Abstract

The purpose of this study was to investigate whether the electronic nose can be applied as a primary screening procedure to detect ethanol in gochujang for halal certification. First, ethanol content in 25 traditional gochujang was measured by gas chromatography with flame ion detector, widely accepted as the conventional method of alcohol detection. The content ranged from 0.14 to 2.7%. Then, 8 gochujangs selected from among the initial 25 samples were analyzed by electronic nose. Similar ethanol content patterns were observed between the two detection methods. In addition, commercial gochujang products were examined by electronic nose to ensure that they complied with the required ethanol standard of the halal certification authority. Consequently, it was confirmed that electronic nose analysis can be applied as a primary screening method for halal certification.

본 연구에서는 할랄 인증을 위한 고추장 중 에탄올 분석 시 1차 스크리닝 절차로서 전자코가 적용 가능한지를 알아보고자 하였다. 먼저 공인된 알코올 분석법인 GC-FID를 사용하여 25개의 재래식 고추장을 분석한 결과 모든 고추장에서 에탄올이 검출되었으며 그 함량은 0.14-2.7%이었다. 이 중 8개 고추장을 선별하여 전자코 분석한 결과, 에탄올 함량이 비슷한 고추장끼리 유사한 패턴을 나타내는 것을 확인하였다. 또한 시판 고추장 2개를 대상으로 전자코 분석을 통해 할랄 인증기관이 요구하는 에탄올 기준을 준수하는지를 1차적으로 신속하게 스크리닝이 가능함을 확인하였다.
