    Full Text Available The main objective of this work was the production of syrups dextrinized by enzymatic hydrolysis of starch red sorghum CIAPR-132 using α-amylase on solutions at different concentrations, with different concentrations of enzyme and enzyme hydrolysis time. The response variable was the dextrose equivalent in each obtained syrup (ED using the modified Lane-Eynon method. In some of the experiments, we used a full factorial design 23 and in others we worked with intermediate concentration and higher hydrolysis time with different levels of enzyme. The obtained products were syrups dextrinized ED between 10,25 and 33,97% (values we can find within the established ones for these types of syrups, which can be used for their functional properties as intermediates syrups or as raw material for different processes of the food industry. This allows you to set a pattern for the use of sorghum feedstock in unconventional obtaining products from its starch.

    Rice can be a major source of inorganic arsenic (Asi) for many sub-populations. Rice products are also used as ingredients in prepared foods, some of which may not be obviously rice based. Organic brown rice syrup (OBRS) is used as a sweetener in organic food products as an alternative to high-fructose corn syrup. We hypothesized that OBRS introduces As into these products. We determined the concentration and speciation of As in commercially available brown rice syrups and in products containing OBRS, including toddler formula, cereal/energy bars, and high-energy foods used by endurance athletes. We used inductively coupled plasma mass spectrometry (ICP-MS) and ion chromatography coupled to ICP-MS to determine total As (Astotal) concentrations and As speciation in products purchased via the Internet or in stores in the Hanover, New Hampshire, area. We found that OBRS can contain high concentrations of Asi and dimethyl-arsenate (DMA). An "organic" toddler milk formula containing OBRS as the primary ingredient had Astotal concentrations up to six times the U.S. Environmental Protection Agency safe drinking water limit. Cereal bars and high-energy foods containing OBRS also had higher As concentrations than equivalent products that did not contain OBRS. Asi was the main As species in most food products tested in this study. There are currently no U.S. regulations applicable to As in food, but our findings suggest that the OBRS products we evaluated may introduce significant concentrations of Asi into an individual's diet. Thus, we conclude that there is an urgent need for regulatory limits on As in food.

    With the ever-increasing demand for sugar and the trend in rising price, rapid progress in research on new and/or alternative sweeteners has been inevitable during the past decade or so. Pure glucose, glucose/fructose, glucose/maltose syrups are often called isosyrups. Isosyrups have been recognized as a good alternative sources of sugar. These are used today in the manufacture of soft drinks, jams and jellies, confectionary, baking fermentation, dietetic and infant food, ice-cream, pharmaceutical processes, etc. Isosyrups are produced by hydrolysis of starch and cellulocis raw materials have been utilized for the production of isosyrups.

    Maple syrup urine disease (MSUD) is an inborn error of metabolism caused by defects in the branched-chain α-ketoacid dehydrogenase complex, which results in elevations of the branched-chain amino acids (BCAAs) in plasma, α-ketoacids in urine, and production of the pathognomonic disease marker, alloisoleucine. The disorder varies in severity and the clinical spectrum is quite broad with five recognized clinical variants that have no known association with genotype. The classic presentation occurs in the neonatal period with developmental delay, failure to thrive, feeding difficulties, and maple syrup odor in the cerumen and urine, and can lead to irreversible neurological complications, including stereotypical movements, metabolic decompensation, and death if left untreated. Treatment consists of dietary restriction of BCAAs and close metabolic monitoring. Clinical outcomes are generally good in patients where treatment is initiated early. Newborn screening for MSUD is now commonplace in the United States and is included on the Recommended Uniform Screening Panel (RUSP). We review this disorder including its presentation, screening and clinical diagnosis, treatment, and other relevant aspects pertaining to the care of patients.

    2014-01-01

    The pasting and gel textural properties of corn starch in syrup at different concentrations were investigated by Rapid Visco Analyzer (RVA) and Texture profile analysis (TPA) tests. The results showed that the pasting temperatures of corn starch greatly increased, especially at higher sugar concentration. Increasing concentration of syrup caused an increase in peak, trough and final viscosity of corn starch. Peak viscosity and the disintegration rate of starch increased in the following order: fructose syrup> maltose syrup> glucose syrup. Increasing syrup concentration to 13%, 25% and 50% resulted in a lower retrogradation rate than the control. When the maltose syrup concentration increased to 50%, the retrogradation rate decreased to 14.30% from 33.38%. The highest hardness was observed when the syrup concentration was 25%. There was a particular low hardness when the concentration of syrup was 50%. The springiness of starch gels in syrup was similar at different concentrations.

    The aim of this study was to investigate the possibility of using dates syrup as a tablet binder. Dates syrup (40%, 50%, 60% w/w dates syrup:water) was utilized for the granulation of sodium bicarbonate and calcium carbonate as examples for water-soluble and water-insoluble materials; correspondingly. Those two materials represent examples of bulky drugs as well. Starch paste (10% w/w starch in water) and sucrose syrup (50% w/w sucrose in water), the well-known tablet binders, were used in the granulation of the same materials for the sake of comparison. The granulations were evaluated with regard to particle size and particle size distribution, granule strength, bulk density, flowability, moisture content and compression behavior. In addition, tablets prepared and evaluated from these granules. Taste and flavor of the prepared tablet have been tested by seven healthy volunteers. Within the scope of this work, dates syrup showed excellent properties as a tablet binder in comparison to starch paste or sucrose syrup for the granulation of both water-soluble and water-insoluble materials. Also, better flavoring and masking taste have been noticed from an evaluation by human volunteers demonstrating the usefulness of the date syrup as sweetener and flavoring the tablets in addition to its use as binder.

    Maple syrup is a widely consumed plant-derived natural sweetener produced by concentrating xylem sap collected from certain maple (Acer) species. During thermal evaporation of water, natural phytochemical components are concentrated in maple syrup. The polymeric components from maple syrup were isolated by ethanol precipitation, dialysis, and anion exchange chromatography and structurally characterized by glycosyl composition analysis, glycosyl linkage analysis, and nuclear magnetic resonance spectroscopy. Among the maple syrup polysaccharides, one neutral polysaccharide was characterized as inulin with a broad molecular weight distribution, representing the first isolation of this prebiotic carbohydrate from a xylem sap. In addition, two acidic polysaccharides with structural similarity were identified as arabinogalactans derived from rhamnogalacturonan type I pectic polysaccharides.

    Effects of date syrup on pasting, rheological, and retrogradation properties of low-amylose rice starch were investigated using three levels of date syrup (starch:syrup 1:1, 1:2, or 1:3). Measurements were carried out using HR-2 Discovery Rheometer equipped with a pasting cell and parallel plate geometry. The pasting measurements showed that the peak viscosity of the control is significantly higher than the samples with date syrup (p syrup levels. Addition of date syrup increases the solid-like behavior of the gel in reverse order with increased date syrup levels. Low-amylose starch gel used in this study showed minor changes in elastic modulus (G') during one week cold storage indicting that low-amylose rice starch is resistant to retrogradation. Addition of date syrup slightly resulted in increased retrogradation compared to the control.

    Full Text Available Three different starch syrups available on the Polish market for winter feeding of bees were evaluated for two consecutive beekeeping seasons (2012/2013 and 2013/2014. Sugar syrup and inverted sucrose syrup were used as the control. Winter feeding was conducted at two times: earlier and later in the season. After supplementation of winter feeding was stopped, we measured colony strength (number of combs covered by bees and brood area. After overwintering (spring 2013 and 2014, we estimated the influence of these foods on: bee mortality during overwintering (number of dead bees in winter debris, food consumption, colony strength and brood area in spring (two measurements in three-week intervals, development dynamics and honey yield from spring flow. An analysis of the results for the parameters assessed before overwintering, after its end and during spring development did not show significant differences between bee colonies fed with different types of food. No relevant difficulties concerning food crystallisation were encountered. The analysed syrups turned out to be as suitable for winter feeding of bees as sugar and inverted sucrose syrups.

    This study demonstrates the efficient utilization of low-cost agricultural substrates, particularly date syrup, by Schizophyllum commune ATCC 38548 for schizophyllan production. Initially, one factor-at-a-time method was used to find the best carbon and nitrogen sources for schizophyllan production. Subsequently, response surface methodology was employed to optimize the level of culture medium components to maximize substrate conversion yield and schizophyllan production in submerged culture. Maximum product yield (0.12g schizophyllan/g date syrup) and schizophyllan production (8.5g/l) were obtained at concentrations of date syrup and corn steep liquor, inoculum size and agitation rate at 7.02%w/v, 0.10%w/v, 7.68%v/v and 181rpm, respectively. Sugar composition analysis, FTIR, NMR and molar mass determination revealed the purity and molecular properties of recovered schizophyllan produced from date syrup as glycosidic linkage analysis showed three main schizophyllan characteristic peaks arising from the 3-linked, 3,6-linked and terminal glucose residues. Finally, process economic analysis suggested that use of date syrup and corn steep liquor as nutrients would result in approximately 6-fold reduction in cost of raw materials for schizophyllan production as compared to conventional carbon and nitrogen sources such as sucrose and malt extract.

    Palm syrup is a typical product from the Canary Islands, traditionally produced from the sap of the tropical palm tree Phoenix canariensis. Its high caloric content has led to its increasing use as a health food supplement for athletes, children and elderly. Furthermore, demand for this natural syrup is continuously increasing due also to its medicinal uses in homeopathic medicine. Palm Tree syrup samples prepared with palm sap from primary producers in La Gomera island (Canary Islands, Spain) were analyzed for their nutritional composition (moisture, ash, sugars, fat, vitamins and minerals). 35 syrup samples from five different producing regions in La Gomera island were analyzed. High-performance liquid chromatography (HPLC) was used to determine sugars and vitamins and Flame Atomic Absorption Spectrophotometry (FAAS) was used to analyze the minerals. Major carbohydrates were sucrose (37.8%), glucose (9.50%) and fructose (4.80%), respectively. The presence of arabinose could not be confirmed. Niacin was the water-soluble vitamin with the highest concentration with an average content of 0.003%. Fat content was found to be under 0.20%. Potassium was the mineral with highest contents (0.45%). Results suggest that palm tree syrup can play an important role as a sugar and mineral source in human nutrition, suggesting that future applications for this product could be developed.

    Pontal syrup was administered at daily dose of 30 ml t. i. d. to 17 patients of mucositis developed due to radiotherapy against malignant tumor. Results were: Remarkably effective-5 cases, effective-8 cases, slightly effective-3 cases, and non-effective-1 case. Certain effects were observed in 16 cases out of 17 cases/94.1%, excluding only one non-effective case. No side-effects were observed in all cases. It is considered that Pontal syrup is a drug useful for mucositis caused by radiotherapy because of its easiness of administration and also of its characteristic of non-stimulant. (author)

    Maple syrup is a natural sweetener that is commonly consumed worldwide. While maple syrup mainly comprises sucrose, it also contains phytochemicals that present various biological effects. Maple syrup is made by boiling down sap, and its color and composition vary in accordance with the sap collection season. Typically, seasonal progression is associated with darker syrup color, and antioxidant activity is proportional to the increasingly dark color. The authors previously reported that maple syrup demonstrated inhibitory effects on colorectal cancer cell growth and invasion, which correlated with darker maple syrup color. In the present study, they examined the effects of two different grades of maple syrup on gastrointestinal cancer cell proliferation, to investigate whether the dark-color maple syrup was suitable as a phytomedicine for gastrointestinal cancer treatment. Administration of dark-color maple syrup significantly inhibited gastrointestinal cancer cell growth as compared to non-treated cancer cells. Moreover, administration of dark-color maple syrup clearly inhibited protein kinase B (AKT) phosphorylation and did not impact mitogen-associated protein kinase phosphorylation. These data suggested that dark-color maple syrup may inhibit cell proliferation through suppression of AKT activation and, thus, may be suitable as a phytomedicine for gastrointestinal cancer treatment.

    Maple syrup is a natural sweetener consumed by individuals of all ages throughout the world. Maple syrup contains not only carbohydrates such as sucrose but also various components such as organic acids, amino acids, vitamins and phenolic compounds. Recent studies have shown that these phenolic compounds in maple syrup may possess various activities such as decreasing the blood glucose level and an anticancer effect. In this study, we examined the effect of three types of maple syrup, classified by color, on the cell proliferation, migration and invasion of colorectal cancer (CRC) cells in order to investigate whether the maple syrup is suitable as a phytomedicine for cancer treatment. CRC cells that were administered maple syrup showed significantly lower growth rates than cells that were administered sucrose. In addition, administration of maple syrup to CRC cells caused inhibition of cell invasion, while there was no effect on cell migration. Administration of maple syrup clearly inhibited AKT phosphorylation, while there was no effect on ERK phosphorylation. These data suggest that maple syrup might inhibit cell proliferation and invasion through suppression of AKT activation and be suitable as a phytomedicine for CRC treatment, with fewer adverse effects than traditional chemotherapy.

    Fifty different pediatric syrups were randomly sampled from patent medicine stores and pharmaceutical shops within Awka, in Anambra State between November 2007 and May 2008. Syrups were ashed before digestion using conc. aqua regia, HCl:HNO{sub 3} (3:1) and lead and cadmium were assayed with AAS 205A. Results revealed that 60 and 98% of the sample size had lead and cadmium respectively. The lead levels ranged from 0.01 in chloroquine to 1.08 mg/l in magcid suspension. The highest level of cadmium was seen in magcid suspension with concentration of 2.45 mg/l while lowest concentration of 0.01 in emzolyn and colipan. About 41.2% of the locally made syrup had none detectable levels of lead while all the syrup had detectable levels of cadmium. Lead levels ranged from 0.01 mg/l in cadiphen manufactured in Dholka, India to 0.09 in maxiquine made in England. About 68.8% of the imported syrups of the imported syrups had non detectable levels of lead. Chloramphenicol and zentel albendazole syrups had 0.60 and 0.88 mg/l of cadmium respectively. Bellis cough syrup showed the lowest level (0.01 mg/l) of cadmium. Only erythromycin suspension representing 6.3% had non detectable level of cadmium of the imported syrups. Due to the Cd and Pb levels found, we suggest that the behaviour scenario (here, self administration without medical assistance) should be properly taken under control. Along with this, contamination sources or vulnerable practices during syrups preparation should be also assessed in a tiered approach, towards the minimization of noxious presence in syrups and the promotion of quality of Nigerian-made products.

    Longan (Dimocarpus longan Lour.) syrup is a novel liquid sweetener produced from longan, one of the traditional and economic fruits in the Northern of Thailand. In this research, the effect of extraction and concentration processes on properties of longan syrup was investigated. There were two extraction methods (juice extractor and hydraulic press) and three concentration methods (direct heating, steam heating and vacuum evaporation). Results overall showed that the extraction method had no significant (p ≥ 0.05) effect on longan syrup properties, while concentration resulted in the quality changes of longan syrup. Concentration using direct heating of longan juice caused reduction of sucrose content, and longan syrup dark in color. The headspace volatile compounds of longan syrup were sampled using direct headspace technique and further characterized using gas chromatography-mass spectrometry. The identified volatile compounds could be divided into two groups of aroma characteristics which were (1) floral aroma: 3-methybutyl acetate, (β)-ocimene and 2-phenylethyl alcohol and (2) caramel aroma: butyraldehyde, furfural and benzaldehyde. 2-Phenylethyl alcohol, contributing to floral odor, was retained using vacuum evaporation as a concentration method. Result revealed that the optimal concentration process for longan syrup production was vacuum evaporation, providing the highest floral volatile and lowest caramel volatile. Sensory tests confirmed that longan flavor of the syrup produced from the vacuum evaporation process had significantly higher hedonic scores than other processes.

    The purpose of this study was to compare the in vitro effects of date syrup with those of other contrast agents by qualitative and quantitative analysis and in vivo evaluation of the use of date syrup to improve the quality of MRCP images. Phantoms containing date syrup, ferumoxsil, pineapple juice, and water were imaged by 1.5-T MRI with T2-weighted and MRCP sequences, and signal-to-noise ratios were calculated. Biochemical analysis of date syrup was performed to find the nature of iron in it, and the iron content was quantified by energy-dispersive x-ray spectroscopy. Sixty patients underwent MRCP before and 30 minutes after ingestion of 100 mL of date syrup. Unenhanced and contrast-enhanced images were scored for gastrointestinal tract signal suppression and visualization of various pancreaticobiliary structures. In vitro evaluation showed that images obtained with date syrup had a signal-to-noise ratio comparable to that of images obtained with ferumoxsil in T2-weighted and MRCP sequences. The iron concentration in date syrup was 2.6 mg/dL, and it was in ferric form. Images obtained after oral contrast administration had statistically significant improvement in gastrointestinal tract signal suppression (p syrup can be used as a negative oral contrast agent for gastrointestinal tract signal suppression during MRCP and for improving visualization of various pancreaticobiliary structures.

    2017-01-01

    Full Text Available The treatment and management of acute cough due to common cold costs billions of dollars of healthcare expenditure and there is a growing opinion that a simple linctus containing glycerol with flavourings such as honey and lemon is a safe and effective treatment for acute cough in children and adults. Glycerol is a component of most cough syrups, and although it is often thought of only as a solvent or thickening agent in cough syrups, it may be a major component for the efficacy of cough syrups due to its special properties of lubrication, demulcency, sweetness, and acting as a humectant. The major benefit of cough syrups in soothing cough is likely due to the properties of the syrup rather than the active ingredients and this review discusses the special properties of glycerol in relation to the treatment of acute cough.

    Harris-Haman, Pamela; Brown, Lenora; Massey, Susan; Ramamoorthy, Sivaranjani

    Maple syrup urine disease (MSUD) is an inherited metabolic disorder that affects the body's ability to metabolize amino acids. If left untreated, it places newborns at risk for life-threatening health problems, including episodes of illness called metabolic crisis. Newborn screening for MSUD should ideally be done within the first 24 to 48 hours after birth. With proper screening, along with genetic counseling, nutritional counseling, primary care follow-up, and ongoing monitoring, newborns with MSUD can typically go on to live healthful lives. Nurses play a key role in supporting families with a diagnosis of MSUD. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    In this paper a visual demonstration of optical rotation is presented, with content appropriate for use in a lecture demonstration as well as quantitative techniques suitable for an undergraduate-laboratory experiment. Linearly polarised lasers of various wavelengths are propagated through a glass tube containing corn syrup. The rotation of the plane of polarisation of the light is visible with the naked eye, making the experiment dramatic and engaging and aiding understanding of the phenomenon of optical rotation. In addition, we present a simple approach to quantitatively analyse data using only equipment commonly found in undergraduate teaching laboratories.

    According to saccharide profile comparison between starch syrups and pure honeys analysed through high performance liquid chromatography (HPLC), a characteristic peak was found at 15.25 min retention time in HPLC chromatogram of syrup, but no peak was observed at the same retention time in chromatogram of pure honeys. This characteristic peak for syrup was identified as an overlapping peak of oligosaccharides with more than 5 degree of polymerisation (DP) based on HPLC chromatogram comparison between starch syrup and a series of standard mono-, di- and oligosaccharides of 3-7 DP. Additionally syrup content correlated linearly with the height of the characteristic peak of syrup under different slope in two ranges 2.5-7.5% and 10-100%, respectively. Therefore, the characteristic peak at 15.25 min retention time can serve as a syrup indicator in HPLC analysis of the adulterated honeys. This new HPLC method for honey adulteration detection was further applied in an authenticity inspection on more than 100 commercial honeys. In addition to the improved accuracy of honey adulteration detection, the proposed HPLC method was simple, low cost and easy practice for honey product quality control by government department considering the popularity of HPLC device and technology.

    Full Text Available Palm date fruits have been used for nutritional and medicinal purposes in Middle Eastern countries. They are used in folk medicine for treatment of liver diseases and highly recommended to be consumed by pregnant women before and after delivery. Therefore, the present work aimed to determine the total phenolic content and total flavonoids in three syrups obtained from palm dates extracted with aqueous ethanol (80% and to evaluate in vitro their antioxidative properties. The new findings showed that the three tested syrups contained significantly different amounts of both total phenolic content and total flavonoids. Syrups can be arranged according to the increase of total phenolic contents and total flavonoids as follows: Yemeni-Rotab > Saudi-Tamr > Iraqi-Tamr. The results of antioxidant activities of palm dates syrups obtained by using different in vitro methods were varied depending on the method used. According to the TBARS method, H2O2 scavenging ability and DPPH methods, all syrups showed to have high to very high antioxidant activities. On the other hand, syrups showed low to intermediate antioxidant activities when other methods were used, such as the scavenging ability of ·−OH and NO and the ability to chelate Fe2+ ions. Generally, the values of antioxidant activities of Rotab-syrup have been shown to be always the highest.

    High quality, concentrated sugar syrup crystal is produced in a critical step in cane sugar production: the clarification process. It is characterized by two variables: the color of the produced sugar and its clarity degree. We show that the temporal variations of these variables follow power-law distributions and can be well modeled by multiplicative cascade multifractal processes. These interesting properties suggest that the degradation in color and clarity degree has a system-wide cause. In particular, the cascade multifractal model suggests that the degradation in color and clarity degree can be equivalently accounted for by the initial “impurities” in the sugarcane. Hence, more effective cleaning of the sugarcane before the clarification stage may lead to substantial improvement in the effect of clarification.

    Cranial computed tomography in the initial stage of the intermediate phenotype of maple syrup urine disease (MSUD) demonstrates diffuse, symmetric hypodensities in white and grey matter, which show a complete return to normal after early introduction of an adequate protein-restrictive diet. If diagnosis of this disease is missed or delayed, progressive global (end-stage) atrophy will take place over several years. A decrease in density values correlates well with the total cerebral lipid and water content (closely related to myelinisation), whereas progression and grade of atrophy show a relationship with the severity of pathological white and grey matter changes that are not demonstrable with computed tomography but can be proven histologically. Analysis of both morphological parameters corresponds well with clinical-neurological outcome and therapeutic success. (orig.) [de

    We report the case of a newborn child with maple syrup urine disease (MSUD), diagnosed at 10 days of life. Diffusion-weighted echoplanar MRI showed marked hyperintensity of the cerebellar white matter, the brainstem, the cerebral peduncles, the thalami, the dorsal limb of the internal capsule and the centrum semiovale, while conventional dual-echo sequence evidenced only a weak diffuse T2 hyperintensity in the cerebellar white matter and in the dorsal brainstem. The apparent diffusion coefficient (ADC) of these regions was markedly (>80%) decreased. Therefore, in agreement with current hypotheses on MSUD pathogenesis, MSUD oedema proves to be a cytotoxic oedema. Diffusion-weighted MRI may be a valuable tool, more sensitive than conventional spin-echo techniques, to assess the extent and progression of cytotoxicity in MSUD, as well as the effectiveness of the therapeutic interventions.

    Inborn errors of metabolism (IEMs) are genetic disorders that disrupt enzyme activity, cellular transport, or energy production. They are individually rare but collectively have an incidence of 1:1000. Most patients with IEMs are followed up by a physician with expertise in biochemical genetics (metabolism), but may present outside this setting. Because IEMs can present acutely with life-threatening crises that require specific interventions, it is critical for the emergency medicine physician, pediatrician, internist, and critical care physician as well as the biochemical geneticist to have information on the initial assessment and management of patients with these disorders. Appropriate early care can be lifesaving. This protocol is not designed to replace the expert consultation of a biochemical geneticist, but rather to improve early care and increase the level of comfort of the acute care physician with initial management of maple syrup urine disease until specialty consultation is obtained.

    The pasting and gel textural properties of corn starch in syrup at different concentrations were investigated by Rapid Visco Analyzer (RVA) and Texture profile analysis (TPA) tests. The results showed that the pasting temperatures of corn starch greatly increased, especially at higher sugar concentration. Increasing concentration of syrup caused an increase in peak, trough and final viscosity of corn starch. Peak viscosity and the disintegration rate of starch increased in the following order...

    Honey and agave syrup are high quality natural products and consist of more than 80% sugars. They are used as sweeteners, and are ingredients of cosmetics or medical ointments. Furthermore, both have low water content, are often liquid at room temperature and resemble some known sugar-based deep eutectic solvents (DES). Since it has been shown that it is possible to synthesize sugar esters in these DESs, in the current work honey or, as vegan alternative, agave syrup are used simultaneously a...

    Currently, corn is used to produce more than 85% of the world's high fructose syrup (HFS). There is a search for alternative HFS substrates because of increased food demand and shrinking economies, especially in the developing world. The sweet potato is a feasible, alternative raw material. This study isomerized a high glucose sweet potato starch syrup (SPSS) and determined its sugar profile, mineral content, and rheological and thermal properties. Rheological and thermal properties were measured using a rheometer and DSC, respectively. Sweet potato starch was hydrolyzed to syrup with a mean fructose content of 7.6 ± 0.4%. The SPSS had significantly higher (P syrups. During 70 days of storage, the SPSS acted as a non-Newtonian, shear-thinning liquid in which the viscosity decreased as shear stress increased. Water loss temperature of the SPSS continually decreased during storage, while pancake and ginger syrups' peak water loss temperature decreased initially and then increased. Further and more detailed studies should be designed to further enhance the fructose content of the syrup and observe its stability beyond 70 days. The SPSS has the potential to be used in human food systems in space and on Earth. PMID:26904593

    Sugar maple syrup production is an important economic activity for eastern Canada and the northeastern United States. Since annual variations in syrup yield have been related to climate, there are concerns about the impacts of climatic change on the industry in the upcoming decades. Although the temporal variability of syrup yield has been studied for specific sites on different time scales or for large regions, a model capable of accounting for both temporal and regional differences in yield is still lacking. In the present study, we studied the factors responsible for interregional and interannual variability in maple syrup yield over the 2001-2012 period, by combining the data from 8 Quebec regions (Canada) and 10 U.S. states. The resulting model explained 44.5% of the variability in yield. It includes the effect of climatic conditions that precede the sapflow season (variables from the previous growing season and winter), the effect of climatic conditions during the current sapflow season, and terms accounting for intercountry and temporal variability. Optimal conditions for maple syrup production appear to be spatially restricted by less favourable climate conditions occurring during the growing season in the north, and in the south, by the warmer winter and earlier spring conditions. This suggests that climate change may favor maple syrup production northwards, while southern regions are more likely to be negatively affected by adverse spring conditions.

    The determination of honey authenticity is of importance to ensure its quality and safety. There is an urgent need of effective methods to detect adulterated honey. A simple, rapid, and effective HPLC-DAD method was developed to detect honey adulteration by rice syrup, using a characteristic compound from rice syrup, which is presently difficult to detect by current analytical methods. The characteristic compound was identified as 2-acetylfuran-3-glucopyranoside (AFGP) by MS and NMR. Based on HPLC analyses, the average concentration of AFGP was 92 ± 60 mg/kg in rice syrup. However, AFGP was not detected in any of the natural honey samples, so it could be used as a marker for the detection of honey adulteration by rice syrup. The developed method enabled a rapid detection of honey samples adulterated with 10% rice syrup. Using the developed method, 16 out of 186 honey samples from some markets were found to be adulterated with rice syrup.

    Antioxidant activity, inhibition of nitric oxide (NO) overproduction, and antiproliferative effect of ethyl acetate extracts of maple sap and syrup from 30 producers were evaluated in regard to the period of harvest in three different regions of Québec, Canada. Oxygen radical absorbance capacity (ORAC) values of maple sap and syrup extracts are, respectively, 12 +/- 6 and 15 +/- 5 micromol of Trolox equivalents (TE)/mg. The antioxidant activity was also confirmed by a cell-based assay. The period of harvest has no statistically significant incidence on the antioxidant activity of both extracts. The antioxidant activity of pure maple syrup was also determined using the ORAC assay. Results indicate that the ORAC value of pure maple syrup (8 +/- 2 micromol of TE/mL) is lower than the ORAC value of blueberry juice (24 +/- 1 micromol of TE/mL) but comparable to the ORAC values of strawberry (10.7 +/- 0.4 micromol of TE/mL) and orange (10.8 +/- 0.5 micromol of TE/mL) juices. Maple sap and syrup extracts showed to significantly inhibit lipopolysaccharide-induced NO overproduction in RAW264.7 murine macrophages. Maple syrup extract was significantly more active than maple sap extract, suggesting that the transformation of maple sap into syrup increases NO inhibition activity. The highest NO inhibition induced by the maple syrup extracts was observed at the end of the season. Moreover, darker maple syrup was found to be more active than clear maple syrup, suggesting that some colored oxidized compounds could be responsible in part for the activity. Finally, maple syrup extracts (50% inhibitory concentration = 42 +/- 6 microg/mL) and pure maple syrup possess a selective in vitro antiproliferative activity against cancer cells.

    Agave syrups are gaining popularity as new natural sweeteners. Identification, classification and discrimination by infrared spectroscopy coupled to chemometrics (NIR-MIR-SIMCA-PCA) and HPAEC-PAD of agave syrups from natural sweeteners were achieved. MIR-SIMCA-PCA allowed us to classify the natural sweeteners according to their natural source. Natural syrups exhibited differences in the MIR spectra region 1500-900 cm(-1). The agave syrups displayed strong absorption in the MIR spectra region 1061-1,063 cm(-1), in agreement with their high fructose content. Additionally, MIR-SIMCA-PCA allowed us to differentiate among syrups from different Agave species (Agavetequilana and Agavesalmiana). Thin-layer chromatography and HPAEC-PAD revealed glucose, fructose, and sucrose as the principal carbohydrates in all of the syrups. Oligosaccharide profiles showed that A. tequilana syrups are mainly composed of fructose (>60%) and fructooligosaccharides, while A. salmiana syrups contain more sucrose (28-32%). We conclude that MIR-SIMCA-PCA and HPAEC-PAD can be used to unequivocally identify and classified agave syrups. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Syrup obtained from yacon roots could be well positioned as a nutritional product due to its high fructooligosaccharides (FOS) content. Considering this, we examined the potential food applications of yacon syrup, using the focal group methodology, and its sensorial acceptability when incorporated in yogurt. The beneficial effects of the consumption of yacon syrup were studied over a 2-week period in a double-blind placebo-controlled experiment (namely Test A) and other consistent of only one day of yacon syrup consumption (namely Test B) were also evaluated. The doses of yacon syrup for both experiments were 8.74g of FOS/day. Energy intake, hunger, satiety, fullness and prospective food consumption were assessed with analogue scales at the end of each test. The results indicate that the yogurt was the food most suggested by the focus group, and the average of the scores given to the attributes when the yacon syrup was incorporated into a yogurt were: 7.78 for appearance; 7.72 for aroma; 7.02 for flavor and 6.96 for overall acceptability, corresponding to "like very much" and "like moderately". Furthermore, the results indicate that yacon syrup has a positive effect on appetite and its effect was dependent on gender and period of intervention, being statistically significant (P<0.05) in women, after 2-week period. These findings suggested that increasing FOS intake could help to increase satiety, and consequently, be helpful in the management of type 2-diabetes or control of the current high prevalence of overweight or obesity.

    Full Text Available Background: Hydroxymethylfurfural (HMF is a common Maillard reaction product directly formed from dehydration of sugars under acidic conditions during heating and storage in carbohydrate rich foods. The aim of the present study was to detect and quantify the amount of HMF in date syrup by HPLC method. In addition, the amount of HMF in date syrup produced by traditional and industrial methods were compared. Methods: A HPLC method for determination of HMF in date syrup was developed and validated. The amount of HMF in date syrup products produced by the traditional and industrial methods was compared. In addition, to determine whether HMF was produced during storage in date syrup, its amount was measured in fresh and old samples. Results: The HMF content of fresh traditional products varied between 1000 to 2675 mg⁄kg and in the old products varied between 2580 to 6450 mg⁄kg. The HMF concentration of the fresh industrial products varied between 12 to 456 mg⁄kg and 611 to 943 mg⁄kg in the old ones. The HMF concentration of the traditionally produced products was significantly higher than industrial products (P<0.001. Moreover, the HMF content in old products significantly was more than fresh ones (P<0.001. Wide variation was found in HMF content of the traditionally produced products. Conclusion: HMF was produced in date syrup during preparation and storage. Because HMF is recognized as an indicator of quality deterioration in a wide range of foods and is still under investigation for possible toxic effects, it is recommended that the amount of HMF is measured in date syrup and considered as an indicator of the quality control of this product.

    Full Text Available Phenolic compounds determine the color quality of fruit wines. In this study, the phenolic compound content and composition, color characteristics and changes during 6 months of bottle aging were studied in wines fermented with bog bilberry syrup under three different pHs. The total anthocyanins and total phenols were around 15.12–16.23 mg/L and 475.82 to 486.50 mg GAE/L in fresh wines and declined 22%–31% and about 11% in bottle aged wines, respectively. In fresh wines, eight anthocyanins, six phenolic aids and 14 flavonols, but no flavon-3-ols were identified; Malvidin-3-O-glucoside, petunidin-3-O-glucoside and delphinium-3-O-glucoside were the predominant pigments; Chlorogentic acid was the most abundant phenolic acid, and quercetin-3-O-galactoside and myricetin-3-O-galactoside accounted for nearly 90% of the total flavonols. During 6 months of bottle storage, the amounts of all the monomeric anthocyanins and phenolic acids were reduced dramatically, while the glycosidyl flavonols remained constant or were less reduced and their corresponding aglycones increased a lot. The effects of aging on blueberry wine color were described as the loss of color intensity with a dramatic change in color hue, from initial red-purple up to final red-brick nuances, while the pH of the fermentation matrix was negatively related to the color stability of aged wine.

    Maple syrup urine disease (MSUD) is an autosomal recessive aminoacidopathy secondary to an enzyme defect in the catabolic pathway of the branched-chain amino acids (BCAAs: leucine, isoleucine, and valine). Accumulation of their corresponding keto-acids leads to encephalopathy if not treated in time. A newborn male patient was suspected to have MSUD after tandem mass study when he presented symptoms and signs suggestive neonatal sepsis, anemia, and diarrhea. Food restriction of BCAAs was started; however, acrodermatitis enteropathica-like skin eruptions occurred at age 2 months. The skin rashes resolved after adding BCAAs and adjusting the infant formula. At age 7 months, he suffered from recurrent skin lesions, zinc deficiency, osteoporosis, and kyphosis of the thoracic spine with acute angulation over the T11-T12 level associated with spinal compression and myelopathy. After supplementation of zinc products and pamidronate, skin lesions and osteopenia improved gradually. Direct sequencing of the DBT gene showed a compound heterozygous mutation [4.7 kb deletion and c.650-651insT (L217F or L217fsX223)]. It is unusual that neurodegeneration still developed in this patient despite diet restriction. Additionally, brain and spinal magnetic resonance imaging, bone mineral density study, and monitoring of zinc status are suggested in MSUD patients. Copyright © 2014. Published by Elsevier B.V.

    Abstract Nonmedical use of cough syrup (NUCS) among secondary vocational school (SVS) students has been an increasing concern for public health in China, but no data were available. This cross-sectional study aimed to investigate the epidemiological characters of NUCS as well as its risk factors among SVS students in China. From September 2013 to December 2014, a total of 13,614 SVS students were purposively selected through multistage sampling in 6 cities of China. Information on NUCS, demographics, family background, smoking and alcohol consumption, impulsiveness, sensation seeking, and parental monitoring were collected. Logistic regression was used to explore factors related to NUCS. The 12,923 (94.9%) valid responses (16.3 ± 1.0 years old, and 52.6% men) reported 3.47% (95% confidence interval: 3.15–3.79%) lifetime NUCS. Logistic regression indicated that smoking, part-time job experience, high level of impulsiveness, and sensation seeking were risk factors for NUCS, whereas urban living and high parental monitoring were protective ones. NUCS was prevalent among SVS students. Interventions that target on smoking, impulsiveness and sensation seeking control, improvement on parental monitoring may have considerable impact on NUCS among SVS students. PMID:26962800

    Honey adulteration with sugar syrups is a widespread problem. Several types of syrups have been used in honey adulteration, and there is no available method that can simultaneously detect all of these adulterants. In this study, we generated a small-scale database containing the specific chromatographic and mass spectrometry information on sugar syrup markers and developed a simple, rapid, and effective ultrahigh-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOF-MS) method for the detection of adulterated honey. Corn syrup, high-fructose corn syrup, inverted syrup, and rice syrup were used as honey adulterants; polysaccharides, difructose anhydrides, and 2-acetylfuran-3-glucopyranoside were used as detection markers. The presence of 10% sugar syrup in honey could be easily detected in <30 min using the developed method. The results revealed that UHPLC/Q-TOF-MS was simple and rapid.

    A nitrogen deficiency always causes bog bilberry syrup wine to have a poor sensory feature. This study investigated the effect of nitrogen source addition on volatile compounds during bog bilberry syrup wine fermentation. The syrup was supplemented with 60, 90, 120 or 150 mg/L dibasic ammonium phosphate (DAP) before fermentation. Results showed that an increase of DAP amounts accelerated fermentation rate, increased alcohol content, and decreased sugar level. Total phenol and total flavonoid content were also enhanced with the increase of DAP amounts. A total of 91 volatile compounds were detected in the wine and their concentrations were significantly enhanced with the increase of DAP. Ethyl acetate, isoamyl acetate, phenethyl acetate, ethyl butanoate, ethyl hexanoate, ethyl octanoate, ethyl decanoate, isobutanol, isoamyl alcohol, levo -2,3-butanediol, 2-phenylethanol, meso -2,3-butanediol, isobutyric acid, hexanoic acid, and octanoic acid exhibited a significant increase of their odor activity value (OAV) with the increase of DAP amounts. Bog bilberry syrup wine possessed fruity, fatty, and caramel flavors as its major aroma, whereas a balsamic note was the least present. The increase of DAP amounts significantly improved the global aroma attributes, thereby indicating that DAP supplementation could promote wine fermentation performance and enhance the sensory quality of bog bilberry syrup wine.

