The only effective treatment for CD is a strict lifelong renunciation of gluten-containing foods. Currently, the cereal products designed to meet the requirements of CD patients, especially gluten-free bread, are scarce, of low quality and poor flavor. Therefore, preparation of high quality and affordable bread for coeliac patients was the main objective of this study. Three kinds of gluten-free bread were prepared, in which wheat flour was substituted with rice and corn flour at a ratio of 5:1, respectively. Gluten was substituted using different hydrocolloids: 1% xanthan and 1% carrageenan (Mix A), GFB A;1% xanthan and 1% pectin (Mix B), GFB B;and 1% carrageenan and 1% pectin (Mix C), GFB C. These three types of bread were compared to control bread produced from wheat flour (WB). Sponge and dough method with some modifications was used to produce the bread samples with a developed formula (0.8% yeast, 4.0% sugar, 2% salt, 7.0% shortening, 2.0% non-fat dry milk, and 1% sodium stearoyl lactylate (SSL)). Determination of the chemical composition, rheological properties and physical characteristics, as well as sensory evaluation of the bread samples, was undertaken. Results showed that the moisture content of WB bread (control) was significantly lower than that of all types of gluten-free bread, and there was no significant difference in ash, protein, and lipid contents among the gluten-free bread samples. GFB A, GFB B and GFB C displayed no significant differences in their specific volumes. The sensory evaluation showed that GFB C received the lowest sensory evaluation score. Therefore, GFB A and GFB B were the best gluten-free samples.展开更多

Am...The effects of different vegetable flours (broccoli, cauliflower, artichoke, fennel, zucchini and mushroom) added to gluten-free bread on sensory quality, antioxidant properties and glycemic response were assessed. Among the vegetable flours, the addition of fennel flour significantly improved sensory bread quality. Artichoke flour has the highest phenolic (26.51 ± 1.92 mg/g dw) and flavonoid content (26.43 ± 1.93 mg/g dw). Even though the content of total phenol and flavonoids in vegetable flours was higher when compared to supplemented bread, the addition of artichoke and zucchini flours increased the total phenolic and flavonoid content and improved antioxidant activity. The incorporation of high level of vegetable flours (15%) also decreased the glycemic index of bread, in particular with artichoke and zucchini flours (59 ± 1.21 and 62 ± 0.49, respectively). To sum up, the results are very interesting because the addition of vegetable flours into gluten-free bread can improve nutritional and sensory properties of bread.展开更多

The present study was carried out to produce gluten free flat bread and biscuits with good quality. The ingredients under this study were cassava flour, rice flour, extruded soy protein (ESP) and pumpkin powder. Four levels of ESP were used for production of flat bread and biscuits: 2.5%, 5%, 7.5% and 10% for flat bread and 5%, 10%, 15% and 20% levels for biscuits. Results of flat bread samples showed that protein, fat, ash and fiber contents increased in all samples as increasing the level of ESP. Flat bread at level 10% ESP had the highest value of β-carotene. Alkaline water retention capacity (AWRC) at zero time and 24 h of flat bread storage had high values for levels 2.5% and 5% ESP. Water holding capacity (WHC) increased insignificantly by increasing the level of ESP. Color measurements revealed that the lightness decreased and the redness increased with increasing the level of ESP. Sensory evaluation of flat bread revealed that 2.5% followed by 5% ESP level had high score of overall acceptability. Physical properties of biscuits indicated that as the level of ESP increased the diameter, thickness, volume and specific volume decreased. Biscuits sample with 20% ESP had the highest values of protein, fat, ash and fiber but the lowest in total carbohydrates. Also β-carotene and vitamin A content increased in biscuit samples. Caloric values of biscuits in all treated samples were lower than control. Lightness decreased while redness increased with increasing the level of ESP. Data of texture profile analysis (TPA) showed that hardness and adhesiveness (g) increased as ESP level increased. Sensory evaluation of biscuits showed that addition of ESP at 20% level decreased significantly texture score from 9.51 to 6.61 (P < 0.05) but insignificantly affected the other sensory scores.展开更多

