摘  要：
为了探索抑制台湾青枣(Ziziphus mauritiana Lamk.)果皮褐变的绿色冷藏保鲜前处理技术及其抗活性氧损伤的生理机理,采用正交试验设计法,对台湾青枣果实进行浸钙、壳聚糖浸泡和温烫处理,探讨3因素处理后对冷藏台湾青枣果皮褐变的影响。结果表明:浸钙和温烫处理能抑制果皮褐变和降低果皮丙二醛(MDA)含量,而壳聚糖浸泡处理则加剧果皮褐变和提高果皮MDA含量;浸钙和温烫处理抑制果皮PPO活性,而壳聚糖浸泡处理则提高了果皮PPO活性;浸钙和温烫处理能提高果皮SOD和POD活性,壳聚糖浸泡处理则抑制了果皮SOD和POD活性;3因素处理对果皮CAT活性无抑制作用,在高峰期还呈现提高果皮CAT活性的效果。可见,浸钙和温烫处理能改善台湾青枣果实贮藏效果和减轻果皮活性氧损伤。

摘  要：
In order to research the green pre-treatment technology of Indian jujube fruits cold-storage inhibiting peel ’ s browning and the physiological mechanisms on anti-oxidation, the experiment was designed in orthogonal test. Indian jujube fruits were treated with 3 factors such as calcium and chitosan and hot water. The influences of the 3 factors on the peel ’ s browning of Indian jujube fruits were explored in this paper. The results indicated that: the treatments of calcium and hot water could inhibit the peel ’ s browning and reduced the content of MDA in peel, and the treatment chitosan could improve the peel ’ s browning and increased the content of MDA in peel. The treatments of calcium and hot water could inhibit the activity of PPO in peel, and the treatment chitosan could improve the activity of PPO in peel. The treatments of calcium and hot water could improve the activity of SOD and POD in peel, and the treatment chitosan could inhibit the activity of SOD and POD in peel. The treatments didn ’ t inhibit the activity of CAT in peel, and increased the activity of CAT in peel at the peak. In summary, the treatments calcium and hot water could improve the storage effects and loosen the injuries of reactive oxygen species in peel.
