Abstract

This study was to investigate the quality characteristics of brown rice mixed with white rice and boiled in hydrothermal extract of the medicinal herbs which was effective for diabetes in order to suggest a way of taking the rice everyday in Korean dietary life. The moisture content of the cooked rice was decreased with an increase of brown rice addition. The moisture content was same at Herbs extract ($H_2$). The physical properties of Herbs extract ($H_1$)and Herbs extract ($H_2$) showed a similar tendency. The hardness of the control, 100% of white rice, was lowest. The hardness was increased with increase of brown rice addition. The springiness, cohesiveness and gumminess tended to be decreased with increase of brown rice addition, while the chewiness was increased with increase of brown rice addition. In chromaticity, $H_1$ and $H_2$ revealed a similar trend. The color value L was decreased with increase of brown rice addition. The value a was decreased with increase of brown rice amount. On the contrary, the value b was increased with increase of brown rice amount. In the sensory test result of the cooked rice by using $H_1$, the appearance, taste, texture and the overall preference exhibited a tendency to decreased with increase of brown rice addition. The incase was similar to the rice cooked with $H_2$ and the overall preference showed a similar tendency, being highest at the sample added with 30% of brown rice.

한국인의 식생활에서 매일 섭취 할 수 있는 방안을 제시하기 위해 당뇨병에 효능이 있는 한약재를 이용하여 열수추출액을 제조하고 현미밥을 제조하여 그 품질특성을 연구한 결과는 아래와 같다. 수분함량은 현미의 첨가량이 증가할수록 수분함량은 낮아졌으며, $H_2$에서도 같은 수분함량을 보였다. 물성특성은 $H_1$$H_2$ 모두가 유사한 경향을 보였는데 단단한 정도(hardness)는 대조구인 백미 100%의 경우가 가장 낮았고, 현미 첨가량이 높아질수록 증가하였다. 탄력성(springiness), 응집성(cohesiveness), 점착성(gumminess)은 현미 첨가량이 증가할수록 감소하는 경향을 보였으며, 씹힘성(chewiness)은 현미 첨가량이 증가할수록 증가하는 경향을 보였다. 색도는 $H_1$$H_2$ 모두가 유사한 경향을 보였으며 L값은 현미 첨가량이 증가할수록 감소하였으며 a값은 현미 첨가량이 증가할수록 감소하는 경향을 보였고 b값은 반대로 현미 첨가량이 증가할수록 증가하는 경향을 보였다. $H_2$를 이용하여 제조한 현미밥의 관능평가 결과는 외관과 맛, texture, 전반적 기호도는 현미 첨가량이 증가할수록 감소하는 경향을 보였다. 전체적인 기호도는 $H_1$과 유사한 경향을 보여 현미 30% 첨가구에서 가장 높게 나타났다.
