Green composite film for food packaging applications

In this study, isolation and characterization of nano cellulose from peanut shell was carried out. A new biodegradable antimicrobial film was developed using chitosan, zero valent iron (zvi) nanoparticle and nanocellulose. Nano cellulose got from peanut shells was utilized as filler and iron oxide as hostile to microbial reinforcer for chitosan. Another arrangement of green composite film was additionally arranged by surface alteration of nano cellulose and tried for antimicrobial property. The two films were described utilizing Fourier transform infrared (FTIR) spectroscope, X-ray diffraction (XRD) technique, Scanning electron microscope (SEM), thermo gravimetric analysis (TGA) and contact angle estimations. Antibacterial activity of the prepared green composite films was directed against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 by agar dispersion strategy. The outcomes demonstrated that Peanut shell waste could turn into a suitable wellspring of monetarily significant nano cellulose. It was likewise discovered that cellulose got from Peanut shells improved mechanical properties like tensile and impact tests. The high degradation temperature of nano composite showed prevalent thermal stability. All the characterisation underlined that carboxy methylated nanocellulose fortified compososite film displayed more sensitivity and can be viably utilized as packaging material to improve the shell life of food materials.
