Edible mushrooms are prone to deteriorate during storage. A Single chitosan film or coating has limitations in preservation. Therefore, this article focused on the improvement of modified chitosan-based films and coatings on properties related to storage quality of edible mushrooms (e.g.: safety, barrier, mechanical, antioxidant and antibacterial properties). Besides, the application of chitosan-based materials in the preservation of mushrooms was also discussed. The modified chitosan film and coating can slow down the respiration of mushrooms, inhibit the growth of microorganisms, protect antioxidant compositions, and regulate the activity of related enzymes, thus improving the quality and prolonging the shelf life of mushrooms. Meanwhile, the added ingredients improve the water and gas barrier properties of chitosan through volume and group occupation, and reduce the light transmittance of chitosan through light transmission, scattering and absorption. Essential oils and polyphenolic compounds had a better enhancement of antioxidant and antimicrobial properties of chitosan.
食用蘑菇在储存过程中容易变质。单一的壳聚糖膜或涂层在保鲜方面存在局限性。因此，本文重点研究了改性壳聚糖基薄膜和涂层对食用蘑菇贮藏品质相关性能（如：安全性、阻隔性、机械性能、抗氧化和抗菌性能）的改善。此外，还讨论了壳聚糖基材料在蘑菇保鲜中的应用。改性壳聚糖膜和涂层可以减缓蘑菇的呼吸作用，抑制微生物的生长，保护抗氧化成分，调节相关酶的活性，从而提高蘑菇的品质，延长货架期。同时，添加成分通过体积和基团占据来提高壳聚糖的水和气体阻隔性能，并通过透光、散射和吸收来降低壳聚糖的透光率。精油和多酚化合物对壳聚糖的抗氧化和抗菌性能有更好的增强作用。
