） Abstract： Liquid food abnormal breakdown is one of pulsed electric field sterilization technique technological bottlenecks
Breakdown characteristics of in-depth study of liquid food under the action of the pulse voltage and exploring the breakdown mechanism are very important to effectively solve the technological bottleneck
In order to study the influence of various factors on breakdown characteristics of liquid food under pulse electric voltage, the authors built experimental platform for the study on the breakdown characteristics, the breakdown characteristics of water、orange juice and beer this three kinds of liquid food were studied in this experiment platform, studied respectively the pressure, flow velocity and temperature on the effects of breakdown voltage
The results show that under the action of the pulse voltage, three kinds of liquid food breakdown voltage increased with the liquid pressure increased, with the increase of liquid flow velocity increased, increased with the increase of the temperature of the liquid
In the factors of pressure、flow velocity and temperature, pressure is the most prominent effect on breakdown voltage of liquid food under the action of pulse voltage, followed by the influence of flow velocity, the last is the influence of temperature
Therefore, to eliminate or suppress abnormal breakdown of liquid food in the pulsed electric field sterilization should mainly consider two aspects from the pressure and flow velocity
