Microbial inactivation kinetic models are needed to predict treatment dosage in food pasteurization processes. In this study, we determined inactivation kinetic models of Salmonella dublin in skim milk with a co-field flow high voltage pulsed electric field (PEF) treatment system. Electric field strength of 15-40 kV/cm, treatment time of 12-127 mu s, medium temperatures of 10-50C were tested. A new inactivation kinetic model that combines the effect of treatment time to electric field strength or medium temperature was developed.
