doi:10.15933/j.cnki.1004-3268.2025.07.001

Abstract

Abstract: Fresh fruits and vegetables，due to their high water content and vigorous respiratory metabolism，are highly prone to quality decline and spoilage after harvest.As the world’s largest producer and consumer of fruits and vegetables，China has a persistently high post‑harvest loss rate of fruits and vegetables.The development of efficient and safe preservation technology has become an urgent need for the industry.Coating preservation technology is a new food preservation method，which can effectively maintain the quality of fresh fruits and vegetables and extend the shelf life of fruits and vegetables.Chitosan，as a natural biopolymer，is regarded as the most promising preservation coating material due to its wide source，degradability and biosafety，as well as excellent film forming property，antibacterial activity and biocompatibility.A systematic review is conducted on the basic characteristics of chitosan and the preparation methods of coatings.The research and application of chitosan coatings in the field of fruit and vegetable preservation are described in detail.The preservation effect of chitosan coatings on fruits and vegetables is discussed from the perspectives of appearance quality，nutrients，flavor substances and shelf life，and mechanism of preservation and the key factors affecting the preservation efficiency are summarized.Finally，the preservative chitosan coating technical bottlenecks and future development directions are pointed out，with the expectation of providing theoretical references for the in‑depth research and industrial application of this technology.

Key words: Chitosan, Coating, Storage and preservation of fruits and vegetables, Effect evaluation, Preservation mechanism, Influencing factor

摘要： 新鲜果蔬因含水量高、呼吸代谢旺盛，采后极易发生品质下降与腐败变质。我国作为全球最大的果蔬生产与消费国，果蔬采后损耗率居高不下，开发高效安全的保鲜技术已成为产业迫切需求。涂层保鲜技术是一种新兴的食品保鲜方法，可以有效维持新鲜果蔬品质、延长果蔬保质期。壳聚糖作为天然生物聚合物，凭借其来源广泛、可降解性和生物安全性，兼具优异的成膜性、抗菌活性及生物相容性，被视为最具应用前景的保鲜涂层材料。系统综述了壳聚糖的基本特性与其涂层的制备方法；详细阐述了壳聚糖涂层在果蔬防腐保鲜领域的研究与应用，从外观品质、营养物质、风味物质和保质期等角度讨论了壳聚糖涂层对果蔬的保鲜效果；并归纳总结了其防腐保鲜的作用机制及影响保鲜效能的关键因素；最后指出壳聚糖涂层保鲜技术的瓶颈与未来发展方向，以期为该技术的深入研究和产业化应用提供理论参考。
