새로운 형태의 쌀겨단무지를 개발하기 위하여, 쌀겨에 스테비아 잎 분말 및 호박산, 효모 추출물 등을 첨가한 쌀겨 단무지의 절임기간 중 이화학적 특성과 조직감의 변화를 측정하였다. 첨가물로써 대조구는 삭카린나트륨을 사용하였으며, 처리구 S1은 스테비아 잎 분말을, 처리구 S2는 스테비아 잎 분말 + 호박산, 처리구 S3은 스테비아 잎 분말+ 호박산 + 효모 분말을 사용하였다. 쌀겨단무지의 절임 90일째 pH는 호박산을 첨가한 처리구 52와 53에서
In order to develop a new rice bran danmooji, changes in physicochemical characteristics and texture of danmooji treated with rice bran, Stevia rebaudiana Bertoni leaf powder, succinic acid, or yeast extract were investigated during salting for 90 days. The PH of rice bran danmooji decreased from PH6.41 initially to pH 4.09 (control group), pH 4.10 (S. rebaudiana treatment S1), pH 3.84 (S. rebaudiana + succinic acid treatment S2), and pH 3.90 (S. rebaudiana+succinic acid+yeast extract treatment S3) after 90 days of salting. At this time, the salinities of rice bran danmooji of the S1, S52, and S3 groups were 2.32%, 1.94% and 2.15% respectively. The hardness of all groups decreased rapidly in the first 30 days of salting, and thereafter showed no changes. After 90 days of salting, the hardness of all groups was with no significant differences between groups. Redness, the a value, of the S2 and S3 groups treated with succinic acid, was lower than that of S3, whereas yellowness, the b value, of S3 treated with succinic acid and yeast extract was the highest of the three groups. Sensory evaluation of rice bran danmooji after 90 days of salting resulted in S3 attaining the highest scores for flavor, taste, texture, and overall acceptability. These results indicate nut high-quality rice bran danmooji may be prepared by addition of S. rebaudiana leaf powder, succinic acid and yeast extract to rice bran.
