|
|
To elucidate the contents of phytic acid and minerals in rice produced in Korea, samples of 68 verieties of brown rice and 9 varieties of polished rice were analyzed for phytic acid by colorimetric method, and Ca, Fe, Mg and Zn contents by the atomic absorption spectrophytometer. Selenium was measured by fluorometry. Averages of phytic acid content of the 68 brown rice were 12.6 g/kg, whereas that of the 8 polished rice were 1.83 g/kg on dry matter. Averages of Ca, Fe, Mg and Zn contents on the 68 brown rice were 111, 7.4, 1,068 and 19.1 mg/kg, and those of the polished rice were 45.6, 2.1, 250 and 14 mg/kg, respectively. A averge of selenium content of the brown rice was 38.3 μg/kg.
