Abstract
Ozone has been used as a postharvest treatment to delay the physiological and biochemical changes in fruit during storage. In this study, mango fruit (Mangifera indica L.) 'Nam Dok Mai No. 4' were fumigated with ozone at 2 μl L-1 for 20 min and 10 μl L-1 for 10 min before storage at ambient (25°C) and after three days of ambient storage. Ozone at 10 μl L-1 significantly decreased the respiration rate at day 4 and 6 compared with the control. It also decreased ethylene production which however increased on day 4 and 6, and resulted in lower peel L∗and b∗on day 4, lower pulp a∗, higher hue angle and lower weight loss on day 6 than that of the other treatments. Fruit firmness, soluble solid content and titratable acidity were not significantly affected.
