Pulsed Electric Field Technology in Food Processing Industry-A Review

Pulsed electric field (PEF) processing is a non-thermal method of food preservation. The basic principle of the PEF technology is the application of short pulses of high electric fields with duration of micro seconds micro- to milliseconds and intensity in the order of 10- 80 kV/cm. In this paper application of PEF in different food processing industries and the effect of PEF on microorganisms, enzymes, proteins, fats and emulsions, pigments are reviewed.
