Chitosan can be used in vegetables, meat products, seafood, starch, soybean products, eggs, milk and bean products. After picking fruits and vegetables, due to the influence of physiological maturity, they will soften, leading to the decline of hardness, which brings difficulties to transportation, quality and nutritional value decline, and the resistance to bacteria is also weakened.Therefore, how to keep fresh of fruits and vegetables has been concerned for a long time. Chitosan has film-forming properties,not only harmless to human body, but also has physiological health care function. Its protective effect on fruits and vegetables is more and more recognized by people. Covering fruits and vegetables with chitosan can reduce the transpiration of fruits and vegetables, and has a certain selective permeation effect on gas. It can prevent the external O2 from entering the membrane,increase the content of CO2 in fruits and vegetables tissues and reduce the ethylene emission, thus reducing the respiratory metabolism intensity of fruits and vegetables, slowing down the ripening of fruits and vegetables, and achieving the purpose of preservation.