    Objectives The aim of the study was to determine the effect of a common clinical practice, the transmucosal (TM) application of corn syrup, on postoperative blood glucose concentrations in kittens. Methods This study was designed as a randomized controlled trial. Seventy-five kittens between the age of 8 and 16 weeks scheduled for surgical sterilization by gonadectomy at an animal shelter were enrolled. Kittens were randomly assigned to either a routine treatment group that received the shelter's typical postoperative application of corn syrup immediately following gonadectomy or to a control group that did not receive typical treatment. Three blood glucose measurements were obtained per kitten: baseline reading prior to preoperative examination, immediately postoperatively and 20 mins postoperatively. The median values of the 20 min postoperative blood glucose reading for the control and treatment groups were compared using the Wilcoxon rank-sum test. Results Postoperative application of corn syrup to the oral mucosa of kittens did not result in significant elevations in blood glucose compared with controls. No kitten was hypoglycemic (⩽60 mg/dl) at any point during the study. Conclusions and relevance TM application of corn syrup did not affect postoperative blood glucose concentrations in kittens. Protocols that use routine TM administration of corn syrup in kittens should be re-evaluated.

    Drying properties of syrup prepared from Parinari curatellifolia fruit and cereal based product, zvambwa prepared from the syrup and finger millet (Eleusine coracana) meal were studied using a convective tray drier at temperatures ranging from 30 to 80 °C and air velocity of 0.72 m/s. Nine mathematical models namely Henderson and Pabis, Lewis, Midilli et al., Modified Page, Page, Two Term, Weibull, Modified Page Equation (II) and Wang and Singh were fitted to data for thin layer drying of the products using non-linear regression analysis. Thin layer drying processes for the syrup and zvambwa were best described by the Modified Page model. Effective moisture diffusivities for drying of syrup were higher than those for drying of zvambwa. The activation energies for drying of syrup and zvambwa were 21.0 ± 2.0 kJ/mol and19.0 ± 2.0 kJ/mol respectively.

    Several flavoring and sweetening agents added to excipient of pediatric syrups are not declared in the package leaflet. Therefore, the aim of this study was to develop a non-target, simple, and precise method for qualitative and quantitative evaluation of pediatric syrups using NMR spectroscopy combined with chemometrics. This approach allowed the identification of several added compounds as citric acid, cyclamate, ethanol, glycerol, propylene glycol, saccharin, sorbitol, fructose, glucose, and sucrose. Among the sugared syrups, sucrose was the main carbohydrate with approximately 59.1%, and for sweetened syrups, glycerol with 25.5%. The ethanol was found with highest concentration of 4.0%, approximately. In addition, some syrups presented both sugar and sweetener, which is inconsistent according to the purpose of the addition. Consequently, institutional structures of countries as Brazil that are in charge of public health should put additional compliance pressure on pharmaceutical companies to clearly declare in package leaflet the presence and exact amount of the main compounds (at least) existent in the pediatric excipients.

    The sorption of 14 aroma compounds into PET and PVC was monitored during storage of a strawberry syrup for 1 year. Concentrations in the syrup and in the polymer were determined during storage and compared with previously published results obtained with glass bottles. Apparent partition coefficients between the polymer and the syrup (noted K app) were estimated from experimental kinetics without reaching equilibrium K app values and optimally identified from the kinetic data obtained between 30 and 90 days. They exhibited a similar behaviour for both polymers with values were between 2 x 10(-5) and 2 x 10(-3), 4 x 10(-5) and 3 x 10(-2), respectively, for PET and PVC. The variation of K app values in PET was mainly correlated to the polarity of tested compounds as assessed by their log P values. By contrast, the variations in K app values for PVC were mainly related to their chain lengths. Due to slightly higher partition coefficients and diffusion coefficients in PVC compared with PET, the amount of absorbed aroma was four times higher in PVC than in PET; however, the amount of absorbed aroma compounds was less than 0.1% of the initial amount present into the syrup, except for octyl butanoate. The variation in concentration in the syrup was interpreted as a combination of a degradation process and a transport process into the packaging material. Both effects were particularly noticeable for both PET and unstable aroma compounds.

    Ondansetron, a highly selective 5-HT3 receptor antagonist, is available in an intravenous (IV) formulation and tables, but syrup would be particularly useful in children. As chemotherapy can affect taste perceptions, this study was undertaken to determine the preference between two flavors of ondansetron syrup in children undergoing chemotherapy. Fifty-nine children, randomized into a multicenter, double-blind, crossover study, each received 5 mg/m2 of IV ondansetron daily before chemotherapy. The syrup was then randomly given in two doses, one of each flavor, strawberry and grape, 30 minutes apart. The preference was assessed 30 minutes after the second dose of syrup had been administered. Taste was assessed by the child against a panel of five faces. Of those children expressing any preference, 70% preferred the strawberry flavor. Overall, 59% of children preferred the strawberry flavor, whilst 25% preferred grape (P = 0.005) and 15% expressed no preference. The only adverse event assessed as drug related by the investigator was constipation, which occurred in one patient. In conclusion, a strong preference was found for the strawberry formulation. The ondansetron syrup was safe and well tolerated.

The results showed that optimized production for a litre of sugar palm syrup medium should compose 15 ºBrix concentration, 7.0 g NH4H2PO4 and 0.7 g MgSO4. 7 H2O at pH 4.25 and incubation at room temperature. The thickness of nata production reached 1.15 cm in 9 days. Sensory evaluation showed that there were no significant difference in odor and acceptability between the nata from sugar palm syrup and the traditional nata production from coconut juice whereas there were significant differences in color and texture. However, the nata from sugar palm syrup gave a better texture. Chemical analysis of the nata produced under these optimal culture conditions revealed 0.13% protein, 0.012% fat, 2.74% fiber, 0.378% nitrogen-free extract, 0.11% ash and 96.63% moisture content. The results suggest that nata produced from sugar palm syrup can be used in food and confectionery.

    Full Text Available Dietary energy for chickens normally includes cereal grains and fat. This innovative study investigated the effect of replacing part of the corn and fat in broiler chicken rations with graded levels of sugar syrup on growth performance and biochemical parameters. Experimental treatments consisted of feeding a corn-soy basal diet alone, or with graded levels of sugar syrup in increments of 5%, 10% and 15%. All starter diets were isonitrogenous and isocaloric. Body weight gain and efficiency of feed utilization of chicks fed the control diet alone were not significantly (P < 0.05 different from chicks fed diets supplemented with either 5% or 15% sugar syrup. Supplementation of sugar syrup to broiler diets had no significant effect on blood glucose, creatinine, total protein, or liver enzymes. Adding 5% sugar syrup to broiler rations significantly decreased blood cholesterol and triglycerides in chickens fed the sugar syrup diet compared with birds fed the control diet. In conclusion, the results shows sugar syrup can be used in poultry ration to replace part of the corn as a source of energy. These results allowed the authors to recommend the safe usage of sugar syrup in broiler rations.

    Maple syrups with selected degree Brix (°Bx) (15, 30, 60) were investigated as reaction systems for levansucrase from Bacillus amyloliquefaciens. The enzymatic conversion of sucrose present in the maple syrup and the production of the transfructosylation products were assessed over a time course of 48h. At 30°C, the use of maple syrup 30°Bx led to the highest levansucrase activity (427.53μmol/mg protein/min), while maple syrup 66°Bx led to the highest converted sucrose concentration (1.53M). In maple syrup 30°Bx, oligolevans (1080%). In maple syrup 66°Bx, the most abundant products were oligolevans at 30°C and levans (DP≥30) at 8°C. The acceptor specificity study revealed the ability of B. amyloliquefaciens levansucrase to synthesize a variety of hetero-fructooligosaccharides (FOSs) in maple syrups 15°Bx and 30°Bx enriched with various disaccharides, with lactose being the preferred fructosyl acceptor. The current study is the first to investigate maple-syrup-based reaction systems for the synthesis of FOSs/oligolevans/levans. Copyright © 2015 Elsevier Ltd. All rights reserved.

    A chemometric analysis of adulteration of Mexican honey by sugar syrups such as corn syrup and cane sugar syrup was realized. Fourier transform infrared spectroscopy (FTIR) was used to measure the absorption of a group of bee honey samples from central region of Mexico. Principal component analysis (PCA) was used to process FTIR spectra to determine the adulteration of bee honey. In addition to that, the content of individual sugars from honey samples: glucose, fructose, sucrose and monosaccharides was determined by using PLS-FTIR analysis validated by HPLC measurements. This analytical methodology which is based in infrared spectroscopy and chemometry can be an alternative technique to characterize and also to determine the purity and authenticity of nutritional products as bee honey and other natural products.

    Full Text Available Leucinosis (maple syrup urine disease - MSUD is an inherited aminoacidopathy and organic aciduria caused by severe enzyme defect in the metabolic pathway of amino acids: leucine, isoleucine, and valine. The classical variant of the disease is characterized by accumulation of both amino and α-keto acids, particulary the most toxic rapid elevation of circulating leucine and its ketoacid, α-ketoisocaproate, which cause encephalopathy and life-threatening brain swelling. However, patients with the most severe form, classical maple syrup urine disease, may appear normal at birth, but develop acute metabolic decompensation within the first weeks of life with typical symptoms: poor feeding, vomiting, poor weight gain, somnolence and burnt sugar-smelling urine, reminiscent of maple syrup. Early diagnosis and dietary intervention improve the patient’s condition, prevent severe complications, and may allow normal intellectual development.

    Constant infusions of [13C]leucine and [2H5]phenylalanine were used to trace leucine and protein kinetics, respectively, in seven children with maple syrup urine disease (MSUD) and eleven controls matched for age and dietary protein intake. Despite significant elevations of plasma leucine (mean 351 mumol/l, range 224-477) in MSUD subjects, mean whole body protein synthesis [3.78 +/- 0.42 (SD) g.kg-1. 24 h-1] and catabolism (4.07 +/- 0.46) were similar to control values (3.69 +/- 0.50 and 4.09 +/- 0.50, respectively). The relationship between phenylalanine and leucine fluxes was also similar in MSUD subjects (mean phenylalanine-leucine flux ratio 0.35 +/- 0.07) and previously reported adult controls (0.33 +/- 0.02). Leucine oxidation was undetectable in four of the MSUD subjects and very low in the other three (less than 4 mumol.kg-1.h-1; controls 13-20). These results show that persistent elevation in leucine concentration has no effect on protein synthesis. The marked disturbance in leucine metabolism in MSUD did not alter the relationship between rates of catabolism of protein to phenylalanine and leucine, which provides further support for the validity of the use of a single amino acid to trace whole body protein metabolism. The minimal leucine oxidation in MSUD differs from findings in other inborn metabolic errors and indicates that in patients with classical MSUD there is no significant route of leucine disposal other than through protein synthesis

    Research on trends in consumption of added sugar and high-fructose corn syrup (HFCS) in the United States has largely focused on calorically sweetened beverages and ignored other sources. We aimed to examine US consumption of added sugar and HFCS to determine long-term trends in availability and intake from beverages and foods. We used 2 estimation techniques and data from the Nationwide Food Consumption Surveys (1965 and 1977), Continuing Survey of Food Intake by Individuals (1989-1991), and the National Health and Nutrition Examination Surveys (1999-2000, 2001-2002, and 2003-2004) to examine trends in HFCS and added sugar both overall and within certain food and beverage groups. Availability and consumption of HFCS and added sugar increased over time until a slight decline between 2000 and 2004. By 2004, HFCS provided roughly 8% of total energy intake compared with total added sugar of 377 kcal x person(-1) x d(-1), accounting for 17% of total energy intake. Although food and beverage trends were similar, soft drinks and fruit drinks provided the most HFCS (158 and 40 kcal x person(-1) x d(-1) in 2004, respectively). Moreover, among the top 20% of individuals, 896 kcal x person(-1) x d(-1) of added sugar was consumed compared with 505 kcal x person(-1) x d(-1) of HFCS. Among consumers, sweetened tea and desserts also represented major contributors of calories from added sugar (>100 kcal x person(-1) x d(-1)). Although increased intake of calories from HFCS is important to examine, the health effect of overall trends in added caloric sweeteners should not be overlooked.

    Full Text Available Important and crucial element in the management of the technological flow of production of sugar product standards is the period of time the enrichment of massecuite, since its neutralization in the process of crystal formation in vacuum apparatus, excess sugar solution. Although currently proposed and implemented in the industry, including as a front-end accompany the process, a number of ways in the real world sugar production in many cases have to resort to the services of an experienced operator. It is obvious that in any case it is necessary to have a surround-dependent glucose solution data on time for the excess sugar solution into the vacuum apparatus. With regard to the period of the enrichment of depleted sucrose solution are entered into this substance excess sucrose solution, it should be noted that this problem is theoretically still insufficiently developed. It is obvious that for practical purposes it is desirable to have a simple and convenient for engineering calculation of sugar processing time dependencies of the specified volume of water from the operating parameters of the process (the required concentration of sucrose, temperature of the solution stirring. The problem is the quantitative analysis of sucrose crystallization in vacuum apparatus, including the timing of enrichment solution to the excess syrup, period of time processing massecuite total this apparatus has been investigated in many works. However, due to its importance to the task of obtaining commercial sugar high standards this issue required further in-depth examination. In the article to support the enrichment process solution sucrose due to neutralize this solvent system in vacuum apparatus, from the standpoint of diffusion theory provides a more reasonable compared to known so far, quantitative analysis of this process. Where as sucrose crystals team are considering a system of balls, uniformly distributed in vacuum apparatus. On the basis of the solution

    2014-01-01

    BACKGROUND: Acute otitis media (AOM) is a common childhood illness and the leading indication for antibiotic prescriptions for US children. Xylitol, a naturally occurring sugar alcohol, can reduce AOM when given 5 times per day as a gum or syrup, but a more convenient dosing regimen is needed for widespread adoption. METHODS: We designed a pragmatic practice-based randomized controlled trial to determine if viscous xylitol solution at a dose of 5 g 3 times per day could reduce the occurrence of clinically diagnosed AOM among otitis-prone children 6 months through 5 years of age. RESULTS: A total of 326 subjects were enrolled, with 160 allocated to xylitol and 166 to placebo. In the primary analysis of time to first clinically diagnosed AOM episode, the hazard ratio for xylitol versus placebo recipients was 0.88 (95% confidence interval [CI] 0.61 to 1.3). In secondary analyses, the incidence of AOM was 0.53 episodes per 90 days in the xylitol group versus 0.59 in the placebo group (difference 0.06; 95% CI –0.25 to 0.13); total antibiotic use was 6.8 days per 90 days in the xylitol group versus 6.4 in the placebo group (difference 0.4; 95% CI –1.8 to 2.7). The lack of effectiveness was not explained by nonadherence to treatment, as the hazard ratio for those taking nearly all assigned xylitol compared with those taking none was 0.93 (95% CI 0.56 to 1.57). CONCLUSIONS: Viscous xylitol solution in a dose of 5 g 3 times per day was ineffective in reducing clinically diagnosed AOM among otitis-prone children. PMID:24394686

    Maple syrup is a high value artisanal product produced mainly in Canada and a number of States primarily in the northeast USA. Mold growth (Wallemia sebi) on commercial product was first reported in syrup in 1908. Since then, few data have been published. We conducted a systematic examination for fungi in maple syrup from 68 producers from all of the syrup-producing areas of Ontario, Canada. The mean pH of the samples was pH 6.82, sugar content averaged 68.0±0.89 °Brix and aw averaged 0.841±0.011. Some 23 species of fungi were isolated based on morphology and molecular techniques. The most common fungus in the maple syrup samples was Eurotium herbariorum, followed by Penicillium chrysogenum, Aspergillus penicillioides, Aspergillus restrictus, Aspergillus versicolor and two species of Wallemia. Cladosporium cladosporioides was also common but only recovered when fungi known from high sugar substrates were also present in the mold damaged sample. The rarely reported yeast Citeromyces matrinsis was found in samples from three producers. There appear to be three potential causes for mold damage observed. High aw was associated with about one third of the mold damage. Independently, cold packing (bottling at ~25 °C) was a risk factor. However, syrup of good quality and quite low aw values was contaminated. We hypothesize that sanitation in the bottling line and other aspects of the bottling process may be partial explanations. Clarifying this requires further study. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Available tablets or capsules for adults are often used to prepare extemporaneously formulated medicines appropriate for children. The most acceptable drug forms in pediatric population are oral liquids and pharmacists use commercial dispersing media to compound syrups from an active substance or from tablets available on the market. In many countries ready-to-use dispersing media are not available or refunded, but pharmacists can use other compounded media, providing their compatibility and stability are proven. The aim of this study was to formulate and evaluate the stability of syrups with candesartan cilexetil (1 mg mL-1 and valsartan (4 mg mL-1 extemporaneously prepared using commercial tablets (Diovan® and Atacand®. The following three different suspending media, which could be easily made in a pharmacy, were investigated: V1 - with xanthan gum (0.5 %, V2 - the USP/NF vehicle for oral solution and V3 - the medium based on a simple sucrose syrup. The stability of preparations was studied during 35 days of storage in a dark place at controlled temperature of 25 and 4 °C. During the study, microscopic observation was carried out and pH, viscosity, and concentration of candesartan cilexetil and valsartan were analyzed. Syrups with valsartan prepared with V2 and V3 media were stable for 3 or 4 weeks when stored at 25 °C, while syrups with candesartan were stable for as long as 35 days. For syrups prepared using V1 medium, the 14-day expiry date was not achieved because of microbial deterioration.

    Full Text Available Honey and agave syrup are high quality natural products and consist of more than 80% sugars. They are used as sweeteners, and are ingredients of cosmetics or medical ointments. Furthermore, both have low water content, are often liquid at room temperature and resemble some known sugar-based deep eutectic solvents (DES. Since it has been shown that it is possible to synthesize sugar esters in these DESs, in the current work honey or, as vegan alternative, agave syrup are used simultaneously as solvent and substrate for the enzymatic sugar ester production. For this purpose, important characteristics of the herein used honey and agave syrup were determined and compared with other available types. Subsequently, an enzymatic transesterification of four fatty acid vinyl esters was accomplished in ordinary honey and agave syrup. Notwithstanding of the high water content for transesterification reactions of the solvent, the successful sugar ester formation was proved by thin-layer chromatography (TLC and compared to a sugar ester which was synthesized in a conventional DES. For a clear verification of the sugar esters, mass determinations by ESI-Q-ToF experiments and a NMR analysis were done. These environmentally friendly produced sugar esters have the potential to be used in cosmetics or pharmaceuticals, or to enhance their effectiveness.

    Migraine is one of the most common and debilitating neurological problems. Although numerous preventive drugs are used to treat migraine, their complications are unavoidable. Application of herbal medicine, especially well-known medicinal plants, to treatment of chronic diseases, like migraine, could be effective. Coriandrum sativum L. (C. sativum) fruit is one of the most commonly prescribed herbs in Persian medicine, which has been used to treat headache. This study was designed to evaluate the effects of C. sativum syrup on duration, severity and frequency of migraine. A total of 68 migraineurs, who had the eligibility criteria, according to international headache society diagnostic criteria, were randomly assigned to intervention group (n = 34) or control group (n = 34). In addition to 500 mg of sodium valproate per day, in intervention group, they received 15 mL of Coriander fruit syrup and 15 mL of placebo syrup, in control group, three times a day, during a month. The subjects were followed for clinical efficacy at weeks 1, 2, 3 and 4. The number of migraine attacks per week, as well as the duration and severity of attacks, were evaluated. Of 68 patients randomized, 66 were included in analysis. The generalized estimating equations analysis showed that the Coriander fruit syrup decreased duration, severity and frequency of migraine, in the intervention group (P sativum fruit is efficient in reduction of the duration and frequency of migraine attacks and in diminishing pain degree.

    2013-10-01

    Maple syrup has high maket value. It is produced in North East America from the heat-evaporated sap of Acer saccharum Marshall. For marketing purposes, there is interest in defining its flavour profile in a consistent and repeatable manner. An experiment was undertaken to explore the potential of autofluorescence of maple syrup induced at 275 and 360 nm to characterise flavours. A mixed data factor analysis revealed two independent groups of variables. One represents early season woody and late season empyreumatic flavours. The other is related to off-flavour, confectionery and maple flavours. Maple and confectionery flavours are subtle, difficult to distinguish and opposed to off-flavour. There were clear relationships among the two groups and fluorescence profiles. For each of the five basic flavours, discriminant models based on partial least squares regressions were developed. For each sample of syrup, flavours combined to form flavour profiles, and the results from the five discriminant models were aggregated to reproduce these profiles. For excitation at 275 nm, the woody/off-flavour and confectionery/empyreumatic/maple flavour profiles were classified correctly 86 and 78% of the time (cross-validation) respectively. Induced autofluorescence spectra were shown to contain information related to maple syrup flavours. This fluorescence-flavour relationship is not considered quantitative yet, and further research avenues are proposed. © 2013 Society of Chemical Industry.

    Maple syrup has nutraceutical potential given the macronutrients (carbohydrates, primarily sucrose), micronutrients (minerals and vitamins), and phytochemicals (primarily phenolics) found in this natural sweetener. We conducted compositional (ash, fiber, carbohydrates, minerals, amino acids, organic acids, vitamins, phytochemicals), in vitro biological, and in vivo safety (animal toxicity) studies on maple syrup extracts (MSX-1 and MSX-2) derived from two declassified maple syrup samples. Along with macronutrient and micronutrient quantification, thirty-three phytochemicals were identified (by HPLC-DAD), and nine phytochemicals, including two new compounds, were isolated and identified (by NMR) from MSX. At doses of up to 1000 mg/kg/day, MSX was well tolerated with no signs of overt toxicity in rats. MSX showed antioxidant (2,2-diphenyl-1-picrylhydrazyl (DPPH) assay) and anti-inflammatory (in RAW 264.7 macrophages) effects and inhibited glucose consumption (by HepG2 cells) in vitro. Thus, MSX should be further investigated for potential nutraceutical applications given its similarity in chemical composition to pure maple syrup. PMID:24983789

    At present, the rice syrup as a low price of the sweeteners was often adulterated into acacia honey and the adulterated honeys were sold in honey markets, while there is no suitable and fast method to identify honey adulterated with rice syrup. In this study, Near infrared spectroscopy (NIR) combined with chemometric methods were used to discriminate authenticity of honey. 20 unprocessed acacia honey samples from the different honey producing areas, mixed? with different proportion of rice syrup, were prepared of seven different concentration gradient? including 121 samples. The near infrared spectrum (NIR) instrument and spectrum processing software have been applied in the? spectrum? scanning and data conversion on adulterant samples, respectively. Then it was analyzed by Principal component analysis (PCA) and canonical discriminant analysis methods in order to discriminating adulterated honey. The results showed that after principal components analysis, the first two principal components accounted for 97.23% of total variation, but the regionalism of the score plot of the first two PCs was not obvious, so the canonical discriminant analysis was used to make the further discrimination, all samples had been discriminated correctly, the first two discriminant functions accounted for 91.6% among the six canonical discriminant functions, Then the different concentration of adulterant samples can be discriminated correctly, it illustrate that canonical discriminant analysis method combined with NIR spectroscopy is not only feasible but also practical for rapid and effective discriminate of the rice syrup adulterant of acacia honey.

    Full Text Available The structural properties of mixtures with pectin, oxidised starch and glucose syrup were investigated using small deformation dynamic oscillation. The composition of the mixture, pH and temperature course of analysis were designed to imitate the development of confectionery products. In the absence of added calcium, preparations of low methoxy pectin with glucose syrup form viscous solutions, which remain crystal-free at subzero temperatures. Samples of oxidised starch and glucose syrup. on the other hand, exhibit solid-like behavior due to the crystalline nature of the amylose-like helices. Mixtures of the two polyssacharides with the co-solute show clearly the phase inversion from liquid to solid-like behavior with increasing amounts of starch in the formulation. The transformation is reflected in the textural properties of samples which vary from thick solutions to firm gels. The viscoelasticity of the system can be modified further by the introduction of high methoxy pectin. 1hus preparations of high methoxy pectin and glucose syrup form rubbery gels whose amorphous nature undergoes a glass transition during cooling. The energetic requirement for the formation of the biological rubber was in good agreement with corresponding data in the literature.

    2001-08-01

    The effects of sweetening agents on the quality of low sweetened jams were compared with respect to blackcurrant, raspberry, sour cherry, strawberry, and bilberry jams. The sweetening agents were sucrose, aronia berry honey syrup, and sucrose + honey syrup at a ratio of 1:1. The level of physicochemical indices, especially the content of vitamin C and anthocyanins determined directly after production and after 3- and 6-month storage, was used as the quality criterion for the evaluation of jams. Moreover, after 6-month storage the products were subjected to sensorial analysis. According to the accepted method of the investigation the produced jams were characterized by a 32-33% content of extract. During the production and 6-month storage the content of acids slightly and that of pectin considerably (from 26 to 46%) decreased, although the consistency of the jams was not affected thereby. In the case of vitamin C, its pronounced losses concerned raspberry (62-67% of the initial value), strawberry (57-61%), and sour cherry (57-58%), being distinctly smaller in blackcurrant (13-16%) and bilberry (15-35%) jams. With respect to anthocyanins a similar regularity was observed, the losses reaching 49-63% in strawberry jam, 40-56% in raspberry, 33-39% in sour cherry, 30-36% in blackcurrant, and 28-36% in bilberries. In almost all the products the losses of vitamin C and anthocyanins were higher when sweetening agent was aronia berry honey syrup. The organoleptic evaluation showed that the addition of aronia berry honey syrup to raspberry and strawberry jams slightly spoiled their colour but improved the aroma and taste. In the final score the significant differentiation in favour of the addition of aronia berry honey syrup concerned only blackcurrant, sour cherry, and bilberry jams.

    Sweet potato has been chosen as one of NASA's crops to support human beings in future space missions. One of the possible uses is to make syrup that can be used as a general sweetener. In this work a simple engineering system for converting sweet potato starch into glucose syrup was studied on a laboratory scale. The system comprises the following main units: a blender, continuous stirred tank reactor (CSTR), centrifugal and vacuum filters, deionization column and vacuum evaporator. The system was tested by carrying out conversion processes from fresh sweet potato roots. The roots were pealed, sliced, homogenized, heated and hydrolyzed by diastase of malt and Dextrozyme C (Novo Nordisk BioChem, North America, Inc.) enzymes in the CSTR. After hydrolysis the slurry was filtered, de-ionized and concentrated to get glucose syrup. The performance of the system was evaluated based on the quality of the conversion. The main factor was the level of reducing sugars except for the deionization where ash content and color were the main factors. Through careful control of the system units, good heating performance in the CSTR was obtained and the hydrolysis process attained sufficient conversion. The filtration process that incorporated the centrifuge was faster than when it was by-passed to the vacuum filter but losses in sugars were higher. Deionization removed more than 90% of the ash and reduced pigmentation, with probable insignificant losses in sugars during the deionization process. Recovery levels when the centrifuge was used and when it was by-passed could reach about 65% and 78%, respectively. These correspond to reducing sugar concentration of 259 and 310 mg/ml in 150-ml syrups from 300 g of sweet potatoes in each process. However, from concentration trials, syrups with volumes of 100 and 70 ml with the respective dextrose equivalence of 281 and 213 mg/ml were obtained. The syrups obtained were brownish in color and the process that employed centrifugal filtration

    To evaluate acceptability of 2 mm solid dosage forms (mini-tablets) as an alternative administration modality in young children in comparison with syrup. Three hundred six pediatric in- and outpatients aged 6 months-5 years (51 in each of 6 age groups) were recruited. An open, randomized cross-over study was conducted to compare acceptability and capability to swallow 2 mm uncoated or coated mini-tablets vs 3 mL syrup. In the overall patient population of 306 children, the acceptability of uncoated mini-tablets was superior to syrup (difference in proportions 14.8%, 95% CI 10.2-19.4; P syrup as well (difference in proportions 12.3%, 95% CI 5.4-19.3; P = .0008). All 3 pharmaceutical formulations were well tolerated, and none of the 306 children inhaled or coughed because of the syrup or the uncoated mini-tablet; only 2 of the 306 children (both in age group 0.5-1 year) coughed because of the coated mini-tablet, in both cases without clinical relevance. Mini-tablets are a valuable alternative to syrup for children 6 months-6 years of age and are more acceptable compared with liquid formulation. Regulatory bodies such as Food and Drug Administration and European Medicine Agency are encouraged to take our data into account for guideline updates and future drug approval processes.

    The primary objective of this study was to compare the bioavailability of paracetamol, phenylephrine hydrochloride and guaifenesin in a new oral syrup with an established oral reference product. The secondary objective was to compare the safety of the new syrup and the reference product. This was a single-centre, open-label, randomized, reference-replicated, crossover study. Healthy adult volunteers received one dose of syrup and two separate doses of a reference oral liquid formulation in a randomized sequence over three study periods, with a washout interval of ≥ 7 days between study periods. Blood samples were taken regularly postdose and analysed for paracetamol, phenylephrine hydrochloride and guaifenesin concentrations; adverse events were recorded. This study enrolled 45 subjects. For paracetamol and guaifenesin, the syrup and reference product were considered to be bioequivalent. Bioequivalence was not shown for phenylephrine hydrochloride. All adverse events were mild or moderate, most of which were considered formulation related. The syrup did not reach bioequivalence with the reference product, as bioequivalence could not be shown for phenylephrine hydrochloride. This may be due to differences in the excipients between the two products. Both the syrup and the reference product had a good safety profile and were well tolerated.

    This study was performed to establish a method that can quickly and accurately identify adulterated syrup in the pure pineapple juice. A attenuated total internal refraction-fourier transform infrared spectroscopy was used to collect the range of 900 -1 500 cm(-1) infrared spectra of 234 samples pure pineapple juice and adulterated syrup by beet syrup, rice syrup and cassava syrup. By using linear discriminant analysis and support vector machine for the identification model, comparing the full spectral and selected wavelengths based on principal component analysis loading plots of the two models to identify adulteration. Studies showed that the correct rate of validation set by linear discriminant analysis and support vector machine model on full spectral were both higher than 88%, variables were significantly reduced from 312 to 8 after selecting the eight characteristic wavelengths, the correct rate of validation set by linear discriminant analysis model was up to 96.15% and support vector machine was increase to 94.87%. The results demonstrated that the model built using a attenuated total internal refraction-fourier transform infrared spectroscopy in combination with chemometric methods after selected characteristic wavelengths could be used for the identification of the adulterated syrup in the pure pineapple juice.

    Using localized proton magnetic resonance spectroscopy ( 1 H-MRS), accumulation of branchedchain amino acids (BCAA) and their corresponding 2-oxo acids (BCOA) could be non-invasively demonstrated in the brain of a 9-year-old girl suffering from classical maple syrup urine disease. During acute metabolic decompensation, the compounds caused a signal at a chemical shift of 0.9 ppm which was assigned by in vitro experiments. The brain tissue concentration of the sum of BCAA and BCOA could be estimated as 0.9 mmol/l. Localized 1 H-MRS of the brain appears to be suitable for examining patients suffering from maple syrup urine disease in different metabolic states. (orig.)

    Different types of packaging (glass bottle, PVC, and PET) were compared for the preservation of aroma quality of a strawberry syrup during shelf life. Esters, alcohols, and aldehydes were analyzed by solid-phase micro-extraction (SPME) and solvent extraction. During storage, hydrolysis of esters in acids and alcohols led to a modification of the aroma profile which can be explained by the replacement of "fruity" and "fresh" notes by "dairy note" in the syrup. Aroma compounds that are responsible for fruity notes, such as methyl cinnamate, methyl anthranilate, and methyl dihydrojasmonate, were strongly reduced after 90 days. This could be explained by a selective interaction of these compounds with the polymer matrix (PET or PVC). After 330 days, a later and important decrease of the "fruity notes" occurred in both PETs; so PVC2 and the glass bottle were found to be able to maintain a balanced aroma for long-term storage.

    2018-04-03

    The consumption of natural and low calorie sugars has increased enormously from the past few decades. To fulfil the demands, the production of healthy sweeteners as an alternative to sucrose has recently received considerable interest. Fructose is the most health beneficial and safest sugar amongst them. It is generally recognised as safe (GRAS) and has become an important food ingredient due its sweetening and various health promising functional properties. Commercially, high fructose syrup is prepared from starch by multienzymatic process. Single-step enzymatic hydrolysis of inulin using inulinase has emerged as an alternate to the conventional approach to reduce complexity, time and cost. The present review, outlines the enzymatic strategies used for the preparation of high fructose syrup from inulin/inulin-rich plant materials in batch and continuous systems, and its conclusions.

    The chemical stability of hydrocortisone in two different commercially available vehicles for compounding oral liquid dosage forms has been studies using a stability-indicating high-performance liquid chromatographic assay method that was developed in our laboratory. Hydrocortisone was more stable in Ora-Sweet vehicle than in Humco simple syrup. After 71 days of storage at 60 degrees Celsius, the percent of hydrocortisone retained in Humco simple syrup was 62.8 ( initial pH value of the dosage form was 5.2) versus 67.7 in Ora-Sweet vehicle (initial pH value of the dosage form was 4.3). Due to the hydrolysis of sugar, the physical appearances of both the dosage forms gradually changed from almost colorless to yellow. Citric acid, which was present only in the Ora-Sweet vehicle, did not adversely affect the stability of hydrocortisone.

    The impact of honey or vinegar on several metabolic abnormalities has been studied separately, a mixture of these two ingredients known as honey vinegar syrup (HVS) has not been investigated previously so far. The aim of this study was to assess the impact of HVS consumption (Iranian's traditional syrup) on glycemic parameters and lipid profiles in healthy individuals. We conducted a 4-week, randomized, controlled, parallel study consisting of two groups of nonobese healthy volunteers. All subjects were asked to stay on their normal diet. Intervention group (n = 36) received a cup of HVS daily in the evening snack for 4-week (250 cc syrup contains 21.66 g honey vinegar). Assessments of fasting blood sugar (FBS), insulin, homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were conducted at the baseline and after 4-week of study. We observed no significant effect of HVS on FBS, HOMA-IR, LDL-C and TG. A significant effect of HVS was found on increasing fasting insulin and HOMA-IR and reduction in TC level only in intervention group (Δ =3.39 P = 0.01, Δ =1.65 P = 0.03, Δ = -9.43 P = 0.005, respectively). Changes of FBS, TG and LDL-C were 1.83 mg/dl, -1.53 mg/dl and - 3.99 mg/dl respectively in the intervention group. These changes were not significant. An unfavorable and significant reduction in HDL-C level was also observed between two groups (Δ = -4.82 P syrup increased fasting insulin level and decreased TC level in the intervention group. HVS had an unfavorable effect on HDL-C level. Further prospective investigations are warranted to confirm these findings.

    Patients undergoing methadone maintenance treatment self-report enhanced preferences for, and excessive consumption of, foods rich in sugar. However, it is unclear whether these are direct pharmacological effects of methadone or the consequences of metabolic dysfunctions induced by addiction to illicit opiates. Hence, the current study in drug-naïve male Sprague-Dawley rats explored the effects of steady-state methadone delivered by osmotic mini-pumps (13 days; 0, 10, 30 mg/kg/day) on consumption of rat chow and a palatable, sweet, liquid high fructose corn syrup solution. Six days after the removal of the pumps, mRNA expression of genes involved in responses to stress and rewards were quantified: pro-opiomelanocortin in the hypothalamus, mu-opioid receptor in the nucleus accumbens, and dopamine D2 receptor in the dorsal striatum. Taste reactivity and locomotion tests were also performed throughout the study. It was found that methadone increased caloric intake from high fructose corn syrup and reduced caloric intake from chow, effects that could not be directly ascribed to changes in high fructose corn syrup taste reactivity or motor functions. However, the changes in caloric intake displayed significant tolerance, and mRNA expression analysis suggested that methadone attenuated the effect of high fructose corn syrup on pro-opiomelanocortin mRNA, and possibly on dopamine D2 receptor mRNA. These findings in rats suggest that the pharmacological effect of methadone, administered to achieve steady-state maintenance, may not be the primary cause of dietary alterations reported by patients maintained on methadone.

