摘要
以新鲜猕猴桃为材料,研究了在正常低温保鲜过程中过氧化氢酶(CAT)、过氧化物酶(POD)、超氧化物歧化酶(SOD)活性的变化,进而推测其在水果保鲜过程中的作用。结果表明SOD、CAT活性随时间延长而减弱,变化动态呈S型曲线,表现出一定的平行性;POD活性则先升高后降低,变化动态呈单峰曲线。
The experiment was conducted to explore the dynamic variation of activities of CAT, SOD and CAT enzymes during the normal low - temperature preservation process of Chinese gooseberry. Results showed that the activity of SOD and CAT enzymes reduced in a S - shaped curve, roughly correlated with each other during the dynamic variation ; nevertheless, the variation of activity of POD took on a single - peak curve.
