Gelatin and Carboxymethyl Chitosan Edible Coating Incorporated with Carvacrol: Development and Applicationin Strawberries

This study developed antimicrobial composite coatings from gelatin (GL) and car- boxymethyl chitosan (CMCS) functionalized with carvacrol (CA) as a natural alternative for the preservation of strawberries. Films incorporated with 0%, 1.5%, and 3% CA were characterized by their physical, mechanical, and structural properties. The addition of CA significantly improved opacity, tensile strength, elongation-at-break, and thickness, while reducing water vapor permeability, moisture content, and...
