| Objective To establish a method for simultaneous determination of ten preservatives in beverage by gas chromatography.Methods The analytes in beverage were extracted by ethyl acetate,and then were separated with FFAP capillary column and detected with FID detector.Results Linear ranges of the method were wide with correlation coefficients varying from 0.9986~1.000.Recoveries and relative standard deviations (RSDs)were in the range of 84.5%~113% and 1.59%~10.32% respectively.The limits of detection were in the range of 0.26~3.2mg/L.Conclusion The method is simple,efficient,cheap,eco-friendly and is suitable for simultaneous determination of 10 preservatives in beverage. |
