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

The modern range of milk-based ice cream with an alcohol component was analyzed. The choice of alcoholic tincture in the composition of milk ice cream was substantiated. The cryoscopic temperature of the mixtures was determined using a measuring complex, the dynamic viscosity was determined by a Heppler viscometer, the melting resistance was determined by the melting time of the hardened ice cream samples, and the ice cream was whipped by the weight method. The possibility of using tinctures with an alcohol content of 20% as a part of milk ice cream has been scientifically confirmed. The selection of the structure stabilizer and rational modes of maturation of milk-alcohol mixtures were substantiated by the values of the coefficient of dynamic viscosity. According to the cryoscopic temperature of ice cream mixtures, it was found that the production of ice cream with a mass fraction of alcohol up to 3% determines the possibility of using conventional freezing modes to obtain a product of guaranteed quality. A new type of milk ice cream with the use of tinctures can be recommended for the introduction of the classical technological scheme of production with the clarification of maturation modes.

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.

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, Albina
Bread 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.
Justification of sedimentation stability of milk whey after electric spark processing
(2016) Kochubei-Lytvynenko, Oksana; Chernyushok, Olga; Rindyuk, Dmitry; Shutiuk, Kateryna
Introduction. The article focuses on the primary processing of milk whey, in particular, the prospect of its processing using electric spark discharges. Reasonability of the electric discharge application in whey processing technology is confirmed by experimental research as well as mathematical and statistical analysis. Materials and methods. Mathematical modeling established a rational mode of electrohydraulic treatment of whey which is accompanied by a maximum dispersion of particles of precipitated casein dust. Results and discussion. It has been confirmed that the average hydrodynamic diameter of milk whey particles decreased from 1697,5 ± 82,38 nanometer to 221,34 ± 0,3 nanometer after electric discharge processing with the peak voltage of 45 kV and discharge quantity of 25. The polydispersity index at that plummeted from 1,0 to 0,35...0,40, which characterizes the system as the one close to monodisperse state. We have noticed that at the voltage of 30 and 35 kV and the discharge number of 5... 15 the particle dispersion was insubstantial. The average particle size decreased only by 22...30%. It was also concluded that at the voltage growth as well as increase in a discharge number the peak values on the distribution curves shifted to the particle size of 500... 1000 nm, while the average hydrodynamic diameter decreased. The best results during the electrohydraulic milk whey processing were achieved at the voltage of 45 kV and the discharge number amounting to 25. The sediment volume in the processed whey decreased from 0,9... 1,1 to 0,1...0,2 cm3 at the voltage of 45 kV and the discharge number of 25. Conclusions. It is proposed a technological scheme of primary milk whey processing using electro-hydraulic method.

(2016) Ukrainets, Anatoliy; Marynin, Andriy; Sviatnenko, Roman; Pasichnyi, Vasyl; Kochubei-Lytvynenko, Oksana
Серед продуктів харчування значне місце належить рідким харчовим продуктам: безалкогольним напоям, пиву, молоку, натуральним винам тощо. Відомі технології подовження термінів зберігання цих продуктів базуються на термічному обробленні (пастеризація та стерилізація), застосуванні ультрафільтрації, добавках до продукту різних за своєю природою хімічних консервантів. При цьому харчові та органолептичні властивості рідких харчових продуктів суттєво погіршуються. Перспективним напрямом підвищення термінів зберігання цих продуктів є застосування електрофізичних методів а саме сильних імпульсних електричних полів без розрядів. Among food products, a significant place belongs to liquid food products: non-alcoholic beverages, beer, milk, natural wines and the like. There are known the technologies for lengthening the shelf life of these products, that are based on thermal processing (pasteurization and sterilization), the use of ultrafiltration, and adding to the product of various chemical preservatives in nature. In this case, the food and organoleptic properties of liquid food products significantly deteriorate [1]. A promising direction of increasing the shelf life of these products is the use of electrophysical methods, namely strong pulsed electric fields without discharges.
