초록
The purpose of this research is to detect whether agricultural products were electronbeam irradiated or non-irradiated by chemical methods according to increase of storage period. The three fat-rich samples including soybean, walnut, and sesame were chosen as agricultural products,and then were irradiated with doses of 1~10 kGy by using 10 MeV electron beam facility. At the result, 8-heptadecene and 1,7-hexadecadiene, which are indicators of electron beam-irradiationin chemical methods by gas chromatography/mass spectrometry (GC/MS) method, were detectedin all three samples. The levels of two irradiation indicators were increased by electron beamirradiationin a dose-dependent manner. Furthermore, two irradiation indicators also were detectedin all samples in 6 and 12 months after irradiation, though levels of those were decreased in a timedependentmanner. These results mean that the quantification of 8-heptadecene and 1,7-hexadecadienecould determine whether electron beam were irradiated or non-irradiated until 12 monthafter irradiation in 3 fat-rich agricultural products including soybean, walnut, and sesame.
