafeteria diet without added sucrose. Hippocampal BDNF and neuritin mRNA were similar across all groups. These results show that relatively short exposures to diets rich in both fat and sugar or rich in sugar, impair hippocampal-dependent place recognition memory prior to the emergence of weight differences, and suggest a role for oxidative stress and neuroinflammation in this impairment.

Stevia rebaudiana Bertoni is a plant which produces a variety of high-potency, low-calorie sweetener in its leaf tissue (Jarma et al ., 2006). The leaves of this plant contain sweet diterpene glucosides; rebaudioside A, rebaudioside C, stevioside and dulcoside. Stevioside is about 110 to 270 times sweeter than sucrose, while rebaudioside A is 150 to 320 times sweeter than sucrose (Yao et al., 1999). The leaves also produce biologically active substances, e.g. flavonoids, coumarins, cinnamic acids and essential oil (Dzyuba, 1998). (Lobov and Yurtaeva, 2002) showed that diterpenoid glycosides from leaves of S. rebaudiana were the most promising non-sugar sweeteners of plant origin for food and pharmaceutical industries to overcome the problem of human diseases related to disorders of carbon metabolism. The sweetener from leaves has a good taste and is suitable for use in food products as chocolates, marmalades, biscuits, ice-cream, sweets, juices, beverages and candy. The dried leaves could be mixed within the tea packages to reduce the consumption of sugar. The stevioside does not induce tooth decay could safely by used by diabetic patients and could be used in the low caloric diets to reduce human body weight without side effects for these reasons many countries are now using this plant to produce a larger portion of their sugar consumption (El-Zifzafi, 2003). Stevia, Stevia rebaudiana Bertoni is a small herbaceous plant (2 n = 22). It is a member of compositae family (Yao et al., 1999). Estimates of total number of species in this genus ranges from 150 to 300 . Stevia rebaudiana is one of the species of the genus stevia, which includes S.eupatoria, S.purpurea and S .serrata (Lisitsin and kovalev, 2000).

This study aims to examine repeatability of reduced rank regression (RRR) methods in calculating dietary patterns (DP) and cross-sectional associations with overweight (OW)/obesity across European and Australian samples of adolescents. Data from two cross-sectional surveys in Europe (2006/2007 Healthy Lifestyle in Europe by Nutrition in Adolescence study, including 1954 adolescents, 12-17 years) and Australia (2007 National Children's Nutrition and Physical Activity Survey, including 1498 adolescents, 12-16 years) were used. Dietary intake was measured using two non-consecutive, 24-h recalls. RRR was used to identify DP using dietary energy density, fibre density and percentage of energy intake from fat as the intermediate variables. Associations between DP scores and body mass/fat were examined using multivariable linear and logistic regression as appropriate, stratified by sex. The first DP extracted (labelled 'energy dense, high fat, low fibre') explained 47 and 31 % of the response variation in Australian and European adolescents, respectively. It was similar for European and Australian adolescents and characterised by higher consumption of biscuits/cakes, chocolate/confectionery, crisps/savoury snacks, sugar-sweetened beverages, and lower consumption of yogurt, high-fibre bread, vegetables and fresh fruit. DP scores were inversely associated with BMI z-scores in Australian adolescent boys and borderline inverse in European adolescent boys (so as with %BF). Similarly, a lower likelihood for OW in boys was observed with higher DP scores in both surveys. No such relationships were observed in adolescent girls. In conclusion, the DP identified in this cross-country study was comparable for European and Australian adolescents, demonstrating robustness of the RRR method in calculating DP among populations. However, longitudinal designs are more relevant when studying diet-obesity associations, to prevent reverse causality.

The aim of the present study was to examine whether a replacement diet with products made with organic ancient khorasan wheat could provide additive protective effects in reducing glucose, insulin, lipid and inflammatory risk factors, and in restoring blood redox balance in type 2 diabetes mellitus (T2DM) patients compared to diet with product made with modern organic wheat. We conducted a randomized, double-blinded crossover trial with two intervention phases on 21 T2DM patients (14 females, 7 males). The participants were assigned to consume products (bread, pasta, crackers and biscuits) made using semi-whole flour from organic wheat that was either from ancient khorasan wheat or modern control wheat for 8 weeks in a random order. An 8-week washout period was implemented between the interventions. Laboratory analyses were performed both at the beginning and at the end of each intervention phase. The metabolic risk profile improved only after the khorasan intervention period, as measured by a reduction in total and LDL cholesterol (mean reduction: -3.7 and -3.4 %, respectively), insulin (-16.3 %) and blood glucose (-9.1 %). Similarly, there was a significant reduction in circulating levels of reactive oxygen species (ROS), vascular endothelial growth factor (VEGF) and interleukin-1ra, and a significant increase of total antioxidant capacity (+6.3 %). No significant differences from baseline were noted after the modern control wheat intervention phase. The change (from pre- to post-intervention) between the two intervention arms was significantly different (p diet with ancient khorasan wheat consumption provided additive protection in reducing total and LDL cholesterol, insulin, blood glucose, ROS production, and some inflammatory risk factors, which are all key factors warranting of control in secondary prevention of T2DM compared to a diet with products made with modern wheat.

