The optimal replaced percentage of brown rice Jeung-pyun was investigated in this study. A specific volume of brown rice Jeung-pyun resulted in no difference. The pH of Jeung-pyun (5.10-5.39) was higher than that of Jeung-pyun dough (4.96-5.17). The lightness darkened to 55.39-63.56, as the replaced amount of brown rice flour was increased. Furthermore, redness and yellowness increased to 3.24-4.15 and 4.45-10.12, respectively. The microstructure examined by scanning electron microscopy became enlarged and irregular as the amount of replaced rice increased. The gelatinization of 30-40% brown rice powder was approximately 1.93-2.20. The mechanical textures of hardness, gumminess, chewiness, and fracturability were high as additional ingredients and the storage period increased, whereas adhesiveness, springiness, and cohesiveness were low. The results of a sensory evaluation revealed that the 30% added brown rice Jeung-pyun was highly assessed as the most appropriate percentage of added brown rice Jeung-pyun.
