Abstract
Abstract The frozen storage of capsicum tissue for 1 year at −12°C resulted in appreciable losses (from 10 to 58%) of ascorbic acid dependent upon the cultivar and the extent of tissue blanching. Ascorbic acid retention was maximal, but retention of chlorophyll a was minimal and pH dependent, in frozen blanched tissue which accordingly showed a greater increase in pheophytin formation. Sulphite treatment of unblanched tissue maintained acceptable colour through retardation of degradative interconversion and isomerization reactions of chlorophyll and carotenoid pigments during frozen storage.
