Synthesis of Cardamom loaded Guar Gum and Gelatin composites, their characterization and antibacterial study

Abstract

Antimicrobial activity in leaf extract of cardamom (Elettaria cardamomum) against Human pathogenic bacteria, E.coli. Extract showed a broad spectrum of significant antibacterial activity by producing a clear zone of inhibition against E.coli. The clear zone of inhibition in bacterial samples produced by cardamom extract. Polymer blends based on Gelatin and Guar Gum were prepared by solution casting method. Glycerol was added as a plasticizer with different ratios (5, 10 and 20 %). The physical properties of the plasticized polymer blends were investigated in terms of swelling percent (%). The structure of plasticized polymer blends was characterized by Fourier Transform Infrared Spectroscopy. The obtained results showed that obtained as plasticizer improved the swell ability and expansion study of polymer blend.
