Study of antioxidant indicators of fruit and berry raw materials zoned in the Sverdlovsk region

Abstract. Fruit and berry raw materials are a valuable source of nutrients antioxidants in the diet population Sverdlovsk region [2]. The aim study is to determine total antioxidant activity fruit Ussury plum thorn growing territory region. Generally accepted standard physic chemical research methods were used. material for was fruits plum, represented by following varieties: Pionerka, Dostoynaya, Ural’skie zori, Shelest, Gorlitsa, as well Sergo, Tagil, Iset’, Ermak Horticulture Breeding Station – structural subdivision Ural Federal Agrarian Research Center Branch Russian Academy Sciences Ekaterinburg. Results. It established that horticulture breeding station can be an important indicators. largest values shown varieties plum: Iset’ 52,404 mmol/l × eq, 45,416 Sergo 32,748 Tagil 26,359 eq. Varieties have lower Thus, Dostoynaya late ripening variety - 23.993 Pionerka 21.644 In Gorlitsa Shelest average period, 18.776 17.842 lowest index early zori 4,713 mmol/ l addition, parameters such acidity, mass fraction reducing sugars studied all presented plums, organoleptic indicators given, results sugar-acid presented. Scientific novelty. new data obtained indicate use Ekaterinburg, future used promising functional biologically active substances, development formulations, more correct calculation nutritional value diets order increase activity.
