Abstract

Response surface methodology (RSM) was used for the analysis and optimization of the production process of Kochujang added with Maesil extract. The process variables were the amount of Maesil extract ($0{\sim}8%$) and red pepper powder ($6{\sim}10%$). pH and all color characteristics (L*-, a*-, and b*-value) decreased but titratable acidity and water activity increased with the addition of Maesil extract. Amino nitrogen content appeared to decrease with the addition of red pepper powder. The highest sensory flavor score was obtained when 2.20% Maesil extract and 8.62% red pepper powder were blended, the highest sensory taste score with 6.63% Maesil extract and 9.50% red pepper powder, and the highest sensory color score with 7.80% Maesil extract and 8.62% red pepper powder respectively. The point chosen as representative of the optimal area corresponds to $X_1=3.60%,\;X_2=10%\;and\;X_1=4.08%,\;X_2=9.96%$ for physicochemical and sensory quality, respectively.

중심합성계획에 의한 반응표면분석법을 이용하여 매실추출액 첨가 고추장의 이화학적 특성 및 관능적 품질의 최적배합조건을 설정하고자 매실추출액 및 고춧가루 첨가량에 따른 품질특성의 변화를 살펴보았다. 첨가 매실추출액이 증가할수록 pH는 감소하였고, 적정산도의 경우는 매실추출액과 고춧가루의 증가에 따라 증가하였으며 특히 매실추출액 증가에 따른 산도의 증가가 뚜렷했다. 고춧가루의 첨가량이 증가할수록 아미노태질소 값이 감소하는 경향을 나타내었고 매실추출액이 증가할수록 수분활성도는 증가하였으며, 수분함량의 경우 매실추출액이 증가할수록 완만히 증가하다 약간 감소하는 경향을 나타내었다. 색도의 경우 매실추출액이 증가할수록 모든 색특성(L*, a*, b*-value)이 감소하는 경향을 나타내었다. 향의 경우 매실추출액 및 고춧가루의 배합비율이 각각 2.20%, 8.62%일 때, 맛의 경우 6.63%, 9.50%, 색의 경우 7.80%, 8.62%일 때 최고의 관능평점을 얻었다. 모든 품질특성에서 고춧가루의 함량보다는 매실추출액 첨가량에 따른 영향이 크게 나타났다. 최적화 결과, 이화학적 품질특성 부분에서는 매실추출물이 3.60%, 고춧가루 첨가량이 10%일 때 최적의 공정조건을 나타내었으며 관능적 품질특성 부분에서는 매실추출물이 4.08%, 고춧가루 첨가량이 9.96%인 경우 최적인 것으로 나타났다.
