Postharvest preservation of fruits is one the key issues in current agriculture and food processing industry. Surface coating treatment, a promising technology for postharvest fruit preservation, has gathered significant attention due to its ability reduce water loss, regulate gas exchange, inhibit respiration, thereby achieving preservation. Among them, chitosan-based wide application prospect superior film-forming capability, high biosecurity, range sources, etc. This review summarizes structural features, physicochemical properties, modification strategies, mechanisms coatings, focusing on their applications storage. Unlike prior works, it highlights advanced modifications (e.g., nanocomposite, multifunctional grafting) that enhance antimicrobial activity, mechanical strength, environmental adaptability. Challenges preservation—such as microbial resistance stability—are analyzed, with solutions proposed via material innovation. The discussion industrial scalability emphasizes chitosan’s biodegradability, cost-effectiveness, alignment sustainable agriculture, while addressing technical bottlenecks. work bridges fundamental research practical use, advancing coatings toward greener, safer, scalable solutions.
