Comparative evaluation of the biochemical composition of berries of promising black currant varieties
Black currant is one of the most common berry crops, which is valued for its high winter hardiness, precociousness, yield, the possibility of mechanized care and harvest, therapeutic and dietary indicators of berries. These features of currant create economically advantageous conditions for widespread industrial and garden cultivation of crops in the conditions of the Central Black Soil Region. The article presents the nutritional and medicinal advantages of fresh black currant fruit. The requirements for commercial qualities of berries of modern varieties of culture are indicated. The experimental data of the biochemical composition of the berries of five varieties of the collection of the Federal Research Center named after I.V. Michurin ". The authors noted varieties with high levels of soluble solids, ascorbic acid, organic acids, sugars and pectin. Indicators of biochemical composition with low variability. The study of the biochemical composition of black currant varieties of berries made it possible to isolate promising varieties and sources for industrial cultivation, amateur gardening, the food industry and breeding for a high level of biologically active substances. Among the studied varieties, berries of the following varieties have a high level of biologically active substances: Chernavka, Green Haze, Carmelita. Varieties with high sugar content of Minx, Elevest and Green Haze. Varieties with high gelling properties with a high level of Pectin Chernavka and Minx.