    Three α-ketoaldehydes, potentially present in high fructose agave syrups (HFASs) as intermediates of the Maillard reaction, were determined. A previously reported HPLC-FLD procedure based on pre-column derivatisation with 4-methoxy-o-phenylenediamine was adopted, yielding the method quantification limits 0.11 mg/kg, 0.10mg/kg, 0.09 mg/kg for glyoxal, methylglyoxal (MGo) and diacetyl, respectively. The obtained results revealed high concentrations of methylglyoxal in HFASs (average 102 ± 91 mg/kg, range 15.6-315 mg/kg) as compared to commercial Mexican bee honeys or corn syrups. Hydrogen peroxide was generated in all HFASs upon dilution, yet to less extent than in bee honeys. HFASs presented bacteriostatic activity against Bacillus subtilis and Escherichia coli; catalase addition had minimum effect on the assay results in syrups with elevated MGo. Principal component analysis revealed direct association between growth inhibition and MGo. It is concluded that elevated concentration of MGo in HFASs is at least in part responsible for their non-peroxide bacteriostatic activity. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2017-01-01

    Chocolate milk is one of the most commonly used non-fermentative dairy products, which, due to high level of sucrose, could lead to diabetes and tooth decay among children. Therefore, it is important to replace sucrose with other types of sweeteners, especially, natural ones. In this research, response surface methodology (RSM) was used to optimize the ingredients formulation of prebiotic chocolate milk, date syrup as sweetener (4-10%w/w), inulin as prebiotic texturizer (0-0.5%w/w) and carrageenan as thickening agent (0-0.04%w/w) in the formulation of chocolate milk. The fitted models to predict the variables of selected responses such as pH, viscosity, total solid, sedimentation and overall acceptability of chocolate milk showed a high coefficient of determination. The independent effect of carrageenan was the most effective parameter which led to pH and sedimentation decrease but increased viscosity. Moreover, in most treatments, date syrup and inulin variables had significant effects which had a mutual impact. Optimization of the variables, based on the responses surface 3D plots showed that the sample containing 0.48% (w/w) of inulin, 0.04% (w/w) of carrageenan, and 10% of date syrup was selected as the optimum condition.

    Full Text Available In order to develop methods for preserving fruit and berry syrup, which exclude the use of high-temperature sterilization and preservatives, the survival of spores of micromycetes (B. nivea molds in model media with different concentration of food osmotically active substances (sucrose, ethyl alcohol, citric acid at a certain concentration of lethal effects on microorganisms. It has been established that model media (juice based syrups from blueberries with a mass content of 4 % and 6 % alcohol, 50 % sucrose, 1 % and 2 % titrated acids, have a lethal effect on spores of B. nivea molds. The regression equation is obtained expressing the dependence of the amount of spores of B. nivea molds on the concentration of sucrose, acid, alcohol and the storage time of syrups. The form of the dependence and direction of the connection between the variables is established – a negative linear regression, which is expressed in the uniform decrease of the function. The estimation of quality of the received regression model is defined. The deviations of the calculated data from the data of the initial set are calculated. The proposed model has sufficient reliability, since the regression function is defined, interpreted and justified, and the estimation of the accuracy of the regression analysis meets the requirements.

  20. Alternatives for clarifying glucose syrup obtained by enzymatic hydrolysis of starch

    2004-05-01

    Full Text Available The present paper studies some routes for separating and purifying glucose syrup obtained by enzymatic hydrolysis of potato starch. The clarifying process is done in three stages. The first one (solids remotion is done by applying conventional solid-liquid separation techniiques such as sedimentation, centrifugation and filtration, as well as studying the effect of using flocculant and coagulant agents, prior to the already mentioned operations. Purification is done by adding decolouring agents, followed by ultrafiltration of the syrup. The last step (concentration is done by vacuum evaporation. The results showed that separation, centrifuging and sedimation reached 50% yield whilst filtration and ultrafiltration achieved 78% and 98% respectively. It was found that adsorbent agents such as activated carbon and diatomaceous earth were effective in removing colour during the purification stage. The most suitable alternative for separation can be suggested from the foregoing, allowing a syrup to be obtained having similar characteristics and propierties to the commercial product. The most appropriate technological module for carrying out the operation is also represented.

    We compared a new coated-particle formulation of valproate (Depakote Sprinkle) capsules with valproic acid (Depakene) syrup for bioavailability, side effects, and patient and parent preference. Twelve children with epilepsy, aged 5 to 16 years, participated in this randomized, two-period, crossover study. They were assigned to a 7-day regimen with one formulation and then crossed over to the other; the drug was given every 12 hours. On day 7, blood samples collected during a 12-hour period were analyzed for the presence of valproate. At the study's end, parents and children were asked structured questions regarding formulation preference and adverse events. The extent of absorption from sprinkle equaled that from syrup (relative bioavailability = 1.02), but absorption was slower (time to maximum concentration = 4.2 vs 0.9 hour; p less than 0.01). Fluctuations in serum concentrations were less with sprinkle (34.8% vs 62.3%; p less than 0.01). Sprinkle was preferred by 9 of the 12 parents because of east of administration, and by nine of the children because of improved palatability. We conclude that sprinkle may be substituted for syrup without changing the daily dose. Furthermore, sprinkle, because of its prolonged absorption, may be given every 12 hours to children receiving monotherapy. Compliance may be enhanced because of the more convenient dosing schedules and the high degree of patient and parent acceptance.

    Near-infrared spectroscopy (NIR) was used for qualitative and quantitative detection of honey adulterated with high-fructose corn syrup (HFCS) or maltose syrup (MS). Competitive adaptive reweighted sampling (CARS) was employed to select key variables. Partial least squares linear discriminant analysis (PLS-LDA) was adopted to classify the adulterated honey samples. The CARS-PLS-LDA models showed an accuracy of 86.3% (honey vs. adulterated honey with HFCS) and 96.1% (honey vs. adulterated honey with MS), respectively. PLS regression (PLSR) was used to predict the extent of adulteration in the honeys. The results showed that NIR combined with PLSR could not be used to quantify adulteration with HFCS, but could be used to quantify adulteration with MS: coefficient (R p 2 ) and root mean square of prediction (RMSEP) were 0.901 and 4.041 for MS-adulterated samples from different floral origins, and 0.981 and 1.786 for MS-adulterated samples from the same floral origin (Brassica spp.), respectively.

    Ingestion of high-fructose corn syrup (HFCS) is associated with the risk of both diabetes and obesity. Rare sugar syrup (RSS) has been developed by alkaline isomerization of HFCS and has anti-obesity and anti-diabetic effects. However, the influence of RSS on glucose metabolism has not been explored. We investigated whether long-term administration of RSS maintains glucose tolerance and whether the underlying mechanism involves hepatic glucokinase translocation. Wistar rats were administered water, RSS, or HFCS in drinking water for 10 weeks and then evaluated for glucose tolerance, insulin tolerance, liver glycogen content, and subcellular distribution of liver glucokinase. RSS significantly suppressed body weight gain and abdominal fat mass (p < 0.05). The glucose tolerance test revealed significantly higher blood glucose levels in the HFCS group compared to the water group, whereas the RSS group had significantly lower blood glucose levels from 90 to 180 min (p < 0.05). At 30, 60, and 90 min, the levels of insulin in the RSS group were significantly lower than those in the water group (p < 0.05). The amount of hepatic glycogen was more than 3 times higher in the RSS group than that in the other groups. After glucose loading, the nuclear export of glucokinase was significantly increased in the RSS group compared to the water group. These results imply that RSS maintains glucose tolerance and insulin sensitivity, at least partly, by enhancing nuclear export of hepatic glucokinase.

    In Persian ethnomedicine several herbal remedies and functional foods have been used to treat migraine headache which are mostly summarized in Qarabadin-e-kabir (Aghili-Shirazi MH, 1773). One of them is Citron syrup (Sharbat-e-Balang) containing edible Citrus medica L. fruit juice and sugar. The present study was designed to assess the efficacy and safety of Citron syrup on patients with migraine headache. Citron syrup was prepared as described in Qarabadin-e-kabir. In this double blind randomized placebo-controlled clinical trial, ninety patients with migraine headache were allocated to three parallel groups (Citron syrup, propranolol or placebo). Patients received 15ml of Citron syrup, placebo syrup or 20mg of propranolol tablet three times daily after a meal for 4 weeks. Primary outcomes were obtained from three measures: the frequency (per month), mean duration (hour) and mean intensity (visual analogue scale "VAS" 0-10 score) of headache attacks evaluated prior to and following 4 weeks of the intervention. Citron syrup was superior to placebo in reduction of headache attacks intensity (P0.05). However, unlike propranolol, Citron syrup could not significantly reduce the frequency of attacks compared to placebo. No indication of any serious side effects from Citron syrup was observed. According to obtained results, Citron syrup as a traditional Persian remedy can be suggested as an effective treatment for decreasing pain intensity and duration of attacks in migraine headache and the effectiveness is comparable to propranolol. However, the syrup did not show significant effect on frequency of attacks. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  7. A Review of the Ingredients Contained in Over the Counter (OTC Cough Syrup Formulations in Kenya. Are They Harmful to Infants?

    Directory of Open Access Journals (Sweden)

    Gabriel Kigen

    Full Text Available Cough syrups are widely used in the developing world, but safety of their use in infants and children less than two years has not been well documented. Some syrups contain multiple combinations of such drugs as promethazine, diphenhydramine and ephedrine; which are individually now contraindicated in children less than two years. Despite this, the syrups are available as over the counter drugs and may be dispensed to mothers who are unaware of the potentially hazardous effects to their infants. A descriptive cross-sectional study was used to investigate suitability of cough syrups sold within Eldoret municipality for use in children less than two years of age based on their formulations and available literature.Two semi-structured questionnaires were administered to pharmacy attendants and mothers attending sick child clinic at a referral hospital to establish whether cough syrups containing more than one active ingredient of compounds, now contraindicated in children are administered to infants, and awareness of potential serious adverse effects. Data from labeled contents of cough syrups from retail pharmacies was recorded and corroborated with information from literature to determine those deemed to contain the ingredients. The second questionnaire was administered to mothers with children less than two years to ascertain whether they had used the identified syrups. A total of 260 mothers and 55 pharmacy attendants were interviewed.There was widespread use of the syrups in children, including infants, with 192 (74% of the respondents having used identified syrups and over 90% of these on children less than 2 years including those less than three months.146 (76% mothers had administered the syrup at double the recommended dose.The regulatory authorities should make concerted efforts to discourage use of cough syrups containing ingredients that pose adverse events to infants, including campaigns to educate pharmacy workers and mothers.

    A plastic tubing system operated under vacuum is usually used to collect sap from maple trees during spring time to produce maple syrup. This system is commonly sanitized with isopropyl alcohol (IPA) to remove microbial contamination colonizing the system during the sugar season. Questions have been raised whether IPA would contribute to the leaching of plastic residues in maple sap and syrup coming from sanitized systems. First, an extraction experiment was performed in the lab on commercial plastic tubing materials that were submitted to IPA under harsh conditions. The results of the GC-MS analysis revealed the presence of many compounds that served has target for further tests. Secondly, tests were done on early and mid-season maple sap and syrup coming from many sugarbushes using IPA or not to determine potential concentrations of plastic residues. Results obtained from sap and syrup samples showed that no quantifiable (syrup and reinforced the need to thoroughly rinse the tubing system at the beginning of the season for both sanitized and non sanitized systems.

    Maple syrup is used as a premium natural sweeter, and is known for being good for human health. In the present study, we investigate whether maple syrup is suitable as a sweetener in the management of type 2 diabetes using Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a model of type 2 diabetes mellitus. OLETF rats develop type 2 diabetes mellitus by 30 weeks of age, and 60-week-old OLETF rats show hyperglycemia and hypoinsulinemia via pancreatic β-cell dysfunction. The administration of sucrose or maple syrup following an OGT test increased plasma glucose (PG) levels in OLETF rats, but the enhancement in PG following the oral administration of maple syrup was lower than in the case of sucrose administration in both 30- and 60-week-old OLETF rats. Although, the insulin levels in 30-week-old OLETF rats also increased following the oral administration of sucrose or maple syrup, no increase in insulin levels was seen in 60-week-old OLETF rats following the oral administration of either sucrose or maple syrup. No significant differences were observed in insulin levels between sucrose- and maple syrup-administered OLETF rats at either 30 or 60 weeks of age. The present study strongly suggests that the maple syrup may have a lower glycemic index than sucrose, which may help in the prevention of type 2 diabetes.

    In this study, the carbohydrate composition of high-fructose corn syrups (HFCS) from commercial manufacturers as well as from beekeepers was characterized by GC-MS. Sucrose syrups (SS) were also included in this work for comparison. Fructosyl-fructoses and some unknown carbohydrates, which could correspond to fructosyl-glucoses, have been detected in HFCS for the first time, whereas SS were mainly characterized by the high contents of sucrose. Hydroxymethylfurfural (HMF) content of samples supplied by beekeepers was much more variable; the mean level of HMF was 64.61 ppm (+/-16.92 ppm, 95% CI ranging from 26.91 to 102.31 ppm). Syrups were used to feed caged bees and the resulting honeys produced were analyzed in order to determine their influence in carbohydrate composition. Fructosyl-fructoses were mainly detected in honeys from bees fed with HFCS, but not from those honeys coming from free-flying bees or bees fed with SS.

    Berry juices are a rich source of phenolic compounds exhibiting antioxidant activity. Unfortu- nately, polyphenols and especially anthocyanins are degraded during storage. The levels of total phenolic compounds, phenolic acids, flavonoids, and antho- cyanins as well as antioxidant activity (radical scavenging ability against DPPH and ABTS+• and chelating power Fe2+) were determined in raspberry juices (obtained after enzymatic treatment with three commercial pectinolytic enzyme preparations) and syrups (obtained by the addition of sucrose at concentrations of 30% and 70%) during storage. During the five-month storage of juices and syrups at room temperature, there was significant re- duction in the level of phenolic compounds, in particular anthocyanins (up to 95% in relation to the initial content). Storage of raspberry juices and syrups also resulted in a reduction in antioxidant activity. The enzymatic treatment of the raspberry mash generally increased the losses of anthocyanins. The addition of sugar to fruit juices only slightly reduced these losses.

    This study aimed to investigate the effect of violet syrup on cough alleviation in children with intermittent asthma. In a parallel, double-blind, randomized controlled trial, 182 children aged 2 to 12 years with intermittent asthma were randomly assigned 1:1 to receive violet syrup or placebo along with the common standard treatments in both groups (short-acting β-agonist). Both groups were evaluated in terms of the duration until cough suppression was achieved. No significant difference was observed in basic characteristics. The duration lasting to yield more than 50% cough reduction and 100% cough suppression was significantly less in the violet syrup group compared to placebo (P = .001, P syrup. This study showed that the adjuvant use of violet syrup with short-acting β-agonist can enhance the cough suppression in children with intermittent asthma. © The Author(s) 2015.

    Background: Among different categories of sedative agents, benzodiazepines have been prescribed for more than three decades to patients of all ages. The effective and predictable sedative and amnestic effects of benzodiazepines support their use in pediatric patients. Midazolam is one of the most extensively used benzodiazepines in this age group. Oral form of drug is the best accepted route of administration in children. Objectives: The purpose of this study was to compare the efficacy and safety of a commercially midazolam syrup versus orally administered IV midazolam in uncooperative dental patients. Second objective was to determine whether differences concerning sedation success can be explained by child‘s behavioral problems and dental fear. Patients and Methods: Eighty eight uncooperative dental patients (Frankl Scales 1,2) aged 3 to 6 years, and ASA I participated in this double blind, parallel randomized, controlled clinical trial. Midazolam was administered in a dose of 0.5 mg/kg for children under the age 5 and 0.2 mg/kg in patients over 5 years of age. Physiologic parameters including heart rate, respiratory rate, oxygen saturation and blood pressure were recorded. Behavior assessment was conducted throughout the course of treatment using Houpt Sedation Rating Scale and at critical moments of treatment (injection and cavity preparation) by North Carolina Scale. Dental fear and behavioral problems were evaluated using Child Fear Schedule Survey-Dental Subscale (CFSS-DS), and Strength and Difficulties Questionnaire (SDQ). Independent t-test, Chi-Square, and Pearson correlation were used for statistical analysis. Results: Acceptable overall sedation ratings were observed in 90% and 86% of syrup and IV/Oral group respectively; Chi-Square P = 0.5. Other domains of Houpt Scale including: sleep, crying and movement were also not significantly different between groups. Physiological parameters remained in normal limits during study without significant

    Full Text Available The reported patent-pending system comprises a novel biohydrogen reactor with a gravity settler for decoupling of SRT from HRT. The biohydrogenator was operated for 100 days at 37 °C, hydraulic retention time 8 h and solids retention time ranging from 2.2–2.5 days. The feed was a corn-syrup waste generated as a byproduct from an industrial facility for bioethanol production located in southwestern Ontario, Canada. The system was initially started up with a synthetic feed containing glucose at concentration of 8 g/L and other essential inorganics. Anaerobicaly-digested sludge from the St. Mary’s wastewater treatment plant (St. Mary, Ontario, Canada was used as the seed, and was heat treated at 70 °C for 30 min to inhibit methanogens. After 10 days, when the hydrogen production was steady, the corn-syrup waste was introduced to the system. Glucose was the main constituent in the corn-syrup; its concentration was varied over a period of 90 days from 8 to 25 g/L. The change in glucose concentration was used to study the impact of variable organic loading on the stability of hydrogen production in the biohydrogenator. Hydrogen production rate increased from 10 L H2/L·d to 34 L H2/L·d with the increase of organic loading rate (OLR from 26 to 81 gCOD/L·d, while a maximum hydrogen yield of 430 mL H2/gCOD was achieved in the system with an overall average of 385 mL H2/gCOD.

    Due to an increase in the number of methadone maintenance clinics in the past decade in Iran, acute methadone overdose has become one of the common poisonings in our society. To compare the characteristics of methadone poisoning between syrup and tablet formulation as well as to discuss the relative advantages and disadvantages of poisoning from the perspective of toxicity. In a retrospective cross-sectional study from 2000 to 2010, sampled data of all hospitalized methadone-overdosed patients were collected through chart review of hospital records. Concurrently, the total number of methadone sales was gathered. A total of 1426 patients with methadone poisoning had been hospitalized, including 1072 cases who consumed syrup or tablet solely. Mean ± SD milligram ingested dose of syrup and tablet were 153 ± 339 and 88 ± 274, respectively (p syrup formulation, particularly by children under 12 years old after being mistaken for cough mixture or water. Conversely, exposure to methadone tablets was more common in patients with suicidal intent. There was no statistically significant difference between the rates of intubation and death between the two groups. Higher doses of methadone in the syrup form appear to exert a similar severity of poisoning and outcomes compared to lesser doses of that in the tablet form. Similarities in outcomes, despite differences in exposure history, may reflect relatively prompt transfer to hospital and adequate provision of clinical care, including supportive care and naloxone. In order to reduce the rate of poisoning, we recommend the use of child-resistant containers for dispensing syrup, reduction in methadone concentration, adding a coloring agent, special flavor, and education of patients on the safe storage of methadone in their home in order to reduce the occurrence of accidental poisonings.

    Full Text Available Background: The impact of honey or vinegar on several metabolic abnormalities has been studied separately, a mixture of these two ingredients known as honey vinegar syrup (HVS has not been investigated previously so far. The aim of this study was to assess the impact of HVS consumption (Iranian′s traditional syrup on glycemic parameters and lipid profiles in healthy individuals. Methods: We conducted a 4-week, randomized, controlled, parallel study consisting of two groups of nonobese healthy volunteers. All subjects were asked to stay on their normal diet. Intervention group (n = 36 received a cup of HVS daily in the evening snack for 4-week (250 cc syrup contains 21.66 g honey vinegar. Assessments of fasting blood sugar (FBS, insulin, homeostasis model assessment of insulin resistance (HOMA-IR, total cholesterol (TC, triglyceride (TG, high-density lipoprotein cholesterol (HDL-C and low-density lipoprotein cholesterol (LDL-C were conducted at the baseline and after 4-week of study. Results: We observed no significant effect of HVS on FBS, HOMA-IR, LDL-C and TG. A significant effect of HVS was found on increasing fasting insulin and HOMA-IR and reduction in TC level only in intervention group (Δ =3.39 P = 0.01, Δ =1.65 P = 0.03, Δ = −9.43 P = 0.005, respectively. Changes of FBS, TG and LDL-C were 1.83 mg/dl, −1.53 mg/dl and − 3.99 mg/dl respectively in the intervention group. These changes were not significant. An unfavorable and significant reduction in HDL-C level was also observed between two groups (Δ = −4.82 P < 0.001 in the intervention group. Conclusions: Honey vinegar syrup increased fasting insulin level and decreased TC level in the intervention group. HVS had an unfavorable effect on HDL-C level. Further prospective investigations are warranted to confirm these findings.

    Rice syrup solids, rice protein, and casein hydrolysate were added to experimental oral rehydration solutions in various combinations and tested in a rat intestinal perfusion system. Chronic osmotic diarrhea was induced in juvenile rats by supplying the cathartic agents, magnesium citrate and phenolphthalein, in their drinking water for 1 week. The experimental oral rehydration solutions were compared with standard oral rehydration solutions containing 20 gm/L or 30 gm/L of glucose and with each other to determine if there were significant differences in net water, sodium, or potassium absorption. An oral rehydration solution containing 30 gm/L of rice syrup solids had a net water absorption rate significantly higher than that of the standard 20 gm/L glucose-based oral rehydration solution (2.1 +/- 0.62 versus 1.5 +/- 0.48 microliters/[min x cm], p less than 0.05). Casein hydrolysate did not significantly affect net water absorption. However, combinations of 30 gm/L rice syrup solids and 5 gm/L casein hydrolysate significantly increased (p less than 0.05) net sodium and potassium absorption compared with the 20 gm/L glucose-based oral rehydration solution but not versus rice syrup solids alone. Oral rehydration solutions containing 30 gm/L rice syrup solids plus 5 gm/L rice protein, and 30 gm/L rice syrup solids plus 5 gm/L casein hydrolysate, had net water absorption rates significantly higher than the rate of a 30 gm/L glucose-based oral rehydration solution (2.5 +/- 0.36 and 2.4 +/- 0.38, respectively, versus 0.87 +/- 0.40 microliters/[min x cm], p less than 0.05). Rice protein and casein hydrolysate, however, did not significantly affect net water, sodium, or potassium absorption when added to rice protein glucose-based oral rehydration solutions. An inverse correlation between osmolality and net water absorption was observed (r = -0.653, p less than 0.02). The data suggest that substitution of rice syrup solids for glucose in oral rehydration solutions will

    The influence of glucose syrup on the retrogradation of cereal starches was investigated. Laboratory isolated starches from wheat (WS) and oats (OS - oat starch and ROS - residual oat starch) were used in this research. ROS was isolated from the flour left after the industrial separation of β-glucans. Gelatinization temperature of oat starches (63.82 °C and 64.01 °C for OS and ROS, respectively) was higher than for WS (62.26 °C), whereas gelatinization enthalpy for oat starches (8.87 J/g and 9.09 J/g for OS and ROS, respectively) was lower than for WS (9.99 J/g). Moreover, retrogradation percentage (%R) was similar for both oat starches (29.76% and 27.72% for OS and ROS, respectively), and was substantially lower than for WS (42.04%). The introduction of glucose syrup into system reduced the extent of the retrogradation. Rate of the process was suppressed for WS and ROS, whereas for OS it was increased. β-Glucan production process had no significant effect on the gelatinization and retrogradation of oat starch.

    This study employed statistically based experimental designs to optimize fermentation conditions for hydrogen production from sweet sorghum syrup by anaerobic mixed cultures. Initial screening of important factors influencing hydrogen production, i.e., total sugar, initial pH, nutrient solution, iron (II) sulphate (FeSO{sub 4}), peptone and sodium bicarbonate was conducted by the Plackett-Burman method. Results indicated that only FeSO{sub 4} had statistically significant (P {<=} 0.005) influences on specific hydrogen production (P{sub s}) while total sugar and initial pH had an interdependent effect on P{sub s}. Optimal conditions for the maximal P{sub s} were 25 g/L total sugar, 4.75 initial pH and 1.45 g/L FeSO{sub 4} in which P{sub s} of 6897 mL H{sub 2}/L was estimated. Estimated optimum conditions revealed only 0.04% difference from the actual P{sub s} of 6864 mL H{sub 2}/L which suggested that the optimal conditions obtained can be practically applied to produce hydrogen from sweet sorghum syrup with the least error.

    The purpose of the present study was to evaluate the taste and smell of Tulobuterol Dry Syrup (TB-DS) in its original form (formulation A) and generic form (formulations B and C) by means of gustatory sensation tests and taste and smell sensors. In addition, the physicochemical properties of the syrups in a solid state were compared. Evaluation of sweetness with a powdered sample revealed significant differences between formulation A and formulation B and between formulation B and formulation C. In contrast, the results of principal component analysis (PCA) with a taste sensor revealed differences in principal component 1 (PC 1) among formulations A, B, and C. Smell sensor measurement of powdered samples revealed differences in products in terms of only PC 1, but these results were not related to the results of gustatory sensation testing with a smell sensor. Measurement of particle size distribution and scanning electron microscopy revealed differences in the particle diameter and particle surface shape for each product. Formulation B had the strongest absorption in the near-infrared spectrum, followed by formulation A and then formulation C. Accordingly, differences in preparations were presumably caused by variations in manufacturing specifications, such as types of additives and their content and coating methods used. In other words, the characteristics of each product were revealed by evaluation of their physical properties, sensing of taste and smell, and human gustatory sensation tests.

    Herbal and Ayurvedic preparations, widely used in Pakistan and the developing world, present serious risk of heavy metal toxicity related to their medicinal content and prolonged use by patients. The objective of this study was to find out the concentration of heavy metals in Herbal and Ayurvedic liquid preparations commonly used for treatment of different diseases, from local markets of Hazara. Methods: The cross sectional survey of traditional herbal and Ayurvedic medicine shops included ten liquid preparations selected from local shops of Mansehra and Abbottabad after interviewing the shopkeepers; so as to select the most commonly sold preparations along with their indications. All samples were analysed on standard Atomic Absorption Spectroscopy for qualitative and quantitative study of toxic heavy metals (Mercury, Iron, Zinc, Lead, Manganese and Arsenic). Results: Toxic levels of Mercury were present in seven syrups, i.e., (Kashneeze, Akseer e Pachas, Tankar, Sharbat e folad, Urosinal, Akseer e Jigar and Amrat dhara) while Arsenic was present only in Urosinal. Iron, Zinc, Manganese and Lead were present in permissible limits in all syrups. Conclusion: Mercury and Arsenic are present in local Herbal and Ayurvedic liquid preparations far beyond the permissible limits as proposed by the International Regulatory Authorities for health drugs while the rest of metals, i.e., Zinc, Manganese, and Iron are within the therapeutic limits.

    We investigated the effects of temperature, water activity (a(w)), and syrup film composition on the CFU growth of Wallemia sebi in crystalline sugar. At a high a(w) (0.82) at both high (20 degrees C) and low (10 degrees C) temperatures, the CFU growth of W. sebi in both white and extrawhite sugar could be described using a modified Gompertz model. At a low a(w) (0.76), however, the modified Gompertz model could not be fitted to the CFU data obtained with the two sugars due to long CFU growth lags and low maximum specific CFU growth rates of W. sebi at 20 degrees C and due to the fact that growth did not occur at 10 degrees C. At an a(w) of 0.82, regardless of the temperature, the carrying capacity (i.e., the cell concentration at t = infinity) of extrawhite sugar was lower than that of white sugar. Together with the fact that the syrup film of extrawhite sugar contained less amino-nitrogen relative to other macronutrients than the syrup film of white sugar, these results suggest that CFU growth of W. sebi in extrawhite sugar may be nitrogen limited. We developed a secondary growth model which is able to predict colony growth lags of W. sebi on syrup agar as a function of temperature and a(w). The ability of this model to predict CFU growth lags of W. sebi in crystalline sugar was assessed.

    The safety of rare sugar syrup obtained from high-fructose corn syrup under slightly alkaline conditions was studied. Mutagenicity of rare sugar syrup was assessed by a reverse mutation assay using Salmonella typhimurium and Escherichia coli, and an in vitro chromosomal aberration assay using Chinese hamster lung cell line (CHL/IU). No mutagenicity of rare sugar syrup was detected under these experimental conditions. Oral administration of single dose (15,000 mg/kg) of rare sugar syrup to rats caused no abnormalities, suggesting no adverse effect of rare sugar syrup. In humans, the acute non-effect level of rare sugar syrup for causing diarrhea was estimated as 0.9 g/kg body weight as dry solid base in both males and females.

    A complete characterization of yacon syrup was performed by analytical techniques, including NMR and UPLC-QTOF-MS E . The effect of the different stages of yacon syrup production on fructooligosaccharides (FOS) and chlorogenic acid (CGA) contents were also evaluated. As a result, in addition to higher levels of FOS and CGA, some mineral elements, such as K, Ca and P, and essential amino acids, such as tryptophan, valine, and threonine, were determined in yacon syrup. Twenty-five compounds were putatively identified, and the main compounds were phenolics derived from quinic and trans-cinnamic acids. Considering the different stages of yacon syrup production, the results indicate that the contents of FOS and CGA were maintained in the pulping, enzymatic maceration and microfiltration, leading to a concentration of these components in the last stage of processing (vacuum concentration). These results will be used to fortify this innovative and promising product in the area of functional foods. Copyright © 2017. Published by Elsevier Ltd.

    Mostafa, Yasser S.; Alamri, Saad A.

    2012-01-01

    Date syrup as an economical source of carbohydrates and immobilized Aspergillus niger J4, which was entrapped in calcium alginate pellets, were employed for enhancing the production of citric acid. Maximum production was achieved by pre-treating date syrup with 1.5% tricalcium phosphate to remove heavy metals. The production of citric acid using a pretreated medium was 38.87% higher than an untreated one that consumed sugar. The appropriate presence of nitrogen, phosphate and magnesium appeared to be important in order for citric acid to accumulate. The production of citric acid and the consumed sugar was higher when using 0.1% ammonium nitrate as the best source of nitrogen. The production of citric acid increased significantly when 0.1 g/l of KH2PO4 was added to the medium of date syrup. The addition of magnesium sulfate at the rate of 0.20 g/l had a stimulating effect on the production of citric acid. Maximum production of citric acid was obtained when calcium chloride was absent. One of the most important benefits of immobilized cells is their ability and stability to produce citric acid under a repeated batch culture. Over four repeated batches, the production of citric acid production was maintained for 24 days when each cycle continued for 144 h. The results obtained in the repeated batch cultivation using date syrup confirmed that date syrup could be used as a medium for the industrial production of citric acid. PMID:23961184

    Full Text Available A plastic tubing system operated under vacuum is usually used to collect sap from maple trees during spring time to produce maple syrup. This system is commonly sanitized with isopropyl alcohol (IPA to remove microbial contamination colonizing the system during the sugar season. Questions have been raised whether IPA would contribute to the leaching of plastic residues in maple sap and syrup coming from sanitized systems. First, an extraction experiment was performed in the lab on commercial plastic tubing materials that were submitted to IPA under harsh conditions. The results of the GC-MS analysis revealed the presence of many compounds that served has target for further tests. Secondly, tests were done on early and mid-season maple sap and syrup coming from many sugarbushes using IPA or not to determine potential concentrations of plastic residues. Results obtained from sap and syrup samples showed that no quantifiable (< 1–75 μg/L concentration of any plastic molecules tested was determined in all samples coming from IPA treated or not treated systems. However, some samples of first sap run used as a rinse solution to be discarded before the season start and that were coming from non sanitized or IPA sanitized systems, showed quantifiable concentrations of chemical residue such as ultraviolet protector (octabenzone. These results show that IPA can be safely used to sanitize maple sap collection system in regards to the leaching of plastic residues in maple sap and syrup and reinforced the need to thoroughly rinse the tubing system at the beginning of the season for both sanitized and non sanitized systems.

    Myrtle (Myrtus communis L.) has been used in the Iranian Traditional Medicine as a treatment for abnormal uterine bleeding-menometrorrhagia. The main aim of this study is to evaluate the effect of myrtle fruit syrup on abnormal uterine bleeding-menometrorrhagia. A randomized, double-blind, placebo-controlled pilot study was conducted on 30 women suffering from abnormal uterine bleeding-menometrorrhagia. Treatment comprised of giving 15 ml oral myrtle syrup daily (5 ml three times a day) for 7 days starting from the onset of bleeding. The myrtle syrup along with placebo was repeated for 3 consecutive menstrual periods. Menstrual duration and number of used pads were recorded by the Pictorial Blood loss Assessment Chart at the end of each menstrual period. The quality of life was also evaluated using the menorrhagia questionnaire. The mean number of bleeding days significantly declined from 10.6 ± 2.7 days to 8.2 ± 1.9 days after 3 months treatment with the syrup (p = 0.01) and consequently the participants in the intervention group used fewer pads after 3 months (16.4 ± 10.7) compared with the number of pads used at the beginning of the treatment (22.7 ± 12.0, p = 0.01). Bleeding days and number of pads used by the participants in the placebo group did not change significantly. Also significant changes of quality of life scores were observed in the intervention group after 3 months compared to the baseline. Myrtle syrup is introduced as a potential remedy for abnormal uterine bleeding-menometrorrhagia.

    To examine the pathological findings that occurred in the lens and cornea and biochemical findings in the lens of rats fed with corn syrup and the protective effects of alpha lipoic acid (ALA). Twenty-four rats were randomly divided into three groups. Group I served as the control group. Group II was used as the study group; the rats were treated with 30% corn sugar solution for 10 weeks. Group III was the treatment group. Corn syrup was given by the oral route to the rats during the study, and ALA (100 mg/kg) was added to the treatment 4 weeks after the study began. At the end of the experiment, central corneal thickness (CCT) was measured in all rats with an ultrasonic pachymeter. Then the right eyes of the rats were enucleated for histopathological examination of the cornea and lens. The left lenses were homogenized for biochemical analyses. The lenses of the rats treated with corn syrup revealed severe damage; many lens fibers appeared swollen and ruptured with large vacuoles near the lens epithelium. In addition, malondialdehyde (MDA) levels, a parameter of oxidative stress, increased but not significantly in Group II; however. ALA treatment decreased MDA levels significantly. Antioxidant enzyme and catalase (CAT) activities were significantly decreased in Group II, and ALA treatment increased these activities; however, the increase was not significant. Changes were observed in the cornea such as epithelial alterations, subepithelial vacuolizations, collagen fibers loss in the stromal layer, interruptions in the subepithelial basement membrane and central corneal thickening. Corn syrup can cause severe damage in rat lenses and corneas. However, ALA ameliorates the effect of corn syrup-related lesions on the cornea and lens.

    Date syrup is rich in fermentable sugars and may be used as a substrate for different microbial fermentations, including lactic acid fermentation processes. The beneficial effects of ultrasounds (US) on bioprocesses have been reported for several microorganisms, due to the enhancement of cell growth, as well as improvements in yields and productivities. Therefore, US treatments (30 kHz, 100 W, 10-30 min) were applied to two lactobacilli (Lactobacillus helveticus PTCC 1332 and Lactobacillus acidophilus PTCC 1643), during fermentation using date syrup as substrate. The effects on lactic acid fermentation were evaluated by analyzing cell growth (dry cell weight and viable cell count), substrate consumption (quantification of glucose and fructose), and product formation (quantification of lactic acid) over time. The effects of US were also evaluated on cell membrane permeability. Both lactobacilli were able to grow well on date syrup without the need for addition of further ingredients. The US effects were highly dependent on treatment duration: treatments of 10- and 20-min stimulated lactobacilli growth, while the treatment extension to 30 min negatively affected cell growth. Similarly, the 10- and 20-min treatments increased sugar consumption and lactic acid production, contrarily to the 30-min treatment. All US treatments increased cell membrane permeability, with a more pronounced effect at more extended treatments. The results of this work showed that application of appropriate US treatments could be a useful tool for stimulation of lactic acid production from date syrup, as well as for other fermentative processes that use date syrup as substrate.

    Date syrup as an economical source of carbohydrates and immobilized Aspergillus niger J4, which was entrapped in calcium alginate pellets, were employed for enhancing the production of citric acid. Maximum production was achieved by pre-treating date syrup with 1.5% tricalcium phosphate to remove heavy metals. The production of citric acid using a pretreated medium was 38.87% higher than an untreated one that consumed sugar. The appropriate presence of nitrogen, phosphate and magnesium appeared to be important in order for citric acid to accumulate. The production of citric acid and the consumed sugar was higher when using 0.1% ammonium nitrate as the best source of nitrogen. The production of citric acid increased significantly when 0.1 g/l of KH2PO4 was added to the medium of date syrup. The addition of magnesium sulfate at the rate of 0.20 g/l had a stimulating effect on the production of citric acid. Maximum production of citric acid was obtained when calcium chloride was absent. One of the most important benefits of immobilized cells is their ability and stability to produce citric acid under a repeated batch culture. Over four repeated batches, the production of citric acid production was maintained for 24 days when each cycle continued for 144 h. The results obtained in the repeated batch cultivation using date syrup confirmed that date syrup could be used as a medium for the industrial production of citric acid.

    Maple syrup urine disease (MSUD) is a hereditary disorder of branched chain amino/keto acid metabolism, caused by a decreased activity of the branched-chain alpha- ketoacid dehydrogenase complex (BCKAD), which leads to abnormal elevated plasma concentrations of branched-chain amino acids (BCAAs) clinically manifested as a heavy burden for Central Nervous system. The toxic accumulation of substrates promotes the development of a severe and rapidly progressive neonatal encephalopathy if treatment is not immediately given. This disorder has a specific medical management in acute phase in order to minimize mortality and morbidity. For all those reasons, it is important to include the MSUD as a possible diagnosis in a encephalopathic newborn. We present a colombian newborn with classical MSUD with fatal outcome as an example of metabolic emergency and a differential diagnosis in the encephalopathic newborn.

