Title: Predicting inactivation of Salmonella senftenberg by pulsed electric fields
Abstract: Pulsed electric field inactivation of Salmonella senftenberg suspended in McIlvaine buffer of pH 7 and conductivity 2 mS/cm was investigated. In this study, square wave waveform pulses were used. After the same treatment time, inactivation of S. senftenberg depended neither on pulse width (1–15 μs) nor frequency of treatment (1–5 Hz). Survivor curves of S. senftenberg at different electric field strengths did not follow first-order kinetics. These survival curves were described by the log-logistic model proposed by Cole et al. [Cole, M. B., Davies, K. W., Munro, G., Holyoak, C. D., and Kilsby, D. C. (1993). A vitalistic model to describe the thermal inactivation of Listeria monocytogenes. Journal of Industrial Microbiology, 12, 232–239]. Comparison of measured and estimated values showed that this model accurately described the inactivation of S. senftenberg by high electric field pulses in the range of 12–28 kV/cm.
