Preparation of Chitosan Composite Film Loaded with Chlorogenic Acid-Chitosan Oligosaccharide Nanoparticles and Its Application in Preservation of Pleurotus geesteranus.

ABSTRACT: To reduce the environmental impact of plastic packaging in the edible fungi supply chain, this study developed an edible natural chitosan composite film loaded with chlorogenic acid-chitosan oligosaccharide nanoparticles (CGA/COS NPs). The effects of CGA/COS NPs as additives on the structure and overall performances of chitosan-based films were systematically studied, and the application effect of nanoparticles/chitosan (NPs/CS) composite films in the preservation of Pleurotus geesteranus was explored. The results showed that the NPs had good compatibility with the film matrix, filled the voids of the chitosan matrix, enhanced the comprehensive performance of the film, and significantly improved the antioxidant activity of the film (DPPH free radical scavenging activity increased fr
