| Outline of Final Research Achievements |
Bread-making quality of the brown rice powder produced by the roll milling method was inferior to that of the white rice flour produced by the enzyme processing-milling method. This was because the average grain diameter, the starchy damage level and the water absorption coefficient of the brown rice powder were higher than those of the white rice flour. The amounts of γ-aminobutylic acid (GABA) which is one of the functional ingredients of brown rice were increased at 3.4 times after the first fermentation process. But that decreased at 2.2 times after the secondary fermentation and the baking process. It is suggested that the decrease of GABA was caused by the yeast work and the browning reaction (amino-carbonyl reaction) by baking bread. It will possible to produce the GABA rich brown rice bread by improving the bread-making conditions such as the dough's pH, the fermentation temperature and the baking time.
