쌀식빵의 부피는 대조구(밀가루 빵)와 RF 3 조건(쌀가루와 밀가루 혼합조건) 및 RF 1(쌀가루, 글루텐 및 변성전분 혼합조건)에서 높게 나타났다. 쌀식빵의 crust와 crumb의 색도를 색 차계를 이용하여 측정한 결과, 쌀식빵 crust의 명도 L값은 RF 5과 RF 6 조건에서 가장 높았지만, 쌀식빵 crumb의 명도 L값은 RF 1이 가장 낮았다. 쌀식빵의 경도(hardness), 탄력성 (springiness), 씹힘성(chewiness) 및 응집성(cohesiveness)등은 texture analyzer를 이용하여 측정하였다. 쌀식빵의 경도는 RF 1과 RF 2 조건이 대조구에 비해 낮았으며, 탄력성, 씹힘성은 대조구에 비해 쌀가루가 첨가된 RF 1, RF 2 와 RF 3조건에서 높은 수치를 나타냈고, 응집성은 대조구와 RF 3조건에서 낮게 나타났다. 전체적인 기호도는 쌀 고유의 향과 부드러운 조직감을 갖는 RF 1 조건 즉 쌀가루 85%, 글루텐 5% 그리고 변성전분 10% 첨가된 식빵의 선호도가 높았다.
The characteristic properties of rice breads produced from several conditions were investigated. The rice bread made in control condition (wheat flour), RF 3 (rice and wheat flour mixing) condition and RF 1 (rice, gluten and modified starch mixing) showed relatively higher volumethan others. The crust and crumb color were measured by Humter colory meter. The rice breads making on RF 5 and RF 6 condition showed higher crust L-value and the crumb L-value of the bread from RF 1 condition was higher than that from other condition. On the texture measuring by texture analyzer, hardness of the bread made from RF 1 and RF 2 conditions and cohesiveness of that from RF 3 condition were lower than control. However the significant higher level of the springiness and chewiness were showed in the bread from RF 1, RF 2 and RF 3 condition. The bread containing 85% of rice, 5% of rice, 5% of gluten and 10% of modified starch which was made in RF 1 condition obtained significant high overall acceptance score by sensory evaluation.
