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.
壳聚糖膜的功能通过 ZnO 纳米粒子和竹叶抗氧化剂（AOB）得到增强，可应用于食品包装。结构特征的结果表明壳聚糖、ZnO 纳米粒子和 AOB 之间具有良好的相容性。壳聚糖膜具有最佳的机械强度和最高的透光率。AOB 的添加显著降低了紫外光的透过率，并显著提高了薄膜的抗氧化活性。同时，AOB 和 ZnO 纳米粒子协同增强了对大肠杆菌和金黄色葡萄球菌的抗菌活性。我们的结果表明，壳聚糖/ZnO/AOB 薄膜可用作食品工业中潜在的活性包装材料，以延长包装食品的保质期。
