Документ Expansion of the range of yeast-free bakery products made using fermented dairy products(2024) Zabroda, Аrtem; Godunko, Ievgen; Bilyk, Olena; Bondarenko, YuliiaTraditionally, biological methods are used to leaven dough semi-finished products in the production of bakery products. However, today consumers are increasingly including yeast-free bakery products in their diet. Given the growing demand for yeast-free bakery products, it is advisable to expand the range of products in this category. To ensure the formation of a developed crumb in yeast-free bakery products, chemical leavening agents are used in their production. Yeast-free bakery products were made using various fermented dairy products: ayran (2,0% fat), kefir (2,5% fat), bifidoyogurt (1,5% fat), and ryazhenka (4,0% fat). To determine the most effective fermented dairy product for the production of high-quality yeast-free bakery products, trial baking was conducted. Experimental dough samples were kneaded using two types of chemical leavening agents - sodium bicarbonate and ammonium carbonate. The dough was prepared using the straight dough method. The duration of dough resting after kneading was 20-30 minutes. The dough pieces were shaped into "okrayets" (small loaves): the dough was rolled to a thickness of 1,5 cm and the dough pieces were cut out with a cutter, placed on a sheet, and baked in a rack oven at +200-240°C for 16-18 minutes. The research results established that it is advisable to use ryazhenka in the production of yeast-free bakery products using fermented dairy products. At the same time, sodium bicarbonate should be included in the recipe to leaven the crumb. Such a product had the highest comprehensive quality index. Based on organoleptic and microbiological indicators, the product was found to have a shelf life of no more than 48 hours. To improve the taste and aromatic properties of the product, 3% malted barley extract and 4% white crystalline sugar were included in its composition. The developed yeast-free okrayets with ryazhenka was characterized by a higher content of bisulfate-binding substances, indicating an improved aroma of the product and a darker color of the crust and crumb. The developed product meets the body's needs for proteins by 31,5%, fats by 10,5%, carbohydrates by 49,0%, and dietary fiber by 18,3%.Документ Study of dough fermentation process with flax seeds(2023) Bondarenko, Yuliia; Andronovich, Galina; Kaprelyants, Leonid; Bilyk, Olena; Naumenko, OksanaThe article investigates the fermentation processes in wheat dough containing whole and crushed flax seeds in dry and soaked states. It was found that in the process of fermentation in samples with whole flax seeds in dry and moistened states, the amount of carbon dioxide released slightly increases compared to the control. In the samples with crushed flax seeds in dry form and with moistened crushed flax seeds, the total amount of carbon dioxide released is higher than in the control sample by 16.5 % and 19.0 %, respectively. In the sample with crushed flax seeds, the nature of the dynamics of carbon dioxide release differs from the control sample, namely, a one-stage fermentation is observed. At the same time, the peak of carbon dioxide emission was observed almost 30 minutes later than in the control sample. The use of moistened whole and crushed flaxseeds results in a slightly lower intensity of carbon dioxide emission compared to dry samples. Based on the analysis of the dynamics of carbon dioxide emission, it is recommended to reduce the duration of dough fermentation for the sample with whole flax seeds to 90 minutes, and for the samples with crushed seeds and soaked flax products to 60 minutes. It was found that the introduction of whole and crushed flax seeds in a moistened form slows down the rise of the dough due to the thickening of the dough system with water-soluble and insoluble flax dietary fiber, reducing fermentation and the formation of sugars in the dough system.Документ Studying the effect of milk processing products on the structural-mechanical properties of wheat flour dough(2021) Bilyk, Olena; Vasylchenko, Tetyana; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Piddubnyi, VolodymyrDry whey enriched with magnesium and manganese (DW) that contains protein in the amount of 13 %, and a whey protein concentrate (WPC) with a protein content of 65 %, have been chosen as functional bases in the production of complex baking improvers with a targeted effect. When developing a composition of the complex improver, the rational dosage of DW is 2 % by weight of flour, and that of WPC – 3 % by weight of flour. Adding DW and WPC during the kneading of wheat flour dough predetermines a decrease in its gluten content, by 4 % and 6.1 %, respectively, after 20 minutes of the dough rest, and by 7.5 and 10.7 % after two hours of the dough fermentation. This is due to the introduction of lactic acid with milk processing products, which peptizes proteins resulting in that the gluten proteins are partially converted into water-soluble ones. If DW and WPC are included in the dough formulation, there is an increase in the total amount of proteins in it, as well as a change in their fractional composition: the mass fraction of water-soluble and intermediate fractions of proteins increases while the amount of gluten proteins decreases. That confirms a decrease in the amount of gluten washed out from the dough with the addition of DW and WPC. Increasing the mass fraction of water-soluble proteins contributes to the intensification of the fermentation process through the additional nutrition of microflora with nitrogenous substances and an increase in the content of free water in the dough, which predetermines its thinning. It was established that despite the high water absorption capacity of DW and WPC, the water-absorbing ability of the dough that contains them decreases compared to control by 8.4 and 10.7 %, respectively. Studying the dough at the farinograph has shown that in the case of using DW, its stability is somewhat prolonged while in the case of WPC introduction the dough stability is extended by almost 10 minutes, which leads to prolonging the dough kneading. Along with this, in the case of using WPC, there is a rapid descent of the farinogram curve, which could lead to a strong weakening of the dough during fermentation and rest, even though that the thinning after 12 minutes is lower than that of control
