고아미 부산물의 -amylase 및 cellulase 혼합처리 조건에 따른 품질특성을 비교하였다. 그 결과, 가용성 고형분 및 환원당은 -amylase 처리구(A)에서 가장 높게 나타났으며, cellulase 함량이 많아질수록 조금씩 감소하였다. 총식이섬유소 및 총당은 두 효소 농도에 따른 큰 차이를 보이지 않았다. 당류 분석 결과, 모든 처리구에서 가 모두 검출되었으며, 말토올리고당은 -amylase 처리구(A)에서 약 2,200 mg%로 가장
The quality characteristics of Goami by-product under the mixed enzyme treatment condition of -amylase and cellulase have been compared, and found the highest amount of soluble solids and reducing sugars at the -amylase treated group (A), and the contents revealed to show gradual decrease with the increase of cellulase content. The amounts of total dietary fiber and total sugars did not show large difference by both of enzyme concentration. The result of sugar analysis revealed the presence of all in all treatment groups, and the content of malto-oligosaccharide recorded the highest content of 2,200 mg% at the -amylase treatment group (A). When the quality characteristic of the hydrolyzed powders manufactured by the optimum hydrolysis condition was compared, no significant color difference was found between samples. Among the contents of dietary fibers, insoluble dietary fiber was found to present in the lowest content of 6.95% at the Goami flour (GF) and the Goami by-product powder (GBPP) and Goami by-product hydrolysate powder (GBPHP) resulted the similar content around 14% and the highest soluble dietary fibers content was found in Goami by-product hydrolysate powder (GBPHP), which was followed by in the order of Goami by-product powder (GBPP) and Goami flour (GF), but the content variation was not large. The free amino acid was found to be highest in Goami by-product hydrolysate powder (GBPHP) followed by in the order of Goami by-product powder (GBPP) and Goami flour (GF). In the sugar analysis, the Goami by-product hydrolysate powder (GBPHP) was found with all sugars by showing the highest amount of 1,800 mg% At the Goami by-product powder (GBPP), sugars were detected with about 66 mg% and malto-oligosaccharides were not detected at the Goami flour (GF). Based upon the results, the functionality of Goami by-product hydrolysate powder (GBPHP) was found to be enforced compared to Goami flour (GF) and Goami by-product powder (GBPP), which allow us to expect it to be used as the various rice processing food source.
