Abstract

Three types of doenjang were prepared with regular soybean, germinated regular soybean, and a mixture of germinated regular and black soybean. After 90 days of fermentation, pH, moisture, and salt contents of doenjang were $6.01{\pm}0.01-6.72{\pm}0.01$, $53.78{\pm}0.22-57.99{\pm}0.11$, and $14.17{\pm}0.06-15.03{\pm}0.21%$, respectively, showing slight differences according to soybean germination. Amylase and protease activity of doenjang changed similarly during fermentation in all samples. Amino-type nitrogen and free amino acid content of germinated black soybean doenjang after 90 days of fermentation were $1256.21{\pm}1.86$ and 994.46 mg%, respectively, which were higher than those of other samples. A sensory evaluation of germinated regular soybean doenjang showed the highest scores for color, taste, and overall acceptability. These results suggest that high sensory quality doenjang can be prepared using germinated regular soybean and a mixture of germinated regular soybean and black soybean.

발아 대두 및 발아 검정콩의 첨가에 따른 된장의 품질 특성에 미치는 영향을 알아보기 위하여 발아 대두 및 발아 대두와 발아 검정콩을 7:3의 비율로 혼합하여 만든 메주를 이용하여 된장을 제조하였다. 대조구로는 발아하지 않은 대두로 발효한 메주를 이용하여 대두된장을 제조하여, $25^{\circ}C$에서 90일간 발효시켰다. 된장의 수분, pH, 염도와 같은 이화학적 특성은 모든 처리구에서 발효기간에 따라 유사한 경향으로 변화하여, 발효 90일 각각 $53.78{\pm}0.22-57.99{\pm}0.11%$, $6.01{\pm}0.01-6.72{\pm}0.01$, 그리고 $14.17{\pm}0.06-15.03{\pm}0.21%$를 나타내었다. 아미노태 질소 및 아미노산 함량은 발아검정콩된장에서 발효 90일 각각 $1256.21{\pm}1.86$, 994.46 mg%로 유의적인 차이(p<0.05)를 보이며 높게 나타났다. 발효 90일된 된장의 관능평가를 실시한 결과 발아대두된장에서 색과 맛 등의 항목에서 기호도가 높게 평가되었으며, 전반적 기호도에서 대두된장에 비하여 발아대두된장 및 발아검정콩된장의 관능적 특성이 우수한 것을 확인하였다. 연구결과로부터 발아 대두 및 검정콩을 첨가하여 제조한 된장은 발아하지 않은 대두를 이용하여 제조한 된장과 이화학 및 효소화학적 특성에는 차이가 없으나 아미노태 질소 및 아미노산 함량이 높고 관능적 특성이 우수한 된장을 제조할 수 있을 것으로 생각된다.
