| Abstract: | A method for determination of 3-chloro-1,2-propandiol (3-MCPD) in hydrolysed vegetable proteins (HVP) using capillary gas chromatography (CGC) with flame ionization detection (FID) was described. Samples were derivatized with phenylboronic acid and extracted with hexane prior to determination by GC/FID, 1,2-propandiol was used as the internal standard. The procedure was simple, quick and accurate. The lowest limit of detection was 0.2 mg/kg. The recoveries were 92.0% to 108.0% with the coefficient of variation of 3.1% to 5.1%. |
