Ritsuko Kishimoto Etsuko Hasegawa Kiyoshi Goda Katsumi Amako Kayoko Nakashima The of food compositions and anthocyanin content in whole-grain rice (100%), well-milled rice (74.9%), the outer layer (17.9%) and the inner layer (7.4%) of purple-black rice, “Murasakinomai”, (M-rice) and in the whole grain of white rice, “Hinohikari”, (H-rice) were measured. In the whole grain of these two kinds of rice, the concentrations of protein, dietary fiber, sodium, potassium, riboflavin and γ-tocopherol (γ-Toc) were higher in M-rice than in H-rice, whereas the concentrations of lipid, iron, zinc and α-Toc were higher in H-rice than in M-rice. The concent of anthocyanidin was 0.24 g per 100g in the whole grain of M-rice, most of this being distributed in the outer layer (1.4 g per 100g in the outer layer). Half-milled M-rice (6.7%) was included in the menu of a school lunch program, and its nutritional content was calculated.
