A method using a tiny thermistor as heat transfer model was developed to measure thermal conductivity of food,and analysis of influence of the calibration,the medium size and heating power.The results showed that water and glycerin as calibration of the thermistor had higher accuracy,maximum measurement relative error of thermal conductivity for some standard samples was 5.02%.Thermistor based method applied to the conductivity measurement of food medium.The relative deviation of thermal conductivity for samples was less than 4% by thermistor based method and heat probe method.
