Development of an Active Crosslinked Nanocomposite Film Based on Gelatin-Ethyl Cellulose, Trans-Cinnamaldehyde, and Silver Nanoparticles for the Preservation of Sliced Meat.

ABSTRACT: This study aimed to develop a novel bioactive biobased packaging film combining gelatin (G) and ethyl cellulose (EC), cardanol and glycerol as plasticizers, trans-cinnamaldehyde (TCA) as a crosslinker/bioactive compound, and silver nanoparticles (AgNPs) as bioactive agents. The degree of crosslinking, mechanical and thermal properties, water solubility (WS), and water vapor permeability (WVP) of the films were analyzed. Molecular interactions within the film matrix were determined by FTIR spectroscopy. The G-EC film, in a 1:2 weight ratio, exhibited improved physicochemical properties compared to the pure G film, with a low WS (7.8%). The incorporation of TCA and AgNPs-to form bioactive nanocomposite films-improved the barrier and mechanical properties of the film (WS 0.33%, WVP 2.39 g·mm·
