Abstract

The quality characteristics of dough with lotus root powder were investigated. As the content of lotus root powder increased, doughs showed higher water absorption, lower stability and longer development time than control as measured with a farinograph. Extensibility decreased with the increase of lotus root powder. As the addition of lotus root powder increased, the doughs has higher gelatinization temperatures and maximum viscosities than control as measured by amylograph. And the pH of the dough also increased by the increase of lotus root powder.

연근 분말 첨가가 제빵 적성에 미치는 영향에 대하여 반죽의 물리적 특성과 품질의 특성을 파악하고 기능성과 물리적인 면을 고려한 배합비율을 알아보았다. 파리노그램의 반죽 특성을 보면 수분 흡수율은 첨가량이 증가할수록 감소하였다. 반죽 형성시간은 연근 첨가량이 많아질수록 길어졌다. 익스텐소그래프에 나타난 반죽의 신장도는 대조군에 비해 첨가군은 점점 감소하였으나, 신장 저항도와 최대 저항도는 첨가량이 증가할수록 점차 증가하였다. 아밀로그래프에서는 호화개시온도는 대조군보다 첨가랑이 증가할수록 높아졌으며 최고 점도도 첨가군이 대조군보다 높았다. 반죽의 pH는 첨가량이 증가할수록 증가하였다.
