    Determining the effect of a multicomponent mixture on the quality of pastry products containing a mixture of germinated grains
    (2021) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Burchenko, Liudmila; Fain, Albina
    A bun with a mixture of germinated cereals of wheat, oats, barley, and corn is an innovative product rich in dietary fiber, replaceable and essential amino acids, micro and macro elements, vitamins. In the process of germination, grains accumulate a large number of amylolytic and proteolytic enzymes, which worsen the structural and mechanical properties of the crumb of pastry products, as a result of which it becomes sticky and wrinkled. The experimental study reported in this work aimed to improve the organoleptic indicators and prolong the freshness of pastry products whose formulation includes a mixture of germinated grains. The expediency has been proven of using the polycomponent mixture "Solodok" (Ukraine) in the amount of 3.0 % to the mass of flour in the production of pastry products in whose formulation 50 % of flour was replaced with a mixture of germinated grains. The application of the polycomponent mixture "Solodok" has a positive effect on the organoleptic and structural-mechanical properties of the product crumb. The composition of the polycomponent mixture includes safe food additives and ingredients such as ground cinnamon, dry wheat gluten, apple pectin, and ascorbic acid. It has been proven that products with the addition of the polycomponent mixture retain freshness longer, which was confirmed by a lower rate of staleness, by 59.2 %, compared to control. The stale processes in the case of using a polycomponent mixture are inhibited due to the greater accumulation of dextrins compared to control. Thus, the total content of dextrins in a pastry product is 1.668 % to DM (dry matter) while in the bun "Tsilyushcha", it is 2.443 % to DM. The study results show the technological effectiveness of the use of the "Solodok" polycomponent mixture to slow down the staleness of products and provide products enriched with a mixture of germinated cereals with satisfactory consumer properties

    Development of a recipe for a «Solodok» multicomponent mixture to improve the quality of pastries
    (2021) Bilyk, Olena; Burchenko, Liudmila; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia
    The object of research in this work is a baked product enriched with a mixture of sprouted grains, ground cinnamon, apple pectin, dry wheat gluten, ascorbic acid. Pastries occupy an important place in the production and sale of food products and have a high calorie content. To reduce the energy value of pastry products, it is proposed to replace wheat flour in the recipe with a mixture of germinated grains of wheat, oats, barley and corn. In this work, the properties of such mixtures were studied using the example of a mixture of the «CHOICE» company (Ukraine). The mixture of germinated grains of cereals of wheat, oats, barley and corn of this company is rich in dietary fiber, nonessential and irreplaceable amino acids, microelements and macroelements, vitamins. It has been established that a rational substitution of premium wheat flour for a mixture of germinated grains in the recipe for pastry products is 50 %. Due to the germination process, a large amount of amylolytic and proteolytic enzymes accumulates in cereals, which impair the structural and mechanical properties of the crumb of pastry products, as a result of which the crumb of the product becomes sticky and wrinkled. The work was aimed at developing a multicomponent mixture to improve the quality of pastry products, the formulation of which includes a mixture of germinated grains. A «Solodok» multicomponent mixture has been developed, which has a positive effect on the organoleptic and structural-mechanical properties of the product crumb. The mixture contains safe food additives and ingredients: ground cinnamon, dry wheat gluten, apple pectin, ascorbic acid. It has been established that the introduction of the «Solodok» multicomponent mixture into the dough leads to the replacement of the fermentation process with the stage of sedimentation. The use of a multicomponent mixture leads to an improvement in the organoleptic characteristics of rich products, an increase in the specific volume of products, and an improvement in the development of the porosity of products. Adding a mixture of sprouted grains and a «Solodok» multicomponent mixture leads to a change in the traditional taste, the products acquire a pleasant aftertaste of sprouted cereals and cinnamon. The use of a mixture of germinated grains and a «Solodok» multicomponent mixture in the recipe for pastry products leads to a decrease in the energy value of pastry products in comparison with the control.

    The use of an enzyme preparation when using calcium acetate in wheat bread technology
    (2019) Bilyk, Olena; Kochubei-Lytvynenko, Oksana; Bondarenko, Yuliia; Chernyushok, Olga
    An 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.

    Studying the effect of electrospark treatment of milk whey on the process of its fermentation and quality of thermoacid cheese
    (2019) Kochubei-Lytvynenko, Oksana; Chernyushok, Olga; Bilyk, Olena; Bondarenko, Yuliia
    The paper reports a study into the influence of electrospark dispersion of current-conductive granules of magnesium and manganese in the environment of milk whey on the process of its fermentation in the technology of making soft thermo-acid cheeses the type of "Adyheyskyy". The object of this study was milk whey, obtained from the thermo-acid settling of cheeses. To prepare the coagulant, it was treated in an electric discharge chamber with a current-conductive layer of magnesium or/and manganese granules manganese over 30...120 s. It has been established that the result of such a treatment of milk whey is the increased magnesium content, by 1.8 to 4 times on average, and the increased manganese content, by 1.5 to 3.8 times on average, depending on the treatment duration. It has been proven that it was characteristic, of all the examined samples, to demonstrate a natural growth of titrated acidity during fermentation. However, the samples enriched with mineral elements following the electrospark treatment over 30...60 s have shown a more intensive growth in titrated acidity. Similar results were obtained when using milk whey from cottage cheese. Although at the initial stages of fermentation (0...6 hours) the increase in acidity was somewhat slower, which has an objective explanation related to the effect of enhanced acidity of the starting whey (50...60 °T) on lactobacilli. It was established that the production cycle is significantly reduced in case of using the proposed technology of acidic whey-coagulant for making thermo-acid cheeses. There is also an increase in the utilization coefficient of technological equipment and its resources. A given technology does not require significant areas for the introduction of an innovative electro-physical technique, and, instead, given the reduced fermentation time, it contributes to reducing the number of containers involved in the preparation of coagulant. It has been established that the use of acidic whey, produced from raw materials enriched with magnesium and manganese, in the technology of thermo-acid cheese contributes to its enrichment with valuable mineral elements. It also provides for a more complete use of the protein potential of milk and, consequently, increases the thermo-acid cheese yield by 1.8...6.5 %

    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, Volodymyr
    Dry 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

    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, Albina
    Scientists 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.
