    Cattle feed is at the beginning of the food chain in the 'farm-to-fork' model and might serve as a source of contamination with pathogenic bacteria. Heat treatment is one of the most effective methods utilized to ensure the microbial safety of feeds. In this work, the thermal resistance of Salmonella enterica, Escherichia coli and Staphylococcus aureus isolated from vegetable feed ingredients was investigated in phosphate-buffered saline (PBS) and in cattle feed. Mean D values calculated in PBS ranged from 34.08 to 5.70 min at 55 °C, decreasing to 0.37 and 0.22 min at 65 °C for E. coli and S. enterica, respectively. No relationship was found between thermoresistance and source of isolation. D values in feed were calculated from the adjustment of two nonlinear models to the inactivation data. Thermal resistance of E. coli and S. enterica in cattle feed showed similar results to liquid medium; however, a fivefold increment of S. aureus thermoresistance in feed was observed. Our results also revealed an increase of microbial thermoresistance with the mean feed particle diameter. These results provide relevant information for improvement in the safety of cattle feed regarding its process conditions (i.e. time, temperature and particle size). © 2013 Society of Chemical Industry.

    Full Text Available There are significant environmental, economic and social factors favoring the reutilization of fruit and vegetable processing co-products in farm animal nutrition. Current evidence shows that fruit and vegetable processing co-products can be effectively used in farm animal nutrition as functional feed ingredients for the production of food products of improved quality. These ingredients comply with consumer requests for the production of “clean,” “natural” and “eco/green” label food products. The main parameters affecting extensive application of fruit and vegetable processing by-/co-products as functional feed ingredients in livestock nutrition are related to animal factors, logistics, and commercial value. Further research is needed to enable the commercial application of these products to livestock nutrition.

    Positive effects of yeast concentrate on immunity and performance of weaned piglets have been reported. However, the effects on innate immunity were not examined. Natural antibodies (NAb) are part of innate immunity and have been related to health and survival in fish, poultry, rodents, and man. Yeast cell walls may also affect innate immunity of weaned piglets. We studied the effect of Nuklospray ProHealth containing a spray dried blend of dairy-based feed ingredients, vegetable fats, and processed yeast cell walls as protein source on NAb levels and performance of weaned piglets. A total of 120 piglets weaned at 28 d of age were assigned 2 treatments comprising a control diet and an experimental diet with the test product. Piglets were housed in groups of 6 during the first 4 weeks after weaning. Blood samples of 20 healthy nonmedicated piglets per treatment were taken at days 0, 14, and 28 after weaning and analyzed for NAb levels binding keyhole limpet hemocyanin by an indirect ELISA procedure. Performance parameters also were determined. Overall, the experimental diet tended to improve feed intake (574 vs. 522 g/d; P < 0.1), ADG (449 vs. 412 g/d; P < 0.1), and final BW (21.4 vs. 20.3 kg; P = 0.08) compared to the control diet. No differences were found in feed conversion ratio or fecal score. At day 0, no differences in NAb levels were found, but on day 14 after weaning, NAb levels of piglets fed the experimental diet were significantly higher than of piglets fed the control diet (2.05 vs. 1.70; P < 0.05). On day 28 after weaning no differences were found. These results indicate that day 14 postweaning levels of NAb as a parameter of innate immunity were improved and indicate a tendency for improvement of postweaning performance of piglets fed diets supplemented with Nuklospray ProHealth.

    In the framework of sustainability and a circular economy, new ingredients for feed are desired and, to this end, initiatives for implementing such novel ingredients have been started. The initiatives include a range of different sources, of which insects are of particular interest. Within the European Union, generally, a new feed ingredient should comply with legal constraints in terms of 'yes, provided that' its safety commits to a range of legal limits for heavy metals, mycotoxins, pesticides, contaminants, pathogens etc. In the case of animal proteins, however, a second legal framework applies which is based on the principle 'no, unless'. This legislation for eradicating transmissible spongiform encephalopathy consists of prohibitions with a set of derogations applying to specific situations. Insects are currently considered animal proteins. The use of insect proteins is a good case to illustrate this difference between a positive, although restricted, modus and a negative modus for allowing animal proteins. This overview presents aspects in the areas of legislation, feed safety, environmental issues, efficiency and detection of the identity of insects. Use of insects as an extra step in the feed production chain costs extra energy and this results in a higher footprint. A measure for energy conversion should be used to facilitate the comparison between production systems based on cold- versus warm-blooded animals. Added value can be found by applying new commodities for rearing, including but not limited to category 2 animal by-products, catering and household waste including meat, and manure. Furthermore, monitoring of a correct use of insects is one possible approach for label control, traceability and prevention of fraud. The link between legislation and enforcement is strong. A principle called WISE (Witful, Indicative, Societal demands, Enforceable) is launched for governing the relationship between the above-mentioned aspects.

    The purpose of this study was to assess the occurrence of non-typhoidal Salmonellae and Enterobacteriaceae counts in raw ingredients and compound feeds sampled from feed mills manufacturing pig diets. Between November 2012 and September 2013, feed ingredients (n=340) and compound pig feed (n=313) samples were collected from five commercial feed mills and one home compounder at various locations throughout Ireland. Feed ingredients included cereals, vegetable protein sources and by-products of oil extraction and ethanol production. The compound feeds included meal and pelleted feed for all stages of pig production. Samples were analysed for Salmonella using standard enrichment procedures. Recovered isolates were serotyped, characterised for antibiotic resistance and subtyped by multi locus variance analysis (MLVA). Total Enterobacteriaceae counts were also performed. Salmonella was recovered from 2/338 (0.6%) ingredients (wheat and soybean meal), at two of the six mills. Salmonella was also detected in 3/317 (0.95%) compound feeds including pelleted feed which undergoes heat treatment. All isolates recovered from feed ingredient and compound feed samples were verified as Salmonella enterica subsp. enterica serotype (4,[5],12:i:-) that lack the expression of flagellar Phase 2 antigens representing monophasic variants of Salmonella Typhimurium (4,[5],12:i:-). Isolates exhibited resistance to between two and seven antimicrobials. Two distinct MLVA profiles were observed, with the same profile recovered from both feed and ingredients, although these did not originate at the same mill. There was no relationship between the occurrence of Salmonella and a high Enterobacteriaceae counts but it was shown that Enterobacteriaceae counts were significantly lower in pelleted feed (heat treated) than in meal (no heat treatment) and that Enterobacteriaceae counts would be very useful indicator in HACPP programme. Overall, although the prevalence of Salmonella in pig feed and feed

    Full Text Available Development of local chicken production based on local feed ingredient is in line with the vision of Indonesian goverment to fulfill meat and egg national requirement based on local resources. There are two big problem which become stumblingblock in developing local chicken production. The first problem is the difficulty to get day old chick of local chicken. This problem can be solved by integrating breeder institutions belong to goverment with research institution and with local chicken producer association. The second problem is the low performance of local chicken. To improve local chicken performance, it can be done by improving the breed, feed and management. Several research results show that good performance of local chicken were obtained by inclusion of local feed ingredients in the ration. Therefore, development of local chicken production based an local feed resources can be applied.

    Full Text Available Perspective direction of the Volga-Caspian basin fisheries is increasing the productivity of aquaculture production which requires the availability of sufficient quantities of feed. The cutting waste of carp and crucian carp, crayfish processing (cephalothorax, wheat bran, soy isolate, freshwater plants – pondweed perfoliate, fish-vegetable ration, produced feeding staffs have been investigated. In researching samples of manufactured pelleted feeds the standard methods adopted in the animal feed industry have been used. The number of nitrogen-free extractives and energy value has been determined by calculation. The composition of fish-vegetable ration has been worked out. Some manufacturing inspection of fish-vegetable feed technology using proofing process has been carried out. The possibility of manufacturing on the basis of crushed fish waste of the company LLC "VES" and dry ingredients of fish-vegetable feed has been determined; the output of feed at water content of not more than 10 % is 43 % of feed mix based on the mass of directed waste equal to 84 %. The pilot batch of dry fish-vegetable feed has been investigated to establish quality indicators. It has been determined that fish-vegetable feed meets the requirements of GOST 10385–2014 "Combined feeding staffs for fishes. General specifications" as for main quality indicators and refers to economic grower for catfish and carp fish weighing more than 50 g. This reveals good palatability of the experimental batch of floating feed by carp fish species and African catfish. Thus, fish-vegetable feed manufacturing technology can be implemented in the production for processing secondary raw materials: waste from butchering fish by grinding, cooking, mixing with selected vegetable fillings which is waste of flour or grain processing industries and freshwater plants mowed annually during the reclamation works on the Volga delta.

    Full Text Available A study was conducted to determine the presence of aflatoxins in finished poultry feed from manufacturing companies, feed ingredients, and poultry feed at the point of sale. Two collections were made. In the first collection, samples of the finished feed and feed ingredients were analyzed by high-performance liquid chromatography (HPLC. For the second collection, all samples were analyzed by ELISA while a subset was analyzed by HPLC. Of the 27 samples of finished feed, five samples had aflatoxin concentrations greater than the United States Food and Drug Administration (USFDA and European Union Commission (EUC maximum tolerable limit of 20 µg/kg, while for the feed ingredients, three of the 30 samples of feed ingredients exceeded the limit. Of the 93 samples of finished feed purchased from retailers, five samples had aflatoxin concentrations greater than the maximum tolerable limit. This survey indicates that most of the samples were below the maximum regulatory limit and maintained quality up to the point of sale for 2015 and 2016. However, given that some samples were above the limit, there is a need to monitor the production and marketing chain to ensure that the quality of the finished feed is not compromised.

    Full Text Available This study investigates the methane and carbon dioxide gas production, dry matter degradation, and final pH values obtained during the in vitro incubation of corn grain, soybean hulls, citrus pulp, corn silage, and crude glycerin. Experiments were performed using a randomized block design with four incubation periods. Each period featured four replicates per ingredient and four blanks, totaling 16 repetitions per ingredient. The lowest total amount of produced gas (37.96 mL gincubated DM-1 and the lowest final pH value (4.95 were obtained for crude glycerin (P < 0.05, which, however, exhibited the highest (P < 0.05 DM degradation. Citrus pulp produced the largest amount (P < 0.05 of CH4 per gram of incubated DM (13.56 mL g-1. However, when methane production was expressed per gram of degraded feed, the ingredients with lower degradation values, such as soybean hulls and corn silage, produced more CH4 per gram of degraded DM. Citrus pulp and corn grain produced more (P < 0.05 CO2 per gram of incubated DM. However, per gram of degraded food, citrus pulp produced the largest amount of CO2 (P < 0.05. Crude glycerin and corn grain produced less methane (per gram of degraded feed than citrus pulp, soybean hulls, and corn silage. Differentiation of ingredients based on their methane production ability is important to express methane production per unit degraded food mass.

    This work presents current information on the presence of aflatoxins (AFs) and zearalenone (ZEN) in feed and feed ingredients from Punjab, Pakistan. The 105 samples tested were concentrated feed, i.e., cotton seed meal (18 samples) and soybean meal (14), and feed ingredients, i.e., crushed corn (17), crushed wheat (15), barley (17). and poultry feed (24). Samples were analyzed using high-performance liquid chromatography equipped with a fluorescence detector. Analysis revealed that 69 of 105 samples were contaminated with AFs, and the highest mean concentrations of AFB1 (6.20 μg/kg) and total AFs (9.30 μg/kg) were found in poultry feed samples. The mean total AF concentrations ranged from the limit of quantification to 165.5 μg/kg. However, 75 of the 105 samples were positive for ZEN. The highest mean concentration (19.45 μg/kg) was found in poultry feed samples. The mean ZEN concentrations were 0.15 to 145.30 μg/kg. The prevalence of AFs and ZEN was high in feed and feed ingredients and needs urgent attention.

Were used: popcorn grain, sorghum, millet, rice colored and purple corn grinded (0.5% added to the diet, substituting grind corn and coarse limestone sieved through sieve nº 10 ABNT with 2 mm (added in 0.5% in the diet, substituting finely ground limestone. Microtracer F-Red was used as a method of reference. It was used a Y-type mixer (capacity of 5,000 cm3, and produced 1 kg of feed per repetition. It was adopted six mixing times (10 seconds, 1, 6, 11, 16 and 21 minutes and five particle size of corn (386, 513, 610, 731 and 839 ?m, amounting 30 treatments with three repetitions for each treatment. Where collected 12 samples, for each replicate, to measurement of the markers and determination of the coefficient of variation (CV. A quadratic effect with minimum point for the CV was observed for all markers with the increasing of the mixing time. There was no effect of the particle size of corn for the coefficients of variation of coarse limestone and millet. There was a quadratic response of the particle size of corn for the coefficients of variation of purple corn and popcorn grain and linear effect for the colored rice, sorghum and reference method. The particle size of corn changed the time needed to reduce the CV of the markers: colored rice, milled purple corn, popcorn, sorghum and microtracer. The use of alternative markers has shown that it is a promising tool for the determination of the optimum mixing time, especially millet and limestone, that showed the highest correlations with the reference method.

    Animal feed as a source of infection to food producing animals is much debated. In order to increase our present knowledge about possible feed transmission it is important to know that the present isolation methods for Salmonella are reliable also for feed materials. In a comparative study the ability of the standard method used for isolation of Salmonella in feed in the Nordic countries, the NMKL71 method (Nordic Committee on Food Analysis) was compared to the Modified Semisolid Rappaport Vassiliadis method (MSRV) and the international standard method (EN ISO 6579:2002). Five different feed materials were investigated, namely wheat grain, soybean meal, rape seed meal, palm kernel meal, pellets of pig feed and also scrapings from a feed mill elevator. Four different levels of the Salmonella serotypes S. Typhimurium, S. Cubana and S. Yoruba were added to each feed material, respectively. For all methods pre-enrichment in Buffered Peptone Water (BPW) were carried out followed by enrichments in the different selective media and finally plating on selective agar media. The results obtained with all three methods showed no differences in detection levels, with an accuracy and sensitivity of 65% and 56%, respectively. However, Müller-Kauffmann tetrathionate-novobiocin broth (MKTTn), performed less well due to many false-negative results on Brilliant Green agar (BGA) plates. Compared to other feed materials palm kernel meal showed a higher detection level with all serotypes and methods tested. The results of this study showed that the accuracy, sensitivity and specificity of the investigated cultural methods were equivalent. However, the detection levels for different feed and feed ingredients varied considerably.

Methods A total of 443 feed ingredients, including 220 corn, 24 wheat, 24 domestic distillers dried grains with soluble (DDGS, 55 bran, 20 wheat shorts and red dog, 37 imported DDGS, 34 corn germ meal and 29 soybean meal as well as 127 complete feeds including 25 pig complete feed (powder, 90 pig complete feed (pellet, six duck complete feed and six cattle complete feed were randomly collected from different Province in China, respectively, by high-performance chromatography in combined with UV or fluorescence analysis. Results The incidence rates of AFB1, ZEN and DON contamination of feed ingredients and complete feeds were 80.8, 92.3 and 93.9 %, respectively. The percentage of positive samples for DON ranged from 66.7 to 100 %. Domestic DDGS and imported DDGS presented the most serious contamination AFB1, ZEN and DON contamination levels of feeds ranged from 61.5 to 100 %, indicated that serious contamination over the studied 3-year period. Conclusion The current data provide clear evidence that AFB1, ZEN and DON contamination of feed ingredients and complete feeds in different Province in China is serious and differs over past 3-year. The use of corn, domestic DDGS, imported DDGS and corn germ meal, which may be contaminated with these three mycotoxins, as animal feed may triggered a health risk for animal. Feeds are most contaminated with DON followed by ZEN and AFB1. Mycotoxins contamination in feed ingredients and complete feeds should be monitored routinely in China.

Materials and Methods: Chromatography was performed on HPTLC silica gel 60 F 254, aluminum sheets by CAMAG automatic TLC sampler 4, with mobile phase condition chloroform:acetone:water (28:4:0.06. Extraction of aflatoxin B1 from samples was done as per AOAC method and screening and quantification done by HPTLC Scanner 4 under wavelength 366 nm. Results: A total of 97 livestock feed (48 and feed ingredients (49 samples received from different livestock farms and farmers were analyzed for aflatoxin B1of which 29 samples were contaminated, constituting 30%. Out of 48 livestock compound feed samples, aflatoxin B1 could be detected in 16 samples representing 33%, whereas in livestock feed ingredients out of 49 samples, 13 found positive for aflatoxin B1 representing 24.5%. Conclusion: HPTLC assures good recovery, precision, and linearity in the quantitative determination of aflatoxin B1 extracted from Livestock compound feed and feed ingredients. As more number of feed and feed ingredients are contaminated with aflatoxin B1 which causes deleterious effects in both animal and human beings, so there is a need for identifying the source of contamination, executing control measures, enabling better risk assessment techniques, and providing economic benefits.

    The current European protein deficit is estimated as high as 70% of present needs. Because of the high protein content of their seeds, grain legumes are attractive candidates for lowering the deficiency in plant protein production. The objective of this work was to identify new sources of vegetable protein that would reduce our high dependence of soy, the main source of protein in the manufacture of feedstuffs. To achieve this goal, we determined the proximate composition, the bioactive components, as well as the antinutritional factors present in the studied seeds. In general, the protein, fat and carbohydrates content of legume seeds studied were within the limits found in the literature. The bioactive compounds detected in all the seeds were α-galactosides, myoinositol phosphates, protease inhibitors and phenols. IP6 (phytic acid) was the main inositol phosphate form in all the samples. The highest protease inhibitors content was detected in both Lathyrus cicera cultivars. Vicia ervilia and L. cicera cultivars showed low haemagglutinating activity (20.4 HU/g). The γ-glutamyl-S-ethenyl-cysteine content in Vicia narbonensis was around 16.0 mg/g. Both L. cicera varieties presented similar β-N-oxalyl-L-α, β-diaminopropionic acid content (0.80 mg/g). The two V. ervilia varieties showed high canavanine concentration (1.93-5.28 mg/g). Vicine was only detected in V. narbonensis cultivars (0.3 mg/g). The biochemical characterization carried out in this study allows us to know the limits of inclusion of these minor crop seeds in feed formulations in order to replace the soybean. (Author)

    Full Text Available The current European protein deficit is estimated as high as 70% of present needs. Because of the high protein content of their seeds, grain legumes are attractive candidates for lowering the deficiency in plant protein production. The objective of this work was to identify new sources of vegetable protein that would reduce our high dependence of soy, the main source of protein in the manufacture of feedstuffs. To achieve this goal, we determined the proximate composition, the bioactive components, as well as the antinutritional factors present in the studied seeds. In general, the protein, fat and carbohydrates content of legume seeds studied were within the limits found in the literature. The bioactive compounds detected in all the seeds were α-galactosides, myoinositol phosphates, protease inhibitors and phenols. IP6 (phytic acid was the main inositol phosphate form in all the samples. The highest protease inhibitors content was detected in both Lathyrus cicera cultivars. Vicia ervilia and L. cicera cultivars showed low haemagglutinating activity (20.4 HU/g. The γ-glutamyl-S-ethenyl-cysteine content in Vicia narbonensis was around 16.0 mg/g. Both L. cicera varieties presented similar β-N-oxalyl-L-α, β-diaminopropionic acid content (0.80 mg/g. The two V. ervilia varieties showed high canavanine concentration (1.93-5.28 mg/g. Vicine was only detected in V. narbonensis cultivars (0.3 mg/g. The biochemical characterization carried out in this study allows us to know the limits of inclusion of these minor crop seeds in feed formulations in order to replace the soybean.

    Full Text Available A total of 52 samples of finished fish feeds and ingredients were collected from smallholder farmers in Kenya, Tanzania, Rwanda and Uganda, and analyzed. Culture and molecular techniques were used to identify fungal isolates from the feedstock, and mycotoxin profiles were determined using liquid chromatography–tandem mass spectrometry. The most prevalent fungal species recovered in the samples was Asperigillus flavus (54.5%. Other fungal species recovered from the samples were Aspergillus tamarii (9.1%, Mucor velutinosus (9%, Phoma sp. (6.1%, Aspergillus niger (6%, Eurotium rubrum (3% and Penicillium chrysogenum (3%. Fourteen mycotoxins were identified: aflatoxins B1, B2, G1 and G2, fumonisin B1 and B3, deoxynivalenol (DON and acetyldeoxynivalenol (sum of 3-ADONand 15-ADON, ochratoxin A, roquefortine C, alternariol, T-2 toxin, and nivalenol. DON (92.9%, aflatoxins (64.3% and fumonisins (57.1% were the most prevalent within locally manufactured feeds, while no contamination was found in imported feed. Samples from Kenya were the most contaminated with aflatoxin (maximum 806.9 μg·kg−1. The high levels of aflatoxin and trichothecene type A and B contamination found in this study point to potential risks to fish performance and to the health of consumers of the fish and derived products.

    Full Text Available Knowledge of canine food selection is critical for both the pet food industry and dog owners, since owners want quality foods that are palatable, while fulfilling their pet’s nutritional requirements. There are two common methods for assessing canine food preference: the two-pan test and the one-pan test. Neither test fully accounts for the complexity of the canine feeding experience nor do they provide applicable representations of canine feeding behavior in the home. The objectives of this study were to (1 determine whether dogs display a preference for animal ingredient-based diets when compared with vegetable ingredient-based diets and (2 examine whether dogs experience neophobia when presented with a novel diet. Eight adult Beagles (average age = 24 months, weighing 8–12 kg were individually fed each of four novel diets in a 4 × 4 replicated Latin square design, with 10-d treatment periods and four dietary treatments. Data were analyzed using a mixed model with repeated measures and significance was declared when p < 0.05. The diets were: animal and vegetable ingredient-based diets, and animal- and vegetable-based ingredients diluted with anhydrous α-d-glucose. The diluted diets were used for a larger study to determine true mineral digestibility. Dogs were fed twice per day (0800 and 1300 h. Behavioral observations were made by video on the first, and last 2 days of each 10-day treatment period of both a.m. and p.m. feedings. Time to consume feed, distraction, hesitation, level of anticipation pre-consumption, and interest post-consumption were recorded. Dogs experienced initial disruptive (neophobic effects of a novel diet. Neophobia was demonstrated by a decreased (slower rate of consumption, increased distraction during consumption of the diet, and increased hesitation on the first day of each new diet (p < 0.05. The level of interest post-consumption was highest when dogs consumed the animal

    Full Text Available To estimate nutrient and energy digestion with animal from in vitro variables it is necessary to control factors that may interfere on digestion such as: source and concentration of digestor substance, as well as the origin and processing of test ingredients. In this study there were performed five laboratory assays, two with poultry and finally regression equations were established based on variables generated with twelve vegetable ingredients. The results showed that there is greater solubility of proteins with NaOH than with KOH. On average, both alkali produced better discrimination of soluble protein with concentration of 0.02% (range of 68.61% in relation to a concentration of 0.2% (range of 37.97%. Considering interaction between alkali and concentration, the best discrimination on protein solubility was reached with NaOH at 0.02%. The methods of protein or fiber solubilization together with the chemical analysis showed significant results variation among ingredients and when they were used to estimate in vivo variables they produced good estimates. It was concluded that reliable digestion estimates for energy or amino acids from vegetable feed ingredients could be obtained from in vitro variables, when considering solubilities of protein and fiber with chemical analysis.Para estimar a digestão de nutrientes e de energia dos animais a partir de variáveis in vitro, é necessário controlar os fatores que interferem na digestão - origem e concentração da substância digestora - e ter conhecimento da fonte e do processo que envolve o ingrediente em teste. Neste trabalho, foram conduzidos cinco ensaios laboratoriais, dois com animais e, por fim, estabelecidas equações de regressão a partir das variáveis geradas com a utilização de 12 ingredientes vegetais. Os resultados mostraram que há maior solubilidade das proteínas com o NaOH que com o KOH e que, na média de ambos os álcalis, a concentração de 0,02% permite maior

    2013-10-25

    Cereal ingredients for animal feedstuffs may become contaminated by Salmonella on their farms of origin. This is often concentrated in multiple foci, owing to contamination by rodents and other wildlife which may be missed by routine sampling, and may involve serovars of particular public health significance, such as Salmonella Typhimurium (STM). The study examined such contamination in domestically-produced cereal ingredients in the United Kingdom. Cereal-producing farms with associated cattle or pig enterprises (43) and feedmills (6) were investigated, following the isolation of STM from their premises (feedmills) or STM DT104 from their livestock (farms) by routine surveillance. Cereal samples from feedmills yielded two STM isolates from the same premises, of the same phage types as were isolated from wild bird faeces at ingredient intake and product loading areas. Farm investigations identified numerous Salmonella serovars, including STM, on grain harvesting and handling equipment, in grain storage areas, and in wildlife samples. Mice were removed from one pig farm and shed Salmonella Derby and Salmonella Bovismorbificans for 10 months afterwards. Grain stores more than one kilometre away from livestock areas were rarely found to be contaminated with STM. The principal issues with Salmonella contamination of cereals appeared to be the use of livestock areas as temporary grain stores on cattle farms, and access to stored grain by wildlife and domestic animals.

    Full Text Available The opportunity of the presence of genetically modified organism (GMO forage crops in Indonesia is quite large. Although until now there is no single forage crop awarded safely crop in Indonesia, but several crop byproducts have been used as feed ingredient. The controversy over the presence of GMO plant cannot be avoided. There are a part of communities who could not accept the presence of GMO crops for some reasons. On the other hand, the producers claimed the advantages of the GMO crops such as reducing pesticide application, reducing cost of weeding, more tolerant to biotic and abiotic stresses, and increasing production, farmer’s income and welfare. For the opponent, the main concerns are environmental issues and the possibility of emerging diseases in animal as well as human being. The Biosafety Comission through Biosafety Technical Team has the authority to recommend whether GMO food or feed (and plants is safe or not safe to be consumed and grown in Indonesia after the assessment.

  18. Characterization of Dietary Energy in Swine Feed and Feed Ingredients: A Review of Recent Research Results

    Directory of Open Access Journals (Sweden)

    D. E. Velayudhan

    2015-01-01

    Full Text Available Feed is single most expensive input in commercial pork production representing more than 50% of the total cost of production. The greatest proportion of this cost is associated with the energy component, thus making energy the most important dietary in terms of cost. For efficient pork production, it is imperative that diets are formulated to accurately match dietary energy supply to requirements for maintenance and productive functions. To achieve this goal, it is critical that the energy value of feeds is precisely determined and that the energy system that best meets the energy needs of a pig is used. Therefore, the present review focuses on dietary supply and needs for pigs and the available energy systems for formulating swine diets with particular emphasis on the net energy system. In addition to providing a more accurate estimate of the energy available to the animal in an ingredient and the subsequent diet, diets formulated using the this system are typically lower in crude protein, which leads to additional benefits in terms of reduced nitrogen excretion and consequent environmental pollution. Furthermore, using the net energy system may reduce diet cost as it allows for increased use of feedstuffs containing fibre in place of feedstuffs containing starch. A brief review of the use of distiller dried grains with solubles in swine diets as an energy source is included.

    Feeds contribute highly to environmental impacts of livestock products. Therefore, formulating low-impact feeds requires data on environmental impacts of feed ingredients with consistent perimeters and methodology for life cycle assessment (LCA). We created the ECOALIM dataset of life cycle inventories (LCIs) and associated impacts of feed ingredients used in animal production in France. It provides several perimeters for LCIs (field gate, storage agency gate, plant gate and harbour gate) with homogeneously collected data from French R&D institutes covering the 2005-2012 period. The dataset of environmental impacts is available as a Microsoft® Excel spreadsheet on the ECOALIM website and provides climate change, acidification, eutrophication, non-renewable and total cumulative energy demand, phosphorus demand, and land occupation. LCIs in the ECOALIM dataset are available in the AGRIBALYSE® database in SimaPro® software. The typology performed on the dataset classified the 149 average feed ingredients into categories of low impact (co-products of plant origin and minerals), high impact (feed-use amino acids, fats and vitamins) and intermediate impact (cereals, oilseeds, oil meals and protein crops). Therefore, the ECOALIM dataset can be used by feed manufacturers and LCA practitioners to investigate formulation of low-impact feeds. It also provides data for environmental evaluation of feeds and animal production systems. Included in AGRIBALYSE® database and SimaPro®, the ECOALIM dataset will benefit from their procedures for maintenance and regular updating. Future use can also include environmental labelling of commercial products from livestock production.

    Full Text Available Cassava peel which is not used during cassava starch extraction is one of potential resources for animal feed. However, cassava peel has low level protein content, high level crude fiber, and high level of toxic cyanogenic compound. These problems limit the utilization of cassava peel as feed. Solid substrate fermentation using mold may be a solution process to increase its nutritional value and decrease toxic level of cassava peel. In this paper, matters that related with cassava peel fermentation process are subsequently described, namely: (i problems of cassava peel; (ii biodegradation and detoxification process; (iii solid state fermentation methods on cassava peel; (iv nutritional quality of fermented cassava peel; and (v application of fermented cassava peel in poultry feed. The fermented cassava peel application is compared with those of cassava root and waste (onggok. Addition of nitrogen inorganic in the fermentation process increases the mold growth and protein content of the product, while fiber and cyanogenic contents are decreased due to mold degradation activity. The fermentation process may be carried out using only the cassava peel as the substrate or mixed with wheat flour, using indigenous microbes, Aspergillus niger or a white rot fungus, Panus tigrinus as inoculum. As well as fermented cassava root and waste, fermented cassava peel can be used to substitute maize as poultry feed, although it is reported that the optimum substitution in broiler ration is only 10%.

    Full Text Available ABSTRACT: The aim of this study was to evaluate the sensory and physicochemical quality of colonial salamis added with vegetable-based curing ingredients as potential enhancers of quality products. Salamis were produced according to three treatments: (A Control: 0.1% curing salt; (B rosemary: 0.05% curing salt + 0.5% rosemary extract (RE; and (C RE+celery: 0.14% Veg 503 + 0.27% Veg 504 (sea salt plus celery, nitrate and nitrite supplies, respectively + 0.5% of RE. No significant differences were observed (P>0.05 among the three treatments for dry matter (DM, crude protein (CP, ash, ether extract (EE and gross energy (GE. Sensory analysis was performed by applying the preference test and multiple comparison between the three treatments. Salamis added with vegetable-based curing ingredients were sensory equivalent to conventional level of curing salts. Vegetable extracts allowed the development of the sensory features of salami and did not interfere in the fermentation process. Results suggested that the extracts can serve as effective natural curing ingredients for the ripening process and cured meat color as well as adequate shelf-life replacing the commercial curing salts in meat and meat products. After 30 days of ripening, salami from the control treatment (conventional levels of nitrite and nitrate and the treatments with added vegetable-based curing ingredients and low nitrite and nitrate content (RE and RE + celery were equivalent in sensory quality.

    Full Text Available The rates of microbiological safety of powdery vegetables, vegetable-milk compositions, compound desserts have been studied. No pathogenic germs (incl. salmonella, Escherichia coli, yeast, nonspore-forming bacteria B cereus have been detected in powdery vegetable samples. The number of mesophilic aerobic and facultative anaerobic microorganisms as well as amount of molds does not exceed safety index normalized by the legislation. Proteolytic microorganisms compose the basic microflora of powdery vegetables. Microbiological background of vegetable and milk basis is characterized by the presence of microorganisms differed by different resistance to the medium conditions – рН value, presence of oxygen and high temperatures impact. Enrichment of milk base by vegetable components necessitates to adjust the thermal effect regimes prescribed for milk treatment without additional ingredients. Introduction of vegetable ingredients into milk base is accompanied by polysemantic effect of high temperatures on microorganisms of polycomponent milk – vegetable base. On the one hand introduction of vegetable raw material into milk enhances inhibitory temperature effect on microbial cells due to transition of the medium рН into sour side; on the other hand presence of vegetable raw material particles protects microorganisms against sensitive effect of high temperature. Microflora of vegetable-milk compositions after heat treatment as well as ready-made desserts on their base was presented by spore-forming bacillus the number of which is correlated by their number in the initial raw material. In order to choose the optimal regime of heat treatment all processes running during heat treatment and particularly microbiological and physical-chemical degradation of polysaccharides of vegetables cell structures.

