摘要: 以新鲜、无腐烂和黄化枸杞头为实验材料,采用不同温度(0、10℃和常温)和包装方式(挽口和敞口)进行贮藏,贮藏期间每4d测定失重率、腐烂率、超氧阴离子自由基(O2-·)和丙二醛(MDA)的含量及过氧化物酶(POD)的活性。实验结果表明:0℃低温和挽口包装可显著减少枸杞头的失重、腐烂的发生;0℃低温处理在降低枸杞头MDA和O2-·生成及POD活力方面作用明显,延缓了组织的衰老。

Abstract: The fresh sprout of Lycium chinense Mill after removing rotten and yellow leaves were packed in plastic bags loosely closed or opened,and then stored at 0,10 and 20 ℃,respectively. The weight loss,decay rate,contents of O2-·and MDA,POD activity were investigatesat at the interval of 4 days during the storage period. The results showed that 0℃ plus loosely closed packaging can significantly reduce the weight loss and decay rate of Lycium chinense Mill and 0℃ can also reduce the contents of MDA and O2-·and inhibit POD activity during the storage period of Lycium chimeses Mill. So the tissue senescence is postponed.
