The aim of this study was to determine the optimal temperature ranges of milk fermentation by the microbial association Tibetan Kefir Grains and to set changes during the storage of the fermented milk product. The optimum technological parameters of milk fermentation by Tibetan Kefir Grains compliance are set. Compliance of these parameters ensures the desired metabolic processes and obtaining a dairy product with good organoleptic properties: fermentation temperature is 28±1 °С for 24 hours, acidity of the product is from 80 to 120 % lactic acid, the amount of lactic acid bacteria – (2.9±0.22) × 108 CFU/cm3, fungi – (3.7±0.27) × 104 CFU/cm3. It was found that during the storage of the fermented milk drink produced on the leaven Tibetan Kefir Grains at the temperature of 4 ± 1 °С for 10 days titratable acidity of the product increased by 1.2 times to 108.4 ± 8.3 °Т, the population of lactic acid bacteria (Lactobacillus fermentum and some other) and yeast (Saccharomyces spp and some other) remained at the initial level. This indicates that the finished fermented milk product can be stored without losing functional probiotic properties for at least 10 days and meets the requirements of the standard (ISO 4471). At the same time, at a temperature of +8 ± 1°С the expiration date of the fermented milk drink is decreases to 7 days.

There is a lack of protein products in the human diet, so balancing the nutritional composition of products remains an urgent task. The purpose of the study is to develop and determine the structural and mechanical characteristics of finishing processed products made from bean paste, demineralised whey powder, and coconut oil for confectionery. The main areas of technological use of confectionery pastes are developed: for applying to the surface of products as a layer; for creating flowers and shaped model products, as a decorative element for flour confectionery products. The study used food-grade white beans of the Mavka variety, demineralised whey powder made from whey with a 90% degree of demineralisation in accordance with TS U 15.5-00413890-089:2014. Rheological properties (resilience, elasticity, plasticity) were determined by a plane-parallel elastoplastometer of Tolstoy modification. The surface characteristics of pastes were studied using a dynamometer connected to a MiG-1.3 measuring device. The adhesive strength was determined by separating the steel plate from the bean paste. Empirical regression equations are obtained by correlation and regression analysis using the MATHCAD-14 software suite. The chemical composition of bean pastes with demineralised whey powder, their organoleptic quality indicators and structural and mechanical properties were determined to optimise the recipe composition to improve the functional and technological properties of confectionery pastes. The positive effect of the mutual use of beans and demineralised whey powder on the structural and mechanical properties of new finishing processed products was established. The improvement of the moulding capacity indicators at the concentration of 10-30% demineralised whey powder and 8% coconut oil in the composition has been proven. The reduction of stickiness in the compositions of bean pastes for modelling shaped products, coating confectionery, and making flowers as decorative confectionery products at a concentration of coconut oil up to 10% was established. Accordingly, the total scores of the developed descriptors were: 2.92 for decorative confectionery, 2.98 for coating confectionery, and 2.95 for modelling shaped products. A change in the colour intensity of bean paste compositions in the case of an increase in the concentration of demineralised whey powder is established, which allows expanding the technological methods of manufacturing shaped products. The developed technology and recipe composition allow obtaining high-quality, high-biological value, and low-calorie finishing processed products for confectionery

The issue of healthy eating has always been relevant, especially this problem has been exacerbated by the rapid development of food technology and the production of a significant number of semi-finished products. As a result, there is a need to develop new types of food, including unleavened and low-calorie bread, bakery products enriched with vitamins, minerals, plant supplements. The aim of the work was to substantiate the technology of bread production with the use of beet kvass and to investigate the physico-chemical quality indicators of experimental samples of finished products. Technological indicators that characterize the quality of bread: moisture, porosity, crumbliness, acidity were determined by generally accepted methods. Bread made with beet kvass has been found to have well-developed crumb porosity, does not crumble for a long time, hardens slowly, and is resistant to microbiological spoilage. The crumb is not deformed and elastic when pressed. Replacing part of the water during the kneading of wheat dough with beet kvass (50 % by weight of flour) makes it possible to intensify the maturation of semi-finished products, both in traditional and accelerated technologies, to create a more complete nutrient medium for yeast activation, to obtain high quality bakery products storage. It has also been found that during the storage of bread, the hydrophilic properties of the crumb, its crumbliness changes slightly. The drying process is most intense during the first day, then slows down.
