ПЛОДЫ РЕДКИХ КУЛЬТУР КАК ИСТОЧНИКИ АНТИОКСИДАНТОВ ДЛЯ РАЗРАБОТКИ ФУНКЦИОНАЛЬНЫХ ПРОДУКТОВ ПИТАНИЯ

Abstract

The article deals with the creation of beverages with functional properties for the healthy nutrition of the country's population from the fruits of rare crops. The necessity of including functional foods with a high content of natural antioxidants that increase resistance to adverse environmental factors in the diet of the country's population is indicated. Chemical indicators of the quality of fruits of such rare crops as viburnum, rose hips, barberry and hawthorn have been studied. It has been established that viburnum fruits contain 18.5 mg/100 g of vitamin C, more than 100 mg/100 g of vitamin P, polyphenols; in rose hips – more than 100 mg/100 g of vitamin C, more than 200 mg/100 g of vitamin P, more than 2 mg/100 g of vitamin E, β– carotene and pectin substances; barberry fruits contain a high content of vitamins, polyphenols, β-carotene and minerals (up to 425.4 mg/100 g of potassium, up to 51.2 mg/100 g of calcium); hawthorn fruits contain vitamins C, P, E, polyphenols, β-carotene, potassium more than 598.0 mg/100 g and calcium more than 137.8 mg/100 g, which makes it possible to attribute them to the group of crops with a high content of macronutrients. Technological modes of preparation of extracts from fruits of rare crops are optimized, taking into account pH, temperature and hydrolysis time. Formulations of functional beverages have been developed using fruit extracts and puree from the fruits of barberry, viburnum, hawthorn and rosehip with a high content of antioxidants. The total content of natural antioxidants in the drink «Vitaminnyi» is 425.7 mg/100 g, in the drink «Zdorov’e» – 350,5 mg/100 g.
