Development of a Phycocyanin–Copper-Loaded Gelatin–Chitosan Active Forming Film Solution and Its Application in Fruit Quality Preservation
Phycocyanin–Cu2+-loaded gelatin–chitosan composite films (Gel/Cu@PC/Ch) were developed as active packaging materials to address the postharvest deterioration of fresh produce. A series of composite films with varying chitosan (Ch) concentrations (0.1%, 0.5%, 1%, 5%, w/v) were systematically fabricated and characterized...
