Development of technology for a non-alcoholic drink for dietary and preventive purposes

The justification of the use of everbearing raspberry varieties in the production of specialized products requires a study of the content of biologically active components in them in relation to the soil and climatic conditions of crop growth. The aim of the work was to determine the antioxidant potential of the berries of the everbearing raspberry variety "Poklon Kazakovu" grown in the Kabardino-Balkarian Republic, and to develop a technology for a non-alcoholic drink for dietary prophylactic purposes. The work used generally accepted and special physicochemical and biochemical research methods. It was found that the berries of the everbearing raspberry variety "Poklon Kazakovu" contain a complex of water- and fat-soluble vitamins, including antioxidants. The degree of satisfaction of the human body's needs when consuming 100 g of raspberries is covered in vitamin C by 30.2-100.7%; in folates and vitamin K – 1.7-4.6 and 3.0-12.0 times more than the daily requirement, respectively. The content of P-active compounds in raspberries of the Poklon Kazakovu variety was 552.7 mg/100 g. Based on the research results, a technology was developed for the production of a non-alcoholic drink for dietary prophylactic purposes using puree from everbearing raspberries of the Poklon Kazakovu variety, pectin extract from green pea pods, erythritol sweetener and Abiflor biocorrector. It was shown that the new drink is characterized by a high concentration of antioxidant substances – polyphenols (330.7 mg/100 cm3) and vitamin C (16 mg/100 cm3). It contains pectins in the amount of 1.12 g/100 cm3. 200 cm3 of the developed drink covers the human body's need for P-active substances, ascorbic acid and pectin by more than 15% of the recommended daily intake.
