Abstract
The composition of fatty acids, minerals, total dietary fiber and vitamin $B_1,\;B_2$, in pigmented rice varieties were determined. Proximate composition and color were also compared among pigmented rice varieties. Crude protein contents of black rice were higher than those of red and white rice, especially, C3GHi line had the highest protein content. There were no significant differences in lipid and crude ash contents between pigmented and white rice. Black rice showed lower Hunter value L and b value compared with red, green and white rice. But, Green rice showed lower Hunter value a compared with black rice. Green rice showed the higher contents in total dietary fiber, vitamin $B_1\;and\;B_2$ compared with white and black rice. The major fatty acids of pigmented rice were palmitic acid, oleic acid and linoleic acid. The contents of oleic acid was similar to that of linoleic acid in white rice. Oleic acid contents was lower than linoleic acid in black rice, but higher in red rice. Most mineral contents of pigmented rice except Fe, Zn and Mn were higher than those of white rice. Especially, Green rice had the highest mineral content.
