Abstract
Worldwide, banana waste totals about 114 million tons each year, and the peels are rich in bioactive compounds with strong antioxidant and antimicrobial properties. Rather than being simple by-products, they represent a promising circular economy resource for reducing environmental burdens. In this study, banana peel extracts were incorporated into a chitosan matrix to develop functional active food packaging films. As the extract content increased, the total phenolic content and DPPH radical scavenging activity rose, leading to significantly enhanced antioxidant properties. Furthermore, the films maintained their antibacterial activity against E. coli and S. epidermidis even after composite formation and carnauba wax coating. The hydrophobicity imparted by the carnauba wax coating effectively reduced surface contamination. These findings demonstrate the potential to upcycle agri-food waste into eco-friendly packaging materials, thereby improving storage stability and shelf life of food products.
