Abstract
본 연구에서는 염처리 음식물의 냄새성분 배출특성을 파악하고자 스팸을 조사대상으로 선정하여 시간경과에 따른 휘발성화학물질의 발생특성을 파악하고자 하였다. 이를 위하여 총 9 일 동안 5 회에걸쳐 시료를 채취 후 GC/MS 시스템과 GC/PFPD 시스템을 이용하여 분석하였다. 분석 결과 연구기간 동안 환원황, 알데하이드, 케톤류의 냄새성분들이 주로 발생하는 것으로 나타났다. 신선기에 해당하는 E-0,E-1일은 hydrogen sulfide의 농도가 각각 1465 μg/m3 (60.0%), 455 μg/m3 (28.0%)로 가장 높게 나타났다. OAV (악취활성값) 또한 E-0 일은 19.4 (78.3%), E-1 일은 6.02 (41.7%)로 가장 높게 나타났다. 부패기에해당하는 E-3, E-6, E-9일에는 ketone류의 acetone이 각각 451 (43.2%), 369 (64.2%), 1150 μg/m3 (70.2%) 로 나타났다. 그 뒤를 이어 2,3-butanedione이 각각 17.6 (1.68%), 16.1 (2.80%), 179 μg/m3 (10.9%)로 나타났다. 이들 성분의 실질적인 냄새 기여도를 OAV로 비교하면, acetone은 0.001 (0.01%)이하로 미미한수준이지만, 2,3-butanedione은 1.14-11.6 (14.5-76.2%)으로 높게 나타났다. 본 연구의 결과, 신선기에는 환원황 그룹, 신선기와 부패기의 중간 시점에는 알데하이드 그룹, 부패기에는 케톤 그룹 성분들이 가장 중요한 냄새 요인으로 작용하는 것을 확인하였다.
