TOTAL ANTIOXIDANT CAPACITY OF POTATOES TUBERS
Abstract
Using the photoluminescence method, a total antioxidant capacity (ТАС) of 2105 potatoes tuber samples was determined on the «PHOTOCHEM» device. Samples differed according to the color of the skin and pulp, the intensity of staining, the degree of maturity of tubers, the duration of storage, the growing season conditions (meteorological and technological). The TAC of potatoes tubers varies from 32 to 9650 µM equivalent of ascorbic acid/100 g fresh weight, depending on the color of the peel and pulp. Potatoes tubers with purple skin TAC are 1.6 times higher than in tubers with red skin and 3.3 times higher than in tubers with yellow. Potatoes tubers with purple and red pulp TAC are 2.7 times higher than in samples with cream, yellow and white pulp. Samples of potatoes with cream, yellow and white flesh have the same TAC.
