Pregerminated brown rice (PGBR) prepared by immersing in water was used for breadmaking, and effects on the dough properties and bread qualities were studied to compare with the ungerminated brown rice (BR). The substitution of BR or PGBR for wheat flour produced smaller specific volume in bread than in the control bread without BR or PGBR along with the increasing amount of substitution. However, the bread samples containing BR or PGBR suppressed staling during storage. The improving effect was especially obvious for substitutions of 10 and 20% PGBR as compared with BR. PGBR made viscous dough and retarded the staleness of bread compared with BR. gamma-Aminobutyric acid and oryzanol did not contain in the final BR and PGBR substituted bread, and phytic acid was decomposed approximately equal to 54 and 45% for 30% BR and 30% PGBR substituted breads, respectively. But ferulic acid was quite stable in the final baked product. As a result, substitution of PGBR for wheat flour improved the bread quality.
