Biodegradable and antibacterial edible films based on egg yolk granules/gelatin/CMC with e-poly-l-lysine: Application in fresh chicken meat preservation.

Novel biodegradable and antibacterial edible films were fabricated by incorporating E-poly-l-lysine (EPL) into egg yolk granules, gelatin, and sodium carboxymethyl cellulose matrices. With increasing EPL concentration (0.3-0.