Ancient whole grain gluten-free flatbreads were prepared with quinoa, teff, amaranth and buckwheat flours. Dough formulations contained flour, salt and water. Ingredients were mixed for 5 min using table top Kitchen Aid mixer at stir setting 1. Dough was equilibrated for 30 min. 65 g of dough was placed between two sheets of nonstick parchment paper and pressed to 17 cm round flatbreads in a Tortilla Chapatti Press. Each flatbread was cooked for two minutes (one minute each side) in using Flatbread Maker. Taste panels of 64 inhouse volunteers determined that Taste/Flavor of quinoa, teff and amaranth flatbreads were similar and significantly (P ≤ 0.05) better than those for buckwheat flatbread. The taste panel determined ancient whole grain gluten-free flatbreads had acceptance of quinoa 84%, teff 72%, amaranth 66% and buckwheat 38%. Each ancient whole grain gluten-free flatbread contained 25 - 30 g whole grain and 4 - 5 g protein. Quinoa, teff and amaranth one flatbread contained 2 - 3 g dietary fiber, whereas buckwheat flatbread contained 8 g dietary fiber. Consuming two whole grain gluten-free flatbreads with two meals (total = 4) would give 4 - 32 g of dietary fiber. The USDA food guide recom mends that at least 1/2 of all the grains eaten should be whole grains. The FDA allows food Health Claim labels for food containing 51% whole gains and 11 g of dietary fiber. The gluten sensitive individuals would enjoy tasty, health promoting, ancient whole grain easy to make flatbreads. These recipes offer consumers additional nutritious gluten-free choices and would lead to in crease in whole grain consumption.展开更多

The only treatment for CD is a strict, lifelong gluten-free diet. With a prevalence rate of about one in 100-133 people worldwide. Celiac disease is wide-spread across the globe. Unlike traditional allergies, which cause immediate reactions, gluten sensitivity is harder to pin down since it manifests gradually and in various forms like headaches, stomach cramps, bloating, anxiety, and depression. Due to complicated diagnosis procedure and lack of awareness, many cases are either misdiagnosed or not at all diagnosed in India and USA. In spite of high growth, gluten-free foods are facing problems to grain ground in Asian market, due to high price, lack of awareness about the products, large number of un-diagnosed cases and inefficient value chain for gluten-free products. One of the major issues in India and USA is very high prices of gluten-free foods as compared to regular food products. Globally, the market potential of gluten free products is estimated to be USD 4639.13 Million and USD 7594.43 Million in 2015 and 2020 respectively. The global gluten free food market is projected to grow with a CAGR between 9 percent and 10.2 percent during 2016-2022. The study on consumer preference of gluten-free foods would enable manufacturers of gluten-free foods to understand the current and evolving expectations of consumers and to design the products according. Study of two countries i.e., India and USA would enable manufacturers to understand the difference in choices and preferences related to gluten-free foods for both the nations. This study would help manufacturers of alternative wheat product to form the concrete marketing and product development strategy based on recent consumer behavior trends.展开更多

So, the aim of this work was to study the effect of partial substitution of rice flour at 20%, 30% and 40% with sorghum and germinated chickpea flours on rheological, physical, sensory properties and staling rate of prepared gluten-free cake. Obtained results showed that germinated chickpea flour had the highest contents of crude protein (23.62%), lipids (4.89%) and crude fibers (5.76%) as compared to other grain flours. Gradual increase in gelatinization temperature and decrease in maximum viscosity and setback were fond of cake batters with increasing the substituting levels of rice flour from 20% to 40% with sorghum or germinated chickpea flours in comparison to rice flour batter. No significant difference was observed in specific volume between rice cake and cake containing 20% of germinated chickpea and sorghum flours which given 2.71, 2.62 and 2.56 cm3/g, respectively. Data also revealed that gluten-free cake lightness (L*) and total intensity significantly increased with 40% of sorghum flour followed by 30 and 20% of sorghum flour. Substitution of 40% rice flour with germinated chickpea flour resulted in significant high in redness (a*), yellowness (b*) and chroma of gluten-free cake being 11.95, 33.72 and 35.77, respectively followed by substituted levels 30% and 20% which attributed to their natural yellow pigments compared with other investigated samples. Overall acceptability of gluten-free cakes was improved after adding 20, 30% of sorghum flour and 20% of germinated chickpea flour which being 90.7, 88.6 and 87.5, respectively compared to rice flour cake (88.4). Rice flour cake was more freshness than wheat flour cake and other treatments during storage duration. After 6 days, rice cake had significant high freshness (306.2%) followed by gluten-free cake samples with 20% of sorghum or germinated chickpea flours which given 294.5% and 289.4%, respectively. Generally, it could be concluded that the quality and nutritional properties of gluten-free rice cakes could be improved when using 20%, 30% of sorghum flour and 20% of germinated chickpea flour as substitution levels of rice flour.展开更多

