Accelerated inactivation of Geobacillus stearothermophilus spores by ohmic heating

► Inactivation kinetics of bacterial spores was determined for conventional and ohmic heating. ► The setup ensured identical thermal histories between ohmic and conventional treatments. ► Ohmic heating accelerates inactivation kinetics of spores compared to conventional heating. ► This result could enable reduced process time and improve the quality of sterile products.
