摘要: [目的]为解决1-MCP和乙烯吸收剂在猕猴桃贮藏保鲜应用上的问题。[方法]以徐香猕猴桃为试材,研究了1-MCP和乙烯吸收剂对果实贮藏期及货架期果实成熟衰老和品质的影响。[结果]结果表明,1-MCP和乙烯吸收剂均显著地抑制了果实乙烯释放、呼吸作用和脂氧合酶(LOX)活性,使果实硬度下降和营养物质消耗趋缓,延长了果实贮藏期和货架期。1-MCP抑制了猕猴桃果实贮藏期和货架期酯类物质的合成,并在货架期积累了较多的醛类和醇类物质,对果实的风味品质有一定不利影响;乙烯吸收剂处理的果实货架期内酯类物质含量上升较快因而具有较好的风味品质。[结论]综合评价,乙烯吸收剂处理可更好地保持猕猴桃贮藏品质。

Abstract: The paper aims to study the application of 1-methylcyclopropene (1-MCP) and ethylene absorbent to kiwifruit preservation. The authors took‘Xuxiang’kiwifruit as the experimental material, to explore the effect of 1-methylcyclopropene and ethylene absorbent on ripening and fruit quality during storage and shelf life. The results showed that 1- MCP and ethylene absorbent significantly inhibited kiwifruit’s ethylene evolution, the respiration rate and the lox activity, evidently slowed down the decrease of fruit firmness and the depleting of nutrient substances, and extended the storage time and shelf life. 1- MCP inhibited the synthetizing of esters during the storage and shelf life, accumulated aldehydes and alcohols in the shelf life, which were unfavorable to the aroma quality of the fruit. The aroma quality of fruit was improved by the ethylene absorbent, which promoted the rising of the lactones content during the shelf life. By overall consideration, ethylene absorbent could significantly maintain the storage quality of kiwifruit.
