W. Rauter et J. Lintschinger, Bisphenol F-diglycididylether (BFDGE) and derivates in canned food: Synthesis and analysis, DEUT LEBENS, 96(11), 2000, pp. 417-422
Bisphenol F-diglycidyl-ether (BFDGE) is added to vinylic organosol (PVC) la
cquers used for inner coatings of food cans in order to scavenge released h
ydrochloric acid during the heat treatment of the coating procedure. In the
original Varnish (NOVO-lacquer), BFDGE is present in form of different iso
mers as monomer, dimere, and oligomere. All these compounds, together with
their chlorohydroxy derivatives, were found in canned foods. Unfortunately,
pure standard compounds, which are necessary for proper analysis and toxic
ological studies, are not commercially available. Hence, in the present pap
er the synthesis and analyses (TC, GC, HPLC) of these substances is present
ed. The synthesized compounds were characterized by using mass and H-NMR sp
ectrometry. In various samples from the Austrian market the sum of the conc
entration of the above compounds exceeded frequently the official limit for
the analogue BADGE compounds of 1 mg/kg, mainly by the presence of the cho
lorhydrine derivatives.
