Abstract : Objective: A rapid analytical method was developed for the determination of 4 kinds of artificial musk (musk ambrette, galaxolide abbalide, musk xylene, and ketone musk) in beverages by gas chromatography-mass spectrometry (GC/MS). Methods: Totally 4 artificial musk residues were extracted from the samples (mango juice, tea, coffee, strawberry milk and other beverages different substrates) with Hexane, and then detected by GC/MS with external standard method. Results: The linearity was obtained among 0.1-1.0 µg/mL with correlation coefficients above 0.9999. The recoveries of all artificial musk were in the range from 81.3% to 97.5% at the spiked levels of 20, 200, and 400 µg/kg in beverages, and the relative standard deviations (RSDs) were between 2.5%-7.5%. The limits of detections (LODs) of the 4 kinds of musk were 5.0 µg/kg. Conclusion: The method is simple, rapid and accurate, and suitable for the simultaneous analysis and evidence of 4 artificial musk in beverages.
