摘　　要：以新疆库尔勒香梨为试材,采用1-甲基环丙烯(1-MCP)处理结合低温贮藏的方法,研究了1-MCP处理对香梨贮藏过程中常规指标和多酚及抗氧化活性的影响,以期为库尔勒香梨保鲜提供参考依据。结果表明:库尔勒香梨在4℃和相对湿度90%~95%的条件下,采用1-MCP处理显著抑制了果实硬度、总酸、葡萄糖、蔗糖和山梨醇的下降,延缓了果实的可溶性固形物峰值到达时间,保持总酚、熊果苷、儿茶素、绿原酸和芦丁含量,抑制果实抗氧化能力的下降。综上可知,采用1-MCP处理能够有效保持香梨贮藏品质,延缓香梨酚类化合物含量和抗氧化活性的下降。Xinjiang Korla fragrant pear were used as the experimental materials,and the method of 1-methylcyclopropene(1-MCP)treatments combined with low temperature storage were used,the effects of conventional indexes,polyphenols and antioxidant activity of fragrant pear during storage were studied,in order to provide reference for the preservation of Korla fragrant pear.The results showed that Korla fragrant pear,treated with 1-MCP and stored at the conditions of 4℃and 90%-95%relative humidity,significantly inhibited the decrease of hardness,total acid,glucose,sucrose and sorbitol,delayed the peak arrival time of fruit soluble solids,retained the content of total phenol,arbutin,catechin,chlorogenic acid and rutin,and kept the antioxidant activity.In conclusion,the 1-MCP treatment could effectively maintain the storage quality of fragrant pear,delay the decrease of the content of phenolic compounds and antioxidant activity.
