Objective: The purpose of this study was to develop sensitive, selective, and valid methods for the detection of bisphenol A (BPA) contamination inbeverage samples using gas chromatography (GC)-flame ionization.Methods: The optimized analysis system employed a long HP-1 capillary column (30 m, inner diameter 0.25 mm, film thickness 0.25 μm), gradientcolumn temperature (150°C–260°C at 10°C/min), and nitrogen as a carrier gas (1 mL/min). Samples were prepared for analysis using ethyl acetateas the extraction solvent.Results: This method yielded a linearity coefficient of 0.9998, while the limit of detection (LOD) and limit of quantitation (LOQ) were 0.287 μg/mL and0.956 μg/mL, respectively. All validation parameters, including linearity, selectivity, accuracy, precision, LOD, and LOQ, meet recognized acceptabilitycriteria. Contamination analysis showed that one of the three beverage brands tested contained 2.4090 μg/mL BPA, and contamination was evenhigher after heating.Conclusion: BPA contamination may occur in canned beverages, especially under improper storage conditions. This GC-based BPA detection systemmay be useful for the detection of BPA contamination in consumer beverages.
