Preparation and characterization of PVA /cellulose nanocrystals/ e-polylysine nanocomposite as potential food packaging application

The thesis revolves around the synthesis and analysis of Polyvinyl Alcohol (PVA) Cellulose Nanocrystals (CNC) ɛ-Polylysine thin films, targeting their potential application in packaging food. The process of preparing these thin films involves solvent casting method, ensuring the proper incorporation of cellulose nanocrystals and polylysine into the PVA matrix. The characterization aspect of the research involves a comprehensive investigation into the physical and chemical properties of the resulting thin films. Mechanical properties, such as tensile strength and flexibility, x-ray diffraction analysis are examined to assess the material's durability. While for fresh fruit testing such as weight loss, brix analyzer, texture analyzer and pH are examined to know the freshness of chili before and after wrapped with the thin film. By shedding light on these characteristics, the research aims to contribute valuable insights to the field of sustainable packaging. The goal is to provide an effective and eco-friendly alternative for food packaging applications, addressing both the mechanical and antimicrobial requirements essential for maintaining the quality and safety of packaged food products.