LF up to 40% and BF flour up to 20% level were partially replaced with corn starch and rice flour mix in the gluten free cake recipe. Cake dough properties (specific gravity and pH), cake properties (weight, volume, symmetry and uniformity index, hardness), crust and crumb color values were investigated. High addition levels of LF decreased the pH values of the dough. Compared to control, volume index of the cakes improved with BF at 5% addition level or LF up to 20% level. While minimum level of the LF/BF gave softer cake texture, high substitution levels of LF (30%-40%) and BF (15%-20%) had detrimental effect on softness of the samples. All addition level of the LF increased the darkness and yellowness of the cake's crust and crumb, whereas BF above 5% level decreased lightness and yellowness of the samples. The high levels of LF (30%-40%) and BF (15%-20%) had reducing effect all physical properties of gluten-free cake samples.展开更多

Whole grain, fusilli pasta was prepared with teff, buckwheat, quinoa and amaranth flours. These ancient grains are called “Super Foods” due to their ideal essential amino acids and mineral profiles. Dough formulations contained 95% whole grain flour and 5% guar gum. Taste panels of 62 in-house volunteers judged amaranth pasta significantly (p ≤ 0.05) higher in color/appearance than other pastas tested. Odor/aroma of buckwheat pasta and texture/mouth-feel of teff pasta were significantly better than quinoa and amaranth pasta. Acceptance and taste/flavor of teff and buckwheat pasta were similar and significantly higher than quinoa and amaranth pasta (teff = buckwheat > quinoa > amaranth). The USDA food guide recommends that at least 1/2 of all the grains eaten should be whole grains. The FDA allows food Health Claim labels for food containing 51% whole gains and 11 g of dietary fiber per serving. Novel health promoting whole grain, good source of protein, gluten-free, egg-free (no chemicals added) pasta had acceptance of teff 87%, buckwheat 82%, quinoa 61% and amaranth 15%. Amaranth pasta needs improvement in several sensory attributes by fortification, processing and/or use of other cultivars for the desired results. Ancient whole grain, gluten-free, egg-free pasta would increase whole grain consumption and offer a healthy option to vegetarians as well as to gluten sensitive individuals.展开更多
文摘Adding different percentages 1%, 3% and 5% of fenugreek flour depending on maize flour base to gluten free bread recipe for making tanoor bread was used to improve the tanoor bread quality, in term of sensory properties like volume, crust, color, symmetry, bake uniformity, texture, grain, aroma and taste. Also some rheological properties like gelatinization temperature and maximum viscosity of dough with bread keeping quality were used. The aim of this work is to produce suitable bread with maintaining the bread quality by selecting the suitable percentage to produce gluten free bread for people who suffering from celiac diseases and its contribution to health benefits. Significant differences were observed by using 5% of fenugreek flour in term of gelatinization temperature, maximum viscosity, breed keeping quality and volume. While using 1% of fenugreek flour significantly improved symmetry value, bread texture, crumb color, aroma and taste.
文摘Coeliac disease (CD) is a common lifelong disorder with small bowel malabsorption and gluten intolerance. The only effective treatment for CD is a strict lifelong renunciation of gluten-containing foods. Currently, the cereal products designed to meet the requirements of CD patients, especially gluten-free bread, are scarce, of low quality and poor flavor. Therefore, preparation of high quality and affordable bread for coeliac patients was the main objective of this study. Three kinds of gluten-free bread were prepared, in which wheat flour was substituted with rice and corn flour at a ratio of 5:1, respectively. Gluten was substituted using different hydrocolloids: 1% xanthan and 1% carrageenan (Mix A), GFB A;1% xanthan and 1% pectin (Mix B), GFB B;and 1% carrageenan and 1% pectin (Mix C), GFB C. These three types of bread were compared to control bread produced from wheat flour (WB). Sponge and dough method with some modifications was used to produce the bread samples with a developed formula (0.8% yeast, 4.0% sugar, 2% salt, 7.0% shortening, 2.0% non-fat dry milk, and 1% sodium stearoyl lactylate (SSL)). Determination of the chemical composition, rheological properties and physical characteristics, as well as sensory evaluation of the bread samples, was undertaken. Results showed that the moisture content of WB bread (control) was significantly lower than that of all types of gluten-free bread, and there was no significant difference in ash, protein, and lipid contents among the gluten-free bread samples. GFB A, GFB B and GFB C displayed no significant differences in their specific volumes. The sensory evaluation showed that GFB C received the lowest sensory evaluation score. Therefore, GFB A and GFB B were the best gluten-free samples.
