Commercial baby food samples available on the Brazilian market (n = 31) were analysed for furan content using a gas chromatography-mass spectrometry method preceded by solid-phase microextraction. A limit of detection of 0.7 microg kg(-1), a limit of quantitation of 2.4 microg kg(-1), mean recoveries varying from 80% to 107%, and coefficients of variation ranging from 5.6% to 9.4% for repeatability and from 7.4% to 12.4% for within-laboratory reproducibility were obtained during an in-house validation. The levels of furan found in the samples were from not detected to 95.5 microg kg(-1). Samples containing vegetables and meat showed higher furan levels as compared with those containing only fruits. An exposure assessment showed furan intakes up to 2.4 microg kg(-1) body weight day(-1) (99th percentile) for babies fed exclusively with commercial baby foods. Margins of exposure obtained from intakes estimated in this work indicated a potential public health concern.
对巴西市场上的商业婴儿食品样本(n = 31)进行了呋喃含量分析,采用固相微萃取前的气相色谱-质谱法。检测限为 0.7 微克/千克,定量限为 2.4 微克/千克,平均回收率在 80%至 107%之间,重复性的变异系数在 5.6%至 9.4%之间,实验室内部重现性的变异系数在 7.4%至 12.4%之间。在内部验证过程中获得了这些结果。在样本中发现的呋喃含量从未检出到 95.5 微克/千克不等。与仅含水果的样本相比,含有蔬菜和肉类的样本中呋喃含量更高。暴露评估显示,仅食用商业婴儿食品的婴儿的呋喃摄入量高达 2.4 微克/千克体重/天(99%百分位)。从本工作中估计的摄入量得出的暴露边际表明存在潜在的公共卫生问题。