Determination of melamine in milk-based products and other food and beverage products by ion-pair liquid chromatography-tandem mass spectrometry

This paper describes a fast method for the sensitive and selective determination of melamine in a wide range of food matrices, including several milk-based products. The method involves an extraction with aqueous 1% trichloroacetic acid before the injection of the 10-fold diluted extract into the liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) system, using labelled melamine as the internal standard. As melamine is present in aqueous media in the cationic form, the chromatographic separation in reversed-phase LC requires the use of anionic ion-pair reagents, such as tridecafluoroheptanoic acid (THFA). This allows a satisfactory chromatographic retention and peak shape in all the types of food samples investigated. The method has been validated in six food matrices (biscuit, dry pasta and four milk-based products) by means of recovery experiments in samples spiked at 1 and 5 mg kg -1 . Average recoveries (n = 5) ranged from 77% to 100%, with excellent precision (RSDs lower than 5%) and limits of detection between 0.01 and 0.1 mg kg -1 . In addition, accuracy and robustness of the method was proven in different soya-based matrices by means of quality control (QC) sample analysis. QC recoveries, at 1 and 2.5 mg kg -1 , were satisfactory, ranging from 79% to 110%. The method developed in this work has been applied to the determination of melamine in different types of food samples. All detections were confirmed by acquiring two MS/MS transitions (127 > 85 for quantification; 127 > 68 for confirmation) and comparing their ion intensity ratio with that of reference standards. Accuracy of the method was also assessed by applying it to a milk-based product and a baking mix material as part of an EU proficiency test, in which highly satisfactory results were obtained.

In some specimens are observed in the mouth secretions transparent and light yellow in the anal region (under study), response evidenced in adult insects control of this species (author)

Nutritional aspects of depression.

2015-01-01

Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota) acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics), which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials. © 2015 The Author(s) Published by S

Chemical analysis of polar pesticides has been qualitatively interest in forensic scientific research by toxicological qualities to the attainment of crimes against human life, pets and plants; associating people and objects in the scene and the possible ways in which the events occurred. The Unidad de Toxicos y Varios of the Seccion de Quimica Analitica of the Departamento de Ciencias Forenses has analyzed polar pesticides and other families to concentration levels, is compared to the environmental analysis and quality control of food. The compounds are used in Costa Rica in recent years as acute chemical weapon to commit crimes against human and animal life. The toxic and lethal amounts of polar pesticides in mammals orally have been milligram level. The Seccion de Quimica Analitica has developed a qualitative methodology to analyze polar pesticides as minor components. The need for reliable analytical quality results has made it necessary to approach a review of the methodology of routine. The review has been solved by selecting two matrices characteristics in such cases: a solid food commercially known as maria biscuits and a carbonated cola. Analytes have been selected based on: greater toxicity, broad spectrum of analytes polarity, the octanol-water partition constant, the water solubility among others. The extraction of analytes in matrices has been selected by solid-phase extraction. The instrumental technique used is gas chromatography with mass selective detector. A method of acquisition optimized in its injection is used. The analysis of instrumental signals were obtained in scanning mode all ions formed, known as Scan and by monitoring mode of ions selected ions (MIS), analysis of the data is acquired in Scan mode because concentration levels of work. The methodology for the qualitative determination of pesticide meets the criteria established for the chemical identification of analytes carbofuran, phorate, terbufos, methyl parathion, chlorpyrifos and

The prevalence of obesity has increased simultaneously with the increase in the consumption of large food portion sizes (FPS). Studies investigating this association among adolescents are limited; fewer have addressed energy-dense foods as a potential risk factor. In the present study, the association between the portion size of the most energy-dense foods and BMI was investigated. A representative sample of 636 British adolescents (11-18 years) was used from the 2008-2011 UK National Diet and Nutrition Survey. FPS were estimated for the most energy-dense foods (those containing above 10·5 kJ/g (2·5 kcal/g)). Regression models with BMI as the outcome variable were adjusted for age, sex and misreporting energy intake (EI). A positive association was observed between total EI and BMI. For each 418 kJ (100 kcal) increase in EI, BMI increased by 0·19 kg/m2 (95 % CI 0·10, 0·28; Pportion sizes of a limited number of high-energy-dense foods (high-fibre breakfast cereals, cream and high-energy soft drinks (carbonated)) were found to be positively associated with a higher BMI among all adolescents after adjusting for misreporting. When eliminating the effect of under-reporting, larger portion sizes of a number of high-energy-dense foods (biscuits, cheese, cream and cakes) were found to be positively associated with BMI among normal reporters. The portion sizes of only high-fibre breakfast cereals and high-energy soft drinks (carbonated) were found to be positively associated with BMI among under-reporters. These findings emphasise the importance of considering under-reporting when analysing adolescents' dietary intake data. Also, there is a need to address adolescents' awareness of portion sizes of energy-dense foods to improve their food choice and future health outcomes.

