气相色谱-质谱联用法测定食品中3-氯丙醇酯及缩水甘油酯
Determination of 3-Chloropropanol Esters and Glycidol Esters in Food Products by Gas Chromatography-Mass Spectrometry
摘要
Abstract
A method was established for the simultaneous determination of 3-chloropropanol esters (3-MCPDE) and glycidol esters (GE) in different types of oil and lipid food products by gas chromatography-mass spectrometry (GC-MS).Optimizations on extraction,transesterification,derivatization and the chromatographic conditions of GC-MS of samples were completed.Limits of quantitation (LOQs) of the method for four types of food products,i.e.vegetable oils,milk powder,fried and puffed foods and bakery foods,were 100,25,125,20 μg/kg,respectively,the total mean recoveries were in the range of 81.2％-109％ with the relative standard deviations (RSD,n =6) of 0.77％-7.3％ and the correlation coefficients(r) higher than 0.999.Moreover,the 3-MCPDE and GE contents in 30 oil and lipid food products were determined to be in the range of no detected-8.04 mg/kg.The developed method could meet the demand for routine food inspection,in particular for the quantitative and qualitative determination of 3-MCPDE and GE in oil and lipid foods with its high efficiency,high sensitivity and strong workability.关键词
