Pereira et al. have reported lower D and z values for the inactivation of E. coli and B. licheniformis when submitted to ohmic heating. In this research, comparing conventional against ohmic heating, the thermal history of the samples analyzed was adjusted to match. The D values observed for E. coli at 65 C were 3.5 0.2 and 0.86 min for conventional and ohmic process respectively. The z values were also reported as 23.1 and 8.4 C respectively. The observed results indicate that the electric current may have affected the microbial death rate. Similar observations were obtained in the same study for the spore inactivation of B. licheniformis. Considering both microorganisms strain, ohmic heating presented a lower D value. This fact indicates that an additional nonthermal lethal effect occurred under ohmic heating, due to the presence and effects of the electric current over vegetative cells of E. coli and bacterial spores of B. licheniformis
