초록

쇠고기 엑기스 분말로부터 방사선 조사 휘발성 화합물의 검출에 의한 새로운 검지방법의 개발을 위한 기초 자료를 마련하고자 S-PD 법, S-CD 법, P&T 법 및 LLCE 법 등 4종의 방법을 대상으로 휘발성 화합물의 추출을 위한 최적의 방법을 선정하고자 하였다. 그 결과 쇠고기 엑기스 분말로부터 탄화수소류, 알데히드류, 케톤류, 알콜류, 함황화합물류, 함질소화합물류, 방향족화합물류, 테르펜류, 푸란류 및 기타 화합물류로 구성된 106종의 휘발성 화합물이 검출되었으며, 이 중 S-PD법에 의해 62종의 화합물이 검출됨으로써 가장 많은 화합물을 나타내었고, 다음으로 P&T 법(43종), LLCE 법(38종) 및 S-CD 법(30종) 순이었다. S-PD 법은 RI 1200 이상의 휘발성이 약하며 분자량이 높은 화합물에 대한 검출능이 높았고, P&T 법은 RI 1200 이하의 화합물의 검출능이 높은 경향을 나타냄으로서, 위 두 방법은 상호보완적인 경향을 나타내었다. 한편 S-CD법에 의해 검출된 화합물은 3종을 제외하고 S-PD 법에 의해서도 검출 가능하였으며, LLCE 법의 경우는 5종의 화합물을 제외하고 S-PD 법과 P&T법을 병용할 경우 모두 검출 가능한 화합물로 구성되어 있었다. 따라서 비극성 fiber(PDMS/DVB)를 사용한 SPME 법과 P&T 법을 병용하는 방법이 쇠고기 엑기스 분말의 휘발성 화합물을 추출하기 위한 최적의 방법으로 선정되었다.

In odor to select optimum extraction methods of volatile compounds in beef extract powder(BEP) as basic data for the development of a new detection method of irradiated BEP, four extraction methods, such as solid phase microextraction with polar fiber(S-PD) and non-polar fiber(S-CD), purge and trap(P&T) and liquid liquid continuous extraction(LLCE) methods, were tested with gas chromatography/mass spectrometry method. A total of 106 volatile compounds including 22 hydrocarbons, 7 aldehydes, 6 ketones, 13 alcohols, 6 sulfur-containing compounds, 19 nitrogen-containing compounds, 6 aromatic compounds, 17 terpenes, 8 furans and 2 miscellaneous compounds were detected in BEP by four detection methods. The most compounds(62 compounds) were detected by S-PD method, followed by P&T(43), LLCE(38) and S-CD method(30). Among these methods, S-PD and P&T methods showed a complementary interrelationship to detect volatile compounds as S-PD method showed high detectabiltiy to all compound groups except hydrocarbons and ketones, which had high volatility and low molecular weight(less than RI 1200), but P&T method showed the contrary pattern to that of S-PD method. Moreover, the most of volatile compounds detected by S-CD and LLCE methods were also detectable by S-PD or/and P&T methods. Therefore, the simultaneous application of S-PD and P&T methods were selected as the optimum volatile extraction methods of BEP.