    We describe the management and outcomes of pregnancy in two women affected with Maple syrup urine disease (MSUD). Both patients had classical disease diagnosed in the newborn period and were managed with low-protein diets and supplements, although compliance was moderately poor throughout life. Both pregnancies were complicated by poor compliance and one patient had a metabolic decompensation, which included seizures and profound encephalopathy, at the end of the first trimester. Peri-partum management required a coordinated team approach including a high-calorie and low-protein diet. Both patients had elevated leucine levels in the post-partum period - one due to mastitis and the other due to poor dietary and supplement compliance combined with uterine involution. On later review, leucine had returned to pre-pregnancy levels. Both infants were unaffected and have made normal developmental progress in the subsequent 1 to 2 years.

    Full Text Available Maple syrup urine disease is caused by a deficiency in the branched chain ketoacid dehydrogenase (BCKAD complex. This results in the accumulation of branched chain amino acids (BCAA and branched chain ketoacids in the body. Even when aggressively treated with dietary restriction of BCAA, patients experience long term cognitive, neurological and psychosocial problems. Liver transplantation from deceased donors has been shown to be an effective modality in introducing adequate BCKAD activity, attaining a metabolic cure for patients. Here, we report the clinical course of the first known patient with classic MSUD who received two consecutive partial liver grafts from two different living non-carrier donors and his five year outcome posttransplant. We also show that despite the failure of the first liver graft, and initial acute cellular rejection of the second liver graft in our patient, his metabolic control remained good without metabolic decompensation.

    A mixture of codeine cough syrup with alcohol and/or a soft drink known as "purple drank" has gained media attention in recent years as a drug associated with professional athletes and southern rap music. The existing research on purple drank consumption has primarily utilized samples of African Americans residing in the Houston, Texas area. This is the first scholarly study of purple drank use outside of the Houston, Texas area among a general population of young adults, and indicates that purple drank use is not limited to African American males. The findings depict higher odds of the use of purple drank among other racial and ethnic groups, males, and homosexual, bisexual, and transgender college students from urban areas.

    Full Text Available In 2002, the American Academy Of Pediatric Dentistry had developed the Caries-risk Assessment Tool (CAT based on a set of physical, environmental and general health factors. One of the components of CAT is children with chronic medical conditions requiring long term medication being at a risk of dental caries as a side-effect. Children on long term medication due to medical conditions consume syrups in bulk. The child′s oral health is often neglected due to the preoccupation of the parent with the child′s medical problem. Sometimes physicians are unaware of the high sugar content of medications. This review explores the detrimental effects of paediatric medications on oral health administered to chronically ill children and the risk to which children are exposed unknowingly.

  9. Diet-dependent gene expression in honey bees: honey vs. sucrose or high fructose corn syrup.

    2014-07-17

    Severe declines in honey bee populations have made it imperative to understand key factors impacting honey bee health. Of major concern is nutrition, as malnutrition in honey bees is associated with immune system impairment and increased pesticide susceptibility. Beekeepers often feed high fructose corn syrup (HFCS) or sucrose after harvesting honey or during periods of nectar dearth. We report that, relative to honey, chronic feeding of either of these two alternative carbohydrate sources elicited hundreds of differences in gene expression in the fat body, a peripheral nutrient-sensing tissue analogous to vertebrate liver and adipose tissues. These expression differences included genes involved in protein metabolism and oxidation-reduction, including some involved in tyrosine and phenylalanine metabolism. Differences between HFCS and sucrose diets were much more subtle and included a few genes involved in carbohydrate and lipid metabolism. Our results suggest that bees receive nutritional components from honey that are not provided by alternative food sources widely used in apiculture.

    Full Text Available The fructose-glucose syrup is currently used instead of sucrose in bakery products for economic and technological reasons. The authors investigated the extent to which this change affects the formation of non-enzymatic browning products (Advanced Glycation End - AGE-Products and melanoidins. Formation of these products in model systems - mixtures of various sugars (sucrose, fructose, glucose - concentration 6% with glycine (concentration 0.7% or/and lysine (concentration 0.3%, heat-treated 60 - 100 °C for 15, 30, 45 and 60 min, was studied. The formation of AGE products and melanoidins was determined on the basis of absorption at 294 nm (AGE-products and 420 nm (melanoidins, respectively. The results pointed out notable difference in the AGE-products and also melanoidins formation for a variety of sugars. The reactivity of sucrose was low even at 100 °C/60 min. Fructose and glucose originated a significantly increasing of the non-enzymatic browning products formation. The reactivity of fructose was in the caramelisation and also in Maillard reactions the highest in any combination of composition. Lysine is the most reactive amino acid which takes part in Maillard reactions even if it is bound to protein. The non-enzymatic browning reactions result in the formation of non-digestible cross-linked proteins. Lysine is also the limiting essential amino acid of most cereals. Due to the lysine properties, reduction in protein quality is the most important nutritional effect of Maillard reactions in food. The sucrose replacement by fructose-glucose syrup in bakery products leads to more extensive non-enzymatic browning reactions, i.e. caramelisation and also Maillard reactions, while changes are in the Maillard reaction more pronounced.

    When planning and preparing for climate change, practitioners rely on climate models to help them make informed decisions. All climate change model data ultimately derive from global-scale models, which are typically too coarse for local-scale decision making; thus, these models are often "downscaled" in order to resolve finer details within the decision space. A few downscaling approaches exist, each with a unique set of strengths and limitations, yet their implications on any particular decision are not always clear to decision makers. Using maple syrup production as a case study, we demonstrate a possible method of evaluating the sensitivity of a specific decision to downscaling method selection. We compare two downscaling techniques (dynamical and statistical) and two training methods within the statistical downscaling approach (bias-corrected spatial disaggregation, or BCSD, and bias corrected constructed analogs, or BCCA) with respect to their ability to capture daily freeze- thaw cycles, the driver of sapflow in maple syrup production. For each downscaling approach, we evaluate simulations of historical freeze-thaw patterns using gridded temperature observations, and compare projected changes in freeze-thaw patterns by mid-century. We discuss the implications of our results on the decision of "when to tap" faced by maple syrup producers, as well as similar decisions in other industries. Our results reveal which downscaling technique(s) is (are) best suited for helping maple syrup producers make plans toward adapting their tapping practices for climate change. In addition, our results provide producers with a plausible range of optimal tapping dates by mid-century, based on the most skilled downscaling approach. Finally, we highlight insights relevant to the climate modeling community, and lessons learned toward making climate science actionable.

    Neonatal maple syrup urine disease (MSUD) is associated with diffuse oedema and characteristic MSUD oedema. We present a newborn infant with two coexisting different types of oedema. The myelinated white matter showed a marked decrease in the water apparent diffusion coefficient (ADC) compatible with cytotoxic oedema. The unmyelinated white matter showed an increase in ADC, consistent with vasogenic-interstitial oedema. On follow-up studies, the cytotoxic oedema showed improvement, but the vasogenic-interstitial oedema progressed into brain atrophy. (orig.)

    Honey bee colony feeding trials were conducted to determine whether differential effects of carbohydrate feeding (sucrose syrup (SS) vs. high fructose corn syrup, or HFCS) could be measured between colonies fed exclusively on these syrups. In one experiment, there was a significant difference in mean wax production between the treatment groups and a significant interaction between time and treatment for the colonies confined in a flight arena. On average, the colonies supplied with SS built 7916.7 cm2 ± 1015.25 cm2 honeycomb, while the colonies supplied with HFCS built 4571.63 cm2 ± 786.45 cm2. The mean mass of bees supplied with HFCS was 4.65 kg (± 0.97 kg), while those supplied with sucrose had a mean of 8.27 kg (± 1.26). There was no significant difference between treatment groups in terms of brood rearing. Differences in brood production were complicated due to possible nutritional deficiencies experienced by both treatment groups. In the second experiment, colonies supplemented with SS through the winter months at a remote field site exhibited increased spring brood production when compared to colonies fed with HFCS. The differences in adult bee populations were significant, having an overall average of 10.0 ± 1.3 frames of bees fed the sucrose syrup between November 2008 and April 2009, compared to 7.5 ± 1.6 frames of bees fed exclusively on HFCS. For commercial queen beekeepers, feeding the right supplementary carbohydrates could be especially important, given the findings of this study. PMID:23886010

    A liquid chromatography/tandem mass spectrometry (LC-MS/MS) method is developed to simultaneously determine 20 synthetic dyes (New Coccine, Indigo Carmine, Erythrosine, Tartrazine, Sunset Yellow FCF, Fast Green FCF, Brilliant Blue FCF, Allura Red AC, Amaranth, Dimethyl Yellow, Fast Garnet GBC, Para Red, Sudan I, Sudan II, Sudan III, Sudan IV, Sudan Orange G, Sudan Red 7B, Sudan Red B, and Sudan Red G) in food samples. This method offers high sensitivity and selectivity through the selection of two fragment ion transitions under multiple reaction monitoring mode to satisfy the requirements of both quantitation and qualitation. Using LC-MS/MS, the newly developed extraction protocol used in this study is rapid and simple and does not require the use of solid-phase extraction cartridges. The linearities and recoveries of the method are observed at the concentration range of 0.10-200 μg/kg and more than 90% for all dyes, respectively. The method has been successfully applied to screen 18 commercial chili powders and six commercial syrup-preserved fruits purchased from retail establishments in Taipei City. The results show that three legal food dyes, Tartrazine, and/or Sunset Yellow FCF, and/or New Coccine, are present in some syrup-preserved fruits. Amaranth, an illegal food dye in certain countries but declared illegal in Taiwan, is found in an imported syrup-preserved fruit. Copyright © 2014. Published by Elsevier B.V.

    The aim of this study was to evaluate the potential of natural humectants such as honey and rice syrup to replace sorbitol in the production of restructured duck jerky. Each humectant was mixed at 3%, 6%, and 10% (wt/wt) concentrations with the marinating solution. The values of water activity and the moisture-to-protein ratio of all of the samples were maintained below 0.75. Jerky samples treated with honey retained more moisture than those exposed to other treatments. Among all samples, those treated with 10% sorbitol produced the highest processing yield and the lowest shear force values. The highest L* value and the lowest b* value were observed for the sorbitol-treated sample, followed by the rice syrup- and honey-treated samples. Duck jerky samples treated with 10% honey showed the highest scores for the sensory parameters evaluated. The overall acceptability scores of samples treated with rice syrup were comparable with those of samples treated with sorbitol. Microscopic observation of restructured duck jerky samples treated with honey showed stable forms and smaller pores when compared with other treatments.

    Plants have been used since antiquity to treat and prevent diseases. Plantain (Plantago lanceolata L.) is traditionally used for the treatment of the common cold and associated symptoms such as cough. This study was designed to evaluate the oral toxicity of plantain leaf extract-containing syrup. In preparation of the toxicological examination and to ensure the quality of the herbal preparation, analytical methods were developed and validated, and stability testing was performed. Physicochemical and microbial quality, thin layer chromatography patterns and high performance liquid chromatography fingerprints complied with the specifications during the entire period of stability testing. The marker substance, acteoside, remained within the stability-defining limits of 90%–110% for quantitative determinations. No hint of toxicity emerged from 14-day repeat dose toxicity testing in rats. The animals were given doses of 3, 6, or 12 mL of syrup per kg body weight by gavage twice daily. All animals showed normal appearance and behavior. Body and organ weights at the end of the study were similar to those in the control group. Overall, P. lanceolata syrup was found to be stable and non-toxic under the test conditions. PMID:28327509

    The oral sugar test (OST) is used to identify equine insulin dysregulation (ID); however only a dose of 0.15 mL/kg bwt corn syrup has been evaluated. To determine the effect of varying the dose of corn syrup on insulin and glucose response to the OST and the test's ability to distinguish between ponies with a history of laminitis (PL) and without laminitis (NL). Randomised crossover experiment. After an overnight fast, in a three-way randomised crossover study with a 7-day washout, 0.15, 0.3 or 0.45 mL/kg bwt corn syrup was administered orally to eight ponies (5 PL and 3 NL) and blood obtained between 0 and 120 min. Serum [insulin] and [glucose] were measured using previously validated radioimmunoassay and colorimetric assays respectively. The repeatability of and the effect of continued pasture access on the dose that best distinguished PL and NL ponies were then assessed. The effect of dose, laminitis history and fasting on serum [insulin] and [glucose] responses were assessed using mixed-effects models. The serum [insulin] following 0.15 mL/kg bwt were not significantly different from 0.3 mL/kg bwt at any time point, while serum [insulin] following 0.45 mL/kg bwt significantly (Psyrup may be preferable to differentiate PL and NL ponies. © 2018 EVJ Ltd.

    Fifteen maple syrups were analyzed for 137 Cs and K (via 40 K) by using a low-background γ-ray counting system, and for B and K by using neutron capture prompt γ-ray activation analysis (PGAA). For low-background γ-ray counting, 3 ο limits of detection (24-hour counts) were 0.03 Bq 137 Cs/kg and 10 mg K/kg for 3.5-L portions and 0.08 Bq 137 Cs/kg and 20 mg K/kg for 1.0-L portions. K concentrations determined by the two methods (using 2-g portions for PGAA) were in excellent agreement. The products were obtained in 1991, with one produced in Maryland, three in New York, four in Pennsylvania, two in New Hampshire, and five in Canada. The average activity concentration for Canadian syrups (2.8 Bq 137 Cs/kg) was nearly a factor 20 greater than the average (0.15 Bq 137 Cs/kg) for the other syrups, but all 137 Cs activity concentrations were at least 100 times lower than those for which controls would be recommended according to Federal Radiation Council guidance. The data exhibited distinct groupings related to the sources of the products when the ratios 137 Cs activity to K content (Bq Cs /mg K ) were plotted vs. B concentrations.

    D-Allulose-containing rare sugar sweeteners have been categorized into two types, rare sugar syrup (RSS), consisting of 4 rare monosaccharides, and modified glucose syrup (MGS), rich in D-allulose, which was previously referred to D-psicose. The anti-obesity effect of RSS and D-allulose has been already clarified, but that of rare monosaccharides other than D-allulose in RSS has not yet been well understood. Here, we investigated and compared the anti-obesity effect of RSS and MGS in rats. Male Wistar rats were divided into 4 dietary groups: a high-sucrose control diet group (S), a high-fructose corn syrup diet group (HFCS), an RSS diet group (RSS), and an MGS diet group (MGS). RSS significantly suppressed abdominal adipose tissue weight and total body fat accumulation in comparison to sucrose. On the other hand, MGS reduced body weight gain, but not abdominal fat accumulation, relative to sucrose. The weight of the liver and kidneys was significantly higher in the RSS and MGS groups than in the S and HFCS groups, but serum biochemical parameters and hepatic lipids contents were not significantly different among the groups. The present study shows that two types of D-allulose-containing rare sugar sweeteners can suppress body fat accumulation or weight gain in a different manner and that RSS could be used as more effective sweeteners in place of sucrose and HFCS to maintain healthy body weight.

    Full Text Available A liquid chromatography/tandem mass spectrometry (LC-MS/MS method is developed to simultaneously determine 20 synthetic dyes (New Coccine, Indigo Carmine, Erythrosine, Tartrazine, Sunset Yellow FCF, Fast Green FCF, Brilliant Blue FCF, Allura Red AC, Amaranth, Dimethyl Yellow, Fast Garnet GBC, Para Red, Sudan I, Sudan II, Sudan III, Sudan IV, Sudan Orange G, Sudan Red 7B, Sudan Red B, and Sudan Red G in food samples. This method offers high sensitivity and selectivity through the selection of two fragment ion transitions under multiple reaction monitoring mode to satisfy the requirements of both quantitation and qualitation. Using LC-MS/MS, the newly developed extraction protocol used in this study is rapid and simple and does not require the use of solid-phase extraction cartridges. The linearities and recoveries of the method are observed at the concentration range of 0.10–200 μg/kg and more than 90% for all dyes, respectively. The method has been successfully applied to screen 18 commercial chili powders and six commercial syrup-preserved fruits purchased from retail establishments in Taipei City. The results show that three legal food dyes, Tartrazine, and/or Sunset Yellow FCF, and/or New Coccine, are present in some syrup-preserved fruits. Amaranth, an illegal food dye in certain countries but declared illegal in Taiwan, is found in an imported syrup-preserved fruit.

    Distribution of volcanic gasses in a conduit determines eruption style. Outgassing changes the distribution of volcanic gasses in a conduit.We here simulated the outgassing from ascending magma by slow decompression experiments. As molten magma ascends in a conduit, surrounding pressure becomes low and bubbles in magma expand. In our previous work, we found that the bubble expansion causes film rupturing and makes paths for outgassing. The crystals in magma may affect this newly found outgassing style. Accordingly, we slowly decompressed syrup foam including solid particles as a magma analogue. Experiments are conducted in an acrylic tank. We observed the expansion of three-phase magma analog from the front of the tank using a digital video camera. From the images and pressure measurements, we calculated time evolution of the syrup volume and permeability. We consider that there is no bubble segregation by the ascent of individual bubbles from the Stoke's velocity. We conducted our experiments with a viscosity range of 10-20 Pa s which is the same orders of magnitude of that of basaltic magma, 10-103 Pa s. At the beginning of the decompression, the volume change of the syrup foam is well explained by isothermal expansion. When the gas fractions reached to the 85-90%, we observed that deformations of bubble films caused film rupturing so that bubbles coalesce vertically to clear a path. As time elapsed, the measured gas volume in the foam becomes smaller than that estimated by the isothermal expansion, indicating the occurrence of outgassing. In the experiments with high volume fraction of solid particles (>30 vol.% for bubble-free liquid), we observed another new style of outgassing. Several large voids (> 10 mm in radius) appear at a middle height of the foam and connect each other to make a horizontally elongated cavity. The roof of the cavity collapses, and then massive outgassing occurs. At the beginning of the decompression until the foam collapses, outgassing

    To test for bioequivalence of 200 mg lacosamide oral tablet and syrup formulations. Additional objectives were to compare the pharmacokinetic profile of lacosamide in saliva and plasma, and to evaluate its tolerability. This open-label, randomized, two-way crossover trial was conducted in 16 healthy Caucasian male participants in Germany. The bioequivalence of 200 mg lacosamide tablet and syrup was evaluated using plasma to determine maximum measured concentration (C(max)) and area under the curve from zero to the last time point (AUC)(0-tz). Plasma and saliva samples for evaluation of pharmacokinetic parameters of lacosamide and the major metabolite O-desmethyl lacosamide (SPM 12809) were taken over 15 time points (0.5-72 h) and used to statistically compare bioavailability of the two. Urine samples were collected predose and over five time points (0-48 h) to evaluate the cumulative amount of unchanged drug and metabolite. Lacosamide median time to reach C(max) (t(max)) was 1 h for tablet and 0.5 h for syrup in plasma and saliva. Mean terminal half life (t(½)) for tablet and syrup was 12.5 and 12.4 h in plasma, and 13.1 and 13.3 h in saliva, respectively. Tablet and syrup mean plasma AUC(0-tz) was 84.5 and 83.3 μg/mL*h, respectively. Mean AUC(0-tz) in saliva was 93.2 μg/mL*h for tablet and syrup. Mean C(max) for tablet was 5.26 μg/mL in plasma and 5.63 μg/mL in saliva. Syrup mean C(max) was 5.14 and 8.32 μg/mL in plasma and saliva, respectively. Within 2 h of syrup administration, elevated lacosamide concentration in saliva compared to plasma was observed. The ratio of lacosamide syrup to tablet was 0.98 for C(max) and 0.99 for AUC(0-tz) in plasma, and 1.00 for AUC((0-tz)) in saliva; the 90% confidence intervals (CIs) for these parameters were within the range of 0.80-1.25, which meets accepted bioequivalence criteria. The syrup-to-tablet ratio for C(max) in saliva was 1.48, and the 90% CIs exceeded the accepted upper boundary for bioequivalence (1

    Iron in the form of oral supplements is routinely prescribed to children to help fight anemia, however tooth staining is a commonly reported complication. This study tests in vitro, the staining potential of two different forms of iron syrup on primary teeth. Forty caries free primary central incisors were divided into four groups of ten teeth each. The control group comprised of ten teeth immersed in artificial saliva, while the test solutions were comprised of different forms of iron mixed with vitamins such that the iron content of each solution was approximately 100 mg (from 100 to 101.1 mg). The test solutions used iron syrup (Ferrose®, SPIMACO, Jeddah, Saudi Arabia) with iron in the form of ferric oxide polymaltose (FOP), slow release formula (Ferroglobin®, Vitabiotics ltd., London, UK) containing ferrous fumarate (FF and a combination of the two (FOP + FF). All the teeth were then immersed for 72 h and subjected to a protocol developed by Lee et al. to test staining. Color changes were measured using a wave dispersion spectro-photometer (Color-Eye 7000A, X-Rite Gmbh, Regensdorf, Switzerland) on the exposed labial surface at 4, 8, 24, 48 and 72 h. Two-way ANOVA with Scheffe's post hoc test was used to determine significance of difference in shade, while the Kurskull-Wallis test used to determine the significance of difference in clinical staining (∆E > 3). While all three iron groups showed some amount of staining, the combination of the two forms of iron (FOP+FF) showed significantly lower incidence of clinical staining than the other two groups at the end of 72 h. At the end of 72 h the (FOP) had significantly higher ∆E than ferrous fumarate (FF ) while the combination (FOP+ FF) had a significantly lower ∆E than either group. In an in vitro model, combining different forms of iron seems to elicit a lower intensity of staining than equivalent doses of a single form of iron.

    This paper presents a procedure by which a simple and economical analytical column containing immobilized invertase was developed. This column has high efficiency of converting sucrose into inverted syrup rapidly. Gelatine beads were used for the immobilization of invertase. The enzyme was entrapped efficiently and was found to be stable and retained its activity over a period of 3 months. Immobilization parameters for maximum enzyme activity were estimated as temperature optima at 60 °C, pH optima 7.0 and 30 mg/mL enzyme concentration was found to give maximum immobilization (72 %). The reusability of the gelatine immobilized invertase was found to be seven times with a time interval of 24 h. The immobilized invertase presented a KM of 51.28 mM and Vmax of 0.334 mM/min. The time required to hydrolyse 50 % sucrose solution by a column of length 10 cm and diameter of 1.5 cm was found to be 15 min at room temperature. The column was found effective for inversion of biological samples like sugar cane juice.

    To characterize a sample of Brazilian patients with maple syrup urine disease (MSUD) diagnosed between 1992 and 2011. In this retrospective study, patients were identified through a national reference laboratory for the diagnosis of MSUD and through contact with other medical genetics services across Brazil. Data were collected by means of a chart review. Eighty-three patients from 75 families were enrolled in the study (median age, 3 years; interquartile range [IQR], 0.57-7). Median age at onset of symptoms was 10 days (IQR 5-30), whereas median age at diagnosis was 60 days (IQR 29-240, p=0.001). Only three (3.6%) patients were diagnosed before the onset of clinical manifestations. A comparison between patients with (n=12) and without (n=71) an early diagnosis shows that early diagnosis is associated with the presence of positive family history and decreased prevalence of clinical manifestations at the time of diagnosis, but not with a better outcome. Overall, 98.8% of patients have some psychomotor or neurodevelopmental delay. In Brazil, patients with MSUD are usually diagnosed late and exhibit neurological involvement and poor survival even with early diagnosis. We suggest that specific public policies for diagnosis and treatment of MSUD should be developed and implemented in the country. Copyright © 2014 Sociedade Brasileira de Pediatria.

    Plant-derived products such as date syrup (DS) have demonstrated antibacterial activity and can inhibit bacteria through numerous different mechanisms, which may be attributed to bioactive compounds including plant-derived phenolic molecules. DS is rich in polyphenols and this study hypothesized that DS polyphenols demonstrate inherent antimicrobial activity, which cause oxidative damage. This investigation revealed that DS has a high content of total polyphenols (605 mg/100 g), and is rich in tannins (357 mg/100 g), flavonoids (40.5 mg/100 g), and flavanols (31.7 mg/100 g) that are known potent antioxidants. Furthermore, DS, and polyphenols extracted from DS, the most abundant bioactive constituent of DS are bacteriostatic to both Gram positive and Gram negative Escherichia coli and Staphylococcus aureus, respectively. It has further been shown that the extracted polyphenols independently suppress the growth of bacteria at minimum inhibitory concentration (MIC) of 30 and 20 mg/mL for E. coli and S. aureus, and have observed that DS behaves as a prooxidant by generating hydrogen peroxide that mediates bacterial growth inhibition as a result of oxidative stress. At sub-lethal MIC concentrations DS demonstrated antioxidative activity by reducing hydrogen peroxide, and at lethal concentrations DS demonstrated prooxidant activity that inhibited the growth of E. coli and S. aureus. The high sugar content naturally present in DS did not significantly contribute to this effect. These findings highlight that DS’s antimicrobial activity is mediated through hydrogen peroxide generation in inducing oxidative stress in bacteria. PMID:26952177

    A male infant, who was suspected to be a case of variant form of maple syrup urine disease has been given dietary treatment since the age of 9 months. Prior to the treatment, computed tomography showed abnormally high lucidity in the cerebral white matter area with the marked narrowness in size of the frontal horn of lateral ventricles. As the treatment proceeded, clinical symptoms alleviated, and CT findings have gradually changed with the result of improved density of the white matter. 2 months after starting the treatment, however, the patient suddenly developed a hyperaminoacidemic crisis that lasted 4-5 days. Despite this hyperaminoacidemia, CT scan taken during the crisis have revealed unexpectedly normal lucidity of the white matter as well as the normal width of the frontal horn. From these findings it was concluded that markedly lucent area in CT findings prior to the treatment was not due to an acute change in serum aminoacid concentration, but rather to chronic brain edema which had insidiously and gradually developed.

    Maple syrup urine disease (MSUD) is an autosomal recessive disease associated with high levels of branched-chain amino acids. Children with MSUD can present severe neurological damage, but liver transplantation (LT) allows the patient to resume a normal diet and avoid further neurological damage. The use of living related donors has been controversial because parents are obligatory heterozygotes. We report a case of a 2-year-old child with MSUD who underwent a living donor LT. The donor was the patient's mother, and his liver was then used as a domino graft. The postoperative course was uneventful in all three subjects. DNA analysis performed after the transplantation (sequencing of the coding regions of BCKDHA, BCKDHB, and DBT genes) showed that the MSUD patient was heterozygous for a pathogenic mutation in the BCKDHB gene. This mutation was not found in his mother, who is an obligatory carrier for MSUD according to the family history and, as expected, presented both normal clinical phenotype and levels of branched-chain amino acids. In conclusion, our data suggest that the use of a related donor in LT for MSUD was effective, and the liver of the MSUD patient was successfully used in domino transplantation. Routine donor genotyping may not be feasible, because the test is not widely available, and, most importantly, the disease is associated with both the presence of allelic and locus heterogeneity. Further studies with this population of patients are required to expand the use of related donors in MSUD. PMID:24770567

  14. High fructose corn syrup induces metabolic dysregulation and altered dopamine signaling in the absence of obesity

    Science.gov (United States)

    2017-01-01

    The contribution of high fructose corn syrup (HFCS) to metabolic disorder and obesity, independent of high fat, energy-rich diets, is controversial. While high-fat diets are widely accepted as a rodent model of diet-induced obesity (DIO) and metabolic disorder, the value of HFCS alone as a rodent model of DIO is unclear. Impaired dopamine function is associated with obesity and high fat diet, but the effect of HFCS on the dopamine system has not been investigated. The objective of this study was to test the effect of HFCS on weight gain, glucose regulation, and evoked dopamine release using fast-scan cyclic voltammetry. Mice (C57BL/6) received either water or 10% HFCS solution in combination with ad libitum chow for 15 weeks. HFCS consumption with chow diet did not induce weight gain compared to water, chow-only controls but did induce glucose dysregulation and reduced evoked dopamine release in the dorsolateral striatum. These data show that HFCS can contribute to metabolic disorder and altered dopamine function independent of weight gain and high-fat diets. PMID:29287121

    2017-09-01

    Full Text Available Background: Maple syrup urine disease (MSUD is an inherited branched-chain amino acid metabolic disorder caused by the deficiency in the branched-chain alpha-keto acid dehydrogenase (BCKD complex. In MSUD, elevation of the branched-chain amino acids, such as alpha-keto acid and alpha-hydroxy acid, occurs due to the BCKDC gene deficiency, appearing in the blood, urine, and cerebrospinal fluid, which leads to neurological damage and mental retardation. MSUD phenotypically penetrates due to the mutations in the coding genes of four subunits of the BCKD complex, including the BCKDHA, BCKDHB, DBT, and DLD genes.Case report: We aimed to report the cases of three families whose children were affected by MSUD and presented with symptomatic features during the first week of birth, which were identified by mass spectrometry. DNA study was performed as a diagnosis panel containing four encoded BCKDC subunit genes.Conclusion: In the current study, DNA analysis and phenotypic manifestations indicated a novel mutation of c.143delT, p.L48Rfs*15 in the BCKDHA gene in a homozygous state, which is a causative mutation for the classic MSUD phenotype. Early diagnosis and neonatal screening are recommended for the accurate and effective treatment of this disease

    Maple syrup urine disease (MSUD) is an autosomal recessive disorder caused by a blockage of branched-chain keto acid of BCAA (branched-chain keto acid dehydrogenase, BCKDH) leading to neurological damage induced by accumulation of leucine and metabolites. MSUD expenditure and energy requirement information is limited. To determine if basal/total energy expenditure (BEE/TEE) is comparable between different determination methods and if values agree with recommendations of energy in MSUD children, and whether they relate to nutritional status. Case-control study between MSUD (n = 16) and healthy children (n = 11) aged 6-18 years. Current nutritional status, physical activity level, body composition by DEXA and BEE/TEE by indirect calorimetry (BEEr) and predictive equations (FAO/WHO/ONU - WHO - and Schofield) were assessed; STATA 2013 (p < 0.05). When comparing the energy expenditure variables, there was no significant difference between groups. Moreover, compared to BEEr, equations underestimate according to BEE WHO and Schofield, respectively (P = 0.00; 0.02). The WHO equation had lower average calorie difference, greater concordance correlation and association with indirect calorimetry compared to the Schofield equation for both groups, being the best predictor of the BEE for MSUD group. Energy recommendations for MSUD children are according to energy expenditure; thus the use of WHO equation is a clinically and statistically feasible tool for its determination.

    Maple syrup urine disease (MSUD) is an inborn error of amino acid metabolism, which affects the brain tissue resulting in impairment or death if untreated. Imaging studies have shown reversible brain edema during acute metabolic decompensation. The purpose of this paper is to describe the diffusion-weighted imaging (DWI) and spectroscopy findings during metabolic decompensation and to assess the value of these findings in the prediction of patient outcome. Six patients with the diagnosis of MSUD underwent conventional MR imaging with DWI during acute presentation with metabolic decompensation. Spectroscopy with long TE was performed in four of the six patients. Follow-up examinations were performed after clinical and metabolic recovery. DWI demonstrated marked restriction of proton diffusion compatible with cytotoxic or intramyelinic sheath edema in the brainstem, basal ganglia, thalami, cerebellar and periventricular white matter and the cerebral cortex. This was accompanied by the presence of an abnormal branched-chain amino acids (BCAA) and branched-chain alpha-keto acids (BCKA) peak at 0.9 ppm as well as elevated lactate on proton spectroscopy in all four patients. The changes in all six patients were reversed with treatment without evidence of volume loss or persistent tissue damage. The presence of cytotoxic or intramyelinic edema as evidenced by restricted water diffusion on DWI, with the presence of lactate on spectroscopy, could imply imminent cell death. However, in the context of metabolic decompensation in MSUD, it appears that changes in cell osmolarity and metabolism can reverse completely after metabolic correction. (orig.)

    Maple syrup urine disease (MSUD) is an inborn error of amino acid metabolism, which affects the brain tissue resulting in impairment or death if untreated. Imaging studies have shown reversible brain edema during acute metabolic decompensation. The purpose of this paper is to describe the diffusion-weighted imaging (DWI) and spectroscopy findings during metabolic decompensation and to assess the value of these findings in the prediction of patient outcome. Six patients with the diagnosis of MSUD underwent conventional MR imaging with DWI during acute presentation with metabolic decompensation. Spectroscopy with long TE was performed in four of the six patients. Follow-up examinations were performed after clinical and metabolic recovery. DWI demonstrated marked restriction of proton diffusion compatible with cytotoxic or intramyelinic sheath edema in the brainstem, basal ganglia, thalami, cerebellar and periventricular white matter and the cerebral cortex. This was accompanied by the presence of an abnormal branched-chain amino acids (BCAA) and branched-chain alpha-keto acids (BCKA) peak at 0.9 ppm as well as elevated lactate on proton spectroscopy in all four patients. The changes in all six patients were reversed with treatment without evidence of volume loss or persistent tissue damage. The presence of cytotoxic or intramyelinic edema as evidenced by restricted water diffusion on DWI, with the presence of lactate on spectroscopy, could imply imminent cell death. However, in the context of metabolic decompensation in MSUD, it appears that changes in cell osmolarity and metabolism can reverse completely after metabolic correction.

    Glucose isomerase is the important enzyme for the production of high fructose corn syrup (HFCS). One-step production of HFCS containing more than 55% fructose (HFCS-55) is receiving much attention for its industrial applications. In this work, the Escherichia coli harboring glucose isomerase mutant TEGI-W139F/V186T was immobilized for efficient production of HFCS-55. The immobilization conditions were optimized, and the maximum enzyme activity recovery of 92% was obtained. The immobilized glucose isomerase showed higher pH, temperature, and operational stabilities with a K m value of 272 mM and maximum reaction rate of 23.8 mM min -1 . The fructose concentration still retained above 55% after the immobilized glucose isomerase was reused for 10 cycles, and more than 85% of its initial activity was reserved even after 15 recycles of usage at temperature of 90 °C. The results highlighted the immobilized glucose isomerase as a potential biocatalyst for HFCS-55 production.

    In an effort to increase harmonization of care and enable outcome studies, the Genetic Metabolic Dietitians International (GMDI) and the Southeast Regional Newborn Screening and Genetics Collaborative (SERC) are partnering to develop nutrition management guidelines for inherited metabolic disorders (IMD) using a model combining both evidence- and consensus-based methodology. The first guideline to be completed is for maple syrup urine disease (MSUD). This report describes the methodology used in its development: formulation of five research questions; review, critical appraisal and abstraction of peer-reviewed studies and unpublished practice literature; and expert input through Delphi surveys and a nominal group process. This report includes the summary statements for each research question and the nutrition management recommendations they generated. Each recommendation is followed by a standardized rating based on the strength of the evidence and consensus used. The application of technology to build the infrastructure for this project allowed transparency during development of this guideline and will be a foundation for future guidelines. Online open access of the full, published guideline allows utilization by health care providers, researchers, and collaborators who advise, advocate and care for individuals with MSUD and their families. There will be future updates as warranted by developments in research and clinical practice. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

    Full Text Available Introduction. Maple syrup urine disease (MSUD is an inborn error of branched chain amino acids (BCAAs metabolism. We report an infant with MSUD who developed 2 episodes of cutaneous lesions as a result of isoleucine deficiency and zinc deficiency, respectively. Case Presentation. A 12-day-old male infant was presented with poor milk intake and lethargy. The diagnosis of MSUD was made based on clinical and biochemical data. Management and Outcome. Specific dietary restriction of BCAAs was given. Subsequently, natural protein was stopped as the patient developed hospital-acquired infections which resulted in an elevation of BCAAs. Acrodermatitis dysmetabolica developed and was confirmed to be from isoleucine deficiency. At the age of 6 months, the patient developed severe lethargy and was on natural protein exclusion for an extended period. Despite enteral supplementation of zinc sulfate, cutaneous manifestations due to zinc deficiency occurred. Discussion. Skin lesions in MSUD patients could arise from multiple causes. Nutritional deficiency including isoleucine and zinc deficiencies can occur and could complicate the treatment course as a result of malabsorption, even while on enteral supplementation. Parenteral nutrition should be considered and initiated accordingly. Clinical status, as well as BCAA levels, should be closely monitored in MSUD patients.

    High-fructose corn syrup-55 (HFCS-55) has been suggested to be more lipogenic than sucrose, which increases the risk for nonalcoholic fatty liver disease (NAFLD) and dyslipidemia. The study objectives were to determine the effects of drinking different sugar-sweetened solutions on hepatic gene expression in relation to liver fatty acid composition and risk of NAFLD. Female rats were randomly assigned (n=7 rats/group) to drink water or water sweetened with 13% (w/v) HFCS-55, sucrose or fructose for 8 weeks. Rats drinking HFCS-55 solution had the highest (P=.03) hepatic total lipid and triglyceride content and histological evidence of fat infiltration. Rats drinking HFCS-55 solution had the highest hepatic de novo lipogenesis indicated by the up-regulation of stearoyl-CoA desaturase-1 and the highest (Ptriglyceride-rich lipoprotein from the liver was increased as shown by up-regulation of gene expression of microsomal triglyceride transfer protein in rats drinking sucrose, but not HFCS-55 solution. The observed lipogenic effects were attributed to the slightly higher fructose content of HFCS-55 solution in the absence of differences in macronutrient and total caloric intake between rats drinking HFCS-55 and sucrose solution. Results from gene expression and fatty acid composition analysis showed that, in a hypercaloric state, some types of sugars are more detrimental to the liver. Based on these preclinical study results, excess consumption of caloric sweetened beverage, particularly HFCS-sweetened beverages, should be limited. Published by Elsevier Inc.

