壳聚糖在水果保鲜中的应用研究进展

Research Progress on Application of Chitosan to Postharvest Fresh-keeping of Fruits

水果采后保鲜是当前三农问题重点关注的问题之一。采用壳聚糖(CTS)对水果进行保鲜,可减免化学保鲜剂残留对人体健康造成的危害,避免物理保鲜成本高、操作难的缺点。本文综述了CTS的结构、保鲜机理及其在水果保鲜上的应用现状,分析了使用CTS在水果保鲜领域存在的问题和解决途径,并对其应用前景进行了展望。

Postharvest fresh-keeping of fruits is one of the important issues in the policy of ＂countryside, agriculture and farmers＂. The application of chitosan（CTS） in the storage of fruits could avoid the damage of chemical fungicides residue to human health, reduce the physical preservation costs and difficulty in operation. The paper summarized the structure, preservation mechanism and application status of CTS in storage of fruits, analyzed questions existed in application of CTS in fruits storage and proposed solution measures, and prospected the future application of CTS.
