Cr. Choi et Kt. Hwang, DETECTION OF HYDROCARBONS IN IRRADIATED AND ROASTED SESAME SEEDS, Journal of the American Oil Chemists' Society, 74(4), 1997, pp. 469-472
Hydrocarbons produced by gamma-radiation of sesame seed were analyzed
to determine the relation of irradiation dose to the production of hyd
rocarbons and to eventually use them as markers for identifying post-i
rradiated sesame seed. Hydrocarbons in sesame seed were determined by
a sequential procedure of lipid extraction by hexane, Florisil column
chromatography, and gas chromatography. 16:2, 16:3, 17:1, and 17:2 wer
e prominently detected in irradiated sesame seed. 17:2 was detected in
seed irradiated at 0.1 kGy or higher, and the others were detected at
0.5 kGy or higher. These hydrocarbons were not detected in unirradiat
ed sesame seeds that were raw, roasted, whole, ground, or stored.