    Full Text Available Foods behave as non-Newtonian fluids, but little is known about how corn and soybean mix behave under viscometric flow. In order to characterize the rheological behavior of animal feed under viscometric flow, a 70:30 (mass:mass mixture of ground corn and soybean grains was submitted to a capillary rheometer at 3 different temperatures (80, 120, and 160 °C, different moisture levels (26.5 ± 0.08; 30.4 ± 0.31, and 33.4 ± 0.05%, and 4 shear rates (30.4; 72.9; 304.3, and 728.6/second. Different strain rates and die dimensions were used to obtain the target shear rates. The resulting data were fitted to Power Law, Casson, and Bingham models. Based on experimental data, water content, mass temperature, and the effects of shear rate on the apparent shear viscosity of corn-soy mix were fitted to a single expression (p < 0.001, R² = 0.93: η = 18,769.7 (y-0.86 e (-9.34 U + 935 T, where y is shear rate, U is sample moisture, and T is sample temperature in Kelvin scale.

    Full Text Available The study evaluated the replacement of bovine heart by gelatin in the feed training of carnivorous fish, using giant trahira (Hoplias lacerdae as an experimental model. A completely randomized design with four treatments and five repetitions was employed. The treatments were composed of wet ingredients beef heart (control, gelatin diluted in water, gelatin diluted in beef heart broth, and gelatin diluted in water mixed with fish meal. The fish (3.22±0.03 cm and 0.57±0.01 g were conditioned to accept industrialized diets by the technique of gradual feed ingredients transition in the diet. Gains in weight and length, efficiency of feed training, specific growth rate, cannibalism, mortality and survival rates were evaluated. There was significant difference in weight and length gains and specific growth rate, whereby the use of bovine heart gave the best results. Greater efficiency of feed training was observed for fish fed diets containing beef heart and gelatin diluted in water mixed with fish meal. The high survival rates and the absence of significant differences among treatments for rates of cannibalism, mortality and survival indicate the feasibility of using gelatin as a moist ingredient in the feed training of carnivorous fish.

    The DE values and digestible nutrients content of 6 diets were measured in 60-kg male growing pigs fed restricted amount of feed. Diets were prepared from 5 ingredients [wheat (Triticum aestivum), corn (Zea mays), barley (Hordeum vulgare), wheat bran, and soybean (Glycine max) meal; inclusion levels of ingredients were not correlated] with or without carbohydrose enzyme (Rovabio Excel AP; 3300 endo-β-1,4-xylanase visco units and 300 endo-1,3(4)-β-glucanase units/kg of feed; 150 g/t of feed) according to a 6 × 2 factorial arrangement; dietary NDF ranged from 10.6 to 20.1% of DM. Pigs (5 per treatment) were placed in metabolism cages that allowed total collections of feces and urine for 10 d after a 11-d adaptation. Samples of feed, urine, and feces were analyzed for GE, ash, and N. Digestibility of GE, N, and OM were calculated. The effects of diet and enzyme (Enz) were evaluated by ANOVA. In addition, the DE and digestible nutrient contents of ingredients were calculated by regression of nutritive values of diets on level of ingredient inclusions.

    Health messages can be tailored by applying different tailoring ingredients, among which personalisation, feedback and adaptation. This experiment investigated the separate effects of these tailoring ingredients on behaviour in auditory health persuasion. Furthermore, the moderating effect of self-efficacy was assessed. The between-participants design consisted of four conditions. A generic health message served as a control condition; personalisation was applied using the recipient's first name, feedback was given on the personal state, or the message was adapted to the recipient's value. The study consisted of a pre-test questionnaire (measuring fruit and vegetable intake and perceived difficulty of performing these behaviours, indicating self-efficacy), exposure to the auditory message and a follow-up questionnaire measuring fruit and vegetable intake two weeks after message exposure (n = 112). ANCOVAs showed no main effect of condition on either fruit or vegetable intake, but a moderation was found on vegetable intake: When self-efficacy was low, vegetable intake was higher after listening to the personalisation message. No significant differences between the conditions were found when self-efficacy was high. Individuals with low self-efficacy seemed to benefit from incorporating personalisation, but only regarding vegetable consumption. This finding warrants further investigation in tailoring research.

    As aquaculture becomes more important for feeding the growing world population, so too do the required natural resources needed to produce aquaculture feed. While there is potential to replace fish meal and fish oil with terrestrial feed ingredients, it is important to understand both the positive and negative implications of such a development. The use of feed with a large proportion of terrestrial feed may reduce the pressure on fisheries to provide feed for fish, but at the same time it may significantly increase the pressure on freshwater resources, due to water consumption and pollution in crop production for aquafeed. Here the green, blue and gray water footprint of cultured fish and crustaceans related to the production of commercial feed for the year 2008 has been determined for the major farmed species, representing 88% of total fed production. The green, blue and gray production-weighted average feed water footprints of fish and crustaceans fed commercial aquafeed are estimated at 1629 m3/t, 179 m3/t and 166 m3/t, respectively. The estimated global total water footprint of commercial aquafeed was 31-35 km3 in 2008. The top five contributors to the total water footprint of commercial feed are Nile tilapia, Grass carp, Whiteleg shrimp, Common carp and Atlantic salmon, which together have a water footprint of 18.2 km3. An analysis of alternative diets revealed that the replacement of fish meal and fish oil with terrestrial feed ingredients may further increase pressure on freshwater resources. At the same time economic consumptive water productivity may be reduced, especially for carnivorous species. The results of the present study show that, for the aquaculture sector to grow sustainably, freshwater consumption and pollution due to aquafeed need to be taken into account. Copyright © 2015.

    Evaluation of the genotoxic potential of food and feed ingredients is required in the development of new substances and for their registration. In addition to in vitro and in vivo assays, in silico tools such as expert alert-based and statistical models can be used for data generation. These in silico models are commonly used among the pharmaceutical industry, whereas the food industry has not widely adopted them. In this study, the applicability of in silico tools for predicting genotoxicity was evaluated, with a focus on bacterial mutagenicity, in vitro and in vivo chromosome damage assays. For this purpose, a test set of 27 food and feed ingredients including vitamins, carotenoids, and nutraceuticals with experimental genotoxicity data was constructed from proprietary data. This dataset was run through multiple models and the model applicability was analyzed. The compounds were generally within the applicability domain of the models and the models predicted the compounds correctly in most of the cases. Although the regulatory acceptance of in silico tools as single data source is still limited, the models are applicable and can be used in the safety evaluation of food and feed ingredients.

    An easy-to-operate membrane-based flow-through test for multiplex screening of four mycotoxins (zearalenone, deoxynivalenol, aflatoxin B1, and ochratoxin A) in a variety of cereal-based feed ingredients and compound feeds, such as wheat, barley, soybean, wheat bran, rice, rice bran, maize, rapeseed meal, and sunflower meal, and various types of complete feed (duckling feed, swine feed, broiler feed, piglet feed) was developed and validated. First, the antibodies were evaluated by enzyme-linked immunosorbent assay and then employed in the membrane rapid test. The cutoff levels for zearalenone, deoxynivalenol, aflatoxin B1, and ochratoxin A were 50, 200, 1, and 10 μg/kg, respectively, based on European regulations and consumers' requirements. As sample pretreatment, consecutive steps of extraction, dilution, solid-phase extraction by addition of C18 sorbent, and final filtration of supernatant were followed. Both the sample preparation and the analysis procedure were simple, cost-effective, and easy to perform on-site in a nonlaboratory environment. The impact of sample processing on the result of the experiment was investigated supported by experimental design. The validation procedure was performed on the basis of Commission Regulation 2006/401/EC. The numbers of false-positive and false-negative outcomes were <5%, going along with the Commission Decision 2002/657/EC. Liquid chromatography-tandem mass spectrometry was performed as a confirmatory technique.

    Awamori is produced by fermenting steamed indica rice. Awamori-pressed lees is a by-product of the Awamori production process. Tofu lees is a by-product of the Tofu production process. Research was conducted to test if dried Awamori-pressed lees and Tofu lees can be used as a mixed feed ingredient for raising male goats. Eighteen male kids were divided into three groups of six animals (control feed group (CFG), Awamori-pressed lees mixed feed group (AMFG), Tofu lees mixed feed group (TMFG)). The CFG used feed containing 20% soybean meal as the main protein source, while the AMFG and TMFG used feed mixed with 20% dried Awamori-pressed lees or dried Tofu lees. The groups were fed mixed feed (volume to provide 100 g/d increase in body weight) and alfalfa hay cubes (2.0 kg/d) twice a day (10:00, 16:00). Klein grass hay and water was given ad libitum. Hay intake was measured at 10:00 and 16:00. Body weight and size measurements were taken once a month. At the end of the experiment, a blood sample was drawn from the jugular vein of each animal and the carcass characteristics, the physical and chemical characteristics of loin were analyzed. DCP and TDN intakes in AMFG and TMFG showed no significant difference to the CFG. Cumulative measurements of growth in body weight and size over the 10 mo period in the AMFG and TMFG were similar to the CFG. Blood parameter values were similar to those in normal goats. Dressing carcass weight and percentages, and total weight of meat in the AMFG were similar to that in the CFG, but smaller in the TMFG. The compressed meat juice ratio was higher in both the TMFG and AMFG than the CFG. While the fat in corn, Awamori-pressed lees, and Tofu lees contains more than 50% linoleic acid, the loin fat in both the AMFG and TMFG was very low in linoleic acid due to the increase in the content of oleic acid, stearic acid, and palmitic acid. This indicates that feeding on AMF and TMF does not inhibit hydrogenation by ruminal microorganisms. As in

    Full Text Available Formulating the right feed based on the requirements of the fish species is the main solver to reduce the high cost of aquaculture production. In formulating suitable diet, factors such as the sustainability or availability of the feed sources used, quality of the feeds and price of raw materials, need to be taken into account as well so that the diets can be formulated at least cost. Low cost diets using local feed ingredients were formulated in pelleted and extruded forms and fed to juvenile African catfish, Clarias gariepinus, to determine their effect on the growth performance of the fish. Two formulations were tested: Diet A - Formula 1 MARDI and Diet B - Formula 2 MARDI, which were formulated to be iso-caloric and iso-nitrogenous with 32 % digestible protein and energy value of 14 MJ/kg. A commercial diet (Diet C was included as a control. At 15 wk of culture, fish fed diet C showed the highest growth performance in terms of weight gain, feed conversion ratio (FCR and specific growth rate (SGR. There were no significant differences (P>0.05 found among diets for weight gain and feed intake. However, FCR and SGR of Diet C were significantly better (P<0.05 compared to the experimental diets. The best FCR was recorded in Diet C at 1.17, followed by Diet A (1.42 and Diet B (1.46. Diet C also had the highest SGR with 1.99%/day followed by Diet B (1.70 and Diet A (1.67. Cost of both diets, A and B, was RM 2.50/kg compared to RM 3.50/kg for Diet C. Although the FCR of the commercial feed was lower than the experimental diets, the production cost of fish was RM4.11/kg for the commercial feed compared to RM 3.54-3.65/kg for the experimental diets. It is concluded that local feed ingredients can be used in formulating diets for catfish and they have no detrimental effect on the growth of African catfish.

    More than 1700 samples of forage grain, sunflower and soy-bean oil-seed meal and cakes, gluten, and compounded feeds were analyzed for citrinin by indirect ELISA with a minimum detectable level of 10 ppb. Out of 829 compounded feeds (rations and concentrates) 8.8 per cent samples were positive and the amount of citrinin ranged between 12 and 182 ppb. Only 4.5% of wheat and 3.6% of barley contained citrinin at 50-998 ppb. 1.9% of maize grain samples were positive at levels of 218-953 ppb. Among the other ingredients the highest incidence (28.9%) at the levels of 14-397 ppb was found for sunflower oil-seed meal and cakes. Three positive cases of 148 processed soy-bean samples contained citrinin in a range of 14-30 ppb.

    The presence and antimicrobial susceptibility of foodborne pathogens and indicator organisms in animal feed are not well understood. In this study, a total of 201 feed ingredient samples (animal byproducts, n=122; plant byproducts, n=79) were collected in 2002 and 2003 from representative rendering plants and the oilseed (or cereal grain) industry across the United States. The occurrence and antimicrobial susceptibility of four bacterial genera (Salmonella, Campylobacter, Escherichia coli, and Enterococcus) were determined. Salmonella isolates were further characterized by serotyping and pulsed-field gel electrophoresis (PFGE). None of the samples yielded Campylobacter or E. coli O157:H7, whereas Salmonella, generic E. coli, and Enterococcus were present in 22.9%, 39.3%, and 86.6% of samples, respectively. A large percentage (47.8%) of Salmonella-positive samples harbored two serovars, and the vast majority (88.4%) of Enterococcus isolates were E. faecium. Animal byproducts had a significantly higher Salmonella contamination rate (34.4%) than plant byproducts (5.1%) (pSalmonella isolates recovered, 27 serovars and 55 PFGE patterns were identified; all were pan-susceptible to 17 antimicrobials tested. E. coli isolates (n=131) demonstrated similar susceptibility to these antimicrobials except for tetracycline (15.3% resistance), sulfamethoxazole (7.6%), streptomycin (4.6%), ampicillin (3.8%), and nalidixic acid (1.5%). Enterococcus isolates (n=362) were also resistant to five of 17 antimicrobials tested, ranging from 1.1% to penicillin to 14.6% to tetracycline. Resistance rates were generally higher among isolates recovered from animal byproducts. Taken together, our findings suggest that diverse populations of Salmonella, E. coli, and Enterococcus are commonly present in animal feed ingredients, but antimicrobial resistance is not common. Future large-scale studies to monitor these pathogenic and indicator organisms in feed commodities is warranted.

    Plant ingredients and processed animal proteins (PAP) are suitable alternative feedstuffs for fish feeds in aquaculture practice, although their use can introduce contaminants that are not previously associated with marine salmon and gilthead sea bream farming. Mycotoxins are well known natural contaminants in plant feed material, although they also could be present on PAPs after fungi growth during storage. The present study surveyed commercially available plant ingredients (19) and PAP (19) for a wide range of mycotoxins (18) according to the EU regulations. PAP showed only minor levels of ochratoxin A and fumonisin B1 and the mycotoxin carry-over from feeds to fillets of farmed Atlantic salmon and gilthead sea bream (two main species of European aquaculture) was performed with plant ingredient based diets. Deoxynivalenol was the most prevalent mycotoxin in wheat, wheat gluten and corn gluten cereals with levels ranging from 17 to 814 and μg kg(-1), followed by fumonisins in corn products (range 11.1-4901 μg kg(-1) for fumonisin B1+B2+B3). Overall mycotoxin levels in fish feeds reflected the feed ingredient composition and the level of contaminant in each feed ingredient. In all cases the studied ingredients and feeds showed levels of mycotoxins below maximum residue limits established by the Commission Recommendation 2006/576/EC. Following these guidelines no mycotoxin carry-over was found from feeds to edible fillets of salmonids and a typically marine fish, such as gilthead sea bream. As far we know, this is the first report of mycotoxin surveillance in farmed fish species. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Due to concerns related primarily to allergic response and malabsorption, enteral nutrition therapy has traditionally relied on the use of elemental formulas in children with intestinal failure (IF). Blended food diets via a gastrostomy tube have been reported to improve feeding tolerance in pediatric populations receiving long-term enteral nutrition therapy. Complex macronutrients have been shown to stimulate intestinal adaptation in animal models. We report on our experience in children with IF who had an overall improvement in stool output when transitioned from an elemental formula to a tube feeding formula with real food ingredients (TFRF). Data were collected in a retrospective chart review of children with IF, >1 year of age, who were receiving enteral nutrition via continuous infusion, bolus feeding, or both. Indications for the TFRF trial were diarrhea or inconsistent stooling patterns. Ten children with a mean small bowel length of 48.3 cm were trialed on TFRF. Nine of 10 (90%) children tolerated the transition to 100% TFRF, of which 7 of 9 (78%) had their entire colon in continuity. The average age at successful transition was 29.2 months, and the average length of time to transition to 100% TFRF was 67.3 days. TFRF is well tolerated in children >1 year of age with IF; it also improves their stooling patterns. A commercially available TFRF is a cost-effective and nutritionally adequate means of providing nutrition to this patient population.

    Salmonella Typhimurium is a potential feed safety hazard in animal feed ingredients. Thermal mitigation of Salmonella spp. during rendering is effective but does not eliminate the potential for cross-contamination. Therefore, the objective of this experiment was to evaluate the effectiveness of chemicals to mitigate postrendering Salmonella Typhimurium ATCC 14028 contamination in rendered proteins over time. Treatments were arranged in a 6 × 4 factorial with six chemical treatments and four rendered protein meals. The chemical treatments included (i) control without chemical treatment, (ii) 0.3% commercial formaldehyde product, (iii) 2% essential oil blend, (iv) 2% medium chain fatty acid blend, (v) 3% organic acid blend, and (vi) 1% sodium bisulfate. The four rendered protein meals included (i) feather meal, (ii) blood meal, (iii) meat and bone meal, and (iv) poultry by-product meal. After matrices were chemically treated, they were inoculated with Salmonella Typhimurium ATCC 14028, stored at room temperature, and enumerated via plate counts on days 0, 1, 3, 7, 14, 21, and 42 postinoculation. The Salmonella concentration in ingredients treated with medium chain fatty acid and commercial formaldehyde were similar to one another (P = 0.23) but were 2 log lower than the control (P Salmonella concentrations than the control (P Salmonella mitigation, because all days except days 14 and 21 (P = 0.92) differed from one another. Rendered protein matrix also affected Salmonella stability, because concentrations in meat and bone meal and blood meal were similar to one another (P = 0.36) but were greater than levels in feather meal and poultry by-product meal (P Salmonella Typhimurium ATCC 14028, but their effectiveness was matrix dependent. Time and chemical treatment with medium chain fatty acids or a commercial formaldehyde product were most effective at mitigating Salmonella Typhimurium ATCC 14028 in rendered protein meals.

    Livestock production has a variety of environmental impacts such as greenhouse gas emissions, water pollution, acidification, and primary energy consumption. The demand for livestock products is expected to grow substantially, creating even more environmental pressure. The use of specialty feed ingredients (SFI) such as supplemented AA and phytase can reduce nutrient input into the system without compromising productivity and consequently can reduce emissions. The global change impact of using SFI in pig and broiler production systems in Europe and North and South America was studied. A life cycle assessment according to international standards (ISO 14040/44) analyzed contributions from producing SFI and animals to global change. Three different alternatives were analyzed. In addition, partial sensitivity analysis was conducted using 5 scenarios for each region for both production systems. Specialty feed ingredient supplementation in pig and broiler diets reduced greenhouse gas emissions (cradle to farm gate) by 56% and 54% in Europe, 17% and 15% in North America, and 33% and 19% in South America, respectively, compared to an unsupplemented diet. A total of 136 Mt CO equivalent (CO eq) was saved in 2012, rising to 146 Mt CO eq in 2050 on the basis of United Nations population projections. Considerable benefits of supplementation with SFI were apparent in European and South American diets when direct land use change was considered because of the reduced demand for soybean meal. The eutrophication potential of unsupplemented diets was reduced by up to 35% in pig and 49% in broiler production systems compared to supplemented alternatives. The acidification potential of supplemented strategies was reduced by up to 30% in pig and 79% in broiler production systems. The primary energy demand was similar in all alternatives, and this could be an area where the SFI industry can improve. Overall, SFI supplementation substantially reduced the global warming, eutrophication

    This experiment was conducted to determine standardized ileal amino acid digestibility (SIAAD) of commonly used feed ingredients in poultry diets in Pakistan. These feed ingredients included corn, rice broken (RB), rice polishings (RP), wheat bran (WB), sunflower meal (SFM), cottonseed meal (CSM), guar meal (GM), soybean meal (SBM) from India and Argentine and fish meal (FM). The SIAAD of each ingredient was determined in triplicate using 21-days-old broilers. Day-old male broiler chicks (Hubbard× Hubbard) were reared on corn-SBM based diet from 1 to 13 days and thereafter birds were fed experimental diets from day 14 to 21. Each diet was fed to 36 birds kept in six replicate cages, each cage had six birds. In cereals, the SIAAD of corn’s amino acid (AA) (90.1%) was similar (p>0.05) to RB (89.0%). Isoleucine (97.8%) and lysine (96.9%) were highly digestible AA in corn and RB, respectively. Among cereal-by products, WB’s SIAAD (76.9%) was same (p>0.05) as RP (71.9%). Arginine from WB (82.5%) and RP (83.2%) was highly digestible. However, threonine in WB (72.7%) and leucine in RP (69.6%) were the lowest digestible AAs. In plant protein meals, AAs from Argentine-SBM (85.1%) and Indian-SBM (83.4%) had higher (pprotein meals. However, SIAAD of SFM (77.1%) and CSM (71.7%) was intermediate while GM (60.3%) exhibited the lowest (pdigestible from indispensable AAs. In SFM, methionine (91.4%) SIAAD was the greatest. The average SIAAD of FM was 77.6%. Alanine from FM had the highest (84.0%) but cysteine (62.8%) had the lowest SIAAD. In conclusion, cereals i.e. corn and RB had higher (p0.05). The SBM from plant protein meals had higher (pprotein meals. PMID:26954227

    Sustained price increases for traditional cereal grain and protein meal feed commodities have forced the pork industry to consider the dietary inclusion of alternative feedstuffs. Crop seed may serve as feedstuffs but their demand as feedstock for human food, biofuel, and bioindustrial products has increased. Together with these products, coproducts such as distillers dried grains with solubles, wheat millrun, and canola meal are produced. As omnivores, pigs are ideally suited to convert these non-human-edible coproducts into high-quality food animal protein. Therefore, coproducts and other low-cost alternative feedstuffs such as pulses and oilseeds can be included in pig diets to reduce feed cost per metric ton of feed. However, inclusion of alternative feedstuffs in pig diets does not necessarily reduce feed cost per kilogram of gain. Therefore, the use of novel and existing feedstuffs in pig diets must be optimized following their characterization for energy and AA profile. Alternative feedstuffs generally have a high content of at least 1 of the following antinutritional factors (ANF): fiber, tannins, glucosinolates, and heat-labile trypsin inhibitors. Several methods can optimize nutrient use of pigs fed alternative feedstuffs by reducing effects of their ANF. These methods include 1) particle size reduction to increase nutrient digestibility, 2) dehulling or scarification to reduce tannin and fiber content of pulses and oilseeds, 3) air classification to create fractions that have a greater content of nutrients and lower content of ANF than the feedstock, 4) heat treatments such as extrusion, toasting, roasting, and micronization to reduce heat-labile ANF, 5) dietary supplementation with fiber-degrading enzymes or predigestion of fibrous feedstuffs or diets with fiber-degrading enzymes to increase dietary nutrient availability, and 6) formulation of diets based on bioavailable AA coefficients. In conclusion, the feeding of alternative ingredients may reduce

    Animal feeding practices in the United States have changed considerably over the past century. As large-scale, concentrated production methods have become the predominant model for animal husbandry, animal feeds have been modified to include ingredients ranging from rendered animals and animal waste to antibiotics and organoarsenicals. In this article we review current U.S. animal feeding practices and etiologic agents that have been detected in animal feed. Evidence that current feeding practices may lead to adverse human health impacts is also evaluated. We reviewed published veterinary and human-health literature regarding animal feeding practices, etiologic agents present in feed, and human health effects along with proceedings from animal feed workshops. Data were extracted from peer-reviewed articles and books identified using PubMed, Agricola, U.S. Department of Agriculture, Food and Drug Administration, and Centers for Disease Control and Prevention databases. Findings emphasize that current animal feeding practices can result in the presence of bacteria, antibiotic-resistant bacteria, prions, arsenicals, and dioxins in feed and animal-based food products. Despite a range of potential human health impacts that could ensue, there are significant data gaps that prevent comprehensive assessments of human health risks associated with animal feed. Limited data are collected at the federal or state level concerning the amounts of specific ingredients used in animal feed, and there are insufficient surveillance systems to monitor etiologic agents "from farm to fork." Increased funding for integrated veterinary and human health surveillance systems and increased collaboration among feed professionals, animal producers, and veterinary and public health officials is necessary to effectively address these issues.

    This research studied the extraction from Microcystis aeruginosa using hydrochloric acid method as a potentially valuable protein resource from eutrophic lakes. Amino acid composition, residual algal toxins, and heavy metals of the acidolysis product were studied. After 18 h of hydrochloric acid treatment, the product of M. aeruginosa contained 17 amino acids, 51.34% of total amino acid requirements, and 30.25% of the livestock and poultry essential amino acid (Eaa). The residual microcystin-LR (MC-LR) was 0.94 µg kg(-1), which was less than WHO drinking water limit of microcystins. The removal ratio of microcystins was higher than 99.99% during the process of hydrolysis. The concentration of heavy metals of the product was in compliance with feed standards. Furthermore, using Horn's method, Mouse Micronucleus Test and Sperm Shape Abnormality Test were conducted to study the forage safety of the product. Half lethal dose (LD50) of acidolysis product in mice was >9.09 g kg(-1) body weight, actually belonging to non-toxic grade. Every dose treatment did not significantly increase activities of alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and γ-glutamyltransferase (γ-GT). The results of both micronucleus test and sperm shape abnormality test were negative, which suggested the product with no mutagenicity and sperm malformation effects. This study indicated that the acidolysis product of M. aeruginosa was safe to be used as a feed ingredient. © 2015 by the Society for Experimental Biology and Medicine.

    Poultry wastes manure was diluted by adding the same amount of water 50-50 (w/v). They were then mixed with 10% molasses. The mixture was inoculated with a starter culture of Lactobacillus plantarum and Pediococcus acidolactici, and incubated at 30{sup o}C for 10 days. Changes in nutritional quality and biochemical properties (pH, total nitrogen, total volatile nitrogen, non protein nitrogen, carbohydrates and ash) were determined for the raw and the transformed product. In parallel, microbiological analyses, including standard plant count, enterobacteria and enterococci, were performed. Results indicated that the product obtained from the wastes fermentation showed low counts of enterobacteria and enterococci. Chemical determinations showed a net decrease of the pH to around 4.0 and the growth curve of the lactic acid bacteria showed the success of the acidification process. The total nitrogen was conserved in the product and the total volatile nitrogen was totally eliminated. The product was used for substituting some protein sources in a conventional formula used in laying feeding of three lots. Two formulae containing, respectively, 20% and 40% of the product was compared to the control (0%). The food consumption and laying performances were monitored for 30 days. The nutritional test indicted that the incorporation of the poultry manure silage of up to 40% gave laying performances similar to those obtained with the conventional formula. These results show that it is possible to transform poultry manure by controlled fermentation and that the product has an added value as a feed ingredient. (Author)

    Background: Due to a growing global aquaculture production, fish oil (FO) and fish meal (FM) are partly replaced with vegetable ingredients in aqua feed for Atlantic salmon. These replacements in the feed lead to an altered fatty acid composition in the salmon fillet. We aimed to investigate how...... levels of diacylglycerol (DAG), ceramides and arachidonic acid (AA)-derived oxylipins compared with mice fed WD-FO. In addition, C57BL/6J mice were fed fish oil-enriched diets with different carbohydrate sources, and we observed that sucrose dose-dependently abrogate the antiobesity effect of fish oil......%) of FO with different vegetable oils (VOs); rape seed oil (WDRO), olive oil (WD-OO) or soybean oil (WD-SO). These diets were given to C57BL/6J mice, and mice had higher hepatic lipid accumulation and lower insulin sensitivity when given WD-SO compared with WD-FO. Mice given WD-SO had higher hepatic...

    The present article describes the second part of a study investigating the effect of adding vegetables on the nutritional, physico-chemical, and oxidative properties of wheat bread, and specifically focuses on bread that does not contain oil as an added ingredient. Wheat flour breads fortified with freeze-dried carrot, tomato, beetroot or broccoli were developed and assessed for their nutritional composition, antioxidant potential, oxidative stability, and storage properties. Using a simulated in vitro model, the study also examined the impact of vegetable addition on the oxidative stability of macronutrients during gastro-intestinal digestion. Adding vegetables improved the nutritional and functional attributes of the oil-free breads. However, they demonstrated a lower antioxidant potential compared to their oil-containing counterparts. Similarly, the textural and storage properties of the oil-free vegetable breads were poorer compared to the oil-containing breads. As expected, in the absence of oil the oil-free breads were associated with lower lipid oxidation both in their fresh form and during gastro-intestinal digestion. Adding vegetables reduced protein oxidation in the fresh oil-free breads but had no effect during gastro-intestinal digestion. The impact of vegetables on macronutrient oxidation in the oil-free breads during digestion appears to be vegetable-specific with broccoli exacerbating it and the others having no effect. Of the evaluated vegetables, beetroot showed the most promising nutritional and physico-chemical benefits when incorporated into bread that does not contain added oil.

    The use of non-linear regression models in the analysis of biological data has led to advances in poultry nutrition. Spline or broken-line nonlinear regression models are commonly used to estimate nutritional requirements. One particular application of broken-line models is estimating the maximum safe level (MSL) of feed ingredients beyond which the ingredients become toxic, resulting in reduced performance. The objectives of this study were to evaluate the effectiveness of broken-line models (broken-line linear or BLL; and broken-line quadratic or BLQ) in estimating the MSL; to identify the most efficient design of feeding trials by finding the optimal number of ingredient levels and replications; and to re-estimate the MSL of various test ingredients reported in the nutrition literature for comparison purposes. The Maximum Ingredient level Optimization Workbook (MIOW) was developed to simulate a series of experiments and estimate the MSL and the corresponding descriptive statistics (SD, SE, CI, and R2). The results showed that the broken-line models provided good estimates of the MSL (small SE and high R2) with the BLL model producing higher MSL values as compared to the BLQ model. Increasing the number of experimental replications or ingredient levels (independently of each other) reduced the SE of the MSL with diminishing returns. The SE of the MSL was reduced with increasing the size (total pens) of the simulated experiments by increasing either the number of replications or levels or both. The evaluation of MSLs reported in the existing literature revealed that the multiple range procedure used to determine the MSL in several reports can both overestimate and underestimate the MSL compared to the results obtained by the broken-line models. The results suggest that the broken-line linear models can be used in lieu of the multiple range test to estimate the MSL of feed ingredients along with the corresponding descriptive statistics, such as the SE of the MSL.

    Full Text Available Objective An experiment was conducted to determine digestible energy (DE and metabolizable energy (ME of different byproduct feed ingredients fed to growing pigs, and to generate prediction equations for the DE and ME in feed ingredients. Methods Twelve barrows with an initial mean body weight of 31.8 kg were individually housed in metabolism crates that were equipped with a feeder and a nipple drinker. A 12×10 incomplete Latin square design was employed with 12 dietary treatments, 10 periods, and 12 animals. A basal diet was prepared to mainly contain the corn and soybean meal (SBM. Eleven additional diets were formulated to contain 30% of each test ingredient. All diets contained the same proportion of corn:SBM ratio at 4.14:1. The difference procedure was used to calculate the DE and ME in experimental ingredients. The in vitro dry matter disappearance for each test ingredient was determined. Results The DE and ME values in the SBM sources were greater (p<0.05 than those in other ingredients except high-protein distillers dried grains. However, DE and ME values in tapioca distillers dried grains (TDDG were the lowest (p<0.05. The most suitable regression equations for the DE and ME concentrations (kcal/kg on the dry matter [DM] basis in the test ingredients were: DE = 5,528–(156×ash–(32.4×neutral detergent fiber [NDF] with root mean square error = 232, R2 = 0.958, and p<0.001; ME = 5,243–(153 ash–(30.7×NDF with root mean square error = 277, R2 = 0.936, and p<0.001. All independent variables are in % on the DM basis. Conclusion The energy concentrations were greater in the SBM sources and were the least in the TDDG. The ash and NDF concentrations can be used to estimate the energy concentrations in the byproducts from oil-extraction and distillation processes.

    Full Text Available A mathematical model of the polydisperse medium mixing process reflects its stochastic features in the form of uneven distribution of phase elements on the time of their presence in apparatus, particle size, ripple retention of the apparatus, random distribution of the material and thermal phase flows of the working volume, heterogeneity of the medium physical- and chemical properties, complicated by chemical reaction. For the mathematical description of the mixing process of animal feed ingredients in the presence of chemical reaction the system of differential equations of Academician V.V. Kafarov was used. Proposed by him hypothesis based on the theory of Markov’s processes stating that "any multicomponent mixture can be considered as the result of an iterative process of mixing the two components to achieve the desired uniformity of all the ingredients in the mixture" allows us to consider a process of mixing binary composition in a paddle mixer in the form of differential equations of two ingredients concentration numerous changes until it becomes a homogenous mixture. It was found out that the mixing process of the two-component mixture is determined in a paddle mixer with a constant mixing speed and a limit (equilibrium dispersion of the ingredients in the mixture i.e. with its uniformity. Adjustment of the model parameters was carried out according to the results of experimental studies on mixing the crushed wheat with metallomagnetic impurity, which was a key (indicator component. According to the best values of the constant of the continuous mixing speed and the equilibrium disperse values of the ingredients contents, the mathematical model parameters identification was carried out. The results obtained are used to develop a new generation mixer design.

