| Abstract: | A method to determine the residual solvent in edible vegetable oils using headspace-gas chromatography is established. The main components of solvent No.6 were separated completely under the optimized equilibrium temperature and equilibrium time conditions of the headspace auto-sampler.The amount was quantified by an external standard method. The linear relationship was satisfied from 2.0 to 100.0 mg/kg. The average spiked recoveries at three levels were in the range of 98.2%~99.2% and the relative standard deviations(n=6) were less than 2%.With features such as simpleness and accuracy, this method is suitable for the determination of residual solvent in edible vegetable oils. |
