Commercial Milk

The presence of five bisphenols, i.e., bisphenol F, bisphenol A, bisphenol B, bisphenol F diglycidyl ether, and bisphenol A diglycidyl ether, was monitored in commercial milk packed in plastic bottles marketed in Italy. The new validated method includes a solid-phase extraction procedure followed by liquid chromatography with fluorescence detection. All positive results were confirmed by liquid chromatography–tandem mass spectrometry analysis. The limits of detection and quantification and the recovery percentages indicated that the method is suitable for detecting bisphenols in milk at concentrations far below the legal limits. Of 68 commercial milk samples analyzed, no bisphenol was found in 27 samples (39.7%), and 41 samples (60.3%) contained one or more bisphenols. The bisphenol most frequently found was bisphenol F (36 samples, 52.9%) followed by bisphenol A (20 samples, 29.4%) and bisphenol B (6 samples, 8.8%). Taking into consideration the limits of detection, no sample contained either bisphenol F diglycidyl ether or bisphenol A diglycidyl ether.

A several-year survey (2000–2006) documents a continuing occurrence of bisphenol A (BPA), bisphenol A diglycidyl ether (BADGE), and bisphenol F diglycidyl ether (BFDGE), including their derivatives, migrating from packaging into food. A wide range of bisphenols levels (from traces up to hundreds µg/kg) in canned foodstuffs available at the Czech retail market was found. An analytical procedure suitable for routine monitoring of bisphenols in various matrices was validated. Crude extracts (obtained by dichloromethane extraction in ultrasonic bath) were purified by gel permeation chromatography (GPC), identification/quantification was carried out by HPLC/FLD method. Optimised procedure allowed to measure trace levels of the target analytes (LODs – 3 µg/kg) with good repeatability (RSDs – 3% at level 100 µg/kg) and recoveries exceeding 75%.

Food Simulant

Varnishes used as the inner coatings of food cans are often based on epoxy resins or vinylic organosols. The epoxy resins can be produced from bisphenol A (BPA) and bisphenol F (BPF) and they also contain bisphenol A diglycidyl ether (BADGE) of bisphenol F diglycidyl ether (BFDGE) as stabilising components. These compounds may break down during storage and also by influence of food simulants. The stability of BADGE and BFDGE was studied using reverse-phase gradient high performance liquid chromatography (RP-HPLC) with fluorescence detection (FLD). Four experiments were compared: (i) BPA solution at the concentration 3 μg/ml of each food simulant, (ii) BADGE solution at the concentration 3 μg/ml of each food simulant, (iii) BFDGE solution at the concentration 3 μg/ml of each food simulant and (iv) mixture of all bisphenols solution at the concentration 3 μg/ml of each food simulant. Distilled water, 10% ethanol, 95% ethanol and 3% acetic acid were used as food simulants. It was observed that BPA, BADGE and BFDGE were most stabile in 95% ethanol and least stabile in 3% acetic acid. Creation of hydroxy and chlorohydroxy derivatives was in each food simulant different so it cannot be predicted.
