Nutritional value and quality of actinidia Actinidia kolomikta

Abstract

Actinidia berries are widely distributed and have high yield, as well as a significant content of biologically active substances. However, they have been left out of attention for industrial collection, processing, and retail sale. This study aims to assess the nutritional value and quality of actinidia berries in the Primorsky Territory, applying standard and recommended methods of analysis to determine their chemical composition and technological characteristics. Specifically, the content of dry matter in the berries of actinidia kolomikta has been found to reach 20.24%, with a high sugar content dominated by glucose and fructose. The study shows that actinidia berries are a rich source of ascorbic acid and organic acids, primarily represented by malic, citric, and oxalic acids. The weight of an actinidia berry in a variety mixture ranges from 1.6 to 4.9 g, with a total score of 4.8±0.1 for the tasting assessment of berries. According to GOST 31823–2012 the variety mixture of actinidia kolomikta berries belongs to the first commercial grade. The results suggest that actinidia berries are a promising raw material for the production of fruit and berry products and confectionery.
