SOY PROTEIN FILM REINFORCED WITH SILVER NANOPARTICLE ANCHORED CARBON DOTS AND CHITIN NANOWHISKER FOR PACKAGING

Abstract

This study demonstrates a great strategy for developing active biopolymer film from soy protein isolate (SPI) with silver nanoparticles anchored carbon dots and chitin nanowhiskher. In this work, we have adopted an environment-friendly method where carbon dot (CD) prepared from soy protein isolate is used to prepare AgNPs. AgNP (1% wt.) and different concentrations of chitin nanowhisker (CNW) (2- 10% wt.) were added to soy protein isolate to fabricate nanocomposite films. The prepared SPI based bionanocomposite films were characterized by FTIR, XRD and SEM. Commercial production of such SPI films would revolutionize the food packaging industry given its health benefits and cost effectiveness.
