Analysis and Design of Pulsed Electric Fields pasteurization Mechanism Test
Use of pulsed electric fields (PEF) for pasteurization of liquid foods is one of the more promising cold-pasteurization methods. This study used fluorescent pseudomonas as target cell. It was operated 180 s in the PEF of 30 kV, 50 Hz. It was found that the cell walls of the treated bacteria were broken, the irreversible perforations were formed on the cell membrane. As a result, the cytoplasm and nucleolus substances flow away and the cell died. This paper revealed that the pulsed electric fields sterilization technique could sterilize effectively and can maintain the foods quality and reduce the sterilization cost in maximum.