    Bioactive components such as polyphenols, present in many plants, are purported to have anti-inflammatory and antiangiogenic properties. Date syrup, produced from date fruit of the date palm tree, has traditionally been used to treat a wide range of diseases with etiologies involving angiogenesis and inflammation. It was hypothesized that polyphenols in date syrup reduce angiogenic responses such as cell migration, tube formation, and matrix metalloproteinase activity in an inflammatory model by exhibiting anti-inflammatory activity mediated by vascular endothelial growth factor (VEGF) and the prostaglandin enzyme cyclooxygenase-2 (COX-2) in endothelial cells. Date syrup polyphenols at 60 and 600μg/mL reduced inflammation and suppressed several stages of angiogenesis, including endothelial cell migration, invasion, matrix metalloproteinase activity, and tube formation, without evidence of cytotoxicity. VEGF and COX-2 expression induced by tumor necrosis factor-alpha at both gene expression and protein level was significantly reduced by date syrup polyphenols in comparison to untreated cells. In conclusion, polyphenols in date syrup attenuated angiogenic responses and exhibited anti-inflammatory activity mediated by VEGF and COX-2 expression in endothelial cells.

    The primary objective was to assess the warming sensation caused by flavor 316282 in a cold and cough product in the target population. A single-cohort, single-treatment arm, open-label study. Subjects received one 30-mL dose of syrup containing flavor 316282, paracetamol, phenylephrine hydrochloride, and guaifenesin and recorded onset and disappearance of any warming sensation in the mouth/throat. Subjects' assessment of strength and appeal of the sensation, taste, texture, and acceptability of the product as a cold and cough remedy was investigated using questionnaires. A total of 51 subjects were included; 47 (92.1%) experienced a warming sensation. The median duration of the warming sensation was 100 s (95% confidence interval = 82 s, 112 s). The majority of subjects rated the syrup as excellent, good, or fair for treatment of cough and cold symptoms (96.1%), taste (80.4%), and texture (98.0%). There were no safety concerns, and the syrup was well tolerated. Most subjects liked the warming sensation. Flavor 316282 in a cold and cough syrup is associated with a warming sensation. The syrup is well tolerated, safe, and palatable.

    Maple syrup production is an important economic activity in north-eastern North-America. The beginning and length of the production season is linked to daily variation in temperature. There are increasing concerns about the potential impact of climatic change on this industry. Here, we used weekly data of syrup yield for the 1999–2011 period from 121 maple stands in 11 regions of Québec (Canada) to predict how the period of production may be impacted by climate warming. The date at which the production begins is highly variable between years with an average range of 36 days among the regions. However, the average start date for a given region, which ranged from Julian day 65 to 83, was highly predictable (r2 = 0.88) using the average temperature from January to April (TJ-A). A logistic model predicting the weekly presence or absence of production was also developed. Using the inputs of 77 future climate scenarios issued from global models, projections of future production timing were made based on average TJ-A and on the logistic model. The projections of both approaches were in very good agreement and suggest that the sap season will be displaced to occur 15–19 days earlier on average in the 2080–2100 period. The data also show that the displacement in time will not be accompanied by a greater between years variability in the beginning of the season. However, in the southern part of Québec, very short periods of syrup production due to unfavourable conditions in the spring will occur more frequently in the future although their absolute frequencies will remain low.

    To evaluate the stability of an extemporaneously prepared 7% chloral hydrate syrup under different conditions of storage and dispensing. Three batches of 7% chloral hydrate syrup were prepared. Each batch was stored in 50 light-resistant glass containers of 60 mL with child-resistant caps and in two bottles of 1000 mL to simulate two forms of dispensing, mono and multi-dose, respectively. Twenty five mono-dose bottles and a multi-dose bottle of each batch were stored under room conditions (20 ± 1 °C) and the rest of the samples were stored in the fridge (5 ± 2 °C). The physical, chemical and microbiological stability was evaluated for 180 days. Stability was defined as retention of at least 95% of the initial concentration of chloral hydrate, the absence of both visible particulate matter, or color and/or odor changes and the compliance with microbiological attributes of non-sterile pharmaceutical products. At least 98% of the initial chloral hydrate concentration remained throughout the 180-day study period. There were no detectable changes in color, odor, specific gravity and pH and no visible microbial growth. These results were not affected by storage, room or refrigeration conditions or by the frequent opening or closing of the multi-dose containers. Extemporaneously compounded 7% chloral hydrate syrup was stable for at least 180 days when stored in mono or multi-dose light-resistant glass containers at room temperature and under refrigeration.

    The aim of the study was to evaluate indications, results, and clinical and neurological evolution in children who have undergone liver transplantation for classical maple syrup urine disease (MSUD). Descriptive study of liver transplantation for MSUD between 1991 and 2012. Eight patients were transplanted. Indications for transplant were poor metabolic control expressed as significant psychomotor disabilities (4 had psychomotor delays, 5 had spasticity, and 5 had epilepsy) and poor quality of life (mean number of acute metabolic decompensations and mean number of total hospitalizations before transplantation 5 and 12, respectively). Four required nasogastric tube, with a maximum 4 g/day protein-restricted diet in all of them. Seven sustained significant alterations in brain magnetic resonance imaging. Mean leucine and alloisoleucine levels were 608 (standard deviation [SD] 516) and 218 μmol/L (SD 216), respectively. All of the patients received transplants with deceased-donor livers, with ages between 1.5 and 2.5 years (mean 1.78 years). Mean posttransplantation follow-up period was 12.2 years (range 5-21 years). Final patient and graft survival was 87.5% and 75%, respectively. Following transplantation, none required hospitalization in the last 3 years nor did any have new acute metabolic decompensations following a normal diet. Five followed normal schooling, 2 had motor disabilities, and 2 had convulsive crises. Brain magnetic resonance imaging was taken in 4 patients, showing neuroimage improvement in 3 of them. Mean leucine levels were <350 μmol/L from the immediate posttransplantation period (mean 225 μmol/L, SD 78), with a maximum alloisoleucine level of 20 μmol/L. Liver transplantation is an effective treatment for classical MSUD that arrests brain damage, although it does not reverse the process.

    Maple syrup urine disease (MSUD) is an inherited disorder of branched chain ketoacid (BCKA) oxidation associated with episodic and chronic brain disease. Transplantation of liver from an unrelated deceased donor restores 9-13% whole-body BCKA oxidation capacity and stabilizes MSUD. Recent reports document encouraging short-term outcomes for MSUD patients who received a liver segment from mutation heterozygous living related donors (LRDT). To investigate effects of living related versus deceased unrelated grafts, we studied four Brazilian MSUD patients treated with LRDT who were followed for a mean 19 ± 12 postoperative months, and compared metabolic and clinical outcomes to 37 classical MSUD patients treated with deceased donor transplant. Patient and graft survival for LRDT were 100%. Three of 4 MSUD livers were successfully domino transplanted into non-MSUD subjects. Following LRDT, all subjects resumed a protein-unrestricted diet as mean plasma leucine decreased from 224 ± 306 μM to 143 ± 44 μM and allo-isoleucine decreased 91%. We observed no episodes of hyperleucinemia during 80 aggregate postoperative patient-months. Mean plasma leucine:isoleucine:valine concentration ratios were ~2:1:4 after deceased donor transplant compared to ~1:1:1.5 following LRDT, resulting in differences of predicted cerebral amino acid uptake. Mutant heterozygous liver segments effectively maintain steady-state BCAA and BCKA homeostasis on an unrestricted diet and during most catabolic states, but might have different metabolic effects than grafts from unrelated deceased donors. Neither living related nor deceased donor transplant affords complete protection from metabolic intoxication, but both strategies represent viable alternatives to nutritional management.

    Maple syrup urine disease (MSUD) is a disorder of branched-chain amino acids (BCAA). The defect in the branched-chain α-keto acid dehydrogenase complex activity leads to an accumulation of these compounds and their corresponding α-keto-acids and α-hydroxy-acids. Studies have shown that oxidative stress may be involved in neuropathology of MSUD. L-carnitine (L-car), which has demonstrated an important role as antioxidant by reducing and scavenging free radicals formation and by enhancing the activity of antioxidant enzymes, have been used in the treatment of some metabolic rare disorders. This study evaluated the oxidative stress parameters, di-tyrosine, isoprostanes and antioxidant capacity, in urine of MSUD patients under protein-restricted diet supplemented or not with L-car capsules at a dose of 50 mg kg(-1) day(-1). It was also determined urinary α-keto isocaproic acid levels as well as blood free L-car concentrations in blood. It was found a deficiency of carnitine in patients before the L-car supplementation. Significant increases of di-tyrosine and isoprostanes, as well as reduced antioxidant capacity, were observed before the treatment with L-car. The L-car supplementation induced beneficial effects on these parameters reducing the di-tyrosine and isoprostanes levels and increasing the antioxidant capacity. It was also showed a significant increase in urinary of α-ketoisocaproic acid after 2 months of L-car treatment, compared to control group. In conclusion, our results suggest that L-car may have beneficial effects in the treatment of MSUD by preventing oxidative damage to the cells and that urine can be used to monitorize oxidative damage in patients affected by this disease.

    There is growing evidence that intakes of high-fructose corn syrup (HFCS), HFCS-sweetened soda, fruit drinks and apple juice - a high-fructose 100 % juice - are associated with asthma, possibly because of the high fructose:glucose ratios and underlying fructose malabsorption, which may contribute to enteral formation of pro-inflammatory advanced glycation end products, which bind receptors that are mediators of asthma. Cox proportional hazards models were used to assess associations between intakes of these beverages and asthma risk, with data from the Framingham Offspring Cohort. Diet soda and orange juice - a 100 % juice with a 1:1 fructose:glucose ratio - were included for comparison. Increasing intake of any combination of HFCS-sweetened soda, fruit drinks and apple juice was significantly associated with progressively higher asthma risk, plateauing at 5-7 times/week v. never/seldom, independent of potential confounders (hazard ratio 1·91, P<0·001). About once a day consumers of HFCS-sweetened soda had a 49 % higher risk (P<0·011), moderate apple juice consumers (2-4 times/week) had a 61 % higher risk (P<0·007) and moderate fruit drink consumers had a 58 % higher risk (P<0·009), as compared with never/seldom consumers. There were no associations with diet soda/orange juice. These associations are possibly because of the high fructose:glucose ratios, and fructose malabsorption. Recommendations to reduce consumption may be inadequate to address asthma risk, as associations are evident even with moderate intake of these beverages, including apple juice - a 100 % juice. The juice reductions in the US Special Supplemental Nutrition Program for Women, Infants, and Children in 2009, and the plateauing/decreasing asthma prevalence (2010-2013), particularly among non-Hispanic black children, may be related. Further research regarding the consequences of fructose malabsorption is needed.

    Full Text Available Background and objectives: Cancer-related fatigue (CRF is the most common and distressing symptom that affects overall quality of life of cancer patients. Due to the multi-factorial etiology, there is currently no “gold standard” for treatment of CRF. Considering the growing importance of national traditional medicines, natural remedies are viewed as playing distinctive role. “Jollab” is a natural syrup prescribed by Iranian traditional medicine (ITM scholars as tonic especially for the cardiovascular system. “Jollab” can consist of several ingredients although almost all traditional recipes include saffron and rose water as well as sugar or honey. The aim of this research was to develop a honey based “Jollab” and evaluate hydroxymethylfurfural (HMF, a product of fructose decomposition, as an indicator of heating effect on honey. Methods: Several “Jollab” formulations with different proportions of honey and rose water were prepared using deslagging procedure through direct or indirect heating. The HMF content of the formulation was measured according to International Honey Commission (IHC method. Results: “Jollab” was formulated with saffron (0.1%, honey (57.1% and rose water (42.8%. Two-thirds of the rose water was evaporated during deslagging procedure through direct heating (up to 95 °C and the remaining was added to the honey at the end of the process. Moreover, the HMF content of the prepared Jollab was 64.47±5.49 mg/kg which meets ICH standards. Conclusion: The developed honey based Jollab could be considered as a safe formulation for further studies in the field of CRF due to the acceptable HMF content.

    Background Research on trends in consumption of added sugar and high fructose corn syrup (HFCS) in the U.S. has largely focused on calorically-sweetened beverages, ignoring other sources. Objective To examine U.S. consumption of added sugar and HFCS to determine long-term trends in availability and intake from beverages and foods. Design We used two estimation techniques and data from the Nationwide Food Consumption Surveys (1965 and 1977), Continuing Survey of Food Intake in Individuals (1989–1991) and the National Health and Nutrition Examination Surveys (1999–2000, 2001–2002 and 2003–2004) to examine trends in HFCS and added sugar, including: (a) overall trends, and (b) within certain food and beverage groups. Results Availability and consumption of HFCS and added sugar increased over time until a slight decline between 2000 and 2004. By 2004, HFCS provided roughly 8% of total energy intake compared to total added sugar of 377 kcal/person/d, accounting for 17% of total energy intake. While food and beverage trends were similar, soft drinks and fruit drinks provided the most HFCS (158 and 40 kcal/person/d in 2004, respectively). Moreover, among the top 20% of individuals, 896 kcal/person/d of added sugar was consumed compared to 505 kcal/person/d of HFCS. Among consumers, sweetened tea and desserts also represented major contributors of calories from added sugar (over 100 kcal/person/d). Conclusion While increased intake of calories from HFCS is important to examine, the health affect of overall trends in added caloric sweeteners should not be overlooked. PMID:19064537

    Lotus ( Nelumbo nucifera ) root has been used as an edible vegetable in East Asia for thousands of years. The present research was aimed to explore the physicochemical, nutritional and microbiological safety of lotus root fermented sugar syrup as a fermented food supplement or condiment for human health benefits. In this study, the physicochemical, nutritional and microbiological safety properties of lotus root syrup fermented with 57° Brix brown sugar at different time periods until 6 months (180 days) was investigated. There was a significant improvement as compared to 57° Brix brown sugar broth (as a control) in the total acceptability and physicochemical properties of lotus root sugar syrup samples such as pH and color improvement. The red color values of 180 days lotus root fermented sugar syrup samples were significantly enhanced (6.85 ± 0.58) when compared with the control (0.20 ± 0.15). In addition, the total protein content was increased from 8.27 ± 0.86 to 392.33 ± 7.19 μg/mL, along with the increase in fermentation time reaching to the level of consumption acceptability. All the lotus root fermented sugar syrup samples were subjected to microbiological analysis. It was found that the coliform, Bacillus cereus , Escherichia coli , Salmonella and Staphylococcus aureus counts were not detected in majority of the samples, confirming the high degree of hygiene processing of lotus root fermented sugar syrup samples for its use as a food supplement or condiment.

    About half of worldwide production of dates is unconsumed. Dates contain over 75 % reduced sugars (mostly glucose and fructose with nearly equal amount). Compared to the commercial Saccharomyces cerevisiae wild strain, the strains ATCC 36858 and 36859 could produce high concentration fructose syrups. The fructose fractions obtained were 95.9 and 97.4% for ATCC 36858 and 86.5 and 91.4% for ATCC 36859 at 30 and 33°C, respectively. Fructose yields higher than 90% were obtained using ATCC 36858 compared to those obtained using ATCC 36859 which were 87.3 and 66.1% at 30 and 33°C, respectively. The ethanol yield using ATCC 36858 was higher than that using ATCC 36859 by 16 and 9% at 30 and 33°C, respectively. Through this finding, the production of fructose and ethanol from date extract is a promising process. Moreover, the fructose fractions obtained here (about 90%) are much higher than those obtained with the commercial process, i.e. 55 % fructose syrups.

    2016-01-01

    Full Text Available Fructose corn syrup is cheap sweetener and prolongs the shelf life of products, but fructose intake causes hyperinsulinemia, hypertriglyceridemia, and hypertension. All of them are referred to as metabolic syndrome and they are risk factors for cardiovascular diseases. Hence, the harmful effects of increased fructose intake on health and their prevention should take greater consideration. Caffeic Acid Phenethyl Ester (CAPE has beneficial effects on metabolic syndrome and vascular function which is important in the prevention of cardiovascular disease. However, there are no known studies about the effect of CAPE on fructose-induced vascular dysfunction. In this study, we examined the effect of CAPE on vascular dysfunction due to high fructose corn syrup (HFCS. HFCS (6 weeks, 30% fed with drinking water caused vascular dysfunction, but treatment with CAPE (50 micromol/kg i.p. for the last two weeks effectively restored this problem. Additionally, hypertension in HFCS-fed rats was also decreased in CAPE supplemented rats. CAPE supplements lowered HFCS consumption-induced raise in blood glucose, homocysteine, and cholesterol levels. The aorta tissue endothelial nitric oxide synthase (eNOS production was decreased in rats given HFCS and in contrast CAPE supplementation efficiently increased its production. The presented results showed that HFCS-induced cardiovascular abnormalities could be prevented by CAPE treatment.

    Fructose corn syrup is cheap sweetener and prolongs the shelf life of products, but fructose intake causes hyperinsulinemia, hypertriglyceridemia, and hypertension. All of them are referred to as metabolic syndrome and they are risk factors for cardiovascular diseases. Hence, the harmful effects of increased fructose intake on health and their prevention should take greater consideration.

    The dietary energy for broiler chicken is provided through the inclusion of cereal grains and vegetable oil in the ration. The cost of corn is increasing exponentially, whereas sugar syrup (SS) is available with reasonable cost. Sugar syrup can be used as a substitute for starch/grains and vegetable oil. No research has been reported on the effect of SS on broiler meat quality. In this study, Hubbard commercial broiler chicks were fed a control basal diet (corn-soy basal diet on an ad libitum basis) alone or with graded levels of SS. A completely randomized design with 3 replications (n = 3, treatments = 4 with 4 subsamples per treatment) were used to investigate the effect of replacing part of the corn and oil in broiler chicken rations with graded levels of SS (5, 10, and 15%) on breast and thigh meat quality (proximate analysis, cooking loss, instrumental color, and texture and sensory properties). Rations containing up to 15% SS had a slight effect on proximate composition of raw and cooked broiler breast and thigh meats. Cooking loss of thigh meat decreased significantly with increasing SS but increased significantly for breast meats. No significant differences were detected (P > 0.05) among breast or thigh meats fed rations with a different level of SS on all sensory properties, except that cooked thigh meat had a slightly harder texture. Overall, results suggest that feeding broilers with SS rations (up to 15%) produced high-quality breast and thigh meats with minimal differences.

    Full Text Available In recent years production and usage of functional food and drinks is one of the public and scientist’s interest. Since carbohydrates have been recognizedas the major calorie source in many food baskets, most attention has been focused on substitution of sucrose with non-caloric sweeteners. Although both natural and synthetic sweeteners have been used in the formulation of food stuffs, deep concern is raised regarding safety aspects of synthetic ones. Stevia is a natural suitable sweetener that is currently being used as a substitute for sugar in many dietary and functional foods and drinks. In the present study the effect of using stevia sugar as a replacement for sucrose in the preparation of saffron beverages was investigated. Accordingly, saffron syrup was prepared with 5 treatments in which100%, 75%, 50%, 25% and 0% of stevia sugar replaced sucrose. Then, the physicochemical, rheological and sensory properties of saffron functional syrup were investigated. The results indicated that by increasing stevia brix level, density and viscosity increased but the syrups’ pH decreases. The best treatment was the sample containing 25% steviaand 75% sucrose that compared to other samples regarding sensory characteristics had a higher acceptance by consumer and regarding physicochemical and rheological characteristics more similar to the control sample.

  5. Lactoferrin dampens high-fructose corn syrup-induced hepatic manifestations of the metabolic syndrome in a murine model.

    Directory of Open Access Journals (Sweden)

    Yi-Chieh Li

    Full Text Available Hepatic manifestations of the metabolic syndrome are related obesity, type 2 diabetes/insulin resistance and non-alcoholic fatty liver disease. Here we investigated how the anti-inflammatory properties of lactoferrin can protect against the onset of hepatic manifestations of the metabolic syndrome by using a murine model administered with high-fructose corn syrup. Our results show that a high-fructose diet stimulates intestinal bacterial overgrowth and increases intestinal permeability, leading to the introduction of endotoxin into blood circulation and liver. Immunohistochemical staining of Toll-like receptor-4 and thymic stromal lymphopoietin indicated that lactoferrin can modulate lipopolysaccharide-mediated inflammatory cascade. The important regulatory roles are played by adipokines including interleukin-1β, interleukin-6, tumor necrosis factor-α, monocyte chemotactic protein-1, and adiponectin, ultimately reducing hepatitis and decreasing serum alanine aminotransferase release. These beneficial effects of lactoferrin related to the downregulation of the lipopolysaccharide-induced inflammatory cascade in the liver. Furthermore, lactoferrin reduced serum and hepatic triglycerides to prevent lipid accumulation in the liver, and reduced lipid peroxidation, resulting in 4-hydroxynonenal accumulation. Lactoferrin reduced oral glucose tolerance test and homeostasis model assessment-insulin resistance. Lactoferrin administration thus significantly lowered liver weight, resulting from a decrease in the triglyceride and cholesterol synthesis that activates hepatic steatosis. Taken together, these results suggest that lactoferrin protected against high-fructose corn syrup induced hepatic manifestations of the metabolic syndrome.

    Combinatorial peptide ligand libraries, both commercial and home-made, have been adopted to investigate the proteome of non-alcoholic beverages, in order to assess their genuineness and detect also trace proteins, in search of potential allergens. Two such beverages have been studied: almond milk and orgeat syrup. In the first product we have been able to identify 132 unique protein species, the deepest investigation so far of the almond proteome. In the second beverage, a handful of proteins (just 14) have been detected, belonging to a bitter almond extract. In both cases, the genuineness of such products has been verified, as well as the fact that almond milk, judging on the total protein and fat content, must have been produced with 100g ground almonds per litre of beverage, as required by authorities. On the contrary, cheap orgeat syrups produced by local supermarkets and sold as their own brands, where found not to contain any residual proteins, suggesting that they contained only synthetic aromas and no natural plant extracts. This could be the starting point for investigating the myriad of beverages that in the last decades have invaded the shelves of supermarkets the world over, whose genuineness and natural origin have never been properly assessed.

    About half of worldwide production of dates is unconsumed. Dates contain over 75 % reduced sugars (mostly glucose and fructose with nearly equal amount). Compared to the commercial Saccharomyces cerevisiae wild strain, the strains ATCC 36858 and 36859 could produce high concentration fructose syrups. The fructose fractions obtained were 95.9 and 97.4% for ATCC 36858 and 86.5 and 91.4% for ATCC 36859 at 30 and 33°C, respectively. Fructose yields higher than 90% were obtained using ATCC 36858 compared to those obtained using ATCC 36859 which were 87.3 and 66.1% at 30 and 33°C, respectively. The ethanol yield using ATCC 36858 was higher than that using ATCC 36859 by 16 and 9% at 30 and 33°C, respectively. Through this finding, the production of fructose and ethanol from date extract is a promising process. Moreover, the fructose fractions obtained here (about 90%) are much higher than those obtained with the commercial process, i.e. 55 % fructose syrups.

    Maple syrup is made by boiling the sap collected from certain maple (Acer) species. During this process, phytochemicals naturally present in tree sap are concentrated in maple syrup. We previously reported 23 phytochemicals from a butanol extract of Canadian maple syrup (MS-BuOH). Here we report the isolation and identification of 30 additional compounds (1–30) from its ethyl acetate extract (MS-EtOAc) not previously reported from MS-BuOH. Of these, 4 compounds are new (1–3, 18) and 20 compounds (4–7, 10–12, 14–17, 19–20, 22–24, 26, 28–30) are being reported from maple syrup for the first time. The new compounds include 3 lignans and 1 phenylpropanoid: 5-(3″,4″-dimethoxyphenyl)-3-hydroxy-3-(4′-hydroxy-3′-methoxybenzyl)-4-hydroxymethyl-dihydrofuran-2-one (1), (erythro, erythro)-1-[4-[2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3,5-dimethoxyphenyl]-1,2,3-propanetriol (2), (erythro, threo)-1-[4-[2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3,5-dimethoxyphenyl]-1,2,3-propanetriol (3) and 2,3-dihydroxy-1-(3,4-dihydroxyphenyl)-1-propanone (18), respectively. In addition, 25 other phenolic compounds were isolated including (threo, erythro)-1-[4-[(2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3-methoxyphenyl]-1,2,3-propanetriol (4), (threo, threo)-1-[4-[(2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethoxy]-3-methoxyphenyl]-1,2,3-propanetriol (5), threo-guaiacylglycerol-β-O-4′-dihydroconiferyl alcohol (6), erythro-1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxypropyl)-2,6-dimethoxyphenoxy]-1,3-propanediol (7), 2-[4-[2,3-dihydro-3-(hydroxymethyl)-5-(3-hydroxypropyl)-7-methoxy-2-benzofuranyl]-2,6-dimethoxyphenoxy]-1-(4-hydroxy-3-methoxyphenyl)-1,3-propanediol (8), acernikol (9), leptolepisol D (10), buddlenol E (11), (1S,2R)-2-[2,6-dimethoxy-4-[(1S,3aR,4S,6aR)-tetrahydro-4-(4-hydroxy-3,5-dimethoxyphenyl)-1H,3H-furo[3,4-c]furan-1-yl]phenoxy]-1-(4-hydroxy-3-methoxyphenyl)-1

    Branched-chain ketoacid dehydrogenase deficiency results in complex and volatile metabolic derangements that threaten brain development. Treatment for classical maple syrup urine disease (MSUD) should address this underlying physiology while also protecting children from nutrient deficiencies. Based on a 20-year experience managing 79 patients, we designed a study formula to (1) optimize transport of seven amino acids (Tyr, Trp, His, Met, Thr, Gln, Phe) that compete with branched-chain amino acids (BCAAs) for entry into the brain via a common transporter (LAT1), (2) compensate for episodic depletions of glutamine, glutamate, and alanine caused by reverse transamination, and (3) correct deficiencies of omega-3 essential fatty acids, zinc, and selenium widespread among MSUD patients. The formula was enriched with LAT1 amino acid substrates, glutamine, alanine, zinc, selenium, and alpha-linolenic acid (18:3n-3). Fifteen Old Order Mennonite children were started on study formula between birth and 34 months of age and seen at least monthly in the office. Amino acid levels were checked once weekly and more often during illnesses. All children grew and developed normally over a period of 14-33 months. Energy demand, leucine tolerance, and protein accretion were tightly linked during periods of normal growth. Rapid shifts to net protein degradation occurred during illnesses. At baseline, most LAT1 substrates varied inversely with plasma leucine, and their calculated rates of brain uptake were 20-68% below normal. Treatment with study formula increased plasma concentrations of LAT1 substrates and normalized their calculated uptakes into the nervous system. Red cell membrane omega-3 polyunsaturated fatty acids and serum zinc and selenium levels increased on study formula. However, selenium and docosahexaenoic acid (22:6n-3) levels remained below normal. During the study period, hospitalizations decreased from 0.35 to 0.14 per patient per year. There were 28 hospitalizations

    Among the many factors influencing the complex process of lava flow emplacement, the interaction with the substrate onto which flow is emplaced plays a central role. Lava flows are rarely emplaced onto smooth or regular surfaces. For example, at Kīlauea Volcano, Hawai'i, lava flows regularly flow over solid rock, vegetation, basaltic or silica sand, and man-made materials, including asphalt and concrete. In situ studies of lava-substrate interactions are inherently difficult, and often dangerous, to carry-out, requiring the design of controllable laboratory experiments. We investigate the effects of substrate grain size, cohesion, and roughness on flow mobility and morphology through a series of flow experiments using analog materials and molten basalt. We have developed a series of experiments that allow for adjustable substrate parameters and analyze their effects on lava flow emplacement. The first set of experiments are performed at the Fluids Mechanics Laboratory at the Lamont-Doherty Earth Observatory and focus on two analog materials: polyethylene glycol (PEG), a commercially available wax, and corn syrup. The fluids were each extruded onto a series of scaled substrate beds to replicate the emplacement of lava in a natural environment. Preliminary experiments demonstrated that irregular topography, particularly topography with a height amplitude similar to that of the flow itself, can affect flow morphology, width, and velocity by acting as local barriers or culverts to the fluid. This is expected from observations of fluid flow in natural environments. A follow-up set of experiments will be conducted in Fall 2015 at the Syracuse University (SU) Lava Project Lab. In this set, we will pour molten basalt directly onto a series of substrates representing natural environments found on the Earth and other rocky bodies in the Solar System. These experiments will allow for analysis of the effects of basaltic composition and high temperatures on lava-substrate heat

    Spoilage of chocolate pralines, due to growth of microorganisms tolerating low water activity, causes problems in the confectionary industry. Therefore, an increased knowledge on which organisms are present in the chocolate fillings and their tolerance towards low aw, pH, ethanol and other preservatives is needed. Using media containing 40-50% glucose (aw 0.872-0.925) bacteria, yeasts and moulds were isolated from chocolate pralines (aw 0.70-0.898) of nine manufactures and sugar syrups (aw 0.854) used as ingredient in chocolate praline production by one of the manufacturers. Isolates were identified by conventional microbiological analyses and by sequencing of their 16S rRNA, 26S rRNA (D1/D2-region) or calmodulin genes. Further, for several species the identity was confirmed by amplification and sequencing of additional genes. In total 677 isolates were identified as belonging to ten different bacteria species, six yeast species and ten mould species with yeast being the most frequently isolated. Bacteria and moulds were found in low numbers, whereas yeast were found in numbers up to 10(7)CFU/g. The most frequently isolated yeast, bacteria and moulds belonged to the species of Zygosaccharomyces rouxii, Bacillus subtilis and Aspergillus terreus, respectively. Fifteen isolates were screened for their ability to grow in presence of low aw (0.65-0.90), low pH (pH=2.0-7.0), ethanol (0-15%), sorbic acid (0-1,500 ppm) and different temperatures (15°C-25°C) relevant for chocolate manufacturing. Z. rouxii was overall the most tolerant organism to the stress factors and grew within the same range of environmental conditions as found in chocolate pralines. It was able to grow at water activities down to 0.70, ethanol concentrations up to 6.0%, pH down to pH2.0, sorbic acid concentrations up to 1,500 ppm and at all temperatures tested. Eurotium amstelodami also showed high tolerance towards all the stress factors except for ethanol. None of the bacteria were able to grow at

    This study evaluates erosive potential of commonly used beverages, medicated syrup, and their effects on dental enamel with and without restoration in vitro. Test medias used in this study included carbonated beverage, noncarbonated beverage, high-energy sports drink medicated cough syrup, distilled water as the control. A total of 110 previously extracted human premolar teeth were selected for the study. Teeth were randomly divided into two groups. Test specimens were randomly distributed to five beverages groups and comprised 12 specimens per group. Surface roughness (profilometer) readings were performed at baseline and again, following immersion for 14 days (24 h/day). Microleakage was evaluated. The results obtained were analyzed for statistical significance using SPSS-PC package using the multiple factor ANOVA at a significance level of P syrup (P = 0.000), and distilled water (P = 0.000). High-energy sports drink showed highest surface roughness value and microleakage score among all test media and thus greater erosive potential to enamel while medicated syrup showed least surface roughness value and microleakage among all test media.

    The Brazilian breweries are following the technological changes that occur at the beer producer countries by gradually substituting the amylaceous adjuncts by the syrup ones. For this reason, this work was carried out to compare energetically two processes of brewing wort producing, using as study pattern a million liters of beer daily production brewery. The processes differ from the adjunct.The first utilized broken rice and the second utilized maltose syrup. both used as malt adjunct. Energetic evaluation was based on thermal energy and electric consumption of equipment used in wort production from silo sector to brew house. Upon using broken rice in the mashing the consumption of electric energy in silo sector during raw material transport was 75,064.40 Kcal (86.93 k W.h) and upon using maltose syrup was 52,288.00 Kcal (60.77 k W,h). Thus, reduction of electric energy of 30,34% corresponding to 22,776.40 Kcal (26.16 k W.) was obtained due to elimination of broken rice transport. Electric energy consumed at the brew house with broken rice was 166,809.96 Kcal (193.85 k W.h) and with the maltose syrup was 109,764.05 Kcal (127.57 k W.h). The difference between the two processes regarding electric energy, was 57.045.91 Kcal (66.28 k W.h) which is equivalent to 34,20% of reduction. Reduction was obtained through the elimination of broken rice boiling cereal and also through reduction in the time of use of motors of others equipment. Upon using broken rice thermal energy consumption at the brew house was 10,386,270.50 Kcal and 9,950,545.10 Kcal upon using maltose syrup. Reduction of thermal energy consumption was of 7,66% corresponding to 795, 725.40 Kcal due to elimination of the use of broken rice boiling cereal and reduction in the time of wort boiling. Reduction of total energy between two processes was of 8,24% corresponding to 875,547.76 Kcal. It was concluded that the process that uses maltose syrup requires less thermal and electric energy in comparison to the

    Upper respiratory tract infections (URTI), including acute bronchitis, are the frequent health problems and the most common reason for acute cough in adults. Even though the infections are caused mainly by viruses, and their course is usually not complicated, febrifuges, i.a. mucokinetics, or antitussives are used in the treatment of URTI in order to improve the quality of life and safety of patients. To evaluate the efficacy and safety of Bronchosol® herbal syrup in comparison to ambroxol preparations in the treatment of acute bronchitis in adult patients. The Bronchosol®/2013 study was a non-interventional, prospective, open-label, observational study. Data from adult patients treated with Bronchosol® syrup for acute bronchitis were collected and compared with data from patients treated for the same condition with ambroxol preparations. The severity of bronchitis symptoms was evaluated with the BSS (Bronchitis Severity Score) scale, and patients'quality of life wasassessed with the VAS (Visual Analogue Scale) scale. Between visits patients conducted self-observations and filled out observation diaries. Moreover, the data on adverse events were collected. In 87.68% of patients the infections were cured. Most of patients considered the studied drugs to be the agent decreasing the duration of infection and its intensity. The percentage of patients who declared that they had a less intense cough than during earlier infections was higher in the group of patients treated with Bronchosol® syrup in comparison to ambroxol treated patients (60.22% vs. 45.03%). 91.94% of patients treated with Bronchosol® considered this syrup to be very safe; in the ambroxol group such a declaration was made by 76.61% of patients. Bronchosol® syrup is an efficient, well-tolerated, and safe drug. Its efficacy in the treatment of acute bronchitis symptoms in adult patients is similar to the efficacy of ambroxol preparations.

    Rheum ribes L. is a plant native to China, Iran, Turkey, India, and a few other countries. Antidiarrheal activity is considered to be one of its important properties according to various systems of traditional medicine. An increasing rate of bacterial resistance to antibiotics has led to treatment failure in some cases of shigellosis in children, and underlines a need for safe, efficient and valid options. The purpose of this study is to evaluate the efficacy of R. ribes syrup as a complementary medicine for treatment of shigellosis in children. This randomized, double-blind, placebo-controlled trial started with a group of 150 children aged between 12-72 months with suspected Shigella dysentery. R. ribes syrup or placebo syrup was administered to the intervention and control groups, respectively for 5 days. In addition, the standard antibiotic treatment (ceftriaxone for the first 3 days and cefixime syrup for 2 further days) was administered to both groups. Body temperature, abdominal pain, need for antipyretics, defecation frequency, stool volume and consistency and microscopic stool examination were recorded as outcome measures. Any observed adverse effects were also recorded. Mean duration of fever and diarrhea in the R. ribes group was significantly lower than that in the placebo group (P = 0.016 and 0.001, respectively). In addition, patients in the R. ribes group showed shorter duration of need for antipyretics and shorter duration of abdominal pain (P = 0.012 and 0.001, respectively). However, there were no significant differences between the two groups regarding the microscopic stool analyses. Furthermore, no adverse effect was reported. R. ribes syrup can be recommended as a complementary treatment for children with Shigella dysentery. Iranian Registry of Clinical Trial: IRCT2014070518356N1.

    Here, a series of cellular-structured and predominantly mesoporous carbons were prepared via carbonization of glucose-fructose syrup (GFS) with sulfuric acid and subsequent calcination between 400∘C and 700∘C. Comparative results on the microstructure, chemical and textural properties of the newly produced carbons are presented. Furthermore, their adsorption performance for removal of acetaminophen from water was tested and it was found that the carbon calcined at 700∘C has a maximum adsorption capacity (98.7mgṡg-1) among all samples due to its suitable textural properties (BET surface area of 418m2ṡg-1 and total pore volume of 0.2cm3ṡg-1). This study demonstrates the potential use of GFS as a precursor in the preparation of carbonaceous materials for removal of biologically-active micropollutants from water.

