A Multifunctional Bread Rich in Beta Glucans and Low in Starch Improves Metabolic Control in Type 2 Diabetes: A Controlled Trial
Abstract: Design: Functional foods may be useful for people with diabetes. The soluble fibers beta
glucans can modify starch digestion and improve postprandial glucose response. We analyzed
the metabolic effects of a specifically designed \u2018functional\u2019 bread, low in starch, rich in fibers
(7 g/100 g), with a beta glucan/starch ratio of (7.6:100, g/g), in people with type 2 diabetes
mellitus. Methods: Clinical and metabolic data from two groups of age-, sex- and glycated
hemoglobin-matched diabetic subjects, taking either the functional bread or regular white bread,
over a roughly six-month observation period, were retrieved. Results: Bread intake did not change
during the trial. The functional bread reduced glycated hemoglobin by ~0.5% (absolute units) vs.
pre-treatment values (p = 0.028), and by ~0.6% vs. the control group (p = 0.027). Post-prandial and
mean plasma glucose was decreased in the treatment group too. Body weight, blood pressure and
plasma lipids did not change. The acceptance of the functional bread was good in the majority
of subjects, except for taste. Conclusions: A starch-restricted, fiber-rich functional bread, with an
increased beta glucan/starch ratio, improved long term metabolic control, and may be indicated in
the dietary treatment of type 2 diabetes
Functional Ingredients and Food Choice: Results from a Choice Experiment
In this paper we present the results of a Choice Experiment (CE) conducted to examine how the inclusion of an attribute for a functional ingredient affects consumer food choice. Specifically, we examine consumer attitudes towards bread and the inclusion of a functional ingredient (eg, inulin), which can be added to bread to increase the quantity and the effectiveness of fibre in the final product A novel feature of the design of this CE was the use of Means-End-Chain analysis via semi-structured interviews to reveal key attributes to be included in the CE. In addition, the CE included the Dutch Eating Behaviour Questionnaire (DEBQ) so as to collect information on all participants underlying eating behaviours. Preliminary analysis of the data reveals that bread type determines choice, and that the inclusion of a functional ingredient yielded relatively small measures of value. Also, the use of a Latent Class Model reveals that there are differences in willingness-to-pay (WTP) between groups of respondents and that group membership can be partly explained by the DEBQ information. The public health implications of these findings are discussed.Functional Food, Bread, Choice Experiment, Food Consumption/Nutrition/Food Safety, I10, Q10, R22,
Wheat bread with dairy products - Technology, nutritional and sensory properties
Featured Application: Bakery industry, as nutritional and functional breads, with a considerable
contribution to balance the daily diet for children and seniors in terms of proteins and mineralsAs the relation between diet and health became a priority for the consumers, the development
of healthy foods enriched with functional ingredients increased substantially. Dairy products represent
an alternative for new products and can be used to enhance the functional and nutritional value
of bakery products. The addition of yoghurt and curd cheese to wheat bread was studied, and the
impact on the dough rheology, microstructure, bread quality, and sensory properties were evaluated.
Dairy product additions from 10 to 50 g and higher levels up to 70 g of yoghurt and 83 g of curd
cheese were tested. Replacements were performed on wheat flour basis and water absorption. It was
observed that the yoghurt additions had a positive impact on the rheology characteristics of the
dough. For curd cheese additions, the best dough evaluated on extension was the 30 g of wheat flour
formulation. In both cases, the microstructure analysis supported the results obtained for doughs and
breads. These breads showed a significant improvement on nutrition profile, which is important to
balance the daily diet in terms of major and trace minerals and is important for health-enhancing and
maintenance. Good sensorial acceptability for breads with 50 g of yoghurt and 30 g of curd cheese
was obtainedinfo:eu-repo/semantics/publishedVersio
Physical mapping integrated with syntenic analysis to characterize the gene space of the long arm of wheat chromosome 1A
Background: Bread wheat (Triticum aestivum L.) is one of the most important crops worldwide and its production faces pressing challenges, the solution of which demands genome information. However, the large, highly repetitive hexaploid wheat genome has been considered intractable to standard sequencing approaches. Therefore the International Wheat Genome Sequencing Consortium (IWGSC) proposes to map and sequence the genome on a chromosome-by-chromosome basis.
