Abstract

This study was carried out to investigate nutritional composition and physicochemical properties of waxy(WGR) and nonwaxy(NWGR) germinated brown rice. Amylose contents of WGR(moisture content 15.45 %) and NWGR (moisture content 15.02%) were 4.9% and 17.9%. Reducing sugar of those were 4.91% and 2.28%. The free sugar contents of WGR were glucose 0.42%, sucrose 0.15%, maltose 0.27% and that of NWGR were glucose 0.59%, sucrose 0.50%, maltose 0.24%, respectively. Color value of WGR and NWGR were L=60.30, a=2.12, b=23.52 and L=59.51, a=3.15, b=23.04, respectively. Degree of gelatinization of WGR and NWGR were 7.67%, 5.21% and hardness of WGR and NWGR were 7.53 kg$\_$f//$\textrm{cm}^2$, 8.93 kg$\_$f//$\textrm{cm}^2$. Vitamin E contents of those were 271.8 $\mu\textrm{g}$/kg, 310.6 $\mu\textrm{g}$/kg and total dietary fiber contents of those were 4.21%, 3.17%. Total amino acids of brown rice, nonwaxy germinated brown rice and cooked germinated brown rice were 126.8 mg/l00 g, 90.8 mg/l00 g and 106.5 mg/l00 g, respectively. Among amylogram characteristics of WGR and NWGR, initial gelatinization temperature, peak viscosity, breakdown, setback were 42$^{\circ}C$, 498 B.U., 94 B.U., -48 B.D. and 70$^{\circ}C$, 212 B.D., 0 B.D., 123 B.D., respectively. Sensory properties of germinated brown rices were affected by color and flavor. Palatability score of WGR that intensity score of color and flavor were lower than that of NWGR showed high.
