The study of Low Temperature Pasteurization System using High Voltage High Current Pulse Electric Field
초록
The non-thermal pasteurization of foods using High Voltage High Current Pulsed Electric Fields (HVHC-PEF) is a promising technology and a sound complement or replacement to traditional thermal pasteurization. The conventional thermal method also inactivates bacteria and other microorganisms harmful to humans, but degrades natural color, flavor, texture and nutrients. At this point, a nonthermal pasteurization technique, HVPEF is thought to be a new processing technique which is able to produce a good quality foods nutritional as well as sensuous. In this paper, the system for HVHC-PEF pasteurization is presented. It use square wave pulse instead of exponential ones. So, power rating of system is reduced considerably. Design considerations for 20kV 500A class equipment are analyzed and experimental results are discussed.
