Abstract:

Effects of pre-storage chitosan coating in combination with post-storage 1-methylcyclopropene (1-MCP) exposure treatment on quality of plum (Prunus salicina Lindl cv. Niuxin) fruit during shelf life were studied. Results showed that after plum fruits were coated with 10, 15 or 20 g/L chitosan solutions, stored at 2 ℃ for 4 weeks and then exposured to 1.0μl/L 1-MCP during shelf life at 23~25℃, the change of firmness, vitamin C content and surface color were delayed, and decay was inhibited. Treatments of chitosan combined with 1-MCP exhibited better effects than chitosan or 1-MCP treatment alone, and could significantly improve the plum fruit quality during shelf life.

Key words: chitosan, 1-methylcyclopropene (1-MCP), plum fruit, shelf life
