Abstract

Changes of pH, acidity, pretense activity and microorganism on Korean traditional seasonings using soy sauce (T1), red pepper paste (T2) and soybean paste (T3) were investigated during storage at $1{\pm}1^{\circ}C$ for 21 days. The pH and pretense activity of soybean paste were significantly (p<0.05) higher compared to those for soy sauce and red pepper paste during storage. The acidity of red pepper paste were significantly (p<0.05) higher compared to those for soy sauce and soybean paste at 1, 7 and 14 days of storage. The total plate counts and Lactobacilli spp. of soy sauce were significantly (p<0.05) lower compared to those for soybean paste and red pepper paste during storage. The Escherichia coli of red pepper paste and soybean paste were not detected during storage.

본 연구는 간장(T1), 고추장(T2) 및 된장(T3) 소스를 제조한 후 $1{\pm}1^{\circ}C$에서 21일간 저장하는 동안 pH, 산도, 단백질 분해효소 활성도 및 미생물의 변화를 관찰하고자 수행하였다. pH는 된장 소스가 간장과 고추장 소스에 비해 현저하게 높았다. 산도는 고추장 소스가 간장과 된장 소스에 비해 저장14일까지 현저하게 높았다. 단백질 분해효소 활성도는 된장소스가 간장과 고추장 소스에 비해 현저하게 높았다. 총 균수는 간장 소스가 고추장과 된장 소스에 비해 현저하게 낮았고, 저장기간이 경과함에 따라 감소하였다. 대장균은 간장 소스가 저장 1일에 검출되었으나 저장 7일부터는 검출되지 않았고, 고추장과 된장 소스는 저장 1일부터 검출되지 않았다. 유산균수는 간장 소스가 고추장과 된장 소스에 비해 현저히 낮았고, 모든 양념에서 저장기간이 경과함에 따라 감소하였다.
