A study and analysis of cooking oil quality determiner based on planar electromagnetic sensor array

Abstract

Oil palm cooking oil is one of the main foods ingredients in Malaysian food. Almost all recipes are using oil palm cooking oil to cook the food. That’s make the oil palm cooking oil become the main material for making a food. In this project, determining the quality of oil palm cooking oil will be the main issue. Therefore, this project ambitious to invent a low cost system for detecting the tainted cooking oil. As a result, the planar electromagnetic sensor array is proposed. Furthermore, electrochemical impedance spectroscopic (EIS) approach can describe the variation and characteristic of the oil palm cooking oil sample. EIS is about impedance level affected by the sample that being testing. This project suggests an alternative method for the detection of tainted cooking oil by developing a sensor array with the combination of planar meander and interdigital electromagnetic sensors for cooking oil quality inspection. The main objective is to fabricate the sensor array using printed circuit board (PCB). To project will study and analyze the value of the planar sensor impedance (real and imaginary part) as a function of frequency when subjected to cooking oil samples. The relationship between permittivity and conductivity will be determined after the reference measurement is obtained first. That means every result from sample is compare to the good cooking oil sample as reference. A set of experiments were conducted to determine the relationship between the sensor’s output and the cooking oil parameter. To complete this project, two major parts should be carried out which are the hardware setup and result analysis. The hardware part is to get the result from the testing sample by developed a complete set of sensor and equivalent circuit. In the result analysis, the value of impedance from LCR meter will be used to estimate the type of cooking oil.