文摘The effects of different vegetable flours (broccoli, cauliflower, artichoke, fennel, zucchini and mushroom) added to gluten-free bread on sensory quality, antioxidant properties and glycemic response were assessed. Among the vegetable flours, the addition of fennel flour significantly improved sensory bread quality. Artichoke flour has the highest phenolic (26.51 ± 1.92 mg/g dw) and flavonoid content (26.43 ± 1.93 mg/g dw). Even though the content of total phenol and flavonoids in vegetable flours was higher when compared to supplemented bread, the addition of artichoke and zucchini flours increased the total phenolic and flavonoid content and improved antioxidant activity. The incorporation of high level of vegetable flours (15%) also decreased the glycemic index of bread, in particular with artichoke and zucchini flours (59 ± 1.21 and 62 ± 0.49, respectively). To sum up, the results are very interesting because the addition of vegetable flours into gluten-free bread can improve nutritional and sensory properties of bread.
文摘Soy protein isolate and egg white protein were added to cassava-banana gluten-free pasta and the effects on the nutritional quality,digestibility properties,protein digestibility corrected amino acid(PDCAA),and sensory acceptance of the pasta was observed.Banana-cassava composite flour(75:25)was blended with soy protein isolate or egg white protein at the following rates:0,5,10,and 15 g/100 g flour.Cooked pasta samples were analysed for total phenolic content(TPC),antioxidant activity,amino acid profiles,protein content,starch digestibility,protein digestibility and protein digestibility corrected amino acid score(PDCAAS).Addition of both proteins decreased starch digestibility,increased protein digestibility,improved the balance of the amino acid profile,and PDCAAS whereas only soy protein isolate enhanced the TPC and antioxidant capacity of the banana-cassava pasta.An egg white protein-fortified banana-cassava pasta had better customer acceptance and purchase intent than soy protein isolate inclusion.
文摘In recent years, there has been an increase in demand of gluten free products that are suitable for people with celiac disease. The present study was carried out to produce gluten free flat bread and biscuits with good quality. The ingredients under this study were cassava flour, rice flour, extruded soy protein (ESP) and pumpkin powder. Four levels of ESP were used for production of flat bread and biscuits: 2.5%, 5%, 7.5% and 10% for flat bread and 5%, 10%, 15% and 20% levels for biscuits. Results of flat bread samples showed that protein, fat, ash and fiber contents increased in all samples as increasing the level of ESP. Flat bread at level 10% ESP had the highest value of β-carotene. Alkaline water retention capacity (AWRC) at zero time and 24 h of flat bread storage had high values for levels 2.5% and 5% ESP. Water holding capacity (WHC) increased insignificantly by increasing the level of ESP. Color measurements revealed that the lightness decreased and the redness increased with increasing the level of ESP. Sensory evaluation of flat bread revealed that 2.5% followed by 5% ESP level had high score of overall acceptability. Physical properties of biscuits indicated that as the level of ESP increased the diameter, thickness, volume and specific volume decreased. Biscuits sample with 20% ESP had the highest values of protein, fat, ash and fiber but the lowest in total carbohydrates. Also β-carotene and vitamin A content increased in biscuit samples. Caloric values of biscuits in all treated samples were lower than control. Lightness decreased while redness increased with increasing the level of ESP. Data of texture profile analysis (TPA) showed that hardness and adhesiveness (g) increased as ESP level increased. Sensory evaluation of biscuits showed that addition of ESP at 20% level decreased significantly texture score from 9.51 to 6.61 (P < 0.05) but insignificantly affected the other sensory scores.

文摘Bread wheat(Triticum aestivum)is a staple food crop worldwide.The genetic dissection of important nutrient traits is essential for the biofortification of wheat to meet the nutritional needs of the world's growing population.Here,45,298 single-nucleotide polymorphisms(SNPs)from 55K chip arrays were used to genotype a panel of 768 wheat cultivars,and a total of 154 quantitative trait loci(QTLs)were detected for eight traits under three environments by genome-wide association study(GWAS).Three QTLs(qMn-3B.1,qFe-3B.4,and qSe-3B.1/qFe-3B.6)detected repeatedly under different environments or traits were subjected to subsequent analyses based on linkage disequilibrium decay and the P-values of significant SNPs.Significant SNPs in the three QTL regions formed six haplotypes for qMn-3B.1,three haplotypes for qFe-3B.4,and three haplotypes for qSe-3B.1/qFe-3B.6.Phenotypic analysis revealed significant differences among haplotypes.These results indicated that the concentrations of several nutrient elements have been modified during the domestication of landraces to modern wheat.Based on the QTL regions,we identified 15 high-confidence genes,eight of which were stably expressed in different tissues and/or developmental stages.TraesCS3B02G046100 in qMn-3B.1 and TraesCS3B02G199500 in qSe-3B.1/qFe-3B.6 were both inferred to interact with metal ions according to the Gene Ontology(GO)analysis.TraesCS3B02G199000,which belongs to qSe-3B.1/qFe-3B.6,was determined to be a member of the WRKY gene family.Overall,this study provides several reliable QTLs that may significantly affect the concentrations of nutrient elements in wheat grain,and this information will facilitate the breeding of wheat cultivars with improved grain properties.
