The contents of minerals of the milled fractions of degermed Japonica and J/Indica brown rites were determined. The fraction I(about 4.4% of the kernel weight) contained 14. 8 times as much sodium as did the original kernel; phosphorus, 5.7 times; potassium and iron, 5.4 times; magnesium, 4.2 times; calcium, 3.8 times; manganese, 3.7 times; Copper, 3.6 times; and Zinc, 2.3 times. Concentrations of these minerals were the lowest in the residual kernel, which contained less than the original brown rice. Sodium showed the most deepest concentration gradient, while iron w-as the most evenly distributed within the kernel in all samples.
