Synergistic effects of fresh garlic juice in cellulose based antimicrobial food packaging film

Abstract

This article presented a novel food packaging film made from cellulose nanofibers (CNFs), raw garlic juice and glycerol. The film was made tough, strong, and barrier-resistant by treating the CNFs with glycerol and citric acid vapor, which performed as a plasticizer and cross-linking agent, respectively. Garlic juice was added as the antibacterial agent. The as-produced films exhibited 529, 47, and 59% higher extensibility, moisture resistance, and water vapor barrier, respectively than the pristine CNF film. The film also showed excellent antifungal and antibacterial resistance.
