Abstract
[Objective] To optimize the determination method for residual solvent in flaxseed oil. [Methods] Test flaxseed oil samples are separated using a methyl polysiloxane capillary column containing 6 % cyanopropyl-phenyl by headspace gas chromatograph (HS-GC). [Results] The linear correlation coefficient of solvent No.6 is 0.999 9, and the average spiked recovery rate is 91.0 % to 102.3 %. The original interference peak of flaxseed oil does not appear within the time range of the target peak of solvent No.6. Additionally, other common vegetable oils do not have interference peaks with large peak areas. [Conclusion] HS-GC can be used to determine the residual solvent in common vegetable oils.
