Progress on the preparation method, physicochemical properties, and application of chitosan-based film

The chitosan-based film, a cling film commonly used with wide application potential, is the focus of this research. Chitosan, a molecule that readily binds with other molecules, possesses the capability to enhance the physicochemical properties of the film when combined with other active substances. The progress made in enhancing the properties of chitosan-based film through the incorporation of other substances is a significant area of investigation. In this article, examples of improved mechanical, antioxidant, barrier, and water uptake properties are listed and discussed. Furthermore, the preparation method of chitosan-based film is thoroughly examined. Ultimately, the synthesis of the application of chitosan-based film in food preservation is presented.
