Abstract
Listeria monocytogenes (L. monocytogenes) resuspended in several type of milk and other solutions was heated at 60°C. Decimal reduction time (D value) was calculated from the survival curve of L. monocytogenes. These D value of survival phase of L. monocytogenes was longer than that of log phase of L. monocytogenes. And also, preheating of the solution resuspended survival phase of organisms at 48°C for an hour increased D value of L. monocytogenes, especially in the case of raw milk than the case of sterilized milk.
