Abstract

The purpose of this study was to provide a basis for the management of traditional Doenjang by analyzing characteristics of volatile compounds in local Doenjang certified as a traditional food. The main compounds in Doenjang were acids, esters, aldehydes, and pyrazines, whereas relatively high intensities of acetic acid, ethyl alcohol, benzaldehyde, ethyl acetate, ethyl 2-methyl butanoate, 2,5-dimethyl pyrazine, and tetramethylpyrazine were detected among identified compounds. The analysis revealed that the composition of basic volatile compounds in Doenjang was similar, but isovaleric acid, 2-methylbenzaldehyde, tetramethylpyrazine, benzaldehyde, ethyl alcohol, ethyl caprylate, furfural and butanoic acid can serve as marker compounds for quality evaluation since they were specifically abundant in only some kinds of Doenjang. As a result, the quality status of Doenjang certified as a traditional food was determined by constructing a database of the volatile compounds, which can be suggested as a quality control method.

본 연구는 국내 전통식품 품질인증 된장에 대한 휘발성 향기 성분 특성을 분석하여 전통된장의 과학적 관리를 위한 기초 자료를 마련하고자 수행되었다. 이를 위해 수집된 전통된장을 대상으로 headspace SPME-GC/MS 분석을 실시하고 전반적인 국내 유통 전통된장의 휘발성 성분 패턴을 분석하였다. 연구 결과 총 59종의 성분이 동정되었고 각각 acids 8종, alcohols 8종, aldehydes 8종, esters 15종, ketones 2종, phenols 4종, pyrazines 9종, miscellaneous 5종으로 확인되었다. 전통된장의 주요성분은 acid류, ester류, aldehyde류 및 pyrazine류였으며, 그중 acetic acid, ethyl alcohol, benzaldehyde, ethyl acetate, ethyl 2-methyl butanoate, 2,5-dimethylpyrazine 및 tetramethylpyrazine이 동정된 전통된장의 휘발성 성분 중 비교적 높은 강도를 차지하였다. 주성분 분석 결과 대부분의 전통된장은 기본적인 휘발성 향기성분의 조성이 유사한 것으로 나타났으나 isovaleric acid, 2-methylbenzaldehyde, tetramethylpyrazine, benzaldehyde, ethyl alcohol, ethyl caprylate, furfural, butanoic acid 성분들이 일부 된장에서 특이적으로 높아 이들 성분이 전통된장의 품질지표가 될 수 있을 것이라 보였다. 본 연구 결과는 전통식품 품질인증 된장에 대한 휘발성 향기 특성을 데이터베이스화하여 품질 현황을 파악하고 지속적인 품질관리를 통한 제품 발전의 방안으로 제시될 수 있을 것이다.