Full Text Available Anaemia in school aged girls is an important but neglected issue. Since iron supplementation programmes have had little reported success in reducing anaemia, interest is turning to food based approaches that have higher potential for achieving far reaching benefits. The purpose of the study was to observe sustainability of the effect of iron and food supplementation on haemoglobin (Hb, intelligence quotient (IQ and growth of the subjects. At baseline, estimation of haemoglobin (Hb, red cell indices, serum iron, total iron binding capacity, serum transferrin saturation and serum ferritin was done. IQ, weight and height were measured using standard procedures. Anaemic subjectswere divided into three groups, viz., (i twice weekly supplementation of iron folic acid syrup (53 mg iron/week; (ii daily supplementation of 4 niger seed and defatted soyaflour biscuits plus 2 lemons (45 mg iron/week and (iii control. Non anaemic group(NAC was not intervened. Endline data was collected after 120 days. Follow up for Hb, IQ, weight and height was done 4 months after cessation of supplementation. The prevalence of anaemia was 77% in the study population; 46% subjects had mild anaemia and 32% had moderate anaemia. Iron status was lower in anaemic subjects (p<0.001.Iron supplementation was more effective in raising Hb and building iron stores than iron rich food supplementation. Iron supplementation improved IQ but did not bring about catch up of anaemics to non anaemics. Iron rich food supplementation was better than medicinal iron in promoting growth in anaemic girls. The impact of iron rich food supplementation on Hb, IQ and growth sustained for 4 months while that of medicinal iron did not. Effects of food supplementation are sustainable for 4 months, therefore, this strategy holds more potential to control anaemia, in school aged girls.

We propose a new recognition task in the area of computational paralinguistics: automatic recognition of eating conditions in speech, i. e., whether people are eating while speaking, and what they are eating. To this end, we introduce the audio-visual iHEARu-EAT database featuring 1.6 k utterances of 30 subjects (mean age: 26.1 years, standard deviation: 2.66 years, gender balanced, German speakers), six types of food (Apple, Nectarine, Banana, Haribo Smurfs, Biscuit, and Crisps), and read as well as spontaneous speech, which is made publicly available for research purposes. We start with demonstrating that for automatic speech recognition (ASR), it pays off to know whether speakers are eating or not. We also propose automatic classification both by brute-forcing of low-level acoustic features as well as higher-level features related to intelligibility, obtained from an Automatic Speech Recogniser. Prediction of the eating condition was performed with a Support Vector Machine (SVM) classifier employed in a leave-one-speaker-out evaluation framework. Results show that the binary prediction of eating condition (i. e., eating or not eating) can be easily solved independently of the speaking condition; the obtained average recalls are all above 90%. Low-level acoustic features provide the best performance on spontaneous speech, which reaches up to 62.3% average recall for multi-way classification of the eating condition, i. e., discriminating the six types of food, as well as not eating. The early fusion of features related to intelligibility with the brute-forced acoustic feature set improves the performance on read speech, reaching a 66.4% average recall for the multi-way classification task. Analysing features and classifier errors leads to a suitable ordinal scale for eating conditions, on which automatic regression can be performed with up to 56.2% determination coefficient.

Food is increasingly a packaged commodity, both in the community and in institutionalised settings such as hospitals, where many older people are malnourished. Previous research with patients aged over 65 years in NSW public hospitals identified difficulties opening milk, water, juices, cereal and tetra packs. The aim of this paper was to assess the ability of well older people living in the community to open food and beverage items routinely used in NSW hospitals in order to gain further insights into the older person/pack interaction and the role of hand and finger strength in pack opening. A sample of 40 older people in good health aged over 65 years from 3 community settings participated in the study. The attempts at pack opening were observed, the time taken to open the pack was measured and the correlation between grip and pinch strengths with opening times was determined. Tetra packs, water bottles, cereal, fruit cups, desserts, biscuits and cheese portions appeared to be the most difficult food products to open. Ten percent of the sample could not open the water bottles and 39% could not open cheese portions. The results were consistent with the previous research involving hospitalised older adults, adding emphasis to the conclusion that food and beverage packaging can be a potential barrier to adequate nutrition when particular types of packaged products are used in hospitals or the community. The ageing population is rapidly becoming a larger and more important group to consider in the provision of goods and services. Designers, manufacturers and providers of food and beverage products need to consider the needs and abilities of these older consumers to ensure good 'openability' and promote adequate nutritional intakes.

