Preparation of Elastic and Antibacterial Chitosan–Citric Membranes with High Oxygen Barrier Ability by in Situ Cross-Linking

Abstract

bacteria, probably owing to the citric acids. The results demonstrated that these materials have potential applications as membranes or protecting coatings for food packaging and successful cross-linking by means of amidation, and the Maillard reaction under the condition of vacuum drying can be probably applied as a green and alternative method for the fabrication of mechanically tough and antibacterial membranes, fibers, and gels.
