Résumé

Low-molecular-weight polylactic acid (LMW-PLA) and lactic acid were used to inhibit growth of Listeria monocytogenes Scott A on vacuum-packaged beef. Nisin was also used simultaneously as an additional hurdle to the growth of this pathogen. These treatments combined with vacuum-packaging and refrigeration temperature, succeeded in inhibiting growth of L. monocytogenes during storage up to 42 days. At the end of 42 days, the numbers of L. monocytogenes Scott A remaining viable on these samples were 1.21, 0.36, 2.21, 0.84, and 0.89 log(10) CFU/m2, respectively.
