Abstract

Kochujang was prepared with various concentrations of Maesil extracts (0, 1, 2, and 5%) and the physicochemical characteristics of Maesil extracts added Kochujang ('Maesil Kochujang') were investigated during aging of 100 days. pH decreased slightly during aging. Titratable acidity, on the other hand, increased with aging, reaching at the highest level at the 40 days of aging and then decreased slowly. The changes of moisture content were complicated in the beginning, but after 60 days it increased slowly. The water activity decreased but salt concentration increased consistently in all samples during aging. L* and a*-values decreased during aging and L*, a*, and b*-values decreased significantly with high amount of Maesil extract in the sample. Soluble solid contents increased slowly while reducing sugar contents increased for up to 40 days and then decreased. Amino nitrogen contents increased steadily after 40 days of aging and they reached at $230.00{\sim}246.00mg%$ upon 100 days of aging.

매실추출액의 농도를 달리 첨가하여 "매실고추장"을 제조하고 실온에서 100일간 숙성시키면서 품질특성을 비교하였다. 고추장의 pH는 숙성 중 전반적으로 감소하였고 적정 산도는 증가하는 경향을 나타내었다. 수분함량은 숙성 60일까지 다소 증감을 보이다. 숙성후기에는 증가한 반면 수분활성도는 숙성기간 중 감소하는 경향을 나타내었다. 식염은 숙성기간 중 증가하였고, 대조구가 매실추출액을 첨가한 실험구보다 다소 높은 식염 함량을 나타내었으며 매실추출액 함량이 증가할수록 식염의 함량은 다소 낮았다. 고추장의 L*, a*값은 숙성 중 감소하였고, b*값은 숙성초기 감소하다가 숙성 60일째 값이 크게 증가하다가 그 이후에는 감소하는 경향을 나타내었다. 매실추출액을 첨가한 고추장이 대조구에 비해 L*, a*, b*값 모두 낮게 나타났고 매실추출액 첨가량이 증가할수록 L*, a*, b*값이 현저하게 감소하였다. 당도는 숙성이 진행됨에 따라 서서히 증가하였고, 환원당은 숙성초기에는 증가하여 숙성기간 40일에 최고치에 달한 후 서서히 감소하였다. 아미노태 질소는 숙성초기에 증감하다 숙성 40일 이후에는 지속적으로 증가하여 100일 숙성 후에는 $230.00{\sim}246.00mg%$ 수준을 나타내었다.
