The aim of this study was to examine the efficacy of lauric arginate (LAE, 1000 ppm – 3000 ppm) as an assisting tool to reduce starved Listeria monocytogenes population in ground beef following sous-vide processing at different temperatures (55–62.5 °C). Ground beef mixed with LAE was vacuum sealed and a laboratory water bath was used for sous-vide cooking. Loglinear and Weibull models were fit to the survival microbial population and the D and Z-values were determined at 55–62.5 °C. Calculated D-values ranged from 33.62 to 3.22 min at temperature 55–62.5 °C. LAE at higher concentration is an effective antimicrobial to …
