A green, chemical crosslinker-ternary macromolecular film from soy protein, Camellia waste, and carrageenan via Maillard reaction for food preservation.
Bio-based packaging films are promising alternatives to petroleum-based plastics, but their application is limited by chemical crosslinkers, high feedstock costs, and performance-sustainability trade-offs. Here, a crosslinker-free ternary film (SCC) was fabricated from soy protein isolate, Camellia oleifera cake extrac...
