밀가루는 전분이 75퍼센트에 불과하며 전체 무게의 10퍼센트는 단백질을 함유하고 있는데, 이 단백질들은 주로 불용성인 글루텐 단백질들이다.
여러 시간 동안 가열해 글루텐을 떠내지 않는 한 액체속의 글루텐 단백질들은 밀가루로 만든 소스를 불투명하게 만들고 표면에 막을 형성시킨다.
전분은 당질이고, 글루텐은 보리, 호밀, 밀 등의 곡물에 존재하는 불용성 단백질의 혼합물이다
글루텐은 역사적으로 인류에게 중요한 단백질 공급원이었고 빵을 주식으로 하는 나라에는 여전히 딱딱하고 질긴 빵을 선호하는 경우가 많은데 이러한 빵은 글루텐 함유량이 높은 경향이 있다. 글루텐은 소화가 되면 약 33개 아미노산으로 분해되어 우리 몸에 유용하게 이용될 수 있다.
