摘要：
The function of chitosan film was reinforced by ZnO nanoparticles and antioxidant of bamboo leaves (AOB) for food packaging application. The results of structural characterization indicated the good compatibility among chitosan, ZnO nanoparticles and AOB. The chitosan film had the best mechanical strength and the highest light transmittance. The addition of AOB remarkably reduced the UV light transmittance and significantly enhanced the antioxidant activity of the films. Meanwhile, AOB and ZnO nanoparticles synergistically enhanced the antibacterial activity against E. coli and S. aureus. Our results suggested that the chitosan/ZnO/AOB films could be applied as potential active packaging materials in food industry to extend the shelf-life of packaged food.