文摘BACKGROUND Nutrition recommendations in patients with type 2 diabetes mellitus(T2DM)are to consume rye or integral bread instead of white bread.A positive effect on glucoregulation has been achieved by enriching food with various biologically active substances of herbal origin,so we formulated an herbal mixture that can be used as a supplement for a special type of bread(STB)to achieve better effects on postprandial glucose and insulin levels in patients with T2DM.AIM To compare organoleptic characteristics and effects of two types of bread on postprandial glucose and insulin levels in T2DM patients.METHODS This trial included 97 patients with T2DM.A parallel group of 16 healthy subjects was also investigated.All participants were given 50 g of rye bread and the same amount of a STB with an herbal mixture on 2 consecutive days.Postprandial blood glucose and insulin levels were compared at the 30^(th),60^(th),90^(th) and 120th min.A questionnaire was used for subjective estimation of the organoleptic and satiety features of the two types of bread.RESULTS Compared to patients who consumed rye bread,significantly lower postprandial blood glucose and insulin concentrations were found in T2DM patients who consumed STB.No relevant differences were found among the healthy subjects.Subjectively estimated organoleptic and satiety characteristics are better for STB than for rye bread.CONCLUSION STB have better effects than rye bread on postprandial glucoregulation in T2DM patients.Subjectively estimated organoleptic and satiety characteristics are better for STB than for rye bread.Therefore,STB can be recommended for nutrition in T2DM patients.
文摘This is the only report demonstrating innovative ancient whole grain gluten-free (no yeast or chemicals) products. Ancient whole grain gluten-free flatbreads were prepared with quinoa, teff, amaranth and buckwheat flours. Dough formulations contained flour, salt and water. Ingredients were mixed for 5 min using table top Kitchen Aid mixer at stir setting 1. Dough was equilibrated for 30 min. 65 g of dough was placed between two sheets of nonstick parchment paper and pressed to 17 cm round flatbreads in a Tortilla Chapatti Press. Each flatbread was cooked for two minutes (one minute each side) in using Flatbread Maker. Taste panels of 64 inhouse volunteers determined that Taste/Flavor of quinoa, teff and amaranth flatbreads were similar and significantly (P ≤ 0.05) better than those for buckwheat flatbread. The taste panel determined ancient whole grain gluten-free flatbreads had acceptance of quinoa 84%, teff 72%, amaranth 66% and buckwheat 38%. Each ancient whole grain gluten-free flatbread contained 25 - 30 g whole grain and 4 - 5 g protein. Quinoa, teff and amaranth one flatbread contained 2 - 3 g dietary fiber, whereas buckwheat flatbread contained 8 g dietary fiber. Consuming two whole grain gluten-free flatbreads with two meals (total = 4) would give 4 - 32 g of dietary fiber. The USDA food guide recom mends that at least 1/2 of all the grains eaten should be whole grains. The FDA allows food Health Claim labels for food containing 51% whole gains and 11 g of dietary fiber. The gluten sensitive individuals would enjoy tasty, health promoting, ancient whole grain easy to make flatbreads. These recipes offer consumers additional nutritious gluten-free choices and would lead to in crease in whole grain consumption.
文摘Objective:Seawater leakage in Al-Jabal Al-Akhdar East Libya's coastal areas is one of the most biggest obstacles to farmers obtaining a highly productive crop.As a result,the experiment was conducted in a laboratory to find out the impact of irrigation with seawater on the salt tolerance of Acsad Bread wheat genotypes.Method:Ten genotypes(1398,1492,1514,1522,1524,1536,1538,1544,1550,and 1562),obtained from the Arab Center for the Studies of Arid Zones and Dry Lands Acsad,were used in the study,10 seeds of each genotype with three repetitions were germinated under four seawater concentrations(10,20,30 and 40%).Results:The results showed that there were highly significant(P≤0.05)differences in the genotypes’response to all salinity concentrations,Which led to decreasing germination percentage,delaying the average germination time,and decreasing radical/plumule length and seedling fresh/dry weight compared with a control.As noted genotypes(1524,1522 and 1514)were able to germinate in all concentrations of seawater,and gave the best average for all the studied traits.Also,the study indicated that a concentration of seawater of 40%was the most toxic for all wheat genotypes.The results of this study categorize the wheat genotypes into tolerant genotypes(1524,1522 and 1514),moderate tolerant(1492,1536),and sensitive(1398,1538,1544,1550 and 1562).Conclusion:The results concluded that the possibility of wheat crops agriculture into tolerant in Libyan coastal locations in which seawater concentration did not exceed 30%.

