The PEF method, with extremely short time (µs-msOM) of sterilization, consumes very low power, being only one thousandth of the total power consumed in the high temperature method, and far less than the power cost in the ultrasonic wave, the microwave or others3]. Besides, in the PEF method, it is the high voltage other than the current used to sterilize, thus in the whole course, the temperature rarely rises and so the defect of high temperature can be avoided. Generally speaking, in the PEF method, the rise of the temperature is less than 5℃ and the effect of sterilization is obvious, if the condition of sterilization well controlled. The sterilizing rate can get quite close to the commercial requirement and this method can be best fit the food most sensitive to high temperature, since PEF barely affect the quality of food
