Broccoli leaf-derived carbon dots reinforced chitosan/gelatin film as UV-blocking, antioxidant, and antibacterial films for food packaging

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.
