INVESTIGATION OF PHYSICO-CHEMICAL AND ORGANOLEPTIC PARAMETERS OF HONEYSUCKLE VARIETIES

Fruit and berry raw materials are a valuable source of nutrients in the diet of the population of the Sverdlovsk Region. Among berry crops, blue honeysuckle (Lonicera caerulea L.) attracts special attention due to its rich biochemical composition, ease of cultivation and wide distribution in the Urals. The purpose of the study is to determine the organoleptic and physicochemical (mass fraction of reducing and total sugars, acidity) indicators of raw materials from honeysuckle fruits. Generally accepted standard physicochemical research methods were used. The material for the study was honeysuckle fruits of the varieties Polyanka Kotova, Bumerang, Amazonka, Nimfa, Lazurit, Bakcharskij Velikan, YUgana, Sil'ginka, Zinri, Gordost' Bakchara, Strezhevchanka, presented in a unique scientific installation of the collection of living open ground plants “Gene pool of fruit, berry and ornamental crops in the Middle Urals" of structural subdivision of the Sverdlovsk Horticulture Breeding Station of the URFANITS Ural Branch of the Russian Academy of Sciences (Sverdlovsk Region, Ekaterinburg). Among the studied varieties, the Polyanka Kotova, Zinri, Strezhevchanka, YUgana and Nimfa varieties stood out for their high organoleptic and physicochemical indicators, including the sugar-acid index (SAI). The results obtained can be used in the breeding process to select parental pairs for crossbreeding in order to obtain varieties with the highest possible biochemical characteristics; in further research related to the development of pharmaceutical formulations, as well as to expand the range and increase the nutritional value of dishes for catering establishments and the food industry.