Full Text Available Fats and oils are very important raw materials and functional ingredients for several food products such as confectionery, bakery, ice creams, emulsions, and sauces, shortenings, margarines, and other specially tailored products. Formulated products are made with just about every part of chemistry, but they are not simple chemicals. In general, they consist of several, and often many, components. Each of these components has a purpose. Most formulated products have a micro- or nano-structure that is important for their function, but obtaining this structure is often the big challenge. Due to a rise in overweight or obesity, health concerns have increased. This fact has led to the need to the develop products with low fat content, which have become a market trend. In addition, the development of new products using fat substitutes can be a good option for companies that are always trying to reduce costs or substitute trans fat or saturated fat. However, the successful development of these products is still a challenge because fat plays multiple roles in determining the desirable physicochemical and sensory attributes, and because the consumers who want or need to replace these ingredients, seek products with similar characteristics to those of the original product. Important attributes such as smooth, creamy and rich texture; milky and creamy appearance; desirable flavor; and satiating effects are influenced by the droplets of fat, and these characteristics are paramount to the consumer and consequently crucial to the success of the product in the market. Therefore, it is important to identify commercially viable strategies that are capable of removing or reducing fat content of food products without altering their sensory and nutritional characteristics. This paper intended to provide an overview about the role of fat in different food systems such as chocolate, ice cream, bakery products like biscuits, breads, and cakes considering the major

Clear as Mud: Changes in Paleoshelf Environments and Deposition Rates at Medford, New Jersey during the Paleocene-Eocene Thermal Maximum

The Paleocene-Eocene boundary marks a time of swift global climatic change. Constraining the timeframe of this event is a first order question necessary for ascertaining the origin of the event and the potential for its use as an analog for modern climate change. The New Jersey shelf sediments of the Marlboro Formation records this time period with exceptionally thick (5-15m) records of the period of global low carbon isotopic values ("the core") which requires minimum sedimentation rates of 10's cm/kyr. Rhythmic layers have been previously reported from Wilson Lake & Millville, NJ (IODP Leg 174AX). These structures coined "laminae couplets" consist of semi-periodic 1-2mm thick raised laminations separated by matrix of varying width (averaging 1.8cm). These have been dismissed as artifacts of drilling "biscuits". We report here on a series of shallow auger cores drilled on a transect at Medford, NJ, without using drilling fluid. These cores also show a similar set of structures on the 2cm scale verifying that they are primary depositional features. The mm width laminae in the auger core show remarkable swelling within minutes of splitting. XRD, XRF, bulk carbonate geochemistry, and grain size analysis have been determined at regular depth intervals throughout the core. We have analyzed differences in these parameters between the laminae and interbedded matrix material, as well as across the transect as a whole. In general, the Marlboro formation at this updip location consists of micaceous, lignitic, very clayey silt (mean size 6 micrometers) with occasional organic debris indicating proximal deposition from a fluvial system. Paleodepth of 40m and normal marine salinities are estimated using a paleoslope model and the presence of common though not abundant planktonic foraminifera. We discuss a model of deposition for the Marlboro Formation as fluid mud (nearbed suspension flows) associated with the "Appalachian Amazon" alluding toward the finer grained inter

Dietary trans fatty acids (TFAs) increase the risk of heart disease. In 2007, Canada set voluntary TFA limits for industrial TFAs added to food and encouraged substitution of TFAs with unsaturated fats during reformulation. No longitudinal follow-up assessment of TFA amounts in foods has occurred in Canada since termination of a government-led Trans Fat Monitoring Program (TFMP). The objective was to conduct an updated assessment and longitudinally evaluate TFA amounts in the food supply and to determine whether saturated fats have replaced TFAs in reformulation. This was a cross-sectional study that used 3 databases: TFMP (Health Canada, 2005-2009; n = 921), the University of Toronto Food Label Information Program (2010-2011; n = 5544), and the Restaurant Database (2010; n = 4272). Outcomes were TFAs as a percentage of fat, proportion of foods meeting TFA limits, and saturated fat amounts in foods with high or low TFAs. The proportion of foods meeting TFA limits improved from 75% in 2005-2009 to 97% in 2010-2011, particularly in the following packaged foods: croissants (25% to 100%), pies (36% to 98%), cakes (43% to 90%), and garlic spreads (33% to 100%). Most restaurant categories assessed by the TFMP had 100% of foods meeting TFA limits. Some categories had a large proportion that exceeded TFA limits: dairy-free cheeses (100%), frosting (72.0%), lard and shortening (66.7%), coffee whiteners (66.7%), and restaurant-prepared biscuits and scones (47.4%). Saturated fat amounts were significantly higher (P foods with the lowest TFAs, such as cookies, brownies and squares, cakes with pudding/mousse, dessert toppings, and lard and shortening. There has been an impressive improvement in TFA amounts in the Canadian food supply since the termination of the TFMP. However, action by the food industry is required to reduce TFAs in foods that exceed the recommended TFA limits and to minimize the use of saturated fats in replacing TFAs during reformulation. © 2014 American

