Abstract
When fats are irradiated, hydrocarbons contained one or two fewer carbon atoms are formed from the parent fatty acids. A method to detect radiation-induced hydrocarbons consists of the extraction of fat from beef, pork and chicken, separation of hydrocarbons with a florisil column and identification of GC/MS methods. When beef, pork and chicken were irradiated, pentadecane, 1-tetradecene, heptadecane, 1-hexadecene, 8-heptadecene, 1,7-hexadecadiene, 6,9-heptadecadiene and 1,7,10-hexadecatriene were formed from palmitic, stearic, oleic and linoleic acids. Concentrations of the produced hydrocarbons tended to increase linearly with the dose levels of irradiation. Concentrations of hydrocarbons produced by
쇠고기, 돼지고기, 닭고기를 방사선 조사시켜 생성된 hydrocarbon류의 양을 비교 분석하였다. 쇠고기와 닭고기의 지방추출은 n-pentane과 isopropanol 혼합용매 (3 : 2, v/v)를 사용하였다. 돼지고기는 가열 융해시켜 지방을 추출한 뒤 florisil로 충전한 column을 이용하여 hydrocarbon류를 분리하였으며, GC-FID 및 GC/MS 분석기기로 성분을 확인하였다.
