Due to the increasing incidence of diabetes mellitus in the world and in Russia, the food industry is challenged to expand the assortment of various diabetic food products and to improve their quality. Diabetic food products must contain not only low-glycaemic components, but also vitamins, minerals that are necessary for normalization of metabolism. Nowadays, the assortment of diabetic food products is formed mainly by confectionery products with sugar substitutes. However, fruit-and- vegetable and berry raw materials can be used in the development of new functional diabetic products, as they contain valuable bioactive substances (vitamins, mineral salts, dietary fibres). This paper presents the research findings on the development of new types of diabetic products made of berry raw materials of Krasnodar Region. Pine strawberries and blackberries with plenty of biologically valuable components (vitamins, macro- and microelements) were used as raw materials for diabetic products. The sugar substitutes, such as sorbitol and beet pectin, were added to the formulations of new products. Beet pectin is characterized by a high complexing ability. Thich makes it possible to use it in medical and therapeutic food products. The main quality indicators, namely organoleptic and physicochemical characteristics, were determined in the tested raw materials and developed products. It was found that the tested varieties of strawberry and blackberry are rich in pectin substances and vitamin C and have a high sugaracid index. The formulated desserts are also distinguished by high organoleptic and physicochemical characteristics. Thus, they can be recommended for diabetic and preventive nutrition.