Poor cooking skills may be a barrier to healthy eating and a contributor to overweight and obesity. Little population-representative data on adult cooking skills has been published. We explored prevalence and socio-demographic correlates of cooking skills among adult respondents to wave 1 of the UK National Diet and Nutrition Survey (2008-9). Socio-demographic variables of interest were sex, age group, occupational socio-economic group and whether or not respondents had the main responsibility for food in their households. Cooking skills were assessed as self-reported confidence in using eight cooking techniques, confidence in cooking ten foods, and ability to prepare four types of dish (convenience foods, a complete meal from ready-made ingredients, a main meal from basic ingredients, and cake or biscuits from basic ingredients). Frequency of preparation of main meals was also reported. Of 509 respondents, almost two-thirds reported cooking a main meal at least five times per week. Around 90 % reported being able to cook convenience foods, a complete meal from ready-made ingredient, and a main dish from basic ingredients without help. Socio-demographic differences in all markers of cooking skills were scattered and inconsistent. Where these were found, women and main food providers were most likely to report confidence with foods, techniques or dishes, and respondents in the youngest age (19-34 years) and lowest socio-economic group least likely. This is the only exploration of the prevalence and socio-demographic correlates of adult cooking skills using recent and population-representative UK data and adds to the international literature on cooking skills in developed countries. Reported confidence with using most cooking techniques and preparing most foods was high. There were few socio-demographic differences in reported cooking skills. Adult cooking skills interventions are unlikely to have a large population impact, but may have important individual effects

Acrylamide is a synthetic monomer with a wide scope of industrial applications, mainly as a precursor in the production of several polymers, such as polyacrylamide. The main uses of polyacrylamides are in water and wastewater treatment processes, pulp and paper processing, and mining and mineral processing. The announcement by the Swedish National Food Administration in April 2002 of the presence of acrylamide predominantly in heat-treated carbohydrate-rich foods sparked intensive investigations into acrylamide, encompassing the occurrence, chemistry, agricultural practices, and toxicology, in order to establish if there is a potential risk to human health from the presence of this contaminant in the human diet. The link of acrylamide in foods to the Maillard reaction and, in particular, to the amino acid asparagine has been a major step forward in elucidating the first feasible chemical route of formation during the preparation and processing of food. Other probably minor pathways have also been proposed, including acrolein and acrylic acid. This review addresses the analytical and mechanistic aspects of the acrylamide issue and summarizes the progress made to date by the European food industries in these key areas. Essentially, it presents experimental results generated under laboratory model conditions, as well as under actual food processing conditions covering different food categories, such as potatoes, biscuits, cereals, and coffee. Since acrylamide formation is closely linked to food composition, factors such as the presence of sugars and availability of free amino acids are also considered. Many new findings that contribute towards a better understanding of the formation and presence of acrylamide in foods are presented. Many national authorities across the world are assessing the dietary exposure of consumers to acrylamide, and scientific projects have commenced to gather new information about the toxicology of acrylamide. These are expected to provide

Os resultados mostram que o novo ambiente competitivo, deflagrado pela desregulamentação setorial e pela abertura comercial, permitiu a intensificação da concorrência e restringiu o poder de mercado das maiores empresas. Os dois segmentos foram obrigados a seguir o processo de adequação às exigências do consumidor, como a melhoria da qualidade, o aumento da variedade e a redução nos preços dos produtos. Todo esse processo foi liderado pelas maiores empresas, que realizaram investimentos em tecnologia e em capacidade produtiva e aumentaram, gradualmente, suas participações no mercado. O resultado desses ajustamentos traduziu-se, portanto, em melhor desempenho econômico e em maior benefício para a sociedade.The present work aimed to evaluate the adjustments occurred in the food sector of biscuit and pastry in Brazil, from 1995 to 2001, using the Structure-Conduct-Performance model of the Industrial Organization theory. The results demonstrated that the new competitive environment, started by the non-regulation in the sector and by the commercial openness, allowed tougher competition and restrained the market power of the major industries. Both segments had to adjust themselves to the demands of the consumer in the market by improving the quality of their products, furnishing a wider variety and reducing their costs. The whole process was led by the major industries, which invested in technology and productive capacity and, continually, increased their participation in the market. Therefore, as a result of these adjustments, there has been an improvement in the economic performance and a greater benefit for society.

Full Text Available INTRODUCTION: Current education has been grounded on traditional teaching practices; in other words, learning is regarded as an accumulation of knowledge given by the teachers. Use of resources such as videos and games can raise the interest of teachers since they are an attractive and less traditional alternative. Nevertheless, the use of generating issues stands out as it may help teachers to develop contextualized lessons. According to Freire (1987, this is the starting point in the process of constructing knowledge, replacing traditional practices and questioning the student’s previous knowledge of Biochemistry. OBJECTIVES: Thus, the aim of this study was to prepare and present a lesson to a 12th grade class at IF Fluminense on carbohydrates, diabetes mellitus, and isomerism based on the theme “Diabetes Mellitus”. MATERIALS AND METHODS: In order to collect data and check the validity of the use of such methodology in classes of Biochemistry, we used procedures such as: presentation of a video made by the authors about diabetes, a styrofoam model of a hepatic cell and biscuit models to show its metabolic functioning regarding metabolism of carbohydrates, styrofoam and toothpick molecular models aimed at explaining isomerism among main hexoses and, to finish the process, a roulette game named “Spinning with Biochemistry”, adapted from the television show Roda a Roda Jequiti, presented by SBT network. In addition, students had a class based on the “Three Pedagogical Moments” methodology proposed by Delizoicov et al. (2007. DISCUSSION AND RESULTS: After this, students developed more grounded scientific concepts, making use of terms common in scientific language. This suggests that the use of a Generating Issues, in a class based on problem-solving methods supported by playful strategies, was a meaningful contribution to improve the understanding of scientific knowledge. CONCLUSION: This type of class grounded on less traditional

