Abstract

This study was conducted to investigate change in the quality of white pan bread as affected by various concentrations of Corni fructus powder. Breads were prepared by addition of 0, 1, 2 and 3% of Corni fructus to wheat flour of basic formulation. The moisture content of white pan bread was approximately $37.5{\sim}41.1%$ and decreased with increasing Corni fructus powder concentration. The pH of white pan bread also decreased with increasing Corni fructus powder concentration. In color values, with increase of Corni fructus powder concentration, L, a value decreased and a value increased in the crumb. The weights of bread cooled for 0, 1 hour and 3 hour after baking decreased with increasing Corni fructus powder concentration. The volume and height of dough increased with increasing Corni fructus powder concentration. However, no significant differences in the specific volume and yield of dough were found. The baking loss rate was higher in the breads with Corni fructus powder than in the control. In the texture characteristics, hardness, gumminess and chewiness of bread significantly decreased with increasing Corni fructus powder concentration and adhesiveness, cohesiveness increased. In the sensory evaluation, when compared to the control, the bread added to 1% of Corni fructus powder was superior texture and taste and flavor, while was similar to color.

전라남도 구례지방 특산물인 산수유의 소비 촉진을 위하여 산수유 분말의 농도에 따른 식빵의 가공 및 관능적 특성에 미치는 영향에 대하여 살펴보았다. 식빵의 수분 함량 및 pH는 각각 $37.5{\sim}41.1%$$4.7{\sim}5.2$ 범위로 산수유 분말 첨가량이 증가할수록 감소하였다. 식빵의 색도는 산수유 분말의 첨가량이 증가할수록 명도는 감소하였으나, 적색도와 황색도는 증가하였다. 식빵의 무게는 대조구가 가장 높았고, 부피, 높이, 비용적과 굽기 손실율은 대조구가 가장 낮았으며, 산수유 분말을 3% 첨가한 식빵이 가장 높게 나타났다. 대조구에 비하여 산수유 분말 첨가 식빵은 경도(hardness), 점착성(gumminess) 및 씹힘성(chewness)의 경우 감소하였고, 부착성(adhesiveness)과 점착성(cohesiveness)은 증가하였다. 관능검사 결과는 대조구에 비하여 산수유 분말 1%첨가 식빵이 맛과 향미, 조직 감에서 가장 우수하였고(p<0.05), 색은 3% 첨가구가 높은 점수를 받았다. 이상의 결과 물리화학적 특성 및 관능적 특성으로 미루어 보아 산수유 분말 첨가 식빵의 제조를 위한 최적 산수유 분말 첨가량은 1%로 판단된다.
