Abstract

Sensory analysis and quality properties were performed on post-aged doenjang (fermented soybean pastes) in order to elucidate the contribution of citrus, green tea and cactus powder to their sensory evaluation. The doenjang added citrus fruits, green tea and cactus powder used a concentration of 0, 3 and 7% (w/w) at 4, 20, $30^{\circ}C$ respectively and analyzed the proximate composition, pH, salt, mineral and amino acid contents after 60 days. Moisture and protein changes during ripening did not show any significant difference. The pH showed lower in the doenjang added citrus and cactus powder than no added soybean paste. The glutamic acid content of doenjang added citrus fruits showed a little decreasing value although there were no differences between samples with various addition contents. Sensory evaluation of doenjang showed that there were no significant differences in preference in the case of added green tea and cactus powder; However, the flavor significantly increased doenjang added 3% citrus powder at $30^{\circ}C$. These results showed that the preference of doenjang containing 3% citrus powder was superior to green tea and cactus powder.

생된장에 감귤, 녹차 및 선인장을 건조 분말 상태로 3%, 7% 첨가하여 $4^{\circ}C$, $20^{\circ}C$, $30^{\circ}C$ 에서 60일간 숙성 시킨 후 된장제품의 품질 특성 및 관능적 특성에 대하여 조사하였다. 일반성분을 분석한 결과, 수분은 전반적으로 55~59%로 대조구에 비하여 큰 차이가 없었고, 3% 첨가 시 수분 유지력이 우수한 것으로 나타났다. 조회분과 조단백질의 함량은 대조구에 비하여 유의한 차가 없었다. 각 된장의 조지방 함량은 대조구에 비하여 약간 증가됨을 볼 수 있었으며, 감귤, 선인장, 녹차 첨가 된장의 탄수화물의 함량은 대조구에 비하여 7% 첨가 시 유의적인 차이를 보였으며, pH는 대조구에 비하여 감귤, 녹차, 선인장 첨가 된장 모두 낮음을 보였다. 아미노산성 질소는 감귤 분말 3% 첨가 된장과 녹차 분말 첨가 된장의 $4^{\circ}C$ 숙성 시 증가됨을 보였고, 총 아미노산 함량은 감귤 분말 첨가 된장에서 대조구에 비하여 높은 함량을 보였으며, 전체적인 기호도는 감귤 3% 첨가 된장의 기호도가 상대적으로 높은 것으로 평가되었다. 이상의 결과로부터, 천연의 향미와 기능 성분을 갖는 감률 된장의 제조 가능성을 확인하였고 감귤을 활용한 제품 개발로 된장의 기호성 향상에 도움이 될 것으로 기대된다.
