Residual sterylglycosides (SG) and octacosanedioic acid (DA 28) in commercial sesame oil were investigated for 17 brands of 12 manufacturers. A sensitive and precise method was developed to determine DA 28 content in oil. DA 28 was derived from 9-anthryldiazomethane in the presence of triacylglycerol and determined by HPLC equipped with a fluorescence detecter. This method was rapid and applicable to routine analysis.
SG and DA 28 content differed considerably according to brand, from 1 to 300 ppm and 0 to 1500 ppm, respectively. The steps in oil processing would thus appear to markedly affect SG and DA 28 residue content