    Acute exacerbations of chronic bronchitis (AECB) are defined as recurrent attacks of worsening bronchial inflammation that are marked by an increase in the volume of daily sputum produced, a change in color of the expectorated sputum, and worsening dyspnea. Farcosolvin (Pharco Pharmaceuticals, Alexandria, Egypt) is a mixture of ambroxol (15 mg); theophylline (50 mg); and guaiphenesin (30 mg), per 5 mL syrup. To test the clinical efficacy of Farcosolvin in the treatment of AECB in a randomized, single-blinded, controlled study design. One hundred patients with AECB were randomized to either Farcosolvin or guaiphenesin treatment groups, in addition to the standard medical treatment for their cases. Baseline clinical symptomatolgy of breathlessness, cough, and sputum severity scoring were compared before and after 3 and 7 days of treatment in both groups and the differences compared between groups. Changes in perceived improvement were also compared between groups using the Clinical Global Impression of Improvement or Change Scale (CGIC). There were statistically significant improvements in breathlessness and cough scores in both groups (pretreatment versus posttreatment at day 3 and at day 7; P < 0.05). There were highly statistically significant differences between groups in improvement in breathlessness and cough scores, after 3 and 7 days treatment, in favor of the Farcosolvin treatment group (P < 0.001). Out of 50 patients, 48 (96%) in the Farcosolvin-treated group rated their improvement on the CGIC scale as "much" and "very much" improved, while only 41 patients (82%) reported such a degree of improvement in the control group. The difference was statistically significant (P < 0.05). We concluded from our study that Farcosolvin syrup might be safe and effective in improving symptoms in cases of acute exacerbation of chronic bronchitis.

    A feasibility study of natural fruit jelly from three Algerian raw materials, namely date (Phoenix dactylifera l.) fruit syrup and suspension of orange albedo powder (OAP) in lemon juice (LJ) was performed by response surface methodology (RSM) based on central composite design (CCD). The textural properties of the final jelly were investigated through two dependent variables: hardness and stickiness. The cooking temperature (X1), corresponding to that of thermo stated oil bath, and cooking time (X 2), taken for heating the initial fruit mixture in the oil bath (from ambient temperature without fixing however, the final temperature), were found to be the most influent factors, compared to °Brix of date syrup (X3) and temperature (X4) of the cooling stage following the cooking process. Results have also shown that the second-degree polynomial models correctly fit experimental data (R(2), adjusted R(2) (R(2) adj) and cross-validation (Q(2)) ≈ 1). Considering textural properties of commercial jellies as a reference, it was found that the cooking temperature of 155 °C for 10 min gave a jelly with suitable textural properties. On the other hand, FT-IR spectra revealed that the structure of such jelly was partially close to that of pectin molecules. Finally, the color analysis in the CIELab system of the fruit mixture over the cooking process showed that both lightness (L(*)) and a*/b* ratio were not affected by the experienced temperature range (80-155 °C).

    Acute cough represents the most common illness evaluated in the outpatient settings. Available remedies for its management are generally allopathic combinations of antihistamines and decongestants that achieve antitussive activity, but often with unpleasant side effects prompting the need to explore safer and effective options. Honitus is an Ayurvedic proprietary herbal cough syrup with benefits of honey, intended to provide relief in acute nonproductive cough and throat irritation without causing drowsiness. This study investigated the safety and efficacy of Honitus in reducing acute nonproductive cough and throat irritation in comparison to a standard marketed allopathic cough syrup intended for use in similar conditions. This was a randomized double-blind study conducted in 105 individuals who received orally 2 tsp (10 ml) of either Honitus or marketed cough syrup (MCS) four times a day for 3 days. Response to treatment was evaluated from baseline to the end of treatment period on the basis of changes in day and night frequencies of cough, throat irritation and development of adverse events (AEs). Honitus was found safe and effective in reducing symptoms of acute nonproductive cough, throat irritation, and comparable to MCS in reducing day and night frequencies of cough, the time to relief from cough and throat irritation and the Physician's Global Assessment of cough. Honitus showed comparably better results than MCS on throat irritation, the duration of relief from cough and throat irritation without causing drowsiness. No AEs related to study or study products were reported. Honitus Syrup is safe and effective in reducing the symptoms of acute nonproductive cough and throat irritation without causing drowsiness.

    The efficacy of midazolam as premedication in children for providing pre-operative sedation and reducing parental separation anxiety has been well established. Many studies have compared the effectiveness and medication acceptance of midazolam via oral and intranasal routes. In this study, we have compared the ease of administration of oral midazolam syrup and intranasal midazolam spray as premedication, administered by parents to children. Ninety children were randomly allocated into one of the two groups: group N received nasal midazolam spray 0.2 mg/kg and group O received oral midazolam syrup 0.5 mg/kg administered by the parent. The parent recorded ease of administration score and facial hedonic score. The observer recorded modified medication acceptance score. Vitals and sedation scores were assessed at specific intervals. Thirty minutes after drug administration the child was separated from the parent, and parental separation anxiety score was recorded. Mask acceptance score was recorded after application of mask upon arrival in the OT. Oral midazolam syrup was found to have better ease of administration than intranasal midazolam spray as felt by the parent. Medication acceptance was better for oral midazolam. Both the groups had similar sedation scores at 15 and 30 min. Children in the oral group had a better reduction in parental separation anxiety at 30 min after drug administration and better mask acceptance than the nasal group. Oral midazolam syrup is easier for parents to administer and has better medication acceptance in children when compared to intranasal midazolam spray.

    The agonist-receptor-transducer model of D. Ennis is applied to beverage formulations sweetened with high fructose corn syrup, sucralose, and other high-potency sweeteners, confirming the utility of the model, and supports the growing volume of evidence for multiple binding sites on the sweetness receptor. The model is further simplified to require less parameters for other sweetener blend systems whenever potency information is available for the single sweeteners.

    Sena-Graph syrup has recently been formulated by an Iranian pharmaceutical company for being used in bowel evacuation before radiography, colonoscopy and surgery. This study compares the efficacy, adverse effects and patient compliance of two bowel preparation regimens with castor oil and Sena-Graph syrup in of outpatients for Intravenous Urography (IVU). One hundred and fourteen consecutive outpatients were randomized to receive either the standard bowel preparation with 60 mL of castor oil or the test method with 60 mL of Sena-Graph syrup before IVU examination. Demographic data of patients and their prior bowel preparation experience were collected before the examination. Two radiologists, blinded to the method of bowel preparation, reviewed the radiographs and graded the bowel preparation. The compliance and acceptability of both regimens were assessed by using structured questionnaires filled by the patients. The Numbers, ages, weights and gender distribution of patients and their prior bowel preparation experience in the two groups did not differ significantly. The cleanliness scores for the castor oil and Sena-Graph group were 3.97 ± 0.971 and 4.87 ± 0.917, respectively. The results indicated that Sena-Graph syrup causes a better bowel cleansing compared castor oil. Adverse effects in Sena-Graph groups were significantly lower than the castor oil group. Acceptability of the regimen in patients who used Sena-Graph was higher than the other group. The Sena-Graph regimen is significantly more effective and better tolerated than of Castor oil regimen in bowel cleansing. The incidence and severity of the adverse effects from Castor oil was higher than Sena-Graph.

    A new rapid method was developed and optimized for routine multi-element determination of traces of metals in antitussive syrups using direct introduction of diluted syrup into the nebulization system of inductively coupled plasma atomic emission spectrometer (ICP-AES). Using a Scott-type double-pass spray chamber combined with a cross-flow nebulizer, the optimum ICP conditions, like RF incident power, argon gas flow rate and nebulizer sample uptake flow rate were found. A critical objective of the study was to evaluate the matrix effect on the intensity and consequently on the sensitivity of the developed method. Thus, the maximum syrup concentration which could be introduced into the argon plasma, was estimated. The sensitivity variation was calculated as compared to the corresponding sensitivity obtained from aqueous solutions for each analyte. The performance characteristics of the proposed method were evaluated for quantitative and semi-quantitative determination and finally, the method was applied to the analysis of various commercial antitussives.

    Full Text Available Introduction: Arachidonic acid is an important essential fatty acid in human nutrition. The filamentous fungus Mortierella alpina has been identified as a promising producer of arachidonic acid. Mortierella alpine can accumulate up to 40% (w/w lipid, of which up to 40% can be arachidonic acid. Materials and methods: Mortierella alpina CBS 754.68 was cultivated in low cost substrate such as glucose syrup, brown sugar and starch for lipid and arachidonic acid production. The reduced sugar, total lipids and content of ARA were determined by dinitrosalicylic acid method, soxhlet and Gas chromatography–mass spectrometry (GC-MS respectively. Results: The carbon sources were applied at 70 g/l and nitrogen source (soybean powder at 10 g/lit. The results showed that lipid in dry biomass in glucose syrup, starch and brown sugar media were obtained 32, 25 and 13 % w/w respectively. The arachidonic acid contents of lipid in the glucose syrup, starch and brown sugar media were 41, 33 and 31 % w/w respectively. Discussion and conclusion: Lipid fatty acid compositions are affected by the growth of microorganism. Cell membrane fatty acids such as stearic acid and oleic acid increased substantially concomitant with increases in the amount of biomass. Biomass and oil production efficiency fell due to inappropriate brown sugar medium.

    Over-the-counter (OTC) anti-cough preparations, many of which contain codeine (an opioid) or dextromethorphan (an opioid-like), are widely available in Taiwan and thus susceptible to overuse or abuse. We aimed to investigate whether opioids in the form of OTC antitussives play a significant role in medication abuse in Taiwan. Data on the consumption of codeine and dextromethorphan in antitussives and expectorants from 2011 through 2014 in Taiwan were provided by IMS Health (Intercontinental Marketing Services). These data were then analyzed for trends and variance according to availability, as prescription or OTC, and according to drug type, as codeine or dextromethorphan, in order to form four primary sectors under opioid-containing anti-cough syrup consumption. From 2011 to 2014, use of opioid-containing cough syrup fluctuated between 6% and 9% from year to year for all cough syrup consumption, with an overall declining trend (11.3% per year relative to 2011). Within the underlying sectors, mean consumption for prescription dextromethorphan (61.4%) outstripped the other three sectors, followed in decreasing order by OTC codeine (20.2%), OTC dextromethorphan (10.5%), and prescription codeine (8.0%). However, movement in consumption corresponded mainly with OTC codeine, whose variance greatly exceeded that of the other sectors, which follow in order of decreasing variance as OTC dextromethorphan, prescription dextromethorphan, and prescription codeine. The fairly low and stable consumption of prescription codeine suggested that physicians in Taiwan were careful in prescribing codeine, and that the medical demand for codeine was stable. The large variance in OTC codeine consumption suggested that a minority of consumers purchased significant quantities of codeine for non-medical purposes. Although opioids in cough syrup were not a large part of overall consumption and thus not widely abused, the data revealed that OTC codeine-containing cough syrup may serve as an

    Intermittent maple syrup urine disease (MSUD) is a potentially life-threatening metabolic disorder caused by a deficiency of branched chain α-ketoacid dehydrogenase (BCKD) complex. In contrast to classic MSUD, children with the intermittent form usually have an atypical clinical manifestation. Here, we describe the presenting symptoms and clinical course of a Chinese boy with intermittent MSUD. Mutation analysis identified two previously unreported mutations in exon 7 of the BCKDHB gene: c.767A > G (p.Y256C) and c.768C > G (p.Y256X); the parents were each heterozygous for one of these mutations. In silico analysis predicted Y256C probably affects protein structure; Y256X leads to a premature stop codon. This case demonstrates intermittent MSUD should be suspected in cases with symptoms of recurrent encephalopathy, especially ataxia or marked drowsiness, which usually present after the neonatal period and in conjunction with infection. symmetrical basal ganglia damage but normal myelination in the posterior limb will assist differential diagnosis; alloisoleucine is a useful diagnostic marker and mutation analysis may be of prognostic value. These novel mutations Y256C and Y256X result in the clinical manifestation of a variant form of MSUD, expanding the mutation spectrum of this disease.

    Maple syrup urine disease (MSUD) is a rare hereditary metabolic condition where the body is unable to breakdown amino acids causing toxic buildup. Acute and long-term management of MSUD involves a restricted diet and regular monitoring of amino acid levels; however, more recently liver transplants have been shown to be successful in treating this condition. Even with successful management of MSUD there is evidence from pediatric cases that shows a distinct pattern of neurocognitive deficits associated with this condition, including impaired nonverbal skills and psychomotor functioning with relatively intact verbal abilities. In the present paper, we report an adult case of MSUD with associated neurocognitive deficits and functional limitations following liver transplantation. Neuroimaging revealed no structural abnormalities, while the results from the neuropsychological evaluation showed impairment in visual-spatial processing, attention, executive functioning, and psychomotor abilities, with relative strengths in verbal skills. The patient also showed reduced adaptive functioning and mild anxiety. This case demonstrates neurocognitive deficiencies within the context of normal magnetic resonance imaging. The possible underlying mechanism of this neuropsychological profile is discussed in relation to other neurodevelopmental models.

    In the United States, high-fructose corn syrup (HFCS) has become a sucrose replacement for honey bees and has widespread use as a sweetener in many processed foods and beverages for human consumption. It is utilized by commercial beekeepers as a food for honey bees for several reasons: to promote brood production, after bees have been moved for commercial pollination, and when field-gathered nectar sources are scarce. Hydroxymethylfurfural (HMF) is a heat-formed contaminant and is the most noted toxin to honey bees. Currently, there are no rapid field tests that would alert beekeepers of dangerous levels of HMF in HFCS or honey. In this study, the initial levels and the rates of formation of HMF at four temperatures were evaluated in U.S.-available HFCS samples. Different HFCS brands were analyzed and compared for acidity and metal ions by inductively coupled plasma mass spectroscopy. Levels of HMF in eight HFCS products were evaluated over 35 days, and the data were fit to polynomial and exponential equations, with excellent correlations. The data can be used by beekeepers to predict HMF formation on storage. Caged bee studies were conducted to evaluate the HMF dose-response effect on bee mortality. Finally, commercial bases such as lime, potash, and caustic soda were added to neutralize hydronium ion in HMF samples, and the rates of HMF formation were compared at 45 degrees C.

    The high viscosity and stickiness of honey in its natural state causes handling difficulties, therefore the demand for honey powder is continuously increasing. Powder preparation has to be performed gently because of the thermo- and oxidation- sensitive nature of honey. The aim of this study was to determine the degradation of invertase during drying as an indirect measure of the retention of valuable honey nutrients. The reaction kinetics were estimated in polyfloral honey and honey-glucose syrup (GS) formulation and the impact of temperature (40-70°C) and water activity (a w 0.23-0.81) was established. The honey-GS formulation (55:45 w/w) was intended for the preparation of high-grade honey powders using the vacuum-drying method. Invertase inactivation at temperatures below 60°C followed first-order kinetics. At 60°C high dilution (a w 0.81) and at 70°C, heterogeneous inactivation behaviour was observed. The best fit of invertase heterogeneous inactivation kinetic was achieved with the Cerf two-fraction model. The GS addition showed a stabilizing effect on invertase during thermal degradation. The data on invertase inactivation gathered here can be utilized to select optimal parameters for honey vacuum-drying and other thermal processes in order to achieve maximum invertase retention. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Liquid and syrupy dietary saps and juices of plant origin, characterized by the presence of large quantities of saccharides (glucose, fructose, or sucrose) and containing amino acids, were analyzed for the presence of D-amino acids using enantioselective gas chromatography-mass spectrometry. D-amino acids were detected in processed saps and juices of trees (maple, palm, birch), fruits (grape, apple, pear, pomegranate, date), and various other plants (agave, beetroot, sugar cane, carob). D-Ala was detected in all plant products and amounted to approximately 34% D-Ala (relative to L-Ala + D-Ala) in Canadian maple syrups, to approximately 13% in palm saps, and to 48 and 13% D-Ala, respectively, in concentrated grape juices (Spanish Arrope and Turkish Pekmez). Varying amounts and kinds of other D-amino acids were also detected. To test the hypothesis that racemization, that is, partial conversion of L-amino acids into their corresponding D-enantiomers, occurs at reversible stages of the Maillard reaction, the Amadori compound fructose-L-phenylalanine was synthesized. On heating at 200 degrees C for 5 (20) min, release of 10.8% (24.2%) D-Phe was detected. From the data it is concluded that the Amadori compounds formed in the course of the Maillard reaction are pecursors of D-amino acids in foodstuffs.

    A prospective, double-blind study compared the effectiveness of sucralfate suspension with diphenhydramine syrup plus kaolin-pectin in reducing severity and pain of radiation-induced oropharyngeal mucositis. Fourteen patients who received at least 4600 cGy to the oral cavity used one of the mouth rinses four times a day, beginning at 1600 cGy. Data were collected on daily perceived pain and helpfulness of mouth rinse, weekly mucositis grade, weight change, and interruption of therapy. Analysis of data revealed no statistically significant differences between the two groups in any parameter. A retrospective review of 15 patients who had received at least 4600 cGy radiation to the oropharynx but had not used a daily mouth-coating rinse, was compared with the study group. Comparison of the two groups suggested that consistent daily oral hygiene and use of a mouth-coating agent will result in less pain and may reduce weight loss and interruption of radiation because of severe mucositis

    For decades guaco species have been empirically used for the treatment of respiratory diseases. However, studies have shown that the toxic and therapeutic effects of the main guaco metabolites are dose-dependent, and none clinical study was done to evaluate the behavior of these substances in humans. In this work, a pilot study measuring the kinetic profile of the main guaco metabolites was performed leading to the knowledge of an alternative route of coumarin metabolism in humans. Initial screenings demonstrated that the administration of 60 mL of guaco syrup (single dose) did not provide sufficient levels of coumarin (COU), 7-hydroxycoumarin (7-HCOU), o-coumaric acid (OCA) and kaurenoic acid (KAU). The pharmacokinetic parameters were calculated by orally administering 60 mL of guaco syrup spiked with 1500 mg of COU. The kinetic study demonstrated that the plasmatic levels of 7-HCOU (considered the main metabolite of COU) were 10 times lower than the levels of COU, and the kinetic profile of 7-HCOU suggests sequential metabolism in the liver with low access of 7-HCOU to the systemic circulation. The study also demonstrated that OCA is one of the main bioavailable metabolites of COU. Therefore, the hydrolysis of the lactone ring forming a carboxylated compound is one of the possible routes of COU metabolism in humans. The half-lives of COU, 7-HCOU and OCA were approximately 4.0, 1.0 and 3.0 h, respectively and there was evidence that the recommended dosage of guaco syrup did not provide sufficient levels of COU, 7-HCOU or OCA to obtain a bronchodilation effect. Clinical studies are necessary to prove the efficacy and safety of products based on guaco. PMID:25757073

    Maple syrup urine disease (MSUD) is caused by mutations in genes BCKDHA, BCKDHB, DBT encoding E1α, E1β, and E2 subunits of enzyme complex, branched-chain alpha-ketoacid dehydrogenase (BCKDH). BCKDH participates in catabolism of branched-chain amino acids (BCAAs) - leucine, isoleucine and valine in the energy production pathway. Deficiency or defect in the enzyme complex causes accumulation of BCAAs and keto-acids leading to toxicity. Twenty-four patients with MSUD were enrolled in the study for molecular characterization and genotype-phenotype correlation. Molecular studies were carried out by sequencing of the 3 genes by Sanger method. Bioinformatics tools were employed to classify novel variations into pathogenic or benign. The predicted effects of novel changes on protein structure were elucidated by 3D modeling. Mutations were detected in 22 of 24 patients (11, 7 and 4 in BCKDHB, BCKDHA and DBT genes, respectively). Twenty mutations including 11 novel mutations were identified. Protein modeling in novel mutations showed alteration of structure and function of these subunits. Mutations, c.1065 delT (BCKDHB gene) and c.939G > C (DBT gene) were noted to be recurrent, identified in 6 of 22 alleles and 5 of 8 alleles, respectively. Two-third patients were of neonatal classical phenotype (16 of 24). BCKDHB gene mutations were present in 10 of these 16 patients. Prenatal diagnoses were performed in 4 families. Consanguinity was noted in 37.5% families. Although no obvious genotype-phenotype correlation could be found in our study, most cases with mutation in BCKDHB gene presented in neonatal period. Large number of novel mutations underlines the heterogeneity and distinctness of gene pool from India. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Soybean carbohydrate is often found to limit the use of protein in soy flour as food and animal feed due to its indigestibility to monogastric animal. In the current study, an enzymatic process was developed to produce not only soy protein concentrate and soy protein isolate without indigestible carbohydrate but also soluble reducing sugar as potential fermentation feedstock. For increasing protein content in the product and maximizing protein recovery, the process was optimized to include the following steps: hydrolysis of soy flour using an Aspergillus niger enzyme system; separation of the solid and liquid by centrifugation (10 min at 7500×g); an optional step of washing to remove entrapped hydrolysate from the protein-rich wet solid stream by ethanol (at an ethanol-to-wet-solid ratio (v/w) of 10, resulting in a liquid phase of approximately 60 % ethanol); and a final precipitation of residual protein from the sugar-rich liquid stream by heat treatment (30 min at 95 °C). Starting from 100 g soy flour, this process would produce approximately 54 g soy protein concentrate with 70 % protein (or, including the optional solid wash, 43 g with 80 % protein), 9 g soy protein isolate with 89 % protein, and 280 ml syrup of 60 g/l reducing sugar. The amino acid composition of the soy protein concentrate produced was comparable to that of the starting soy flour. Enzymes produced by three fungal species, A. niger, Trichoderma reesei, and Aspergillus aculeatus, were also evaluated for effectiveness to use in this process.

    The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Thirty-six individually housed Holstein male calves were blocked according to weight and date of birth and assigned to one of the starter feed treatments, during an 8 week study: i) starter containing 65% corn with no MO or GS (0MO); ii) starter containing 60% corn and 5% MO (5MO); iii) starter containing 55% corn and 10% MO (10MO); and iv) starter containing 60% corn and 5% GS (5GS). Animals received 4 L of milk replacer daily (20 crude protein, 16 ether extract, 12.5% solids), divided in two meals (0700 and 1700 h). Starter and water were provided ad libitum. Starter intake and fecal score were monitored daily until animals were eight weeks old. Body weight and measurements (withers height, hip width and heart girth) were measured weekly before the morning feeding. From the second week of age, blood samples were collected weekly, 2 h after the morning feeding, for glucose, β-hydroxybutyrate and lactate determination. Ruminal fluid was collected at 4, 6, and 8 weeks of age using an oro-ruminal probe and a suction pump for determination of pH and short-chain fatty acids (SCFA). At the end of the eighth week, animals were harvested to evaluate development of the proximal digestive tract. The composition of the starter did not affect (p>0.05) concentrate intake, weight gain, fecal score, blood parameters, and rumen development. However, treatment 5MO showed higher (p0.05). Thus, it can be concluded that the replacement of corn by 5% or 10% sugar cane molasses or 5% GS on starter concentrate did not impact performance, however it has some positive effects on rumen fermentation which may be beneficial for calves with a developing rumen.

    It is unclear whether energy-containing drinks, especially those sweetened with high-fructose corn syrup (HFCS), promote positive energy balance and thereby play a role in the development of obesity. The objective was to examine the satiating effects of HFCS and sucrose in comparison with milk and a diet drink. The effects of four 800-mL drinks [corrected] containing no energy or 1.5 MJ from sucrose, HFCS, or milk on satiety were assessed, first in 15 men and 15 women with a mean (+/-SD) body mass index (BMI; in kg/m(2)) of 22.1 +/- 1.9 according to visual analogue scales (VAS) and blood variables and second in 20 men and 20 women (BMI: 22.4 +/- 2.1) according to ingestion of a standardized ad libitum meal (granola cereal + yogurt, 10.1 kJ/g). Fifty minutes after consumption of the 1.5-MJ preload drinks containing sucrose, HFCS, or milk, 170%-mm VAS changes in satiety were observed. Glucagon-like peptide 1 (GLP-1) (P < 0.001) and ghrelin (P < 0.05) concentrations changed accordingly. Compensatory energy intake did not differ significantly between the 3 preloads and ranged from 30% to 45%. Energy intake compensations were related to satiety (r = 0.35, P < 0.05). No differences were observed between the effects of the sucrose- and HFCS-containing drinks on changes in VAS and on insulin, glucose, GLP-1, and ghrelin concentrations. Changes in appetite VAS ratings were a function of changes in GLP-1, ghrelin, insulin, and glucose concentrations. Energy balance consequences of HFCS-sweetened soft drinks are not different from those of other isoenergetic drinks, eg, a sucrose-drink or milk.

    Full Text Available A 7-year-old boy, weighing 18 kg, was diagnosed with maple syrup urine disease (MSUD. He suffered from spasticity of the lower limbs and pain that did not respond to oral medications. Injections of botulinum toxin A (BTX-A at 10 sites and epidural analgesia with 0.125% bupivacaine were used to treat spasticity with good results. We conclude that BTX-A combined with epidural analgesia may be a useful treatment option for incapacitating, painful spasticity related to MSUD. This treatment modality allowed a comprehensive rehabilitation program to be completed and it lasted longer than 9 months.

    Given the characteristic age-prevalence curve of Schistosoma infection, preventive chemotherapy with praziquantel is primarily targeted at school-aged children, whilst, in highly endemic areas, other high-risk groups might be included for regular treatment. Nevertheless, schistosomiasis can affect children well before they reach school-age, but this population group is usually excluded from preventive chemotherapy. We assessed the safety and efficacy of praziquantel syrup (Epiquantel®) in preschool-aged children in three villages of Niger. Children aged ≤72 months provided multiple urine and stool samples that were microscopically examined using standard protocols. Schistosoma-positive children were treated with praziquantel syrup at a dose of 40 mg/kg after a meal of millet porridge. Children remained under medical supervision for 4h and adverse events were recorded. Additionally, a questionnaire was administrated to the mothers/guardians 24h post-treatment for further probing of adverse events. Treatment efficacy was evaluated 3 and 6 weeks post-treatment using multiple stool and urine samples. A third of the 243 treated children reported adverse events within 4h, whilst a further 6.2% reported adverse events upon probing 24h post-treatment. Abdominal pain, bloody diarrhoea and sleepiness were the most common adverse events, but these were transient and self-limiting. Praziquantel syrup showed moderate-to-high efficacy against Schistosoma haematobium with egg reduction rates of 69.4% and 71.2% 3 and 6 weeks post-treatment and cure rates of 85.7% (95% confidence interval (CI) 79.7-90.5%) and 94.9% (95% CI 90.5-97.6%), respectively. Considerably lower cure and egg reduction rates were observed against Schistosoma mansoni (e.g. cure rate at 6-week post-treatment follow-up was only 50.6% (95% CI 39.9-61.2%). Concluding, praziquantel syrup is well tolerated in preschool-aged children with moderate-to-high efficacy against S. haematobium, but considerably lower

    Glucose isomerase (GI) is used in vitro to convert d-glucose to d-fructose, which is capable of commercial producing high fructose corn syrup (HFCS). To manufacture HFCS at elevated temperature and reduce the cost of enriching syrups, novel refractory GIs from Thermoanaerobacterium xylanolyticum (TxGI), Thermus oshimai (ToGI), Geobacillus thermocatenulatus (GtGI) and Thermoanaerobacter siderophilus (TsGI) were screened via genome mining approach. The enzymatic characteristics research showed that ToGI had higher catalytic efficiency and superior thermostability toward d-glucose among the screened GIs. Its optimum temperature reached 95°C and could retain more than 80% of initial activity in the presence of 20mM Mn 2+ at 85°C for 48h. The K m and k cat /K m values for ToGI were 81.46mM and 21.77min -1 mM -1 , respectively. Furthermore, the maximum conversion yield of 400g/L d-glucose to d-fructose at 85°C was 52.16%. Considering its excellent high thermostability and ameliorable application performance, ToGI might be promising for realization of future industrial production of HFCS at elevated temperature.

    Full Text Available A new method for determination of salbutamol sulfate has been developed using poly(4-amino-3-hydroxynaphthalene sulfonic acid/GCE. Cyclic voltammetric investigation of the electrochemical behavior of salbutamol sulfate at the polymer modified glassy carbon unveiled electrocatalytic activity of the modifier towards irreversible oxidation of salbutamol sulfate. Dependence of peak current predominantly on scan rate than on square root of scan rate, and peak potential shift with pH demonstrated that oxidation of salbutamol sulfate at the polymer modified electrode follows adsorption reaction kinetics with proton participation.Under optimized solution and differential pulse voltammetric parameters, the oxidative peak current showed linear dependence on salbutamol sulfate concentration in the range 0.2 to 8 μM with method detection limit (3s/m and determination coefficient (R2 of 6.8 × 10−8 M and 0.99786, respectively. Low method detection limit, relatively wide linear range, and recovery results of spiked standard salbutamol sulfate in syrup samples in the range 96.7–98.9% validated the method for determination of salbutamol sulfate in pharmaceutical formulations.Differential pulse voltammetric analysis of salbutamol sulfate syrup formulation for its salbutamol sulfate content revealed 98.8 to 99.3% of the labeled value confirming the applicability of the developed method for determination of salbutamol sulfate in real samples.

    Full Text Available Abstract Background The replacement of sucrose with HFCS in food products has been suggested as playing a role in the development of obesity as a public health issue. The objective of this study was to examine the effects of four equally hypocaloric diets containing different levels of sucrose or high fructose corn syrup (HFCS. Methods This was a randomized, prospective, double blind trial, with overweight/obese participants measured for body composition and blood chemistry before and after the completion of 12 weeks following a hypocaloric diet. The average caloric deficit achieved on the hypocaloric diets was 309 kcal. Results Reductions were observed in all measures of adiposity including body mass, BMI,% body fat, waist circumference and fat mass for all four hypocaloric groups, as well as reductions in the exercise only group for body mass, BMI and waist circumference. Conclusions Similar decreases in weight and indices of adiposity are observed when overweight or obese individuals are fed hypocaloric diets containing levels of sucrose or high fructose corn syrup typically consumed by adults in the United States.

    The unique characteristics and healthful reputation of caffeine-free rooibos tea (RT) make it an ideal carrier for vitamin D 3 supplementation, and a potential base for the addition of Saskatoon berry syrup (SBS), a natural flavor additive. The objective of this study was to determine the effect of vitamin D 3 fortification and SBS addition on the flavor profile, consumer acceptability, and antioxidant properties of RT. Six formulations (RT, RT with SBS, RT with SBS and vitamin D 3 , RT with vitamin D 3 , green tea [GT], and GT with SBS) were evaluated by 12 trained panelists and 114 consumers. The formulations were also assessed for antioxidant capacity, physical characteristics, and untargeted phytochemical content. Sensory results revealed that the mean intensity values for berry and sweet attributes were significantly higher (P syrup. Acceptability of flavor, aftertaste, and overall acceptability were also significantly higher for the RT with SBS. The addition of SBS to RT significantly increased the antioxidant capacities which may increase the related health benefits of RT. SBS contributed several polyphenols, particularly flavonoids, to the tea. Vitamin D 3 added to RT formulations did not significantly affect the sensory attributes, acceptability, or antioxidant content. For the development of a functional vitamin D 3 fortified iced-tea beverage that can be consumed as part of the daily diet, SBS could be a favorable flavoring additive that may provide additional health benefits. © 2017 Institute of Food Technologists®.

    Critics of free trade agreements have argued that they threaten public health, as they eliminate barriers to trade in potentially harmful products, such as sugar. Here we analyze the North American Free Trade Agreement (NAFTA), testing the hypothesis that lowering tariffs on food and beverage syrups that contain high-fructose corn syrup (HFCS) increased its use in foods consumed in Canada. We used supply data from the Food and Agriculture Organization of the United Nations to assess changes in supply of caloric sweeteners including HFCS after NAFTA. We estimate the impact of NAFTA on supply of HFCS in Canada using an innovative, quasi-experimental methodology - synthetic control methods - that creates a control group with which to compare Canada's outcomes. Additional robustness tests were performed for sample, control groups and model specification. Tariff reductions in NAFTA coincided with a 41.6 (95% confidence interval 25.1 to 58.2) kilocalorie per capita daily increase in the supply of caloric sweeteners including HFCS. This change was not observed in the control groups, including Australia and the United Kingdom, as well as a composite control of 16 countries. Results were robust to placebo tests and additional sensitivity analyses. NAFTA was strongly associated with a marked rise in HFCS supply and likely consumption in Canada. Our study provides evidence that even a seemingly modest change to product tariffs in free trade agreements can substantially alter population-wide dietary behaviour and exposure to risk factors. © 2017 Canadian Medical Association or its licensors.

    Aluminium has been proposed as an environmental factor that may affect several enzymes and other biomolecules related to neurotoxicity and Alzheimer's disease (AD). The promising protective effect of aqueous saffron extract and honey syrup on neurotoxicity induced by aluminuim chloride (AlCl(3)) may be derived from their own antioxidant properties. Balb/c and C57BL/6 mice (35-40 g) were injected with AlCl(3), 40 mg/kg/day for 45 days. Each mice strain was divided into four groups: AlCl(3) treated group, AlCl(3) plus water saffron extract group (administered with saffron extract at 200 mg/kg b.w. once a day for the experimental period), AlCl(3) plus honey syrup group (administered with honey syrup at 500 mg/kg b.w. for 45 days). The control group received no treatment. Oxidative stress and antioxidant status were estimated in the brain and differential display was performed for both mice strains to scan the mRNA in the treated and non treated groups. In addition, the up and down regulated genes were isolated, cloned and sequenced. The sequence analysis was performed and compared with the other genes cited on GenBank. The results show that there was a decrease in the activity of the antioxidant enzymes (P≤0.001) such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) in the AlCl3 groups of both mice strains. The level of brain thiobarbituric acid reactive substances (TBARS) showed a significant increase (P≤0.001) of lipid peroxidation (LPO) in the AlCl(3) groups. There was an indication of carcinogenicity in the AlCl(3) treated group representing an increase in serum tumor markers such as arginase and a-l-fucosidase. More than 350 band patterns were obtained and about 22 different up-down regulated genes were observed. The sequence analysis of the three selected up-regulated genes revealed that they are similar to B-cell lymphoma 2 (Bcl-2), R-spondin and the inositol polyphosphate 4-phosphatase genes (INPP4B), respectively.

    To compare the flavour and taste preferences of two acid-inhibitory therapies in children. 104 (52 male and 52 female) healthy children aged 6-11 years participated in this phase IV single-centre, taste-test study after parental consent was obtained. Children were divided into two groups based upon age: group 1 included children aged 6-8 years and group 2 included children aged 9-11 years. Within each group an equal number of male and female subjects were recruited. Within each of the four strata defined by group and sex, an equal number of subjects were randomised to taste the strawberry-flavoured lansoprazole 15mg orally disintegrating tablet or the ranitidine 75mg/5mL peppermint-flavoured syrup samples in position 1. In group 1, the lansoprazole 15mg delayed-release orally disintegrating tablet was dispersed in 5mL of water, while in group 2, children gently rolled the tablet on the tongue until dissolution, before swallowing the particles. Children given the dose of lansoprazole dispersed in water (group 1) and the ranitidine dose (groups 1 and 2) were to taste it, swish it in their mouth for up to 10 seconds, and then swallow it. Children were given ambient temperature water and unsalted crackers to cleanse the palate during a 10-minute break between tastings. After each tasting, children rated their degree of liking on a five-point facial hedonic scale (5 = like very much, 1 = dislike very much). Product preference was recorded after the tasting of both samples. Among group 1 and group 2 participants, 86.5% (45/52) and 90.4% (47/52) of children, respectively, 'liked' ('like a little' or 'like very much') the strawberry-flavoured lansoprazole orally disintegrating tablet. The proportion of children who 'liked' the peppermint-flavoured ranitidine syrup was lower than the proportion who liked lansoprazole, and the proportions were similar between the groups: 13.5% (7/52) in group 1 and 9.6% (5/52) in group 2. Children in both groups preferred the strawberry

    A stability-indicating method for the determination of S-carboxymethyl-L-cysteine and related degradation impurities in Exputex® 250mg/5mL syrup was developed in anion-exchange liquid chromatography mode. A forced degradation study supported the method development to ensure stability indicating conditions. Aqueous solutions of the active pharmaceutical ingredient and syrup samples at different pH-values were stress-tested in different thermal, light exposure and headspace conditions. One degradation product was detected in thermal stress studies at 60°C and 80°C in the pH range 5.0-7.0 and was identified by mass spectrometry as 5-oxo-thiomorpholine-3-carboxylic acid (lactam of carbocysteine). A second degradation product was only generated in moderately strong oxidizing conditions (0.5% H2O2 aqueous solution) and was identified as S-carboxymethyl-L-cysteine-(R/S)-sulphoxide (carbocysteine sulphoxide). The method was developed on a Zorbax SAX column, in isocratic mode. The mobile phase consisted of 200mM phosphate solution at pH 4.0 and acetonitrile (50:50 v/v) and UV detection was performed at a wavelength of 205nm. The method was linear for carbocysteine (R>0.9982) over a concentration range of 2.5-50μg/mL and 0.4-0.6mg/mL. Linearity for the impurities was shown from the LOQ to 50μg/mL. Specificity was verified and accuracy demonstrated for the active ingredient and its degradation products in syrup samples at 3 levels around their respective specification limits. Repeatability, intermediate precision and inter-laboratory reproducibility were assessed on three commercial batches, analyzed in triplicate by two operators at both the transferring and the receiving site and demonstrated a successful method transfer to the manufacturing quality control laboratory.

