目前食用植物油中残留溶剂的检测方法为填充柱顶空气相色谱法[1],采用六号溶剂做标准,标准溶液用N,N-二甲基乙酰胺(简称DMA)做溶剂配制。DMA具有毒性,使用DMA对检验人员健康不利,标准六号溶剂较难购买,且操作复杂。为此,本文探讨了用新鲜机榨油作溶剂,石油醚为标准物质,采用毛细管柱顶空气相色谱法,克服了
At present, the detection method of residual solvent in edible vegetable oil is packed column headspace gas chromatography [1], using No. 6 solvent as standard, and standard solution is prepared by using N, N-dimethylacetamide (DMA) as solvent. DMA is toxic, the use of DMA adversely affects the examiner’s health, and the standard VI solvent is harder to buy and the operation is complicated. To this end, this paper explores the use of fresh machine oil as a solvent, petroleum ether as a reference material, using capillary column headspace gas chromatography to overcome
