Studying the composition of a tomato supernatant

One of the ways to improve people's health through food is the industrial production of products, the so-called "health" group, which currently includes soft drinks, including special-purpose ones. Drinks are the most technologically advanced basis for creating new types of functional products. Soft drinks are widely used in therapeutic and preventive nutrition. They are useful not only for the normalization of water-electrolyte metabolism, but also for optimizing the chemical structure of the diet. One of the promising functional components of beverages obtained during the production of lycopene from tomatoes is a supernatant. There is no information about its component composition in the available literature. A qualitative and quantitative study of the supernatants of tomatoes of different varieties is given. Some carbohydrates, water-soluble vitamins, micro- and macronutrients, organic acids, and flavonoids have been identified. The identified nutrients that are part of the tomato supernatants allow them to be used in soft drinks, including for special purposes. The study of the content of micro- and macronutrients did not reveal significant differences in the supernatant obtained from different varieties of tomatoes, but it is worth noting a fairly high content of iron and copper. It was found that the largest amount of vitamin C was found in a supernatant obtained from tomatoes of the Volgogradsky variety. Despite the fact that the supernatant is a by-product of carotenoid production, it has a range of nutrients that are certainly valuable to humans and can be used in food technology, in particular soft drinks, including special-purpose ones. The next stage of the work will be the development of a technology for preparing a special-purpose drink using supernatants obtained from different varieties of tomatoes. The research was carried out at the expense of a grant from the Russian Science Foundation № 23-26-00217, https://rscf.ru/project/23-26-00217/
