매실을 건조한 분말과 농축액을 각각 0.5%, 1.0% 첨가한 된장을 만들고 숙성하면서 품질특성의 변화를 고찰하였다. 된장의 숙성 기간이 경과함에 따라 수분함량은 다소 증가하였으며, 특히 숙성 2주의 수분함량 증가가 다른 기간에 비하여 현저하였다. 된장 숙성중 전질소의 함량은 큰 차이를 보이지 않았으나 아미노태 질소 함량은 숙성 기간 중 지속적으로 증가하였으며, 숙성 2주 동안의 증가가 현저하였다. 매실분말 및 매실 농축액 첨가구에 비하여 대조구
Different amounts of powder and concentrate (0.5% and 1.0%) of Prnus mume were added to doenjang and were examined during fermentation at . Moisture and amino nitrogen content were gradually increased, regardless of the amount of powder and concentrate of Prnus mume (PCP). A rapid increase in moisture and amino nitrogen was shown at initial 2 week of fermentation. Control showed a higher amino nitrogen content and microbial load (yeast and mold) than samples with PCP. Reducing sugar content was rapidly decreased after 2 weeks, but was plateaued after 4 weeks. Color (L, a and b) of doenjang had the highest value at 4 weeks, but was decreased thereafter. Weter extracts from samples with PCP were lower in radical scavenging activity than that of control, but methanol extracts and ethanol extracts were generally higher than that of control. Based on On sensory evaluation of doenjang after 6 weeks, control 1 was better than other treatments in color, aroma and taste. Significant difference was not observed among control 1, control 2 and samples with 0.5% PCP.
