INAA for the evaluation of selenium contents in grain foods consumed by Korean
- 129 Downloads
This study was aimed to measure the Se content in common consumed grain and potato foods. About 1 g of analytical sample of 40 items of foods was irradiated for 3 h by thermal neutrons (Φ th = 2.8 × 1013 n/cm2 s) and 75Se nuclide was used for the determination of Se contents. The rice showed the range of Se contents from 0.55 to 3.64 μg per 100 g of sample. The Se contents in grain products varied according to the type of grain processing. The acquired Se value in this study will be useful to assess the Se intake of Korean.
