A method based on solid phase extraction followed by derivatization and gas chromatography-mass spectrometry analysis was validated for the determination of bisphenol A (BPA) in canned food products. This method was used to analyze 78 canned food products for BPA. Concentrations of BPA in canned food products differed considerably among food types, but all were below the specific migration limit of 0.6 mg/kg set by the European Commission Directive for BPA in food or food simulants. Canned tuna products had the highest BPA concentrations in general, with mean and maximum values of 137 and 534 ng/g, respectively. BPA concentrations in the condensed soup products were considerably higher than those in the ready-to-serve soup products, with mean and maximum values of 105 and 189 ng/g, respectively, for the condensed soups and 15 and 34 ng/g, respectively, for the ready-to-serve soups. BPA concentrations in canned vegetable products were relatively low; about 60% of the products had BPA concentrations of less than 10 ng/g. Canned tomato paste products had lower BPA concentrations than did canned pure tomato products. The mean and maximum BPA concentrations were 1.1 and 2.1 ng/g, respectively, for tomato paste products and 9.3 and 23 ng/g, respectively, for the pure tomato products.
基于固相萃取衍生化和气相色谱-质谱分析的方法被验证用于测定罐头食品中的双酚 A（BPA）。该方法用于分析 78 种罐头食品中的 BPA。不同类型的罐头食品中 BPA 的浓度差异较大，但均低于欧盟委员会指令规定的 BPA 在食品或食品模拟物中的特定迁移限量 0.6mg/kg。一般来说，金枪鱼罐头产品中的 BPA 浓度最高，平均值和最大值分别为 137 和 534ng/g。浓缩汤产品中的 BPA 浓度明显高于即食汤产品，浓缩汤的平均值和最大值分别为 105 和 189ng/g，即食汤的平均值和最大值分别为 15 和 34ng/g。罐头蔬菜产品中的 BPA 浓度相对较低；约 60%的产品中 BPA 浓度低于 10ng/g。番茄酱罐头产品中的 BPA 浓度低于纯番茄酱罐头产品。番茄酱产品的平均值和最大值分别为 1.1 和 2.1ng/g，纯番茄酱产品的平均值和最大值分别为 9.3 和 23ng/g。
