Investigation of the Water-retaining Capacity of the Carbohydrate Complex of Rye-wheat Dough with Addition of Polyfunctional Food Supplement “Magnetofооd”

Today in Ukraine the share of low-quality bakery products is near 20–25 %, because they often don\u27t correspond to quality standards and sanitary norms, because of being produced of flour with low bakery properties. That is why new raw material sources, functional ingredients and so on are searched for in bread technologies. For using new raw material and food supplement types, it is necessary to know their functional-technological properties (FTP) that allows to prognosticate the behavior of powder-like raw materials and food supplements in food masses at technological processing and storage of ready products.The water-retaining capacity (WRC) is one of main functional-technological parameters of carbohydrate-containing raw materials, because it favors the outcome, structural-mechanical properties and quality characteristics of ready products.The authors introduced “Magnetofood” polyfunctional food supplement for increasing WRC of rye-wheat dough. For grounding the mechanism of forming supramolecular groups in carbohydrate food systems: Magnetofood-polysacharide-water, there was studied the influence of “Magnetofood” food supplement on processes of hydration, swelling and water-retention by rye-wheat starch and rye-wheat flour.It was established, that introduction of “Magnetofood” food supplement in rye-wheat starch and flour in amounts: 0,10; 0,15; 0,20 % to the mass of starch or flour increases swelling and water-retaining capacity (WRC) of starch and flour: swelling in 1,3–1,5 and 1,5–2,25 times, respectively; WRC in 1,10–1,15 and 1,1–1,3 times, respectively.The rational dose of “Magnetofood” food supplement – 0,15 % to the mass of dry raw material was experimentally set. There was studied the influence of “Magnetofood” food supplement on rheological properties of water suspensions of rye-wheat starch and flour at different temperatures and different speeds of shift.It was established, that adding “Magnetofood” in amount 0,15 % favors increasing the effective viscosity of suspensions of experimental samples of starch and flour at temperatures: (23±2) ºС and (40±2) ºС comparing with control samples in average by 29,0 % – for starch and by 22,0 % – for flour at 23 °С and by 16,0 % – for starch and by 10,0 % – for flour at 40 °С.There was studied the dynamics of changing viscosity of colloid solutions of starch and flour, enriched with “Magnetofood” in amount 0,15 % to the mass of dry raw material in the keeping process at different temperatures and shift speed 9 s-1.There was established the increase of viscosity of suspensions of rye-wheat starch and flour in the process of infusion (especially at adding “Magnetofood”) that is connected with continuing hydration and swelling process.It was demonstrated, that the temperature increase of the colloid system from (23±20) ° С to (40±2) °С favors the increase of its viscosity – both at the initial moment and in infusion process during 30 min in average by 20,0–25,0 % at the expanse of the aforesaid processes. Moreover, adding “Magnetofood” accelerates and intensifies the processes of swelling and hydration of experimental samples of rye-wheat starch and flour comparing with control ones.The received experimental data may be used at elaborating the technology of rye-wheat bread, enriched with “Magnetofood” food supplement; and also at elaborating innovative technologies of carbohydrate food systems.The results of this study may be used at elaborating recipes and technologies of carbohydrate-containing food products for increasing their viscosity, water-retaining and stabilizing capacities

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"

Lipid distress-syndrome and prospects of its correction by statines

Endothelial dysfunction in peritonitis: The formed concept of lipid distress syndrome (LDS) allows us to develop a working hypothesis on the key role of endothelial dysfunction in the aggressive development of atherosclerosis. The role of vascular endothelium in atherosclerosis: The process of NO production from L-arginine through eNOS involving tetrahydrobiopterin (BH4) is discussed. With the degradation of BH4 along the free radical path, an "eNOS uncouplation" (uncoupled eNOS). The clinical role of statins: Statins manifests itself by inhibiting the enzyme 3-hydroxy- 3-methylglutaryl-coenzyme A (HMG-CoA reductase). Many large, randomized clinical trials have shown that lipid-lowering strategies that include statins have an anti-atherogenic potentia

SEQUENTIAL EXTRACTION OF SUBSTANCES WITH KNOWN Au SPECIATION – AN EXPERIMENTAL DATA

A study has been conducted on the features of distriburion of Au among the fractions of a 7-step sequential extraction procedure using model substances that are similar in composition to natural organic matter from the dispersion train of sulfide tailings. Use has been made of model substances with known Au speciations: bulk native gold, nanoscale native gold, Au-containing pyrite, humic acids, and Fe(III) oxides/hydroxides, which served as the basis for preparing mixtures with low-Au filler substances (quartz, limestone, humic acids, Fe(III) oxides/hydroxides).It has been stated that several Au species are leached in one fraction during sequential extraction. Nanoscale Au0 and gold bound to the organic matter are leached together in easily oxidizable (organic) fraction; gold bound to Fe(III) compounds and Au complexes chemisorbed on the surface of other minerals (sulfides, aluminosilicates) are leached in reducible (hydroxides) fraction; "invisible" gold in sulfides, nanoscale Au0 and, partially, >1 μm-seized bulk Au0 are leached in hardly oxidizable (sulfidic) fraction. Bulk native gold is leached predominantly in residual fraction. Mobile species are Au bound to water-soluble organic compounds and complexes of ionic Au desorbed from the surface of minerals

Enabling magnetic resonance imaging of hollow-core microstructured optical fibers via nanocomposite coating

Optical fibers are widely used in bioimaging systems as flexible endoscopes capable of low-invasive penetration inside hollow tissue cavities. Here, we report on the technique which allows magnetic resonance imaging (MRI) of hollow-core microstructured fibers (HC-MFs), paving the way for combing MRI and optical bioimaging. Our approach is based on Layer-by-Layer assembly of oppositely charged polyelectrolytes and magnetite nanoparticles on the inner core surface of HC-MFs. Incorporation of magnetite nanoparticles into polyelectrolyte layers renders HC-MFs visible for MRI and induces the red-shift in their transmission spectra. Specifically, the transmission shifts up to 60 nm have been revealed for the several-layers composite coating along with the high-quality contrast of HC-MFs in MRI scans. Our results shed light on marrying fiber-based endoscopy with MRI that opens novel possibilities for minimally invasive clinical diagnostics and surgical procedures in vivo.Comment: 11 pages, 6 figure
