Determination of Solvent Residues in Edible Vegetable Oils by Headspace Gas Chromatography-Tandem Mass Spectrometry
In this paper,a method for the simultaneous determination of six solvent residues in edible vegetable oil by headspace gas chromatography-tandem mass spectrometry is established.After edible vegetable oil is added to the internal standard,it is heated to gas-liquid equilibrium in a headspace sampler,and the resulting gas is separated by a gas chromatograph and entered the mass spectrometer for detection.The results show that the target substances have a good linear relationship within a certain linear range,the correlation coefficients are all greater than 0.999,the detection limits are 0.001 5 mg·kg-1 to 0.196 3 mg·kg-1,the recovery rate is 90.06％to 102.56％,and the relative standard deviation is 0.42％to 2.71％.This method is simple to operate,highly sensitive,accurate and reliable,and is suitable for the determination of solvent residues in edible vegetable oil.
