Abstract: An improvement to existed methods of microbial spore inactivation is presented in this paper. A treatment chamber was designed to hold elevated temperatures (above 100 °C) and pressure in the range of (3 atm). The innovative thermal assisted pulsed electric fields (PEF-ATS) processing was applied to inactivate Geobacillus sterothermophilus ATCC 10149 spores suspended in simulated milk ultrafiltrate (SMUF) of 50% (wt/wt) concentration. G. stearothermophilus spores are extremely resistant to high temperature and…
