Biodegradable, Antimicrobial and Antioxidant Biofilm for Active Packaging Based on Extracted Gelatin and Lignocelluloses Biowastes

Abstract

Blending of lignocellulosic fibers from Citrus trees trimming wastes and extracted gelatin (EG) was examined as low cost biobased active biofilm packaging materials imminent substitution for toxic and non-degradable petrochemical polymers. Citrus lignocellulosic fibers (CLCF) are rich with many antioxidants, biocompatible and have high safety profiles. EG is an extracted biopolymer from white leather shavings (WLS) as leather industry wastes after alkaline hydrolysis. Both wastes were an adaptation for safe and green packaging requirements. The resulting biofilms were described using Fourier transform Infrared (FT-IR) spectroscopy, thermal analysis (TGA and DTGA), scanning electron microscope (SEM), biodegradability, antioxidant and antimicrobial. The properties of some characteristics of blends biofilms as far as mechanical, thermal properties have been discussed as biodegradable package films. In context, the prepared biofilms were characteristic with antimicrobial, antioxidant and biodegradability with adequate different mechanical and permeability properties which suitable to different packaging applications.