文摘Staling is an important issue that Chinese steamed bread(CSB)may encounter during storage,which significantly affects their taste,flavor,and nutritional value.The monitoring technology for rapid aging is particularly important to effectively control the aging process of CSB,reduce quality deterioration,and promote the industrial production of CSB.Raman spectroscopy has been widely used in the study of food structure and properties due to its non-destructive and high-sensitivity characteristics,particularly demonstrating unique advantages in the analysis of starch structure.This study explored the possibility of analyzing the staling of CSB using Raman spectroscopy based on hardness and moisture content.Analysis of the correlation between the hardness of CSB and the full width at half maximum(FWHM)at 480 cm^(−1)during storage was conducted,and a significant positive correlation between them was found,with R^(2)above 0.8.Besides,nine characteristic peaks of CSB samples related to starch were selected for analysis.As the moisture content of CSB decreased,the peak intensities and areas of showed an upward trend during storage,with the best correlation coefficient above 0.8 revealed by linear regression analysis.Therefore,Raman spectra could be used as a potential method for the fast prediction of CSB staling.
文摘AIM:To describe the cardiovascular disease(CVD)risk factors in a population of children with celiac disease(CD)on a gluten-free diet(GFD).METHODS:This cross-sectional multicenter study was performed at Schneider Children’s Medical Center of Israel(Petach Tiqva,Israel),and San Paolo Hospital(Milan,Italy).We enrolled 114 CD children in serologic remission,who were on a GFD for at least one year.At enrollment,anthropometric measurements,blood lipids and glucose were assessed,and compared to values at diagnosis.The homeostasis model assessment-estimated insulin resistance was calculated as a measure of insulin resistance.RESULTS:Three or more concomitant CVD risk factors[body mass index,waist circumference,low density lipoprotein(LDL)cholesterol,triglycerides,blood pressure and insulin resistance]were identified in 14%of CD subjects on a GFD.The most common CVD risk factors were high fasting triglycerides(34.8%),elevated blood pressure(29.4%),and high concentrations of calculated LDL cholesterol(24.1%).On a GFD,four children(3.5%)had insulin resistance.Fasting insulin and HOMA-IR were significantly higher in the Italian cohort compared to the Israeli cohort(P<0.001).Children on a GFD had an increased prevalence of borderline LDL cholesterol(24%)when compared to values(10%)at diagnosis(P=0.090).Trends towards increases in overweight(from 8.8%to 11.5%)and obesity(from 5.3%to 8.8%)were seen on a GFD.CONCLUSION:This report of insulin resistance and CVD risk factors in celiac children highlights the importance of CVD screening,and the need for dietary counseling targeting CVD prevention.
文摘Zein,a class of alcohol-soluble prolamines in maize endosperm,is mainly composed of α-zein,β-zein,andγ-zein.It has been recognized as a structural protein for various gluten-free systems since it can form glutenlike viscoelastic network.The formation of viscoelastic zein network can make up for the structural defect of gluten-free doughs caused by the lack of gluten.To make the most of structural functionality of zein in glutenfree foods,it is important to clearly elucidate the fundamental properties of zein network.In this article,these properties have been discussed,analyzed and summarized from the relationship between protein network and structural functionality of zein,the feature and formation mechanism of zein network,factors affecting zein network and the applications of zein network in improving the quality of gluten-free food.In addition,this article also looks forward to potential research areas on zein network.
文摘Celiac disease is a genetically-determined chronic inflammatory intestinal disease induced by gluten in wheat,barley,rye etc.Celiac disease affects approximately one percent of people in the world and strict gluten-free diet(GFD)for a lifetime is the only available treatment.As gluten-free products available in the market are known to have low nutritional quality as well as are more expensive than gluten-containing food products,there is a strong need to develop gluten-free products that are nutritionally complete as well as economical.This review focuses on the special considerations during developing gluten-free products viz.,finding an alternate non-gluten source,ensuring nutrition and sensory quality characteristics,compliance with the regulatory guidelines,economics and product.
