In this study, silicone oil was added into soybean oil in order to investigate its effect on acid value (AV), carbonyl value (COV), TBA value, fatty acid composition and color intensity of soybean oil during frying at $170^{\circ}C$. It was found that the AV, COV and TBA value were significantly decreased as the concentration of silicone oil increased from 0 to 5 ppm in soybean oil after frying for 7 hours. The color intensity was also decreased by 26% of color of 7 hours-heated soybean oil without silicone oil addition. Little changes in fatty arid composition was measured between the samples after 7 hours frying. From the overall result of this study, addition of silicone oil by 1 ppm was recommended for effective reduction of rancidity development of soybean oil ing frying.