    Objective: To investigate fungi contamination and the natural occurrence of mycotoxins in corn feed ingredients collected from China. Methods: A total of 94 corn feed ingredient samples were collected from 8 Chinese provinces(i.e., Anhui, Hebei, Heilongjiang, Jilin, Jiangsu, Liaoning, Inner Mongolia, and Shandong)in February 2014. A tandem ultra-performance liquid chromatographymass spectrometry method was used for simultaneous detection of twelve kinds of mycotoxins, including aflatoxin(AF), type A and type B tricothecenes, and zearalenone(ZEN). Contaminated fungi were also identified and counted. Results: AF was detected in 36.2%(34/94)of samples; the concentration of AFB1 was the highest in the four AFs with the range: 0.3~181.3 μg/kg; and then followed by AFB2(range: 1.0-74.3 μg/kg). There were 7 samples(7.5%)with AFB1 concentrations higher than the tolerance limit of 50 μg/kg. The concentration of type A tricothecenes in all samples was lower(0.1-10.5 μg/kg). DON had the most serious contamination than other kind of type B tricothecenes(range: 0.7-606.6 μg/kg; median: 66.3 μg/kg). The DON concentration in all samples was below the tolerance limit of 1 000 μg/kg. ZEN was detected in 76.6%(72/ 94)of samples(median: 36.9 μg/kg), with 3 samples having ZEN concentrations higher than the tolerance limit of 500 μg/kg. The survey on fungi contamination showed that all samples were contaminated by fungi(range: 5.0-1.4×105 CFU/g). There were 18 and 3 samples with quantities of fungi higher than the tolerance and forbidden limits, respectively. The Aspergillus, Penicillium, Fusarium, Trichoderma and Mucor genuses were the predominant fungi in corn feed ingredients, with detection rates of 71.3%(67), 60.6%(57), 71.3%(67), 27.7%(26), and 24.5%(23), respectively. The detection rate of Fusarium moniliforme, 73.4%(69/94)was higher than that of Aspergillus flavus, 41.5%(39/94). Conclusion: In this survey, the corn feed ingredients were not seriously contaminated by

    To examine the roles of child cognitions and parental feeding practices in explaining child intentions and behaviour regarding fruit and vegetable consumption. Cross-sectional surveys among pre-adolescent children and their parents. The child questionnaire included measures of fruit and vegetable consumption and cognitions regarding fruit and vegetable consumption as postulated by the Attitude-Social Influence-Self-Efficacy (ASE) model. The parent questionnaire included measures of parental feeding practices derived from the Comprehensive Feeding Practices Questionnaire (CFPQ). In total, 963 parents and 796 students in grades 5 and 6 from eighteen schools in the south-western part of Norway participated. A large portion of child intention to eat fruit and child fruit consumption was explained by child cognitions (29 % and 25 %, respectively). This also applied to child intention to eat vegetables and child vegetable consumption (42 % and 27 %, respectively). Parent-reported feeding practices added another 3 % to the variance explained for child intention to eat fruit and 4 % to the variance explained for child vegetable consumption. The results from the present study supported the application of the ASE model for explaining the variance in child intentions to eat fruit and vegetables and in child consumption of fruit and vegetables. Furthermore, our findings indicated that some parental feeding practices do have an influence on child intentions and behaviour regarding fruit and vegetable consumption. However, the role of parental feeding practices, and the pathways between feeding practices and child eating intentions and behaviour, needs to be further investigated.

    Full Text Available ABSTRACT  The purpose of this study was to evaluate various types of fermentor for dry matter digestibility (DMD, organic matter digestibility (OMD, and the chemical composition of fermented seaweed. Five types of seaweed were used as substrates included green strain of Kappaphycus alvarezii, brown strain of K. alvarezii, Gracilaria gigas, Sargassum sp., and Caulerpa sp. The treatments were four fermentors, namely Bacillus sp. 2 mL/100 g of seaweed flour; 1.5% of tape yeast as a source of Rhizopus sp.; 1.5% of baker’s yeast as a source of Saccharomyces sp.; a mix of Bacillus sp., tape yeast of Rhizopus sp. and baker’s yeast of Saccharomyces sp. with compositions of 1 mL+1 g+1 g/100 g of seaweed flour; and control treatment. The results showed an increase in the percentage of DMD (21.94–27.76% and OMD (8.35–11.66% of all seaweed fermented using fermentor compared to control (DMD of 17.65–20.36% and OMD of 4.36–5.98%. Moreover, the highest result was obtained by the fermentor mix (DMD of 24.86–27.76% and OMD of 10.02–11.66%. Similar result was also found in the chemical composition of fermented seaweed, there was increase in protein content of 9.23–15.93% and nitrogen free extract (NFE of 56.05–70.26% in each seaweed treated with fermentation using fermentors, compared to controls (protein of 8.82–11.54% and NFE of 52.26–65.72%. Furthermore, the highest value was shown by seaweed fermented with mixed fermentors (protein of 9.92–15.93% and NFE of 58.47–70.26%. Yet, the opposite result was present in the ash, crude fiber, and fat content of seaweed fermented using fermentors of which the lowest value was found in treatment of mixed fermentor. Keywords: fermentation, fermentor, seaweed, quality, feed ingredients  ABSTRAK  Tujuan penelitian ini adalah mengevaluasi berbagai jenis fermentor terhadap kecernaan bahan kering (KBK, kecernaan bahan organik (KBO, dan komposisi kimia rumput laut terfermentasi.

    Incorporation of a plant blend in the diet can affect growth parameters and metabolism in carnivorous fish. We studied for the first time the long-term (1 year) metabolic response of rainbow trout fed from first feeding with a plant-based diet totally devoid of marine ingredients. Hepatic enzymes were analyzed at enzymatic and molecular levels, at 3, 8 and 24 h after the last meal to study both the short-term effects of the last meal and long-term effects of the diet. The results were compared with those of fish fed a control diet of fish meal and fish oil. Growth, feed intake, feed efficiency and protein retention were lower in the group fed the plant-based diet. Glucokinase and pyruvate kinase activity were lower in the livers of trout fed the plant-based diet which the proportion of starch was lower than in the control diet. Glutamate dehydrogenase was induced by the plant-based diet, suggesting an imbalance of amino acids and a possible link with the lower protein retention observed. Gene expression of delta 6 desaturase was higher in fish fed the plant-based diet, probably linked to a high dietary level of linolenic acid and the absence of long-chain polyunsaturated fatty acids in vegetable oils. Hydroxymethylglutaryl-CoA synthase expression was also induced by plant-based diet because of the low rate of cholesterol in the diet. Changes in regulation mechanisms already identified through short-term nutritional experiments (<12 weeks) suggest that metabolic responses are implemented at short term and remain in the long term.

    To identify parental child-feeding strategies that may increase children's fruit or vegetable intake, since the relationship between these strategies and children's intake has never been investigated for fruit and vegetables as two separate food groups. A survey study, where parents provided information about their practices in relation to feeding their children and about their own and their children's fruit and vegetable intake. Children completed a preference questionnaire about fruit and vegetables. To find underlying parental child-feeding strategies, factor analysis was applied to parents' practices in relation to fruit and vegetables separately. Regression analysis was used to predict the effect of these strategies on children's fruit and vegetable intake. The impact of the strategies was further analysed by estimating children's intake based on the frequency of use of specific strategies. The study was conducted at three primary schools in The Netherlands. A total of 259 children between 4 and 12 years old and their parents (n 242). Parents used different strategies for fruit as compared with vegetables. The vegetable-eating context was more negative than the fruit-eating context. Parental intake and presenting the children with choice were positive predictors of children's intake of both fruit and vegetables. The intake difference based on frequency of use of the strategy 'Choice' was 40 g/d for vegetables and 72 g/d for fruit (P fruit- and vegetable-eating situations, since this is a powerful strategy to stimulate children's fruit and vegetable intake.

  2. Knowledge of Constituent Ingredients in Enteral Nutrition Formulas Can Make a Difference in Patient Response to Enteral Feeding.

    Science.gov (United States)

    Savino, Patricia

    2017-08-01

    Enteral feeding is considered the preferred method for providing a complete or supplemental source of nutrition to patients. Enteral formulas (EFs) are traditionally assessed from general information provided by the manufacturer such as caloric density, percentage of macronutrients, and micronutrients to meet the Recommended Dietary Allowance. Sometimes labeling information highlights particular ingredients to indicate specific properties at a metabolic or nutrition level. However, it is necessary to review the quality and composition of any enteral formula, since the basic components are responsible for tolerance and nutrition efficacy, and this should not be overshadowed by the benefit of a single constituent. Intolerance to EF is commonly attributed to individual patient response or to the means of administration. The objective of this review is to highlight the importance of appraising EFs with regard to composition and effect on the gastrointestinal tract.

The objective of this investigation is to study a set of vegetable and cereal proteins in terms of physicochemical and functional properties. Twenty protein sources were studied: five soya bean flour samples, one pea flour and fourteen newly developed blends of soya bean and maize germ (fi ve concentrates and nine hydrolysates. The physicochemical characterization included pH (5.63 to 7.57, electrical conductivity (1.32 to 4.32 mS/cm, protein content (20.78 to 94.24 % on dry mass basis, free amino nitrogen (0.54 to 2.87 mg/g and urease activity (0.08 to 2.20. The functional properties showed interesting differences among proteins: water absorption index ranged from 0.41 to 18.52, the highest being of soya and maize concentrates. Nitrogen and water solubility ranged from 10.14 to 74.89 % and from 20.42 to 95.65 %, respectively. Fat absorption and emulsification activity indices ranged from 2.59 to 4.72 and from 3936.6 to 52 399.2 m2/g respectively, the highest being of pea flour. Foam activity (66.7 to 475.0 % of the soya and maize hydrolysates was the best.

    The effect of certain simple and cost-effective processing methods on the nutritional and anti-nutritional properties of seed materials of an under-utilized food legume, Mucuna pruriens (L.) DC. var. utilis (Wall. ex Wight) Baker ex Burck (velvet bean, VB), collected from Valanadu, Kerala, India was analyzed in experiment 1. The raw VB seeds were found to contain appreciable levels of crude protein (263.2 g/kg dry matter (DM)); ether extract (79.6 g/kg DM); crude fiber (95.8 g/kg DM) and ash content (38.4 g/kg DM). Among the different treatments used, soaking in sodium bicarbonate solution + autoclaving was more effective in reducing maximum levels of various anti-nutritional compounds of VB seeds. Furthermore, in experiment 2, the effect of inclusion of different levels of velvet bean meal (VBM; subjected to soaking in sodium bicarbonate solution + autoclaving) as an alternative protein source in poultry feed on the growth performance of commercial-type broiler birds was investigated. The results indicate that the inclusion of VBM up to the 40% level exhibited better growth performance of the broiler birds such as feed intake, body weight gain, feed conversion ratio and protein efficiency ratio in both the starter and finisher phases.

  7. Fruit and vegetable by-products as novel ingredients to improve the nutritional quality of baked goods.

    Gómez, Manuel; Martinez, Mario M

    2017-03-31

    The industrial manufacturing of fruits and vegetables generates approximately 50% by-product waste, causing a negative environmental impact and significant expenses. Nevertheless, fruit and vegetable by-products (FVB) are rich nutrients and extranutritional compounds that contribute to bowel health, weight management, lower blood cholesterol levels and improved control of glycemic and insulin responses. Due to the positive influence of FVB fibers and bioactive compounds during the digestion of glycemic carbohydrates, such as starch, baked goods are ideal food systems to accommodate FVB, since most of them have a high glycemic index. Therefore, this is an area of recent interest with critical environmental, economic and health implications worldwide. However, the utilization of FVB in baked goods leads to the loss of acceptability, in many cases caused by a lack of understanding of the physical structure and composition of FVB and their effects on food quality. The objective of this review is to provide a mechanistic understanding of the impact of the physical structure and composition of FVB on common baked goods and their influence on the nutritional and physical quality of the resulting product. This review will support the use of FVB as ideal ingredients while improving the added value of waste streams.

    The present study aimed to explore the process in which parental food-related behaviors might influence preadolescent children's vegetable consumption, addressing potential mediating effects of child cognitions. Cross-sectional surveys were performed among 10-12-year-olds and their parents. The child questionnaire included measures of vegetable consumption and child cognitions related to vegetable consumption (i.e. attitudes, social influence, self-efficacy and intention). The parent questionnaire included measures of parental feeding practices adapted from the Comprehensive Feeding Practices Questionnaire. Stepwise regressions were performed to reveal potential mediating effects of child cognitions on the associations between parental feeding practices and child vegetable consumption. Our results suggested a mediating effect of child self-efficacy on the association between parental restrictive behavior and child vegetable consumption. Other potential mediating effects were not supported in this study. Copyright © 2013 Elsevier Ltd. All rights reserved.

    A strain of Kocuria rosea with keratinolytic capacity was cultured aerobically on submerged feathers to obtain a fermented feather meal (FFM). This FFM enriched with cells of K. rosea mainly contains crude protein (71%). The pepsin digestibility of the fermented product (88%) was similar to the value of the commercial feather meal and more than 70% greater that untreated feathers. The bacterial biomass improved the content of amino acids lysine (3.46%), histidine (0.94%) and methionine (0.69%). Additionally, the amino acid availability tested by in vivo assay was greater than commercial feather meal. The microbial cells also supplied carotenoid pigments to FFM (68 ppm). These results suggest that feather meal enriched with K. rosea may be useful in animal feeding as protein and pigment source.

    Full Text Available Chicken egg yolks generally owe their color to yellow carotenoids. The addition of synthetic red pigments allows changes in color, from the original yellow to red hues which may be more appealing to consumers in certain markets.Our aim has been to test whether ground crayfish shells, which are a rich and natural source of astaxanthin, produce detectable changes in the coloration of egg yolks through the accumulation of this carotenoid. Laying hens were fed with a commercial feed mixed with crayfish powder and the carotenoid profiles of the yolks in the eggs laid during the trial were monitored by HPLC. The analyses showed a progressive increase in the astaxanthin concentration in the egg yolks, reaching similar levels to those obtained for the rest of present carotenoid pigments.La yema de huevo de gallina debe su coloración a la presencia de carotenoides de tonalidad amarilla. La adición de colorantes sintéticos de tonalidades rojas permite modificar e incrementar la coloración de la yema desde el amarillo original a tonos rojos que pueden ser demandados en ciertos mercados según las preferencias del consumidor. El objetivo del trabajo fue probar si un triturado obtenido a partir de caparazones de cangrejo, que es una fuente natural y rica en astaxanteno, produce cambios detectables en la coloración de la yema de huevo por la acumulación de dicho carotenoide. Las gallinas ponedoras se alimentaron con un pienso comercial al que se adicionó triturado de caparazón de cangrejo. Se realizó un seguimiento de los cambios en la composición carotenoide (mediante HPLC de la yema de los huevos puestos durante el periodo de alimentación suplementada. Los análisis mostraron una progresiva incorporación de astaxanteno que alcanzó niveles similares al resto de carotenoides presentes inicialmente en la yema.

    Full Text Available ABSTRACT The high composition of import raw material of fish diet in Indonesia causes feed price expensively and should be replaced using local materials such as green macro algae. It is, therefore, this study aimed to evaluate effect of diet containing the Caulerpa lentillifera, as feed ingredient in the diet of Nile tilapia Oreochromis niloticus. This study consisted of two experiments which were C. lentillifera digestibility test for raw material feed for tilapia and growth performance test of tilapia. C. lentillifera digestibility test was done by using Cr2O3 as indicators and analysis of faecal tilapia. The second experiment is growth performance test using a completely randomised design with four diets were formulated at variuos rates of C. lentillifera meal of 0 (control, 10, 20, and 30%. A number of 240 tilapia fingerlings of 3.41±0.10 g in mean weight were randomly stocked in 12 aquaria and fed on diet test for growth performanced of rearing period. C. lentillifera digestiility test result showed a good value as a raw material feed tilapia, the digestibility of C. lentiliifera and protein digestibility amounted to 68.81% and 86.31%. Growth performance parameters showed the use of 10% and 20% is not significantly different from the control (P>0.05, to the final body weight, protein efficiency ratio, protein retention, specific growth rate, and feed efficiency. But, the diet test at 30% performed the lowest growth performance and feed utilization as well of tilapia fingerlings. This study, therefore, concludes that C. lentillifera meal could be used up to 20% in the tilapia diet. Keywords: Caulerpa lentillifera, Nile tilapia, feed utilization, growth performance  ABSTRAK Tingginya jumlah bahan baku impor dalam pakan ikan di Indonesia menyebabkan harga pakan yang tinggi dan harus diganti menggunakan bahan alternatif lokal seperti makro alga.

    2008-08-01

    Every clinician is asked "What should I feed my pet?" Understanding the ingredients in pet food is an important part of making the best recommendation. Pet food can be as simple as one ingredient or as complicated as containing more than 60 ingredients. Pet food and its ingredients are regulated by the Food and Drug Administration and state feed officials. Part of that regulation is the review and definition of ingredients. Existing ingredients change and new ingredients become available so the need for ingredient definitions grows. Ingredients for product formulations are chosen based on their nutrient content, digestibility, palatability, functionality, availability, and cost. As an example, a typical, nutritionally complete dry dog food with 42 ingredients is examined and the ingredients are discussed here. Safe, healthy pet food starts with safe ingredients sourced from well-monitored suppliers. The ultimate goal of both veterinarians and pet food manufacturers is the same--long healthy lives for dogs and cats.

    2011-12-01

    Despite substantial evidence suggesting that a diet high in fruit and vegetables (FV) is associated with reduced risk of cancer, only 21% of children in the UK consume the recommended 5 portions of fruit or vegetables a day. This review examines the role of parenting style, feeding style and feeding practices in FV consumption in early childhood. Whilst inconsistencies in concepts and terminology cloud this literature, overall the evidence suggests that the context of an authoritative parenting and feeding style is associated with better FV consumption in the childhood years. This context is typified by emotional warmth but high expectations for children's dietary adequacy and behaviour, accompanied by specific feeding practices such as modeling consumption of FV, making FV available within the home, covertly restricting unhealthy alternative snack foods, and encouraging children to try FV. Further longitudinal and intervention studies are required to determine the efficacy of modification of parenting style and feeding practice on children's FV intake. Copyright © 2011 Elsevier Ltd.

    The inhibitory effect of enterocin AS-48 against Staphylococcus aureus was investigated in various types of bakery ingredients. Antibacterial activity greatly depended on the food substrate, ranging from complete inactivation of S. aureus in liquid caramel (in which the bacterium survived poorly) to no significant inhibition (as in vanilla or chocolate creams). Significant reductions of viable counts in the range of 1.8 to 2.7 log units (P chocolate substrates, enterocin AS-48 was tested in combination with other antimicrobials. Bactericidal activity increased markedly for the combinations of AS-48 and 0.1% eugenol (v/v), 0.5% 2-nitropropanol (v/v), or 3% Nisaplin (w/v). Enterocin AS-48 could be applied in combination with other antimicrobials for preservation of bakery ingredients against S. aureus.

    Fruit and vegetable intake in children remains below recommendations in many countries. The long-term effects of early parental feeding practices on fruit and vegetable intake are not clearly established. The purpose of the current study was to examine whether early feeding practices influence later fruit and vegetable intake in preschool children. The study used data from 4 European cohorts: the British Avon Longitudinal Study of Parents and Children (ALSPAC), the French Etude des Déterminants pre et postnatals de la santé et du développement de l'Enfant study, the Portuguese Generation XXI Birth Cohort, and the Greek EuroPrevall study. Fruit and vegetable intake was assessed in each cohort by food-frequency questionnaire. Associations between early feeding practices, such as breastfeeding and timing of complementary feeding, and fruit and/or vegetable intake in 2-4-y-old children were tested by using logistic regressions, separately in each cohort, after adjustment for infant's age and sex and maternal age, educational level, smoking during pregnancy, and maternal fruit and vegetable intake. Large differences in early feeding practices were highlighted across the 4 European cohorts with longer breastfeeding duration in the Generation XXI Birth Cohort and earlier introduction to complementary foods in ALSPAC. Longer breastfeeding duration was consistently related to higher fruit and vegetable intake in young children, whereas the associations with age of introduction to fruit and vegetable intake were weaker and less consistent across the cohorts. Mothers' fruit and vegetable intake (available in 3 of the cohorts) did not substantially attenuate the relation with breastfeeding duration. The concordant positive association between breastfeeding duration and fruit and vegetable intake in different cultural contexts favors an independent specific effect.

    The objective of this research was to investigate the effects of ingredients and preparation methods on the sensory and nutritional properties of pureed turkey and carrots. Turkey samples varying in added liquid and muscle composition were developed. Seasoning application methods were also studied. Pureed carrots were formulated with no added thickener, added modified corn starch, rice cereal, or skim milk powder. Small changes in added liquid and seasoning application altered the perceived texture of the turkey. Pureed carrots with added modified corn starch were more slippery and firm than other samples. The addition of skim milk powder or rice cereal did not alter sensory properties but led to higher protein contents when compared to unthickened carrots. In-house formulations did not differ in sensory ratings of appearance and flavor when compared to commercial products but contained more carbohydrates. Modest changes in recipes for pureed products can improve sensory appeal and nutrient density; quality in-house products are feasible with only minor alterations.

    To examine the association between feeding practices and both fruit and vegetable intakes of preschoolers. Cross-sectional; data collected from 2009 to 2010. Child care centers enrolled in the cohort of the Synergistic Theory and Research on Obesity and Nutrition Group Kids program. Three hundred and sixteen mother-child dyads were recruited in the baseline survey as primary caregivers of children aged 2-5 years. Ten aspects of maternal feeding practices were measured using a Comprehensive Feeding Practices Questionnaire. The frequency of children's fruit and vegetable consumption was estimated by mothers. Spearman's rank order correlation and linear regression analysis between parental feeding practices and both fruit and vegetable consumption were adjusted for potential confounders. Pearson's correlation coefficients among 10 parental feeding practices were calculated. Children in the study consumed fruit 1.7 ± 0.9 times per day and vegetables 1.4 ± 0.8 times per day. Feeding practices of building a healthy home food environment and involvement were positively related and those of restriction for health were negatively related to children's vegetable consumption (P < .001); moreover, encouraging balance and variety and monitoring were positively related to children's fruit consumption (P < .001). The results of this study suggest that both fruit and vegetable intakes of preschool children are more likely to increase if parents employ feeding practices that encourage child autonomy, competence, and relatedness.

    This study examined the potential of producing a protein-rich fungus, Rhizopus microsporus (var. oligosporus), as an aquaculture feed ingredient on vinasse generated during sugar-based ethanol fermentation. Optimization studies showed prolific fungal growth at pH 5.0 and 30 degrees C on vinasse with nutrient (nitrogen and phosphorus) supplementation. The molasses-vinasse resulted in the highest specific fungal biomass yield of 0.21 (g biomass increase/(g initial biomassxg soluble chemical oxygen demand (SCOD) removed)). Organic and inorganic matters were significantly reduced, e.g., 42.02% SCOD and 24.41% total dissolved solids. Thus, the treated effluent could be recycled as process water or used for land applications. The fungal biomass was found to have 45.55% crude protein with significantly high amino acids, arginine and threonine. The integration of innovative fungal technology with sugar-based ethanol production could provide an opportunity for producing food-grade fungal protein for animal feed application with simultaneous water reclamation. 2010 Elsevier Ltd.

    The purpose of this study was to investigate the role of parent and child characteristics in explaining children's fruit and vegetable intakes. In 2008, parents of preschoolers (mean age 3.5 years) from 56 schools in Belgium-Flanders completed questionnaires including a parent and child fruit and vegetable food frequency questionnaire, general parenting styles (laxness, overreactivity and positive interactions), specific food parenting practices (child-centered and parent-centered feeding practices) and children's characteristics (children's shyness, emotionality, stubbornness, activity, sociability, and negative reactions to food). Multiple linear regression analyses (n = 755) indicated a significant positive association between children's fruit and vegetable intake and parent's intake and a negative association with children's negative reactions to food. No general parenting style dimension or child personality characteristic explained differences in children's fruit and vegetable intakes. Child-centered feeding practices were positively related to children's fruit and vegetable intakes, while parent-centered feeding practices were negatively related to children's vegetable intakes. In order to try to increase children's fruit and vegetable consumption, parents should be guided to improve their own diet and to use child-centered parenting practices and strategies known to decrease negative reactions to food.

    A 20-d zebrafish (Danio rerio) feeding trial, in which a near doubling of fish weight was achieved, was conducted with GM feed ingredients to evaluate feed intake, growth, stress response and uptake of dietary DNA. A partial aim of the study was to assess zebrafish as a model organism in GM safety assessments. Roundup Ready soya (RRS), YieldGard Bt maize (MON810) and their non-modified, maternal, near-isogenic lines were used in a 2 x 2 factorial design. Soya variety and maize variety were the main factors, both with two levels; non-GM and GM. Compared with fish fed non-GM maize, those fed GM maize exhibited significantly better growth, had lower mRNA transcription levels of superoxide dismutase (SOD)-1 and a tendency (non-significant) towards lower transcription of heat shock protein 70 in liver. Sex of the fish and soya variety had significant interaction effects on total RNA yield from the whole liver and transcription of SOD-1, suggesting that some diet component affecting males and females differently was present in different levels in the GM and the non-GM soya used in the present study. Dietary DNA sequences were detected in all of the organs analysed, but not all of the samples. Soya and maize rubisco (non-transgenic, multicopy genes) were most frequently detected, while MON810 transgenic DNA fragments were detected in some samples and RRS fragments were not detected. In conclusion, zebrafish shows promise as a model for this application.

    2011-08-01

    This study aimed to explore the prospective relationship between maternal feeding practices and young children's frequency of consumption of fruits, vegetables and sweets, and also child weight-for-height z-scores. Participants were 60 mothers who completed questionnaires when their children were 1 year old and again when their children were 2 years old. Regression analyses were performed. After controlling for availability and prior child consumption of the target food, maternal use of pressure to eat at 1 year predicted lower child frequency of fruit consumption at 2 years and approached significance for lower vegetable consumption. Maternal modelling of healthy eating at 1 year predicted higher child frequency of vegetable consumption at 2 years. Restriction did not significantly predict child frequency of consumption of fruits, vegetables or sweets over time. Child weight-for-height scores at 2 years were predicted by weight-for-height at 1 year but not by feeding practices. The findings suggest that maternal feeding practices can influence child eating at a very young age. Interventions should focus on encouraging parents to model healthy eating to promote healthy eating in children. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Estuarine marine-dependent species, such as Rhabdosargus holubi, depend greatly on structured sheltered environments and important feeding areas provided by estuaries. In this study, we investigate the ecological feeding niches of the estuarine marine-dependent sparid, R. holubi, by using conventional stomach contents and stable isotope methods (δ13C and δ15N signatures). The study has been carried out in five temperate estuaries in order to understand how fish feed in multiple intertidal vegetated habitats. These habitats included the submerged seagrass, Zostera capensis, and both previously unexplored small intertidal cord grass, Spartina maritima, and the common reed, Phragmites australis. The diet varied amongst habitats, estuaries and fish sizes and data consistently confirmed their omnivorous diet relating to ontogenetic niche shifts. Stomach contents revealed the importance of benthic prey within both the S. maritima and P. australis habitats in the absence of large intertidal vegetation, available during low tides. Similarly, isotopic mixing models showed that R. holubi from these habitats have a greater isotopic niche compared to the Z. capensis habitat, due to their limited availability during the falling tide, suggesting migration between available habitats. Stable isotopes confirmed that R. holubi actively feeds on the epiphytic algae (especially diatoms) covering the leaves and stalks of plant matter, as supported by Bayesian mixing models. These findings add to the current knowledge regarding habitat partitioning in multiple aquatic vegetation types critical to fish ecology and the effective management and conservation of estuaries.

    Full Text Available In the culture of tilapia limited supply and high cost of fish meal have forced nutritionists to consider alternative sources of protein. Due to the importance of the products and by-products in fish feed, this paper aims to show the alternatives that have been used to partially or totally replace fish meal and soybean meal in tilapia growing. This paper showsthe maximum or optimal use of vegetable by-products for tilapia as cottonseed meal, sunflower, canola, soybean and Leucaena. It also deals with the inclusion with agro-industrial by-product such as corn, sorghum, coffee pulp, cocoa, wheat and citrus. The present study also deals with the use of aquatic plants such as Lemna and Azolla, single-celled plant protein source as antibiotics and probiotics. Finally, this paper also refers to animal by-products as silage, manure and earthworm usage. There is a high potential for using plant, livestock and agro-industrial by-products in fresh and processed food for the tilapia, but depending on the product, pretreatment to improve its balance of nutrients or eliminate anti-nutritional factors may be required.

    Full Text Available The overall impacts of winter feeding, including the effects of both forage and reindeer (Rangifer tarandus, were studied in an experiment in the Hammastunturi herding cooperative (68°N, Finland, with 300 reindeer in a sub-xeric heath forest (35 ha during March/April 2009 and 2010. The feeding practices on the 50 plots were: (1 feeding with grass silage+hay with leftovers cleared in the spring; (2 feeding with grass silage+hay with leftovers not cleared; and (3 feeding with pellets. In addition, (4 unfenced and (5 fenced control plots were included, on which the reindeer were not fed. No invasive plant species introduced through grass silage+hay were observed on the plots. The coverage of Deschampsia flexuosa increased on grass silage+hay plots after the first winter, and both coverage and height of the grass increased after the second winter. The coverage of Dicranum sp. and Pleurozium schreberi was lower on plots where reindeer were fed with grass silage (leftover silage not cleared vs. controls. Some dwarf shrubs, e.g., Calluna vulgaris, showed a similar response after the second winter. The N content of Empetrum nigrum was higher on grass silage plots (leftover silage not cleared after the first winter vs. controls. After two winters, the N content of both E. nigrum and Vaccinium myrtillus was increased. Of the soil variables studied, C/N decreased on grass silage+hay plots vs. fenced controls. We conclude that even a moderate level of feeding may cause changes that can lead to a gradual shift from nutrient-poor heath forest towards a more nutrient-rich type.

    To examine the moderating effects of feeding styles on the relationship between food parenting practices and fruit and vegetable (F & V) intake in low-income families with preschool-aged children. Focus group meetings with Head Start parents were conducted by using the nominal group technique. Parents completed information on food parenting practices and feeding styles. Three dietary recalls were collected on each child. Parents completed measures in Head Start centers and/or over the telephone. 667 parents of preschool-aged children participated. Food parenting practices and F & V intake. Mean differences in the food parenting practices across the 4 feeding styles were established through multivariate general linear modeling using MANOVA. Moderated multiple regression analysis was conducted to examine the moderating role of feeding style on food parenting practices and child F & V intake. The indulgent feeding style moderated the relationship between food parenting practices and child F & V intake. This study indicates that parents' feeding styles have a moderating effect on the relationship between the food parenting practices and children's F & V intake. This finding can facilitate the development of interventions aimed at reducing childhood overweight. Copyright © 2013 Society for Nutrition Education and Behavior. Published by Elsevier Inc.

    The ban of processed animal proteins (PAPs) in feed for farmed animals introduced in 2001 was one of the main EU measures to control the bovine spongiform encephalopathy (BSE) crisis. Currently, microscopy and polymerase chain reaction (PCR), are the official methods for the detection of illegal PAPs in feed. However, the progressive release of the feed ban, recently with the legalization of non-ruminant PAPs for the use in aquaculture, requires the development of alternative methods to determine the species origin and the source (legal or not). Additionally, discussions about the need for quantitative tests came up, particularly if the zero-tolerance-concept is replaced by introducing PAP thresholds. To address this issue, we developed and partially validated a multiplex mass spectrometry-based immunoassay to quantify ruminant specific peptides in vegetal cattle feed. The workflow comprises a new sample preparation procedure based on a tryptic digestion of PAPs in suspension, a subsequent immunoaffinity enrichment of the released peptides and a LC-MS/MS based analysis for peptide quantification using isotope labelled standard peptides. For the very first time, a mass spectrometry-based method is capable of detecting and quantifying illegal PAPs in animal feed over a concentration range of four orders of magnitude with a detection limit in the range of 0.1 % to 1 % (w/w).

