Furan was quantified using the internal standard method. The calibration points were prepared as follows: 2.5g of MQ-water and 2.5g of 20%NaCl was weighed into a headspace vial. Different volumes (50–250ll) of furan working standard solutions and a constant volume (50ll) of internal standard working solution were added. Finally, MeOH was added to ensure that corresponding volume of solvent was added to all vials. The calibration curve covered the concentration range of1 .9–93. 6lgkg1 furan in baby food.
