Exposure (EFSA, 2017)

Exposure to furan – Main contributors: • Infants ( highest exposure ): Ready-to-eat meals • Other children: Grains and grain-based products • Adults: Coffee ( highest concentrations ) Inclusion of alkyl furans in the assessment can significantly increase the exposure: e.g. , 2-methylfuran concentration in coffee is about 4-times higher than furan concentration
