Electrical Sterilization of Juice by Discharged HV Impulse Waveform

Hee Kyu Lee


In the sterilization system by using HV impulse waveform, apple juice was sterilized with HV discharged oscillatory decay waveform. The optimal condition of impulse waveform for electrical sterilization has presented the excellent condition at 40kV cmˉ1, 4mH and over. The characteristics of this waveform shows oscillatory decay waveform with multiple pulses. And this impulse waveform was more effective to kill S. Cervisiae than exponential decay waveform. S. Cervisiae to become musty and sour for apple juice was used as the sample. This apple juice has good effect of electrical sterilization because of higher conductivity than water. Therefore this experiment can be treated sterilization without loss of vitamin C and original taste or perfume to apple juice. As a result, it is found that apple juice can be sterilized on 40kVcmˉ1, 4mH and over by using our designed HV impulse sterilizer.
