Recently, there has been a need to conduct research on obtaining food additives based on natural raw materials, finding optimal methods of its processing, creating waste-free technologies, as well as expanding the production of food enriched with vitamins, protein and other components of increased nutritional value. It is known that about 500 species of wild raw materials grow in Northern Kazakhstan, which is a potential source of biologically active components. Many of these plants are not used in the food industry. The significance of the chemical components of fruits, vegetables and berries varies, but they are all necessary for a rational human nutrition. The demand for berries and other derivatives of their products has increased with the growth of global awareness about the role of these and other types of fresh fruits/foods, which has aroused increased interest in the scientific community not only in the study of their individual potential, but also in the development of functional foods enriched with berries. This paper presents a brief analytical review, organoleptic and chemical composition of the berries of irga and chokeberry. The influence of heat treatment on the chemical composition of juices has been determined. The optimal drying modes of the pomace of irgi berries and chokeberry have been investigated. The possibility and relevance of using these berries and squeezing berries as dietary supplements is substantiated. The study of the chemical composition of the berries of chokeberry and irga and its further use as dietary supplements in the food industry will help to create new enriched healthy foods for the population.