Insights into Near-Surface Structural Control of Hydrothermal Fluid Movement at Rabbit Creek Thermal Area, Yellowstone National Park

Recent geophysical imaging efforts at Yellowstone National Park have generated questions about the geologic controls of hydrothermal fluid movement within the parks thermal areas. Currently, faults and lava flow contacts are assumed to be the primary permeability pathways for deeper fluid migration to the surface. Although intuition dictates that these structures are responsible, few studies have definitively shown that this is true. Earlier geophysical imaging efforts of phase separation in Norris Geyser Basin have shown strong evidence for fractures and faulting conducting hydrothermal waters. However, no geologically mapped faults are at the surface to confirm these interpretations. Therefore, during the summer of 2017, UW surface geophysical data acquisition focused on understanding the geologic controls for a thermal area within the well-mapped Rabbit Creek Fault Zone (RCFZ). The RCFZ strikes N-S along the eastern edge of Midway Geyser Basin (i.e. the western edge of the Mallard Lake Dome) about 2.8 Km SE of Grand Prismatic spring. The section of the fault zone within the Rabbit Creek thermal area is exposed on the eastern valley wall and dips steeply to the west. Regardless at our site, this puts the two of the plateau rhyolites (i.e. the Biscuit Basin Flow and Mallard Lake flow) next to each other ( 100 m apart) with a small amount of overlying alluvial, glacial and hydrothermal deposits covering the actual fault trace. Interestingly, at least two mapped reverse faults from the Mallard Lake Dome trend NW-SE into the site and are interpreted to intersect to the RCFZ. At RCFZ, DC resistivity and seismic refraction profiling combined with Self-Potential, Magnetics, and Transient Electromagnetic soundings were acquired to provide images and in situ geophysical properties. These data highlight the variable fracturing and surface expressions of the hydrothermal fluids associated with the RCFZ and the NW trending fault zone associated with the Mallard Lake Dome

School health promotion has been shown to improve the lifestyle of students, but it remains unclear whether school-based programs can influence family health. We developed an innovative program that enables school children to act as change agents in promoting healthy lifestyles of their mothers. The objective of this study was to examine the effect of the child-initiated intervention on weight, physical activity and dietary habit of their mothers. A 12-month cluster randomized trial was conducted, with school as a cluster. Participants were mothers with grade 8 students, aged around 13 years, of 20 schools in Homagama, Sri Lanka. Students of the intervention group were trained by facilitators to acquire the ability to assess noncommunicable disease risk factors in their homes and take action to address them, whereas those of the comparison group received no intervention. Body weight, step count and lifestyle of their mothers were assessed at baseline and post-intervention. Multi-level multivariable linear regression and logistic regression were used to assess the effects of intervention on continuous and binary outcomes, respectively. Of 308 study participants, 261 completed the final assessment at 12 month. There was a significantly greater decrease of weight and increase of physical activity in the intervention group. The mean (95% confidence interval) difference comparing the intervention group with the control group was -2.49 (-3.38 to -1.60) kg for weight and -0.99 (-1.40 to -0.58) kg/m(2) for body mass index. The intervention group had a 3.25 (95% confidence interval 1.87-5.62) times higher odds of engaging in adequate physical activity than the control group, and the former showed a greater number of steps than the latter after intervention. The intervention group showed a greater reduction of household purchase of biscuits and ice cream. A program to motivate students to act as change agents of family's lifestyle was effective in decreasing weight and

Public health policies, including in Europe, are considering measures and recommendations to limit the intake of added or free sugars. For such policies to be efficient and monitored, a precise knowledge of the current situation regarding sugar intake in Europe is needed. This review summarizes published or re-analyzed data from 11 representative surveys in Belgium, France, Denmark, Hungary, Ireland, Italy, Norway, The Netherlands, Spain and the UK. Relative intakes were higher in children than in adults: total sugars ranged between 15 and 21% of energy intake in adults and between 16 and 26% in children. Added sugars (or non-milk extrinsic sugars (NMES), in the UK) contributed 7 to 11% of total energy intake in adults and represented a higher proportion of children's energy intake (11 to 17%). Educational level did not significantly affect intakes of total or added sugars in France and the Netherlands. Sweet products (e.g. confectionery, chocolates, cakes and biscuits, sugar, and jam) were major contributors to total sugars intake in all countries, genders and age groups, followed by fruits, beverages and dairy products. Fruits contributed more and beverages contributed less to adults' total sugars intakes than to children's. Added sugars were provided mostly by sweet products (36 to 61% in adults and 40 to 50% in children), followed by beverages (12 to 31% in adults and 20 to 34% in children, fruit juices excluded), then by dairy products (4 to 15% in adults and 6 to 18% in children). Caution is needed, however, as survey methodologies differ on important items such as dietary data collection, food composition tables or estimation of added sugars. Cross-country comparisons are thus not meaningful and overall information might thus not be robust enough to provide a solid basis for implementation of policy measures. Data nevertheless confirm that intakes of total and added sugars are high in the European countries considered, especially in children, and point to

