초록

시중에서 판매되는 국내외 14종의 쌀된장의 품질 특성을 분석하고자 아미노태 질소 함량, 암모니아태 질소 함량, 환원당 함량, Protease활성, Amylase활성 및 일반 세균수를 조사하였다. 그 결과, Protease 활성은 국내 제품인 KRD-1 (415.16 unit/g)과 KRD-2 (380.57 unit/g)의 값을 나타내었고, 일본제품은 510.14~695.10 unit/g으로 분석되었다. Amylase 경우, KRD-1 (46.52 unit/g)과 KRD-2 (7.41 unit/g)의 활성을 보였으며, 일본제품은 3.97 unit/g~53.65 unit/g의 활성을 나타내었다. 특히, JRD-1 (46.29 unit/g), JRD-7 (53.65 unit/g) 및 JRD-8 (50.71 unit/g)로 다른 시료에 비해서 높은 활성을 나타내었다. 환원당의 경우 14종의 쌀된장 중 JRD-10~12시료에서 각각 0.52%, 0.55%, 0.54%의 값을 나타내었다. 아미노태 질소 함량의 경우, 국내산 제품은 KRD-1 (207.61 mg%)과 KRD-2 (316.10 mg%)의 함량을 보였고, 일본제품은 209.45 mg%~426.45 mg%의 함량을 보였으며, JRD-1 (426.45 mg%), JRD-7 (303 mg%) 및 JRD-9 (352.94 mg%)의 높은 값을 나타내었다. 국내산 쌀된장은 KRD-1 (19.22 mg%)였으며, 일본 쌀된장은 1.11 mg%~29.25 mg%의 함량을 보였고 특히 JRD-1 (29.25 mg%), JRD-2 (10.75 mg%), JRD-10 (14.44 mg%), JRD-12 (13.06 mg%)로 높은 값을 나타냈다. 일반세균수의 경우, 국내산 쌀된장인 KRD-1과 KRD-2의 경우 5 Log CFU/g이상의 균수가 측정되었으며 일본산 쌀된장의 경우JRD-2 (3.82 Log CFU/g)를 제외한 모든 샘플에서 균이 검출되지 않았다. 본 연구결과는 국내외 시판되는 쌀된장의 품질특성에 대한 정보를 제시하였다.
