Palm oil contains carotenoid and vitamin E which possess antioxidant properties. A long exposure of heat and chemical substances during the purification process may lower antioxidant activity. This research was conducted to compare antioxidant activity of carotenoid and vitamin E obtained from each stage of three continuous purification process (transesterification, solvolytic micellization, and saponification).
