Trehalose가 빵용 반죽의 Rheology 특성에 미치는 영향

국문 초록 (Abstract)

Trehalose가 밀가루 반죽의 rheology에 미치는 영향을 평가하기 위하여 밀가루 대비 설탕을 6% 첨가한 것을 대조구로 하여 trehalose를 각각 2, 4, 6% 첨가하여 farinograph, viscograph, 반죽의 pH 및 총산도, 반죽의 발효팽창력 등을 분석하였다. Farinograph 분석에서 trehalose 첨가량이 증가함에 따라 반죽의 견도와 반죽형성시간은 증가하였으나, 흡수율, 안정도, 약화도, FQN 등은 감소하였다. Viscograph 분석에서 trehalose 첨가가 호화개시온도, 최고점도온도에는 영향을 주지 못하였으나, 최고점도는 trehalose 6% 첨가구에서 가장 낮았다. Trehalose 첨가량이 증가할수록 최종점도, breakdown, setback 등은 감소하였다. 120분 발효 동안 반죽의 pH 변화는 trehalose 4% 첨가구가 가장 낮았고, 반죽의 총산도는 trehalose 4% 첨가구가 가장 높았다. 반죽의 발효팽창력도 trehalose 4% 첨가구가 다른 시험구에 비해 큰 부피를 나타냈다. 이상과 같이 trehalose 첨가량을 달리한 실험에서 trehalose의 첨가는 빵용 밀가루 반죽의 rheology 특성에 영향을 주어 빵 제조에 첨가 시 빵의 부피가 크고, 부드럽고, 노화가 지연될 것으로 생각된다.

This study was conducted to evaluate the effect of trehalose on the rheological properties of bread flour dough. Farinographic and viscographic properties, pH, total titratable acidity (TTA), and fermentation power were analyzed for flour dough rheology. Flour dough containing trehalose showed greater water absorption capacity and longer development time. However the stability, degree of softening, and farinograph quality number (FQN) were lower for the trehalosecontaining flour dough, however, these factors decreased with increasing amounts of trehalose. Trehalose did not affect the beginning of gelatinization temperature and maximum viscosity temperature of flour. The maximum viscosity was the lowest with 6% trehalose, the end of final holding period, breakdown and setback values decreased with increasing amounts of trehalose. Flour dough with 4% trehalose had the lowest pH value for 120 min fermentation at 30℃, and the highest TTA value. Addition of 4% and 6% trehalose showed larger fermentation volume of dough than the control. The results suggested that trehalose positively affected the rheological properties of flour dough such as bread volume, softness, and staling delay.
