STUDY OF ANTIOXIDANT INDICATORS OF CHERRY FRUIT VARIETIES ZONED IN SVERDLOVSK REGION

Abstract

The article presents the results of a study of 11 varieties of cherry fruits released in the Sverdlovsk region. As a result of studies of antioxidant indicators, the highest values of antioxidant activity were, mmol/l equiv: in the period of early maturation – variety "Zadumka" – 31.995; in the period of medium ripening – the variety "Standard of the Urals" – 24.457; in the period of late ripening - variety "Alatyrskaya" – 30.610; the lowest value of the studied indicator in the variety "Flaming" – 7.799. At the same time, the highest content of flavonoids is observed in such varieties of cherry fruits as, mg / 100 g of the edible part, the "Zadumka" variety – 147.0±4.4, the “Ural Standard” variety – 112.4±3.4 and the variety "Alatyrskaya" – 140.6±4.2; the highest content of anthocyanins is observed in such varieties of cherry fruits as, mg cyanidin-3-glycoside / 100 g of edible part, variety "Zadumka" – 650.0±19.5, variety "Ural Standard" – 702.6±21.1 and promising variety "13-24" – 692.1±20.8; the highest content of phenolic substances is observed in such varieties of cherry fruits as, mg of gallic acid / 100 g of edible part, variety "Zadumka" – 51.6±1.6, variety "Mayak" – 75.9±2.3 and promising variety "13-24" – 93.2±2.8. In addition, such consumer characteristics of berries as the content of total and reducing sugars, as well as acidity, were studied. The data obtained will make it possible to more correctly calculate the nutritional value of diets and reasonably choose one or another variety for dietary correction of the diet in order to increase the overall antioxidant activity.
