Abstract

The present study studied the effect of chitosan coating with antibrowning agents, including naphthylacetate and cinnamon oil, and modified atmosphere packaging (MAP) on browning of sweet persimmons stored at - 0.3 ~ 0 °C for 3 months. The browning on the surface of sweet persimmons was effectively inhibited by chitosan - based coating and MAP treatment. After 3 months’ storage, samples coated + MAP exerted the lowest browning index(BI), polyphenol oxidase (PPO) activity and malondialdehyde (MDA) content, which indicated that the coated + MAP treatment could offer an excellent inhibitory effect on the browning. Both edible coating and MAP treatment cause changes in respiration rate of sweet persimmons. This research could be valuable for the development of application to edible coating and MAP for improving the shelf - life properties of sweet persimmons.
