Abstract

This study investigated the quality characteristics of breads made with addition of lotus(Nelumbo nucifera) seeds powder. Breads were prepared with 0, 5, 10, 15 and 20%(w/w) lotus seed powder instead of wheat flour. The moisture, crude protein, crude fat, crude ash and crude fiber contents of the breads increased as the proportion of lotus seed powder increased. The pH of the breads increased as lotus seed powder levels increased. The weight of breads increased with increasing lotus seed powder levels, whereas volume decreased. The specific volumes of breads with lotus seed powder were in the range of $3.59{\sim}4.68\;mL/g$, whereas the control value was 5.12 mL/g. The baking loss rates of breads prepared with 5%, 15% and 20% lotus seed powder were 8.95%, 8.17% and 7.67%, respectively. Lightness (L value) of breads was decreased by addition of lotus seed powder, whereas redness (a value) and yellowness (b value) increased in crumb and crust. Texture measurements showed that hardness and gumminess increased with increased lotus seed powder levels, but springiness decreased. In sensory evaluation, the highest scores for flavor, taste and overall preference were obtained when lotus seed powder content was 10%, and color and texture were the best when 5% of lotus seed powder was added. Thus, addition of $5{\sim}10%$ lotus seed powder may have a role in functional bread preparation, resulting in improved quality.

연자육 분말을 밀가루 중량에 대해 0, 5, 10, 15, 20%를 첨가하여 제조한 빵의 품질 특성을 조사하였다. 빵의 일반성분을 조사한 결과 연자육 분말 첨가량이 증가할수록 수분, 조단백질, 조지방, 조회분과 조섬유 함량 등이 증가하였다. pH는 대조구 보다 연자육 분말 첨가구가 높게 나타났다. 빵 무게는 연자육 분말 첨가량이 증가할 수 록 증가하였으며, 부피는 감소하였다. 빵의 비용적은 연자육 분말 첨가구가 $3.59{\sim}4.68\;mL/g$이었고, 대조구는 5.12 mL/g이었다. 연자육 분말 5%, 15%, 20% 첨가구에서 굽기 손실율은 각각 8.95%, 8.17%, 7.67%로 나타났다. 연자육 분말을 첨가한 빵의 crumb와 crust 색도를 측정한 결과, 연자육 분말 첨가량을 증가할 수 록 명도 L 값은 감소하였으나 적색도인 a 값과 황색도인 b 값은 증가하였다. 연자육 분말 첨가량을 증가할 수 록 빵의 경도와 점착성은 증가하였으나 탄력성은 감소하였다. 연자육 분말 첨가 빵의 관능검사 결과, 향미, 조직감, 전체적인 기호도는 연자육 분말 10% 첨가구가 가장 높은 점수를 보였으며, 색도와 조직감은 5% 첨가구가 가장 높은 점수를 나타내었다. 본 연구를 결과를 종합해 볼 때 연자육 분말 $5{\sim}10%$를 첨가할 경우 기능성 빵으로 개발 가능성이 높다고 판단된다.
