The aim of this paper is to offer a method based on headspace gas chromatography-mass spectrometry technique (US FDA 2006) in-house validated and used to estimate furan concentrations in jarred baby food samples purchased from the Spanish market. The validation was performed according to ISO 17025 and EFSA requirements and the results obtained (LOD 0.05 µg.kg-1; LOQ 4 µg.kg-1, lowest validated level; 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 µg.kg-1 (rice and chicken samples) and ≤ LOQ (fruit-based samples). The mean concentrations values found for the different matrices were 5.0, 37.8, 25.2, 33.8 and 30.5 µg.kg-1 for fruits, 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.
