Exploration of Multifunctional Properties of Piper betel Leaves Extract Incorporated Polyvinyl Alcohol-Oxidized Maize Starch Blend Films for Active Packaging Applications

This study explains the development of eco-friendly polyvinyl alcohol (PVA)/oxidized maize starch (OMS)/Betel leaves extract (BLE) blend films by employing a cost effective technique. The influence BLE on structural, Thermal, Mechanical, Morphological, Optical, Antibacterial and Antioxidant properties PVA/OMS were investigated successfully applying various characterization techniques. hydrogen bonding interaction among components led to enhance thermal stability, miscibility, mechanical properties, smooth surface morphology UV blocking films. addition enormously improved antibacterial antioxidant Moreover, obtained hydrophilic, water soluble biodegradable in nature. With regard barrier vapour transmission rate oxygen permeability enhanced after doping BLE. These experimental outcomes suggest that containing can be used for expansion active packaging materials.Graphic Abstract
