Abstract

This study was carried out to analyse the physicochemical characteristics of soybean pastes with the sword beans and general soybean pastes. There was no difference in contents of general component (moisture contents, crude ash, crude fiber, crude fat) among the soybean pastes, but contents of crude protein was higher in J1, J2 compared to the others. Amylase activity was higher in J3, J4 adding the rice, and protease activity was higher in J1, J2 that has higher soybean contents than the others. Reducing sugar contents was higher in J3, J4 that has high amlyase activity with value of 8.53${\pm}$0.45% and 8.36${\pm}$1.05%, and amino-type nitrogen contents was higher in commercial soybean paste K5, K6 than other soybean pastes with value of 668.34${\pm}$4.11 mg% and 642.64${\pm}$2.05 mg% respectively.

작두콩 된장의 품질특성을 알아보기 위해 재래식 방법으로 제조한 된장에 작두콩을 8.0% 첨가한 된장(J2)과 재래식 쌀 된장에 작두콩을 6.0% 첨가한 된장(J4)을 제조하여 시판된장(K1-K6) 및 일반 재래 된장(J1, J3)과의 시험분석을 하였다. 수분, 회분 등 일반성분결과, 시료간 차이는 없었으나, 조단백질 함량과 protease 활성은 다른 시료에 비해 콩함량이 높은 J1과 J2가 높게 나타났으며, amylase 활성과 환원당 함량은 쌀을 첨가하여 제조한 J3과 J4가 다른 시료보다 높게 나타났다. 또한 아미노태 질소 함량은 시판된장인 K5와 K6에서 각각 668.34mg%와 642.64mg% 함량을 나타내어 다른 시료보다 높게 측정되었으며, 색도는 시료간에 유의적인 차이가 있었으며 작두콩 첨가가 색도에 큰 영향을 미치지는 않았다.
