Abstract

This study was carried out to investigate the quality of white pan bread as affected by various amounts of Sunsik powder, in which the breads were prepared with 0, 5, 10 and 15% Sunsik powder. The samples compared quality characteristics, including proximate composition, weight and height, fermentation time, baking loss rate, texture, sensory evaluation in order to determine the optimal amount of Sunsik powder in the formulation. The moisture content of control bread was higher, in the breads made with Sunsik powder. The baking loss rate decreased with increasing Sunsik powder concentration. The fermentation time of the bread increased with increasing Sunsik powder content. In sensory quality, the bread containing 5% Sunsik powder was preferred over the control bread, by color, taste, flavor and softness, while the 15% Sunsik powder bread had the lowest preference scores. Textural properties by TPA(texture profile analysis) showed that hardness, gumminess, chewiness increased with increased Sunsik powder concentration.

선식의 농도를 달리하여 제조한 식빵의 일반 성분 분석결과, 수분 함량은 대조구가 가장 높게 나타났고, 선식을 첨가한 식빵은 대조구에 비해 낮게 나타났다. 조회분의 경우, 대조구가 1.34%로 가장 낮게 나타났고, 선식의 첨가량이 증가할수록 증가하였다. 조단백칠 함량은 대조구가 가장 높게 나타났고, 선식을 첨가한 식빵이 낮게 나타났으나 유의적인 차이는 없었다. 조지방의 경우, 선식의 첨가량에 따라 증가하였다. 식빵의 무게는 대조군이 가장 낮았다. 높이는 선식의 첨가량이 증가할수록 낮아졌다. 반죽의 발효 시간은 대조구가 가장 짧았고 선식을 첨가한 식빵의 발효 시간이 길게 나타났다. 굽기 손실률은 대조구가 가장 높게 나타났고, 선식의 첨가량이 증가할수록 감소하였다. 견고성은 선식을 15% 첨가한 식빵이 가장 높았고, 대조구가 가장 낮게 나타났다. 응집성은 선식 5% 첨가 식빵이 가장 높게 나타났고, 선식 15% 첨가 식빵이 가장 낮게 나타났다. 검성과 씹힘성은 선식 15% 첨가 식빵이 가장 높게 나타났고, 대조구가 가장 낮게 나타났다. 부착성은 선식 5% 첨가 식빵이 가장 높게 나타났으나, 선식 15% 첨가 식빵과 유의적인 차이는 없었다. 탄력성 측정 결과, 모든 시료간의 유의적인 차이는 나타나지 않았다. 관능 검사 결과, 색은 대조구와 선식 5%, 10% 첨가 식빵이 높게 나타났고, 선식 15% 첨가 식빵의 기호도가 가장 낮게 나타났다. 향미는 선식 5% 첨가 식빵이 가장 높게 나타냈고, 선식 15% 첨가 식빵이 가장 낮게 나타났다. 부드러움은 선식 5%와 10% 첨가 식빵이 가장 높게 나타났고, 전체적인 기호도의 결과는 선식 10% 첨가구가 가장 높게 나타났다. 맛과 조직감은 모든 시료에서 유의적인 차이가 없었다. 이상의 결과에서 선삭 5%와 10% 첨가구가 품질 특성이 높은 것으로 나타났다.
