Tóm tắt

This study developed a nanoantioxidant-based active food packaging film with antibacterial activity, low cytotoxicity, and potential for food preservation. Ag-doped ZnO nanoparticles (ZnO.Ag NPs) were synthesized with antioxidant and UV-shielding properties and loaded with catechin (Cat) to enhance biological activity. These nanoantioxidants were incorporated into chitosan/poly(vinyl alcohol) (CS/PVA) films (CP.(ZAC)) at varying concentrations. Adding ZnO.Ag@Cat reduced the water contact angle (89° to 78°) and water vapor permeability (121 × 10
