Abstract : The biochemical and physiological parameters investigated during the storage of mangoes included ethylene production and levels of pectic substances, ascorbic acid, sugars, acidity, total carotenoids and total soluble solids. A radiation dose of 30 krad caused a ripening delay of 7 days in mangoes stored at 35-38 deg C. Referigeration did not appear to extend shelf life. Both irradiated and unirradiated mangoes ripened normally under various curing conditions, although the delaying effect of irradiation was maintained. Aspergillus niger and A. flavus were the main causes of spoilage.
