This study was investigated (replaced) the sensory and physicochemical properties of Jeungpyun substituted with 30% or 60% of brown rice and barley flours, respectively. The quality changes of the functional Jeougpyun during the storage periods were analyzed by a texturometer. We found that batter pH was decreased as fermentation progressed, but showed a higher pH resulted after steaming. The brown rice replaced Jeungpyun had higher specific gravity and lower viscosity; however, the barley-replaced Jeungpyun had lower specific gravity and higher viscosity compared to those of the control(0% replace with brown rice or barley flour). The barley-replaced samples showed significantly larger volume indexes than that of the control. The L-value of the for lightness decreased significantly within the replaced samples(p<0.001). All samples had negative a-values, with slight peen colors rather than red. The barley-replaced samples were darker than those of the brown rice sample groups, with less green and yellow color. The brown rice-replaced samples had larger values for adhesiveness, overall, and moistness, and the barley-replaced samples showed intensities greater in cell size, springiness, hardness, and flavor by sensory evaluation. The 30% flour-replaced samples of the comparisons had higher values for overall desirability(p<0.001). The replaced samples showed slow increases in hardness when measured by a texturometer, indicating that, the retrogradation rates decreased as the storage periods increased. The control stored for 72 hr had a hardness value that was 8.0 times harder than that of the control stored for one hour. The 30 and 60% brown rice-replaced samples stored for 72 hr were 5.8 times and 4.7 times harder of their replacement level, respectively, and the 30 and 60% barley-replaced samples stored for 72 hr were 5.7 times and 4.2 times harder of their replacement level, respectively. The adhesiveness and cohesiveness of all samples tended to decrease as the storage period increased. The barley-replaced samples showed significantly the lower adhesiveness and cohesiveness during the storage periods. The springiness of all samples decreased slowly during the storage periods. In conclusion, Jeungpyun that was substituted with brown rice and barley flours demonstrated improved functionality and higher dietary fiber replaced effect. Furthermore, the storage period of was extended as the retrogradation rate was delayed as a result of the dietary fibers.
