摘要/Abstract

摘要： 为探究1-甲基环丙烯（1-methylcyclopropene，1-MCP）结合魔芋葡甘聚糖/κ-卡拉胶（konjac glucomannan/κ-carrageenan，KGM/KC）涂膜处理对梨的保鲜效果，以‘苏翠1号’梨为实验材料，研究清水（对照组）、1-MCP、KGM/KC涂膜、1-MCP＋KGM/KC涂膜4 种处理对梨货架期品质和活性氧代谢的影响。结果表明，1-MCP和KGM/KC涂膜处理均可以延缓梨货架期品质下降；与单独处理相比，1-MCP＋KGM/KC涂膜处理可更有效地降低梨果实采后呼吸强度和乙烯释放速率，提高梨果实超氧化物歧化酶、过氧化物酶和过氧化氢酶等抗氧化酶活性，降低超氧阴离子生成速率，减少过氧化氢和丙二醛积累，延缓梨果实硬度、抗坏血酸、可溶性糖和可滴定酸含量下降。综上，KGM/KC涂膜可以保持梨的货架期品质，1-MCP＋KGM/KC涂膜处理可以更有效地延缓梨品质下降、延长梨的货架期，为其在梨采后保鲜中的应用提供了参考。

Abstract: In order to study the effect of 1-methylcyclopropene (1-MCP) combined with konjac glucomannan/κ-carrageenan (KGM/KC) coating treatment on the preservation of pears, ‘Sucui 1’ pears subjected to one of four treatments: water (control), 1-MCP, KGM/KC coating, and 1-MCP + KGM/KC coating was evaluated for quality and reactive oxygen species metabolism during shelf life. The results showed that both 1-MCP and KGM/KC coating treatments delayed the decline in the quality of ‘Sucui 1’ pears. Compared with the single treatments, 1-MCP + KGM/KC coating treatment reduced the postharvest respiration intensity and ethylene release rate, and improved the activities of antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT). Furthermore, it significantly inhibited the production rate of superoxide anion radical, reduced the accumulation of H2O2 and malondialdehyde (MDA), and delayed the decrease in the hardness and the contents of ascorbic acid, soluble sugar and titrable acid in pear fruits. In conclusion, KGM/KC treatment could maintain the quality of ‘Sucui 1’ pears during shelf life, and 1-MCP + KGM/KC coating treatment could more effectively delay the quality decline and extend the shelf life of ‘Sucui 1’ pears, providing a reference for its application in post-harvest preservation of pears.
