The European Food Safety Authority (EFSA) has completed its re-evaluation of all food colours permitted for use in the European Union before 2009. For the final re-evaluation, EFSA's experts concluded that available data on titanium dioxide (E 171) in food do not indicate health concerns for consumers. But they recommended new studies be carried out to fill data gaps on possible effects on the reproductive system, which could enable them to set an Acceptable Daily Intake (ADI).

 

Over the past seven years, EFSA's Panel on Additives and Nutrient Sources Added to Food (ANS) has re-assessed the safety of 41 food colours, taking into account all available scientific studies and data. Where possible, the Panel has established or updated an ADI for each substance.

 

Available toxicological data on titanium dioxide do not indicate adverse effects via oral ingestion. While the ANS Panel was unable to set an ADI for titanium dioxide because of data limitations, using the margin of safety approach, they concluded that dietary exposure does not pose health concerns. The experts highlighted, however, the need for new research to fill data gaps on potential effects of titanium dioxide on the reproductive system.
