Characterization and antimicrobial analysis of chitosan composite biodegradable films with addition of lemon grass essential oil

The increasing demand in food safety, quality, convenience and environmental concerns associated with the handling of plastic waste has emphasized the importance in developing biodegradable and edible films from natural polymers, such as chitosan. Starch-based film is considered an economical materi...
