壳聚糖衍生物──N，O－羧甲基化壳聚糖在猕猴桃保藏中的初步应用

A Preliminary Application of Chitosan Derivative─N, O-carboxymethyl Chitosan in the Storage of Kiwifruit

本文介绍由虾蟹壳制成Ｎ，Ｏ－羧甲基壳聚糖，并以其中性水溶性胶为被膜剂，在常温下做单果涂膜保藏的初步试验研究。结果表明，处理组Ｈ，保存３个月，商品好果仍为１００％，失重仅３％。

The preparation of N,O-carboxymethy chitosan from the shell of crab and shrimp are introduced.The preliminary experiment of using the water soluble N,O-CMC as a coating to keep kiwifruit fresh of ambient temperature are discussed. The results show that groo pH can keep the freshness of kiwifruit for 3 months, its commercial good grade fruit is 100% and the weight loss of them is about 3%.
