Abstract: A method was developed for the determination of tertiary butylhydroquinone (TBHQ) in foods with gas chromatograpy-selected mass spectrometry (GC-MS). TBHQ was extracted and concentrated from samples by ethyl acetate, then dissolved by saturated acetonitrile and cleaned up by n-hexane. TBHQ was thus determined and the content of TBHQ was assayed. The limit of quantitative detction(S/N)>10 is 0.05 mg/kg and the recovery is in the range of 90%~102% and the relative standard deviation is 1.10%.
