Furan (C₄H₄O) is a volatile compound formed during the Maillard reaction and was recently classified as a possible human carcinogen (group 2B) by the International Agency for Research on Cancer. It has been reported to occur in various canned and jarred foods that undergo heat treatment. The aim of the present study was to optimise the sample preparation for furan analysis using solid phase microextraction-gas chromatography/mass spectrometry (SPME-GC/MS), according to the food matrix. We also performed the monitoring and risk assessment of furan in various food products. The optimised fibre exposure temperatures, time and amount of sample of liquid, semi solid and paste state foods were 5g (ml), 50°C, and 20min, respectively. The level of furan in canned meat (32.16ng/g) was the highest among the samples studied. The furan levels in canned fish, canned vegetable, nutritional/diet drinks, canned soups and jarred sauces were 29.40, 22.86, 7.28, 18.54 and 21.52ng/g, respectively. Furan concentrations in baby food products were between 3.43 and 97.21ng/g. Exposure estimates (14.59ng/kgbw/day) of baby foods was the highest among all the tested food samples. However, the exposure estimate of baby foods was lower than that prescribed by the US FDA.
