Abstract: | Summary A fluorimetric-detection RP-HPLC method is developed for the separation and quantification of bisphenol A diglycidyl ether (BADGE), bisphenol F diglycidyl ether (BFDGE), its hydrolysis and chlorohydroxy derivatives, and NOGE and BADGE oligomers. This method was applied to test an epoxy resin used as a coating for food contact packaging materials with two different heat treatments in the curing process. Migration of these compounds was evaluated in three food simulants: 3% (w/v) acetic acid, 10% (v/v) ethanol, rectified olive oil and also in acetonitrile. A simple extraction procedure was also applied to obtain olive oil extracts. Quantification was performed by using external calibration, and correlation coefficients were greater than 0,996 and the limit of detection (LOD) was 0.02 mg L–1 for all substances. HPLC-MS method was applied to confirm derivatives and oligomers identity.Presented at: International Symposium on Separation and Characterization of Natural and Synthetic Macromolecules, Amsterdam, The Netherlands, February 5–7, 2003 |
