Abstract

Total Polar Compound (TPC) is a chemical parameter which reflects the deterioration of the high temperature of cooking oil. The repeated use of cooking oil at high temperatures result in undesirable substances are generated, which may cause health problems. This project is to design a sensor based on capacitive (dielectric sensing) using interdigitated electrode structure in order to detect the TPC level of cooking oil obtained from the experiment using a probe to measure the electrical properties and related it to the TPC level of the oil samples. A total of 15 samples of 150 ml palm oil was heated at 150 up to 15 hours. For each one hour interval, one sample was moved out from the laboratory oven. The expected result determined the levels of TPC in cooking oils that are obtained from the experiments and relate it capacitance of the samples. The dielectric properties of oil samples were investigated in the frequency range of 0.1-10 kHz. The best frequency chosen gave the capacitance was increasing linearly with heated time. The results analysis of significant correlation between the electrical capacitance of the oil sample with TPCagainst heated time with R2 ranged from 0.805 to 0.852.
