Περίληψη: Active packaging materials with integrated antioxidant and antimicrobial functions offer an effective strategy for extending the shelf life of highly perishable aquatic foods. In this study, a multifunctional composite film was fabricated by incorporating natural deep eutectic solvent (NADES)-extracted propolis bioactives and two-dimensional ZIF-L nanocarriers into a poly(vinyl alcohol) (PVA) matrix. The synthesized ZIF-L exhibited a characteristic leaf-like morphology with an average particle size of 140 nm, facilitating its uniform dispersion within the polymer network. Structural analyses confirmed that ZIF-L and propolis extracts were successfully integrated into the PVA matrix through hydrogen bonding and physical interactions. The resulting PVAD/ZIF composite films displayed enhanced flexibility and improved UV-shielding properties while maintaining good transparency. The optimized PVAD/ZIF0.5 film exhibited the highest antioxidant activity with a DPPH radical scavenging rate of 70.2%, and showed strong antimicrobial activity against Staphylococcus aureus and Escherichia coli. Application tests demonstrated that oysters packaged with PVAD/ZIF0.5 maintained TVB-N values below 30 mg/100 g and a TVC of 5.80 log CFU/g after 10 days of refrigerated storage, whereas control samples exceeded spoilage limits. Furthermore, the PVAD/ZIF0.5 retained good mechanical integrity under high-humidity conditions, while Zn2+ migration remained well below the regulatory limit for food-contact materials. In addition, cytocompatibility assays showed high cell viability (96.28%) after 24 h incubation. These findings demonstrate that the PVAD/ZIF composite film is a promising biodegradable active packaging material for aquatic food preservation.
