A research team has turned underused rapeseed-processing residues into a biodegradable active film designed to protect fresh food while reducing reliance on petroleum-based packaging. The material combines chitosan (CS) with phenolic extracts from rapeseed cake, flowers, stems, and leaves, together with biosynthesized silver nanoparticles (AgNPs). This combination strengthens the film, improves resistance to water, oxygen, and UV light, and adds antioxidant and antimicrobial activity.
