This study was conducted to develop a model to describe the effect of antimicrobials [potassium sorbate (PS),potassium lactate (PL), and combined PL and sodium diacetate (SDA, PLSDA)] on the growth parameters of Listeriamonocytogenes such as specific growth rate (SGR) and lag phase periods (LT) in air-dried raw sausages as a function ofstorage temperature (4, 10, 16, and 25oC). Results showed that the SGR of L. monocytogenes was dependent on the storagetemperature and level of antimicrobials used. The most effective treatment was the 4% PLSDA, followed by the 2% PLSDAand 4% PL and 0.2% PS exhibited the least antimicrobial effect. Increased growth rates were observed with increasing storagetemperatures from 4 to 25oC. The growth data were fitted with a Gompertz equation to determine the SGR and LT of the L.monocytogenes. Six polynomial models were developed for the SGR and LT to evaluate the effect of PS (0.1, 0.2%) and PL(2, 4%) alone and PLSDA (2, 4%) on the growth kinetics of L. monocytogenes from 4 to 25oC.
