Abstract

Doenjang, traditional Korean soybean paste without soysauce and soondoenjang that was not isolated soysauce from soybean paste were thermally processed by the addition of dry anchovy, garlic, red pepper powder and green onion. The volatile flavor components generated from doenjang soup and soondoenjang soup were studied and compared with the change in the various flavors. It was confirmed that some difference of the flavor components was found in two type of soups. Doenjang soup contained a plenty of aldehydes and ketones that revealed the savory flavor. The major flavor components in the soondoenjang soup were sulfur containing compounds that appeared the highest ratio than any other types of flavors and 10 pyrazines. On the sensory evaluation, a great number of pyrazins may be considered as a characteristic of the savory flavor of soondoenjang soup, however, it was not give the reliable result. Stepwise multiple regression analysis of two type of soups indicated that aldehydes, alcohols, ketones were contributory flavor components for overall smell preference and quality preference.

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.
