Abstract: Determination of pork moisture content is of great significance to pork market management, storage and processing. To quickly detect pork moisture content, a uniplanar capacitance sensor probe with hardware circuit was designed using capacitance detection method in this study. The standard moisture samples were prepared by oven drying method. The calibration experimental results showed that the proposed method can determine pork moisture content quickly for moisture contents were in the range of 60%-76.4% with less than ±1.2% error. The temperature experiments showed that the pork dielectric constant was slightly affected by temperature. The effect of temperature can be neglected within the normal temperature.
