Technical Abstract: A microwave heating system was developed for inactivating Listeria monocytogenes in ready-to-eat meats. Frankfurters, inoculated and vacuum-sealed in plastic packages, were subjected to heating, with the package surface temperature increased to and maintained at three temperature set points for different periods of time. The surface temperature of frankfurter packages increased linearly with the heating time until it reached a set point. The observed rate of bacterial inactivation was 0.41, 0.65, and 0.94 log(CFU/pk) per min at the surface temperature of 65, 75, or 85C. This study demonstrated the feasibility of a PID-controlled microwave heating process for in-package pasteurization of frankfurters.