    A growing body of evidence from Western countries shows that infant feeding practices are associated with later childhood dietary habits, but little is known about these relationships in non-Western countries with different food cultures. We examined the association of breast-feeding duration and age at introduction of solid foods with later intake of fruit and vegetables among Japanese toddlers. Information on breast-feeding duration, age at introduction of solid foods and child's intake frequency of fruit and vegetables were collected with a self-administered questionnaire at 16-24 months postpartum. Logistic regression analysis was used to calculate odds ratios of low intake (vegetables for each infant feeding practice. Japan. Japanese mother-child pairs (n 763) from a prospective birth cohort study. Neither breast-feeding duration nor age at introduction of solid foods was associated with fruit intake at 16-24 months of age. Breast-feeding duration, but not age at introduction of solid foods, was associated with later intake of vegetables. When breast-feeding duration was categorized into two groups with the cut-off at 6 months, children who were breast-fed for ≥6 months had a significantly decreased risk of low intake of vegetables (OR=0·53; 95% CI 0·34, 0·84) than those breast-fed for vegetable intake (OR=0·59; 95% CI 0·36, 0·97). This finding suggests that ≥6 months of breast-feeding may prevent low intake of vegetables in early childhood among Japanese toddlers.

    The invasive brown marmorated stink bug,Halyomorpha halys(Stål) (Heteroptera: Penatomidae), is a major pest of agricultural crops in the Mid-Atlantic States. Here we report the seasonal abundance, host preference, and injury potential ofH. halyson tomato, bell pepper, green bean, sweet corn, eggplant, and okra in a small-scale, diversified vegetable farm setting. Life-stage densities, feeding injury, and crop phenology were monitored throughout the growing season in each crop. Populations consisted of both overwintered adults and F1 progeny and encompassed almost two generations over the growing season.H. halyspreferred host plants with reproductive structures for feeding and was more abundant and capable to reproduce on vegetable crops that had extended periods of fruiting. Sweet corn, okra, and bell pepper had significant higher abundances of adults and nymphs compared with green bean, eggplant, and tomato. Results showed significant differences in the reproductive suitability of the host plants, as evident by the relative proportion of nymphal stages to adults. Eggplant, okra, and bell pepper were the most suitable host plants for reproduction and development, as evident by higher proportions of nymphs, with abundance trends indicating progressive development to adult eclosion. Crop loss potential due toH. halysfeeding injury varied significantly among vegetable host plants. Sweet corn, okra, bell pepper, and tomato were very susceptible and experienced the highest injury rate per stink bug. The implications of these findings with respect to sampling and management ofH. halysin vegetable production are discussed. © The Authors 2016.

    A method of multiplex polymerase chain reaction (PCR) followed by the hybridization on a hydrogel oligonucleotide biochip was developed for simultaneous identification of ten different transgenic elements of plant DNA in feed and food products. The biochip contained 22 immobilized probes intended for (i) detection of plant DNA; (ii) plant species determination (soybean, maize, potato, rice); (iii) identification of transgenic elements, including 35S CaMV, 35S FMV, rice actine gene promoters, nos, 35S CaMV, ocs, pea rbcS1 gene terminators, and bar, gus, nptII marker genes. The limit of detection was 0.5% of genetically modified (GM) soybean and maize in analyzed samples. Identification of transgenic DNA in food and feed products using either the developed approach or real-time PCR led to virtually identical results. The assay can be used for selection of GM samples by screening food and feed products for subsequent quantitative determination of the GM component based on the identified transgene.

  17. Spring fen Scheuchzerio-Caricetea nigrae in the Polish Western Carpathians – vegetation diversity in relation to soil and feeding waters

    Directory of Open Access Journals (Sweden)

    Anna Koczur

    2013-05-01

    Full Text Available The species composition of vegetation associated with the Carpathian fens primarily depends on the type of water present and the hydrological feeding of the soils that occur there. These, in turn, shape the fertility of the fens. Those with typically formed Carici-Agrostietum caninae and Valeriano-Caricetum flavae fundamentally differ in the properties of their soils and feeding waters. These include differences in mineral content, pH, CaCO3 levels, degree of peat decomposition, electrical conductivity and oxygenation of the waters that feed the fens. Carici-Agrostietum caninae is a homogenous plant association adapted to extreme habitat conditions. It is characterized by a very narrow range of essential soil and feeding water parameters. Valeriano-Caricetum flavae is a highly diverse association. Considerable diversity both in terms of plant species and vegetation structure reflects very wide ranges in the properties of soil and feeding water. Vegetation patches of transitory character were also identified. These contained plant species characteristic of both associations. The character of the vegetation depends mainly on fen soil pH and the degree of mineralization of the feeding waters. It is only these parameters that allow intermediate patches to be clearly distinguished. The degree of peat decomposition, mineral content and water oxygenation all differ for Carici-Agrostietum caninae and Valeriano-Caricetum flavae, whereas the values for intermediate patches display a range of parameters typical of both investigated associations. Consequently, vegetation present in these patches reflects to a greater or lesser extent one of the two analyzed plant associations.

    Full Text Available Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC of dry matter (ADCDM, crude protein (ADCCP, gross energy (ADCGE and amino acids (ADCAA of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g. The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT, using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg-1 crude protein and 3,692 Kcal kg-1 gross energy. Additionally 1.0 g kg-1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%, followed by the other ingredients. There was no significant difference between the soybean meal (95.16%, fish meal (92.97% and the corn meal (91.90% for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%. The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients.

    This experiment was evaluation of the effects of increasing concentrations of crude glycerin from waste vegetable oil (CGWVO) in diets on feed intake, digestibility, ruminal fermentation characteristics, and nitrogen balance of goats. Four crossbred male (Thai Native × Anglo Nubian) goats, with an average initial body weight (BW) of 31.5 ± 1.90 kg, were randomly assigned according to a 4 × 4 Latin square design. The dietary treatments contained 0, 2, 4, and 6 % of dietary dry matter (DM) of CGWVO. Based on this experiment, there were significantly different (P > 0.05) among treatment groups regarding DM intake and digestion coefficients of nutrients (DM, OM, CP, EE, NDF, and ADF), which goats receiving 6 % of CGWVO had lower daily DMI and nutrient intake than those fed on 0, 2, and 4 % of CGWVO. Ruminal pH, NH3-N, and blood urea nitrogen (BUN) concentration were unchanged by dietary treatments, except that for 6 % of CGWVO supplementation, NH3-N, and BUN were lower (P < 0.05) than for the diets 0 % of CGWVO, while the differences between the diets 0, 2, and 4 % of CGWVO were not significant. The amounts of N absorption and retention were similar among treatments, except that for 6 % of CGWVO which N absorption was lower (P < 0.05) than among treatments while the difference between the diets 0, 2, and 4 % of CGWVO were not significant. Based on this study, CGWVO levels up to 4 % in total mixed ration could be efficiently utilized for goats. This study was a good approach in exploiting the use of biodiesel production from waste vegetable oil for goat production.

    Full Text Available This study consisted of two experiments, conducted to assess the impact of phase at which vegetable protein (VP diets are introduced to broiler chicks, and preference of birds for diets based on soybean or canola meal (CM. Two hundred and ten day-old Cobb 500 chicks were randomly distributed into five dietary groups in the main experiment. One group was fed on animal protein (AP diet all through to 21 days of age; two other groups were started on AP diet for 7 days and then switched to diets containing soybean meal (AP-SBM or AP-CM, while two other diets (SBM-AP and CM-AP were started on one of the VP diets for 7 days and then switched to AP diet. A sub-experiment on thirty birds raised on a commercial diet to 7 days was used in a feed selection test to quantify the preference of birds for the diets containing mainly CM or SBM. Chicks were reared under similar care and management conditions and the diets were iso-caloric and iso-nitrogenous. Results of the main experiment showed that chicks on CM-AP diet ate more (p<0.05 than those on the other diets up to day 7. Body weight gain was highest (p<0.001 on the AP-SBM diet while birds on the CM-AP diet weighed the least at 7 d. Feed intake, body weight gain, feed conversion ratio, mortality, bone growth, visceral organ development, and activities of digestive enzymes were similar between the groups from hatch to 21 days of age. Results of the second sub-experiment showed that chicks preferred the CM-based diets to the SBM-based diets at 8 to 14 d (p<0.001 and 15 to 21 d (p<0.01 when given a choice. Overall, the birds were not affected by the nature of the starter diet although they tended to prefer the canola to soybean diets.

    Children's vegetable consumption is below the public health recommendations. This study aimed to compare learning mechanisms to increase vegetable acceptance in infants at complementary feeding, namely repeated exposure (RE), flavor-flavor learning (FFL), and flavor-nutrient learning (FNL); measure the stability of the learning effect; and examine the impact of infants' feeding history on vegetable acceptance. The study was composed of a preexposure test, an exposure period, a postexposure test, and tests at 2-wk, 3-mo, and 6-mo follow-ups. At pre- and postexposure, a basic artichoke purée and carrot purée were presented to 95 French infants (6.4 ± 0.8 mo). During the exposure period, infants were randomly split into 3 groups and were exposed 10 times to the basic (RE group; 2 kJ/g; n = 32), a sweet (FFL group; 2 kJ/g; n = 32), or an energy-dense (FNL group; 6 kJ/g; n = 31) artichoke purée 2 or 3 times/wk. To evaluate acceptance, intake (g) and liking were recorded at home by parents. Between pre- and postexposure, intake of the basic artichoke purée significantly increased in the RE (+63%) and FFL (+39%) groups but not in the FNL group; liking increased only in the RE group (+21%). After exposure, artichoke was as much consumed and as much liked as carrot only in the RE group. Learning of artichoke acceptance was stable up to 3 mo postexposure. Initial artichoke intake was significantly related to the number of vegetables offered before the study started. RE is as effective as and simpler to implement than FFL and more effective than FNL for increasing vegetable acceptance at complementary feeding.

    Full Text Available Abstract Background The impact of salmonella contaminated feed ingredients on the risk for spreading salmonella to pigs was assessed in response to two incidences when salmonella was spread by feed from two feed mills to 78 swine producing herds. Methods The assessment was based on results from the salmonella surveillance of feed ingredients before introduction to feed mills and from HACCP - based surveillance of the feed mills. Results from the mills of the Company (A that produced the salmonella contaminated feed, were by the Chi. Square test compared to the results from all the other (B - E feed producers registered in Sweden. Isolated serovars were compared to serovars from human cases of salmonellosis. Results Salmonella (28 serovars was frequently isolated from imported consignments of soybean meal (14.6% and rape seed meal (10.0%. Company A largely imported soybean meal from crushing plants with a history of unknown or frequent salmonella contamination. The risk for consignments of vegetable proteins to be salmonella contaminated was 2.4 times (P Conclusions Salmonella contaminated feed ingredients are an important source for introducing salmonella into the feed and food chain. Effective HACCP-based control and associated corrective actions are required to prevent salmonella contamination of feed. Efforts should be taken to prevent salmonella contamination already at the crushing plants. This is challenge for the EU - feed industry due to the fact that 98% of the use of soybean/meal, an essential feed ingredient, is imported from crushing plants of third countries usually with an unknown salmonella status.

    2015-01-01

    Full Text Available On the basis of studying nutrition African ostriches for different ages in zoos, nurseries and small farms evaluated the nutritional value and balance of each of the components of plant feed, providing the needs for normal growth of poultry, development and productivity, to increase body weight, to increase egg production, quality hatching eggs, meat quality, output and quality of the young. Currently, in most cases, bird feed by copying the natural food, but it is the species, age and seasonal specifics, ensure that in the conditions of the zoo, nursery and farm problematic. Therefore, to solve this problem, we proposed the formulation of plant feed for feeding African ostriches in a zoo, nurseries and small farms that promote bird health, increase the rate of feeding, increase egg production, increase their survival, as well as the possibility of replacing expensive raw mat erials at cheaper developed using the optimization program "Food Optima Expert". To sustain ostriches exchange energy feed should be not less than 260 kcal / 100 g, protein content not less than 16 %. The complex research to develop formulations of plant feed for African ostriches in a zoo, nurseries and small farms and the quality of their analysis may be of interest in the full feeding African ostriches. The proposed formulation can extend its range of multi-component feed with a sufficiently high biological, energy value, the balanced composition of essential amino acids, vitamins and minerals adapted for ostriches, as well as the possibility of replacing expensive raw materials at lower cost.

    Rodríguez, C A; González, J

    2006-08-01

    An in situ study was conducted on four rumen-cannulated wethers to determine (using (15)N infusion techniques) the microbial contamination (mg bacterial DM or crude protein (CP)/100 mg DM or CP) and the associated error on the effective degradability of fourteen feeds: barley and maize grains, soyabean and sunflower meals, full-fat soyabean, maize gluten feed, soyabean hulls, brewers dried grains, sugarbeet pulp, wheat bran, lucerne and vetch-oat hays, and barley and lentil straws. The DM or CP contamination in residues (M) fitted to single exponential or sigmoid curves. A general model (M=m (1-e(-ft) ) (j)) was proposed to match this fit. Asymptotic values (m) varied from 2.84% to 13.3% and from 2.85% to 80.9% for DM and CP, respectively. Uncorrected results underestimated the effective degradability of both DM (Pcontent of the feed. The error in the effective degradability of CP was also negatively related to the CP content and its apparent effective degradability (R(2) 0.867). This equation allows easier and more accurate estimates of effective degradability, needed to improve protein-rationing systems.

    2010-01-01

    Background The impact of salmonella contaminated feed ingredients on the risk for spreading salmonella to pigs was assessed in response to two incidences when salmonella was spread by feed from two feed mills to 78 swine producing herds. Methods The assessment was based on results from the salmonella surveillance of feed ingredients before introduction to feed mills and from HACCP - based surveillance of the feed mills. Results from the mills of the Company (A) that produced the salmonella contaminated feed, were by the Chi. Square test compared to the results from all the other (B - E) feed producers registered in Sweden. Isolated serovars were compared to serovars from human cases of salmonellosis. Results Salmonella (28 serovars) was frequently isolated from imported consignments of soybean meal (14.6%) and rape seed meal (10.0%). Company A largely imported soybean meal from crushing plants with a history of unknown or frequent salmonella contamination. The risk for consignments of vegetable proteins to be salmonella contaminated was 2.4 times (P salmonella contamination. Also the level of feed mill contamination of salmonella was higher for feed mills belonging to Company A in comparison to the other companies before and also after heat treatment. Four (10.5%) of the 38 serovars isolated from feed ingredients (28) and feed mills (10) were on the EU 2007 top ten list of human cases of salmonellosis and all but eight (78.9%) on a 12 year list (1997-2008) of cases of human salmonellosis in Sweden. Conclusions Salmonella contaminated feed ingredients are an important source for introducing salmonella into the feed and food chain. Effective HACCP-based control and associated corrective actions are required to prevent salmonella contamination of feed. Efforts should be taken to prevent salmonella contamination already at the crushing plants. This is challenge for the EU - feed industry due to the fact that 98% of the use of soybean/meal, an essential feed ingredient

    The need for a reliable method for the detection of the amount of fuel in engine oils is nearly as old as the first engine oil specification. An increased amount of conventional fuel in the engine oil can cause several problems up to a mechanical breakdown of the engine. Modern fuels and new concepts in the base oil technology of modern engine oils up to so called 'bio engine oils' are responsible for the intensification of the discussion about of the acceptable amount of fuel in the engine oil. Especially in Germany there is an increasing volume of vegetable oil in the market which is used as an alternative fuel for conventional diesel fuel. Actually we have the first engine manufacturers who offer engines for the use with rape oil as a fuel. Unfortunately, up to now, we don't have a proved European - or DIN standard (only the prestandard DIN V 51605) for vegetable oils as fuel. The DIN prestandard is only for rape oil. But in the field palm-oil, sunflower-oil and several more can be found in the tanks of the engines. Moreover, up to know no official information exists about the allowed amount of vegetable oil in the engine oil. Even of those manufacturers who now offer the engines for the use with rape oil. The main answer of some engine manufacturers sounds like 'We don't allow the use of vegetable oil so there is no need for a limit value'. That is logical - at the first moment. But it is well known that a lot of trucks and power units are fired with vegetable oil. Till today WEARCHECK analysed several thousand used engine oils which where used in diesel engines with vegetable oil as fuel. The presentation gives some examples of rape oil fuel dilution and the influence on the engine and engine oil. Moreover it will give an idea how to determine the vegetable oil in engine oils. At the end the presentation shall initiate a discussion about a recommendation for the max. amount of vegetable oil dilution in engine oils. (orig.)

    Significant induction of mixed-function-oxidase (MFO) activity was observed in the small intestines of rats within 4-6 hr of ingestion of a single meal containing a Brassica vegetable (cabbage). Intact Brussels sprouts and a fractionated methanol-water extract of Brussels sprouts induced similar degrees of MFO activity in the livers, and small and large intestines of rats. However, the residue left after extraction of the polar compounds did not induce MFO activity. Different amounts of the various naturally-occurring thioglycosides and glucosinolates were found in the intact Brussels sprouts and in the extract, but virtually none were found in the extracted residue. When glucusinolates that were found in Brussels sprouts (sinigrin, progoitrin, glucobrassicin and glucotropaeolin) were fed separately to rats, only the indole glucosinolate, glucobrassicin, induced MFO activity (causing induction in the small intestines of the rats). This is consistent with the inducing activity of the various hydrolysis products of this glucosinolate. This is the first study in which an attempt has been made to define the inducing compounds in Brassica vegetables by feeding the individual purified glucosinolates.

    The use of probiotic bacteria to control bacterial infection in farmed fish is of clear practical interest. The aims of this study were to isolate and select a probiotic Bacillus sp. and to evaluate the effects of its supplementation on the growth and disease resistance of hybrid catfish. Bacillus siamensis strain B44v, selectively isolated from Thai pickled vegetables (Phak-dong), displayed a high potential as a probiotic in catfish culture. This bacterium produced a bacteriocin-like substance and exhibited a broad-spectrum antibacterial activity inhibiting both Gram-positive and Gram-negative bacteria, especially the fish pathogens Aeromonas hydrophila and Streptococcus agalactiae. The susceptibility to all 14 antibiotics tested implies its less possibility to be the antibiotic-resistant bacterium. Bacillus siamensis strain B44v possessed interesting adhesion properties, as shown by its high percentages of hydrophobicity (64.8%), auto-agglutination (73.8%), co-aggregation (67.2% with A. hydrophila FW52 and 63.5% with S. agalactiae F3S), and mucin binding (88.7%). The strain B44v survived simulated gastrointestinal conditions and produced protease and cellulase enzymes. Hybrid catfish (C. macrocephalus × C. gariepinus) were employed in the feed-trial experiments. Fish fed diet containing strain B44v (10(7) CFU/g feed) displayed not only no mortality but also growth improvement. At the end of the feed trial, fish were challenged by an intraperitoneal injection of Aeromonas hydrophila FW52. The Bacillus siamensis strain B44v fed fish survived (75.0%; p < 0.05) better than the controls (36.7%; p < 0.05) after a two week challenge. These collective results present for the first time the potential of Bacillus siamensis strain B44v for use as a bacterial probiotic in aquaculture.

    Full Text Available This study evaluated the apparent protein and energy digestibility of common feed ingredients (soybean meal, fish meal, wheat meal and corn by juvenile oscars using two different sampling intervals (30 min. and 12h. The 160 juvenile oscar fish tested (22.37 ± 3.06 g BW were divided into four cylindrical plastic net cages, each one placed in a 1000 L feeding tank. The experiment was completely randomized in a 2 x 4 factorial design (2 feces collection intervals and 4 feed ingredients with four replications. The statistical tests did not detect an interaction effect of sampling interval and type of ingredient on digestibility coefficients. Sampling interval did not affect protein and energy digestibility. The physical characteristics of juvenile oscar feces likely make them less susceptible to nutrient loss by leaching and can therefore be collected at longer intervals. Protein digestibility of the different ingredients was similar, showing that apparent digestibility of both animal and plant ingredients by juvenile oscars was efficient. Energy digestibility coefficients of fish meal and soybean meal were higher than those of wheat meal and corn. Carbohydrate-rich ingredients (wheat meal and corn had the worst energy digestibility coefficients and are therefore not used efficiently by juvenile oscars.O presente estudo avaliou a digestibilidade aparente da proteína e da energia de ingredientes (farelo de soja, farinha de peixe, farelo de trigo e milho por juvenis de apaiari (Astronotus ocellatus usando dois diferentes intervalos de coleta (30 min. e 12h.

    The Chernobyl fallout has so far caused contamination challenges for animal production in various areas of Norway for nearly 30 years, particularly for sheep, goats and reindeer. The persistent uptake and long-term trends of radiocaesium in forest and mountain areas still justifies maintaining the elevated permissible level for radiocaesium of 3,000 Bq/kg in reindeer meat. In comparison, Japanese authorities chose 100 Bq/kg as the permissible level for radiocaesium in Japanese foodstuffs. The slow decline in contamination levels in reindeer during the last 10-15 years have necessitated an evaluation of the remediation strategy for reindeer herding. The former seasonal differences in contamination levels in reindeer meat made 'early slaughtering' (in autumn instead of winter) an effective measure. However, such seasonal differences are no longer systematic, and differences in contamination levels in reindeer at slaughter now appear to be more strongly related to the differences in deposition levels in the areas grazed prior to slaughter. In 2011 Norwegian authorities (i.e. the Norwegian Reindeer Husbandry Administration, Norwegian Radiation Protection Authority, and the Geological Survey of Norway) therefore carried out an aerial survey covering 2,500 km{sup 2} of the most contaminated grazing areas to obtain more detailed information on geographical variability in deposition levels. The area included major parts of the grazing areas of three reindeer herding companies. The usefulness of deposition maps as bases for directing animal grazing to less contaminated areas depends on how well the total deposition correlate with the contamination levels in grazed vegetation. In the case of reindeer this covers both green plants and lichens. In 2012 the aerial survey was therefore supplemented by geo-referenced deposition measurements and sampling of various plant and lichen species at totally 17 sites ranging in deposition levels from 2.6 to 190 kBq/m{sup 2

    Full Text Available Optimization of the dietary formulation is the most effective way to reduce methane. Nineteen feed ingredients (brans, vegetable proteins, and grains were evaluated for their potential to generate methane and change methanogen diversity using an in vitro ruminal fermentation technique. Feed formulations categorized into high, medium and low production based on methane production of each ingredient were then subjected to in vitro fermentation to determine the real methane production and their effects on digestibility. Methanogen diversity among low, medium and high-methane producing groups was analyzed by PCR-DGGE. The highest methane production was observed in Korean wheat bran, soybean and perilla meals, and wheat and maize of brans, vegetable protein and cereal groups, respectively. On the other hand, corn bran, cotton seed meal and barley led to the lowest production in the same groups. Nine bacteria and 18 methanogen 16s rDNA PCR-DGGE dominant bands were identified with 83% to 99% and 92% to 100% similarity, respectively. Overall, the results of this study showed that methane emissions from ruminants can be mitigated through proper selection of feed ingredients to be used in the formulation of diets.

    Feed security, feed quality and issues surrounding the safety of raw materials are always of interest to all livestock farmers, feed manufacturers and competent authorities. These concerns are even more important when alternative feed ingredients, new product developments and innovative feeding trends, like insect-meals, are considered. The black soldier fly (Hermetia illucens) is considered a good candidate to be used as feed ingredient for aquaculture and other farm animals, mainly as an alternative protein source. Data on transfer of contaminants from different substrates to the insects, as well as the possible occurrence of toxin-producing fungi in the gut of non-processed insects are very limited. Accordingly, we investigated the impact of the substrate/diet on the intestinal mycobiota of H. illucens larvae using culture-dependent approaches (microbiological analyses, molecular identification through the typing of isolates and the sequencing of the 26S rRNA D1/D2 domain) and amplicon-based next-generation sequencing (454 pyrosequencing). We fed five groups of H. illucens larvae at the third growing stage on two substrates: chicken feed and/or vegetable waste, provided at different timings. The obtained results indicated that Pichia was the most abundant genus associated with the larvae fed on vegetable waste, whereas Trichosporon, Rhodotorula and Geotrichum were the most abundant genera in the larvae fed on chicken feed only. Differences in the fungal communities were highlighted, suggesting that the type of substrate selects diverse yeast and mold genera, in particular vegetable waste is associated with a greater diversity of fungal species compared to chicken feed only. A further confirmation of the significant influence of diet on the mycobiota is the fact that no operational taxonomic unit common to all groups of larvae was detected. Finally, the killer phenotype of isolated yeasts was tested, showing the inhibitory activity of just one species against

    Despite the importance of feedstuffs and feed ingredients in the food chain, few studies have analyzed the effectiveness of usual methods for the microbial decontamination of feeds. This work aimed to study the combined effect of temperature and organic acids (formic or lactic) on the inactivation of 10 isolates of Salmonella enterica and Escherichia coli obtained from vegetable feed ingredients, including cereals and other processed materials, in cattle feed. A central composite design was used with acid concentrations ranging from 0 to 0.2% (vol/wt) and temperatures from 50°C to 70°C. Second-order models were obtained to predict the survival inhibitions. The results reported in the present study indicate that temperature affects the survivability more significantly than acid concentration, whose effect was isolate dependent. However, after 2 min of treatment, optimal microbial inhibitions were generally achieved at temperatures above 65°C, using 0.1% formic acid or 0.2% lactic acid for Salmonella isolates and around 0.1% lactic acid or 0.2% formic acid for E. coli isolates, respectively. This work provides a set of guidelines helpful to reduce microbial contamination of feeds and highlights the importance of feed-ingredient monitoring to reduce pathogen contamination risk during feed processing.

To test the effects of a strategy that pairs positive stimuli (ie, stickers and cartoon packaging) with vegetables and presents them as the default snack. A randomized controlled trial was conducted with children who reported consumption of fewer than two servings of vegetables daily. Children (aged 3 to 5 years) in both control (n=12) and treatment (n=12) groups received a week's supply of plainly packaged (ie, generic) vegetables, presented by parents as a free choice with an alternative snack (granola bar), during baseline (Week 1) and follow-up (Week 4). During Weeks 2 and 3, the control group continued to receive generic packages of vegetables presented as a free choice, but the treatment group received vegetables packaged in containers with favorite cartoon characters and stickers inside, presented by parents as the default choice. Children in the treatment group were allowed to opt out of the vegetables and request the granola bar after an imposed 5-minute wait. General Linear Model repeated measures analysis of variance was conducted to compare vegetable and granola bar intake between control and treatment groups across the 4-week study. Both within- and between-subjects models were tested. A time×treatment interaction on vegetable intake was significant.

    Full Text Available ABSTRACT: This study evaluated the nutritional levels, apparent digestibility coefficients, and faecal characteristics of dogs fed with four by-products from bovine slaughter: testicles, residue sirloin steak, trachea, and liver. Ingredients were processed and packed in tins for heat treatment in autoclaves. For the digestibility and faeces quality, ingredients were mixed with a reference diet (commercial food in the proportion of 30g kg-1 test ingredient and 70g kg-1 reference diet (as dry matter. Ten adult dogs were distributed in double Latin block squares (5x5 with five treatments and five periods, totalling ten repetitions per treatment. The residue sirloin steak presented the highest levels of essential (414.2g kg-1 of dry matter and non-essential (399.0g kg-1 of dry matter amino acids in tested ingredients. No differences (P>0.05 were observed in apparent digestibility coefficients of dry matter - ADCDM (907g kg-1, ADCOM (930g kg-1, ADCCP (841g kg-1, ADCAEE (954g kg-1 values, and DE (5069kcal kg-1 and ME (4781kcal kg-1 values between testicle, residue sirloin steak, and liver. The trachea presented lower digestibility and energy values (digestible and metabolizable than the other ingredients. This lower trachea digestibility resulted in higher faecal volume for natural and dry matter (P0.05 in faecal score between ingredients. Ingredients tested in this study can be used in feeds for adult dogs; however, their nutritional levels and digestibility values should be considered for correct diet balance.

    Recently, both clinical and bench research has begun to provide scientific validation for the use of certain botanical ingredients. Related findings regarding proposed biological mechanisms of action have translated into clinical practice. Botanical compounds for which dermatologic and cosmetic applications have emerged include: olive oil, chamomile, colloidal oatmeal, oat kernal extract, feverfew, acai berry, coffee berry, curcumin, green tea, pomegranate, licorice, paper mulberry, arbutin, and soy. Many of these botanical sources offer biologically active components that require further in vitro and in vivo investigation in order for us to properly educate ourselves, and our patients, regarding over-the-counter products based on these ingredients.

    Hacking, W C; Mitchell, W R; Carlson, H C

    1978-01-01

    The frequency of Salmonella contamination of feedstuffs and finished broiler chicken feeds at an Ontario feed mill were investigated over a four-month period. Samples of feed ingredients and finished pelleted feeds were collected at various points during manufacture and cultured in trypticase soy broth prior to selective enrichment for isolation of Salmonella. Salmonella contamination was found in 4.3% of 93 finished pelleted broiler feeds examined. The contamination appeared to result primarily from the incorporation of contaminated animal protein ingredients into the feed. Meatmeal and the broiler, premix, which contained meatmeal as a filler, were most frequently contaminated followed by feather meal. Pelleting failed to eliminate the Salmonellae from the feeds. The methods used failed to detect Salmonella in the environment of the feed mill or its delivery trucks. Recommendations for control are made. PMID:369663

    To assess relationships between mothers' feeding practices (food as a reward, food for emotion regulation, modelling of healthy eating) and mothers' willingness to purchase child-marketed foods and fruits/vegetables (F&V) requested by their children during grocery co-shopping. Cross-sectional. Mothers completed an online survey that included questions about feeding practices and willingness (i.e. intentions) to purchase child-requested foods during grocery co-shopping. Feeding practices scores were dichotomized at the median. Foods were grouped as nutrient-poor or nutrient-dense (F&V) based on national nutrition guidelines. Regression models compared mothers with above-the-median v. at-or-below-the-median feeding practices scores on their willingness to purchase child-requested food groupings, adjusting for demographic covariates. Participants completed an online survey generated at a public university in the USA. Mothers (n 318) of 2- to 7-year-old children. Mothers who scored above-the-median on using food as a reward were more willing to purchase nutrient-poor foods (β=0·60, P<0·0001), mothers who scored above-the-median on use of food for emotion regulation were more willing to purchase nutrient-poor foods (β=0·29, P<0·0031) and mothers who scored above-the-median on modelling of healthy eating were more willing to purchase nutrient-dense foods (β=0·22, P<0·001) than were mothers with at-or-below-the-median scores, adjusting for demographic covariates. Mothers who reported using food to control children's behaviour were more willing to purchase child-requested, nutrient-poor foods. Parental feeding practices may facilitate or limit children's foods requested in grocery stores. Parent-child food consumer behaviours should be investigated as a route that may contribute to children's eating patterns.

    1997-10-01

    It has been known since the 1940s that nail polishes contain allergenic ingredients. The aim of this study was to clarify whether the nail polishes on the market today contain significant amounts of allergens, and what the solvents are. The following ingredients were determined: toluene, toluene sulfonamide formaldehyde resins, free formaldehyde, acrylates, methacrylates and certain organic solvents. The study comprised 20 brands and 42 samples. All the nail polishes analysed contained allergenic toluene sulfonamide formaldehyde resins (TSFR), in concentrations from 0.08 to 11.0%. The concentration of total formaldehyde varied from 0.02% to 0.5%. The more TSFR a nail polish contained, the higher was its formaldehyde content. Probably not only TSFR-allergic but also formaldehyde-allergic persons may get dermatitis from many of the nail polishes studied. The concentrations of acrylates and methacrylates were so small that they are of practical significance only to those previously sensitized to acrylates. Of the organic solvents, toluene was still widely used, whereas xylene was found in only 1 product. The nail polishes on the market today are not safe for all consumers. However, according to the regulations of the European Union, the packaging labeling of all cosmetic products must be supplied with a list of ingredients from the beginning of 1998. This will help the consumer to avoid allergenic products. A better alternative could, however, be to substitute the most allergenic ingredients with substances possessing minor allergy potency.

