| 摘 要： | 通过质谱法确定了食用植物油溶剂残留中除正己烷以外的3种主要六碳烷烃,并以正己烷为标准物质,采用顶空进样-气相色谱法测定食用植物油中的溶剂残留量.研究了食用植物油中溶剂残留量的定性和定量测定方法;比较了3种六碳烷烃与本检测方法的相对标准偏差进行了比较.结果表明,方法加标回收率为97.98%-98.88%,相对标准偏差在2.5%-3.4%之间,最低检出限为0.001mg/L,方法简单、准确.

| Abstract: | The residual solvent in edible oil was determined by HS-GC with hexane be standard solution. The three main kinds of hexanealkyls in edible oil were found. The range of recovery is 97. 98%-98. 88% with RSD of 2. 5%-3. 4%. The detection limit is 0. 001mg/L. The method is simple and accurate. |
