On June 26, 2019, the European Food Safety Authority’s (EFSA) Panel on Food Contact Materials, Enzymes and Processing Aids published a safety assessment of titanium dioxide with its surface treated with fluoride-modified alumina for use in food contact materials. The substance “is intended to be used as filler and colorant up to 25% weight/weight in potentially all polymer types” and “to be in contact with all food types for any time and temperature conditions.” The assessment concluded that the substance “does not raise safety concern for the consumer” within this intended use. The added particles were found to remain embedded in polymers and do not migrate. They were also not released upon abrasion and no transfer was seen into simulant representing solid or dry foods.
The current version of the assessment is slightly redacted, and the full version is set to be published once a decision on confidentiality is received from the European Commission.
