摘要：Chitosan is a modified and natural carbohydrate polymer which is obtained from the partial deacetylation of chitin, and includes the copolymer of glucosamine and N-acetyl glucosamine. Chitosan, which is a microbial polysaccharide, is used as an antimicrobial agent for its bacteriocidal and fungicidal functions. In addition to these properties, it is also used for edible film-forming, reducing the acidity of fruit juices, fining agent, browning inhibitor, and color preservative in the fruit and vegetable industry. Chitosan as a biopolymer can be obtained from many natural sources, has a wide application area in the fruit and vegetable industry due to its non-toxic properties involving living organisms, its biodegradability, biocompatibility, chemical, and physical properties because it shows superior features compared to the other biopolymers. In this review, the use of chitosan, which has not been used as a widespread application in the fruit and vegetable processing industry, will be summarized.
