报道了双酚A(BPA)从环氧涂层罐头表面向婴儿配方奶粉浓缩液的迁移。本研究中调查的未稀释浓缩物中双酚A的含量范围为0.1至13 ppb(Ppb)，这是通过固相萃取/高压液相色谱结合荧光检测进行检测，并通过气相色谱与质量选择检测进行确认。采用30度镜面反射/透射率的傅里叶变换红外光谱技术筛选环氧涂料配方罐。
Migration of bisphenol A (BPA) from epoxy-coated can surfaces to infant formula concentrates is reported. Levels of BPA in the undiluted concentrates surveyed in this study range from 0.1 to 13 parts per billion (ppb) as determined by solid phase extraction/high-pressure Liquid chromatography with fluorescence detection and confirmation by gas chromatography with mass selective detection. Fourier transform infrared spectroscopy with 30 degrees specular reflectance/transmittance was used to screen formula cans for epoxy coatings.