Methodology/Principal Findings: We have constructed a physical map of the long arm of bread wheat chromosome 1A using chromosome-specific BAC libraries by High Information Content Fingerprinting (HICF). Two alternative methods (FPC and LTC) were used to assemble the fingerprints into a high-resolution physical map of the chromosome arm. A total of 365 molecular markers were added to the map, in addition to 1122 putative unique transcripts that were identified by microarray hybridization. The final map consists of 1180 FPC based or 583 LTC based contigs. Conclusions/Significance: The physical map presented here marks an important step forward in mapping of hexaploid bread wheat. The map is orders of magnitude more detailed than previously available maps of this chromosome, and the assignment of over a thousand putative expressed gene sequences to specific map locations will greatly assist future functional studies. This map will be an essential tool for future sequencing of and positional cloning within chromosome 1A
Marketing Studies Of Consumption Preferences At Developing Dietary Products
Results of marketing studies of consumption motivations and preferences at choosing bread for special dietary consumption are presented. It has been established, that 18 % of questioned give advantage to bread with a decreased amount of carbohydrates; 17 % of respondents consume bread without gluten; 13 % give preference to products, including nutrients; 10 % by iodine-containing bread; 7 % and 6 % of questioned give preference to bread with a content of soya and entersorbents. It has been established, that bread with a content of carotene and lecithin is not widely demanded among respondents as 3 % for each one. Studies of % of preferences by flour types in the bread composition allowed to make conclusions that 19 and 17 % of respondents give preference to corn and buckwheat flour due to a higher content of healthy substances, it is also an important advantage that these flour types don't contain cellulose complexes, present in the composition of wheat and barley flour, preferred by 14 and 11 % of questioned, respectively. It has been established by the experimental way, that 20 % of questioned persons feel a lack of bread with an increased content of protein at the market. 15, 12 and 10 % of respondents want widening the assortment of bread with an increased content of macroelements, vitamins and microelements. 13 and 10 % of questioned feel a lack at the market in such physiological-functional ingredients as polyunsaturated fatty acids and products of gluten-free flour. 8 % of respondents want to see in the retail network products with a content of dietary fiber and antioxidants. 9 % feel a lack of bread with a content of probiotics, 3 % of oligosaccharides. Based on the obtained results, there have been determined consumption advantages: a modern consumer gives preference to products with the improved content, usual organoleptic parameters, long storage term, low price. He/she is guided by the following criteria at buying bread: food value, caloric value, prophylactic properties
Investigation of the Cinnamon Influence on the Wheat Bread Quality Enriched with Flax Seeds Oil Meal
The materials of the article are studies that are conducted with the aim of expanding the use of non-traditional raw materials for functional purposes in the technology of bakery products. Research is conducted to determine the effect of spiciness cinnamon on the quality of semi-finished products and finished bakery products from wheat flour enriched with flax seeds oil meal.To improve the quality of wheat bread, enriched with flax seeds oil meal, and expand the assortment of bakery products with health properties, the authors propose to use spice cinnamon in the formula of wheat bread in an amount of up to 2 % of the weight of flour. The taste and aroma of these products is characteristic of wheat bread with a pleasant cinnamon flavor. Dosage of cinnamon to 4 % of the flour mass also provides good consumer characteristics of products, however, more pronounced flavor and flavor of cinnamon can limit the circle of consumers of such products. The use of 6 % of cinnamon in the recipe of products leads to a significant deterioration in the volume of products and provides them with too intense flavor. Determination of the content of bisulphite-binding substances in the crumb and crust of products is confirmed by improvements in the fragrance of products with the addition of cinnamon.It has been established that the cinnamon in dough leads to an increase in the elastic properties of gluten, and the more, the more it is added. Along with this, it is noted that cinnamon leads to a decrease in the fermentation intensity of the dough. This is probably due to the active antibacterial properties of cinnamon, which suppress the yeast fermentation activity. These factors and cause the deterioration of the volume of finished products in the case of dosing cinnamon in an amount of 4 % or more.It has been proved that on the indicators of crumbling and deformation of the crumb, products with added cinnamon retain their freshness similarly to the control one. However, it is noted that the introduction of cinnamon reduces the amount of mold of microflora in products
