Abstract
The effectiveness of rosemary and thyme oils as antimicrobial agents in mozzarella cheese against Listeria monocytogenes lactic acid bacteria LAB and total aerobic bacteria TAB was evaluated In low fat cheese rosemary and thyme oils inhibited L monocytogenes by 05 and 10 log CFU/g respectively and by 17 log CFU/g in combination on day 20 at 4°C Combination of rosemary and thyme oils inhibited growth of L monocytogenes and LAB in low fat cheese but not in full fat cheese Rosemary and thyme oils with sodium diacetate were more effective for inhibition of L monocytogenes than oil alone Essential oils have potential applications for inhibition of indigenous microorganisms in low fat food products and for controlling growth of L monocytogenes after postprocessing contamination The oils also showed potential for inhibition of microorganisms in full fat products in combination with sodium diacetate
