Research Abstract |
The purpose of this work is simultaneous quantification of monochloropropanediols (MCPDs) and glycidol in fats and oils of which the risks are discussed toward health. In this work, the effective gram scale synthetic method of 2-MCPD was developed and interconversions of 2-MCPD, 3-MCPD, and glycidol each other in the course of DGF standard method C-VI 18(10) were observed by NMR spectroscopy. Addition of glycidyl fatty acid ester into actual soybean oil sample reveals that about 95% of glycidol generated from the ester was converted into 3-MCPD and the rest of that was converted into 2-MCPD. Over-estimation could be a problem at the quantification of fat sample containing relatively larger amount of glycidol.
