Preparation and Characterization of Chitosan Nanocomposite Films in Different Solvent and its Antimicrobial Activity.

ABSTRACT

In this present research programme,chitosan nanocomposites were prepared by using C 30B which is an organomodified nanoclay by solvent casting method and were characterized by FTIR, XRD and SEM. Different chitosan films like acetate, formate, citrate, lactate and ascorbate were also prepared by taking different types of solvent like acetic acid, formic acid, citric acid, lactic acid and ascorbic acid respectively. The properties like thickness, density and transparency of those films were studied. The antimicrobial activity of those films were also investigated against various food borne pathogens like S.aureus, B.cereus, S.typhimurium and E.coli and it was found that all chitosan citrate films showed higher inhibitory activity against all the types of pathogens.
