Abstract

At present, «Strategy for Improving the Quality of Food Products in the Russian Federation until 2030» is the main document in the field of healthy nutrition. According to it, the main direction in this area is to provide the Russian population with nutritious food products, which will ensure the prevention of nutritional diseases and lead to to increase the life expectancy of the population, as well as improve their quality of life and to stimulate the production of quality products. At the same time, the need to use domestically produced raw materials, as well as functional ingredients from these raw materials in the production of a wide range of products for healthy and preventive nutrition, is clear lystated. The importance of using local plant, fruit and other raw materials, which are a source of many deficient vitamins, minerals, insoluble and soluble dietary fiber, as well as other valuable nutrients should be noted. In addition, local fruit raw materials are climatically adapted to the living conditions of humans in a particular region. In this regard, research aimed at analyzing the nutritional value of common regional fruit raw materials of the Central Chernozem Region (CCHR) and other regions of Russia is necessary. Of particular importance in the study of the nutritional value of berries and fruits as multivitamin crops that have a complex of medicinal and preventive properties. Among them are, undoubtedly, garden strawberries. The goal of the research is to study the consumer qualities and nutritional value of new varieties of garden strawberries. The article presents the results of a comprehensive assessment of the consumer qualities of the berries of seven new, currently zoned varieties of garden strawberries of foreign selection grown in the Tambov region: Aprika, Vivara, Zephyr, Kwiki, Letitia, Lord and Sibilla. The quality of berry raw materials is determined by a combination of organoleptic and physicochemical indicators, nutritional value, as well as safety indicators. The results of organoleptic studies showed that the berries of all studied varieties had excellent taste. At the same time, the berries of the Aprica, Kwiki, Zephyr and Vivara varieties had excellent quality. These fruits are classified as having an excellent quality.
