초록
묵의 원료로 사용되는 동부, 녹두, 도토리와 묵의 원료로 사용되지 않는 팥, 밀, 고구마로부터 전분을 분리하여 이화학적 특성과 분자구조적 특성을 비교하였다. 아밀로오스 함량은 두류인 동부, 녹두, 팥에서 높았고, 밀, 도토리, 고구마의 순으로 낮았다. 아밀로그램에 의한 호화양상은 동부와 녹두 전분이 유사하였고, 팥 전분의 냉각점도와 고구마 전분의 최고점도가 높았으며, 밀 전분은 전반적으로 점도가 낮았다. 아밀로오스의 분자량 분포는 묵 형성 전분이 팥이나 밀보다
Some physicochemical properties and molecular structure of cow pea, mung bean and acorn starches(mook-forming starches) and red bean, wheat and sweat potato starches(mook-unforming starches) were investigated. Amylose contents of cow pea, mung bean and acorn starch were higher than the others. Cow pea starch was similiar to mung bean starch in gelatinization characteristics by Brabender amylogram but cold viscosity of red bean starch and peak viscosity of sweet potato starch were especially high. Whereas viscosity of wheat starch was low in whole temperature range. Amylose molecules of larger molecular size
