Preparation and charaterization of PVA / cellulose nanocrystals / ZNO nanocomposite as potential for thin film in chili fresh fruit packaging application

The focus of the thesis is on the production and examination of thin films made of polyvinyl alcohol (PVA), cellulose nanocrystals (CNC), and zinc oxide (ZnO), with an eye towards their potential application in food packaging. The research's characterization phase includes a comprehensive investigation of the physical and chemical properties of the resulting thin films. A material endurance can be assessed by examining its tensile strength, flexibility, weight loss, and x-ray diffraction results, among other mechanical properties. Consideration of gas and moisture permeability characteristics is crucial for food packaging materials. By shedding light on these characteristics, the study intends to significantly advance the area of sustainable packaging. Packaging food items requires attention to both mechanical and antimicrobial requirements to ensure continued quality and safety. An eco-friendly and effective replacement for food packaging is what we are aiming for. By incorporating antimicrobial properties into the packaging material, we can prevent the growth of harmful bacteria and extend the shelf life of food products. Additionally, the study will also evaluate the environmental impact of the packaging materials to ensure they are truly sustainable and contribute to reducing waste in the long run. A research study found that PVA, CNC, and ZnO were the most effective in keeping fresh chilies fresh for 20 days. In order to decrease plastic waste from packaged foods with a lengthy shelf life, this study proposes a long-term solution.
