Abstract

The physicochemical and sensory characteristics of Kongnamulguk with commercial film-packed soy sprouts from domestic cultivars were investigated. The color determination showed that the solid part of Kongnamulguk had a light green color and did not change even when cooking for 9 minutes. The solid part of Kongnamulguk was much higher in insoluble dietary fiber than soluble dietary fiber. Soluble and insoluble dietary fiber of the soy sprout tended to increase upon cooking. The acceptability of the solid part of Kongnamulguk was negatively correlated with a bean odor and flavor, and a grassy odor and flavor, but positively correlated with a nutty odor and flavor. In addition, the acceptability of the liquid of Kongnamulguk was negatively correlated with a bean odor, a grassy and bitter flavor, while it was positively correlated with a sweet flavor. These results suggest that soy sprout with a less bean odor and flavor would be highly acceptable, so it would probably be suitable for Kongnamulguk.

국산콩으로 재배한 포장 콩나물로 제조한 국의 물리화학적 특성 및 관능적 특성을 검토하였다. 콩나물 국 건더기는 수용성 식이섬유에 비해 불용성 식이섬유를 많이 함유하고 있었으며 생 콩나물에 비해 불용성 식이섬유 및 수용성 식이섬유 함량이 높았다. 콩나물 국 건더기의 자엽 및 배축은 약한 녹색도를 보여 생 콩나물의 녹화 현상은 콩나물 국을 제조하기 위해 9분 정도 가열하여도 큰 변화를 보이지 않았다. 콩나물 국 건더기는 비린 냄새와 비린 향미, 풀 냄새와 풀 향미가 약할수록, 고소한 냄새와 고소한 향미가 강할수록 선호도가 높았다. 한편 국물은 비린 냄새와 비린 향미, 풀 향미, 쓴 향미가 약할수록, 단 향미가 강할수록 높은 선호도를 보였다. 따라서 비린 냄새와 비린 향미가 약한 콩나물이 콩나물 국 제조에 적합한 것으로 생각된다.
