검정콩을 이용한 기능성 간장을 제조하기 위한 연구의 일환으로 원료 콩의 증자조건에 따른 검정콩 전통간장의 숙성후, 질소화합물 및 유리아미노산의 함량을 조사하였다. 총질소 함량은 308.3∼925.0 mg%로 나타났으며, 상압이나 스팀에 비하여 가압으로 증자한 간장의 총질소 함량이 아주 낮았고, 스팀증자 시간이 길어짐에 따라 총질소 함량이 증가하였다 아미노태질소 함량은 133∼451.5 mg%로 나타났으며, 상압(451.5 mg%)이 가장 높았으며
Total nitrogen(TN) contents in all samples were in the range of 308.3 to 925.9 mg% and TN value of kanjang prepared with high pressure(HPK)-heated bean was lower than that of normal pressure(NPK) and steam(SPK)-heated bean. TN content was slightly increased according to the heating time of bean. Amino type nitrogen(AIN) contents in all samples were in the range of 133 to 451.5 mg％ and AIN value of NPK(451.5 mg%) was higher than that of HPK(133∼171.5 mg%) and SPK(178.9∼224 mg%). Ammonia type nitrogen(AON) contents in all samples were in the range of 23.5 to 142.0 mg% and AON value of HPK was lower than that of HPK and SPK. Free amino acid(FA) contents in all samples were in the range of 133 to 451.5 mg%, and then FA content of NPK was higher than that of SPK(178.9∼224 mg%) and HPK(133 ∼171.5 mg%). Lightness(L) value of Hunter color in all samples were in the range of 45.13 to 49.08 and was similar with each other. Redness(a) and yellowness(b) value were in the range of 25.30∼34.43 and 52.55∼74.13, respectively.
