摘　　要：以库尔勒香梨为研究对象,探究冷激处理(0℃浸泡10 min)对香梨贮藏品质的影响。结果表明,冷激处理能显著抑制库尔勒香梨贮藏期间维生素C、总糖、总酸、可溶性固形物、总酚、类黄酮含量的下降,并抑制多酚氧化酶活性的增加。至贮藏结束时,与对照组相比冷激处理的库尔勒香梨褐变指数减少了19%,明显低于对照,且增加的多酚氧化酶活性仅为对照组的68.75%。因此,冷激处理可以较好地维持贮藏期间香梨的品质,减缓香梨果实在贮藏期间的褐变程度,延长其贮藏期。In this study,Korla fragrant pear was explored the effect of cold shock treatment(soak at 0℃ for 10 minutes)on the storage quality of fragrant pear.The results showed that the cold shock treatment significantly slowed down the decreasing trend of vitamin C,total sugar,total acid,soluble solids,total phenols,flavonoids and inhibited the growth of polyphenol oxidase activity during storage.By the end of storage,the browning index of Korla fragrant pear was reduced by 19% compared with that of the control group,and the growth of polyphenol oxidase activity in the cold shock group was only 68.75% of that in the control group.Therefore,cold shock treatment could better maintain the quality of fragrant pear during storage,slow down the browning degree of fragrant pear fruit during storage,and prolong its storage period.
