Abstract: Quantifying the microbial inactivation during a thermal treatment is a main objective in the food industry in order to design a microbiologically safe process and to avoid fail-dangerous or, on the contrary, overly conservative heat processes. This work focuses on the effect of different heating regimes, i.e., with a heating rate of 0.15, 0.20, 0.40, 0.55, 0.82, and 1.64 degrees C/min, from 30 to 55 degrees C, on the (induced) heat resistance of Escherichia coli K12 MG1655. Dynamic inactivation experiments performed under realistic time-temperature conditions are used as a vehicle to validate pertinent modelling and microbial information originating from static inactivation experiments and comprehensive literature observations.