    2013-09-01

    Polyunsaturated fatty acids, docosahexaenoic acid (DHA, 22:6, n-3), eicosapentaenoic acid (EPA, 20:5, n-3), and arachidonic acid (ARA, 20:4 n-6), have multiple beneficial effects on human health and can be used as an important ingredient in dietary supplements, food, feed and pharmaceuticals. A variety of microorganisms has been used for commercial production of these fatty acids. The microorganisms in the Pythium family, particularly Pythium irregulare, are potential EPA producers. The aim of this work is to provide a safety assessment of P. irregulare so that the EPA derived from this species can be potentially used in various commercial applications. The genus Pythium has been widely recognized as a plant pathogen by infecting roots and colonizing the vascular tissues of various plants such as soybeans, corn and various vegetables. However, the majority of the Pythium species (including P. irregulare) have not been reported to infect mammals including humans. The only species among the Pythium family that infects mammals is P. insidiosum. There also have been no reports showing P. irregulare to contain mycotoxins or cause potentially allergenic responses in humans. Based on the safety assessment, we conclude that P. irregulare can be considered a safe source of biomass and EPA-containing oil for use as ingredients in dietary supplements, food, feed and pharmaceuticals.

    Billing and Sherman proposed the antimicrobial hypothesis to explain the worldwide spice use pattern. The present study explored whether two antimicrobial ingredients (i.e. spices and vinegar) are used in ways consistent with the antimicrobial hypothesis. Four specific predictions were tested: meat-based recipes would call for more spices/vinegar than vegetable-based recipes; summer recipes would call for more spices/vinegar than winter recipes; recipes in hotter regions would call for more spices/vinegar; and recipes including unheated ingredients would call for more spices/vinegar. Spice/vinegar use patterns were compiled from two types of traditional Japanese cookbooks. Dataset I included recipes provided by elderly Japanese housewives. Dataset II included recipes provided by experts in traditional Japanese foods. The analyses of Dataset I revealed that the vinegar use pattern conformed to the predictions. In contrast, analyses of Dataset II generally supported the predictions in terms of spices, but not vinegar.

    2006-09-01

    Full Text Available A study was conducted to compare live performance and digestive metabolism of broiler chickens fed all-vegetable diets (All-Veg compared to a regular diet including animal by-products. Three feeds were formulated and provided to broilers according to the feeding program: pre-starter from 1 to 10 days, starter from 11 to 21 days, and grower from 21 to 35 days. All feeds had corn and soybean meal as major ingredients; however, two of them were all-vegetable diets having either Degummed Soybean Oil (DSO or Acidulated Soybean Soapstock (ASS as fat sources. The third diet included poultry by-product and poultry fat. A total number of 360 day-old broiler chicks were allocated to 1m² battery cages, 10 chicks in each, and 12 replicates per treatment. Live performance was similar between groups of birds receiving the different diets with the exception of weight gain, which was increased for birds fed the All-Veg diet with ASS. Birds fed All-Veg diets had increased water intake and produced more excreta with a concurrent reduced feed metabolizability at both ages, regardless of fat source. Metabolizable Energy was not different for the three diets.

    In Campeche, Mexico, the Laguna de Términos has Thalassia testudinum beds inhabited by the grey snapper, Lutjanus griseus (Linnaeus 1758). Along one year, we collected 994 individuals and 672 had food in their stomachs; we recorded number, weight, and frequency oftrophic groups, and the index of relative importance. Dominant food components were Farfantepenaeus duorarum and Palemonetes octaviae, Eucinostomus gula (Cuvier 1830) and Libinia dubia. Salinity and temperature were related to the number of individuals collected and with greater fish consumption by large L. griseus. The trophic niche breadth index was calculated for six size-classes of fish. The smallest and the largest fish had the lowest index values, whereas medium-size snappers had higher values. This snapper has a preference for habitats with submerged vegetation. The percentage of fish with food in their stomachs was higher during dark hours, providing evidence of the nocturnal habits of this fish.

    The present study investigated nutritional programming in Atlantic salmon to improve utilisation of a vegetable-based diet. At first exogenous feeding, fry were fed either a marine-based diet (Diet Mstimulus, 80% fishmeal (FM)/4% fish oil (FO)) or a vegetable-based diet (Diet Vstimulus, 10% FM/0% FO) for 3 weeks. Subsequently, all fish were then fed under the same conditions with a commercial, marine-based, diet for 15 weeks and thereafter challenged with a second V diet (Diet Vchallenge, 10% FM/0% FO) for 6 weeks. Diploid and triploid siblings were run in parallel to examine ploidy effects. Growth performance, feed intake, nutrient utilisation and intestinal morphology were monitored. Fish initially given Diet Vstimulus (V-fish) showed 24 % higher growth rate and 23 % better feed efficiency compared with M-fish when later challenged with Diet Vchallenge. There was no difference in feed intake between nutritional histories, but increased nutrient retentions highlighted the improved utilisation of a V diet in V-fish. There were generally few significant effects of nutritional history or ploidy on enteritis scores in the distal intestine after the challenge phase as only V-triploids showed a significant increase (Pnutritional programming and the ability to respond better when challenged later in life may be attributed to physiological and/or metabolic changes induced by the stimulus. This novel study showed the potential of nutritional programming to improve the use of plant raw material ingredients in feeds for Atlantic salmon.

    Vermicomposting is a dependable waste recycling technology which greatly augments N and P levels mainly through microbial action. This paper aims to identify efficient N-fixing (NFB) and P-solubilizing (PSB) bacteria from earthworm intestines. Various combinations of vegetable market waste, rice straw, and cowdung were fed to two earthworm species (Eisenia fetida and Perionyx excavatus). Total organic C decreased, pH shifted towards neutrality, and NPK availability, and microbial (NFB, PSB, and total bacteria) population increased remarkably during vermicomposting with E. fetida. Therefore, 45 NFB and 34 PSB strains isolated from Eisenia gut were initially screened, their inter-dominance assessed, and 8 prolific strains were identified through 16SrRNA sequencing. Interestingly, two novel N-fixing strains of Kluyvera ascorbata emerged as an efficient biofertilizer candidate. Moreover, both N-fixing and P-solubilizing strains of Serratia and Bacillus were isolated from earthworm gut. All the isolated strains significantly improved soil health and facilitated crop growth as compared to commercial biofertilizers. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Rice (Oryza sativa) is the most important staple food for a large part of the world's human population, especially in East and South Asia, the Middle East, Latin America, and the West Indies. It provides more than one fifth of the calories consumed worldwide by the human. It is the second leading cereal crop and staple food of half of the world's population. It is grown in at least 114 countries with global production of 645 million tons; share of Asian farmers is about 90% of the total produce. Rice bran, brown outer layer of rice kernel, is mainly composed of pericarp, aleurone, subaleurone layer, and germ. It contains appreciable quantities of nutrients like protein, fat, and dietary fiber. Furthermore, it contains substantial amount of minerals like K, Ca, Mg, and Fe. Presence of antioxidants like tocopherols, tocotrienols, and γ-oryzanol also brighten prospects of rice bran utilization for humans as functional ingredient to mitigate the life-threatening disorders. Moreover, in the developing countries, budding dilemma of food crisis, arising due to lower crop yields and escalating population, needs to utilize each pent of available resources. To provide enough food to all people, there is the holistic approach of using the by-products generated during food processing and preparations. Rice is being processed in well-established industry, but the major apprehension is the utilization of its by-products; rice bran (5-8%) and polishing (2-3%) that are going as waste. Rice processing or milling produces several streams of materials including milled rice, bran, and husk. In developing countries, rice bran is considered as a by-product of the milling process and commonly used in animal feed or discarded as a waste. The potential of producing rice bran at the global level is 29.3 million tons annually, whereas the share of Pakistan is worked out to be 0.5 million tons. In present paper, attempt has been made to highlight the significance of these valuable but

    Conventional vegetable oil mills are complex plants, processing oil, fruits, or seeds to vegetable fats and oils of high quality and predefined properties. Nearly all by-products are used. However, most of the high valuable plant substances occurring in oil fruits or seeds besides the oil are used only in low price applications (proteins as animal feeding material) or not at all (e.g., phenolics). This chapter describes the state-of-the-art of extraction and use of oilseed/oil fruit proteins and phyto-nutrients in order to move from a conventional vegetable oil processing plant to a proper vegetable oil-biorefinery producing a wide range of different high value bio-based products.

    The effects of feeding Cistus ladanifer (Cistus) and a blend of soybean and linseed oil (1 : 2 vol/vol) on fatty acid (FA) composition of lamb meat lipids and messenger RNA (mRNA) expression of desaturase enzymes was assessed. In total, 54 male lambs were randomly assigned to 18 pens and to nine diets, resulting from the combination of three inclusion levels of Cistus (50 v. 100 v. 200 g/kg of dry matter (DM)) and three inclusion levels of oil (0 v. 40 v. 80 g/kg of DM). The forage-to-concentrate ratio of the diets was 1 : 1. Longissimus muscle lipids were extracted, fractionated into neutral (NL) and polar lipid (PL) and FA methyl esters obtained and analyzed by GLC. The expression of genes encoding Δ5, Δ6 and Δ9 desaturases (fatty acid desaturase 1 (FADS1), fatty acid desaturase 2 (FADS2) and stearoyl CoA desaturase (SCD)) was determined. Intramuscular fat, NL and PL contents were not affected by oil or Cistus. Oil supplementation reduced (PCistus alone had few effects on FA of NL but interacted with oil (PCistus and oil levels. The c9, t11-18:2 did not increase (PCistus dietary inclusion. Oil reduced c9-16:1, 17:0, c9-17:1,c9-18:1, 20:4n-6, 22:4n-6 and 20:3n-9 proportions in PL, and increased 18:2n-6, 18:3n-3, 20:3n-3 and of most of the biohydrogenation intermediates. The Cistus had only minor effects on FA composition of PL. Cistus resulted in a reduction (PCistus level, although a linear relationship with condensed tannins intake (P=0.11) could not be established. FADS1 mRNA expressed levels increased linearly (P=0.019) with condensed tannins intake. In summary, the inclusion of Cistus and oil in 1 : 1 forage-to-concentrate ratio diets resulted in a large increase in t10-18:1 and no increase in c9,t11-18:2 or n-3 long chain poor in polyunsaturated fatty acids in lamb meat.

    Increased substitution of marine ingredients by terrestrial plant products in aquafeeds has been proven to be suitable for Atlantic salmon farming. However, a reduction in n-3 long-chain PUFA is a consequence of this substitution. In contrast, relatively little attention has been paid to the effects of fishmeal and oil substitution on levels of micronutrients such as Se, considering fish are major sources of this mineral for human consumers. To evaluate the effects of dietary marine ingredient substitution on tissue Se distribution and the expression of Se metabolism and antioxidant enzyme genes, Atlantic salmons were fed three feeds based on commercial formulations with increasing levels of plant proteins (PP) and vegetable oil. Lipid content in flesh did not vary at any sampling point, but it was higher in the liver of 1 kg of fish fed higher PP. Fatty acid content reflected dietary input and was related to oxidation levels (thiobarbituric acid-reactive substances). Liver had the highest Se levels, followed by head kidney, whereas the lowest contents were found in brain and gill. The Se concentration of flesh decreased considerably with high levels of substitution, reducing the added value of fish consumption. Only the brain showed significant differences in glutathione peroxidase, transfer RNA selenocysteine 1-associated protein 1b and superoxide dismutase expression, whereas no significant regulation of Se-related genes was found in liver. Although Se levels in the diets satisfied the essential requirements of salmon, high PP levels led to a reduction in the supply of this essential micronutrient.

    Full Text Available Chicory is a perennial plant grown in different parts of the world, used as forage for livestock, as folklore remedies, or as a vegetable addition in human diets. There are several varieties of the chicory plant, known differently globally due to its numerous medicinal, culinary, and nutritional qualities. Most parts of the plant contain a potpourri of nutrients ranging within carbohydrates, proteins, vitamins, minerals, soluble fiber, trace elements, and bioactive phenolic compounds, which are responsible for the various nutritive, prophylactic, and therapeutic qualities of chicory. Inulin, coumarins, tannins, monomeric flavonoids, and sesquiterpene lactones are some of the major phytocompounds mostly found in chicory plants. The health-promoting activities attributed to chicory comprise, among others, anti-inflammatory, anticarcinogenic, antiviral, antibacterial, antimutagenic, antifungal, anthelmintic, immune-stimulating, and antihepatotoxic and its antioxidative qualities. As a versatile plant, chicory’s chemical composition and use as a suitable livestock feed supplement or as an alternative feed ingredient (AFI are thus reviewed.

    Boyer, Ivan J; Bergfeld, Wilma F; Heldreth, Bart; Fiume, Monice M; Gill, Lillian J

    The Cosmetic Ingredient Review (CIR) is a nonprofit program to assess the safety of ingredients in personal care products in an open, unbiased, and expert manner. Cosmetic Ingredient Review was established in 1976 by the Personal Care Products Council (PCPC), with the support of the US Food and Drug Administration (USFDA) and the Consumer Federation of America (CFA). Cosmetic Ingredient Review remains the only scientific program in the world committed to the systematic, independent review of cosmetic ingredient safety in a public forum. Cosmetic Ingredient Review operates in accordance with procedures modeled after the USFDA process for reviewing over-the-counter drugs. Nine voting panel members are distinguished, such as medical professionals, scientists, and professors. Three nonvoting liaisons are designated by the USFDA, CFA, and PCPC to represent government, consumer, and industry, respectively. The annual rate of completing safety assessments accelerated from about 100 to more than 400 ingredients by implementing grouping and read-across strategies and other approaches. As of March 2017, CIR had reviewed 4,740 individual cosmetic ingredients, including 4,611 determined to be safe as used or safe with qualifications, 12 determined to be unsafe, and 117 ingredients for which the information is insufficient to determine safety. Examples of especially challenging safety assessments and issues are presented here, including botanicals. Cosmetic Ingredient Review continues to strengthen its program with the ongoing cooperation of the USFDA, CFA, the cosmetics industry, and everyone else interested in contributing to the process.

  18. Aquaculture feed and food safety.

    Tacon, Albert G J; Metian, Marc

    2008-10-01

    The ultimate objective of an aquaculture feed manufacturer and aquaculture food supplier is to ensure that the feed or food produced is both safe and wholesome. Reported food safety risks, which may be associated with the use of commercial animal feeds, including compound aquaculture feeds, usually result from the possible presence of unwanted contaminants, either within the feed ingredients used or from the external contamination of the finished feed on prolonged storage. The major animal feed contaminants that have been reported to date have included Salmonellae, mycotoxins, veterinary drug residues, persistent organic pollutants, agricultural and other chemicals (solvent residues, melamine), heavy metals (mercury, lead, cadmium) and excess mineral salts (hexavalent chromium, arsenic, selenium, flourine), and transmissible spongiform encephalopathies. Apart from the direct negative effect of these possible contaminants on the health of the cultured target species, there is a risk that the feed contaminants may be passed along the food chain, via contaminated aquaculture produce, to consumers. In recent years, public concern regarding food safety has increased as a consequence of the increasing prevalence of antibiotic residues, persistent organic pollutants, and chemicals in farmed seafood. The important role played by the Food and Agriculture Organization of the United Nations (FAO) and the Codex Alimentarius Commission in the development of international standards, guidelines, and recommendations to protect the health of consumers and ensure fair practices in the food trade is discussed.

  19. Is your lunch salad safe to eat? Occurrence of bacterial pathogens and potential for pathogen growth in pre-packed ready-to-eat mixed-ingredient salads.

    Söderqvist, Karin

    2017-01-01

    As part of a trend toward healthy convenience foods, ready-to-eat (RTE) mixed-ingredient salads have become popular products among consumers. A mixed-ingredient salad contains combinations of raw (e.g. leafy vegetables and tomatoes) and processed (e.g. chicken, salmon, ham, pasta and couscous) ingredients. Contamination of leafy vegetables can occur during any step in the production chain and, since there is no step that kills pathogens, a completely safe final product can never be guaranteed. Meat ingredients, for example poultry meat and ham, are generally heat-treated before preparation, but may be contaminated after this treatment, e.g. when diced or sliced. When several ingredients are mixed together, cross-contamination may occur. Preparation of mixed-ingredient salads requires human handling, which presents an additional risk of bacterial contamination. With high-protein ingredients, e.g. cooked meat, the mixed-ingredient salad represents an excellent substrate for bacterial growth. This article reviews current knowledge regarding human bacterial pathogen prevalence in mixed-ingredient salads and the potential for pathogen growth in this product during storage.

    2007-03-01

    Full Text Available Indonesia is self sufficient in poultry production to meet the local demand for broiler and egg, mainly derived from modern poultry rather than the local village chicken. Feed may contribute up to 70% of total cost of poultry production. Poultry feed is formulated using least cost feed formulation technique to meet the bird requirement and composed by several ingredients both locally available and imported materials. Feed ingredients are classified based on energy sources, protein sources, agro-industrial by products, mineral sources and supplements. In many cases the poultry feed was supplemented with additives (antibiotics, enzymes, preservatives, etc. to improve animal performance. In 2005, Indonesian feed production reached almost 7 million tonnes and comprised around 85% as poultry feed, while the rest for aquaculture, swine and others. Poultry feed is based on corn-soy diet and average corn usage may reach more than 55% while soybean meal more than 23%. Ingredients requirement has been calculated based on the feed production and in order to fulfill the requirement. In 2006, Indonesia will import more than 1.6 million tonnes of corn from Argentina, USA and China, and more than 1.5 million tonnes of protein meal due to insufficiency of the local production. Major problems related in feed production are raw materials supply, quality and price fluctuation along with limited information. Several research have been conducted to use unconventional ingredients as protein sources such as local beans, leguminous seeds, leaf protein, animal by products but they were limited in availability. Research to improve protein level from carbohydrate source or by products had been attempted but it was not feasible for commercial feed industry. In future, technology innovation should be developed based on the existing problems related with feed industry including the areas to improve production efficiency, managing feed quality, processing technology and feed

The purpose of this study was to evaluate the potential use of A3 as a salmon feed ingredient in order to reduce reproduction of Caligus rogercresseyi in infested Atlantic salmon (Salmo salar. The toxicity of A3 was assessed histopathologically for 7 days, using intra-peritoneal injections of different doses (0, 0.24, 0.47, 2.37, 11.86, and 23.71 mg kg-1 in brain, intestine, skin, liver, and muscletissues of Salmosalar at the end of each treatment. The effect of A3 on sea lice was evaluated using 250 Atlantic salmon in an open-flow system of seawater (~13°C. The effect of the dosage in the fish diet was evaluated at two levels (9 mg kg-1, 18 mg kg-1 and considering a control (without A3 for 4, 8, and 12 days, once the sea lice had reached maturity. As a complement, the persistent effect of diluted A3 in sea water (0.5 g L-1 was evaluated at 10, 12, and 14°C for 0, 1, 3, 6, 10, and 15 days; and the maximum persistence was found at 10 days at 10°C. The results showed that the dosages over 0.47 mg kg-1 had no toxic effect on Atlantic salmon, but induced a detrimental effect on Caligus rogercresseyi (reduction of 15% of mature females with a dose of 18 mg kg-1, which could be attributed to alterations in the embryonic development of the sea lice.

  13. ENRICHMENT OF POULTRY PRODUCTS WITH FUNCTIONAL INGREDIENTS

    Directory of Open Access Journals (Sweden)

    Gordana Kralik

    2012-06-01

    Full Text Available Primary role of food is to provide nutritive stuffs in sufficient amounts to meet nutritive requirements. However, recent scientific findings confirm assumptions that particular food or its ingredients had positive physiological and psychological effects on health. Functional food is referred to food rich in ingredients, having beneficial effects on one or more functions in an organism. By consuming functional food consumers can expect some health benefits. Production of poultry products as functional food is getting more important on foreign markets while portion of such products on domestic food market is insignificant. The aim of this paper is to present possibilities for enrichment of poultry products, such as broiler and turkey meat and chicken eggs, as they can be characterized as functional food. Functional ingredients in poultry products are polyunsaturated fatty acids (LNA, EPA and DHA and antioxidants. Enrichment of poultry products with the stated ingredients that are beneficial for human health is subject of many researches, and only recently have researches been directed towards assessment of market sustainability of such products.

    Kynurenic acid (KYNA) was found to be an antagonist of iontropic glutamate receptors and alpha7 nicotinic acetylcholine receptors. Furthermore, it was documented that KYNA is an agonist of G-protein coupled GPR35 receptors which are mainly present in the gastrointestinal tract. It was also found that KYNA is present in the gastrointestinal tract and that its concentration gradually increases along it. The origin of KYNA in the gastrointestinal tract is not known. Both might be synthesized from tryptophan in it or absorbed from food and other dietary products. Therefore, the aim of the study was to investigate the concentration of KYNA in animal feed. The results indicate that the highest concentration of KYNA was found in animal feeds intended for livestock. The lower amount of KYNA was detected in animal feeds for fish. Interestingly, the lowest amount of KYNA was found in dog and cat feeds. Furthermore, an analysis of KYNA content in animal food ingredients was conducted. The concentration of KYNA found in one of the ingredients – rapeseed meal – was several times higher in comparison to animal feeds studied. The content of KYNA in the remaining feed ingredients tested was significantly lower. This is the first report on the concentration of KYNA in animal feeds. There is a need for further detailed analysis leading to establishing a set of guidelines for animal feeding. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

    survey and types of fruits consumed for this species, we used information from the literature complemented with results obtained from analyses of the digestive content collected from captured fish and from the main fisheries landing and market in Manaus, the Panair fair. Fifteen digestive tracts were collected weekly at the fair, during nine months. The digestive tract were removed and put in plastic bags, stored in styrofoam boxes with ice and brought to the laboratory, where they remained in the freezer (-20ºC. Analyses of the digestive tract contents consisted of the fruits and seeds collected, preserved in alcohol 70% and identified from the digestive tracts, constituting a reference collection. After identification, fruits and seeds species collected from the varzea and igapo areas were collected for proximate analyses, according to A.O.A.C (1995 and crude energy (kJ/g using a calorimetric bomb. 46 vegetation species distributed in 21 families and classified into nine types of fruits were identified. According to our data, tambaqui feeds encompass at least 133 species, between fruits and seeds, from 38 families and 15 types of fruits. Consumption of these items varied between triturated and/or whole. Proximate analyses from 14 seeds and 40 fruits species demonstrated that these items are more energetic than proteinous.

    Full Text Available The history of cosmetics develops in parallel to the history of man, associated with fishing, hunting, and superstition in the beginning, and later with medicine and pharmacy. Over the ages, together with human progress, cosmetics have changed continuously and nowadays the cosmetic market is global and highly competitive, where terms such as quality, efficacy and safety are essential. Consumers’ demands are extremely sophisticated, and thus scientific research and product development have become vital to meet them. Moreover, consumers are aware about environmental and sustainability issues, and thus not harming the environment represents a key consideration when developing a new cosmetic ingredient. The latest tendencies of cosmetics are based on advanced research into how to interfere with skin cell aging: research includes the use of biotechnology-derived ingredients and the analysis of their effects on the biology of the cells, in terms of gene regulation, protein expression and enzymatic activity measures. In this review, we will provide some examples of cosmetic active ingredients developed through biotechnological systems, whose activity on the skin has been scientifically proved through in vitro and clinical studies.

    2013-01-01

    Animal feed can be contaminated with various mycotoxins. To ensure animal health and safe food and feed production, the European Commission has recommended increased monitoring of the co-occurrence of deoxynivalenol, zearalenone, ochratoxin A, fumonisin B(1) and B(2), T-2 and HT-2 toxin in feed. Thus, there is a need for an analytical method that enables their simultaneous detection and quantification. This paper describes the development and in-house validation of such a method, in which the mycotoxins were extracted from spiked and naturally contaminated cereal-based compound feed, corn and wheat. The extracts were divided into two aliquots where one was diluted and then analysed directly and the other was cleaned by using MultiSep(®)226 and then diluted and analysed. Separation and detection was achieved with LC-ESI-MS/MS by using a triple quadrupole instrument in the SRM mode. The precision (in terms of intra-day repeatability and inter-day reproducibility), accuracy, linearity, apparent recovery and expanded measurement uncertainty in feed, corn and wheat were evaluated. The LODs ranged from 1.0 to 72 μg/kg, and the LOQs ranged from 2.5 to 115 μg/kg. The apparent recovery was higher than 86% for all the mycotoxins, and the precision was better than that defined by the Horwitz equation for all concentrations. Proficiency test materials were analysed to assess the accuracy of the method, and the results were satisfactory for all seven mycotoxins. The method will be used to monitor the occurrence of these mycotoxins in products intended for animal feeding in Sweden.

    Of 700 animal feed samples, 32 (4.5%) harbored Salmonella. The highest percentage of contamination was found in sheep feed and local protein. A total of 17 Salmonella serotypes were identified. The most frequent serotypes were Salmonella meleagridis. S. bornum, S. montevideo, and S. drypool. S. bornum was isolated for the first time in Iraq and from both local feed and its ingredients. The common somatic group found was that of Salmonella group C; then came groups E, G, B, and D. Three serotypes (S. enteritidis, S. california, and S. muenchen) seemed to form a link of infection among feed, food, patients, and carriers. PMID:453836

    Vegetable oils are obtained by mechanical extraction or cold pressing of various parts of plants, most often: seeds, fruits, and drupels. Chemically, these oils are compounds of the ester-linked glycerol and higher fatty acids with long aliphatic chain hydrocarbons (min. C14:0). Vegetable oils have a variety of properties, depending on their percentage of saturation. This article describes sea-buckthorn oil, which is extracted from the well characterized fruit and seeds of sea buckthorn. The plant has a large number of active ingredients the properties of which are successfully used in the cosmetic industry and in medicine. Valuable substances contained in sea-buckthorn oil play an important role in the proper functioning of the human body and give skin a beautiful and healthy appearance. A balanced composition of fatty acids give the number of vitamins or their range in this oil and explains its frequent use in cosmetic products for the care of dry, flaky or rapidly aging skin. Moreover, its unique unsaturated fatty acids, such as palmitooleic acid (omega-7) and gamma-linolenic acid (omega-6), give sea-buckthorn oil skin regeneration and repair properties. Sea-buckthorn oil also improves blood circulation, facilitates oxygenation of the skin, removes excess toxins from the body and easily penetrates through the epidermis. Because inside the skin the gamma-linolenic acid is converted to prostaglandins, sea-buckthorn oil protects against infections, prevents allergies, eliminates inflammation and inhibits the aging process. With close to 200 properties, sea-buckthorn oil is a valuable addition to health and beauty products.

    Mothers' goals are important for health behavior change, and engagement in child obesity interventions. It is unknown if maternal feeding goals are associated with observed home mealtime or feeding practices. The objective of this study was to examine the association of four common feeding goals (restrict junk food, promote fruit or vegetable intake, promote autonomy in eating and prevent obesity) with mothers' observed home mealtime and feeding practices. Low-income mothers (N = 265) of children (mean child age 70.8 months) participated in a semi-structured interview about child feeding. A coding scheme was developed and reliably applied to identify mothers' feeding goals from transcripts. Mothers' observed home mealtime and feeding practices were reliably coded from home mealtimes and a laboratory eating protocol. Mothers completed a questionnaire and reported demographics. Participant weights and heights were obtained. Regression models were used to test the association of each feeding goal with observed maternal practices, controlling for covariates. The goal of restricting junk food was associated with the child always eating at a table (OR 2.87, 95% CI (1.39-5.96) p = 0.005), but not with the mother restricting junk food. The goal of promoting fruit or vegetable intake was associated with observationally promoting vegetables (OR 1.41, 95% CI (1.09-1.84), p = 0.01). The goals of promoting autonomy and preventing obesity were not associated with any observed maternal home mealtime or feeding practices. While mothers' goals to restrict junk food and promote fruit or vegetable intake were associated with observed home mealtime and feeding practices, promoting autonomy and preventing obesity were not. Increased understanding of why low-income mothers may not translate certain feeding goals into practices may inform childhood obesity interventions. © 2016 John Wiley & Sons Ltd.

  15. Our unrequited love for natural ingredients.

    Burdock, George A; Wang, Wendan

    2017-09-01

    Naturally sourced food ingredients have been the beneficiary of legal, regulatory and consumer preference as the result of a widely shared assumption of safety. However, the natural substances consumed in modernity may have little to do with the historically consumed part of the plant or even the plant itself. Further, our initial impression of a safe plant derivative may well be false as the result of the use of different growth conditions or, changes in harvesting and processing conditions that may have brought about a higher level of toxic constituents. Despite the variability of plant constituents, manufacturers' standards are set according to the content of commercially desirable properties, rather than presence of potentially toxic constituents. Why then, after all the potential reservations regarding naturals, is there such an enmity toward synthetic chemicals (including single chemical fermentation products), which have been tested in a systematic manner for potential toxic effects and whose composition is well known as the result of consistent manufacturing techniques and analytical controls? The authors will describe the paradigms used for natural products safety review and compare them with the safety criteria required for an "artificial" food ingredient. Copyright © 2017 Elsevier Ltd.

    This study examined the relationship between mindful feeding as a novel construct and parent-reported child dietary intake. Participants (N=497) were parents of children ages 2.9 to 7.5 recruited through Amazon Mechanical Turk (MTurk). Parents were primarily non-Hispanic white (79%) and female (76%). Simple and hierarchical regression analyses were conducted to examine the associations between parental mindful feeding (i.e., parent mental and emotional presence while feeding a child) and their children's dietary intake. Mindful feeding accounted for 5.1% of the unadjusted variance in child fruit and vegetable intake. Mindful feeding accounted for 4.2% of the unadjusted variance in child added sugar consumption after accounting for relevant covariates. Specifically, higher parental mindful feeding predicted higher fruit and vegetable intake and lower sugar intake among children. Mindful feeding was associated with almost all indicators of healthier child diet, indicating great potential for this approach to improve child health. If incorporated into general or health-focused interventions for parents, mindfulness could significantly improve child health outcomes. Further development and validation of the Mindful Feeding Questionnaire is also recommended, as it could become a useful survey tool to assess for this construct. Copyright © 2016 Elsevier Ltd.

    2018-01-22

    Elimination dietary trials for the diagnosis of adverse food reactions (food allergies) in dogs and cats are often conducted with commercial pet foods while relying on their label to select those not containing previously-eaten ingredients. There are concerns that industrial pet foods might contain unlisted food sources that could negate the usefulness of performing food trials. Furthermore, unidentified ingredients might cause clinical reactions in patients hypersensitive to such items. We searched two article databases on July 7, 2017 and January 12, 2018 for relevant articles, and we screened abstracts from the leading international veterinary dermatology congresses for suitable material. Additional citations were found in the selected papers. In all, we extracted data from 17 articles and one abstract. The studies varied both in the number of pet foods tested (median: 15; range: 1 to 210) and that of ingredients specifically evaluated (median: 4; range: 1 to 11). Studies most often employed either PCR to detect DNA or ELISA to identify proteins from one or more vegetal or animal species; two studies used mass spectrometry to increase the number of detectable proteins. The various methods found ingredients that were not on the label in 0 to 83% (median: 45%) of tested diets; this percentage varied between 33 and 83% in pet foods with "novel/limited" ingredients proposed for elimination diets. Similarly, ingredients were found to be missing from the label in 0 to 38% (median: 1%) of tested foods. Finally, six studies evaluated, among others, several hydrolysate-containing pet foods: mislabeling with unlabeled or missing ingredients was found only in one diet. The mislabeling of pet foods appears rather common, even in those with "novel" or "limited" ingredients proposed for elimination diets. Unexpected added ingredients are more frequently detected than those missing from the label. There is insufficient information to determine if the presence of a

    There is a constant need for developing new fragrance ingredients in the flavor and fragrance industry, as it allows perfumers to create unique and differentiating perfumes for fine as well as functional products. Among all the categories of notes used in perfume creation, amber notes are indispensible and ubiquitous in their presence in all perfumes. Not only amber notes impart high performance and substantivity to fragrances, but they are paramount in the development of classic and legendary fragrances. This article is based on the plenary lecture delivered at the flavor & fragrance 2013 conference of the German Chemical Society in Leipzig, Germany. The strategy, rationale, and the various synthetic approaches that led to the discovery of two new very powerful, woody, amber materials, Amber Xtreme(®) (1) and Trisamber(®) (2), are delineated.

