The antimicrobial properties of two disparate bio-based coating additives were evaluated in a polyvinyl alcohol (PVA) food packaging coating for antimicrobial activity. Chitosan, a shrimp and crustacean shell derived polysaccharide, and an antimicrobial peptide were evaluated in a dissolvable food package coating for reductions in microbial growth after contacting agar patties serving as food simulants. Where the antimicrobial components of...