The possibility that lifestyle changes may be shared by the family members of subjects with obesity attending cognitive-behavioral treatment (CBT) for weight loss has been scarcely evaluated. The purpose of this study was to measure the changes in body weight, lifestyle habits, and stage of change toward physical activity in the family members of 149 subjects with overweight/obesity enrolled into a weekly group CBT for weight management in the years 2007-2008. 230 adult (aged >18 years) family members (129 spouses, 72 children (43 female, 29 male), 29 with a different family relationship) completed a self-administered questionnaire at baseline and soon after the end of the completion of their relatives' program (approximately 6 months later). The questionnaire consisted of qualitative information regarding food choices, estimation of energy and food intake, self-report of height and weight, and motivation toward physical activity. At baseline, self-reported body mass index was normal in 115 cases, in the range 25 to 29.9 in 80 and ≥30 in 35. Following CBT of their relatives, the family members significantly reduced their average daily energy intake (-232 kcal/day; Pfood choices revealed a reduced average daily amount of energy from dressings (-40 kcal, Pbread (-58 kcal, P<0.001), breakfast biscuits (-23 kcal, P=0.005), chocolate (-7 kcal, P=0.024), and nonalcoholic beverages (fruit juices and carbonated drinks; -10 kcal; P=0.013), whereas fruit consumption was increased (+10 kcal; P=0.023). There was also a shift in the stage of change toward exercising. Body mass index changes of family members and CBT subjects were significantly correlated, mainly within spouses. In conclusion, CBT for weight loss positively influences the lifestyle habits of family members of participants, reducing energy intake and promoting a more favorable attitude toward physical activity.

Climate change can cause an increase in arid soils, warmer weather, and reduce water availability, which in turn can directly affect food security. This increases food prices and reduces the availability of food. Therefore, knowledge concerning the nutritional and technological potential of non-traditional crops and their resistance to heat and drought is very interesting. Pearl millet is known to produce small nutritious cereal grains, which can endure both heat and dry conditions, and is one of the basic cereals of several African and Asian countries. Although this species has been cultivated in Brazil for at least 50 years it is only used as a cover crop and animal feed, but not for human consumption. Nonetheless, pearl millet grains have a high potential as food for humans because they are gluten-free, higher in dietary fiber content than rice, similar in lipid content to maize and higher content of essential amino acids (leucine, isoleucine and lysine) than other traditional cereals, such as wheat and rye. In addition, the crop is low cost and less susceptible to contamination by aflatoxins compared to corn, for example. Most grains, including pearl millet, can be milled, decorticated, germinated, fermented, cooked and extruded to obtain products such as flours, biscuits, snacks, pasta and non-dairy probiotic beverages. Pearl millet also has functional properties; it has a low glycemic index and therefore it can be used as an alternative food for weight control and to reduce the risk of chronic diseases, such as diabetes. Thus, this review intends to show the potential of pearl millet as an alternative food security crop, particularly in countries, like Brazil, where it is not commonly consumed. Also this review presents different processes and products that have been already reported in the literature in order to introduce the great potential of this important small grain to producers and consumers.

Full Text Available Abstract Background Evidence supports that television food advertisements influence children’s food preferences and their consumption. However, few studies have examined the extent and nature of food marketing to children in low and middle income countries. This study aims to assess the nutritional quality of foods and beverages advertised on Mexican TV, applying the Mexican, World Health Organization (WHO European and United Kingdom (UKNPM nutrient profile models, before the Mexican regulation on food marketing came into effect. Methods We recorded 600 h on the four national public and free TV channels with the highest national ratings, from December 2012 to April 2013. Recordings were done for 40 randomly selected (week, weekend, school and vacation days, from 7 am to 10 pm. Nutritional information per 100 g/ml of product was obtained from the product labels or company websites. Results A total of 2,544 food and non-alcoholic beverage advertisements were broadcast, for 275 different products. On average, the foods advertised during cartoon programming had the highest energy (367 kcal and sugar (30.0 g content, while foods advertised during sport programming had the highest amount of total fat (9.5 g and sodium (412 mg content. More than 60 % of the foods advertised did not meet any nutritional quality standards. 64.3 % of the products did not comply with the Mexican nutritional standards, as compared with 83.1 % and 78.7 % with WHO Europe and UKNPM standards, respectively. The food groups most frequently advertised were beverages (24.6 %, followed by chocolate and confectionery sugar (19.7 %, cakes, sweet biscuits and pastries (12.0 %, savory snacks (9.3 %, breakfast cereals (7.1 %, ready-made food (6.4 % and dairy products (6.0 %. Conclusion The majority of foods and beverages advertised on Mexican TV do not comply with any nutritional quality standards, and thus should not be marketed to children. The nutritional quality

