Materials and articles in contact with foodstuffs - Certain epoxy derivatives subject to limitation - Determination of BADGE, BFDGE and their hydroxy and chlorinated derivatives in food simulants
This European standard describes a method for the determination of BADGE, BFDGE and their reaction products in food simulants: distilled water, 3 % w/v aqueous acetic acid, 10 % v/v aqueous ethanol solution and olive oil or sunflower oil.A high performance liquid chromatography (HPLC) method is employed based on reversed phase HPLC and fluorescence detection. The method is capable of determining BADGE and its derivatives at a minimum level of 0,05 µg/ml food simulant. BFDGE and its derivatives can be determined at a minimum level of 0,1 µg/ml food simulant.Direct HPLC analysis of the migration solutions may result in chromatograms difficult to interpret,
