Milk viable aerobes and S. thermophilus inactivation have been accessed by Sun et al. According to the authors the observed results demonstrated that ohmic heating causes higher microbial death than the conventional heating process. In this study, the final microbial count and the calculated D values for ohmic heating were significantly lower than those acquired from conventional heating, under the same temperature history conditions.Therefore, it was pointed that ohmic heating caused a thermal lethal effect and an additional non-thermal lethal effect on the studied microorganisms. According to Sun et al. the inactivation effect of electricity is significant compared to that of heat and was shown to be related to the electrical voltage and frequency.
