Study of visual, sensorial and physicochemical characteristics of Tommy Atkins mangoes submitted to ionising radiation as a method of postharvest conservation
With the objective of evaluating the effect of ionising radiation on the main characteristics of postharvest quality of mangoes (Mangifera indica L), fruit of Tommy Atkins cultivar have been irradiated with gamma rays from a cobalt-60 source. Doses of 200, 400 and 600 Gy were applied, and non-irradiated fruit served as control. After being stored for 15 days at 11.5?C, to simulate transport conditions, the fruit remained stored at 21?C for up to nine days. During this period, sensory and physicochemical analyses were performed after three, six and nine days. Control fruits had higher maturation index and a higher acceptability in the external and internal appearance. Physicochemical analyses disclosed that fruit that had received doses from 400 and to 600 Gy showed better postharvest characteristics after storage.
