- This research discusses the electrical impedance measurements using the four-probe method on the lard and beef fat. This research is a continuation of previous studies that do fat impedance measurements at high frequencies by using the two-probe method. Analysis of four probe models can indicate changes in the electrical properties of the material when the material contains different liquid media based on its impedance and minimizes the effect of the double layer. The saturated and unsaturated fatty acids contained in each fat will determine the electrical properties of the material In this study, will explain four-probe electrical impedance measurements of lard fat mixture in beef fat by giving 100 μA current at a frequency of 1 Hz to 1MHz. The results showed that the electrical impedance of both fats decreased with increasing frequency. The electrical impedance of the fat cows smaller than lard. The impedance meter works well at frequencies up to 1 Hz-1MHz. The addition of the mixture concentration of lard will cause an increase in the value of the electric impedance of beef fat.
