S. Abrantes et al., APPLICATION OF CAPILLARY ELECTROPHORESIS IN MIGRATION STUDIES OF FOODCONTACT MATERIALS .1. SUBSTITUTED PHENOLIC ADDITIVES, HRC. Journal of high resolution chromatography, 20(5), 1997, pp. 270-274
A method has been developed to determine 11 phenolic antioxidants in t
he food simulants distilled water, 3% acetic acid. and 15% ethanol, us
ing micellar capillary electrophoresis (MCE). All the phenols could be
analyzed within 35 min, The analytical recovery from spiked simulants
was 80 to 119% except for 2,6-di-tert-butyl-4hydroxytoluene (BHT) and
octyl gallate, which could not be recovered from 3% acetic acid simul
ant, Calibration graph correlation coefficients for the 11 phenols wer
e 0.982 to 0.999, Limits of detection (LoDs) were from 2.8 to 8.6 mg/L
. These LoDs are well below European Union migration limits for these
substances. It is concluded therefore that MCE offers a rapid and reli
able analysis for the control of migration from plastics intended for
food contact which employ these phenols as antioxidants.
