Документ The use of an enzyme preparation when using calcium acetate in wheat bread technology(2019) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Chernyushok, OlgaAn important problem of bakery is the prevention of the main causes of spoilage of bread, namely the development of microorganisms, which, under favorable conditions, become activated and lead to complete unsuitability of the product for consumption. The spores of bacteria of the group of potato sticks are quite resistant to thermal effects, they remain viable even at temperatures close to 130 °C, but are sensitive to an acidic environment. The use of calcium acetate in the recipe of wheat bread to carry out a booming effect on microorganisms will also affect the quality of products. To improve the quality of such products, it is advisable to use amylolytic enzymes to intensify the fermentation of the dough and oxidative additives to reduce its stickiness and spreading. The object of research in the work is dough made from wheat flour of the first grade, the formulation of which includes calcium acetate, the enzyme preparation Alphamalt V and ascorbic acid. It is established that from the point of view of influencing the quality of finished products, a rational dosage of calcium acetate is 0.3 % by weight of flour. The optimal dosage of the enzyme preparation Alphamalt V is 0.015 % by weight of flour and ascorbic acid – 0.006 %. It is proved that the introduction of this composition of food additives improves gas removal ability by 15...20 % compared with the control and products containing only calcium acetate. The positive effect of the use of an enzyme preparation of amylolytic action along with calcium acetate on the lifting force of yeast has been established. This helps to intensify the fermentation of the dough and increase the specific volume and porosity of wheat bread. It is established that the use of a composition of food additives positively affects the elastic-elastic properties of the dough: the spreading of the dough balls decreases and the gas-holding ability increases by 10...13 % compared with products from calcium acetate. This leads to an increase in the specific volume and shape stability of bread. Thanks to the developed composition of food additives, it is possible to use calcium acetate to inhibit potato sticks without losing the quality of the finished product.Документ Studying the effect of the integrated bread baking improver "Mineral freshness super" on consumer properties of wheat bread(2019) Bilyk, Olena; Bondarenko, Yuliia; Kochubei-Lytvynenko, Oksana; Halykova, Esma; Fain, AlbinaScientists from the National University of Food Technologies (Ukraine) developed the integrated bread baking improver "Mineral Freshness Super" whose formulation includes nutritional supplements with the GRAS status. The integrated bread baking improver is composed of a functional base, white pharmacopoeial clay, and an active part ‒ the enzymatic preparations Alphamalt VC 5000 and Novamil 1500MG, maltodextrin, sunflower-derived fat-free lecithin, apple pectin, dry wheat gluten and ascorbic acid. Technological efficiency has been proven to use the integrated bread baking improver "Mineral Freshness Super" in the amount of 1.5 % by weight of flour in order to slow the staling of wheat bread, baked according to the accelerated technology. We have determined regularities in the influence of the integrated bread baking improver "Mineral Freshness Super" on quality of wheat bread. It was established that introducing it to dough results in an increase in the relative volume of products, improves shape formation, porosity, and reduces the duration of fermentation by three times, specifically to 20 min. It has been proven that products with the addition of the integrated bread baking improver "Mineral Freshness Super" retain freshness better, which is confirmed by the increase in the overall deformation of crumb, by a smaller layer under the crust, and by fewer layers of air in the products' crumb. We have observed more accumulation of dextrins and bisulfite binding substances in products when using integrated bread baking improver "Mineral Freshness Super", indicating the inhibition of staling and improvement in consumer properties. Results of our study prove the expediency of using the integrated bread baking improver "Mineral Freshness Super" in the technology of wheat bread to prolong its freshness up to 72 h when storing unpacked.Документ Investigation of influence of inulin made from cycoria on structural-mechanical properties of wheat dough(2019) Bondarenko, Yuliia; Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Halykova, Esma; Fain, AlbinaBread made from wheat flour in chemical composition is not well balanced for vital ingredients. One of its drawbacks is that with a high content of carbohydrates in it there is little dietary fiber, therefore, it is promising to enrich it with inulin-compliant products. The inclusion of inulin made from chicory in the recipe of wheat bread to influence the formation of the rheological properties of the dough, which will affect the quality of the finished products. Therefore, the object of research in the work is the dough of wheat flour of the first grade, the recipe of which includes inulin made from chicory. During the research, inulin made from chicory «Cosucra» (Belgium) is used in the amount of 5, 10, 15 % by weight of flour. It is established that the addition of inulin leads to an increase in the elastic properties of the dough, especially with an increase in the dose of inulin by more than 10 %. Increasing the dose of inulin up to 15 % and more along with an increase in the elastic characteristics reduces the dough elasticity, causing a significant deterioration in the volume of products. It is proven that a decrease in the specific volume of products and an increase in the elastic characteristics of the crumb are the limiting factors of using inulin products in the formulation of more than 10 % by weight of the flour. Use in the formulation of inulin bread in the amount of 10 and 15 % by weight of flour due to the increase in the elastic properties of the dough leads to a significant deterioration in the volume of products. The taste and aroma of inulin products are inherent in wheat bread. Due to the inclusion of inulin wheat bread in the recipe, the products acquire prebiotic properties, however, the effectiveness of using inulin to improve the quality of finished products is possible with dosing 5 % by weight of flour. For greater enrichment of bakery products with dietary fiber, it is possible to use the dosage of inulin 10 % by weight of flour, but to apply technological measures to improve the quality of products.Документ Developing an improver of targeted action for the prolonged freshness of bread made from wheat flour(2020) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Vasylchenko, Tetyana; Pukhliak, AnastasiiaThe development of a complex bakery improver "Freshness CDP SUPER" (Ukraine) to slow down the staling of products developed for accelerated technologies is urgent. It contains nutritional supplements with GRAS status. Whey protein concentrate "CDP-UV-65" was chosen as a functional basis. The active part contains the enzyme preparation Novamil 1500MG, maltodextrin, defatted sunflower lecithin, carboxymethyl cellulose, apple pectin, dry wheat gluten and ascorbic acid. It is proved that with rational dosage of the developed complex bakery improver in the amount of 1.5% to the flour mass, the bread production process is reduced by 180 minutes. It has been established that the bread "Milk Freshness", the recipe of which includes the developed improver, is characterized by a higher specific volume by 10.1% in comparison with the control, porosity, and better shape stability of hearth products. It has been proven that products with the addition of the Freshness CDP SUPER complex bakery improver retain freshness longer, which is confirmed by a 47% greater total crumb deformation compared to the control. The inhibition of staling in bread "Milk Freshness" occurs due to the accumulation of dextrin by 27.1% compared with the control. Thus, the total content of dextrins in wheat bread is 1.918% to DS, and in Milk Freshness bread - 2.438% to DS.The research results prove the expediency of using the complex bakery improver "Freshness CDP SUPER" in the technology of wheat bread in order to extend the preservation period of its freshness up to 72 hours in unpackaged form.
