A Measuring Method of Liquid Food Conductivity Based on Pulse Response Measurement Method

Abstract:

The food conductivity is one of impact factors on pulsed electric field sterilization. Abnormal breakdown of high conductivity liquid is also one of the bottlenecks in pulsed electric field sterilization technology. The conductivity of liquid food should be accurate calculated for searching the mechanism of abnormal breakdown deeply. An accurate measuring method of conductivity of liquid food is proposed based on pulse response method. Conductivity can be calculated by data recorded from oscilloscope with electrical pulse treating on the conductance cell. This method can decrease the impact of stray capacitance and polarization phenomenon on measured results.
