| Description | This study evaluated the effect of sodium benzoate mixed with potassium sorbate (E 211 and E 202) and a commercially available preservative Defence JB on survival and growth of L. monocytogenes in nine types of ready-to-eat foods. In most tested foods, L. monocytogenes was unable to proliferate and its counts at the end of storage were significantly lower than those at the baseline after artificial inoculation irrespective of whether or not preservatives were added. The only exceptions were pasta salad and hardboiled eggs in mayonnaise where L. monocytogenes proliferated, again irrespective of added preservatives. Our results suggest that synergistic effects of intrinsic factors such as pH and aw with low storage temperatures plays a greater role in controlling L. monocytogenes growth than tested preservatives. |
