The aim of this paper is to offer a method based on headspace gas chromatography-mass (HS-GC-MS) spectrometry technique in-house validated and use to estimate furan concentrations in jarred baby-food samples purchased from the Spanish market. The validation was performed according to ISO 17025 and European Food Safety Authority (EFSA) requirements and the results obtained (limit of detection (LOD) = 0.05 microg kg(-1); limit of quantification (LOQ) = 4 microg kg(-1), lowest validated level; relative standard deviation (RSD) = 3.1-10.5%; recoveries = 85.4-101.5%) confirm that this method is fit for the routine analysis of furan in jarred baby food control. Furan was analysed in 39 different baby-food samples and the mean levels varied between 64.6 microg kg(-1) (rice and chicken samples) and less than or equal to the LOQ (fruit-based samples). The mean concentrations found for the different matrices were 5.0, 37.8, 25.2, 33.8 and 30.5 microg kg(-1) for fruit, vegetables, meat/vegetables, fish/vegetables and dairy-containing baby foods, respectively. According to the statistical analyses, fruit-based baby-food samples had significantly lower concentrations of furan. Mean values for the other matrices were at least five times higher, and this is in accordance with the levels reported in other studies.
本文旨在提供一种基于顶空气相色谱-质谱(HS-GC-MS)技术的方法,该方法经过内部验证,可用于估计从西班牙市场购买的罐装婴儿食品样品中的呋喃浓度。验证符合 ISO 17025 和欧洲食品安全局(EFSA)的要求,所得结果(检测限(LOD)=0.05 微克/千克;定量限(LOQ)=4 微克/千克,最低验证水平;相对标准偏差(RSD)=3.1-10.5%;回收率=85.4-101.5%)证实该方法适用于常规分析罐装婴儿食品中的呋喃。在 39 种不同的婴儿食品样品中分析了呋喃,其平均水平在 64.6 微克/千克(大米和鸡肉样品)和低于或等于定量限(基于水果的样品)之间变化。不同基质的平均浓度分别为 5.0、37.8、25.2、33.8 和 30.5 微克/千克,用于水果、蔬菜、肉类/蔬菜、鱼类/蔬菜和含乳制品婴儿食品。根据统计分析,基于水果的婴儿食品样品中的呋喃浓度明显较低。其他基质的平均值至少高出五倍,这与其他研究报告的水平一致。
