The concentration of nutrients in brown rice is mainly associated with embryo size. Various beneficial components have been purified from rice bran. Recently developed black waxy rice with a giant embryo ('Milyang 263', BGE), which is the ge (t) mutant of the GE gene, was selected and analyzed to produce high quality nutritional components. gamma-Aminobutyric acid (GABA) content in BGE rice bran, one of the most important nutritional compounds in rice, showed a 10.6-fold increase (2.66 +/- 0.48 mg/g) compared to that of BGE brown rice (0.25 +/- 0.01 mg/g). In addition, brown rice and BGE rice bran showed enriched amylopectin (94.5 +/- 0.5 and 97.0 +/- 0.0%) and bioactive anthocyanin [Cy-3-G: 75.15 +/- 4.18 (brown rice), 82.97 +/- 0.81 (rice bran) and Pn-3-G: 1.52 +/- 0.50 (brown rice), 4.33 +/- 0.20 (rice bran); mg/100 g] contents. These results suggest that BGE rice bran can be used as an excellent raw material to efficiently produce high quality essential amino acids, cyanidin-3 glycoside-enriched anthocyanins, and GABA.
