수입 밀가루와 국산 우리밀가루로 식빵을 제조하고 그 품질특성을 조사하였다. 일반성분의 수분과 조단백질 함량은 수입 밀가루가 가장 낮았고, 조회분 함량은 수입 밀가루 값이 가장 높게 나타내었다. pH 측정에서는 수입 밀가루가 가장 낮게 나타났으며, H.Y 우리밀가루가 가장 높게 나타났다. 색도는 수입 밀가루가 L, a값이 가장 낮게 나타났다. 식빵의 부피와 높이는 G.S 우리밀가루가 가장 낮았으며, 금강 우리 밀가루가 반죽수율과 비체적이 가장 높게 나타났다. 굽기 손실률은 G.R 우리밀가루가 가장 높았으며 G.S 우리밀가루가 가장 낮게 나타났다. 조직감에서는 경도(hardness)는 수입 밀가루가 가장 낮았고, 점착성(gumminess), 씹힙성(chewiness), 부착성(adhesiveness), 탄력성(springiness), 응집성(cohesiveness)은 가장 높게 나타났다. 관능평가에서는 맛과 향미에 대한 기호도의 경우 수입 밀가루보다 우리밀가루가의 모두 높은 점수를 나타내었다.
This study was conducted to investigate the quality of white pan breads baked with various Korean and imported wheat flours. The approximate composition of the Korean wheat flour was 12.0614.06% moisture, 11.8314.02% crude protein, and 0.320.54% crude ash. Relative to the Korean wheat flour, the moisture and crude protein contents of imported wheat flour were lower, and the crude ash content was higher. The pH of white pan bread was lowest with imported wheat flour and highest with H.Y woorimil. The color L and a values in the crumb were lower with imported wheat flour than with Korean wheat flour. The volume and height of dough was lowest with G.S woorimil, and the specific volume and yield of dough was highest with K.K woorimil. The baking loss rate of bread was highest with G.R woorimil and lowest with G.S woorimil. In texture characteristics, hardness was lower and chewiness, adhesiveness, springiness and cohesiveness were higher with imported wheat flour than with Korean wheat flour. In the sensory evaluation, breads made with Korean wheat flour were superior in taste and flavor to bread made with imported wheat flour.
