| Colored rice or pigmented rice refers to the color of rice kernel such as black, purple and red which is form by deposits of anthocyanin in different layers of the pericarp, seedcoat and aluerone layers. This experiment was to evaluate nutritional values (anthocyanin, iron and zinc) of rice grain among local colored rice varieties. Variation among varieties for anthocyanin, iron and zinc concentrations were found in brown rice, white rice and bran. Significant amount of anthocyanin concentration was found in black color rice, whereas very low concentration was found in red and brown color rice. Among all black rice, the highest anthocyanin concentration was found in Niaw Dam 6 collected from Udon Thani (90 mg/100 g in brown rice) and (820 mg/100 g in... |
