Chitosan/gelatin-based functional films were fabricated by incorporating cinnamon essential oil (CEO) and rutin for active packaging application. The functional fillers were evenly distributed in the polymer matrix and formed a film compatible with the chitosan/gelatin polymer matrix. However, the functional material did not affect the physical properties such as mechanical, thermal, and water vapor barrier properties of the film but exhibited high light transmittance with enhanced UV blocking properties. The rutin release from the composite film was evaluated using various food simulant solutions and found that rutin was released faster in acidic and alcoholic solutions. The chitosan/gelatin-based composite film showed potent antimicrobial and antioxidant activities. In addition, the combined use of CEO and rutin showed a synergistic effect of functional properties. The CEO and rutin-added chitosan/gelatin-based films with improved physical and functional properties can be used for active food packaging applications.
壳聚糖/明胶基功能薄膜通过掺入肉桂精油（CEO）和芦丁，用于活性包装应用而制备。功能填料均匀地分布在聚合物基质中，并与壳聚糖/明胶聚合物基质形成相容的薄膜。然而，该功能材料并不影响薄膜的物理性能，如机械性能、热性能和水蒸气阻隔性能，但具有高透光率和增强的紫外线阻挡性能。通过使用各种食品模拟溶液评估了芦丁从复合膜中的释放情况，发现芦丁在酸性和酒精溶液中释放得更快。壳聚糖/明胶基复合膜表现出强大的抗菌和抗氧化活性。此外，CEO 和芦丁的联合使用显示出功能特性的协同效应。具有改善的物理和功能特性的 CEO 和芦丁添加的壳聚糖/明胶基薄膜可用于活性食品包装应用。
