Abstract

Kinetic analyses of death of Escherichia coli with microwaves in a tubular flow reactor were done by using the frequency factor - activation energy and activation entropy - activation enthalpy compensation relations. There was no actual isokinetic temperature for the death of E. coli, implying that the mechanisms of the death were different both in the microwave tubular flow reactor under varying experimental conditions and also in the typical constant temperature water bath. Although the death mechanisms appeared to be changing with the experimental conditions, the results implied that the compensation relations can be used in the design of the microwave pasteurization reactors.
