摘要： A new method for the determination of fatty acid mono- and diesters of monochloropropanediol (MCPD) was developed. The isotopically labelled standard solution was added to the sample solution and adsorbed on the aminopropyl column. Then MCPD diesters were eluted by 6. 0 mL n-hexane and MCPD monoesters were eluted by a 6. 0 ml mixture of n-hexane/ethylacetate (7:3, V/V). The concentratrated elution were hydrolyzed with methoxide and derivatizated with phenylboronic acid (PBA) before GC/MS analysis. The method was precise and sensitive, the limits of detection for MCPD monoesters and MCPD diesters were 83. 0 mu g/kg and 142 mu g/kg, respectively. There was an excellent linear correlation (R-2 > 0. 9990) in the range of 25-500 mu g/L of MCPD monoesters & diesters (calculated by MCPD). The recovery rate of MCPD fatty acid esters spiked into edible oil and infant formula samples was in the range of 86. 5% - 104. 0%. The relative standard deviation (RSD) was from 2. 4% to 13. 2%. The method was successfully applied to the analysis of commercial edible oils and infant formula samples.
