Thermal inactivation kinetics were evaluated in batch and continuous flow systems using phosphate buffer between 99 and 107°C for Bacillus cereus T and 128.5 and 139°C for Bacillus stearothermoohilus ATCC 12980 spores. z D ‐Values for B. cereus spores in batch aid continuous flow systems were not significantly different; the continuous flow system was more lethal than the batch system. z D ‐Values obtained using B. stearothermophilus spores in batch and continuous flow systems were different; the batch system was more lethal than the continuous flow system. Thus, use of batch generated data to predict or design continuous flow processes may not be accurate.
