제빵용 시판 강력분에 연잎 분말을 첨가한 건강 기능성 식빵 제조를 위하여 연잎 분말의 첨가량을 2.5%-7.5%로 변화시키면서 반죽에 대한 물성, 식빵의 저장성, 제빵적성 및 관능적 특성을 조사하였다. 식빵의 비용적은 연잎 분말 2.5% 첨가구에서 약 5%의 증가를 보였으나 연잎 분말 5%, 7.5% 첨가구의 경우는 각각 대조구의 87%, 80%에 상당하는 비용적을 나타내어 연잎 분말의 첨가량이 증가할수록 식빵의 비용적은 감소하는 경향을 나타내었

Bread made after replacement of commercial hard wheat flour with lotus leaf flour (2.5 - 7.5%, w/w) was tested for dough and baking qualities, and by sensory evaluation. The loaf volumes of bread baked with 5% and 7.5% lotus leaf flour were 87% and 80%, respectively, of control (wheat flour only); by contrast, the volume of bread baked with 2.5% lotus leaf flour was 5% greater than control. The hardness of breadcrumbs baked with 2.5% lotus leaf flour was 64.5 g on day 0, and compared with control bread, hardness increased more slowly during storage for 3 days when 5% or 7.5% lotus leaf flour was used. Moreover, dough hardness increased with increasing levels of lotus leaf flour. Lightness decreased with addition of lotus leaf flour, but redness and yellowness significantly increased, in proportion to lotus leaf flour levels. Sensory tests on 2.5% lotus leaf flour bread showed no significant difference compared with control.