Though winter may just be getting started in some areas, it's always fun to appreciate the good things about winter, including the special time at the end of winter in New England known as "sugaring time." The sap starts flowing in the sugar maples, and…

    Color additives are used in pediatric syrup formulations as an excipient; though not pre-requisite, but pediatric syrup formulations are normally colored. An attempt has been made to measure simultaneously the single drug, acetaminophen (AT), along with the colors, carmoisine (CA), erythrosine (ET), and sunset yellow FCF (SSY) added in it by three derivative spectroscopy methods namely, 1st order, ratio, and differential derivative methods. Moreover, evaluation has been made for the exposure assessment of the colors added as excipient because some colors have been reported to cause allergic reactions and hypersensitivity in children. The present methods provide simple, accurate, and reproducible quantitative determination of the drug, AT, along with the color in synthetic mixtures and commercial drug formulations without any interference. The limit of detection varied from 0.0001-0.31 μg/ml while limit of quantification ranged from 0.002-1.04 μg/ml in all the three methods. The calibration curve of all the three derivative methods exhibited good linear relationship with excellent regression coefficients (0.9986-1.000). Both intra-day and inter-day precisions showed %RSD value less than 2% while the percentage recovery was found between 96.8-103.8%. The sensitivity of the proposed methods is almost comparable to HPLC and thus, can be used for determination of drug AT, and color simultaneously in pharmaceutical formulation on routine basis. The present methods also showed that colors like SSY and ET are saturating more than 50% of acceptable daily intake (ADI) value which is alarming and needs to be considered for modification by regulatory authorities to safeguard the health of children.

    Full Text Available High fructose corn syrup (HFCS is commonly found in soft drinks and juice beverages, as well as in many pre-packaged foods such as breakfast cereals, baked goods and dairy desserts. Historically, sucrose (table sugar was primarily added to processed foods and beverages as the sweetening agent. In recent years, the use of HFCS has significantly increased in popularity due to its sweetness, ability to enhance flavor and shelf life, and its low cost. HFCF made by enzymatic isomerization of glucose to fructose was introduced as HFCS-42 (42% fructose and HFCS-55 (55% fructose and opened a new frontier for the sweetener and soft drink industries. Using a glucose isomerase, the starch in corn can be efficiently converted into glucose and then to various amounts of fructose. Hydrolysis of sucrose produces a 50:50 molar mixture of fructose and glucose. The primary difference is that these monosaccharides exist free in solution in HFCS, but in sucrose bonded together. The disaccharide sucrose is easily cleaved in the small intestine, so free fructose and glucose are absorbed from both sucrose and HFCS. The advantage to food manufacturers is that the free monosaccharide in HFCS provides better flavor enhancement, stability, freshness, texture, color, pourability, and consistency in foods in comparison to sucrose. The development of these inexpensive, sweet corn-based syrups made it profitable to replace sucrose (sugar and simple sugars with HFCS in our diet. In the present study, the replacement of sucrose with HFCS and its effect on the functionality and organoleptic properties of different food products were reviewed.

    Fructose-containing sugars, including sucrose and high fructose corn syrup (HFCS), have been implicated in the epidemics of obesity and type 2 diabetes. Few studies have evaluated the impact of perinatal exposure to these sugars on metabolic and physiological outcomes in the offspring. Using a rat model, offspring exposed to a maternal sucrose or HFCS diet during the prenatal and/or suckling periods were found to have altered adiposity and liver fat content and composition at weaning. Plasma levels of free fatty acids remained elevated in young adulthood, but consumption of a control diet following weaning appeared to ameliorate most other effects of perinatal exposure to a maternal high-sugar diet. Guidelines for maternal nutrition should advise limiting consumption of fructose-containing sugars, and it is particularly important that these recommendations include maternal nutrition during lactation. Perinatal exposure to excess maternal intake of added sugars, including fructose and sucrose, is associated with an increased risk of obesity and type 2 diabetes in adult life. However, it is unknown to what extent the type of sugar and the timing of exposure affect these outcomes. The aim of this study was to determine the impact of exposure to maternal consumption of a 10% (w/v) beverage containing sucrose or high fructose corn syrup-55 (HFCS-55) during the prenatal and/or suckling periods on offspring at 3 and 12 weeks, utilising a cross-fostering approach in a rodent model. Perinatal sucrose exposure decreased plasma glucose concentrations in offspring at 3 weeks, but did not alter glucose tolerance. Increased adiposity was observed in 3-week-old offspring exposed to sucrose or HFCS-55 during suckling, with increased hepatic fat content in HFCS-55-exposed offspring. In terms of specific fatty acids, hepatic monounsaturated (omega-7 and -9) fatty acid content was elevated at weaning, and was most pronounced in sucrose offspring exposed during both the prenatal and

    A novel approach for the resolution and quantitation of severely overlapped quaternary mixture of carbinoxamine maleate (CAR), pholcodine (PHL), ephedrine hydrochloride (EPH) and sunset yellow (SUN) in syrup was demonstrated utilizing different spectrophotometric assisted multivariate calibration methods. The applied methods have used different processing and pre-processing algorithms. The proposed methods were partial least squares (PLS), concentration residuals augmented classical least squares (CRACLS), and a novel method; continuous wavelet transforms coupled with partial least squares (CWT-PLS). These methods were applied to a training set in the concentration ranges of 40-100 μg/mL, 40-160 μg/mL, 100-500 μg/mL and 8-24 μg/mL for the four components, respectively. The utilized methods have not required any preliminary separation step or chemical pretreatment. The validity of the methods was evaluated by an external validation set. The selectivity of the developed methods was demonstrated by analyzing the drugs in their combined pharmaceutical formulation without any interference from additives. The obtained results were statistically compared with the official and reported methods where no significant difference was observed regarding both accuracy and precision.

    High-fructose corn syrup (HFCS) is an agro-source product and has been the most commonly used substitute for sugar as sweetener in food industry due to its low price and high solution property. In this study, the F55 HFCS, rich in fructose and glucose, was first tested for biomass and docosahexaenoic acid productions as a mixed carbon source by a newly isolated Aurantiochytrium sp.YLH70. After the compositions of the HFCS media were optimized, the results showed that the HFCS with additions of metal ion and vitamin at low concentrations was suitable for biomass and docosahexaenoic acid productions and the metal ion and sea salt had the most significant effects on biomass production. During the 5-l fed-batch fermentation, total HFCS containing 180 g l(-1) reducing sugar was consumed and yields of biomass, lipid, and DHA could reach 78.5, 51, and 20.1 g l(-1), respectively, at 114 h. Meanwhile, the daily productivity and the reducing sugar conversion yield for docosahexaenoic acid were up to 4.23 g l(-1)day(-1) and 0.11 g g(-1). The fatty acid profile of Aurantiochytrium sp.YLH70 showed that 46.4% of total fatty acid was docosahexaenoic acid, suggesting that Aurantiochytrium sp.YLH70 was a promising DHA producer.

    Maple syrup urine disease (MSUD) is a rare autosomal recessive genetic disorder caused by defects in the catabolism of the branched-chain amino acids (BCAAs). Classic form of MSUD (CMSUD) is caused by mutations in BCKDHA, BCKDHB, DBT genes mostly. In this study, we analyzed the clinical and genetic characteristics of two patients with CMSUD. Two homozygous mutations, c.517G > T (p.Asp173Tyr) and c.503G > A (p.Arg168His), both in the exon 5 of BCKDHB were detected respectively. The novel mutation p.Asp173Tyr of patient A, inherited from his parents, is predicted to affect conformation of protein by computer analysis. The reported mutation p.Arg168His observed in patient B seemed to occur in a maternal uniparental disomy inheritance manner. Review of related literature revealed that most missense mutations in exon 5 of BCKDHB in homozygous genotype often result in CMSUD because of its incorrect conformation, and exon 5 of BCKDHB might be a susceptible region. Thus the novel homozygous mutation p.Asp173Tyr and the founder homozygous mutation p.Arg168His may be responsible for the clinical presentation of the two CMSUD patients, facilitating the future genetic counselling and prenatal diagnosis.

    It has been suggested that withdrawal from sugar produces a set of symptoms that resemble those observed following withdrawal from opiate drugs. This study explored naltrexone-induced withdrawal in animals pre-exposed to acute, chronic, and intermittent high fructose corn syrup (HFCS) or acute and chronic heroin administration. Experiment 1 examined conditioned place avoidance (CPA) induced by different doses of naltrexone (0.01-1 mg/kg) in naïve male Sprague-Dawley rats. In experiment 2, rats received continuous or intermittent home cage HFCS access (0 or 50 %) prior to conditioning with 1 mg/kg naltrexone. In experiment 3, HFCS ingestion was increased by food restriction and rats were conditioned with 3 mg/kg naltrexone. In experiment 4, the timing and quantity of HFCS ingestion (0, 0.5, 1, 2 g/kg) was controlled by intragastric administration, and rats were conditioned with 1 mg/kg naltrexone. In experiment 5, rats received acute (2 mg/kg) or chronic heroin (3.5 mg/kg/day) prior to conditioning with 1 mg/kg naltrexone. Administration of naltrexone produced moderate conditioned place avoidance in naïve rats. Importantly, acute, continuous, and intermittent HFCS pre-exposure did not significantly amplify this effect, but acute and chronic heroin pre-exposure did. As assessed by CPA, these results in rats fail to support the hypothesis that an opioid antagonist can precipitate similar affective withdrawal states following pre-exposure to sugars and opiates.

    Full Text Available The American Heart Association (AHA has advocated that women and men not consume more than 100 and 150 kcal/day, respectively, from added sugars. These levels are currently exceeded by over 90% of the adult population in the United States. Few data exist on longer-term metabolic effects when sucrose and High Fructose Corn Syrup (HFCS, the principal sources of added dietary sugars, are consumed at levels typical of the general population. Sixty five overweight and obese individuals were placed on a eucaloric (weight stable diet for 10-weeks, which incorporated sucrose- or HFCS-sweetened, low-fat milk at 10% or 20% of calories in a randomized, double-blinded study. All groups responded similarly (interaction p > 0.05. There was no change in body weight in any of the groups over the 10-week study, or in systolic or diastolic blood pressure. Likewise, there were no changes in total cholesterol, triglycerides, low-density lipoprotein (LDL, or apolipoprotein B (Apo B. We conclude that (1 when consumed as part of a eucaloric diet fructose—when given with glucose (as normally consumed does not promote weight gain or an atherogenic lipid profile even when consumed at two to four times the level recently recommended by the AHA. (2 There were no differences between HFCS and sucrose on these parameters.

    Most inborn errors of metabolism (IEMs) are inherited in an autosomal recessive manner. IEMs are one of the major concerns in Iran due to its extensive consanguineous marriages. Herein, we report two patients with two co-existent IEMs: a girl affected by classic phenylketonuria (PKU) and maple syrup urine disease (MSUD) and a male patient affected with Sandhoff disease and PKU, where Sandhoff disease was suspected due to the presence of a cherry-red spot in the eyes at 6 months which is unrelated to PKU. Sequencing of candidate genes in the first patient revealed one novel and three recurrent compound heterozygous mutations of p.Ser231Pro and p.Ala300Ser in the PAH gene and p.Glu330Lys and p.Arg170Cys mutations in the BCKDHB gene. Genetic testing results in the second patient showed previously reported homozygous mutations of p.Arg261Gln in the PAH and p.Arg533Cys mutation in the HEXB gene. Genetic testing confirmed the clinical diagnosis of both diseases in both patients. To the best of our knowledge; this is the first report of the co-existence of two distinct genetic disorders in two individuals from Iran. Co-existent different IEMs in patients complicated the clinical diagnosis and management of the diseases.

    Full Text Available Abstract High fructose corn syrup (HFCS is one of the most used sweeteners in the food industry. Health concerns regarding the consumption of HFCS-containing foods have developed in parallel with the increasing amount of people who become overweight. This study was conducted to investigate whether HFCS-containing peach nectar (pn-HFCS consumption has more detrimental effects on anthropometrical and biochemical parameters compared with sucrose-containing peach nectar (pn-sucrose. Fifty-day-old Sprague Dawley rats were divided into three groups and were fed (A pn-HFCS + ad libitum chow, (B pn-sucrose + ad libitum chow and (C only ad libitum chow for 7 months. The percentage change in body weight (PCBW, body mass index (BMI, and Lee index were calculated, and serum triglyceride, glucose, insulin and leptin concentrations were measured. The PCBW, BMI, Lee index, serum triglyceride, glucose, insulin and leptin concentrations were insignificant among the three groups. We can suggest that peach nectar consumption resulted in more energy intake than the control and since pn-HFCS group consumed more chow than the pn-sucrose group. The results show that long term daily HFCS or sucrose consumption in peach nectar is not associated with weight gain and does not stimulate metabolic changes in Sprague Dawley rats.

    High fructose corn syrup (HFCS) is an alternative of liquid sweetener to sucrose that is isomerized by commercial glucose isomerase (GI). One-step production of 55 % HFCS by thermostable GI has been drawn more and more attentions. In this study, a new hyperthermophilic GI from Thermoanaerobacter ethanolicus CCSD1 (TEGI) was identified by genome mining, and then a 1317 bp fragment encoding the TEGI was synthesized and expressed in Escherichia coli BL21(DE3). To improve the activity of TEGI, two amino acid residues, Trp139 and Val186, around the active site and substrate-binding pocket based on the structural analysis and molecular docking were selected for site-directed mutagenesis. The specific activity of mutant TEGI-W139F/V186T was 2.3-fold and the value of k cat/K m was 1.86-fold as compared to the wild type TEGI, respectively. Thermostability of mutant TEGI-W139F/V186T at 90 °C for 24 h showed 1.21-fold extension than that of wild type TEGI. During the isomerization of glucose to fructose, the yield of fructose could maintain above 55.4 % by mutant TEGI-W139F/V186T as compared to 53.8 % by wild type TEGI at 90 °C. This study paved foundation for the production of 55 % HFCS using the thermostable TEGI.

    Full Text Available Maple syrup urine disease (MSUD, an autosomal recessive inborn error of metabolism due to defects in the branched-chain α-ketoacid dehydrogenase (BCKD complex, is commonly observed among other inherited metabolic disorders in the kingdom of Saudi Arabia. This report presents the results of mutation analysis of three of the four genes encoding the BCKD complex in 52 biochemically diagnosed MSUD patients originating from Saudi Arabia. The 25 mutations (20 novel detected spanned across the entire coding regions of the BCKHDA, BCKDHB and DBT genes. There were no mutations found in the DLD gene in this cohort of patients. Prediction effects, conservation and modelling of novel mutations demonstrated that all were predicted to be disease-causing. All mutations presented in a homozygous form and we did not detect the presence of a “founder” mutation in any of three genes. In addition, prenatal molecular genetic testing was successfully carried out on chorionic villus samples or amniocenteses in 10 expectant mothers with affected children with MSUD, molecularly characterized by this study.

    Levodropropizine is an oral non-opioid anti-tussive drug used in treatment of cough. A new generic 60 mg capsule formulation of levodropropizine has recently been developed. The aim of this study was to assess the pharmacokinetics and bioequivalence of the test (capsule) formulation and reference (syrup) formulation of levodropropizine (60 mg) in healthy, fasted, male Korean volunteers. This was a single-dose, randomized sequence, open-label, 2-period crossover study conducted in healthy male Korean volunteers in the fasted state at Kyung Hee University Medical Center (Seoul, Republic of Korea). A single oral dose of the test or reference formulation was followed by a 1-week washout period, after which subjects received the alternative formulation. Blood samples were collected at 0 (predose), 0.17, 0.33, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 8, and 12 hours after study drug administration. Plasma concentration of levodropropizine was determined using a validated liquid chromatography tandem mass spectrometry (LCMS/ MS) method. The formulations were considered bioequivalent if the 90% CIs for C(max), AUC(0-12h) and AUC(0-∞) were within the predetermined bioequivalence range (80 - 125%, according to the guidelines of the Korea Food and Drug Administration (Korea FDA)). Tolerability was evaluated throughout the study based on vital sign measurements, laboratory analysis (blood biochemistry, hematology, hepatic function and urinalysis) and subject interviews concerning adverse events (AEs). A total of 36 male Korean subjects (mean (SD) age, 23.9 (2.4) years (range 19 - 30 years); height, 176.2 (6.1) cm (range 161 - 190 cm); weight, 69.8 (9.1) kg (range 54.0 - 92.2 kg); body mass index, 22.4 (2.1) kg/m2 (range 19.1 - 28.3 kg/m2)) was enrolled and completed the study. The mean values for C(max), t(max), AUC(0-12h), and AUC(0-∞) with the test formulation of levodropropizine were 331.51 ng/ml, 0.60 hours, 784.32 ng×h/ml, and 825.82 ng×h/ml, respectively; for the reference

    To compare the flavor and taste preference of two acid-inhibitory therapies in healthy children aged between 5-11 years. A single-site, single-blind, taste test trial was conducted in which 111 children participated after parental consent. One teaspoonful (5 mL) of lansoprazole delayed-release oral suspension (strawberry-flavored) and ranitidine oral syrup (peppermint-flavored) were provided to each child with a 10-minute break between samples. Children tasted the sample, swished it in their mouth for 10 seconds, and then expectorated the sample. Spring water and crackers were used to clear the palate between samples. After each sampling, children were observed for facial expressions and asked to rate their degree of liking of each sample based on a 5-point facial hedonic scale (5=like it very much, 1=dislike it very much). Likes, dislikes, and product preference were recorded. Of the 56 female and 54 male children who tasted both samples, 95% (105/110) preferred lansoprazole. Taste and flavor were the most often cited reasons for preferring lansoprazole (61 and 17 children, respectively) while three children preferred the flavor of ranitidine oral syrup. Lansoprazole received a higher mean liking rating compared with ranitidine (mean liking scores of 4.1 and 2.2, respectively). There was no significant difference in the preference for lansoprazole between age groups and gender with the degree of liking scores ranging between 3.5-4.4. Forty-two children disliked the texture of the lansoprazole oral suspension, citing the granules (31/110), thickness (7/110), or consistency/texture (4/110), specifically. After sampling both products, 95% of children preferred the flavor and taste of the strawberry-flavored lansoprazole delayed-release oral suspension compared with the peppermint-flavored ranitidine oral syrup.

    Excess consumption of added sugars, including sucrose and high fructose corn syrup (HFCS-55), have been implicated in the global epidemics of obesity and type 2 diabetes. This study aimed to investigate and compare the impact of maternal consumption of sucrose or HFCS-55 during pregnancy and lactation on the metabolic health of the dam and her offspring at birth. Female Albino Wistar rats were given access to chow and water, in addition to a sucrose or HFCS-55 beverage (10% w/v) before, and during pregnancy and lactation. Maternal glucose tolerance was determined throughout the study, and a postmortem was conducted on dams following lactation, and on offspring within 24 h of birth. Sucrose and HFCS-55 consumption resulted in increased total energy intake compared with controls, however the increase from sucrose consumption was accompanied by a compensatory decrease in chow consumption. There was no effect of sucrose or HFCS-55 consumption on body weight, however sucrose consumption resulted in increased adiposity and elevated total plasma cholesterol in the dam, while HFCS-55 consumption resulted in increased plasma insulin and decreased plasma non-esterified fatty acids (NEFA). Maternal HFCS-55 consumption was associated with decreased relative liver weight and plasma NEFA in the offspring at birth. There was no effect of either treatment on pup weight at birth. These findings suggest that both sucrose and HFCS-55 consumption during pregnancy and lactation have the potential to impact negatively on maternal metabolic health, which may have adverse consequences for the long-term health of the offspring.

    Maple Syrup Urine Disease (MSUD) is an inborn error of metabolism caused by a deficiency of the branched-chain α-keto acid dehydrogenase complex activity. This blockage leads to accumulation of the branched-chain amino acids leucine, isoleucine and valine, as well as their corresponding α-keto acids and α-hydroxy acids. The affected patients present severe neurological symptoms, such as coma and seizures, as well as edema and cerebral atrophy. Considering that the mechanisms of the neurological symptoms presented by MSUD patients are still poorly understood, in this study, protein levels of apoptotic factors are measured, such as Bcl-2, Bcl-xL, Bax, caspase-3 and -8 in hippocampus and cerebral cortex of rats submitted to acute administration of branched-chain amino acids during their development. The results in this study demonstrated that BCAA acute exposure during the early postnatal period did not significantly change Bcl-2, Bcl-xL, Bax and caspase-8 protein levels. However, the Bax/Bcl-2 ratio and procaspase-3 protein levels were decreased in hippocampus. On the other hand, acute administration of BCAA in 30-day-old rats increase in Bax/Bcl-2 ratio followed by an increased caspase-3 activity in cerebral cortex, whereas BCAA induces apoptosis in hippocampus through activation and cleavage of caspase-3 and -8 without changing the Bax/Bcl-2 ratio. In conclusion, the results suggest that apoptosis could be of pivotal importance in the developmental neurotoxic effects of BCAA. In addition, the current studies also suggest that multiple mechanisms may be involved in BCAA-induced apoptosis in the cerebral cortex and hippocampus.

    The American public is increasingly concerned about risks associated with food additives like high-fructose corn syrup (HFCS). To promote its product as safe, the Corn Refiners Association (CRA) employed two forms of straw-person arguments. First, the CRA opportunistically misrepresented HFCS opposition as inept. Second, the CRA strategically chose to refute claims that were easier to defeat while remaining ambiguous about more complex points of contention. We argue that CRA's discursive contributions represented unreasonable yet sustainable use of straw-person arguments in debates surrounding health and risk.

    We developed a whole-cell surface plasmon resonance (SPR) sensor based on a leucine auxotroph of Escherichia coli displaying a gold-binding protein (GBP) in response to cell growth and applied this sensor to the diagnosis of maple syrup urine disease, which is represented by the elevated leucine level in blood. The leucine auxotroph was genetically engineered to grow displaying GBP in a proportion to the concentration of target amino acid leucine. The GBP expressed on the surface of the auxotrophs directly bound to the golden surface of an SPR chip without the need for any additional treatment or reagents, which consequently produced SPR signals used to determine leucine levels in a test sample. Gold nanoparticles (GNPs) were further applied to the SPR system, which significantly enhanced the signal intensity up to 10-fold by specifically binding to GBP expressed on the cell surface. Finally, the diagnostic utility of our system was demonstrated by its employment in reliably determining different statuses of maple syrup urine disease based on a known cutoff level of leucine. This new approach based on an amino acid-auxotrophic E. coli strain expressing a GBP that binds to an SPR sensor holds great promise for detection of other metabolic diseases of newborn babies including homocystinuria and phenylketonuria, which are also associated with abnormal levels of amino acids.

    Full Text Available Osmotic dehydration is becoming more popular as a complementary treatment in the processing of dehydrated foods, since it presents some advantages such as minimising heat damage to the colour and flavour, inhibiting enzymatic browning and thus dispensing the addition of sulphite and, mainly, reducing energy costs. The objective of the present study was to evaluate the effect of using inverted sugar and sucrose syrups as osmotic agents in the dehydration of mango. The conditions used in the dehydration process were: syrup/fruit ratio of 3:1 (v/w; temperature of 45ºC and constant stirring. The in natura and osmo-dehydrated fruits were evaluated in relation to pH, moisture content, water activity (a w and soluble solids (ºBrix. Solids incorporation and loss in mass after the dehydration process were also determined. The sensory acceptance of the in natura and osmo-dehydrated fruits was determined for the attributes of aroma, flavour, texture and overall acceptance using a hedonic scale. Osmotic dehydration resulted in a reduction in moisture content and water activity, an increase in Brix and maintenance of the pH. The treatment with inverted sugar syrup resulted in more significant alterations in moisture content, a w, Brix, solids incorporation and loss in mass than the treatment with sucrose syrup. Mangos osmo-dehydrated with inverted sugar (55.3% inversion rate syrup obtained acceptance similar to in natura mangos, this treatment being considered the most adequate for dehydration purposes.A desidratação osmótica tem se tornado uma tecnologia cada vez mais usual no processamento de alimentos desidratados, por apresentar vantagens como a redução nas perdas de cor e sabor durante o tratamento térmico, inibição do escurecimento enzimático, prescindindo da adição de agentes sulfitantes, e principalmente economia no consumo de energia.

    Maple syrup urine disease (MSUD) is a rare autosomal recessive disorder that affects the degradation of branched chain amino acids (BCAAs). Only a few cases of MSUD have been documented in Mainland China, and prenatal diagnosis has not been performed so far. In this report, 8 patients (4 girls and 4 boys) with MSUD from 8 unrelated Chinese families were diagnosed at the age of 9 days to 1 year and 8 months. The diagnosis was confirmed by serum BCAAs and genetic analyses. Among the 8 patients, only one was detected by newborn screening. The remaining 7 patients were admitted because of neurological disorders and underwent selective screening. Significantly elevated BCAAs were observed in 7 patients. One patient was diagnosed by post-mortem study. 12 mutations were found in the BCKDHA, BCKDHB and DBT genes. 11 of these mutations were novel: c.178G > T, c.491T > C, c.740A > G, c.1214_1219dupCCAACC and IVS6+1delG in BCKDHA; c.482T > G, c.508C > T, c.767A > G, c.768C > G and IVS4,-2A > C in BCKDHB; and c.1A > G in DBT. Only one mutation, c.659C > T in the BCKDHA gene, had been previously reported. 7 patients were treated by dietary intervention and symptomatic therapy. 6 of them showed clinical improvement. The mother of one patient who died from MSUD underwent amniocentesis during her second pregnancy. The BCAAs level in her amniotic fluid was normal. Only one heterozygous mutation, IVS4,-2A > C in the BCKDHB gene, was detected in the cultured amniocytes. The results revealed that the fetus was not affected by MSUD. Normal development and the blood BCAAs profile confirmed the prenatal diagnosis after birth. Thus, we identified eleven novel mutations associated with MSUD in the Chinese population. Prenatal diagnosis of MSUD was successfully performed on one fetus by genetic analysis of the cultured amniocytes. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Public health recommendations call for a reduction in added sugars; however, controversy exists over whether all nutritive sweeteners produce similar metabolic effects. The objective was to compare the effects of the chronic consumption of 3 nutritive sweeteners [honey, sucrose, and high-fructose corn syrup containing 55% fructose (HFCS55)] on circulating glucose, insulin, lipids, and inflammatory markers; body weight; and blood pressure in individuals with normal glucose tolerance (GT) and those with impaired glucose tolerance (IGT). In a crossover design, participants consumed daily, in random order, 50 g carbohydrate from assigned sweeteners for 2 wk with a 2- to 4-wk washout period between treatments. Participants included 28 GT and 27 IGT volunteers with a mean age of 38.9 ± 3.6 y and 52.1 ± 2.7 y, respectively, and a body mass index (in kg/m(2)) of 26 ± 0.8 and 31.5 ± 1.0, respectively. Body weight, blood pressure (BP), serum inflammatory markers, lipids, fasting glucose and insulin, and oral-glucose-tolerance tests (OGTTs) were completed pre- and post-treatment. The OGTT incremental areas under the curve (iAUCs) for glucose and insulin were determined and homeostasis model assessment of insulin resistance (HOMA-IR) scores were calculated. Body weight and serum glucose, insulin, inflammatory markers, and total and LDL-cholesterol concentrations were significantly higher in the IGT group than in the GT group at baseline. Glucose, insulin, HOMA-IR, and the OGTT iAUC for glucose or insulin did not differ by treatment, but all responses were significantly higher in the IGT group compared with the GT group. Body weight was unchanged by treatment. Systolic BP was unchanged, whereas diastolic BP was significantly lower in response to sugar intake across all treatments. An increase in high-sensitivity C-reactive protein (hsCRP) was observed in the IGT group in response to all sugars. No treatment effect was observed for interleukin 6. HDL cholesterol did not

    There is a link between joint and gut inflammation of unknown etiology in arthritis. Existing research indicates that regular consumption of high-fructose corn syrup sweetened (HFCS) soft drinks, but not diet soft drinks, may be associated with increased risk of seropositive rheumatoid arthritis (RA) in women, independent of other dietary and lifestyle factors. One unexplored hypothesis for this association is that fructose malabsorption, due to regular consumption of excess free fructose (EFF) and HFCS, contributes to fructose reactivity in the gastrointestinal tract and intestinal in situ formation of enFruAGEs, which once absorbed, travel beyond the intestinal boundaries to other tissues and promote inflammation. In separate studies, the accumulation of advanced glycation end-products has been associated with joint inflammation in RA. Objective of this study was to assess the association between EFF beverages intake and non-age, non-wear and tear-associated arthritis in US young adults. In this cross sectional study of 1209 adults aged 20-30y, (Nutrition and Health Examination Surveys 2003-2006) exposure variables were high EFF beverages, including HFCS sweetened soft drinks, and any combination of HFCS sweetened soft drinks, fruit drinks (FD) and apple juice, referred to as tEFF. Analyses of diet soda and diet FD were included for comparison. The outcome was self-reported arthritis. Rao Scott Ҳ(2) was used for prevalence differences and logistic regression for associations, adjusted for confounders. Young adults consuming any combination of high EFF beverages (tEFF) ⩾5 times/week (but not diet soda) were three times as likely to have arthritis as non/low consumers (odds ratios=3.01; p⩽0.021; 95% confidence intervals=1.20-7.59), independent of all covariates, including physical activity, other dietary factors, blood glucose and smoking. EFF beverage intake is significantly associated with arthritis in US adults aged 20-30 years, possibly due to the

    Increased energy intake is consistently observed in individuals consuming sugar-sweetened beverages (SSBs), likely mainly because of an inadequate satiety response to liquid calories. However, SSBs have a high content of fructose, the consumption of which acutely fails to trigger responses in key signals involved in energy homeostasis. It is unclear whether the fructose content of SSBs contributes to the increased energy intake in individuals drinking SSBs. We investigated whether the relative amounts of fructose and glucose in SSBs modifies ad libitum energy intake over 8 d in healthy adults without fructose malabsorption. We conducted 2 randomized, controlled, double-blind crossover studies to compare the effects of consuming 4 servings/d of a fructose-, glucose-, or aspartame-sweetened beverage (study A; n = 9) or a fructose-, glucose-, or high-fructose corn syrup (HFCS)-sweetened beverage (study B; n = 24) for 8 d on overall energy intake. SSBs were provided at 25% of estimated energy requirement, or an equivalent volume of the aspartame-sweetened beverage, and consumption was mandatory. All solid foods were provided at 125% of estimated energy requirements and were consumed ad libitum. In study A, ad libitum energy intake was 120% ± 10%, 117% ± 12%, and 102% ± 15% of estimated energy requirements when subjects consumed the fructose-, glucose-, and aspartame-sweetened beverages. Energy intake was significantly higher in the fructose and glucose phases than in the aspartame phase (P fructose and glucose phases (P = 0.462). In study B, total energy intake during the fructose, HFCS, and glucose phases was 116% ± 14%, 116% ± 16%, and 116% ± 16% of the subject's estimated total energy requirements (P = 0.880). In healthy adults, total 8-d ad libitum energy intake was increased in individuals consuming SSBs compared with aspartame-sweetened beverages. The energy overconsumption observed in individuals consuming SSBs occurred independently of the relative

    Full Text Available A utilização de açúcar líquido na indústria alimentícia constitui em vantagem nas aplicações onde o açúcar é adicionado em solução. O xarope de açúcar invertido reúne a elevada solubilidade da frutose à difícil cristalização da glicose, aumentando seu poder edulcorante e diminuindo os riscos de cristalização. Essas propriedades contribuem para aumentar o valor desses xaropes para uso em vários produtos alimentícios, sobretudo na indústria de refrigerantes. O produto de maior interesse comercial é aquele com nível de inversão próximo a 55%, pois nessa faixa a solubilidade é máxima possibilitando trabalhar com concentrações em torno de 76,5% de sólidos solúveis, diminuindo assim a susceptibilidade à contaminação microbiana, sem riscos de cristalização. O objetivo deste trabalho foi desenvolver as etapas de produção do xarope de açúcar invertido produzido a partir de resinas de troca-iônica, visando obter um produto final de alta qualidade que atenda às necessidades da indústria de refrigerantes, utilizando como ferramenta o planejamento experimental. O processo de obtenção do xarope invertido foi iniciado com a descoloração do xarope de sacarose através de duas colunas contendo resina aniônica, para então ser invertido pela eluição numa coluna de resina catiônica. O produto obtido foi isento de qualquer objeção ao paladar, inodoro, praticamente livre de cor (56 ICUMSA e hidroximetil furfural (11ppm.

    Published data supports the neuroprotective effects of several phenolic-containing natural products, including certain fruit, berries, spices, nuts, green tea, and olive oil. However, limited data are available for phenolic-containing plant-derived natural sweeteners including maple syrup. Herein, we investigated the neuroprotective effects of a chemically standardized phenolic-enriched maple syrup extract (MSX) using a combination of biophysical, in vitro, and in vivo studies. Based on biophysical data (Thioflavin T assay, transmission electron microscopy, circular dichroism, dynamic light scattering, and zeta potential), MSX reduced amyloid β1–42 peptide (Aβ1–42) fibrillation in a concentration-dependent manner (50–500 μg/mL) with similar effects as the neuroprotective polyphenol, resveratrol, at its highest test concentration (63.5% at 500 μg/mL vs. 77.3% at 50 μg/mL, respectively). MSX (100 μg/mL) decreased H2O2-induced oxidative stress (16.1% decrease in ROS levels compared to control), and down-regulated the production of lipopolysaccharide (LPS)-stimulated inflammatory markers (22.1, 19.9, 74.8, and 87.6% decrease in NOS, IL-6, PGE2, and TNFα levels, respectively, compared to control) in murine BV-2 microglial cells. Moreover, in a non-contact co-culture cell model, differentiated human SH-SY5Y neuronal cells were exposed to conditioned media from BV-2 cells treated with MSX (100 μg/mL) and LPS or LPS alone. MSX-BV-2 media increased SH-SY5Y cell viability by 13.8% compared to media collected from LPS-BV-2 treated cells. Also, MSX (10 μg/mL) showed protective effects against Aβ1–42 induced neurotoxicity and paralysis in Caenorhabditis elegans in vivo. These data support the potential neuroprotective effects of MSX warranting further studies on this natural product. PMID:27418278

    Published data supports the neuroprotective effects of several phenolic-containing natural products, including certain fruit, berries, spices, nuts, green tea, and olive oil. However, limited data are available for phenolic-containing plant-derived natural sweeteners including maple syrup. Herein, we investigated the neuroprotective effects of a chemically standardized phenolic-enriched maple syrup extract (MSX) using a combination of biophysical, in vitro, and in vivo studies. Based on biophysical data (Thioflavin T assay, transmission electron microscopy, circular dichroism, dynamic light scattering, and zeta potential), MSX reduced amyloid β 1-42 peptide (Aβ 1-42 ) fibrillation in a concentration-dependent manner (50-500 μg/mL) with similar effects as the neuroprotective polyphenol, resveratrol, at its highest test concentration (63.5 % at 500 μg/mL vs. 77.3 % at 50 μg/mL, respectively). MSX (100 μg/mL) decreased H 2 O 2 -induced oxidative stress (16.1 % decrease in ROS levels compared to control), and down-regulated the production of lipopolysaccharide (LPS)-stimulated inflammatory markers (22.1, 19.9, 74.8, and 87.6 % decrease in NOS, IL-6, PGE 2 , and TNFα levels, respectively, compared to control) in murine BV-2 microglial cells. Moreover, in a non-contact co-culture cell model, differentiated human SH-SY5Y neuronal cells were exposed to conditioned media from BV-2 cells treated with MSX (100 μg/mL) and LPS or LPS alone. MSX-BV-2 media increased SH-SY5Y cell viability by 13.8 % compared to media collected from LPS-BV-2 treated cells. Also, MSX (10 μg/mL) showed protective effects against Aβ 1-42 induced neurotoxicity and paralysis in Caenorhabditis elegans in vivo. These data support the potential neuroprotective effects of MSX warranting further studies on this natural product.

    Full Text Available Atualmente, a maioria dos fármacos apresenta grupamento amínico. Estes quando associados a açúcares redutores ou a outros adjuvantes farmacêuticos contendo carbonila, freqüentemente produzem problemas de estabilidade, comprometendo a idoneidade do produto. A Reação de Maillard pode explicar tal ocorrência. Neste trabalho estudou-se o comportamento de xarope contendo amina aromática, tendo em vista a associação de açúcares e aminas, a Reação de Maillard e problemas de estabilidade. O protótipo escolhido foi o cloridrato de metoclopramida, benzamida com atividade farmacológica antiemética. Amostras dos xaropes de cloridrato de metoclopramida foram mantidas em estufa a 40 °C por seis meses. Em intervalos regulares de tempo alíquotas foram retiradas e submetidas à análise pelo método de Bratton-Marshall, seguida de leitura espectrofotométrica. Não houve grande variação no teor do cloridrato de metoclopramida em relação ao teor de açúcar, sendo que foram preparadas amostras padronizadas dos xaropes de cloridrato de metoclopramida em diferentes concentrações de açúcar. Houve diminuição do teor do cloridrato de metoclopramida, da ordem de 50%, tanto para amostras padronizadas como para amostra comercial.Nowadays, most of the drugs have amine group in their structure. These drugs, when associated to sugar reducers, or other carbonyl excipients frequently produce dark stains or fading. The Maillard reaction can explain such occurrence. In this work, we have studied the behavior of syrups containing aromatic amines. It is known that association of sugars and amines can generate problems of stability. The chosen prototype was the metoclopramide hydrochloride, a benzamide, with anti-emetic pharmacological activity. Samples of the metoclopramide syrups were maintained in stove at 40 °C for six months. In regular time intervals aliquots were removed and submitted to quantitative determination by the Bratton

    Management of patients with maple syrup urine disease (MSUD) includes a low protein diet, supplemented with special formulas and constant monitoring of branched chain amino acids (BCAA). The gold standard for monitoring BCAA is plasma amino acid analysis using high performance liquid chromatography (HPLC). In a developing country like the Philippines, however, the cost of this test is prohibitive to the majority of the patients. In our center, dried blood spot leucine/isoleucine (leu/ile) levels analysed by thin layer chromatography (TLC) is often used to diagnose and monitor these patients. This study was done to determine the correlation of leu/ile levels using the two methods (TLC and HPLC). A total of 46 MSUD patients were referred to the Biochemical Genetics Laboratory of the Institute of Human Genetics (IHG) from July 2001 to January 2004. Thirty five samples were obtained from 18 of these patients (some patients were seen at IHG more than once), and paired determinations of plasma amino acid using TLC and HPLC were made. The remaining samples were either hemolyzed or were not analyzed. The correlation coefficient [rho denoted as ρ] was estimated at a 95% confidence level using the Fisher's Z transformation. Of the 18 patients, 12 were males. The youngest was 1 day old and the oldest was 5 years old. The majority had the classical type of MSUD and dietary protein was restricted to between 0.6 gram/kg/day to 1 gram/kg/day of natural protein. Using the first pairs of observation for these 18 patients, the correlation coefficient was 0.76 (95% C1:0.462 to 0.907). This suggest a strong correlation between the two methods. It is recommended that further studies be done to determine the potential of the dried blood spot leu/ile level by TLC as an alternative method that can be used in the diagnosis and monitoring of MSUD patients especially in a developing country.