    There has been continuing interest and support in using herbaceous biomass, mostly agricultural crop residues, in the U.S. as feedstocks for producing bioenergy, liquid transportation fuels, and industrial chemicals/materials. With the potential of greater collection of agricultural crop residues for the foregoing industrial applications there will be a commensurate greater availability of crop residues for utilization in agricultural production. Agricultural crop residues are typically used in agricultural production as roughage or bedding for cattle. Use of herbaceous biomass, corn stover of greatest interest at the present time, and processing coproducts thereof, as a feed ingredient presents an opportunity to reduce ration costs and improve livestock enterprise profitability by replacing an amount of corn and other feed grains in livestock diets with proper formulation. The obvious advantage of utilizing corn stover is its wide availability and low cost.

    Calendula officinalis extract, C officinalis flower, C officinalis flower extract, C officinalis flower oil, and C officinalis seed oil are cosmetic ingredients derived from C officinalis. These ingredients may contain minerals, carbohydrates, lipids, phenolic acids, flavonoids, tannins, coumarins, sterols and steroids, monoterpenes, sesquiterpenes, triterpenes, tocopherols, quinones, amino acids, and resins. These ingredients were not significantly toxic in single-dose oral studies using animals. The absence of reproductive/developmental toxicity was inferred from repeat-dose studies of coriander oil, with a similar composition. Overall, these ingredients were not genotoxic. They also were not irritating, sensitizing, or photosensitizing in animal or clinical tests but may be mild ocular irritants. The Cosmetic Ingredient Review (CIR) Expert Panel concluded that these ingredients are safe for use in cosmetics in the practices of use and concentration given in this amended safety assessment.

  18. 100% Organic Poultry Feed: Can Algae Replace Soybean Expeller in Organic Broiler Diets?

    Directory of Open Access Journals (Sweden)

    Catherine L. Gerrard

    2013-12-01

    Full Text Available Current EU regulations allow 5% of feed for organic poultry to come from non-organic production. This is due to concerns about a 100% organic diet meeting the requirements for specific amino acids such as methionine. This exception is due to end on 31st December 2017. While this may match consumer expectations, protein sourced from global organic production may have a negative impact on perceptions of organic poultry in other ways. Soybean is a commonly used ingredient in poultry feed but soybean production has negative environmental and social impacts. Consumers may also prefer organic poultry to have been fed on locally produced feed and, indeed, this would be in line with organic principles. Preliminary feasibility feed trials were carried out during a summer and a winter season using organic broilers in the UK to test three 100% organic feeds: a control diet with globally sourced ingredients including soybean expeller, a diet based on locally sourced (i.e. within Europe organic ingredients, and a diet based on locally sourced organic ingredients and algae (a good source of methionine. The results of the summer feed trial showed that there were no significant differences in broiler weight gains. In the winter feed trial differences were found. There was a significant difference (P = 0.034 in weight gain between the local feed (lower weight gain and the local feed with algae but no significant difference between the control diet with soybean and the two local diets. These preliminary feed trials indicate that there is no significant impact on broiler performance or animal welfare parameters when replacing soybean with European protein sources, possibly including algae, suggesting that, although the research is still at a very early stage, such feeds may be a viable option for 100% organic poultry feed in the future.

    Brittle stars (Ophiura spp.) and other benthic macrofauna were collected in a prospective mariculture area in the North Sea to determine if these taxa could be used as indicator species to track nutrients released from future offshore aquaculture sites. We analysed natural carbon and nitrogen stable isotopic signatures in tissues from macrofauna and compared these to six feed ingredients and four experimental diets made thereof, as well as to a commercial feed with and without lipid and carbonate removal. Our data suggest practicability of using isotopic signatures of Ophiura spp. to track aquaculture-derived organic material if plant-based fish diet ingredients and commercial feed were used for fish farming in the German Exclusive Economic Zone. Diets with high fish meal content would not be detected in Ophiura spp. using isotopic measures due to the similarity with the marine background. Our data provide valuable baseline information for studies on the impact of offshore aquaculture on the marine environment.

    Polyphenols are secondary plant metabolites with antioxidant, anti-inflammatory and anti-microbial activity. They are ubiquitously distributed in the plant kingdom; high amounts contain, for example, green tea and grape seeds. Polyphenolic extracts are attractive ingredients for cosmetics and pharmacy due to their beneficial biological properties. This review summarizes the effects of polyphenols in the context of anti-ageing activity. We have explored in vitro studies, which investigate antioxidant activity, inhibition of dermal proteases and photoprotective activity, mostly studied using dermal fibroblasts or epidermal keratinocytes cell lines. Possible negative effects of polyphenols were also discussed. Further, some physicochemical aspects, namely the possible interactions with emulsifiers and the influence of the cosmetic formulation on the skin delivery, were reported. Finally, few clinical studies, which cover the anti-ageing action of polyphenols on the skin after topical application, were reviewed. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    Full Text Available Thirty-five available feeds were fermented in vitro in order to investigate their soluble total organic carbon (TOCs and methane (CH4 production rate. A fermentation reactor was designed to capture the CH4 gas emitted and to collect liquor from the reactor during in vitro fermentation. The results showed that CH4 production rate greatly varied among feeds with different ingredients. The lowest CH4-producing feeds were corn gluten feed, brewer’s grain, and orchard grass among the energy, protein, and forage feed groups, respectively. Significant differences (p<0.05 were found in digestibility, soluble total organic carbon (TOCs, and CH4 emissions among feeds, during 48 h of in vitro fermentation. Digestibility and TOCs was not found to be related due to different fermentation pattern of each but TOCs production was directly proportional to CH4 production (y = 0.0076x, r2 = 0.83. From this in vitro study, TOCs production could be used as an indirect index for estimation of CH4 emission from feed ingredients.

    Ofori, Jack A; Hsieh, Yun-Hwa P

    2014-01-01

    Blood has traditionally been used as a high protein ingredient in both human food and animal feed, with resulting economic, environmental and nutritional benefits. However, potentially serious health and safety issues related to blood consumption, particularly the risk of pathogenic or harmful metabolic materials, the infectivity of prion diseases, and the presence of identified allergens such as bovine serum albumin (BSA), are causing many consumers to shy away from any product containing either animal blood or ingredients derived from animal blood. Thus, despite the significant volumes of blood produced by slaughterhouses, blood is currently underutilized as a food ingredient. This article reviews the use of animal blood as an ingredient in food intended for human consumption or for animal feed and discusses the related consumer concerns.

    Feed is a potential and major source for introducing Salmonella into the animal-derived food chain. This is given special attention in the European Union (EU) efforts to minimize human food-borne Salmonella infections from animal-derived food. The objective of this study was to estimate the total extra cost for preventing Salmonella contamination of feed above those measures required to produce commercial feed according to EU regulation (EC) No 183/2005. The study was carried out in Sweden, a country where Salmonella infections in food-producing animals from feed have largely been eliminated. On the initiative and leadership of the competent authority, the different steps of feed production associated with control of Salmonella contamination were identified. Representatives for the major feed producers operating in the Swedish market then independently estimated the annual mean costs during the years 2009 and 2010. The feed producers had no known incentives to underestimate the costs. The total cost for achieving a Salmonella-safe compound feed, when such a control is established, was estimated at 1.8-2.3 € per tonne of feed. Of that cost, 25% relates to the prevention of Salmonella contaminated high-risk vegetable feed materials (mainly soybean meal and rapeseed meal) from entering feed mills, and 75% for measures within the feed mills. Based on the feed formulations applied, those costs in relation to the farmers' 2012 price for compound feed were almost equal for broilers and dairy cows (0.7%). Due to less use of protein concentrate to fatten pigs, the costs were lower (0.6%). These limited costs suggest that previous recommendations to enforce a Salmonella-negative policy for animal feed are realistic and economically feasible to prevent a dissemination of the pathogen to animal herds, their environment, and potentially to human food products.

  8. Robotic milking: Feeding strategies and economic returns.

    Bach, Alex; Cabrera, Victor

    2017-09-01

    Cows in herds equipped with conventional milking parlors follow a structured, consistent, and social milking and feeding routine. Furthermore, in most cases cows in conventional herds receive all their nutrients from a total mixed ration, whereas in herds equipped with robotic or automatic milking systems (AMS) a fraction of their nutrients is provided during milking, mainly as a means to attract cows to the milking system. In this regards, AMS present both a challenge and an opportunity for feeding cows. The main challenge resides in maintaining a minimum and relatively constant milking frequency in AMS. However, milking frequency is dependent on many factors, including the social structure of the herd, the farm layout design, the type of traffic imposed to cows, the type of flooring, the health status of the cow (especially lameness, but also mastitis, metritis, among others), the stage of lactation, the parity, and the type of ration fed at the feed bunk and the concentrate offered in the AMS. Uneven milk frequency has been associated with milk losses and increased risk of mastitis, but most importantly it is a lost opportunity for milking the cow and generating profit. On the other hand, the opportunity from AMS resides in the possibility of milking more frequently and feeding cows more precisely or more closely to their nutrient needs on an individual basis, potentially resulting in a more profitable production system. But, feeding cows in the parlor or AMS has many challenges. On one side, feeding starchy, highly palatable ingredients in large amounts may upset rumen fermentation or alter feeding behavior after milking, whereas feeding high-fiber concentrates may compromise total energy intake and limit milking performance. Nevertheless, AMS (and some milking parlors, especially rotary ones) offer the possibility of feeding the cows to their estimated individual nutrient needs by combining different feeds on real time with the aim of maximizing profits rather

    Currently, there is a great tendency in cosmetic area to use natural extracts. Coffee silverskin (CS) is the most abundant solid by-product generated during roasting of coffee processing. To evaluate different CS extracts as promising cosmetic ingredients, regarding antioxidant, antimicrobial, and cytotoxic properties. Aqueous, hydroalcoholic and ethanolic CS extracts were obtained by an environmentally friendly procedure considering costs and pollution. Extracts were characterized for total phenolic and flavonoid contents (TPC and TFC, respectively), antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), antimicrobial activity expressed as minimal inhibitory concentration (MIC) and cytotoxicity using the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) and lactate dehydrogenase (LDH) assays in two skin cell lines (fibroblasts and keratinocytes). The TPC of extracts was 18.33-35.25 mg of gallic acid equivalents per g of material on a dry basis (mg GAE/g db). The TFC of extracts was 1.08-2.47 µg cathechin equivalents per g dry material (µg CE/g db). The antioxidant activity was high, with values ranging between 95.95 and 216.40 µmol Fe(2+)/g for aqueous and alcoholic samples, respectively. Preliminary assays for antimicrobial potential showed that extracts display antibacterial activity. The MIC varied from 31.3 to 250 µg/mL for Gram-positive, and from 31.3 to 1000 µg/mL for Gram-negative. Extracts did not affect in vitro cell viability, with values near 100% in all concentrations tested. RESULTS seem show that CS is a safe source of natural antioxidants with antifungal and antibacterial activity and no cytotoxicity, with potential usefulness for cosmetic applications.

    2014-07-01

    Naturally occurring radionuclides are generally considered being respective part of the environment and hence no statutory monitoring of their levels are required in food products. Therefore, limited data are available on the naturally occurring radionuclides in food. Dairy products constitute a significant portion of Finnish diet (400-500 g/d) and hence it is reasonable to study radionuclide levels in milk in more detail. Contrary to caesium, strontium and iodine, few transfer coefficients are available in the literature for naturally occurring radionuclide transfer to cow's milk. The renaissance of mining industry in Finland has raised a question among the public about the baseline values of naturally occurring radionuclides in Finnish agricultural products. The objective of this study was to investigate naturally occurring radionuclides in the components of dairy cattle diet and milk and calculate their transfer to milk. This information is needed for regulating the permitted discharges to the environment and for setting up monitoring programs if any unplanned discharges are released. In modern dairy farming, cattle are fed a precise diet in order to maximize milk production and quality and to achieve cost-effectiveness. Therefore, several different components are found in dairy cattle's diet and pasture grass concentrations are not sufficient for calculating radionuclide transfer to cow's milk. In this study, we carried out comprehensive sampling at four dairy farms each representing different areas of natural radiation background. The pasture soils were characterized and measured for natural radioactivity. Samples were taken from cattle's total diet (including e.g. pasture grass, water, silage, mineral forage) and milk.

    Full Text Available The growth of the non-ruminant sector to self–sufficiency in meat and eggs has been matched by massive importation of feed. Thus, a major thrust to reduce the burden of feed imports is to increase the use of indigenous feed resources and intensify research to look for alternatives and substitutes. Over the past 3 decades, local researchers have reported on the availability nutritive content, optimal inclusion levels and treatment methods to enhance nutrient value of many locally available feed ingredients in practical poultry rations. The list includes evaluation and utilization of feed rice, palm kernel cake (PKC, broken rice, bran, sorghum, cassava, sago, fishmeal and commercial grain corn production; but the goal of import substitution and self- sufficiency is still unfulfilled. Although PKC, feed rice, local maize and specialty fats has potential to be viable energy feed sources and local fish meal is a promising protein feed source, more large scale Research and Development (R & D is needed. In the ruminant sub-sector, emphasis is towards maximizing use of locally available agro-industrial byproducts and crop residues for the production of cost-effective feeds. The utilization of local feed resources is highly dependent on the supply of agro- industrial byproducts or crop residues from the oil palm and rice industries. In order to encourage a sustainable ruminant industry in Malaysia, local feed production has to be maximized and strengthened. Current emphasis is towards the development of practical and low-cost feeds for various classes of livestock species, particularly by utilizing local forages, tree fodders, crop residues and agro-industrial byproducts. This paper highlights the research and development on animal feed in Malaysia over the last three decades and discusses various aspects of livestock feeding.

    Alfalfa (Medicago sativa) has been extensively used as animal feed, due to its fiber, protein, minerals, and vitamins, being also a useful source of phenolic compounds with potential therapeutic benefits. Nevertheless, its potential use as human ingredient is scarce. The aim of this work was to assess the nutritional composition, amino acid profile, and antioxidant capacity (AOC) of freeze-dried juice (FDJ) and fibrous residual material (RM), two new alfalfa-derived products (Adps) recently launched as ingredients for beverage preparations. Results demonstrated a high content of proteins (23-30 g/100 g FDJ and 13-17 g/100 g RM), crude fiber (29 g/100 g RM), and minerals (such as sodium, calcium, iron, and zinc). No significant difference was found in caloric content (4 kcal/g). Essential and nonessential amino acids were quantified in both Adps being leucine and lysine the most abundant. Total phenolic and total flavonoid contents (TPC and TFC, respectively) and their changes along the different harvesting periods of the year were also examined. FDJ presented the highest TPC in May (19 mg gallic acid equivalents/g dry weight [dw]), while in October TFC had the maximum value (4 mg catechin equivalents/g dw). Both products exhibited an interesting AOC by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power assays. This study reports the nutraceutical potential of two new types of Adps.

    In few years Danish organic protein crops may be used as ingredients in feed for organic fish in partial replacement of fish meal protein. Fish meal is currently the primary protein source in feed for organic fish. Fish meal is manufactured by industrial fish caught among sustainable stocks, but even natural this protein source is not defined as organic and is as well a limited resource. Therefore, it is necessary to replace as much as possible of the fish meal protein with competitive o...

    Over the last years, continuous manufacturing has created significant interest in the pharmaceutical industry. Continuous filtration at low flow rates and high solid loadings poses, however, a significant challenge. A commercially available, continuously operating, dynamic cross-flow filtration device (CFF) is tested and characterized. It is shown that the CFF is a highly suitable technology for continuous filtration. For all tested model active pharmaceutical ingredients, a material-specific strictly linear relationship between feed and permeate rate is identified. Moreover, for each tested substance, a constant concentration factor is reached. A one-parameter model based on a linear equation is suitable to fully describe the CFF filtration performance. This rather unexpected finding and the concentration polarization layer buildup is analyzed and a basic model to describe the observed filtration behavior is developed. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

  11. Lactose in dairy ingredients: Effect on processing and storage stability.

    2016-08-01

    Lactose is the main carbohydrate in the milk of most species. It is present in virtually all dry dairy ingredients, with levels ranging from powders. The presence of lactose has a strong effect on ingredient processing and stability. Lactose can negatively influence powder properties and lead to undesirable effects, such as the stickiness of powder resulting in fouling during drying, or caking and related phenomena during storage. In addition, being a reducing carbohydrate, lactose can also participate in the Maillard reaction with free amino groups of proteins, peptides, and free AA. In this review, the influence of the presence (or absence) of lactose on physiochemical properties of dairy ingredients is reviewed, with particular emphasis on behavior during processing and storage. Particularly important features in this respect are whether lactose is in the (glassy) amorphous phase or in the crystalline phase, which is strongly affected by precrystallization conditions (e.g., in lactose, permeate, and whey powders) and by drying conditions. Furthermore, the moisture content and water activity of the ingredients are important parameters to consider, as they determine both mobility and reactivity, influencing Maillard reactions and concomitant browning, the crystallization of amorphous lactose during storage of dairy ingredients, glass transitions temperatures, and associated stickiness and caking phenomena. For the stickiness and caking, a crucial aspect to take into account is powder particle surface composition in relation to the bulk powder. Lactose is typically underrepresented at the powder surface, as a result of which deviations between observed lactose-induced caking and stickiness temperatures, and determined glass transition temperatures arise. By considering lactose as an integral part of ingredient composition along with all other compositional and environmental properties, lactose behavior in dairy ingredients can be understood, controlled, and

    Half of the seafood consumed globally now comes from aquaculture, or farmed seafood. Aquaculture therefore plays an increasingly important role in the global food system, the environment, and human health. Traditionally, aquaculture feed has contained high levels of wild fish, which is unsustainable for ocean ecosystems as demand grows. The aquaculture industry is shifting to crop-based feed ingredients, such as soy, to replace wild fish as a feed source and allow for continued industry growth. This shift fundamentally links seafood production to terrestrial agriculture, and multidisciplinary research is needed to understand the ecological and environmental health implications. We provide basic estimates of the agricultural resource use associated with producing the top five crops used in commercial aquaculture feed. Aquaculture's environmental footprint may now include nutrient and pesticide runoff from industrial crop production, and depending on where and how feed crops are produced, could be indirectly linked to associated negative health outcomes. We summarize key environmental health research on health effects associated with exposure to air, water, and soil contaminated by industrial crop production. Our review also finds that changes in the nutritional content of farmed seafood products due to altered feed composition could impact human nutrition. Based on our literature reviews and estimates of resource use, we present a conceptual framework describing the potential links between increasing use of crop-based ingredients in aquaculture and human health. Additional data and geographic sourcing information for crop-based ingredients are needed to fully assess the environmental health implications of this trend. This is especially critical in the context of a food system that is using both aquatic and terrestrial resources at unsustainable rates. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    The key issue of the safety assessment of botanical ingredients in personal care products (PCP) is the phytochemical characterisation of the plant source, data on contamination, adulteration and hazardous residues. The comparative approach used in the safety assessment of GM-plants may be applied to novel botanical PCP ingredients. Comparator(s) are the parent plant or varieties of the same species. Chemical grouping includes definition of chemical groups suitable for a read-across approach; it allows the estimation of toxicological endpoints on the basis of data from related substances (congeneric groups) with physical/chemical properties producing similar toxicities. The Threshold of Toxicological Concern (TTC) and Dermal Sensitisation Threshold (DST) are tools for the assessment of trace substances or minor ingredients. The evaluation of skin penetration of substances present in human food is unnecessary, whereas mixtures may be assessed on the basis of physical/chemical properties of individual substances. Adverse dermal effects of botanicals include irritation, sensitisation, phototoxicity and immediate-type allergy. The experience from dietary supplements or herbal medicines showed that being natural is not equivalent to being safe. Pragmatic approaches for quality and safety standards of botanical ingredients are needed; consumer safety should be the first objective of conventional and botanical PCP ingredients.

    Natural ingredients have been used traditionally for millennia and their application in topical creams, lotions and preparations within the traditional medicines and healing traditions of many cultures has been observed. Over the last 20 years, clinical and laboratory studies have identified the benefits of an array of natural ingredients for skin care. Consequently, a number of these ingredients and compounds are today being developed, used or considered not only for anti-aging effects, but also for use in dermatologic disorders. Certain ingredients, such as colloidal oatmeal and aloe vera, have been identified as beneficial in the treatment of psoriasis and atopic dermatitis, respectively, due to their anti-inflammatory properties. For combating acne and rosacea, green tea, niacinamide and feverfew are considered efficacious. As to hyperpigmentation and antioxidative capabilities, licorice, green tea, arbutin, soy, acai berry, turmeric and pomegranate are among those plants and compounds found to be most beneficial. Additional research is needed to determine to confirm and elucidate the benefits of these ingredients in the prevention and management of skin disease.

  17. The role of nonfat ingredients on confectionery fat crystallization.

    West, Ryan; Rousseau, Dérick

    2017-03-31

    Confections such as chocolate and biscuit fillings are composed of a continuous fat phase that contains dispersed nonfat ingredients such as sugar and cocoa powder. Research on fat crystallization and rheology in confections often extrapolates crystallization and textural properties from bulk to mixed systems while overlooking the important role of composition or particle interactions. For example, in chocolate processing the fat phase aids dispersed phase lubrication and fluidity whereas the dispersed particles assist in fat crystallization by providing many nucleation sites. In confections with a high dispersed phase volume fraction, fat crystallization may be hindered due to reduced triacyglycerol mobility, confinement, and increased tortuosity. This is further complicated in systems with slow crystallizing fats such as palm oil whose crystallization is exceptionally sensitive to composition and processing. This review breaks down the physical chemistry of fat-based confections and discusses the impact of different nonfat ingredients towards fat crystallization and rheology. The behavior of palm oil is further highlighted as it is becoming increasingly popular as a confectionery ingredient. Lastly, ingredient-ingredient interactions and their role in fat crystallization are described along with force spectroscopy as a novel tool to characterize such phenomena. Force spectroscopy utilizes atomic force microscopy to measure intermolecular forces as a function of distance but remains largely unexplored in the area of food science.

  20. Electromagnetic Scattering from Vegetation Canopies.

    Science.gov (United States)

    Sarabandi, Kamal

    Satellite-borne imaging radar has been proposed by the remote sensing community as a potential sensor for the acquisition of quantitative information about forested area on a global scale. To achieve this goal, it is necessary to develop retrieved algorithms that can provide reasonable estimate of vegetation biomass, leaf moisture content, and other physical parameters of tree canopies from multifrequency/multipolarization observations of their radar backscattering coefficients. Retrieval algorithms often are called "inverse problem" because their input/output parameters are the inverse of those associated with the direct problem, which in the present case refers to the development of a radar scattering model that relates the radar response to the canopy architecture and associated parameters. This thesis provides electromagnetic solutions to several problems associated with scattering from tree canopies. The forest canopy is modelled in the form of layers comprised of randomly distributed particles with known statistical properties. In Chapters 2-8 effective scattering models for different constituent particles of vegetation canopies are developed by employing appropriate asymptotic solutions and approximations. The effects of various physical features of the particles, such as curvature and variation in thickness for planar leaves and roughness for tree trunks, on their scattering behavior are examined. In Chapter 9 the scattering problem of inhomogeneous layered media is formulated via the vector radiative transfer equations and a first-order solution for the radar scattering coefficients is obtained. The radiative transfer solution is formulated in terms of two sets of input functions: the scattering matrices of the constituent particles, which are given in Chapters 2-8, and the size and orientation distribution functions of the particles. The radar scattering model and associated input functions can be used to conduct sensitivity analyses to determine the

    Maintenance of normal blood glucose levels is important for avoiding chronic diseases such as type 2 diabetes, cardiovascular problems, and obesity. Type 2 diabetes is one of the major health problems affecting the world population and this condition can be exacerbated by poor diet, low physical activity, and genetic abnormalities. Food plays an important role in the management of blood glucose and associated complications in diabetes. This is attributed to the ability of food-based ingredients to modulate blood glucose without causing any adverse health consequences. This chapter focuses on four important food groups such as cereals, legumes, fruits, and spices that have active ingredients such as soluble dietary fiber, polyphenols, and antinutrients with the ability to reduce glycemic and insulin response in humans. Other food ingredients such as simple sugars, sugar alcohols, and some proteins are also discussed in moderation. Copyright © 2013 Elsevier Inc. All rights reserved.

    Published evidence on common ingredients of "energy drinks" and other dietary supplements widely used by consumers in hopes of enhancing athletic performance is reviewed. Preworkout products- unregulated dietary supplements- typically contain "proprietary blends" of multiple ingredients, including caffeine, dimethylamylamine, creatine, arginine, β-alanine, taurine, and phosphates. While some dietary supplement labels instruct consumers to seek the advice of a health care professional before using the products, the labels usually do not disclose all ingredients or their precise amounts, and evidence to support the purported performance-enhancing benefits is generally lacking. There is limited evidence to support the use of some preworkout supplement ingredients. For example, in one small placebo-controlled study (n = 12), the use of the energy drink Red Bull (containing caffeine and taurine) 40 minutes before a simulated cycling time trial appeared to provide a meaningful ergogenic benefit; in another small study (n = 12), the use of a similar caffeine-containing product (Redline) by strength-trained athletes was found to improve reaction time, energy, and mental focus relative to placebo use. However, published evidence on the use of the other ingredients listed above is scant, inconclusive, or conflicting. Adverse effects reported in association with preworkout supplements include gastrointestinal symptoms, cardiac arrhythmia, blood pressure increases, and potential effects on lipids and blood glucose. Although evidence exists to support the performance-enhancement efficacy of some preworkout ingredients as standalone agents, published data on combination products are scant, inconclusive, or conflicting. The safety of these products may be compromised if users consume larger-than-recommended amounts or use more than one product.

    Full Text Available Enzymes are the tools of choice in the on-going quest for non-pollutant processes to discover molecules for use in skin products. Amongst these biocatalysts, lipases offer considerable potential in terms of ingredient development and are of interest in skin dermocosmetic formulations possessing sensory or biological activities. Lipases have been studied for around thirty years and, in most cases, these enzymes function under what are deemed to be mild conditions, displaying remarkable efficacy particularly in terms of selectivity. This particularly effective strategy will be illustrated through typical synthesis, demonstrating how ester or amide active ingredients are obtained.

    2017-01-01

    In order to understand the status of Salmonella contamination of feed production chain in Karst rural areas, southwest of China, a total of 1077 feed samples including animal feed materials and feed products were randomly collected from different sectors of feed chain covering feed mills, farms, and feed sales in nine regions of Karst rural areas between 2009 and 2012, to conduct Salmonella test. The different positive rates with Salmonella contamination were detected, the highest was 4.7 % in 2009, the lowest was 0.66 % in 2011, while 4.3 % in 2010, 2.8 % in 2012, respectively. Twelve types of feed including concentrate, complete, self-made, and feed ingredients were inspected. Salmonella contamination mainly concentrated on animal protein material such as meat meal, meat and bone meal, feather meal, blood meal, and fish meal. No Salmonella contamination was detected in feed yeast, microbial protein, rapeseed, and soybean meal. Salmonella contamination existed in each sector of feed production chain. This investigation provided a basic reference for feed production management and quality control in feed production chain in Karst rural areas of China.

  8. RECONSTRUCTION OF EXISTING LIVESTOCK FEED PRODUCTION PLANTS BY ADDING A HYDRAULIC ADDER

    2007-06-01

    Full Text Available Recipes determine the quality of livestock feed and the hydraulic adders are one of the elements determining if the given recipe will be carried out. Generally, construction of existing adders does not allow accomplishment of that aim i.e. they do not meet recipe requirements. Consequently, researches which determined deviations in ingredient adding present with existing adders and with the experimental hydraulic adder were conducted. The research was conducted for two years (2005 and 2006 in two livestock feed factories in the Republic of Croatia on samples of feed mixtures for pigs weighing up to 15 and 25 kilos. Relative error was the means for comparison of weighing deviations between the hydraulic adder and the adders powered by means of an electric motor. Research results indicate that none of the two observed livestock feed production plants in 30 repetitions for two kinds of feed mixture showed a feed mixture weighing that would correspond to the specifications in the recipe. Additionally, hydraulic adders showed a greater precision in adding fish meal, extruded soybean and soybean meal when compared with the adders powered by means of an electric motor. However, the adders powered by means of an electric motor showed greater precision in adding corn. Based on the research results it can be concluded that using hydraulic adders instead of the adders powered by means of an electric motor will result in more accuracy in dosing ingredients with fine and middle granularity, whereas this can not be applied to dosing coarse grained ingredients.

  17. COMPANION ANIMALS SYMPOSIUM: Rendered ingredients significantly influence sustainability, quality, and safety of pet food.

    Science.gov (United States)

    Meeker, D L; Meisinger, J L

    2015-03-01

    The rendering industry collects and safely processes approximately 25 million t of animal byproducts each year in the United States. Rendering plants process a variety of raw materials from food animal production, principally offal from slaughterhouses, but include whole animals that die on farms or in transit and other materials such as bone, feathers, and blood. By recycling these byproducts into various protein, fat, and mineral products, including meat and bone meal, hydrolyzed feather meal, blood meal, and various types of animal fats and greases, the sustainability of food animal production is greatly enhanced. The rendering industry is conscious of its role in the prevention of disease and microbiological control and providing safe feed ingredients for livestock, poultry, aquaculture, and pets. The processing of otherwise low-value OM from the livestock production and meat processing industries through rendering drastically reduces the amount of waste. If not rendered, biological materials would be deposited in landfills, burned, buried, or inappropriately dumped with large amounts of carbon dioxide, ammonia, and other compounds polluting air and water. The majority of rendered protein products are used as animal feed. Rendered products are especially valuable to the livestock and pet food industries because of their high protein content, digestible AA levels (especially lysine), mineral availability (especially calcium and phosphorous), and relatively low cost in relation to their nutrient value. The use of these reclaimed and recycled materials in pet food is a much more sustainable model than using human food for pets.

    Kuang, S S; Oliveira, J C; Crean, A M

    2010-11-01

    Microencapsulation has been developed by the pharmaceutical industry as a means to control or modify the release of drug substances from drug delivery systems. In drug delivery systems microencapsulation is used to improve the bioavailability of drugs, control drug release kinetics, minimize drug side effects, and mask the bitter taste of drug substances. The application of microencapsulation has been extended to the food industry, typically for controlling the release of flavorings and the production of foods containing functional ingredients (e.g. probiotics and bioactive ingredients). Compared to the pharmaceutical industry, the food industry has lower profit margins and therefore the criteria in selecting a suitable microencapsulation technology are more stringent. The type of microcapsule (reservoir and matrix systems) produced and its resultant release properties are dependent on the microencapsulation technology, in addition to the physicochemical properties of the core and the shell materials. This review discusses the factors that affect the release of bioactive ingredients from microcapsules produced by different microencapsulation technologies. The key criteria in selecting a suitable microencapsulation technology are also discussed. Two of the most common physical microencapsulation technologies used in pharmaceutical processing, fluidized-bed coating, and extrusion-spheronization are explained to highlight how they might be adapted to the microencapsulation of functional bioactive ingredients in the food industry.

    Food service and retail sectors offer consumers a variety of mixed ingredient salads that contain fresh-cut vegetables and other ingredients such as fruits, nuts, cereals, dairy products, cooked seafood, cooked meat, cured meats, or dairy products obtained from external suppliers. Little is known about the behavior of enteric bacterial pathogens in mixed ingredient salads. A model system was developed to examine the fate of Salmonella enterica (inoculum consisting of S. enterica serovars Agona, Typhimurium, Enteritidis, Brandenberg, and Kentucky) on the surface of romaine lettuce tissues incubated alone and in direct contact with Cheddar cheese or cooked chicken. S. enterica survived but did not grow on lettuce tissues incubated alone or in contact with Cheddar cheese for 6 days at either 6 or 14°C. In contrast, populations increased from 2.01 ± 0.22 to 9.26 ± 0.22 CFU/cm(2) when lettuce washed in water was incubated in contact with cooked chicken at 14°C. Populations on lettuce leaves were reduced to 1.28 ± 0.14 CFU/cm(2) by washing with a chlorine solution (70 ppm of free chlorine) but increased to 8.45 ± 0.22 CFU/cm(2) after 6 days at 14°C. Experimentation with a commercial product in which one third of the fresh-cut romaine lettuce was replaced with inoculated lettuce revealed that S. enterica populations increased by 4 log CFU/g during storage for 3 days at 14°C. These findings indicate that rapid growth of bacterial enteric pathogens may occur in mixed ingredient salads; therefore, strict temperature control during the manufacture, distribution, handling, and storage of these products is critical.

