Potential Use of Selected Natural Anti-Microbials to Control <i>Listeria monocytogenes</i> in Vacuum Packed Beef Burgers and Their Impact on Quality Attributes.

ABSTRACT: This study assessed the potential for natural anti-microbials to control Listeria monocytogenes in vacuum packed beef burgers. Minimum inhibitory and bactericidal concentration (MIC and MBC) results for natural anti-microbials (carvacrol; essential oils of thyme, rosemary, clove and cinnamon; hop extract; cranberry extract; cranberry pomace; propolis extract; and chitosan sourced from both shrimp and mushroom) were used to select agents (n = 6) showing the most promise against L. monocytogenes. These agents, including chitosan from shrimp and mushroom (a novel source), and cranberry extract, were then tested against L. monocytogenes in vacuum packed beef burgers during chilled storage (3 ± 1 °C, 16 days). Following storage (16 d), the number of L. monocytogenes
