Bilayer Polylactic Acid and Chitosan/Gelatin Film Containing Epigallocatechin Gallate Prepared through Solvent Casting and Electrospinning: Properties, Bioactivities and Release Kinetics

This paper presents the development of biodegradable and environmentally friendly packaging films. Active packaging bilayer films were prepared by combining chitosan-fish gelatin (CS-FG) with epigallocatechin-3-gallate (EGCG) at varying concentrations on the top layer of polylactic acid (PLA) film v...

Description
Summary:This paper presents the development of biodegradable and environmentally friendly packaging films. Active packaging bilayer films were prepared by combining chitosan-fish gelatin (CS-FG) with epigallocatechin-3-gallate (EGCG) at varying concentrations on the top layer of polylactic acid (PLA) film via solvent casting (SC-films) or electrospinning (ES-films) technique. Incorporation of EGCG (0.5–2%) in films significantly increased tensile strength, film thickness, water vapor barrier properties, seal strength and antioxidant activities (P
