摘　　要：测试并分析与冬枣果实贮藏后多酚氧化酶、过氧化物酶和乙醇脱氢酶的活性变化。结果表明：适合的气调贮藏（O2体积分数12%-15%,CO2体积分数为0）可以明显抑制多酚氧化酶和过氧化物酶的活性,有效地延缓了多酚氧化酶活性高峰的到来,阻止了过氧化物酶活性的升高,可以达到较好的贮藏保鲜效果,延长冬枣的贮藏时间。气调贮藏可提高乙醇脱氢酶的活性,尤其是在贮藏后期这种作用更加明显。In this study the changes of Polyphenol Oxidase, Peroxidase and Alcohol dehudrogenase activities of ＇Dongzao＇ Jujube were analyzed respectively after storage. Fruits subjected in adaptive controlled atmosphere （12% - 15% O2,0 CO2） showed that the activities of Polyphenol Oxidase and Peroxidase declined significantly, the burst of the Polyphenol Oxidase activity was delayed effectively, and a late increase in the activity of Peroxidase, which resulted in improving the fruit quality retention during storage and extending the storage life. Taken together, the results suggested that Alcohol dehudrogenase activities were enhanced in controlled atmosphere storage, especially in the subsequent storage.
