Comparative analysis of blend and bilayer films based on chitosan and gelatin enriched with LAE (lauroyl arginate ethyl) with antimicrobial activity for food packaging applications / Haghighi, Hossein; De Leo, Riccardo; Bedin, Elisa; Pfeifer, Frank; Siesler, Heinz Wilhelm; Pulvirenti, Andrea. - In: FOOD PACKAGING AND SHELF LIFE. - ISSN 2214-2894. - 19:(2019), pp. 31-39.

Abstract:
Blend and bilayer bio-based active films were developed by solvent casting technique, using chitosan (CS) and
gelatin (GL) as biopolymers, glycerol as a plasticizer and lauroyl arginate ethyl (LAE) as an antimicrobial
compound. Blend films had higher tensile strength and elastic modulus and lower water vapor permeability than
bilayer films (p < 0.05). Bilayer films demonstrated as effective barriers against UV light and showed lower
transparency values (p < 0.05). FT-IR spectra indicated that interactions existed between CS and GL due to
electrostatic interactions and hydrogen bond formation. However, the addition of LAE did not interfere in the
network structure. Active films incorporated with LAE (0.1%, v/v) inhibited the growth of Listeria monocytogenes,
Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. This study highlighted the development
of blend and bilayer bio-based active films based on CS and GL enriched with LAE for food packaging
applications with improved physical, mechanical, barrier and antimicrobial properties.o
