Characterization A Novel Antimicrobial Nano Composite Edible Film Based on Salvia Macrosiphon

Abstract

This work aimed to develop a nano edible antimicrobial coating based on Salvia macrosiphon seed mucilage (SSM) and nanoclay, incorporated with glycerol to evaluate its physical properties. Upon addition of 2% nanoclay physical and mechanical properties were considerably improved and the composite films showed the lowest water vapor permeability (WVP), as well as highest elongation at break and tensile strength, which makes these films great alternatives for food packaging. While E. coli and S. aureus were significantly inhibited by this antimicrobial films. Results indicated that this novel antimicrobial edible film could have great potential for responsive packaging applications.
