담금방법을 달리하여 제조한 메주, 고오지, amylase, protease 고추장의 유기산과 지방산을 분석한 결과는 다음과 같다. Citric acid, malic acid, lactic acid, succinic acid, formic acid, oxalic acid, acetic acid가 고추장에서 검출되었다. Citric acid는 $450{sim}565$ mg%로 가장 많은 량으로 나타났고 다음이 lactic acid, malic acid 등이었다. 유기산 총량은 담금직후에 메주고추장이, 90일후는 고오지 고추장이 높았으나 시험구간의 함량차이는 적었다. Oleic acid, palmitic acid, lauric acid, linoleic acid, myristic acid, stearic acid가 고추장에서 검출되었다. Oleic acid는 $68.59{sim}75.38%$로 가장 높은 함유율을 나타냈으나 각시험구간의 지방산 조성비율은 차이가 거의 없었다.
Organic acids and fatty acids of four different Kochujang prepared with different mashing methods were determined by HPLC and GC. Citrate, malate, lactate, succinate, formate, oxalate and acetate were identified. Citrate was found as a major organic acid ($450{sim}565$ mg%) followed in decreasing order by lactate and malate. Total organic acid content of Meju Kochujang was the highest at the initial fermentation time, while that of koji Kochujang was higher than any other one after 90 days of fermentation. There was a little change of total acid among the treatments. Oleic acid was a major fatty acid ($68.59{sim}75.38%$) during the fermentation of Kochujang. There was no significant change of fatty acids during the fermentation and among the treatments.
