된장과 순된장에 멸치, 마늘, 고춧가루, 파를 부재료로 첨가하여 찌개로 가열 조리할 때 첨가재료에 의하여 생성된 향기성분 및 그 향기성분 생성에 영향을 미치는 인자를 알아보고자 하였다. 그리고 관능검사를 통하여 된장찌개의 향기성분의 특성에 관여하는 주요성분을 알아보았다. 된장의 향기성분에는 aldehyde류와 ester류의 향기성분이 많았으나 순된장의 향기성분에서는 된장의 것보다 sulfur compound류와 pyrazine류 향기성분의 수와 그 함량이 더 많았다. 순된장의 향기성분 수는 된장의 것보다 많았으나 멸치, 마늘, 고춧가루, 파를 부재료로 첨가하여 가열한 순된장찌개에서는 된장찌개보다 오히려 더 적은 수의 향기성분이 생성되었다 순된장찌개에서 검출된 다양한 pyrazine류는 관능검사의 결과 순된장찌개의 구수한 향에 기여하지 않았다. 된장찌개와 순된장찌개에서 상대적으로 그 함량이 많으며 전체적인 품질의 선호도 및 향기성분 선호도에 관여하는 향기성분은 aldehyde류, alcohol류, ketone류였다.

The volatile compounds of soybean pastes(home made soondoenjang, commercial doenjang) were classified into basic, acidic and neutral fractions by dynamic headspace method. The fractionated flavor isolates were analyzed and identified by gas chromatography mass spectrometry. Each peak area of the flavor components was quantified at its ratio to the peak area of internal standard. Sixty one compounds from home made soondoenjang, and forty three compounds from commercial doenjang were identified. The different distribution of volatile compounds between the two soybean paste samples was observed. Ten pyrazines and benzothiazole were identified in the basic fraction of home made soondoenjang. On the other hand, trimethylpyrazine was the only one of nitrogen containing compounds in the commercial doenjang, which was made from soybean(28.3%), wheat(22.2%) and alcohols. The factors which influenced the levels of these identified compounds were considered to be the starting materials of soybean paste. Alcohols, esters and aldehydes in the neutral fraction of both samples were seemed to be characterisitic soybean paste flavor and showed much higher quantities than those of the basic or acidic fractions. Furfural in the commercial doenjang was the highest content (45.28ppm) among all of the compounds identified in the samples.
