COMBINED ANTIMICROBIAL EFFECT OF THYMOL AND SODIUM LACTATE AGAINST LISTERIA MONOCYTOGENES AND SALMONELLA TYPHIMURIUM IN FISH PATTY

Abstract

The purpose of this study was to evaluate the antimicrobial efficacy of the combinations of thymol (0.1 w/w) and sodium lactate (1 and 2% v/w) against Listeria monocytogenes and Salmonella Typhimurium in fish patty samples stored at 4C for 5 days. Treatment with the combination of 0.1% thymol + 2% sodium lactate did not show a significant inhibition on the L. monocytogenes when compared with the sample treated with 2% sodium lactate alone. However, treatment of fish patty with the combination of 0.1% thymol + 2% sodium lactate showed a synergistic effect on Salmonella Typhimurium on days 3 and 5 of storage.
