Abstract

Doenjang made with various concentrations of salt solution such as 13, 14, 15, 16, 17, and 18% for making low-salt Doenjang. Physicochemical and sensory characteristics of Doenjang made with various concentrations of salt solution were analyzed. As a result, salt contents of Doenjang made with various concentrations of salt solution were 6.09~13.47%. Amino-type nitrogen showed a higher value when prepared with lower salt solution. The pH value increased with lower concentration of salt solution, whereas total acidity decreased with lower concentration of salt solution. The pH values and total acidity of Doenjang made with more than 16% salt solution were not statistically different. The reducing sugar content ranged from 1.39~6.30 mg/g, and higher salt content was associated with higher reducing sugar content. In the sensory descriptive analysis, Doenjang had the most salty taste at a salt concentration of 18%, whereas Doenjang at concentrations of 15%, 16%, and 17% did not show any statistical differences. In the consumer acceptance test, Doenjang made with 17% and 18% salt solution showed the highest score, followed by Doenjang made with 15% and 16% salt solution. In conclusion, the salty taste of Doenjang made with 16% salt solution might be used to make low-salt Doenjang. However, consumer acceptance of these Doenjangs was lower than that of Doenjang made with 17% and 18% salt solution.

본 연구는 전통 된장이 최근 혈전용해능력, 피부병, 혈관질환 예방, 면역강화, 항산화 효과, 항암 효과 등의 우수한 기능이 밝혀지고 있지만 식염 함량이 높다는 단점을 가지고 있어 이를 해결하기 위해 저염 된장 제조를 목적으로 염수 농도를 13, 14, 15, 16, 17, 18%로 하여 전통 된장을 제조한 후 수분 함량, 식염 함량, 아미노태 질소 함량, pH 및 적정산도, 환원당 함량을 분석하였으며, 관능평가 묘사분석을 통해 농도별 특성의 강도와 기호도를 측정하였다. 소금물 농도를 달리하여 된장을 제조하고 이화학적 분석을 실시한 결과 염수 농도가 높아질수록 수분 함량과 아미노태 질소 함량은 낮아지는 경향을 보였으나, 소금 함량과 환원당 함량은 염수의 농도가 높아질수록 높아지는 경향을 나타내었다. 각 처리구별 된장의 pH 값은 염수의 농도가 낮을수록 낮아지는 경향을 나타내었으나, 적정산도 값은 염수의 농도가 낮을수록 높아지는 경향을 나타내었다. 소금물 농도를 달리하여 된장을 제조하였을 때 정량묘사분석 결과 된장은 18%가 가장 높은 짠맛을 냈는데 15%, 16%, 17% 처리구가 18%와 짠맛에서 유의적 차이가 존재하지 않았다. 기호도 평가로 보면 된장은 17%와 18%가 유의적으로 가장 많이 선호되었다. 결론적으로 전통 된장은 된장 숙성 시작 3개월 후까지 결과를 측정한 바로는 물리화학적 특성이나 관능특성 강도 측면에서 유의차를 나타내지 않는 농도는 16% 이상의 염수로 된장을 제조하였을 때로 16%의 염수를 이용하여 전통 된장을 제조하는 것은 가능할 것으로 보인다. 그러나 기호도 평가 결과와 저장기간에 따른 변화를 고려하여야 할 것으로 판단된다.
