Paper: Development of carboxymethyl cellulose–chitosan based antibacterial films incorporating a Persicaria minor Huds. essential oil nanoemulsion
This study developed a potential antibacterial food packaging film using carboxymethyl cellulose (CMC)–chitosan (CS) infused with Persicaria minor essential oil nanoemulsion. Compared to coarse emulsions, the nanoemulsion showed smaller droplet size, better stability, and stronger antibacterial activity. Incorporating different concentrations (0–12% v/v) of nanoemulsion into the film improved flexibility and bioactivity.
The research found that 12% (v/v) nanoemulsion film exhibited optimal properties, including low moisture content, high antioxidant capacity, and strong antibacterial effects against E. coli and B. subtilis.
Overall, the findings highlight the potential of this bioactive packaging to help reduce foodborne pathogens and serve as an eco-friendly alternative to conventional plastics.
