Abstract

Analysis method was presented for the simultaneous determination of nine bisphenol A related compounds such as bisphenol A (BPA), phenol, p-tert-butylphenol, bisphenol A diglycidyl ether (BADGE), BADGE· 2H2O, BADGE·2HCl, bisphenol F diglycidyl ether (BFDGE), BFDGE·2H2O and BFDGE·2HCl migrated from inner coatings of metal food cans by high performance liquid chromatography (HPLC) with fluorescence detection. The method was validated by examining the linearity of calibration curve, the limit of detection (LOD), the limit of quantification (LOQ), recovery and uncertainty. The migration tests of nine BPA related compounds were carried out with four food simulants; deionized water (DW), 4% acetic acid, 50% ethanol and n-heptane. There was not any compound detected in DW, 4% acetic acid and 50% ethanol at 60oC for 30 min and n-heptane at 25°C for 60 min. BPA and phenol were migrated into 4% acetic acid and 50% ethanol at 95oC for 30 min. The concentrations were ranged from 0 to 10.77 μg/L of BPA and from 0 to 2.35 μg/L of phenol. Canned foodstuffs mostly have long-term shelf life. We investigated migration of nine BPA related compounds according to the variation in storage periods (0~90 days) and temperatures (4, 25 and 60°C). All compounds were not founded during 90 days at 4°C and 25°C, respectively. However BPA and BADGE·2H2O were founded in DW and 4% acetic acid at 60°C. The migration levels of BPA and BADGE·2H2O were close to the value of LOQ, respectively and did not change significantly as storage period. It was founded from results that the migration of BPA related compounds from metal food cans was controlled to a safe level.
