Abstract
An analytical method for the determination of the specific migration o f aziridine (ethyleneimine) into food simulants at trace levels is des cribed. The method comprises a two-phase (aqueous-organic solvent) der ivatization procedure with 4-fluorobenzoyl chloride, using propyleneim ine as an internal standard. The derivatization reaction is accomplish ed very quickly and the organic layer containing the derivatized imine is analysed by capillary gas chromatography using selective nitrogen detection (nitrogen-phosphorus detector). The detection limits of the method were lower than 5 mu g/kg in the food simulant.
