Quantitative Analysis of Ethyl Carbamate in Korean Alcoholic Beverages by Chromatography with Mass Selective Detection

In order to determine the contents of ethyl carbamate in Korean traditional alcoholic beverages and general beverages, GC/MS-SIM method was used after extraction of beverages with dichloromethane. The contents of ethyl carbamate in Korean traditional alcoholic beverages, non-distilled alcohol, and whisky were detected in the range of $4.6-50.2{\mu}g/L$, $27.8-45.4{\mu}g/L$, and $24.8-55.1{\mu}g/L$, respectively. The recoveries were ranged from 83.3 to 104.8 %. The values of relative standard deviation were ranged from 1.8 to 14.8 % and the detection limit was $0.3{\mu}g/L$.

GC/MS 를 이용한 한국 주류 중의 Ethyl Carbamate 정량

한국 고유의 전통주 및 일반 알코올 음료에 대한 ethyl carbamate 의 함량을 알아보기 위하여 국내에서 시판되고 있는 술을 dichloromethane 용매로 추출한 후 GC/MS-SIM방법에 의해 분석하였다 분석결과 ethyl carbamate는 한국고유의 전통주에 $4.6-50.2{\mu}g/L$ 비 증류주에 $27.8-45.4{\mu}g/L$ 위스키에는 $24.8-55.1{\mu}g/L$ 함유되어 있음을 알 수 있었다. 회수율은 83.3-104.8 %의 값을 얻었고, 상대표준편차는 1.8-14.81% 검출한계는 $0.3{\mu}g/L$이었다.
