Abstract

To compare chemical properties of irradiated legumes (soybean, peanut, red bean, mung bean) produced in Korea and China, radiation-induced hydrocarbons from the samples were investigated. The legumes were gamma-irradiated at 0.5, 1, 2 and 4 kGy, from which lipid was extracted with hexane. Hydrocarbons were separated by florisil column chromatography and then analyzed with GC-MS method. The chromatograms of irradiated samples showed several radiation-induced hydrocarbons, which were affected by the fatty acid compositions of legumes. Hydrocarbons, such as 1, 7, 10-hexadecatriene (16:3),6,9-heptadecadiene (17 : 2), 1, 7-hexadecadiene (16 : 2) and 8-heptadecene (17 : 1), were predominantly detected in soybean, peanut and red bean irradiated at 0.5 kGy or above, whereas 17 : 1 was not found in mung bean. The detected amount of hydrocarbons increased with irradiation doses. There is no apparent difference in qualitative and quantitative profiles of the corresponding hydrocarbons depending on the origin of legumes.

방사선 조사 식품의 검지방법을 연구하기 위하여 국산 및 중국산 두류(대두, 땅콩, 적두, 녹두)를 대상으로 0.5~4kGy의 감마선을 조사하여 hydrocarbon류의 생성특성을 비교하였다. Hexane을 이용하여 추출한 지방질을 florisil column chromatography에 의해 hydrocarbon류를 분리시키고 GC-MS에 의해 분석하였다. 방사선 조사된 각종 두류의 hydro-carbon 생성특성은 다소 상이하였고, 두류의 지방산 조성에 영향을 받았다. 대두, 땅콩 및 적두에서는 0.5 kGy 혹은 그 이상으로 조사시켰을 때 16 : 3, 17 : 2, 16 : 2 및 17 : 1을 각각 확인할 수 있었으나, 녹두에서는 17 : 1이 검출되지 않았다. 국산 및 중국산 두류에서 방사선 조사 유래의 hydrocarbon류 생성량은 조사선량에 비례하였다. 그러나, 방사선 조사 유래 hydrocarbon류 생성량은 조사선량에 비례하였다. 그러나, 방사선 조사 유래 hydrocarbon류의 종류와 양에는 원산지별 차이가 나타나지 않았다.
