Abstract
Normal phase LC with gradient elution enabled the analysis of a broadened range of oligomers of BADGE (Bisphenol‐A diglycidyl ether) and Novolak compounds in canned foods, such as sea foods in oil, meat products and soups. A major component released from Bisphenol‐A resins was identified as the cyclo‐ (Bisphenol‐A monoglycidyl ether) dimer and was commonly present in foods at concentrations of around 1 mg/kg. For the epoxy Novolaks, concentrations of the three‐ to six‐ring compounds often far exceeded those of BFDGE (Bisphenol‐F diglycidyl ether) and reached 20 mg/kg in foods. A two‐step acylation is proposed for the detection of epoxy components.Keywords
