The aim of this study was to develop a concept of production for wheat bread enriched with chia seeds and to examine selected physicochemical properties. The examined product was wheat-flour bread made by a single-phase method, using yeast. The production concept assumed the modification of the recipe by replacing part of the wheat flour (1 or 5% w/w) with whole (CHw) or ground chia seeds (CHg). Bread quality was determined by calculating: dough yield, bread yield, baking loss, total baking loss and loaf volumes. Color was determined using the CIE L*a*b* system. In the texture analysis, the following texture parameters were measured: hardness, cohesion, chewiness and elasticity. The contents of crude fat, crude fiber, total protein, total ash and the total content of polyphenols were assessed to characterize the nutritive value of the bread. The breads with 1% addition of chia (1%CHw, 1%CHg) were characterized by the highest volume of loaves, which increased by at least 8.6% compared to the control bread (C), while in the case of 5% chia, the loaf volume depended on the form of seeds (better results were obtained with whole seeds). Substituting wheat flour with 1% chia seeds (whole or ground) resulted in a significant increase in nutritional value. For potential bread manufacturers, from a technological and economic point of view, replacing wheat flour with whole chia seeds at 1% (w/w) is most advantageous, compared to 5% (w/w).

Object of research: frozen fruits of black currant varieties Bilorus Sweet, Minai Shmyrev. Investigated problem: substantiation of the influence of the method, the duration of freezing on changes in the structure of black currant fruits of different degrees of maturity and pomological varieties. The main scientific results: the advantages of fast freezing of black currant fruits in a fast freezing chamber with forced air circulation at a speed of 1.5–2.5 m/s at a temperature of -30 …- 32 °C compared to slow freezing in " Calex " freezers were established at a temperature of -20 …- 22 °C. Rapid freezing forces cooling, freezing and freezing due to a decrease in the temperature of initiation of ice formation, an increase in the rate of heat extraction and an increase in the temperature of freezing. The area of practical use of the research results: food industry enterprises specializing in the freezing of plant products. An innovative technological product: the technology of freezing black currant fruits, which allows to extend the period of consumption of high-quality fruits with a preserved structure. Scope of application of an innovative technological product: nutrition of the population.

Many children are unable to receive natural nutrition for various reasons. In this case, children are transferred to artificial feeding. Artificial feeding is provided by dry milk formulas. Most powdered milk formulas on the market are made from cow's milk. But the chemical composition of cow's milk in many respects does not correspond to human milk. It is proposed to use mare's and sheep's milk to develop mixtures for baby food. Milk collected from farms in Eastern, Western and Central Ukraine was used. Powdered milk was obtained by spray drying. The calculation of formulations was performed by optimizing the chemical composition using the standard Simplex program. Dry milk formulas based on Ligans mare's milk and Agnus sheep's milk have been developed for feeding children from birth to 6 months. Studies of microbiological parameters of the mixtures have shown that during 12 months of storage in cardboard packs with an inner package of combined polymeric material, the obtained products retain quality. During this period, the content of vitamins that can break down during storage is also normal. Assessing the tolerability of Ligans and Agnus mixtures, it was found that with the use of mixtures, the incidence of colitis and flatulence began to decline rapidly. A decrease in the total level of IgE by 88...90% in the blood of children indicates the hypoallergenic properties of mixtures of Ligans and Agnus. The initial content of sIgA in coprofiltrates of breastfed infants has been shown to be almost indistinguishable from that of infants consuming Ligans and Agnus. Developed mixtures are recommended to increase the body's resistance. The effectiveness of the mixtures has been confirmed by medical and biological studies.

The process of ice formation in the pericarp of black currant depends on the pomological variety, the degree of ripeness of the fruit, and the method of freezing. During the slow and fast freezing of black currant, four ranges of fruit cooling temperatures are distinguished: 1) from the temperature of the fruit to the temperature of initiation of ice formation; 2) from the temperature of the front (initiation) of ice formation to the lowest possible temperature of the fetal mesocarp; 3) from the lowest possible temperature of the mesocarp to the lowest temperature of the fetal endocarp; 4) from the lowest possible endocarp temperature to fetal freezing temperature. Fast freezing boosts cooling, freezing and freezing from 37 min. (slow) up to 5.6 min. due to a halving of the temperature of initiation of ice formation, an increase of 1.3 times in the rate of heat extraction and an increase in the freezing temperature from –22...–24 °С (slow) to –20.8 °С. It is scientifically substantiated that the temperatures of freezing fruits significantly change the general existing recommendations (not higher than –18 °С) regarding the storage conditions of black currant fruits: with quick freezing, not higher than –21 °С, with slow freezing, not higher than –24 °С. The formation of the properties of black currant occurs during the growing season under various agro-climatic conditions and affects the parameters of ice formation indicators. The marketable condition, quality and organoleptic characteristics of black currant fruits depend on the method of freezing. The advantages of fast freezing of black currant fruits in a quick-freezing chamber with forced air circulation at a speed of 1.5–2.5 m/s at a temperature of –30...–32 °С in comparison with slow freezing in freezers at a temperature of –20 have been established. ..– 22 °С.
