Research Status of High-Intensity Pulsed Electric Field (PEF) Equipment and its Application on Food Processing

Due to short treatment time, the quality change of food caused by heat can be reduced, high-intensity pulsed electric field (PEF) has been widely used, especially in food industry. PEF system consists of PEF generator, treatment chamber, pump, cooling coil, container and monitoring system. The research status of PEF generator, pulses waveforms, treatment chamber and electrodes were discussed. And the application of PEF on food processing was summarized.
