Bisphenol A (BPA) is widely used in the production of polycarbonate plastics and phenolic-epoxy resins, which have a variety of applications (e.g., plastics food containers and epoxy food can coatings). One of the applications of BPA is as a starting substance in the production of epoxy resins. BPA and BPF (bisphenol F) also are used to make bisphenol A diglycidyl ether (BADGE) and bisphenol F diglycidyl ether (BFDGE), which are used as additives to scavenge hydrogen chloride in polyvinyl chloride organosols. Both epoxy resins and polyvinylchloride organosols are used frequently for the internal coatings of food and beverage cans to protect the food and beverage from direct contact with metal. The residual unreacted BPA in both epoxy and the polyvinyl chloride organosol coatings can migrate to foods, especially at elevated temperatures typically used for sterilizationin during the production process. BPA in commercial products is gradually being replaced with its analogues, such as bisphenol S (BPS), bisphenol F (BPF), bisphenol B (BPB) and bisphenol AF (BPAF).
The purpose of this study is to develop an analytical method for determining the concentration of BPA, BPF, BPS, BADGE, BFDGE and their their derivatives in canned foods using LC-MS/MS (Liquid chromatography tandem mass spectrometry). The LC method was coupled with a triple quadrupole mass spectrometer, using an ESI source in negative mode and positive mode. We validated a simple and effective procedure for analysis of slected food matrix. To represent the variety of food types evaluated in this work, nine canned food products were selected for method validation: meat, fish, corn, fruit, vegetable, sauce, beer, beverage and coffee. The linearity of standard mixture of bisphenols in the range of 2.5 ~ 725 μg/L was satisfactory with correlation coefficients (r2) of 0.999. LODs (Limit of detection) were 0.72~29.26 ng and LOQs (Limit of quantitation) were 2.18~88.67 ng. MLOQ (Method limit of detection) were 0.23~17.73 μg/kg. Intra day accuracy ranged from 75.09 to 117.77% and precision were 0.64~7.89%. Sample recoveries ranged from 70.56 to 113.6 % with relative standard deviations below 10% for spiking levels from 50 and 250 μg/kg. The results of the inter-day study, which was performed with ham and coffee for 3 days, showed an recovery of 79.13~111.74% with relative standard deviations below 9.0%. The migrating levels of bisphenols found in various caaned foods. BPA ranged N.D.~278 μg/kg, BADGE and derivatives was in the range N.D.~1525 μg/kg, BPF, BPS, BFDGE were practically not detected in the canned food.
This study was conducted to estimate the dietary exposure of bisphenols to assess there lated risk for Korean populations from the intake of bisphenols. The deterministic approach was used to estimate the dietary exposure. The average intake of BPA was 0.039% of the TDI (Tolerable daily intake) defined by the U.S. Environmental Protection Agency. The average intake of ∑ BADGE was 0.052% of TDI defined by European Food Safety Authority. The 95th percentile intakes of BPA and ∑ BADGE were 1.048% and 1.521% of TDI, respectively.
