Effect of L-arginine ethyl ester of lauryl mono-hydrochloride (LAE) on the physical and antibacterial properties of zein bio compsit films containing oleic acid

Lauryl Arginine Ethyl Ester mono-hydrochloride (LAE) is a relatively new preservative in the food industry to control the growth of pathogenic microorganisms. The aim of this work was to characterize of zein film containing 5 and 10% LAE at the presence of oleic acid as a plasticizer. The results of this studied showed that incorporation of 5 and 10% LAE water vapor permeability of zein film at 90% relative humidity in compare to control film decreased 34 and 48%, respectively. With increasing of concentration of LAE in zein film solution Young’s modulus, percent elongation at break and tensile strength were reduced. And also, water solubility of zein film in present of LAE not significantly increased was observed (p