文摘AIM:To investigate all patients referred to our center with non-responsive celiac disease (NRCD),to establish a cause for their continued symptoms.METHODS:We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period.These individuals were investigated to establish the eitiology of their continued symptoms.The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement.They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion.A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible.Colonoscopy,lactulose hydrogen breath testing,pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted.Their clinical progress was followed over a minimum of 2 years.RESULTS:One hundred and twelve consecutive patients were referred with NRCD.Twelve were found not to have celiac disease (CD).Of the remaining 100 patients,45% were not adequately adhering to a strict gluten-free diet,with 24 (53%) found to be inadvertently ingesting gluten,and 21 (47%) admitting noncompliance.Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%.Refractory CD was diagnosed in 9%.Three of these were diagnosed with intestinal lymphoma.After 2 years,78 patients remained well,eight had continuing symptoms,and four had died.CONCLUSION:In individuals with NRCD,a remediable cause can be found in 90%:with continued gluten ingestion as the leading cause.We propose an algorithm for investigation.
文摘Celiac Disease (CD) is an inherited, autoimmune disorder in which proteins from the grains wheat, rye and barley (collectively called gluten) damage the small intestine. The only treatment for CD is a strict, lifelong gluten-free diet. With a prevalence rate of about one in 100-133 people worldwide. Celiac disease is wide-spread across the globe. Unlike traditional allergies, which cause immediate reactions, gluten sensitivity is harder to pin down since it manifests gradually and in various forms like headaches, stomach cramps, bloating, anxiety, and depression. Due to complicated diagnosis procedure and lack of awareness, many cases are either misdiagnosed or not at all diagnosed in India and USA. In spite of high growth, gluten-free foods are facing problems to grain ground in Asian market, due to high price, lack of awareness about the products, large number of un-diagnosed cases and inefficient value chain for gluten-free products. One of the major issues in India and USA is very high prices of gluten-free foods as compared to regular food products. Globally, the market potential of gluten free products is estimated to be USD 4639.13 Million and USD 7594.43 Million in 2015 and 2020 respectively. The global gluten free food market is projected to grow with a CAGR between 9 percent and 10.2 percent during 2016-2022. The study on consumer preference of gluten-free foods would enable manufacturers of gluten-free foods to understand the current and evolving expectations of consumers and to design the products according. Study of two countries i.e., India and USA would enable manufacturers to understand the difference in choices and preferences related to gluten-free foods for both the nations. This study would help manufacturers of alternative wheat product to form the concrete marketing and product development strategy based on recent consumer behavior trends.
文摘Gluten-free bakery products are produced for people suffering from celiac disease due to sensitivity to gluten. So, the aim of this work was to study the effect of partial substitution of rice flour at 20%, 30% and 40% with sorghum and germinated chickpea flours on rheological, physical, sensory properties and staling rate of prepared gluten-free cake. Obtained results showed that germinated chickpea flour had the highest contents of crude protein (23.62%), lipids (4.89%) and crude fibers (5.76%) as compared to other grain flours. Gradual increase in gelatinization temperature and decrease in maximum viscosity and setback were fond of cake batters with increasing the substituting levels of rice flour from 20% to 40% with sorghum or germinated chickpea flours in comparison to rice flour batter. No significant difference was observed in specific volume between rice cake and cake containing 20% of germinated chickpea and sorghum flours which given 2.71, 2.62 and 2.56 cm3/g, respectively. Data also revealed that gluten-free cake lightness (L*) and total intensity significantly increased with 40% of sorghum flour followed by 30 and 20% of sorghum flour. Substitution of 40% rice flour with germinated chickpea flour resulted in significant high in redness (a*), yellowness (b*) and chroma of gluten-free cake being 11.95, 33.72 and 35.77, respectively followed by substituted levels 30% and 20% which attributed to their natural yellow pigments compared with other investigated samples. Overall acceptability of gluten-free cakes was improved after adding 20, 30% of sorghum flour and 20% of germinated chickpea flour which being 90.7, 88.6 and 87.5, respectively compared to rice flour cake (88.4). Rice flour cake was more freshness than wheat flour cake and other treatments during storage duration. After 6 days, rice cake had significant high freshness (306.2%) followed by gluten-free cake samples with 20% of sorghum or germinated chickpea flours which given 294.5% and 289.4%, respectively. Generally, it could be concluded that the quality and nutritional properties of gluten-free rice cakes could be improved when using 20%, 30% of sorghum flour and 20% of germinated chickpea flour as substitution levels of rice flour.
