Abstract
Abstract
Bio-derived materials could play a major role in future supportable green and health technologies. Nontraditional materials such as proteins and biopolymers are observed for their probable use in the fabrication of bioplastics for packaging. In the present work, novel ternary composite films of chitosan (CS), polyvinyl alcohol (PVA), with different ratios of natural egg white (EW) and glycerol as a plasticizer, were fabricated by solution casting technique. The synthesized ternary composite films were characterized by UV–Vis absorption spectra, Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. The hydrophobicity of as-synthesized samples was confirmed by contact angle measurement. The microbiological screening analysis was established against bacteria viz. Pseudomonas sp., Bacillus subtilis and Staphylococcus aureus bacteria. The attained results denoted that the film might be an appropriate applicant for food packaging applications.
