Abstract
as compared to the neat chitosan/gelatin film. Practical studies demonstrated that the CDs-loaded films effectively protected green apples from UV-induced damage and significantly extended the shelf life of strawberries, outperforming commercial polyethylene (PE) film. All these results highlight the potential of broccoli leaf-derived CDs as effective nanofillers for the fabrication of multifunctional chitosan/gelatin-based food packaging films.
