현미(고아미) 비열처리 알코올발효 부산물을 식품소재로 활용하고자 cellulase처리조건에 따른 품질특성 변화를 조사하였다. 그 결과, 가수분해 온도에 따른 고아미 부산물의 가용성 고형분 및 총당은 추출온도가 높을수록 함량이 증가하였고 총식이섬유소는 약 0.67%로 비슷하게 나타났다. 환원당은 가수분해 온도 에서 가장 높은 함량을 나타내었다. 말토올리고당은 가수분해하였을 때 가장 많이 검출되었으며 maltotetraose와 maltopentao
To utilize non-heat treated alcoholic by-products of brown rice (Goami) as food sources, the quality characteristics changes according to the treatment conditions of cellulase were evaluated. Results showed that the increase of hydrolysis temperature correspondingly increased the soluble solids and total sugar amounts in the by-products of Goami, and total dietary fiber amount was found to be around 0.67% Reducing sugar concentration was the highest at the hydrolysis temperature of . Maltooligosaccharides amounts were detected to be the highest at the hydrolysis temperature of and were also, maltopentose and maltopentose were found. In the soluble solid, total dietary fiber, reducing sugar and total sugar according to the cellulase concentration, the content of hydrolysates with enzyme were higher than control, and the content of hydrolysates with enzyme was similar (6.30 and 0.69% 3,600 and 5,500 mg% respectively). The content of maltooligosaccharides was increased with the increase of enzyme concentration, and the content was similar at more than 0.6%(w/w) of enzyme concentration. The soluble solids and total dietary fiber by hydrolysis time were found to be 6.25% and 0.70%, respectively at more than 60 min. of hydrolysis. The content of reducing sugar, total sugar and maltooligosaccharides were increased with the increase of hydrolysis time, and the content was similar at more than 120min. of hydrolysis (3,800, 5,680 and 1,950 mg% respectively). Based upon these results, the byproducts of Goami are expected to be valuable as various food sources showing the highest dietary fiber and maltooligosaccharides contents by the hydrolysis at for 120 min. with the addition of 0.6%(w/w) of cellulase.
