Abstract: The high-Intensity pulsed electric fields ( PEF) non-heat treatment technology is becoming one of most active technologies that study bacteria killing due to its short handling time, slight temperature rise, low power consumption and obvious effect etc. And in the side of extracting functional ingredients and keeping active, it shows a good application prospect. This paper stresses the processing principle, the processing procedure and safety control of this technology.

Key words: high-Intensity pulsed electric fields (PEF), non-heat treatment technology, processing principle, process-ing procedure, safety control
