Among different segments of the population of the Russian Federation, flour confectionery from biscuit dough is one of the most popular. In order to give them functional properties to increase the biological value, we used pumpkin in this work. Such an additive enriches the finished product with pectins, carotenoids and minerals. The introduction of pumpkin puree also has a positive effect on organoleptic characteristics, but increases the humidity of the finished product. Introduction to the recipe for biscuit pumpkin puree helps to increase the value of the indicator “water activity”. Researching the microbiological quality indicators in the products developed showed that between Aw and microbiological quality indicators such as QMAFAnM and the content of yeast and molds, a straightforward relationship is observed: an increase in the proportion of water in the finished biscuit cake mix leads to increasing in a total number of microorganisms and also increasing the microorganisms of spoilage. In the sample with 20% replacement of wheat flour with pumpkin puree, the value of Aw approaches the value characteristic of products with high humidity (0.9). Therefore, enriched biscuit semi-finished products have a shorter shelf life, it is advisable to produce them at public catering facilities.

The priority in improving the existing methods of processing fish is salting with the use of food additives with different functional orientations. The aim of the study was the development of preserves with the introduction of lactate-containing additives and using sonochemical technologies; examination of the quality of the products obtained according to organoleptic and microbiological safety indicators. The article proposes a resource-saving technology for the production of fish products with prolonged shelf life due to the use of a complex food additive consisting of lactic, acetic, propionic acids and their salts in different proportions with subsequent ultrasonic treatment using the ultrasonic generator of the Wave series model UZTA-0 2/22-OM. There was established the optimal mode of using the ultrasonic processing power of 75 W / m2 in the manufacture of fish preserves from herring. Organoleptic and microbiological quality indicators were studied during storage of preserved products with the addition of additives and ultrasonic treatment compared to the control. Organoleptic assessment was carried out on a five-point scale, microbiological indicators were studied by standard methods. The Dilactin Forte Plus dietary supplement in the composition of preserves in the amount of 3% and in combination with the use of sonochemical technologies makes it possible to obtain a safe high-quality fish product. Manufactured preserves at a storage temperature of 0 ± 2 ° C can maintain their high quality for 5 months.

Currently, malting barley is one of the most important crops that form the basis of the food business in the Russian Federation. Malting barley is imported to Europe, Asia, Africa and South America. While storing and transporting grain, its microbiological quality indicators play a very important role. Grain seeded with various microorganisms quickly loses its functional and technological properties, which negatively affects the quality of beer produced from it. According to the results of the studies, it was found that the contamination of barley with microorganisms is greatly influenced by various impurities that enter the grain mass during harvest. As well as various impurities in the grain mass of malting barley, the grains of other plants wheat, rye and oats were found in some samples in quantity of about 4%. There were also a lot of beaten barley grains, in some samples more than 2%. The moisture content of the grain mass also affects the seeding by microorganisms. Impurities had a higher humidity than grain, purified from impurities. To reduce the microbial contamination of brewing barley grains, it is necessary to thoroughly clean and refine the grain mass immediately after harvesting.

The health status of the population now has a tendency to worsen, which is associated with insufficient intake of essential micro and macro elements and a decrease in physical activity. It is growing in popularity among the population to attend fitness clubs to maintain their health and fitness. At the same time, emphasis is placed on a balanced diet with the ability to control calories consumed using the Internet of Things (IoT). The article presents an assessment of the quality of enriched meat products using the example of poultry cutlets according to organoleptic and physico-chemical indicators. Flax seeds in the amount of 6% and oatmeal in the amount of 5.2%, which can serve not only as a source of high-grade protein, but also omega-3 fatty acids, became enriching additives. It was found that enriched cutlets had a pleasant appearance, taste and smell, juicy consistency and satisfy the daily requirement for omega-3 fatty acids. When 100 g of enriched cutlets are consumed, the need for protein is satisfied from 16.15 to 25.34%, respectively, for people with high and low physical activity. A model has been developed for the use of enriched meat products in fitness diets with the analysis of energy consumption by means of fitness control.
