비지가루의 제빵 적성을 알아보기 위해 밀가루에 5%, 10%, 15% 혼합한 빵을 만들고 비지빵의 제빵성을 향상시키기 위해 10% 비지가루 혼합분에 글루텐을 3%, 6%, 9% 첨가한 빵을 만들어 제빵 적성을 조사하고 관능검사를 실시하였다. 비지가루는 단백질 22.0%, 지방 13.2%, 탄수화물 54.3%, 그리고 식이섬유 27.2%를 함유하고 있었다. 영양성분이 풍부한 비지가루를 밀가루에 혼합하여 식빵을 만들었을 때 비지가루의 혼합비율이 증가함에 따라 수분흡수율, 반죽시간, 빵의 무게는 증가하였고 dough의 팽창력과 빵의 부피는 감소하였으며 10% 비지가루 혼합분에 글루텐을 첨가함으로서 제빵 적성이 향상되었다. 빵의 crumb의 색도는 비지가루의 함량이 증가할수록 어두워졌으나 활성 글루텐의 첨가로 밝아졌다. 빵의 texture도 비지가루의 혼합비율이 높을수록 씹힘성, 경도는 증가하였으나 응집성은 차이가 없었고, 황설 글루텐의 첨가로 탄력성, 씹힙성, 경도는 증가하는 경향을 보였다. 관능검사 결과 5% 비지가루를 혼합하여 만든 빵은 종합적인 기호도에서 밀가루빵과 차이가 없었으며 10% 비지가루 혼합분에 6% 글루텐을 첨가하여 만든 빵은 글루텐을 첨가하지 않은 10% 비지가루 혼합분 빵보다 종합적인 기호도에서 좋은 평가를 받았다. ◁표삽입▷ 원문을 참조하세요

When the soybean milk residue flour were added to the respective wheat flour at level of 5%, 10% and 15% the possibility of bread making were studied. Vital gluten was added to the soybean milk residue portion of a 10% composite flour at levels of 3%, 6% and 9% to improve bread quality. And test was baking properties of soybean milk residue composite flour and sensory evaluation of composite breads. Major components of soybean milk residue flour were crude protein, 22.0%; crude lipid, 13.2%; carbohydrate, 54.3%; and dietary fiber, 27.2%. When 5%, 10% and 15% soybean milk residue flour was blended with wheat flour, water absorption, development time and bread weight were increased, and volume of dough and loaf was decreased. But improved bread-making properties by adding gluten. Color of crumb got darker as the percentage of soybean milk residue flour increased, got brighter when gluten was added. Texture of bread increased in chewiness and hardness as the percentage soybean milk residue flour increased but not different in cohesiveness. The use of vital gluten showed influence to springiness, chewiness and hardness. The sensory evaluation showed that 5% soybean milk residue-wheat bread was similar to bread made from wheat flour in overall acceptability. And the bread made by mixing gluten were better than 10% soybean milk residue-wheat bread in overall acceptability.
