Thermal characterization of Bacillus subtilis endospores and a comparative study of their resistance to high temperature pulsed electric fields (HTPEF) and thermal-only treatments
B. subtilis endospores were more heat tolerant in milk than in water. z-values for B. subtilis spores in milk and water were not significantly different. HTPEF inactivated more than 4.5 log10 cycles of B. subtilis spores. HTPEF offered no advantage to heat using the conditions applied.
