摘要：

Biomass-based composite packaging materials loaded with functional fillers have good application prospects in food preservation and freshness detection. Self-healing hydrogel packaging films based on nanocellulose (CNF), polyvinyl alcohol (PVA), and ZIF-8 embedded with curcumin (Cur@ZIF-8) were developed in this study. The synthesis of Cur@ZIF-8 was demonstrated by characterization experiments. The addition of Cur@ZIF-8 enhanced the water vapor barrier property, tensile strength, and elongation at break of hydrogel films by 49.2 %, 193.5 %, and 172.9 %, respectively, and endowed them with excellent antimicrobial, antioxidant, and ammonia sensitivity. In packaging tests with fish, hydrogel films loaded with Cur@ZIF-8 inhibited spoilage and microbial growth to extend the shelf life of fish to 9 days, and the color change of hydrogel films allowed for real-time monitoring of fish freshness. This study provided a new solution for smart packaging materials with dual functions of preservation and freshness indication.
