摘要:

为改善贮藏后李果实品质和开发综合贮藏保鲜技术,研究贮藏前壳聚糖涂膜处理及其结合贮藏后1- 甲基环丙烯(1-MCP)熏蒸处理对货架期“牛心”李果实品质的影响。结果表明:贮藏前采用10、15、20g/L 壳聚糖溶液涂膜处理及其结合贮藏后采用1.0μl/L 1-MCP 熏蒸可以有效保持低温贮藏(2℃、4 周)后货架期(23~25℃)李果实的硬度,延缓果实VC 含量的下降和果皮色泽的转红,抑制果实腐烂的发生。壳聚糖和1-MCP 的结合处理比两者各自的处理效果都好,能进一步显著地改善李果实在货架期的品质表现,为李果实综合贮藏保鲜技术开发提供依据。

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
