Comparative investigation of the antimicrobial effectiveness of cinnamaldehyde incorporated soy protein isolate (SC) films and cinnamaldehyde-SPI coated polypropylene/polypropylene (SC/OPP/PE) films were investigated. Minimum inhibitory and minimum bactericidal concentrations (MIC, MBC) of cinnamaldehyde against Escherichia coli, Salmonella typhymurium, Bacillus cereus, and Enterobacter sakazakii were investigated. Addition of cinnamaldehyde into SPI increased the tensile strength, whereas decreased the water vapor permeability and elongation at film breakage. Size of antimicrobial zone in disc diffusion test was decreased in cast films and no diffusion was found in coated OPP/PE films but concentration dependently deduction of total microbial count was found when three different sprouts (radish, broccoli, alfalfa) were packed with CASPI-OPP/PE film by pouch type. It indicated that cinnamaldehyde with low concentration could diffuse to environment and could be effective on antimicrobial for preservation of food packaging.
