Abstract

Volatile flavor compounds in commercial crab-like flavorants were compared by mean of solid phase microextraction(SPME) and liquid continuous extraction (LLCE)/GC/MSD methods. A total of 86 volatile flavor compounds were detected. Of these, 71 were positively identified consisting mainly of sulfur-containing compounds (13), aldehydes (3), ketones (2), esters (26), alcohols (5), aromatic compounds (3), terpenes (8), acids (2) and miscellaneous compounds (9). SPME method was more effective than LLCE method in detection of volatile components in commercial crab-like flavorants. Eight S-, N-containing compounds such as dimethyl sulfide, dimethyl disulfide, dipropyl disulfide, 3-(methylthio)propyl acetate, 3-(methylthio) propanal, 3-(methylthio) propanol, 2-methyl-3-(methylthio) pyrazine and 2-methyl-5-(methylthio) pyrazine, 8 esters such as styrallyl acetate, ethyl acetate, isoamyl acetate, benzyl acetate, ethyl pentanoate, butyl pentanoate, isoamyl pentanoate and furfuryl acetate were considered as major components in crab-like flavorants.

시판 수입 게향료 4종의 휘발성 향기성분을 SPME법과 LLCE법으로 비교 분석하였다. 동정된 86개의 휘발성 화합물 중 71개가 positive하게 동정되었으며, 이들은 함황화합물류 (13종), 알데히드류(3종), 케톤류(2종), 에스테르류(26종), 알콜류(5종), 방향족화합물류(3종), 테르펜류(8종), 산류(2종) 및 기타화합물류(9종)로 구성되었다. 인조 게향의 분석 및 동정에 있어서는 SPME법이 LLCE법에 비해 검출 감도가 매우 우수함을 알 수 있었고, 산류를 포함한 휘발성이 낮은 화합물들은 LLCE법에서만 검출되었다 제품 A-D의 특성에 따라 화합물의 조성에 차이가 있었으나 대체로 인조 게향에서는 함황 및 함질소화합물류 (dimethyl sulfide, dimethyl disulfide, depropyl disulfide, e(methylthio)propyl acetate, 3-(methylthio)propanal, 3-(methylthio)propanol, 2-methyl-3-(methylthio)pyrazine, 2-methyl-5-(methylthio)pyrazine)와 에스테르류 (styrallyl acetate, ethyl acetate, isoamyl acetate, benzyl acetate, ethyl pentanoate, butyl pentanoate, isoamyl pentanoate, furfuryl acetate) 등이 대표적인 물질로 추정되었다.
