Essential Oil-Added Chitosan/Gelatin-Based Active Packaging Film: A Comparative Study

Active packaging films based on chitosan/gelatin were prepared using a solution casting method by adding various essential oils (lime, tea tree, rosemary, and thyme oils), their effects compared. The fabricated characterized physical properties as well the antioxidant performance of studied. Adding to polysaccharide/protein biopolymer mixtures resulted in compatible with high transparency (>90% transparency). mechanical strength stiffness improved about 30% presence oil, but flexibility slightly decreased, improved. On other hand, water vapor barrier properties, thermal stability, hydrophobicity oil-containing not significantly changed. enhanced activity chitosan/gelatin-based films. Therefore, bio-based functional added can be applied active applications.
