A method of determination of bisphenol-A in food and food packaging

摘要

PURPOSE: Provided is a detection method of bisphenol-A among foods or foods packing material which shows selective and superior sensitivity for gas chromatography(GC) or GC/mass spectrometer so that it provides optimal analysis condition for the GC/mass spectrometer. CONSTITUTION: The detection method of bisphenol-A among the foods or the foods packing material comprises the steps of: (i) extracting bisphenol-A from the foods or the foods packing material in organic solvent and treating in sodium hydroxide; (ii) reacting with 100-1400l of anhydrous acetic acid at 25-100deg.C for 5-20 minutes to produce derivatives of bisphenol-A; and (iii) analyzing concentration of bisphenol-A at the GC or the GC/mass spectrometer.
