ABSTRACT
Energy and mass balances for the continuous single pass and recirculation mode of a pulsed electric field (PEF) installation were analyzed. The importance of the electric field and frequency pulses in food temperature increases was also discussed. Inoculation studies with Bacillus subtilis var. niger, ATCC 9372, in simulated milk ultrafiltrate (SMUF) were carried out in a continuous single pass operation to predict the results of recirculation. Good agreement between the experimental results with recirculation (total recirculation of the fluid leaving the PEF chamber) and the values predicted by the model were achieved.