    Maple syrup urine disease (MSUD) is a rare metabolic disorder associated with acute and chronic brain dysfunction. This condition has been shown to lead to macroscopic cerebral alterations that are visible on imaging studies. Cerebral oedema is widely considered to be detrimental for MSUD patients; however, the mechanisms involved are still poorly understood. Therefore, we investigated whether acute administration of branched-chain amino acids (BCAA) causes cerebral oedema, modifies the Na(+),K(+)-ATPase activity, affects the permeability of the blood-brain barrier (BBB) and alters the levels of cytokines in the hippocampus and cerebral cortex of 10-day-old rats. Additionally, we investigated the influence of concomitant administration of dexamethasone on the alterations caused by BCAA. Our results showed that the animals submitted to the model of MSUD exhibited an increase in the brain water content, both in the cerebral cortex and in the hippocampus. By investigating the mechanism of cerebral oedema, we discovered an association between H-BCAA and the Na(+),K(+)-ATPase activity and the permeability of the BBB to small molecules. Moreover, the H-BCAA administration increases Il-1β, IL-6 and TNF-α levels in the hippocampus and cerebral cortex, whereas IL-10 levels were decreased in the hippocampus. Interestingly, we showed that the administration of dexamethasone successfully reduced cerebral oedema, preventing the inhibition of Na(+),K(+)-ATPase activity, BBB breakdown and the increase in the cytokines levels. In conclusion, these findings suggest that dexamethasone can improve the acute cerebral oedema and brain injury associated with high levels of BCAA, either through a direct effect on brain capillary Na(+),K(+)-ATPase or through a generalized effect on the permeability of the BBB to all compounds.

  17. No differential effect of beverages sweetened with fructose, high-fructose corn syrup, or glucose on systemic or adipose tissue inflammation in normal-weight to obese adults: a randomized controlled trial1

    2016-01-01

    Background: Sugar-sweetened beverage (SSB) consumption and low-grade chronic inflammation are both independently associated with type 2 diabetes and cardiovascular disease. Fructose, a major component of SSBs, may acutely trigger inflammation, which may be one link between SSB consumption and cardiometabolic disease. Objective: We sought to determine whether beverages sweetened with fructose, high-fructose corn syrup (HFCS), and glucose differentially influence systemic inflammation [fasting plasma C-reactive protein and interleukin-6 (IL-6) as primary endpoints] acutely and before major changes in body weight. Secondary endpoints included adipose tissue inflammation, intestinal permeability, and plasma fetuin-A as potential mechanistic links between fructose intake and low-grade inflammation. Design: We conducted a randomized, controlled, double-blind, crossover design dietary intervention (the Diet and Systemic Inflammation Study) in 24 normal-weight to obese adults without fructose malabsorption. Participants drank 4 servings/d of fructose-, glucose-, or HFCS-sweetened beverages accounting for 25% of estimated calorie requirements while consuming a standardized diet ad libitum for three 8-d periods. Results: Subjects consumed 116% of their estimated calorie requirement while drinking the beverages with no difference in total energy intake or body weight between groups as reported previously. Fasting plasma concentrations of C-reactive protein and IL-6 did not differ significantly at the end of the 3 diet periods. We did not detect a consistent differential effect of the diets on measures of adipose tissue inflammation except for adiponectin gene expression in adipose tissue (P = 0.005), which was lowest after the glucose phase. We also did not detect consistent evidence of a differential impact of these sugars on measures of intestinal permeability (lactulose:mannitol test, plasma zonulin, and plasma lipopolysaccharide-binding protein). Conclusion: Excessive

Foram empregados: relação fruta - xarope de 1:10; dois níveis de temperatura da solução de desidratação, 40 e 50 °C; dois níveis de agitação, zero e 60 min-1; e tempo de imersão de 2 horas. Verificou-se que a desidratação em xarope não diluído de açúcar invertido foi o tratamento que provocou o maior aumento no teor de sólidos solúveis totais das amostras de abacaxi. Os parâmetros que caracterizam a cinética da desidratação osmótica apresentaram valores mais elevados para as fatias que foram desidratadas a 50 °C, sob agitação.This work consisted of evaluating the effect of the type of osmotic agent, degree of stirring, and temperature and concentration of the hypertonic solution on the kinetics of osmotic dehydration of sliced pineapple. The osmotic agents used here were sucrose in solutions with concentrations of 0.40, 0.44 and 0.47 g.mL-1, and undiluted inverted sugar syrup. Osmotic dehydration was carried out using a fruit to syrup weight ratio of 1:10, and employing two levels of temperature of the solutions, 40 and 50 °C, two shaking rates, 0 and 60 min-1, and a total immersion time of 2 hours. The results showed that immersion in undiluted inverted sugar caused a greater increase in the total soluble solids content in sliced fruit. The parameters characterizing the kinetics of osmotic dehydration showed higher values in the sliced fruit dehydrated in syrup at 40 to 50 °C under shaking.

    Maple syrup urine disease (MSUD) or branched-chain ketoaciduria is caused by a deficiency in the mitochondrial branched-chain {alpha}-ketoacid dehydrogenase (BCKAD) complex. The clinical manifestations are characterized by accumulation of branched chain amino and {alpha}-ketoacids, which leads to severe cerebral edema with seizures, ketoacidosis, and mental retardation. The BCKAD complex comprises three catalytic components, i.e., a decarboxylase (E1) consisting of two E1{alpha} (M{sub r} = 46,000) and two E1{Beta} (M{sub r} = 37,500) subunits, a transacylase (E2) that contains 24 lipoic acid-bearing subunits, and a dehydrogenase (E3), which is a homodimeric flavoprotein. MSUD is genetically heterogeneous, since mutations in the E1{alpha} subunit (type IA MSUD), the E1{Beta} subunit (type IB), the E2 subunit (type II) and the E3 subunit (type III) have been described. The functional consequences of certain mutations in the BCKAD complex have been studied. 23 refs., 3 figs.

    Dextromethorphan (3-methoxy-N-methylmorphinan), also known as "DXM" and "the poor man's PCP," is a synthetically produced drug that is available in more than 140 over-the-counter cough and cold preparations. Dextromethorphan (DXM) has overtaken codeine as the most widely used cough suppressant due to its availability, efficacy, and safety profile at directed doses. However, DXM is subject to abuse. When consumed at inappropriately high doses (over 1500 mg/day), DXM can induce a state of psychosis characterized by Phencyclidine (PCP)-like psychological symptoms, including delusions, hallucinations, and paranoia. We report a noteworthy case of severe dextromethorphan use disorder with dextromethorphan-induced psychotic disorder in a 40-year-old Caucasian female, whose symptoms remitted only following treatment with a combination of an antipsychotic and mood stabilizer. While some states have begun to limit the quantity of DXM sold or restrict sales to individuals over 18-years of age, there is currently no federal ban or restriction on DXM. Abuse of DXM, a readily available and typically inexpensive agent that is not detected on a standard urine drug screen, may be an under-recognized cause of substance-induced psychosis. It is imperative that clinicians are aware of the potential psychiatric sequelae of recreational DXM use.

    MSUD is a hereditary metabolic disorder that is characterized by impaired activity of the BCKADC. Liver transplantation has been approved as a treatment for some MSUD cases in which the control of BCAAs is insufficient. Although there have been several reports about DDLT for MSUD, few LDLT cases have been reported. Because either of parents who are heterozygote of this disease usually applies to be a candidate of donor in LDLT, the impairment of BCKADC activity of graft liver should be concerned. We performed LDLT for 10 month-old girl with a left lateral segment graft from her father. BCKADC activities of the patient and her parents were measured using lysates of lymphocytes isolated from peripheral blood specimen before the transplant. As a consequence, the activity of BCKADC of father was not inferior to a normal range. The patient tolerated the operation well. Postoperative course was uneventful and mixed milk was started at 8th POD. The serum BCAAs levels have remained within normal range. It should be necessary to follow the physical growth and mental development of the recipient in the future. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To rapidly and efficiently detect the presence of adulterants in honey, three-dimensional fluorescence spectroscopy (3DFS) technique was employed with the help of multivariate calibration. The data of 3D fluorescence spectra were compressed using characteristic extraction and the principal component analysis (PCA). Then, partial least squares (PLS) and back propagation neural network (BP-ANN) algorithms were used for modeling. The model was optimized by cross validation, and its performance was evaluated according to root mean square error of prediction (RMSEP) and correlation coefficient (R) in prediction set. The results showed that BP-ANN model was superior to PLS models, and the optimum prediction results of the mixed group (sunflower ± longan ± buckwheat ± rape) model were achieved as follow: RMSEP = 0.0235 and R = 0.9787 in the prediction set. The study demonstrated that the 3D fluorescence spectroscopy technique combined with multivariate calibration has high potential in rapid, nondestructive, and accurate quantitative analysis of honey adulteration.

    Classical MSUD is often fatal without appropriate medical interventions because of metabolic crisis. There are numerous reports suggesting the therapeutic potential of deceased donor liver transplantation for MSUD. However, the usefulness of LDLT for MSUD is unknown. We report a case of classical MSUD, which was successfully managed by LDLT from the patient's father at 1 year of age. Abnormal brain findings, which were cured with effective treatment, gradually disappeared after LDLT. The patient then developed normally. Findings from this case suggest the importance of LDLT for maintaining low leucine levels and subsequent normal neurological development. Although LDLT involves a modest surgical insult, LDLT with a related donor achieves acceptable leucine levels for life. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  12. Kefir peptides prevent high-fructose corn syrup-induced non-alcoholic fatty liver disease in a murine model by modulation of inflammation and the JAK2 signaling pathway.

    In recent years, people have changed their eating habits, and high-fructose-containing bubble tea has become very popular. High-fructose intake has been suggested to be a key factor that induces non-alcoholic fatty liver disease (NAFLD). Kefir, a fermented milk product composed of microbial symbionts, has demonstrated numerous biological activities, including antibacterial, antioxidant and immunostimulating effects. The present study aims to evaluate the effects of kefir peptides on high-fructose-induced hepatic steatosis and the possible molecular mechanism. An animal model of 30% high-fructose-induced NAFLD in C57BL/6J mice was established. The experiment is divided into the following six groups: (1) normal: H 2 O drinking water; (2) mock: H 2 O+30% fructose; (3) KL: low-dose kefir peptides (50 mg kg -1 )+30% fructose; (4) KM: medium-dose kefir peptides (100 mg kg -1 )+30% fructose; (5) KH: high-dose kefir peptides (150 mg kg -1 )+30% fructose; and (6) CFM: commercial fermented milk (100 mg kg -1 )+30% fructose. The results show that kefir peptides improve fatty liver syndrome by decreasing body weight, serum alanine aminotransferase, triglycerides, insulin and hepatic triglycerides, cholesterol, and free fatty acids as well as the inflammatory cytokines (TNF-α, IL-6 and IL-1β) that had been elevated in fructose-induced NAFLD mice. In addition, kefir peptides markedly increased phosphorylation of AMPK to downregulate its targeted enzymes, ACC (acetyl-CoA carboxylase) and SREBP-1c (sterol regulatory element-binding protein 1), and inhibited de novo lipogenesis. Furthermore, kefir peptides activated JAK2 to stimulate STAT3 phosphorylation, which can translocate to the nucleus, and upregulated several genes, including the CPT1 (carnitine palmitoyltransferase-1) involved in fatty acid oxidation. Our data have demonstrated that kefir peptides can improve the symptoms of NAFLD, including body weight, energy intake, inflammatory reaction and the formation of fatty liver by activating JAK2 signal transduction through the JAK2/STAT3 and JAK2/AMPK pathways in the high-fructose-induced fatty liver animal model. Therefore, kefir peptides may have the potential for clinical application for the prevention or treatment of clinical metabolic syndrome.

  13. Avaliação das propriedades físicas, químicas e sensorial de preferência de goiabas em calda industrializadas Physical, chemical and sensorial analyses of industrialized guava in syrup

    Full Text Available Quatro marcas de goiabas em calda foram submetidas a análises físico-químicas, de cor e textura instrumentais e teste sensorial de preferência, a fim de avaliar as diferenças entre os produtos comerciais. As mesmas análises foram efetuadas em uma goiaba in natura madura, a fim de avaliar os possíveis efeitos do processamento na qualidade do produto. De maneira geral, observou-se grandes diferenças entre os produtos das diferentes marcas, e muitas vezes entre os frutos de um mesmo fabricante. As análises químicas mostraram que o teor de açúcares da maior parte dos produtos está entre 22 e 30%, com exceção de uma amostra que mostrou um valor bem mais elevado (ao redor de 40%. A análise sensorial mostrou que esta amostra com maior teor de açúcares foi a mais preferida em relação à doçura. Na análise de cor foram observados menores valores de a* em relação à fruta in natura, possivelmente devido à degradação dos carotenóides da goiaba. A luminosidade das goiabas em calda também é maior que da fruta in natura, devido à presença dos açúcares. Esta entrada de açúcares na fruta junto com o processamento térmico utilizado pode ter causado possível gelificação da pectina, aumentando a dureza, firmeza e elasticidade de algumas amostras processadas, quando comparadas à fruta fresca. No entanto, em alguns casos foi visível o efeito de processamentos mais drásticos, que levaram à perda da estrutura celular, observada pelos baixos valores das propriedades mecânicas. Em relação à textura e aparência, a amostra mais dura foi a preferida.Four brands of canned guava were submitted to physico-chemical, sensory (preference test and instrumental color and texture analyses, in order to evaluate the differences between commercial products. The same analyses were made on a fresh, mature guava, to evaluate possible effects of processing on the quality of the final product. There were considerable differences between the distinct brands, and occasionally differences could be found between samples from the same manufacturer. The chemical analyses showed that most of the samples contained between 22 and 30% of sugar, except for one sample, which had a higher content, around 40%. The preference test showed that the consumers preferred the sweetness of the sample with the highest sugar content. Lower values for the chroma parameter a* were found in the commercial samples than in the fresh fruit, probably due to carotenoid degradation. The canned guava samples were lighter (higher values for L* than the fresh fruit, due to the presence of sugar. The penetration of sugar into the fruit during heat processing may have caused pectin gelation, increasing the hardness, firmness and elasticity of some of the processed samples as compared to the fresh fruit. However in some samples, drastic process conditions were readily apparent, leading to loss of cellular structure, which could be observed from the low values obtained for the mechanical properties. With respect to texture, the hardest sample was preferred.

    2009-01-01

    Full Text Available Abstract Mercury cell chlor-alkali products are used to produce thousands of other products including food ingredients such as citric acid, sodium benzoate, and high fructose corn syrup. High fructose corn syrup is used in food products to enhance shelf life. A pilot study was conducted to determine if high fructose corn syrup contains mercury, a toxic metal historically used as an anti-microbial. High fructose corn syrup samples were collected from three different manufacturers and analyzed for total mercury. The samples were found to contain levels of mercury ranging from below a detection limit of 0.005 to 0.570 micrograms mercury per gram of high fructose corn syrup. Average daily consumption of high fructose corn syrup is about 50 grams per person in the United States. With respect to total mercury exposure, it may be necessary to account for this source of mercury in the diet of children and sensitive populations.

    The U. S. maple tariff is a tax on maple syrup and sugar imports from Canada into the United States. An analysis of the maple tariff indicates that it was never very effective in protecting the domestic maple industry from foreign competition. The tariff has been especially ineffective since World War II. Its removal will not hurt the U. S. maple syrup industry.

  5. Аbоut a theoretical yield of glucose from starch

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Starch is the raw materials for production of crystal food glucose. With at enzyme conversion of the high purity starch, it is possible to receive glucosic syrups of a glucose equivalent (GE 98%, where there is about 95% glucose and maltose and maltotriose – of about 5%. Starch hydrolysis is carried out with a gain of solids. Thus, 100 kg of amylum is possible to give up to 109.81 kg of glucose syrup on dry basis. Taking in account the losses at manufacture steps a yield can decrease to 105.61 kg. The purified glucose syrup is concentrated up to 73–75% of dry matters and goes to a crystallization step. Crystallization of glucose is carried out in a supersaturated solution within 56–70 hours at reduced temperature from 46–48 °C to 24–26 °C, resulting a mixture of glucose crystals and an intercrystal run-off syrup called a massecuite. The crystallization process is stopped when a 50% of crystals content in massecuite is reached. At the same time glucose yield will be 105.61/2 = 52.8%. Crystallization is carried out according to the single-stage scheme, with partial return of the end product – hydrol into the hydrolised syrup. Then the massecuite is sent to a centrifugation step for dividing glucose crystals and a run-off syrup, which is partially returned to the initial syrup to reduce in GE. The second part of the run-off syrup goes to realization. It must be kept in mind: the higher GE of the glucose syrup sent to a crystallization step, the more quantity of a hydrol is possible to be returned to hydrolysed syrup. Therefore, it is in a resulted a higher yield of glucose crystals. On the basis of the carried-out calculations the computer program was made with which it is possible to define a theoretical glucose and a hydrol yield, while changing values of a hydrolysed syrup. The higher GE values of a hydrolysed syrup are the higher yield of crystal glucose and the lower one of hydrol are. So, at 98% GE of a hydrolysed syrup it is

    International Nuclear Information System (INIS)

    Palant, A.A.

    2007-01-01

    Investigation results are discussed on the process of pelletizing with the use of various binders (water, syrup, sulfite-alcoholic residue and bentonite) for flotation sulfide molybdenite concentrate (∼84 % MoS 2 ) of the Mongolian deposit. It is established that with the use of syrup rather strong pellets (>300 g/p) of desired size (2-3 mm) can be obtained at a binder flowrate of 1 kg per 100 kg of concentrate. The main advantage of using syrup instead of bentonite lies in the fact that in this instance no depletion of a molybdenum calcine obtained by oxidizing roasting of raw ore takes place due to syrup complete burning out. This affects positively subsequent hydrometallurgical conversion because of decreasing molybdenum losses with waste cakes [ru

    In this work, the efficacy of fig syrup, a Mediterranean fig derivative, as a nutraceutical supplement, was demonstrated. Fig syrup is a fruit concentrate used as a common ingredient in the preparation of typical foods, and particularly in cakes. In vitro assays were performed to determine the amount of nutraceutical ingredients, such as phenolic compounds (3.92 mg equivalent of gallic acid per g) and flavonoids (0.35 mg equivalent of catechin per g), while HPLC analyses provided specific information about the composition of antioxidants in the syrup. Furthermore, total antioxidant activity, scavenging properties against DPPH and peroxyl radicals, and the anticholinesterase activity, clearly showed the efficacy of the syrup in preventing damage induced by free radicals and, thus, the applicability of this food derivative as a nutraceutical supplement.

    2017-06-01

    Full Text Available Stability of vitamin C in stored fruit and sugar syrup of Japanese quince was tested. Vitamin C was measured in the fruit at harvest and after a few weeks of storage under normal atmospheric conditions. Sugar syrup obtained from the fruit was subjected to analysis before and after pasteurisation, and after several weeks of storage. The Chaenomeles genotypes tested were valuable in terms of vitamin C content. Storage significantly reduced the vitamin C content in the fruit, by 20% on average after 2 weeks of storage. The mechanical treatment and preparation of sugar syrup decreased the vitamin content by nearly two-thirds when compared with the fruit at harvest. Pasteurisation and storage of the sugar syrup contributed to further losses of vitamin C, reducing it to a very low level.

    Full Text Available Introduction. For future health planning of our country, the type and amount of drugs used for treatment of chronic diseases should be known. Therefore, in the present study the treatment regimen of asthmatic children in the city of Mashhad was studied. Methods. To study the different types of drugs in the treatment regimen of asthmatic children in the city of Mashhad, we evaluated the treatment regimen of 366 primary school children with asthma disease. Starting, maximum and duration of action of three different bronchodilators (salbutamol inhaler, salbutamol syrup, and theophylline syrup were compared. Findings. The results of the first part of this study showed that only 31.6 percent of asthmatic children had history of treatment and only 10.6 percent had current medication. In addition, most of the treated children (38.8 percent had only bronchodilator (salbutamol syrup in their treatment regimen. The effect of salbutamol inhaler on lung function tests starts in 5 min, salbutamol syrup in 15 min and theophylline syrup at 30 min after administration. The maximum response to salbutamol inhaler, salbutamol syrup, and theophylline syrup occurred 15 min, 4 hr and 3 hr after administration, respectively. The reduction of response to salbutamol inhaler occurs after 3 hr, but there was no any reduction in response to salbutamol and theophylline syrup during study period. Conclusion. The prevalence of asthma among children in the city of Mashhad is relatively high, but most of asthmatic children are not treated. Although the oral bronchodilator in mild asthma is effective, salbutamol inhaler is needed for emergency use.

    The results of electron paramagnetic resonance (EPR) study on commercially available juices from various fruits and different fruit contents: 25%, 40%, 50%, and 100%, homemade juices, nectars and concentrated fruit syrups, before and after gamma-irradiation are reported. In order to remove water from non- and irradiated samples all juices and nectars were filtered; the solid residue was washed with alcohol and dried at room temperature. Only concentrated fruit syrups were dried for 60 min at 40 °C in a standard laboratory oven. All samples under study show a singlet EPR line with g=2.0025 before irradiation with exception of concentrated fruit syrups, which are EPR silent. Irradiation of juice samples gives rise to complex EPR spectra which gradually transferred to “cellulose-like” EPR spectrum from 25% to 100% fruit content. Concentrated fruit syrups show typical “sugar-like“ spectra due to added saccharides. All EPR spectra are characteristic and can prove radiation treatment. The fading kinetics of radiation-induced EPR signals were studied for a period of 60 days after irradiation. - Highlights: • The EPR analysis of juices, nectars and syrups proves that the sample has been irradiated. • Two sample preparation procedures were used. • The stability of the radiation induced EPR signals was studied over 2 months. • Application of European standards can be extended for irradiated juices and syrups

  16. Pranlukast hydrate in the treatment of pediatric bronchial asthma

    2013-07-01

    Full Text Available Shigemi Yoshihara Department of Pediatrics, Dokkyo Medical University, Tochigi, Japan Abstract: Pranlukast hydrate is a potent, selective, orally active, cysteinyl leukotriene antagonist that binds at the type 1 receptor. It is used as a 10% dry syrup to treat asthma and allergic rhinitis in pediatric patients. In a 4-week, dose-finding study, a dose-dependent improvement in lung function was observed in pediatric patients with asthma at an optimal dose of 5.1–10 mg/kg/day. In a comparative, randomized, double-blind, 4-week multicenter trial, pranlukast dry syrup 7 mg/kg/day achieved significantly better final overall improvement (71.4% versus oxatomide 1 mg/kg/day (37.2% in pediatric patients older than one year with asthma. In two 12-week, open-label trials and in a long-term open-label trial of treatment for up to 24 months, pranlukast dry syrup improved asthma control over baseline values. In a prospective post-marketing surveillance study and a long-term follow-up study, the safety and efficacy of pranlukast dry syrup was confirmed in infants younger than one year with bronchial asthma. In a 4-week, open-label trial, pranlukast dry syrup improved overall health-related quality of life and physical and emotional domain scores over baseline in pediatric patients with asthma. In a randomized, multicenter, double-blind, placebo-controlled, two-period crossover trial, pranlukast dry syrup significantly inhibited exercise-induced bronchospasm in children with asthma compared with placebo. In a modified Childhood Asthma Control Test, pranlukast dry syrup was significantly more effective in controlling asthma in patients younger than 4 years with the common cold. These findings show that pranlukast is useful and beneficial for treating pediatric patients with bronchial asthma. Keywords: pranlukast, leukotriene receptor antagonist, pediatric asthma

  17. The catalytic effect of honey on formation of reducing sugars during sucrose hydrolysis

    Directory of Open Access Journals (Sweden)

    Radovanović Mirjana N.

    2017-01-01

    Full Text Available In commercial apiculture, beekepers usually remove honey from hives and replenish food reserves with sugar syrup. When honeybees use sugar syrup (sucrose solution, they break down sucrose into glucose and fructose. These processes exhaust and weaken bees. In order to prevent bee exhaustion resulting from this processing, bees should preferably be supplied with ready made food before winter, i.e., with syrup in which sucrose has already been inverted. Feeding with inverted syrups is the most popular way of honeybee feeding. Beekeepers usually prepare inverted syrups by adding a weak organic acid (citric, oxalic, acetic or lactic acid to sucrose solution at elevated temperatures. Inverted syrup production under uncontrolled pH, temperature and time conditions can cause the formation of 5-hydroxymethyl-2-furaldehyde (HMF, a compound harmful to bees. High quality inverted syrup can be obtained through the hydrolytic decomposition of sucrose by the enzyme invertase. Due to its invertase content, honey can be used as a biocatalyst for sucrose inversion. Invertase activity depends on the type, method and time of honey storage. This study evaluates the catalytic effect of acacia honey on formation of reducing sugars during hydrolysis of 50 wt.% sucrose solution. The ratio of reducing sugars and sucrose at 40°C, after 5 days of hydrolysis at a concentration of honey and 10 wt.% was 0.30 g reducing sugars/g of sucrose. The highest content of reducing sugars was achieved at a temperature of 35°C, after 48 h of invertion. In all samples of hydrolysates obtained at different temperatures (35–65°C, HMF was detected at concentrations of less than 4.32 mg kg–1. A high degree of negative correlation (coefficient of linearity –0.94 was established between parameters of volumetric and polarimetric measurements during the hydrolysis of sucrose.

    Full Text Available Scientific and practical researches on the development of technologies of functional pastries with quality indicators satisfying customer and market demands of small enterprises are highly relevant. The purpose of studies was to develop a technology of functional cake based on processed Jerusalem artichoke products - cellulose and syrup.The recipe of the cake “Stolichnyi” was taken as a control sample.Test cake samples were prepared with partial or full replacement of sugar by Jerusalem artichoke syrup (0–100% and raisins by Jerusalem artichoke fiber (0, 50, 100%. It was found that organoleptic quality indicators of products improved by the introduction of Jerusalem artichoke syrup instead of sugar, their specific volume decreased slightly compared to the control – by 1.9–3.0%.Specific volume of cakes increased compared to the control by 5.4–11%improved by the introduction of Jerusalem artichokefiber instead of raisins, but its surface became bumpier, there were deep cracks. Specific volume of products increased by 7.8–8.8%, the surface was convex, slightly bumpy with little nicked when Jerusalem artichoke syrup and fiberwere introduced together.The humidity and the alkalinity of samples practically unchanged. The sample prepared with full replacement of sugar by syrup and raisins by fiber of Jerusalem artichoke had the best quality indicators.During storage for 5 days the smallest changes in the crumb condition and flavor were observed in cake samples with complete replacement of sugar by Jerusalem artichoke syrup, the introduction of Jerusalem artichoke fiber resulted in a slight elasticity decrease and friability crumbimprovement.

    Full Text Available The problem of developing beer drinks with added fruits, berries or extract's of plant is very actual problem. The aim of this study was to investigate the possibility of using syrup and rose hips in technology Ales. In the work explored the form of the introduction of rose hips, as well as the stage of application, and the maximum allowable amount of additive. The proportion of syrup in different dose was 20 25 and 30% by weight of malt. Syrup made at the stage of wort boiling with hops. Rose hips were added to the number 15,20 and 25 g/l for 5 minutes before the end of wort boiling. The influence of introduced additives on the activity of yeast were studied. It is shown that the biomass growth and activity of yeast in all the variants of the experiment are practically the same. The article discusses the effect of different concentrations of rose hip syrup and insertion of the fruit on the fermentation and quality of final beer. The introduction of the investigated concentrations of the syrup does not impact greatly on the course of fermentation, physico-chemical parameters and organoleptic characteristics of the beverage. Samples with the addition of syrup to the basic characteristics are similar to control sample. They are distinguished caramel taste, aggravated by the increasing share of the syrup. It is shown that the optimal form to make the herbal supplement of rose hips in the technology of production of Ales are rose hips. The most balanced organoleptic characteristics was the sample with the rose hips in a quantity of 0,4 kg on 1 dal Ale.

    Full Text Available The effect of different types of energy feeding (sugar syrup, inverted sugar and juice of sugar-cane on beeswax production and its economic feasibility are evaluated. Twenty beehives of Africanized Apis mellifera were selected, and five were used for each type of feeding. The treatments were T1 (sugar-cane juice, T2 (sugar syrup and T3 (inverted sugar. Feedings was provided by Boardman feeders and the amount was adjusted according to consumption. A layer of beeswax was manually set up into the honeybee nest and beeswax built area was measured weekly. Total reducing sugar, calorimetry, dry matter and ashes of all feedings were analyzed. Data were analyzed by analysis of variance with Tukey’s test to determine differences among averages. The average consumption of inverted sugar was significantly lower than that of other treatments. The highest beeswax production average occurred in the sugar syrup treatment. The highest average of ashes, dry matter and reducing sugar occurred, respectively, in sugar-cane juice, inverted sugar and sugar syrup. Sugar syrup may be an alternative energy source for beeswax production, although sugar-cane juice may be more profitable.

    Oxidative damage is implicated in the etiology of cancer, cardiovascular disease, and other degenerative disorders. Recent nutritional research has focused on the antioxidant potential of foods, while current dietary recommendations are to increase the intake of antioxidant-rich foods rather than supplement specific nutrients. Many alternatives to refined sugar are available, including raw cane sugar, plant saps/syrups (eg, maple syrup, agave nectar), molasses, honey, and fruit sugars (eg, date sugar). Unrefined sweeteners were hypothesized to contain higher levels of antioxidants, similar to the contrast between whole and refined grain products. To compare the total antioxidant content of natural sweeteners as alternatives to refined sugar. The ferric-reducing ability of plasma (FRAP) assay was used to estimate total antioxidant capacity. Major brands of 12 types of sweeteners as well as refined white sugar and corn syrup were sampled from retail outlets in the United States. Substantial differences in total antioxidant content of different sweeteners were found. Refined sugar, corn syrup, and agave nectar contained minimal antioxidant activity (syrup, brown sugar, and honey showed intermediate antioxidant capacity (0.2 to 0.7 mmol FRAP/100 g). Based on an average intake of 130 g/day refined sugars and the antioxidant activity measured in typical diets, substituting alternative sweeteners could increase antioxidant intake an average of 2.6 mmol/day, similar to the amount found in a serving of berries or nuts. Many readily available alternatives to refined sugar offer the potential benefit of antioxidant activity.

    Full Text Available In recent years all over the world, medicinal plants are used quite a lot but side effects of biological and chemical contents and radiopharmaceutical interactions for each consumer in question aren't entirely well-known. The studies of plant origin drug interaction with radiopharmaceuticals are highly relevant and desired. One of them is passiflora syrup (Passiflora incarnata L., Passifloraceae which is widely used for depression, insomnia, anxiety and menopause period. The aim of current study is to evaluate possible effects of passiflora syrup on the biodistribution of 99mTc-DTPA and its blood cells uptake. DTPA was labeled with 99mTc radionuclide. Biodistribution studies were performed on male Wistar albino rats which were treated via oral feeding-gavage-method with either passiflora syrup or 0.9 % NaCl as control group for ten days. Blood samples were obtained by cardiac blood withdrawal from the rats and they were radiolabeled. The biodistribution results showed that the passiflora syrup decreased the uptake of 99mTc-DTPA in kidneys and in blood cells. 99mTc-DTPA being used widely as a kidney diagnostic agent in nuclear medicine seems to be interacting with orally taken passiflora. Passiflora syrup may modify the uptake of 99mTc-DTPA by kidney. The knowledge of this negative effect may contribute to reduce the risk of misdiagnosis and/or repetition of the examinations in nuclear medicine.

  3. EVALUATION OF FERMENTATION PARAMETERS DURING HIGH-GRAVITY BEER PRODUCTION

    Full Text Available A large number of advantages are obtained from the use of highly concentrated worts during the production of beer in a process referred to as "high-gravity". However, problems related to slow or stuck fermentations, which cause the lower productivity and possibility of contamination, are encountered. This study examines the influence of factors pH, percentage of corn syrup, initial wort concentration and fermentation temperature on the fermentation parameters, namely productivity, wort attenuation and the yield coefficient for sugar-to-ethanol conversion. The results show that productivity increased when the higher temperature, the higher wort concentration and the lower syrup percentage were used, while wort attenuation increased when lower wort concentration and no syrup were used. The yield coefficient for sugar-to-ethanol conversion was not influenced by any of the factors studied.

    2014-06-18

    The fate of aflatoxins during processing of contaminated almonds into nougat, pastries, and almond syrup was evaluated by testing the effect of each processing step (blanching, peeling, roasting, caramelization, cooking, and water infusion) on the distribution and levels of aflatoxins. Blanching and peeling did not reduce total aflatoxins that were distributed between peeled almonds (90-93%) and skins (7-10%). Roasting of peeled almonds reduced up to 50% of aflatoxins. Up to 70% reduction of aflatoxins was observed during preparation and cooking of almond nougat in caramelized sugar. Aflatoxins were substantially stable during preparation and cooking of almond pastries. The whole process of almond syrup preparation produced a marked increase of total aflatoxins (up to 270%) that were distributed between syrup (18-25%) and spent almonds (75-82%). The increase of total aflatoxins was probably due to the activation of almond enzymes during the infusion step that released free aflatoxins from masked aflatoxins.

    2013-12-01

    Full Text Available Glyoxal (GO and methylglyoxal (MGO, two -dicarbonyl compounds (RCS found in humans, cause carbonyl stress following the formation of advanced glycation end products (AGEs. Both are linked to many chronic diseases. Foods, the extrinsic source, could cause the increase of RCS levels in physiological conditions. Previous data showed that high fructose corn syrup is the major source of RCS in beverages. Because of increasing consumption of syrup-sweetened beverages in Thailand, we aimed to find the GO, MGO, sugar contents, and their quantity relationship. We discovered that 70 different types of beverages contained extremely high levels of GO and MGO at maximum level of 333 and 1,208 μg/ml, respectively. All commercial syrup tested contained dicarbonyl contents, and statistics tests showed strong significant correlation between monosaccharide sugar and RCS. The total sugar contents of more than 20 tested was higher than the current daily recommendation for sugar intake to maintain health.

    2015-12-01

    Three Tunisian date varieties, Deglet Nour, Kentichi and Allig, served to produce syrups and powders, which were then examined for their physico-chemical composition and antioxidant properties. Different proportions of these sweetening-like agents were incorporated to produce nine different formulations of dairy desserts, with lower amount of added sugars to avoid any artificial flavoring or coloring agents. Sensory and color evaluation data revealed that incorporating Deglet Nour and Kentichi syrup offers the most desirable formulation. Furthermore, syrup polysaccharides and fibers contribute to better maintain the final product texture. In addition, date by-products create a good source of natural thickening agents, involved in enhancing apparent viscosity and spontaneous exudation. Thanks to their high content in phenolic compounds, date by-products considerably improve antioxidant activities of the formulated desserts. Therefore, they could be valued as natural ingredients in the formulation of novel dairy products with high nutritional-properties. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Liang, Sihui; Were, Lilian M

    2018-02-15

    Sunflower butter use as an allergen-free alternative to tree and legume nut butter in baking is limited by chlorogenic acid induced greening that occurs at alkaline pH. Limited information is available on controlling this greening in a food matrix. This study examined how different liquid sweeteners and relative humidity influenced greening of sunflower butter cookies. Doughs had similar initial pH (7.52-7.66) which increased to 8.44-9.13 after baking as ranked: xylitol>maple syrup>corn syrup>honey>agave syrup. Cookies made with maple syrup had the highest moisture and greening corresponding with lowest free chlorogenic acid. The % greening followed the same trend as greening intensity, and was positively correlated (r=0.9101) with chlorogenic-lysine adduct content. Our findings provide an ingredient solution to controlling greening, as results demonstrate that greening can be promoted with high relative humidity storage, and use of high moisture and pH ingredients. Unwanted greening can be inhibited by simply changing the liquid sweetener. Copyright © 2017 Elsevier Ltd. All rights reserved.
