시판 국내산 및 수입산 밀가루 특성과 가공적성 평가

Abstract

Flour characteristics and end-use quality of 10 commercial flours produced from Korean wheat (Kcom) were evaluated to assess consumersatisfaction with Korean wheat compared with commercial flour (Com) prepared from imported wheats. Two types of Kcom, whole wheatflour and white wheat flour, were found in various markets. Whole wheat flours showed higher ash and protein content, lower lightness, and higher water absorption in mixography, than did white wheat flours. The amylose content of Kcom was similar to that of Com, but peak viscosity and breakdown of Kcom were lower than those of Com. Noodle dough sheet prepared from white flours of Kcom was thinner and lighter than dough sheets prepared using whole wheat flours. Compared to Com, Kcom showed lower noodle dough sheet lightness. The hardness of cooked noodles prepared with Kcom was similar to that of noodles made from Com. When used for bread baking, Kcom showed lower loaf volume, lower crumb lightness, and higher crumb firmness, than did Com.

국내산 시판 밀가루의 품질 평가를 통하여 국내산 밀의 품질 향상 방향과 향후 개선 방향의 기초 자료로 이용하고자 수입산 밀가루와 비교 평가하였다. 시판되는 국내산 밀가루는 통밀 밀가루 백밀 밀가루의 두 가지 형태로 판매되고 있으며, 통밀 밀가루는 백밀 밀가루에 비해 회분함량과 단백질함량이 높고, 밀가루 색이 어두었으며, 반죽시 높은 가수량을 보였다. 국내산 밀가루의 단백질 함량은 수입산 강력분 정도로 높았지만 침전가와 반죽시간은 중력분과 비슷하였다. 국내산밀로 만든 시판용 밀가루의 아밀로스 함량은 수입산과 큰 차이는 었지만 전분의 호화 최고 점도와 breakdown이 떨어지는 것으로 나타났다. 국내산 밀가루의 가공적성 평가 결과 백밀 밀가루의 국수 면대는 통밀 밀가루로 만든 면대보다 두께가 얇고, 면대색이 밝았지만 수입산 시판 밀가루보다는 면대색이 어두웠다. 삶은 국수의 경도를 측정한 결과 국내산 시판 밀가루는 수입산 중력분 밀가루와 비슷하였고 제방 적성은 강력분에 비해 빵 용적이 적고, crumb도 어둡고, crumb의 경도도 높아서 떨어지는 것으로 나타났다.
