Abstract

This study was conducted to develop the efficient system for starch hydrolysis suppression using rutin, quercetin and dietary fiber through the statistical mixture design. The three components were replaced with wheat flour at the level of 10% and the mixed gel with three components was characterized by in vitro starch digestion. The mixture design was applied by simplex-centroid experimental model. The quadratic model (R2=0.86) was well fitted and the obtained regression equation indicated that the significant positive effects was observed in the quercetin and fiber mixture. Based on the statistical results, the best mixing ratio of quercetin and fiber was 72: 28 that led to the lowest predicted glycemic index (pGI). Their interactions on the pGI of starch digestibility were clearly visualized in the 3D surface plot. These results suggested that the mixture of quercetin and fiber interact strongly with wheat flour, consequently retarding starch hydrolysis by 15%.

본 연구는 루틴, 퀘르세틴, 식이섬유가 전분 소화율에 미치는 영향을 통계적 혼합물 설계방법을 이용하여 확인하고자 하였다. 세 가지 성분들은 모두 농도가 증가함에 따라 전분소화 지연 효과가 나타났으며, 그 중에서도 퀘르세틴과 식이섬유가 함께 섞였을 때 가장 높은 지연 효과를 보였다. 이 혼합물 설계는 simplex-centroid 실험설계법을 이용하였고, 최적 모델은 quadratic 모델에서 나타났다. 이때 얻어진 회귀방정식을 통하여 유의한 상승효과를 확인할 수 있었다. 최적화 통계 방법을 사용하여 혼합비를 분석한 결과 퀘르세틴과 식이섬유가 72: 28 비율에서 전분 소화 지연 효과가 최대로 나타나는 것을 확인하였다. 전분소화에 대한 영향을 3차원 표면 도표로 시각화하여 나타내었으며, 이 결과로 퀘르세틴과 식이섬유의 상호작용으로 인하여 전분 소화를 15% 이상 지연시키는 것을 확인할 수 있었다.
