Overview

Experimental analysis demonstrates quercetin-loaded films improve shelf life of fish, suggesting viable alternatives to traditional packaging materials.

Key Points

  • The PLA/chitosan/quercetin film showed a 98.2% ABTS radical scavenging rate, indicating strong antioxidant properties.
  • Inhibition rates against E. coli and S. aureus were 87.60% and 80.45%, demonstrating effective antimicrobial performance.
  • Shelf life testing revealed the film extended fish freshness by 2 days compared to traditional polyethylene packaging.
  • The composite film's color change served as a significant indicator of fish freshness, enhancing intelligent monitoring.
