Abstract

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.

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.
