This study was carried out to investigate the effects of the addition ratio of BARODON^® on the dough volume, moisture content, loaf volume and weight and the sensory characteristics of sprouted brown rice bread. The loaf volume and sensory characteristics of the bread with BARODON^® were higher than those without. The moisture content and loaf weight of the bread with BARODON^® were lower than those without. Although these results were irregular with increasing amounts of BARODON addition. The sprouted brown rice bread with 0.6% BARODON^® gave the best loaf volume and overall acceptance, whereas those with 4.8% BARODON^® had the best odor, color and mouthfeel. BARODON^® will be very useful as a leavening agent for improving the overall quality of sprouted brown rice bread.

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 bread: decreased by 3.2%∼7.4% with the addition of the brown rice flours. The "L" value of these 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 it 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 ${\alpha}$-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.

This study examined the effects of sprouted brown rice (SR), gluten (G), and hydroxypropyl-methyl-cellulose (H) on the suppression of retrogradation in breads made with Korean wheat flour. An amylograph was used to determined the pasting properties of dough samples made with Korean wheat flour and additions of SR, SR+G, SR+H, and SR+G+H, respectively. In addition, a texture analyzer was employed to measure the hardness changes of bread samples left at room temperature for 72 hours. Finally, the type of retrogradation was calculated by the Avrami equation. The results showed that the addition of SR significantly decreased dough viscosity. However, the dough samples containing SR, G, and H all displayed reduced cold paste viscosity and setback, indicating a suppression of staling. The bread samples containing SR added to Korean wheat flour had increased hardness, but the addition of gluten (SR+G) reduced hardness. Upon examining the bread samples stored at room temperature for 24 hours, it was shown that the addition of G and H with SR (SR+G+H) suppressed retrogradation. Finally, the Avrami model data indicated that the type of retrogradation varied according to the addition of SR, G, and H. The breads made with hard wheat flour (HWF), WM, and WM+SR+H had similar Avrami exponents ($1.20{\sim}1.28$), while those for WM+SR, WM+SR+G, and WM+SR+G+H ranged from 2.7 to 3.3. Overall, the combined addition of SR and H was considered effective for preventing retrogradation in bread made with Korean wheat flour.

본 연구에서는 발아현미의 자연식품으로써의 이용효과를 극대화 시켜 이를 이용한 기능성 식빵을 제조하기 위해 발아현미분을 첨가하여 식빵을 제조하고 부피, 무게를 측정하여 제빵 특성을 측정하였으며, 식빵의 성분변화를 살펴보기 위해 일반성분, 환원당, 아미노산, 무기질, 지방산 분석을 행하여 영양성분을 분석하고, 관능검사를 실시하였다. 발아된 현미분 첨가량 증가에 따른 제빵특성을 살펴보면, 대조구에 비하여 현미분 10∼30% 첨가 식빵의 경우 완만하게 부피가 감소하였고, 40% 첨가구는 75.48%, 50% 첨가구는 66.29%로 감소하여 빵의 외형이 허물어지는 결과를 보였으며, 현미분양의 증가에 따른 식빵 무게의 큰 변화는 찾아볼 수 없었고, 발아 현미분의 첨가량은 30%정도까지가 적정한 제빵특성을 나타내는 것을 알 수 있었다. 일반성분, 구성 아미노산 함량의 변화는 발아현미분의 첨가량이 증가함에 따라 회분, 단백질, 지방, 환원당, 섬유소 및 구성 아미노산의 함량이 계속적으로 증가하였으나, 무기질, 지방산 함량은 대조군과 비교하여 큰 차이가 없었다. 발아현미분을 혼합하여 제조한 빵의 관능적인 성질은 발아현미분의 첨가량이 많을수록 대조군에 비하여 색, 외관, texture, 입안에서의 느낌에 대한 기호도는 약간 낮았으나, 씹을수록 느껴지는 고소한 맛과 향이 대조군에 비해 좋은 특성을 나타내어 빵에 대한 전체적인 선호도는 발아현미분 첨가량이 많을수록 더 높았다.

발아현미와 호박분말이 식빵의 품질에 미치는 영향을 조사하기 위해 발아현미 $20\%$와 호박분말 0, 1, 3, $5\%$를 첨가하여 식빵을 제조한 후 부피, 색도, 물성, 관능검사와 영양성분을 조사하였다. 그 결과 호박분말 첨가량이 증가할수록 부피는 4.68 mL/g에서 3.60 mL/g로 감소하였고, L값은 77.46에서 73.36으로 약간 감소하였으며 b값은 10.97에서 27.01로 증가하였다. 호박분말이 첨가된 식빵의 경도, 부착성, 씹힘성은 감소하였으며 점탄성과 응집성은 일정한 경향을 나타내지 않았다. 관능검사 결과 호박분말첨가량이 증가할수록 향, 색, 맛 및 상품성이 증가하였다.
