The article presents materials reflecting the developed exemplary 10-day menu of school breakfasts, lunches and afternoon snacks for the age groups of 7-11 years and 12 years and older for the organization and implementation of school meals in accordance with the requirements of SanPiN 2.3/2.4.3590-20. The scope of the developed materials includes schools and public catering enterprises that organize meals for schoolchildren based on the principles of healthy eating in accordance with the requirements of the Sanitary and Epidemiological Rules and Norms SanPiN 2.3/2.4.3590-20 «Sanitary and Epidemiological Requirements for the Organization of Public Catering of the Population « (approved by the Resolution of the Chief State Sanitary Doctor of the Russian Federation dated October 27, 2020 No. 32). When calculating the school menu, the requirements for the cost of a grocery set have been taken into account (no more than 58.39 rubles per day per student for the age category of 7–11 years and 12 years and older for school breakfast; no more than 58.39 rubles per day for one student of the age category of 7–11 years old and 65 rubles per day for one student of the age category of 12 years and older for a school lunch; no more than 18.75 rubles per day for one student of the age category of 7–11 years old and 22.75 rubles per day for one student of the age category of 12 years and older for a school afternoon snack). The developed exemplary 10-day menu of school breakfasts, lunches and afternoon snacks for the age categories of 7–11 years and 12 years and older have passed an examination in the Office of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Republic of Adygea and received a positive conclusion (01-00-03/58-4986-2021 dated August 27, 2021) and can be recommended for the use in educational institutions. The optimal period for the development (at least three months) and approbation (at least six months) of an exemplary school menu should be considered from six months to a year. In addition, the menu for school meals should be multivariate, including options for people with disabilities and other individualization. The new menu should be tested first in some educational institutions, and after adjustment by the developers, it is recommended for implementation. For the effective organization and implementation of school meals, a systematic approach to the issue of the formation of high-quality raw materials and a flexible pricing policy is required.

The article shows the prospects for the production of Mozzarella cheese of goat milk and dry sourdough. Cheese contains vital nutritional components, they are biologically complete and play an important role in the diet. Searching for new resources is an urgent problem. The solution may be to expand the range of cheeses not only of cow milk, but also of other farm animals, for example, goats. Their milk is absorbed faster and is used in medical and preventive nutrition. On the consumer market goat milk products are mainly represented by farms, and their range is small. The authors carried out the research on the selection of starter cultures containing probiotic cultures from bifidobacteria, acidophilus bacillus and thermophilic streptococcus, to optimize the technological process for the production of Mozzarella cheese based on goat milk. These cultures represent a beneficial microflora that inhabits the human body, helping to absorb nutrients and digest food. An important quality of probiotics that ensures their physiological effect is their high growth rate and compatibility with other microorganisms present in the gastrointestinal tract. It has been found that all the studied samples of goat milk in terms of composition have indicators that meet the requirements of GOST for goat milk. Comparative analysis of cow and goat milk has shown predominant indicators of the quality of goat milk in comparison with cow milk. The processes of coagulation and fermentation of goat milk under the influence of various starter cultures have been studied. The use of ABT-5-Probio-TecTM probiotic starter culture, which accelerates the technological process and imparts functional properties to the product, has been substantiated. The possibility of using goat milk in the production of cheeses with cheddaring and thermomechanical processing has been proven. Microscopic examination of a sample of Mozzarella cheese on ABT-5 sourdough has shown that bifidobacteria survive after heat treatment at high temperatures.
