Summary

A predictive model was used to estimate the effect of pH (4.7-7.5), temperature (3-35 deg C) and salt concentration (0-8%) on the growth of Listeria monocytogenes. Descriptors such as duration and phase of latency, duration of exponential growth phase and generation time were calculated. Polynomial models were developed on the basis of these results and validated for different dairy products, including pasteurized milk, UHT milk, cream, butter and camembert cheese.
