SYNTHESIS AND PROPERTIES OF DEGRADABLE BIOFILMS FROM RAW BANANA POWDER TO GROW NANOCOMPOSITESIN THE FOOD PACKAGING APPLICATIONS

Abstract

Silver nanoparticles were developed using aqueous extract of Citrus limetta leafas a reducing as well as capping agents, and Silver Nitrate as a precursor. Raw banana powder was used to develop starch-based nanocomposites films containing glycerol as plasticizers incorporated with silver nanoparticlesat different concentrations via solution casting method. Themain objectives of this study were to improve the properties such as mechanical, thermal and physical properties of starch nanocomposite films incorporated with silver nanoparticles containing glycerol as plasticizer. The physicochemical properties of the film were characterized.In general, a high concentration of silver nanoparticles in the film could increase the tensile strength,reduce the water vapor permeability and water solubility and also antibacterial activity.