Research Into Technological Indicators of a Rye-wheat Dough Semi-finished Product with the Addition of the Polyfunctional Food Supplement "Magnetofооd"
We studied influence of the polyfunctional food supplement "Magnetofооd" on the technological parameters of rye-wheat dough semi-finished product and the finished product. A positive effect of the supplement "Magnetofооd" on the technological parameters of dough and the bread baked using it, is shown. It was established that adding the food supplement "Magnetofооd" in the amount of 0.15 % of the weight of flour reduces dough fermentation time by 13.0 on average %. The introduction of the food supplement "Magnetofооd" also increases the yield of a dough semi-finished product by 2.9 % on average and improves the yield of the finished product by 3.45 % on average. It was revealed that the multifunctional food supplement "Magnetofооd" enhances the quality of rye-wheat dough semi-finished product and the finished product due to its capacity of moisture retention and the inhibition of hydrolysis processes of the basic ingredients of dough.The obtained experimental data could be used to develop a technology of rye-wheat bread, enriched with the polyfunctional food supplement "Magnetofооd"
Delayed gastric emptying and reduced postprandial small bowel water content of equicaloric whole meal bread versus rice meals in healthy subjects: novel MRI insights
BACKGROUND/OBJECTIVES: Postprandial bloating is a common symptom in patients with functional gastrointestinal (GI) diseases. Whole meal bread (WMB) often aggravates such symptoms though the mechanisms are unclear. We used magnetic resonance imaging (MRI) to monitor the intragastric fate of a WMB meal (11% bran) compared to a rice pudding (RP) meal.
SUBJECTS/METHODS: 12 healthy volunteers completed this randomised crossover study. They fasted overnight and after an initial MRI scan consumed a glass of orange juice with a 2267 kJ WMB or an equicaloric RP meal. Subjects underwent serial MRI scans every 45 min up to 270 min to assess gastric volumes and small bowel water content and completed a GI symptom questionnaire.
RESULTS: The MRI intragastric appearance of the two meals was markedly different. The WMB meal formed a homogeneous dark bolus with brighter liquid signal surrounding it. The RP meal separated into an upper, liquid layer and a lower particulate layer allowing more rapid emptying of the liquid compared to solid phase (sieving). The WMB meal had longer gastric half emptying times (132±8 min) compared to the RP meal (104±7 min), P<0.008. The WMB meal was associated with markedly reduced MRI-visible small bowel free mobile water content compared to the RP meal, P<0.0001.
CONCLUSIONS: WMB bread forms a homogeneous bolus in the stomach which inhibits gastric sieving and hence empties slower than the equicaloric rice meal. These properties may explain why wheat causes postprandial bloating and could be exploited to design foods which prolong satiation
Viability of some probiotic coatings in bread and its effect on the crust mechanical properties
9 pages, 4 figures, 3 tablesThe objective of this study was to obtain functional bread combining the microencapsulation of Lactobacillus acidophilus and starch based coatings. Different probiotic coatings (dispersed or multilayer) were applied onto the surface of partially baked breads. In all treatments, microencapsulated L.acidophilus survived after baking and storage time, although reduction was higher in the sandwich treatment (starch solution/sprayed microcapsules/starch solution). Despite coatings significantly affected the physicochemical properties of the crust, increasing water activity and reducing the failure force, the sensory evaluation revealed a good acceptability of the functional breads. Scanning electron microscopy revealed the presence of scattered microcapsules onto the bread crust, being highly covered in the sandwich coating. Therefore, L.acidophilus included in microcapsules can be incorporated to bread surface through edible coatings, leading functional bread with similar characteristics to common bread, but with additional healthy benefits.Authors acknowledge the financial support of Spanish Ministry of Economy and Sustainability (Project AGL2011-23802) and the Consejo Superior de Investigaciones Científicas (CSIC).
