Study of the chemical composition of various types of berries

Abstract

Berries play an important role in antioxidant protection, prevention and treatment of diseases of the human body, so many types of berries are widely used both in food and other industries. The purpose of this article is to study the chemical composition of berries of various species growing on the territory of Kazakhstan. The article presents the results of the organoleptic evaluation of berries, in a comparative aspect, the mineral and carbohydrate composition is studied, and the antioxidant activity of various types of berries is determined. The studies used generally accepted organoleptic, chemical and analytical methods. The results of the experiments performed will be used in the development of requirements for raw materials for processing, namely, berries of Kazakhstan production during freeze-drying.
