摘要:

以油梨果实为原料,以不同浓度的1- 甲基环丙烯 (1-MCP)、乙烯利和壳聚糖涂膜处理对油梨果实的完熟天数和腐烂程度进行了研究。实验结果表明,贮藏在常温条件下 (25~35℃,平均相对湿度85%)的油梨果实其后熟时间的长短与1-MCP 的浓度相关,且随着1-MCP 浓度的提高,果实的后熟时间延长;壳聚糖涂膜处理可显著降低油梨果实的腐烂程度。壳聚糖涂膜的时间越早,防腐的效果越好;1-MCP 处理的浓度高于100nl/L 的情况下,壳聚糖的防腐作用更加明显;对于仅用乙烯利催熟的油梨果实没有必要进行壳聚糖涂膜处理。乙烯利处理3d 后也没有必要用1-MCP 和壳聚糖处理。

Abstract:

The effects of 1-methylcyclopropene (1-MCP), ethephon and chitosan coating on days from harvest to ripeness (DHR) and severity of body rots (SBR) in ripe avocado fruit storage at room temperature and relative humidity (RH) 85% were investigated in this study. The results indicated that the DHR positively depends on 1-MCP dose, while the SBR is significantly reduced by chitosan coating. Chitosan coating is applied earlier to avocado fruit, the rotproof efficiency is better. When 1-MCP concentration is higher than 100 nl/L, the rotproof efficiency of chitosan is better. The ripening avocado fruit hastened by ethophon treatment do not need to be treated with chitosan coating. After 3 days treated with ethephon, the fruits do not need to be treated with either 1-MCP or chitosan coating.
