매실분말과 매실농축액을 각각 첨가한 고추장을 만들고 숙성하면서 품질 변화를 고찰한 결과 숙성 기간이 경과함에 따라 모든 시험구의 수분 함량이 대체적으로 증가하였으며, 숙성 8주에는 고추장 담금시에 비하여 정도 높았다. 매실분말과 매실농축액을 첨가한 시험구의 pH는 각각의 대조구보다 낮았으며, 첨가량이 많을수록 더 낮은 값을 나타내었다. 고추장이 숙성되어감에 따라 모든 시험구의 pH는 점차 낮아졌으나 대조구와 매실분말 및 매실농축액 첨가구 사이의
Powder, or a concentrate, of maesil (Prunus mume) were used in the making of kochujang, and were added to kochujang at 0.5 or 1.0% (w/w). Kochujang fermented with maesil powder lower moisture content than did samples fermented with maesil concentrate. Moisture content slowly increased during fermentation, and was higher than the initial value after 8 weeks of fermentation. Kochujang fermented with maesil powder or maesil concentrate showed lower pH values and higher total acidities than did the control. The total microbial count was , and yeast and mold levels were , as kochujang fermentation commenced. Microbial load reached a maximum by 4 weeks of fermentation, and decreased thereafter. L (lightness), a (redness) and b (yellowness) values of kochujang gradually decreased during fermentation. Compared to methanol extracts of kochujang, water extracts and ethanol extracts showed higher free radical scavenging abilities at the initial stage of fermentation. Control, and samples with 0.5% (w/w) maesil powder or maesil concentrate, attained higher scores in sensory evaluation tests than did samples with higher maesil levels, and were not significantly different at P>0.05 as determined by Duncan's multiple range test.
