Bisphenol a diglycidyl ether (BADGE) and related compounds in fish products packed in cans or multilayer laminated film packages from the Japanese market

Abstract

Bisphenol A diglycidyl ether (BADGE) and related compounds (dimer, trimer, bisphenol F diglycidyl ether (BFDGE), 3-ring Novolac glycidyl ether (NOGE), and BADGE-2HCl adduct) in 26 canned fish and 2 fish products in multilayer laminated film packages from the Japanese market, having migrated from the can coatings or films, were determined by normal-phase HPLC. BADGE was detected in 12 samples of canned fish. The highest concentration was 0.9 mg/kg. The total amount of BADGE, dimer and trimer in the canned fish reached up to 15 mg/kg. NOGE was detected in 4 samples, at concentrations between 1.2 and 6.9 mg/kg. BADGE-2HCl adduct was detected in 2 samples of canned fish. Of the 2 fish product samples in laminated film packages, 1.1 mg/kg of BADGE and 1.2 mg/kg of its dimer were detected in one sample. These compounds in the fish product foods were considered to have migrated from the glue of the laminated films.