文摘In this study, the effect of lupin flour (LF) and whole buckwheat flour (BF) on the physical properties of gluten-free cake was studied. LF up to 40% and BF flour up to 20% level were partially replaced with corn starch and rice flour mix in the gluten free cake recipe. Cake dough properties (specific gravity and pH), cake properties (weight, volume, symmetry and uniformity index, hardness), crust and crumb color values were investigated. High addition levels of LF decreased the pH values of the dough. Compared to control, volume index of the cakes improved with BF at 5% addition level or LF up to 20% level. While minimum level of the LF/BF gave softer cake texture, high substitution levels of LF (30%-40%) and BF (15%-20%) had detrimental effect on softness of the samples. All addition level of the LF increased the darkness and yellowness of the cake's crust and crumb, whereas BF above 5% level decreased lightness and yellowness of the samples. The high levels of LF (30%-40%) and BF (15%-20%) had reducing effect all physical properties of gluten-free cake samples.

文摘Chestnut is a high nutritional value food that has been widely used as a tonic in traditional Chinese medicine.As an emerging functional food ingredient,Chinese chestnuts are rich in a range of bioactive nutrients such as starch,dietary fiber,fat,protein,trace metal element and vitamins A,B,C,D and other nutrients.In our study,Chinese chestnut powder(CCP)were added into bread formulation at 2%-6%levels(based on flour weight)to produce fresh bread with enhanced anti-staling characteristics and starch digestion inhibitory ability.The texture properties,retrogradation enthalpy,water distribution,and estimated glycemic index(eGI)of wheat bread containing CCP as a functional additive were also investigated.The results showed that incorporation of CCP apparently affected bread texture,resulting in increased hardness,as well as decreased the specific volume of wheat bread.These influences were generally proportional to the amount of CCP used.It was found that adding too much CCP resulted in a dark red color,showing increased significantly higher total color difference(ΔE)and L values.Conversely,addition of CCP significantly reduced starch digestion rate and digestion extent in bread,and the reduction degree was positively related to the amount of CCP applied.The greatest reduction in eGI value from 79.40(control)to 75.02(6%CPP bread)was observed.Meanwhile,the content of resistant starch of 6%CPP bread was about 1.36 times higher than that of control bread.CCP also reduced crumb water loss and drove the water shift from the bound to the mobile state after stored for 7 days.The retrogradation enthalpy analyses further confirmed that CCP inhibited starch retrogradation and recrystallization.These results suggested that Chinese chestnut powder could be incorporated into fresh bread to provide health functions,such as lowering potential glycaemic response and improving anti-staling characteristics of bread.
文摘Selective Ig M deficiency(s IGMD)is very rare;it may be associated with celiac disease(CD).We present the case of an 18-year-old man with s IGMD masking seronegative CD.Symptoms included abdominal pain,diarrhea and weight loss.Laboratory tests showed reduced Ig M,DQ2-HLA and negative anti-transglutaminase.Villous atrophy and diffuse immature lymphocytes were observed at histology.Tissue transglutaminase m RNA mucosal levels showed a 6-fold increase.The patient was treated with a gluten-free diet(GFD)and six months later the symptoms had disappeared,the villous architecture was restored and mucosal tissue transglutaminase m RNA was comparable to that of healthy subjects.After 1 year of GFD,a complete restoration of normal Ig M values was observed and duodenal biopsy showed a reduction of immature lymphocytes and normal appearance of mature immune cells.
文摘This report demonstrates innovative ancient whole grains, gluten-free, egg-free pasta (no chemicals added) made using a kitchen counter-top appliance. Whole grain, fusilli pasta was prepared with teff, buckwheat, quinoa and amaranth flours. These ancient grains are called “Super Foods” due to their ideal essential amino acids and mineral profiles. Dough formulations contained 95% whole grain flour and 5% guar gum. Taste panels of 62 in-house volunteers judged amaranth pasta significantly (p ≤ 0.05) higher in color/appearance than other pastas tested. Odor/aroma of buckwheat pasta and texture/mouth-feel of teff pasta were significantly better than quinoa and amaranth pasta. Acceptance and taste/flavor of teff and buckwheat pasta were similar and significantly higher than quinoa and amaranth pasta (teff = buckwheat > quinoa > amaranth). The USDA food guide recommends that at least 1/2 of all the grains eaten should be whole grains. The FDA allows food Health Claim labels for food containing 51% whole gains and 11 g of dietary fiber per serving. Novel health promoting whole grain, good source of protein, gluten-free, egg-free (no chemicals added) pasta had acceptance of teff 87%, buckwheat 82%, quinoa 61% and amaranth 15%. Amaranth pasta needs improvement in several sensory attributes by fortification, processing and/or use of other cultivars for the desired results. Ancient whole grain, gluten-free, egg-free pasta would increase whole grain consumption and offer a healthy option to vegetarians as well as to gluten sensitive individuals.
