胡麻油溶剂残留量测定方法优化OA
Determination method optimization for residual solvent in flaxseed oil
[目的]优化胡麻油溶剂残留量测定方法.[方法]使用顶空气相色谱法,采用含6%氰丙基—苯基的甲基聚硅氧烷毛细管柱分离测试胡麻油样品.[结果]六号溶剂的线性相关系数为0.999 9,平均加标回收率为91.0%～102.3%.胡麻油原干扰峰不在六号溶剂目标峰时间段出峰,其他常见植物油也无峰面积较大的干扰峰.[结论]气相色谱条件可用于常见植物油溶剂残留量的测定.
[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.