Background The cultivated bread wheat (Triticum aestivum L.) possesses unique flour quality, which can be processed into many end-use food products such as bread, pasta, chapatti (unleavened flat bread), biscuit, etc. The present wheat varieties require improvement in processing quality to meet the increasing demand of better quality food products. However, processing quality is very complex and controlled by many genes, which have not been completely explored. To identify the candidate genes whose expressions changed due to variation in processing quality and interaction (quality x development), genome-wide transcriptome studies were performed in two sets of diverse Indian wheat varieties differing for chapatti quality. It is also important to understand the temporal and spatial distributions of their expressions for designing tissue and growth specific functional genomics experiments. Results Gene-specific two-way ANOVA analysis of expression of about 55 K transcripts in two diverse sets of Indian wheat varieties for chapatti quality at three seed developmental stages identified 236 differentially expressed probe sets (10-fold). Out of 236, 110 probe sets were identified for chapatti quality. Many processing quality related key genes such as glutenin and gliadins, puroindolines, grain softness protein, alpha and beta amylases, proteases, were identified, and many other candidate genes related to cellular and molecular functions were also identified. The ANOVA analysis revealed that the expression of 56 of 110 probe sets was involved in interaction (quality x development). Majority of the probe sets showed differential expression at early stage of seed development i.e. temporal expression. Meta-analysis revealed that the majority of the genes expressed in one or a few growth stages indicating spatial distribution of their expressions. The differential expressions of a few candidate genes such as pre-alpha/beta-gliadin and gamma gliadin were validated by RT

Full Text Available Khorasan wheat is an ancient grain with previously reported health benefits in clinically healthy subjects. The aim of this study was to examine whether a replacement diet, thereby substituting all other cereal grains, with products made with organic khorasan wheat could provide additive protective effects in reducing lipid, oxidative and inflammatory risk factors, in patients with Acute Coronary Syndromes (ACS in comparison to a similar replacement diet using products made from organic modern wheat. A randomized double-blinded crossover trial with two intervention phases was conducted on 22 ACS patients (9 F; 13 M. The patients were assigned to consume products (bread, pasta, biscuits and crackers made either from organic semi-whole khorasan wheat or organic semi-whole control wheat for eight weeks in a random order. On average, patients ingested 62.0 g dry weight (DW day−1 khorasan or control semolina; and 140.5 g DW day−1 khorasan or control flour, respectively. An eight-week washout period was implemented between the respective interventions. Blood analyses were performed both at the beginning and end of each intervention phase; thereby permitting a comparison of both the khorasan and control intervention phases, respectively, on circulatory risk factors for the same patient. Consumption of products made with khorasan wheat resulted in a significant amelioration in total cholesterol (−6.8%, low-density lipoprotein cholesterol (LDL-C (−8.1% glucose (−8% and insulin (−24.6% from baseline levels, independently of age, sex, traditional risk factors, medication and diet quality. Moreover, there was a significant reduction in reactive oxygen species (ROS, lipoperoxidation of circulating monocytes and lymphocytes, as well as in the levels of Tumor Necrosis Factor-alpha. No significant differences from baseline in the same patients were observed after the conventional control wheat intervention phase. The present results suggest that a

Pre-harvest sprouting (PHS) is an important cause of quality loss in many cereal crops and is particularly prevalent and damaging in wheat. Resistance to PHS is therefore a valuable target trait in many breeding programs. The Phs-A1 locus on wheat chromosome arm 4AL has been consistently shown to account for a significant proportion of natural variation to PHS in diverse mapping populations. However, the deployment of sprouting resistance is confounded by the fact that different candidate genes, including the tandem duplicated Plasma Membrane 19 ( PM19 ) genes and the mitogen-activated protein kinase kinase 3 ( TaMKK3-A) gene, have been proposed to underlie Phs-A1 . To further define the Phs-A1 locus, we constructed a physical map across this interval in hexaploid and tetraploid wheat. We established close proximity of the proposed candidate genes which are located within a 1.2 Mb interval. Genetic characterization of diverse germplasm used in previous genetic mapping studies suggests that TaMKK3-A , and not PM19 , is the major gene underlying the Phs-A1 effect in European, North American, Australian and Asian germplasm. We identified the non-dormant TaMKK3-A allele at low frequencies within the A-genome diploid progenitor Triticum urartu genepool, and show an increase in the allele frequency in modern varieties. In United Kingdom varieties, the frequency of the dormant TaMKK3-A allele was significantly higher in bread-making quality varieties compared to feed and biscuit-making cultivars. Analysis of exome capture data from 58 diverse hexaploid wheat accessions identified fourteen haplotypes across the extended Phs-A1 locus and four haplotypes for TaMKK3-A . Analysis of these haplotypes in a collection of United Kingdom and Australian cultivars revealed distinct major dormant and non-dormant Phs-A1 haplotypes in each country, which were either rare or absent in the opposing germplasm set. The diagnostic markers and haplotype information reported in the study will
