采用固相萃取-衍生化-气相色谱-质谱联用法测定罐头食品中双酚A的含量。该方法用于分析78种罐头食品中的BPA。罐头食品中BPA的浓度在不同食品类型中有很大差异，但都低于欧洲委员会关于食品或食品模拟物中BPA的指令规定的特定迁移限值0.6 mg/kg。金枪鱼罐头产品的BPA浓度一般最高，平均值和最大值分别为137和534纳克/克。分别浓缩汤产品中的BPA浓度远高于即食汤产品中的BPA浓度，浓缩汤的平均值和最大值分别为105和189纳克/克，浓缩汤的平均值和最大值分别为15和34纳克/克。分别用于即食汤。罐装蔬菜产品中的BPA浓度相对较低;约60%的产品的BPA浓度低于10 ng/g。罐装番茄酱产品的BPA浓度低于罐装纯番茄产品。平均和最大BPA浓度分别为1.1和2.1纳克/克，番茄酱产品和9.3和23纳克/克，分别为纯番茄产品。
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, hut 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.