    Full Text Available Background. Baby-led feeding exists in the practice of pediatrics since 2002. But there are still no clear results on the effectiveness of its implementation and the impact on the health of young children. Particular attention is required to study the effectiveness of introducing complementary feeding. Materials and methods. We analyzed 245 questionnaires of infants with baby-led-feeding. In the questionnaires for mothers, questions were raised about the initiation of the introduction of complementary feeding, its types, the child’s reaction, with the assessment of physical development and the previous diseases. Results. Children with baby-led-feeding have a tendency to late introduction of complementary feeding (from 6 months. It turned out that until this age, the child receives only breast milk, which can’t satisfy the need for important constituent ingredients. They are necessary for the child at this age, and it leads to various metabolic disorders in the form of allergic di­seases, metabolic syndrome, anemia, osteoporosis and others. Particular concern was caused by the fact that children start receiving meat products too late, which naturally leads to the development of iron deficiency anemia. In addition, contrary to the current norms and regulations, we noticed frequent facts of self-consumption of the whole milk itself and fermented milk products made from it (kephir, yoghurt. Conclusions. Based on the study of this question, it was proved that the existing provisions on the introduction of complementary foods with baby-led-feeding require supervision and correction in accordance with the state of children’s health and the existing provisions of the World Health Organization.

    Full Text Available Solution of the problem of alimentation structure improvement is related to creation of functional foodstuff with a balanced content of the major nutrient materials enriched in missing micronutrients and, at the same time, being daily products. Multicomponent structure of vegetable oils provides ample opportunities for developing of products preventing deficiency in essential fatty acids, vitamins andother physiologically functional ingredients. Grape-seed oil is of high bioavailability determined by a complex of biologically active substances, bioflavanoids, a group of vitamins, being the most important of them. Physiological effect of grape-seed oil includes anti-cholesterol property preventing cardio-vascular diseases.The thesis covers studies of vegetable oil mixtures made on the basis of sunflower and grape-seed oils. The study covers oxidative stability of vegetable oil mixture, based on determination of intensity of primary and secondary oxidation products formation.

    Vegetable oils and fats make up a significant part of the energy intake in typical European diets. However, their use as ingredients in a diverse range of different foods means that their consumption is often hidden, especially when oils and fats are used for cooking. As a result, there are no reliable estimates of the consumption of different vegetable oils and fats in the diet of European consumers for use in, for example, nutritional assessments or chemical risk assessments. We have developed an innovative model to estimate the consumption of vegetable oils and fats by European Union consumers using the European Union consumption databases and elements of probabilistic modelling. A key feature of the approach is the assessment of uncertainty in the modelling assumptions that can be used to build user confidence and to guide future development.

  15. ANALYSIS OF ANIMAL- AND PLANT-DERIVED FEED ...

    Science.gov (United States)

    During a national survey of polychlorinated dibenzo-p-dioxins (CDD), dibenzofurans (CDF), and dioxin-like coplanar PCBs (PCB) in poultry, elevated concentrations above 20 parts per trillion (ppt) toxic equivalents (TEQ) were found in the fat of 2 broilers. These TEQ values were driven by very high concentrations of CDD. A team comprised of individuals from the United States (US) Environmental Protection Agency (EPA), the US Food and Drug Administration (FDA), and the US Department of Agriculture (DA) traced the source of elevated CDD to a minor component in the poultry feed. This component was ball clay and it was used as an anti-caking agent in the soybean meal. The ball clay often comprised less than 0.2% of the dry weight of the complete ration in contaminated poultry. The investigation traced the ball clay to a mine in Mississippi. After learning that other ball clay mines in Kentucky and Tennessee also contained elevated CDD levels, the FDA issued a letter to producers or users of clay products in animal feeds asking that they cease using ball clay in any animal feed or feed ingredient. Subsequent contaminations of animal feed in Belgium with PCB and of citrus pulp from Brazil with CDD and CDF alerted countries worldwide that animal feeds can become contaminated with CDD/CDF/PCB (DFP) via contamination of minor feed components. This type of contamination can overshadow the normal air-to-leaf process that is thought to dominate the food chain for terr

    This review explores the possibilities to determine livestock consumption of genetically modified (GM) feeds/ingredients including detection of genetically modified organism (GMO)-related DNA or proteins in animal samples, and the documentary system that is in place for GM feeds under EU legislation. The presence and level of GMO-related DNA and proteins can generally be readily measured in feeds, using established analytical methods such as polymerase chain reaction and immuno-assays, respectively. Various technical challenges remain, such as the simultaneous detection of multiple GMOs and the identification of unauthorized GMOs for which incomplete data on the inserted DNA may exist. Given that transfer of specific GMO-related DNA or protein from consumed feed to the animal had seldom been observed, this cannot serve as an indicator of the individual animal's prior exposure to GM feeds. To explore whether common practices, information exchange and the specific GM feed traceability system in the EU would allow to record GM feed consumption, the dairy chain in Catalonia, where GM maize is widely grown, was taken as an example. It was thus found that this system would neither enable determination of an animal's consumption of specific GM crops, nor would it allow for quantitation of the exposure.

    Pinotti, L.

    2011-01-01

    Full Text Available A number of issues have weakened the public's confidence in the quality and wholesomeness of foods of animal origin. As a result farmers, nutritionists, industry and governments have been forced to pay serious attention to animal feedstuff production processes, thereby acknowledging that animal feed safety is an essential prerequisite for human food safety. Concerns about these issues have produced a number of important effects including the ban on the use of processed animal proteins, the ban on the addition of most antimicrobials to farm animals diets for growth‐promotion purposes, and the implementation of feed contaminant regulations in the EU. In this context it is essential to integrate knowledge on feed safety and feed supply. Consequently, purchase of new and more economic sources of energy and protein in animal diets, which is expected to conform to adequate quality, traceability, environmental sustainability and safety standards, is an emerging issue in livestock production system.

    Multivitamin/mineral products (MVMs) are the dietary supplements most commonly used by US adults. During manufacturing, some ingredients are added in amounts exceeding the label claims to compensate for expected losses during the shelf life. Establishing the health benefits and harms of MVMs requires accurate estimates of nutrient intake from MVMs based on measures of actual rather than labeled ingredient amounts. Our goals were to determine relations between analytically measured and labeled ingredient content and to compare adult MVM composition with Recommended Dietary Allowances (RDAs) and Tolerable Upper Intake Levels. Adult MVMs were purchased while following a national sampling plan and chemically analyzed for vitamin and mineral content with certified reference materials in qualified laboratories. For each ingredient, predicted mean percentage differences between analytically obtained and labeled amounts were calculated with the use of regression equations. For 12 of 18 nutrients, most products had labeled amounts at or above RDAs. The mean measured content of all ingredients (except thiamin) exceeded labeled amounts (overages). Predicted mean percentage differences exceeded labeled amounts by 1.5-13% for copper, manganese, magnesium, niacin, phosphorus, potassium, folic acid, riboflavin, and vitamins B-12, C, and E, and by ∼25% for selenium and iodine, regardless of labeled amount. In contrast, thiamin, vitamin B-6, calcium, iron, and zinc had linear or quadratic relations between the labeled and percentage differences, with ranges from -6.5% to 8.6%, -3.5% to 21%, 7.1% to 29.3%, -0.5% to 16.4%, and -1.9% to 8.1%, respectively. Analytically adjusted ingredient amounts are linked to adult MVMs reported in the NHANES 2003-2008 via the Dietary Supplement Ingredient Database (http://dsid.usda.nih.gov) to facilitate more accurate intake quantification. Vitamin and mineral overages were measured in adult MVMs, most of which already meet RDAs. Therefore

    Full Text Available Aim: This study was carried out to evaluate groundnut haulms (GNH as alternate feed source by its incorporation and assessment in terms of feed intake and growth performance in the diets of broilers. Materials and Methods: A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates (n=60. Experimental Birds in group T1 were fed with conventional feed while birds in T2, T3, T4 were fed containing 2%, 4%, and 6% of GNH replacing maize and soyabean on iso-nitrogenous basis. Results: Feed intake increases significantly (p>0.05 with increasing level of GNH in the diets of experimental birds. Highest feed intake was recorded in T4 (6% GNH, followed by T3 (4% GNH than T2 (2% GNH and T1 (control. Birds fed GNH gained significantly (p<0.05 higher body weight than birds fed the control diet. Birds in T4 [6% GNH] gained highest body weight, followed by T3 (4% GNH than T2 (2% GNH and T1 (control. However, feed conversion ratio (FCR remained non-significant for all treatment groups. Conclusion: On the basis of the results of this study, it is concluded that supplementation of GNH can successfully replace costly ingredients like maize and soybean meal in the diets of broiler birds up to the level of 6 percent of concentrate mixture without any harmful effects on feed intake, growth and FCR.

    ABSTRACT Contamination of pet food with Salmonella is a serious public health concern, and several disease outbreaks have recently occurred due to human exposure to Salmonella tainted pet food. The problem is especially challenging for raw pet foods (which include raw meats, seafood, fruits, and vegetables). These foods are becoming increasingly popular because of their nutritional qualities, but they are also more difficult to maintain Salmonella-free because they lack heat-treatment. Among various methods examined to improve the safety of pet foods (including raw pet food), one intriguing approach is to use bacteriophages to specifically kill Salmonella serotypes. At least 2 phage preparations (SalmoFresh® and Salmonelex™) targeting Salmonella are already FDA cleared for commercial applications to improve the safety of human foods. However, similar preparations are not yet available for pet food applications. Here, we report the results of evaluating one such preparation (SalmoLyse®) in reducing Salmonella levels in various raw pet food ingredients (chicken, tuna, turkey, cantaloupe, and lettuce). Application of SalmoLyse® in low (ca. 2–4×106 PFU/g) and standard (ca. 9×106 PFU/g) concentrations significantly (P Salmonella contamination in all raw foods examined compared to control treatments. When SalmoLyse®-treated (ca. 2×107 PFU/g) dry pet food was fed to cats and dogs, it did not trigger any deleterious side effects in the pets. Our data suggest that the bacteriophage cocktail lytic for Salmonella can significantly and safely reduce Salmonella contamination in various raw pet food ingredients. PMID:27738557

  2. Review article: health benefits of some physiologically active ingredients and their suitability as yoghurt fortifiers.

    The article is concerned with health benefits of two main physiologically active ingredients namely, Isoflavones and γ-Aminobutyric acid, with emphasis on their fitness for fortification of yoghurt to be consumed as a functional food. Isoflavones (ISO) are part of the diphenol compounds, called "phytoestrogens," which are structurally and functionally similar to estradiol, the human estrogen, but much less potent. Because of this similarity, ISO were suggested to have preventive effects for many kinds of hormone-dependent diseases. In nature, ISO usually occur as glycosides and, once deconjugated by the intestinal microflora, the ISO can be absorbed into the blood. At present, it seems convincing their possible protective actions against various cancers, osteoporosis and menopausal symptoms and high levels of blood cholesterol as well as the epidemiological evidence. Γ-Aminobutyric acid (GABA), it is an amino acid that has long been reported to lower blood pressure by intravenous administration in experimental animals and in human subjects. GABA is present in many vegetables and fruits but not in dairy products. GABA was reported to lower blood pressure in people with mild hypertension. It was suggested that low-dose oral GABA has a hypotensive effect in spontaneously hypertensive. Yoghurt beyond its ability to be probiotic food via its culturing with the gut strains, it could further carry more healthy benefits when it was fortified with physiological active ingredients, especially GABA versus ISO preferring, whether, bacteriologically or biochemically, a fortification level of 50 mg ISO/kg or 200 mg GABA/kg.

    The quality of chicken meat, which is one of the most widely consumed meats in the world, has been the subject of research and studies for many years. There are several ways to improve the quality of this type of meat, including changing the concentrations of individual molecular components. Such important components of meat are inter alia, cholesterol, vitamin E, and some fatty acids such as ω-3 and ω-6. Manipulation of ingredient levels may be achieved by enriching chicken feed with elements of different types such as vegetable oils, garlic, or selenium. Thus far, various biochemical and biophysical methods have been used to study quality of different meat types, especially broiler meat. Here, the authors demonstrate the use of high-resolution time-of-flight secondary ion mass spectrometry (TOF-SIMS) mass spectrometry to assess how variations in animal nutrition affect concentrations of specific lipids in the meat, such as cholesterol and vitamin E. In the presented experiment, there were four different dietary treatments. Feed for animals in the first group was supplemented with soy oil in 50%, the second group's feed was supplemented with linseed oil in 50%, a combination of these two oils in the proportion of 44%:56% was used for the third group, and in the reference group, animals were fed with beef tallow. From each group, four individuals were selected for further analysis. Positive and negative ion mass spectra were generated from the pectoralis superficialis muscle tissue of the left carcass side of each one animal. Using TOF-SIMS with a bismuth cluster ion source (Bi3 (+)), and based on characteristic peaks for cholesterol in the positive mode and vitamin E in the negative mode, the authors have illustrated the relationship of these lipids levels to the various feeding regimens. Simultaneously, the authors characterized the varying dependences on the concentrations of measured lipids in fat and muscle fibers. The cholesterol concentration in muscle

    Salmonella control in animal feed is important in order to protect animal and public health. Organic acids is one of the control measures used for treatment of Salmonella contaminated feed or feed ingredients. In the present study, the efficacy of formic acid (FA) and different blends of FA, propionic acid (PA) and sodium formate (SF) was investigated. Four Salmonella strains isolated from feed were assayed for their acid tolerance. Also, the effect of lower temperatures (5°C and 15°C) compared to room temperature was investigated in rape seed and soybean meal. The efficacy of acid treatments varied significantly between different feed materials. The strongest reduction was seen in pelleted and compound mash feed (2.5 log10 reduction) followed by rapeseed meal (1 log10 reduction) after 5 days exposure. However, in soybean meal the acid effects were limited (less than 0.5 log10 reduction) even after several weeks' exposure. In all experiments the survival curves showed a concave shape, with a fast initial death phase followed by reduction at a slower rate during the remaining time of the experiment.No difference in Salmonella reduction was observed between FA and a blend of FA and PA, whereas a commercial blend of FA and SF (Amasil) was slightly more efficacious (0.5-1 log10 reduction) than a blend of FA and PA (Luprocid) in compound mash feed. The Salmonella Infantis strain was found to be the most acid tolerant strain followed by, S. Putten, S. Senftenberg and S. Typhimurium. The tolerance of the S. Infantis strain compared with the S. Typhimurium strain was statistically significant (pSalmonella in feed is a matter of reducing the number of viable bacterial cells rather than eliminating the organism. Recommendations on the use of acids for controlling Salmonella in feed should take into account the relative efficacy of acid treatment in different feed materials, the variation in acid tolerance between different Salmonella strains, and the treatment temperature.

    Vegetation dynamics are driven by climate, and at the same time they play a key role in forcing the different bio-geochemical cycles. As climate change leads to an increase in frequency and intensity of hydro-meteorological extremes, vegetation is expected to respond to these changes, and subsequently feed back on their occurrence. This response can be analysed using time series of different vegetation diagnostics observed from space, in the optical (e.g. Normalised Difference Vegetation Index (NDVI), Solar Induced Fluorescence (SIF)) and microwave (Vegetation Optical Depth (VOD)) domains. In this contribution, we compare the climatic drivers of different vegetation diagnostics, based on a monthly global data-cube of 24 years at a 0.25° resolution. To do so, we calculate the wavelet coherence between each vegetation-related observation and observations of air temperature, precipitation and incoming radiation. The use of wavelet coherence allows unveiling the scale-by-scale response and sensitivity of the diverse vegetation indices to their climatic drivers. Our preliminary results show that the wavelet-based statistics prove to be a suitable tool for extracting information from different vegetation indices. Going beyond traditional methods based on linear correlations, the application of wavelet coherence provides information about: (a) the specific periods at which the correspondence between climate and vegetation dynamics is larger, (b) the frequencies at which this correspondence occurs (e.g. monthly or seasonal scales), and (c) the time lag in the response of vegetation to their climate drivers, and vice versa. As expected, areas of high rainfall volumes are characterised by a strong control of radiation and temperature over vegetation. Furthermore, precipitation is the most important driver of vegetation variability over short terms in most regions of the world - which can be explained by the rapid response of leaf development towards available water content

    Full Text Available The aim of this research was to evaluate the quality of vegetable waste silages, using rice bran, onggok (cassava flour waste and pollard as carbohydrate sources. Vegetable waste was collected from local traditional market, consisted of corn husk, chinese cabbage and cabbage. Research was held in randomized block design consisted of six treatments with 3 replications. Treatments were (T1 vegetable waste + rice bran, (T2 vegetable waste + rice bran + rice straw, (T3 vegetable waste + onggok, (T4 vegetable waste + onggok + rice straw, (T5 vegetable waste + pollard, (T6 vegetable waste + pollard + rice straw. Lactobacillus plantarum 1A-2 was used as innoculant. The quality of silages was evaluated by measuring pH, temperature, population of lactic acid bacteria and lactic acid production. Nutrient characteristic was determined by proximate and fiber analysis. Results showed that pH of silages were not affected by treatments, but silage treated with rice bran, with or without rice straw addition, had higher temperature compared with others (29 oC or 28.3 oC. The highest population of lactic acid bacteria (1.65 x 109 cfu/g was found in silage using rice straw and onggok (T4, but the highest lactic acid production (0.41% was measured in silage using rice straw and rice bran (T2. In general, the use of rice bran as carbohydrate sources gave the highest lactic acid production followed by pollard and onggok. Different carbohydrate source gave different nutrients characteristic. Although the result was not significantly different, silage with highest protein content was measured in silage with pollard as carbohydrate source, followed with rice bran and onggok. The result showed that all carbohydrate sources used in this experiment can be used as silage ingredient resulting in good vegetable waste silage.

    Phenolic compounds in spices were reportedly found to possess high antioxidant capacities (AOCs), which may prevent or reduce risk of human diseases such as cardiovascular disease, cancer and diabetes. The potential AOC of Chinese five-spice powder (consist of Szechuan pepper, fennel seed, cinnamon, star anise and clove) with varying proportion of individual spice ingredients was investigated through four standard methods. Our results suggest that clove is the major contributor to the AOC of the five-spice powder whereas the other four ingredients contribute to the flavour. For example, the total phenolic content as well as ferric reducing antioxidant power (FRAP), Trolox equivalent antioxidant capacity (TEAC) and oxygen radical absorbance capacity (ORAC) values increased linearly with the clove percentage in five-spice powder. This observation opens the door to use clove in other spice mixtures to increase their AOC and flavour. Moreover, linear relationships were also observed between AOC and the total phenolic content of the 32 tested spice samples.

    Human skin is constantly exposed to damaging ultraviolet radiation (UVR), which induces a number of acute and chronic disorders. To reduce the risk of UV-induced skin injury, people apply an additional external protection in the form of cosmetic products containing sunscreens. Nowadays, because of the use of some chemical filters raises a lot of controversies, research focuses on exploring novel, fully safe and highly efficient natural UV-absorbing compounds that could be used as active ingredients in sun care products. A promising alternative is the application of multifunctional mycosporine-like amino acids (MAAs), which can effectively compete with commercially available filters. Here, we outline a complete characterization of these compounds and discuss their enormous biotechnological potential with special emphasis on their use as sunscreens, activators of cells proliferation, anti-cancer agents, anti-photoaging molecules, stimulators of skin renewal, and functional ingredients of UV-protective biomaterials.

    Many nutritional experts and food scientists are interested in developing functional foods containing bioactive agents and many of these health-promoting ingredients may benefit from nano/micro-encapsulation technology. Encapsulation has been proven useful to improve the physical and the chemical stability of bioactive agents, as well as their bioavailability and efficacy, enabling their incorporation into a wide range of formulations aimed to functional food production. There are several reviews concerning nano/micro-encapsulation techniques, but none are focused on the incorporation of the bioactive agents into food matrices. The aim of this paper was to investigate the development of microencapsulated food, taking into account the different bioactive ingredients, the variety of processes, techniques and coating materials that can be used for this purpose.

    Dietary fiber (DF) is one of the main dietary factors contributing to consumers' well-being. In this work the possibility of using the roasted coffee silverskin (CS), a byproduct of roasted coffee beans, as a DF-rich ingredient has been evaluated. The results of our investigation showed that this material has 60% total DF, with a relevant component (14%) of soluble DF. Although a small amount of free phenol compounds is present in CS, it has a marked antioxidative activity, which can be attributed to the huge amount of Maillard reaction products, the melanoidins. Static batch culture fermentation experiments showed that CS induces preferential growth of bifidobacteria rather than clostridia and Bacteroides spp. CS can be proposed as a new potential functional ingredient in consideration of the high content of soluble DF, the marked antioxidant activity, and the potential prebiotic activity.

    The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of 13 Panax spp root-derived ingredients as used in cosmetics. Panax "spp" indicates that multiple species within the genus are used in cosmetics, but not all species within that genus. Four species are being considered in this safety assessment. These ingredients function mostly as skin-conditioning agents-miscellaneous, fragrance ingredients, skin-conditioning agents-humectant, skin-conditioning agents-emollient, and cosmetic astringents. The Panel reviewed available data related to these ingredients and addressed the issue of pulegone, a constituent of these ingredients and other ingredients, such as peppermint oil. The Panel concluded that these Panax spp root-derived ingredients are safe in the practices of use and concentration as given in this safety assessment. © The Author(s) 2015.

    The cosmetics market has rapidly increased over the last years. For example, in 2011 it reached 242.8 billion US dollars, which was a 3.9% increase compared to 2010. There have been many recent trials aimed at finding the functional ingredients for new cosmetics. Gallic acid is a phytochemical derived from various herbs, and has anti-fungal, anti-viral, and antioxidant properties. Although phytochemicals are useful as cosmetic ingredients, they have a number of drawbacks, such as thermal stability, residence time in the skin, and permeability through the dermal layer. To overcome these problems, we considered conjugation of gallic acid with a peptide. We synthesized galloyl-RGD, which represents a conjugate of gallic acid and the peptide RGD, purified it by HPLC and characterized by MALDI-TOF with the aim of using it as a new cosmetic ingredient. Thermal stability of galloyl-RGD was tested at alternating temperatures (consecutive 4°C, 20°C, or 40°C for 8 h each) on days 2, 21, 41, and 61. Galloyl-RGD was relatively safe to HaCaT keratinocytes, as their viability after 48 h incubation with 500 ppm galloyl-RGD was 93.53%. In the group treated with 50 ppm galloyl-RGD, 85.0% of free radicals were removed, whereas 1000 ppm galloyl-RGD suppressed not only L-DOPA formation (43.8%) but also L-DOPA oxidation (54.4%). Galloyl-RGD is a promising candidate for a cosmetic ingredient.

    Full Text Available Objective: Where swallowing difficulties are chronic or progressive, or a patient is palliative, tube feeding is often not deemed appropriate. Instead, patients continue to eat and drink despite the risks of pneumonia and death. There is currently little evidence to guide clinical practice in this field often termed “risk feeding.” This qualitative study investigated staff, patient, and family member perceptions of risk feeding practices in one New Zealand hospital. Method: Twenty-nine staff members and six patients and/or their family were interviewed. Results: Thematic analysis revealed four global themes: supporting practice, communication, complexity of feeding decisions, and patient and family-centered care. Staff described limited education and organizational policy around risk feeding decisions. Communication was considered a major factor in the success. Conclusion: Feeding decisions are complex in the hospital environment. The themes identified in this study provide a foundation for hospital guideline development and implementation.

    Functional ingredients can be encapsulated by various wall materials for controlled release in food and digestion systems. Starch, as one of the most abundant natural carbohydrate polymers, is non-allergenic, GRAS, and cheap. There has been increasing interest of using starch in native and modified forms to encapsulate food ingredients such as flavours, lipids, polyphenols, carotenoids, vitamins, enzymes, and probiotics. Starches from various botanical sources in granular or amorphous forms are modified by chemical, physical, and/or enzymatic means to obtain the desired properties for targeted encapsulation. Other wall materials are also employed in combination with starch to facilitate some types of encapsulation. Various methods of crafting the starch-based encapsulation such as electrospinning, spray drying, antisolvent, amylose inclusion complexation, and nano-emulsification are introduced in this mini-review. The physicochemical and structural properties of the particles are described. The encapsulation systems can positively influence the controlled release of food ingredients in food and nutritional applications. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Rosacea is a chronic inflammatory skin condition characterized by cutaneous hypersensitivity. There are many therapeutic options available for the treatment of rosacea, but none are curative. Since the pathogenesis of rosacea remains elusive, it is not surprising that no single treatment is paramount and that many patients find therapies unsatisfactory or even exacerbating. Treatments are prescribed to work in concert with each other in order to ameliorate the common clinical manifestations, which include: papules and pustules, telangiectasias, erythema, gland hypertrophy, and ocular disease. The most validated topical therapies include metronidazole, azelaic acid, and sodium sulfacetamide-sulfur. Many other topical therapies, such as calcineurin inhibitors, benzoyl peroxide, clindamycin, retinoids, topical corticosteroids, and permethrin have demonstrated varying degrees of success. Due to the inconsistent results of the aforementioned therapies patients are increasingly turning to alternative products containing natural ingredients or botanicals to ease inflammation and remit disease. Additional research is needed to elucidate the benefits of these ingredients in the management of rosacea, but some important considerations regarding the natural ingredients with clinical data will be discussed here.

  9. Safety Evaluation of Cosmetic Ingredients Regarding Their Skin Sensitization Potential

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Up to today, product safety evaluation in the EU is predominantly based on data/information on their individual ingredients. Consequently, the quality and reliability of individual ingredient data is of vital interest. In this context, the knowledge about skin sensitization potential is an explicit need for both hazard and risk assessment. Proper skin sensitization data of the individual chemicals is essential, especially when dermal contact is intended, like for cosmetics. In some cases, e.g., in the presence of irritating chemicals, the combination of individual ingredients may also need to be evaluated to cover possible mixture effects. Today, it seems unlikely or even impossible that skin sensitization in humans can be adequately described by a single test result or even by a simple combination of a few data points (in vivo or in vitro. It is becoming evident that a set of data (including human data and market data and knowledge about the ingredient’s specific sensitizing potency needs to be taken into account to enable a reliable assessment of skin sensitization. A more in-depth understanding on mechanistic details of the Adverse-Outcome-Pathway of skin sensitization could contribute key data for a robust conclusion on skin sensitization.

    Full Text Available Defatted microalgal biomass derived from biorefinery can be potential feed ingredients for carnivorous fish. The present study investigated the growth, feed intake:gain and health parameters in Atlantic salmon fed for 84 days with defatted Nannochloropsis oceania as a fishmeal replacer. Fish fed feeds containing the algal biomass (at 10 and 20% inclusion, alga groups were compared with groups that consumed alga-devoid feeds (control group. The fish that received 20% alga tended to have reduced weight gain and specific growth rate. Condition factor, feed conversion ratio and feed intake of this fish group were significantly different when compared with the control group. Hepatosomatic and viscerosomatic indices, whole body and fillet proximate composition were not affected by the dietary treatments. Digestibility of dry matter, protein, lipid, ash and energy, as well as retention of lipid and energy of the fish that received feed with 20% alga meal were also significantly different from those of the control group. Serum superoxide dismutase activity of the 10% alga-fed fish was significantly higher compared with the control fish. Although alga feeding did not cause any distal intestinal inflammation, the intestinal proteins that were altered upon feeding 20% algal meal might be pointing to systemic physiological disturbances. In conclusion, feeds with 20% alga had a negative effect on feed intake, FCR, lipid and energy retention and health of the fish. The defatted Nannochloropsis oceania can be used at modest inclusion levels, around 10%, without negative effects on the performance of Atlantic salmon.

    There are more than 36,000 species of Cerambycidae recognized throughout the world (see Chapter 1), occurring on all continents except Antarctica (Linsley 1959). Given such numbers, it is not surprising that cerambycids display great diversity in their feeding habits. Both adults and larvae are almost exclusively phytophagous. Some adults appear not to feed at all,...

    Much research on animal feed has focused on finding alternative feed ingredients that can replace conventional ones (e.g., grains and beans) to reduce feed costs. The objective of this study was to evaluate the economic, as well as nutritional value of spent coffee grounds (SCG) and Japanese mugwort (Artemisia princeps) residues (APR) as alternative feed ingredients for ruminants. We also investigated whether pre-fermentation using Lactobacillus spp. was a feasible way to increase the feed value of these by-products. Chemical analyses and an in vitro study were conducted for SCG, APR, and their pre-fermented forms. All the experimental diets for in vitro ruminal fermentation were formulated to contain a similar composition of crude protein, neutral detergent fiber and total digestible nutrients at 1x maintenance feed intake based on the dairy National Research Council (NRC). The control diet was composed of ryegrass, corn, soybean meal, whereas the treatments consisted of SCG, SCG fermented with Lactobacillus spp. (FSCG), APR, and its fermented form (FAPR). The treatment diets replaced 100 g/kg dry matter (DM) of the feed ingredients in the control. Costs were lower for the all treatments, except FAPR, than that of the control. After 24-h incubation, the NDF digestibility of the diets containing SCG and its fermented form were significantly lower than those of the other diets (P Korean Won (KRW). Diets supplemented with SCG or FSCG tended to have a higher total volatile fatty acid (VFA) concentration, expressed as per KRW, compared with the control (P = 0.06). Conversely, the fermentation process of SCG and APR significantly decreased total gas production and VFA production as expressed per KRW (P < 0.05). Because of their nutrient composition and relatively lower cost, we concluded that SCG and APR could be used as alternative feed sources, replacing conventional feed ingredients. However, pre-fermentation of agricultural by-products, such as SCG and APR, may be

    The purposes of this study were (1) to analyze and categorize certified organic Wisconsin dairy farms based on general farm characteristics and feeding strategies during the course of 2010, and (2) to evaluate herd milk production and income over feed costs (IOFC). An on-site survey containing sections on farm demographics, feeding, grazing, and economics was conducted on 69 farms (12.6% survey response rate). A nonhierarchical clustering method using 9 variables related to general farm characteristics, feed supplementation, and grazing was applied to partition the farms into clusters. A scree plot was used to determine the most appropriate number of clusters. Dry matter intake was approximated based on farmer-reported total amounts of feed consumed (feed offered less refusals). Milk production was evaluated using reported milk rolling herd averages (RHA). Income over feed costs was calculated as milk sales minus feed expenses. The farms in clusters 1 (n=8) and 3 (n=32), the large and small high-input farms, respectively, included more feed ingredients in their lactating cow diets and relied more heavily on concentrates than farms in other clusters. Cows on these farms were predominantly Holstein. Clusters 1 and 3 had the highest RHA (6,878 and 7,457 kg/cow per year, respectively) and IOFC ($10.17 and $8.59/lactating cow per day, respectively). The farms in cluster 2 (n=5) were completely seasonal, extremely low-input farms that relied much more heavily on pasture as a source of feed, with 4 out of the 5 farms having all of their operated land in pasture. Farms in cluster 2 relied on fewer feeds during both the grazing and nongrazing seasons compared with farms in the other clusters. These farms had the lowest RHA and IOFC at 3,632 kg/cow per year and $5.76/lactating cow per day, respectively. Cluster 4 (n=24), the partly seasonal, moderate-input, pasture-based cluster, ranked third for RHA and IOFC (5,417 kg/cow per year and $5.92/lactating cow per day

    To describe adherence with infant feeding and complementary feeding guidelines. Prospective study of infant feeding and complementary feeding practices were collected as part of the Cork BASELINE Birth Cohort Study. Cork, Ireland. Data are described for the 823 infants for whom a diary was completed. Breast-feeding was initiated in 81 % of infants, and 34 %, 14 % and 1 % of infants were exclusively breast-fed at hospital discharge, 2 and 6 months, respectively. Stage one infant formula decreased from 71 % at 2 months to 13 % at 12 months. The majority of infants (79 %) were introduced to solids between 17 and 26 weeks and 18 % were given solid foods before 17 weeks. Mothers of infants who commenced complementary feeding prior to 17 weeks were younger (29·8 v. 31·5 years; Pfood was usually baby rice (69 %), infant breakfast cereals (14 %) or fruit/vegetables (14 %). Meals were generally home-made (49 %), cereal-based (35 %), manufactured (10 %), dairy (3 %) and dessert-based (3 %). The median gap between the first-second, second-third, third-fourth and fourth-fifth new foods was 4, 2, 2 and 2 d, respectively. We present the largest prospective cohort study to date on early infant feeding in Ireland. The rate of breast-feeding is low by international norms. Most mothers introduce complementary foods between 4 and 6 months with lengthy gaps between each new food/food product. There is a high prevalence of exposure to infant breakfast cereals, which are composite foods, among the first foods introduced.

