Abstract

This study investigated the effects of individual and combined coating of 30 g/L oxidized corn starch and 1 mmol/L acetylsalicylic acid (ASA) on the storage property of bartlett pear at 0 ℃ and 85%-90% relative humidity. The results showed that ASA alone delayed the increase in weight loss and decrease in hue angle h0 during storage, but it had no significant effects on other indexes. When coated oxidized corn starch individually or in combination with ASA, both treatments effectively delayed the increase in weight loss and decrease in firmness, and maintained the color of peel. Moreover, both treatments inhibited the respiration rate of fruits, and combined treatment effectively delayed the respiration peak and inhibited malondialdehyde accumulation. However, the contents of total soluble solid and titratable acidity had no significant difference from the control. In conclusion, the combined treatment showed the best preservative effect, therefore, oxidized corn starch combined with ASA coating treatment can be used as a potential preservation technology to maintain postharvest quality of bartlett pear.

Key words： bartlett pear fruit; acetylsalicylic acid; starch; coating; fresh-keeping
