쌀을 주재료로 한 쌀 식빵의 제빵 적성을 향상시키고자 제빵 과정 중에 ascorbic acid와cysteine을 첨가하여 식빵의 품질특성을 조사하였다. 쌀 식빵의 RB-3의 경우, 부피는 2,467 mL/kg, 쌀 식빵의 비용적은 5.21 mL/g 그리고 제빵수율 148%로 나타나 상대적으로 다른 배합비로 제조한 식빵에 비해 큰 체적 및 제빵 수율을 나타냈다. 쌀 식빵 crust의 명도 L값은 쌀가루 함량이 높아질수록 높은 값을 나타내었고, cr

The favorable effect of ascorbic acid and cysteine on the improvement of rice bread quality was investigated by creating and comparing 6 experimental rice breads(RB-1 to RB-6). The RB-3 showed a relatively higher loaf volume, specific loaf volume and bread yield than the other breads. Crust and crumb color of breads were measured using a Hunter celery meter. The RB 5 and RB 6 showed the higher cut L-value than the other broads. As the proportion of the rice in the experimental breads increased, both the crust L-value and the crumb L-value showed higher values. According to the texture profile analysis, the hardness of the RB-1 to RB-3 were lower than those of the other breads. The springness of the experimental broads increased as the percentage of the rice in the breads increases. However, less proportions of rice to breads provided significantly lower level of the chewiness. The cohesiveness did not show any specific pattern by the proportion of rice to breads. The degree of retrogradation of the breads was accelerated when the breads contained more rice or when the breads had neither ascorbic acid nor cysteine. Therefore, RB 3, which contained ascorbic acid and cysteine and less rice, showed the highest retardation in the degree of retrogradation. In addition, the RB 3 showed the highest overall acceptance scores by sensory evaluation.
