چکیده
In this study we demonstrated the inactivation of E. coli, C. difficile, meshophilic bacteria and Salmonella spp. through Pulsed Electric Field (PEF) technology. First, a simulation using Finite Element Method Magnetics Mathematical Modeling was used to obtain electric field values be in electro-pasteurization tunnel. Then, practical tests were carried out by an industrial scale apparatus set with following parameters: pulse 20 s – 40 s, 40, 80 450 kV, radio frequency 350 kHz treadmill speed at 10 m/min. The results from shows complete elimination all microrganisms, thus proving that PEF technology significantly contributes food safety can on scale.

The objective of the present study was to evaluate the efficiency of pulsed electric field (PEF) against Escherichia coli contaminating the liquid whole egg (LWE). The samples of LWE were inoculated with the test bacteria and subsequently treated for 30 μs by the different number of pulses (20-180) of PEF (32.89 kV x cm). Application of PEF resulted in statistically significant reduction of the...
