다국어 초록 (Multilingual Abstract)

This study was carried out to investigate the quality of bread made with different types of brown rice flours. 20% of the wheat flour from the bread recipe was substituted with the different types of brown rice flours, such as, raw brown rice flour (RBRF). soaked brown rice flour (SOBRF), and sprouted brown rice flour (SPBRF). The loaf volume of the breads decreased by 3.2%~7.4% with the addition of the brown rice flours. The L value the hardest breads decreased, while the a and b values increased. In terms of the texture, the SPBRF bread was the hardest on the 1st day of storage, but is was the least hard on the 5th day of storage. The RBRF bread was the least springy. The SPBRF bread was the most cohesive. The adhesiveness was not significantly different among the breads. In terms of the degree of retrogradation using the -amylase method, the SOBRF and SPBRF breads showed a little lesser degree of retrogradation than the control and the RBRF bread. In the sensory evaluation, the control bread obtained high score for crumb color and grain, while the brown rice flours breads obtained high scores for mouthfeel and taste. Overall acceptability, defined by a higher score, was higher for the SOBRF and SPBRF breads than the control bread, which was not significant. Thus, this study showed that processing rice flour was more effective than raw rice flour in substituting wheat flour.
