Efficacy of common lipid antioxidants was evaluated by use of sesamol dimer and hemoglobin (SD method), and the method was compared with traditional peroxide value (POV) method. There were good correlations between the increases in SD and POV values, with different substrate oils and with the different antioxidants. While the POV method requires 500 mg of the substrate oil, the SD method requires less than 10 mg of the oil. The SD method is useful to estimate the potency of antioxidants with a small amount of oils and fatty esters.