    Large amounts of waste are generated by the minimally processed vegetables industry, such as those from beetroot processing. The aim of this study was to determine the best method to obtain flour from minimally processed beetroot waste dried at different temperatures, besides producing a colorant from such waste and assessing its stability along 45 days. Beetroot waste dried at 70 °C originates flour with significant antioxidant activity and higher betalain content than flour produced from waste dried at 60 and 80 °C, while chlorination had no impact on the process since microbiological results were consistent for its application. The colorant obtained from beetroot waste showed color stability for 20 days and potential antioxidant activity over the analysis period, thus it can be used as a functional additive to improve nutritional characteristics and appearance of food products. These results are promising since minimally processed beetroot waste can be used as an alternative source of natural and functional ingredients with high antioxidant activity and betalain content.

    Turmeric, a rhizome of Curcumin longa L. is widely used as both a spice and an herbal medicine. The traditional use of turmeric in gastroenterology is mainly based on its choleretic activity. The aim of this study is to determine the effects of turmeric on bile flow (BF) and total bile acids (TBAs) excretion in a bile fistula rat model after acute duodenal administration. A significant dose-dependent enhancement in both BF and TBAs was detected after treatment with the turmeric decoctions which suggested the choleretic activity was bile acid-dependent secretion. In order to direct the active group of compounds, aqueous (AE), ethyl acetate (EtOAc), and petroleum ether (PE) extracts were investigated. The EtOAc and PE extracts showing high effects were purified to locate the active ingredients. Three curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) and 2 sesquiterpenes (bisacurone B and ar-turmerone) were isolated. It was found Bisacurone B was the most potent choleretic ingredient followed by ar-turmerone, bisdemethoxycurcumin demethoxycurcumin, and then curcumin. The amounts of the active ingredients were quantitatively analyzed by high-performance liquid chromatography. The EtOAc and PE extracts had high sesquiterpenes and curcuminoids content, while the AE extract had poor content of sesquiterpenes and curcuminoids which affected neither BF nor TBAs. Based on the results of multiple linear regression analysis, the content of BIS and TUR were dominant factors (P < 0.01) of controlling BL and TBAs in EtOAC and PE extracts. © 2016 Institute of Food Technologists®

Television programmes and newspaper articles that made reference to infant feeding during March 1999. UK mass media. Visual and verbal references to breast or bottle feeding in newspapers and television programmes. Overall, 235 references to infant feeding were identified in the television sample and 38 in the newspaper sample. Bottle feeding was shown more often than breast feeding and was presented as less problematic. Bottle feeding was associated with "ordinary" families whereas breast feeding was associated with middle class or celebrity women. The health risks of formula milk and the health benefits of breast feeding were rarely mentioned. The media rarely present positive information on breast feeding, even though this feeding practice is associated with the most health benefits. Health professionals and policy makers should be aware of patterns in media coverage and the cultural background within which women make decisions about infant feeding.

    This report summarizes initial studies into the chemical basis of the thermal insensitivity of INMX-104. The work follows upon similar efforts investigating this behavior for another DNAN-based insensitive explosive, IMX-101. The experiments described demonstrate a clear similarity between the ingredient interactions that were shown to lead to the thermal insensitivity observed in IMX-101 and those that are active in IMX-104 at elevated temperatures. Specifically, the onset of decomposition of RDX is shifted to a lower temperature based on the interaction of the RDX with liquid DNAN. This early onset of decomposition dissipates some stored energy that is then unavailable for a delayed, more violent release.

  15. Increasing the value of hominy feed as a coproduct by fermentation.

    Science.gov (United States)

    Sharma, Vivek; Moreau, Robert A; Singh, Vijay

    2008-05-01

    Hominy feed is a low value ($83.7/metric ton) coproduct of the corn dry milling process that accounts for nearly 35% of the starting corn quantity. The average composition of hominy feed on a dry basis is 56.9% starch, 25.2% neutral detergent fiber, 11.1% protein, and 5.3% fat. Starch in hominy feed can be fermented to ethanol thus increasing its levels of protein and fat. The increase in protein and fat percentages may increase the market competitiveness and price of hominy feed. Hydrolysis and fermentation were performed on nine hominy feed samples collected from three corn dry milling plants in the USA. The original hominy feed samples and postfermentation solids were analyzed for starch, protein, fat, and fiber content. Compared to the original hominy feed, the percentage increase in protein, fat and fiber in postfermentation solids of nine samples ranged from 10.4 to 21.3, 6.78 to 10.6, and 12.6 to 28.7% (dry basis), respectively. Ethanol yields varied from 271.7 to 380.2 l/metric ton for the nine hominy feed samples. These results indicate that the value of hominy feed as an animal feedstock can potentially be increased with fermentation and can produce more profit per metric ton than currently being derived by its sale as a low protein feed ingredient.

  16. Breast-feeding multiples.

    Flidel-Rimon, O; Shinwell, E S

    2002-06-01

    Human breast milk is the best nutrition for human infants. Its advantages over the milk of other species, such as cows, include both a reduced risk for infections, allergies and chronic diseases, together with the full nutritional requirements for growth and development. Breast-feeding is as important for multiples as for singletons. Despite the advantages, multiples receive less breast-feeding than singletons. Common reasons for not breast-feeding multiples include the fear of not fulfilling the infants' needs and the difficulty of coping with the demands on the mother's time. In addition, many multiples are delivered prematurely and by Caesarean section. Maternal pain and discomfort together with anxiety over the infants' condition are not conducive to successful breast-feeding. During lactation, the mother needs to add calories to her daily diet. It has been recommended to add approximately 500-600 kcal/day for each infant. Thus, between eating, nursing and sleeping, life is very busy for the mother of multiples. However, there is evidence that, with appropriate nutrition, one mother can nourish more than one infant. Also, simultaneous breast-feeding can save much time. Combined efforts of parents, close family, friends and the medical team can help to make either full or partial breast-feeding of multiples possible. However, when breast-feeding is not possible, health care workers need to carefully avoid judgmental approaches that may induce feelings of guilt.

Feeding and breeding in conventional production are emerged some of the negative effects and also it is more in organic production with new restrictions. Organic production is based on animal welfare. On the basis of behaviors such as feather-pecking and cannibalism known to be low in protein level of rations and unbalanced in terms of amino acids or minerals. As of 2015, organic poultry feed provided the appropriate conditions that will be 95% organic certified in Turkey and therefore, to create a balanced ration and feed hygiene in protecting brings serious challenges. Fodder supply of organic poultry feed raw materials that make up the quality, quantity and issue forms a significant effect on the health of the poultry additives permitted. The quality of the feed raw materials that constituent diets, quantity, feed supplying form and permitted feed additives significantly affects the health of poultry. Different physiological stages of the animal's nutritional requirements in order to ensure production of quality poultry products must be met from organically produced and very well-known with the contents of feedstuff digestibility. In this study, the problems encountered in feeding can be eliminated while performing economic production with considering animal welfare, following that balanced and adequate organic ration formulations and issues such as improving the production of feed raw materials are discussed.

The treatments consisted of six diets: R+S: free-choice feeding with rice bran (energy and soybean meal (protein; C+G: free-choice feeding with corn (energy and corn gluten meal (protein; R+G: free-choice feeding with rice bran (energy and corn gluten meal (protein; C+S: free-choice feeding with corn (energy and soybean meal (protein; R+C+G+S: free-choice feeding with rice bran and corn (energy and corn gluten meal and soybean meal (protein; and BD: basal diet represented by a complete diet composed of 63% corn and 33% soybean meal. The results indicated that the adjustment to nutritional requirements does not depend only on the ability of birds to select feed. It might also depend on intake and ingredient quality, since some ingredients did not provide a balanced amount of nutrients. The birds were able to fulfill their requirements for maintenance, that is, they consumed the minimum amount of amino acids (g per day for maximum growth. The free-choice group with corn gluten meal as the protein source had the worst performance, which indicated that this feed is not recommended as a primary source of amino acids for broilers. The C+G diet presented the highest digestibility coefficient of dry matter and crude protein, whereas the C+S diet resulted in the highest digestibility coefficient of ether extract and nitrogen-free extract, indicating that diet digestibility was affected by the type of feed used as energy and protein sources. In general, the high digestibility values indicate that broilers are able to efficiently digest and absorb the supplied feed.

    This study assesses the suitability of vegetable waste produced by food industry for use as a raw material for animal feed. It includes safety and nutritional viability, technical feasibility and environmental evaluation. Vegetable by-products were found to be nutritionally and sanitarily appropriate for use in animal feed. The drying technologies tested for making vegetable waste suitable for use in the animal feed market were pulse combustion drying, oven and microwave. The different meal prototypes obtained were found to comply with all the requirements of the animal feed market. An action plan that takes into account all the stages of the valorisation process was subsequently defined in agreement with local stakeholders. This plan was validated in a pilot-scale demonstration trial. Finally, the technical feasibility was studied and environmental improvement was performed. This project was funded by the European LIFE+ program (LIFE09 ENV/ES/000473). Copyright © 2015 Elsevier Ltd. All rights reserved.

    2012-01-01

    Background Associations between parent and child characteristics and how they influence the approach parents take toward children in the feeding environment have not been examined extensively, especially in low-income minority families who are at a higher risk for obesity. The primary aim of the study was to examine positive and negative parent emotions as potential mediators of the relationship between child temperament and parents’ perceptions of strategy effectiveness and problems encountered in feeding children fruit and vegetables. Methods Participants were low-income families (n = 639, 73% minority, children aged 3–5 years) participating in Head Start programs in two states. Parents completed the Children’s Behavior Questionnaire (CBQ), Positive and Negative Affect Schedule (PANAS), and measures of strategy effectiveness (teachable moments, practical methods, restriction, and enhanced availability) and problems encountered (vegetable characteristics, child attributions for dislike, external influences, and parental demands) in feeding children fruit and vegetables. Results Positive parent emotions partially mediated the relationship between child Effortful Control and strategy effectiveness and fully mediated the relationship between Surgency and strategy effectiveness. Although negative parent emotions were associated with increased perception of problems in feeding children fruit and vegetables, the relationship between Negative Affectivity and problems in feeding was partially mediated by negative parent emotions. Conclusions Positive parent emotions facilitated perceived effectiveness of feeding strategies, with child Effortful Control and Surgency instrumental to this process. Understanding mechanisms in parent–child feeding is important when developing interventions designed to promote healthy child eating behaviors. PMID:22643039

    Conventional and newly emerging treatment procedures such as chemotherapy, catalytic therapy, photodynamic therapy and radiotherapy have not succeeded in reversing the outcome of cancer diseases to any drastic extent, which has led researchers to investigate alternative treatment options. The extensive repertoire of traditional medicinal knowledge systems from various parts of the world are being re-investigated for their healing properties Crocus sativus L., commonly known as saffron, is the raw material for one of the most expensive spice in the world, and it has been used in folk medicine for centuries. Chemical analysis has shown the presence of more than 150 components in saffron stigmas. The more powerful components of saffron are crocin, crocetin and safranal. Studies in animal models and with cultured human malignant cell lines have demonstrated antitumor and cancer preventive activities of saffron and its main ingredients, possible mechanisms for these activities are discussed. More direct evidence of anticancer effectiveness of saffron as chemo-preventive agent may come from trials that use actual reduction of cancer incidence as the primary endpoint. This review discusses recent literature data and our results on the cancer chemopreventive activities of saffron and its main ingredients. PMID:24761112

    Obesity is considered as a chronic disease that can induce a series of comorbidities and complications. Chinese medicine has long clinical experiences in the treatment of obesity. This review summarizes the natural products from traditional Chinese medicine (TCM) that are reported to have anti-obesity effects in the past two decades. Botanic TCM comprises 90% of total Chinese crude drugs, and generally contains various active ingredients, in which the effective anti-obesity ingredients identified can be divided into saponins, polysaccharides, alkaloids, polyphenols and others. Astragaloside IV, glycyrrhizin, macrostemonoside A, berberine, betaine, capsaicin, matrine, methyl piperate, piperine, rutaecarpine, asimilobine, epigallocatechingallate, magnolol, resveratrol, soybean-isoflavone, α-linolenic acid, emodin, geniposide, phillyrin, salidroside and ursolic acid are specified in this review, and their sources, models, efficacy are described. It is concluded that the mechanisms of these components for the treatment of obesity include: (i) suppression of appetite, increase of satiety, reduction of energy intake; (ii) reduction in the digestion and absorption of exogenous lipid; (iii) attenuation of the synthesis of endogenous lipid; (iv) promotion of the oxidation and expenditure of lipid and (v) improvement of lipid metabolism disorder. Authors believe that the effective compounds from TCM will provide an alternative and hopeful way for the treatment of obesity. © 2014 World Obesity.

  5. Delivering Improved Nutrition: Dairy Ingredients in Food Aid Products.

    2016-03-01

    The United States has a long history of food assistance for humanitarian need. The Food for Peace Act of 1954 established the United States' permanent food assistance program which has fed over 3 billion people in 150 countries worldwide through thousands of partner organizations. In 60 years, the program has evolved and will continue to do so. Recently, the program has gone from a focus on quantity of food shipped to quality food assistance from improved products, programs, and processes to effectively meet the needs of different vulnerable groups. The current debate focuses on the appropriateness of using fortified blended foods to prevent and treat malnutrition during the first 1000 days of life. Dairy ingredients have been at the center of this debate; they were included initially in fortified blended, removed in the 1980s, and now reincorporated into fortified therapeutic and supplemental foods. Improved quality food baskets and effective nutrition programming to prevent and treat malnutrition were developed through multisectoral collaboration between government and nongovernment organizations. The US Agency for International Development has focused on improving nutrition through development programs often tied to health, education, and agriculture. The years since 2008 have been a particularly intense period for improvement. The Food Aid Quality Review was established to update current food aid programming products, program implementation, cost-effectiveness, and interagency processes. Trials are underway to harmonize the areas of multisectoral nutrition programming and gather more evidence on the effects of dairy ingredients in food aid products. © The Author(s) 2016.

  6. Database search for safety information on cosmetic ingredients.

    2007-12-01

    Ethical considerations with respect to experimental animal use and regulatory testing are worldwide under heavy discussion and are, in certain cases, taken up in legislative measures. The most explicit example is the European cosmetic legislation, establishing a testing ban on finished cosmetic products since 11 September 2004 and enforcing that the safety of a cosmetic product is assessed by taking into consideration "the general toxicological profile of the ingredients, their chemical structure and their level of exposure" (OJ L151, 32-37, 23 June 1993; OJ L066, 26-35, 11 March 2003). Therefore the availability of referenced and reliable information on cosmetic ingredients becomes a dire necessity. Given the high-speed progress of the World Wide Web services and the concurrent drastic increase in free access to information, identification of relevant data sources and evaluation of the scientific value and quality of the retrieved data, are crucial. Based upon own practical experience, a survey is put together of freely and commercially available data sources with their individual description, field of application, benefits and drawbacks. It should be mentioned that the search strategies described are equally useful as a starting point for any quest for safety data on chemicals or chemical-related substances in general.

  7. Technological Challenges for Spray Chilling Encapsulation of Functional Food Ingredients

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Spray chilling technology (also known as spray cooling and spray congealing technology has been widely studied and used in the pharmaceutical field. In the food industry, this technique is gaining interest and can become useful because functional food formulations can be developed. Spray chilling is a fat-based system, which involves the addition of the component of interest to a molten lipid carrier, and the resulting mixture is fed through an atomiser nozzle. When the nebulised material is put into contact with the environment, which is cooled below the melting point of the matrix material, the vehicle solidifies (due to heat exchange between the molten material and cold air, and solid lipid microparticles are formed at the same time. This technology is fat based, and lipid carriers, such as wax and oil (e.g. palm oil, beeswax, cocoa butter, and kernel oil can be used. This encapsulation technique can potentially change the functionality, reduce the hygroscopicity, mask taste or odour, change solubility, and provide physical protection in addition to allowing the controlled release of these ingredients. This low-cost technology is relatively simple to apply and scale up, and it does not require the use of organic solvents and the application of high temperatures in the process. Therefore, spray chilling encapsulation may facilitate the development and production of functional and enriched foods as it may solve some technological problems associated with the use of certain ingredients, such as those that have high reactivity and low stability.

    Food allergic consumers depend on ingredient labels for allergen avoidance, and the modality of labeling is changing. To investigate current responses to food labels so that the impact of future label changes can be anticipated. Adults who attended Food Allergy & Anaphylaxis Network conferences completed a survey regarding their experiences with food labels for their family's most severely affected food allergic individual (FAI). There were 489 completed surveys (84% participation). Most FAIs were young (41% allergies included the following: peanut, 81%; tree nuts, 53%; milk, 51%; egg, 51%; and soy, 17%. All chocolate products were avoided by 37% of FAIs who were avoiding peanut and 40% who were avoiding tree nuts; 91% of tree nut allergic FAIs avoided all tree nuts. Of FAIs who avoided soy, 41% avoided soybean oil and 38% avoided soy lecithin. Of those who avoided milk, 82% avoided lactose. Allergic reactions were attributed to misunderstanding label terms (16%) and to nonspecific terms (spice, flavor) (22%). Ingredient labels were "always" or "frequently" read before purchase by 99%. Product brand choice was "very much influenced" by the manner of labeling for 86%, and manufacturers were contacted for more information by 86%. Our results suggest that improved product allergen labeling will reduce allergic reactions and simplify allergy management. However, the new labeling may not indicate the form or source of the allergen, and individuals who do not currently avoid foods with minimal or irrelevant protein content, such as soy oil or soy lecithin, may face additional ambiguity and unnecessary dietary restrictions.

    2009-06-01

    Baker's yeast is one of the oldest food microbial starters. Between 1927 and 2008, 165 inventions on more than 337 baker's yeast strains were patented. The first generation of patented yeast strains claimed improved biomass yield at the yeast plant, higher gassing power in dough or better survival to drying to prepare active dry baker's yeast. Especially between 1980 and 1995, a major interest was given to strains for multiple bakery applications such as dough with variable sugar content and stored at refrigeration (cold) or freezing temperatures. During the same period, genetically engineered yeast strains became very popular but did not find applications in the baking industry. Since year 2000, patented baker's yeast strains claimed aroma, anti-moulding or nutritive properties to better meet the needs of the baking industry. In addition to patents on yeast strains, 47 patents were issued on baker's yeast specialty ingredients for niche markets. This review shows that patents on baker's yeast with improved characteristics such as aromatic or nutritive properties have regularly been issued since the 1920's. Overall, it also confirms recent interest for a very wide range of tailored-made yeast-based ingredients for bakery applications.

  10. EU legislations affecting safety data availability of cosmetic ingredients.

    Pauwels, Marleen; Rogiers, Vera

    2007-12-01

    With the introduction of the 6th and 7th Amendments (OJ L151, 32-37, 23 June 1993; OJ L066, 26-35, 11 March 2003) to the Cosmetic Products Directive (OJ L262, 169-200, 27 September 1976), imposing a testing and marketing ban on cosmetic products tested on animals, the retrieval of toxicological data on individual ingredients became of greater need. Since the majority of cosmetic ingredients are used for many other purposes than their cosmetic function, they fall under the scope of more than one EU Directive. An overview is given of EU legislation that could potentially affect the availability and interpretation of cosmetic safety data. It will become clear that, although cosmetics are regulated by a specific so-called "vertical" legislation, "horizontal" influences from other products' legislations play a role since they determine the type and amount of data that theoretically could be found on the specific substances they regulate. This knowledge is necessary while performing extended searches in databases and becomes indispensable when initiating negotiations with manufacturers or suppliers for obtaining the safety data required.

    Céline Couteau

    Full Text Available BACKGROUND: To explain observed differences during SPF determination using either an in vivo or in vitro method, we hypothesized on the presence of ingredients having anti-inflammatory properties. METHODOLOGY/PRINCIPAL FINDINGS: To research our hypothesis, we studied the 21 UV filters both available on the market and authorized by European regulations and subjected these filters to the phorbol-myristate-acetate test using mice. We then catalogued the 13 filters demonstrating a significant anti-inflammatory effect with edema inhibition percentages of more than 70%. The filters are: diethylhexyl butamido triazone (92%, benzophenone-5 and titanium dioxide (90%, benzophenone-3 (83%, octocrylène and isoamyl p-methoxycinnamate (82%, PEG-25 PABA and homosalate (80%, octyl triazone and phenylbenzimidazole sulfonic acid (78%, octyl dimethyl PABA (75%, bis-ethylhexyloxyphenol methoxyphenyl triazine and diethylamino hydroxybenzoyl hexylbenzoate (70%. These filters were tested at various concentrations, including their maximum authorized dose. We detected a dose-response relationship. CONCLUSIONS/SIGNIFICANCE: The anti-inflammatory effect of a sunscreen ingredient may affect the in vivo SPF value.

  12. Consumers’ Attitude toward Sustainable Food Products: Ingredients vs. Packaging

    Full Text Available The availability of and preference for eco-friendly products have increased; however, understanding of sustainable products is still insufficient because most studies have been focused only on organic products. The availability and understanding of organic products are high, but not complete. With regards to environmental protection, it is important to focus not only on the eco-friendly ingredients but also on the eco-friendly packaging because packaging has recently been found to be a primary cause of pollution. Through three studies, this article investigated the interaction between the effect of consumers’ willingness to buy (WTB, the price premium for eco-friendliness (internal: eco-friendly ingredients vs. external: eco-friendly packaging, and the product’s attributes. Three experimental studies were conducted to determine whether the consumers’ WTB and the price premium for sustainable products differ according to the eco-friendliness of the product and the product’s attributes. In Study 1 and Study 3, analysis of variance (ANOVA was conducted; and, in Study 2, analysis of covariance (ANCOVA was conducted. The results of Study 1 and Study 2 suggested that the consumers’ WTB for sustainable products can differ according to the product’s attribute. Moreover, results of Study 3 revealed that consumers’ WTB and satisfaction for sustainable products can differ according to level of packaging.

  13. Plant Cell Cultures as Source of Cosmetic Active Ingredients

    2014-04-01

    Full Text Available The last decades witnessed a great demand of natural remedies. As a result, medicinal plants have been increasingly cultivated on a commercial scale, but the yield, the productive quality and the safety have not always been satisfactory. Plant cell cultures provide useful alternatives for the production of active ingredients for biomedical and cosmetic uses, since they represent standardized, contaminant-free and biosustainable systems, which allow the production of desired compounds on an industrial scale. Moreover, thanks to their totipotency, plant cells grown as liquid suspension cultures can be used as “biofactories” for the production of commercially interesting secondary metabolites, which are in many cases synthesized in low amounts in plant tissues and differentially distributed in the plant organs, such as roots, leaves, flowers or fruits. Although it is very widespread in the pharmaceutical industry, plant cell culture technology is not yet very common in the cosmetic field. The aim of the present review is to focus on the successful research accomplishments in the development of plant cell cultures for the production of active ingredients for cosmetic applications.

  14. Macroalgae-Derived Ingredients for Cosmetic Industry—An Update

    Filipa B. Pimentel

    2017-12-01

    Full Text Available Aging is a natural and progressive declining physiological process that is influenced by multifactorial aspects and affects individuals’ health in very different ways. The skin is one of the major organs in which aging is more evident, as it progressively loses some of its natural functions. With the new societal paradigms regarding youth and beauty have emerged new concerns about appearance, encouraging millions of consumers to use cosmetic/personal care products as part of their daily routine. Hence, cosmetics have become a global and highly competitive market in a constant state of evolution. This industry is highly committed to finding natural sources of functional/bioactive-rich compounds, preferably from sustainable and cheap raw materials, to deliver innovative products and solutions that meet consumers’ expectations. Macroalgae are an excellent example of a natural resource that can fit these requirements. The incorporation of macroalgae-derived ingredients in cosmetics has been growing, as more and more scientific evidence reports their skin health-promoting effects. This review provides an overview on the possible applications of macroalgae as active ingredients for the cosmetic field, highlighting the main compounds responsible for their bioactivity on skin.

  15. Hydroxytyrosol: Health Benefits and Use as Functional Ingredient in Meat

    Directory of Open Access Journals (Sweden)

    Lorena Martínez

    2018-01-01

    Full Text Available Hydroxytyrosol (HXT is a phenolic compound drawn from the olive tree and its leaves as a by-product obtained from the manufacturing of olive oil. It is considered the most powerful antioxidant compound after gallic acid and one of the most powerful antioxidant compounds between phenolic compounds from olive tree followed by oleuropein, caffeic and tyrosol. Due to its molecular structure, its regular consumption has several beneficial effects such as antioxidant, anti-inflammatory, anticancer, and as a protector of skin and eyes, etc. For these reasons, the use of HXT extract is a good strategy for use in meat products to replace synthetics additives. However, this extract has a strong odour and flavour, so it is necessary to previously treat this compound in order to not alter the organoleptic quality of the meat product when is added as ingredient. The present review exposes the health benefits provided by HXT consumption and the latest research about its use on meat. In addition, new trends about the application of HXT in the list of ingredients of healthier meat products will be discussed.

  16. Prebiotics as functional food ingredients preventing diet-related diseases.

    Science.gov (United States)

    Florowska, A; Krygier, K; Florowski, T; Dłużewska, E

    2016-05-18

    This paper reviews the potential of prebiotic-containing foods in the prevention or postponement of certain diet-related diseases, such as cardiovascular diseases with hypercholesterolemia, osteoporosis, diabetes, gastrointestinal infections and gut inflammation. Also the data on prebiotics as food ingredients and their impact on food product quality are presented. Prebiotics are short chain carbohydrates that are resistant to the digestion process in the upper part of the digestive system, are not absorbed in any segment of the gastrointestinal system, and finally are selectively fermented by specific genera of colonic bacteria. The mechanisms of the beneficial impacts of prebiotics on human health are very difficult to specify directly, because their health-promoting functions are related to fermentation by intestinal microflora. The impact of prebiotics on diet-related diseases in many ways also depends on the products of their fermentation. Prebiotics as functional food ingredients also have an impact on the quality of food products, due to their textural and gelling properties. Prebiotics as food additives can be very valuable in the creation of functional food aimed at preventing or postponing many diet-related diseases. They additionally have beneficial technological properties which improve the quality of food products.

  17. Ingredient classification according to the digestible amino acid profile: an exploratory analysis

    2005-09-01

    Full Text Available This study aimed: 1 to classify ingredients according to the digestible amino acid (AA profile; 2 to determine ingredients with AA profile closer to the ideal for broiler chickens; and 3 to compare digestible AA profiles from simulated diets with the ideal protein profile. The digestible AA levels of 30 ingredients were compiled from the literature and presented as percentages of lysine according to the ideal protein concept. Cluster and principal component analyses (exploratory analyses were used to compose and describe groups of ingredients according to AA profiles. Four ingredient groups were identified by cluster analysis, and the classification of the ingredients within each of these groups was obtained from a principal component analysis, showing 11 classes of ingredients with similar digestible AA profiles. The ingredients with AA profiles closer to the ideal protein were meat and bone meal 45, fish meal 60 and wheat germ meal, all of them constituting Class 1; the ingredients from the other classes gradually diverged from the ideal protein. Soybean meal, which is the main protein source for poultry, showed good AA balance since it was included in Class 3. On the contrary, corn, which is the main energy source in poultry diets, was classified in Class 8. Dietary AA profiles were improved when corn and/or soybean meal were partially or totally replaced in the simulations by ingredients with better AA balance.

  17. [Examination of processed vegetable foods for the presence of common DNA sequences of genetically modified tomatoes].

    Science.gov (United States)

    Kitagawa, Mamiko; Nakamura, Kosuke; Kondo, Kazunari; Ubukata, Shoji; Akiyama, Hiroshi

    2014-01-01

    The contamination of processed vegetable foods with genetically modified tomatoes was investigated by the use of qualitative PCR methods to detect the cauliflower mosaic virus 35S promoter (P35S) and the kanamycin resistance gene (NPTII). DNA fragments of P35S and NPTII were detected in vegetable juice samples, possibly due to contamination with the genomes of cauliflower mosaic virus infecting juice ingredients of Brassica species and soil bacteria, respectively. Therefore, to detect the transformation construct sequences of GM tomatoes, primer pairs were designed for qualitative PCR to specifically detect the border region between P35S and NPTII, and the border region between nopaline synthase gene promoter and NPTII. No amplification of the targeted sequences was observed using genomic DNA purified from the juice ingredients. The developed qualitative PCR method is considered to be a reliable tool to check contamination of products with GM tomatoes.

    Licorice extract (block, powder or liquid) may be applied to cigarette tobacco at levels of about 1-4% to enhance and harmonize the flavor characteristics of smoke, improve moisture holding characteristics of tobacco, and act as a surface active agent for ingredient application. Neat material pyrolysis studies, and smoke chemistry and biological activity studies (bacterial mutagenicity, cytotoxicity, micronucleus, and sub-chronic inhalation) with mainstream smoke, or mainstream smoke preparations from cigarettes containing various target levels (1.5-12%) of the licorice extracts were performed to provide data for an assessment of the use of licorice extract as a cigarette tobacco ingredient. At simulated tobacco burning temperatures up to 900 degrees C all forms of neat licorice extract pyrolyzed extensively, yielding small amounts of benzene, toluene, phenol and acetaldehyde with no indication that licorice extracts would transfer intact to mainstream smoke. As a single ingredient added to cigarette tobacco, block licorice extract at a target level of 12.5% increased smoke constituents including selected PAH, arsenic, lead, phenol and formaldehyde (on a TPM basis), while licorice extract powder (target level of 8% tobacco) increased select PAH, phenol and formaldehyde (on a TPM basis). Lower target application levels (including typical application levels) of block, powder or liquid licorice extract did not significantly alter the smoke chemistry profile. Biological tests indicated no relevant difference in the genotoxic or cytotoxic potential of either mainstream smoke (or smoke preparations) from cigarettes with added licorice extracts compared to control cigarettes. In sub-chronic 90-day rat inhalation studies, the mainstream smoke from cigarettes with 12.5% added block and 8% added powder licorice extract contained higher formaldehyde concentrations compared to control cigarette smoke. Female rats in the 12.5% block licorice extract exposure group displayed an

    To investigate the microbial and nutritional characteristics of dry feed, liquid feed containing fermented liquid cereal grains, and fermented liquid feed, and their effect on gastrointestinal ecology and growth performance, 120 piglets from 40 litters were used and housed in pens with 5 animals in each. The 3 dietary treatments (all nonheated and nonpelleted diets) were: a dry meal diet (DRY); a fermented, liquid cereal grain feed (FLG); and a fermented liquid feed (FLF). The FLG diet was prepared by storing the dietary cereals (barley and wheat) and water (1:2.5, wt/wt) in a closed tank at 20 degrees C and adding the remaining dietary ingredients immediately before feeding. The FLF diet was prepared by storing compound feed and water (1:2.5, wt/wt) in a closed tank at 20 degrees C. Three times daily, 50% of the fermented cereals or compound feed and water stored in the tanks was removed and replaced with an equal amount of fresh cereals or feed and water. On d 14, 1 piglet from each pen was killed and samples from the gastrointestinal tract were obtained. The pH of the fermented cereals was 3.85 (SD = 0.10), that of the FLG diet was 5.00 (SD = 0.18), and the pH of the FLF diet was 4.45 (SD = 0.11). The dietary concentration of lysine (g/16 g of N) pointed to a decreased concentration in the FLF (5.46, SD = 0.08) compared with the DRY (6.01) and FLG (6.21, SD = 0.27) diets, and the concentration of cadaverine was greater in the FLF diet (890 mg/kg, SD = 151.3) than in the DRY (32 mg/kg) or FLG (153 mg/kg, SD = 18.7) diets. Fermenting only the cereal component of the diet (FLG) promoted the growth of yeasts to a greater extent than fermenting the whole diet (FLF). Terminal RFLP profiles of diets and digesta from the stomach and midcolon showed differences among dietary groups. The number of yeasts able to grow at 37 degrees C in the stomach and caudal small intestine was greatest in the FLG group compared with the other 2 dietary groups (P liquid feed containing
