Versatile corn starch-based sustainable food packaging with enhanced antimicrobial activity and preservative properties

Biodegradable active packaging has garnered significant research interest owing to growing concerns over plastic pollution and food safety. However, current food packaging materials still suffer from drawbacks such as complex synthesis processes, high production costs, and inadequate safety performance in terms of antimicrobial resistance and biodegradability. Typically, their performance in preserving fresh food is also inferior to that of plastics. Herein, a versatile corn starch-based sustainable food packaging (DC) was proposed, utilizing natural corn starch (CS) and carboxymethyl chitosan (CMCS) as raw materials. The focus was on evaluating the mechanical properties, antioxidant properties, and…
