Food additive E171: ANSES reiterates its recommendations for consumer safety

The food additive E171, which consists of Titanium Dioxide  (TiO2) particles, mainly in nanoparticle form, is used in many different food products. Following the expert appraisal work it conducted in 2017, ANSES was asked in February 2019 to review the most recent studies on the oral toxicology of E171 and to update its recommendations. On completion of this expert appraisal, the Agency concluded that it had not obtained any new information to resolve the uncertainties regarding the safety of the additive E171. Pending a better characterisation of the hazards and risks posed by E171, it reiterates its general recommendations on nanomaterials, aimed mainly at limiting the exposure of workers, consumers and the environment, by promoting safe alternatives with equivalent effectiveness.
