In this study, the attempts were made to Investigate the effect of squalene (200 ppm) on the autooxidation of soybean oil The effect of mixed tocopherols (200 ppm) was also studied In the same way and the results of the study were compared with those of squalene. A put of a commercial soybean oil was stored at 45.0$\pm$0.5t for their autooxidation. The extent of the autooxidation was estimated from the changes of the peroxide value and % conjugated dienoic acid content of the ell substrates The results of the autooxidation, squalene In the soybean oil substrate showed antioxidant activity but the activity was weaker than that of mixed-tocopherols nth the same concentration. The induction periods of the control and substrates with the same concentration. The Induction periods of the control and substrates with squalene and mixed-tocopherols were 448.5 504.9 and 668.9 hours, respectively. Time required to Tech a POV of 30meq/kg oil.
