ABSTRACT
This study aims to obtain the characteristics of active optical properties in corn oil, the most likely asymmetric triglyceride component. The samples used were corn oil 1 and 2 with different brands, and after being heated for 0, 2 hours, 4 hours, and 6 hours. To obtain the characteristics of active optical properties, changes in the polarization angle at various polarizer angles were measured using a laser with 𝜆 = 532 𝑛𝑚. Determination of the most likely asymmetric triglyceride is done by identifying the asymmetric axes (maximum polarization angle), and the combination of triglycerides from GCMS (Gas Chromatography Mass Spectrometry) data. The results of the data on changes in the polarization angle vs. the polarizer angle show that the corn oil sample has active optical properties. The maximum polarization angle changes of 30⁰, and 60⁰ respectively contribute to the most dominant asymmetric triglycerides TBCB and TCBC. The longer the heating, the higher the change in the polarization angle, so it can be said that the relative quality of the oil is decreasing.
