Why do food additive rules differ by country?
Why do food additive rules differ by country?
A food additive can have different legal status in the EU and US. Use titanium dioxide (E171) to see how assessments, permitted uses, and updates affect the answer.
Check the country, food category, conditions of use, and date. A status label without that context can mislead.
1. Why the same additive gets different answers
Regulators assess evidence and approve uses under their own laws. They may review new studies on different timelines and set different limits or labeling conditions. A substance can therefore be permitted for one food or place and not another.
The relevant question is not simply whether an ingredient is “safe” everywhere. Ask whether its use is authorized for the product and market you are checking, and what the current official record says.
2. E171: a concrete EU–US difference
The EFSA E171 assessment concluded that genotoxicity concerns could not be ruled out for titanium dioxide used as a food additive. The European Commission then withdrew its authorization for food use through EU Regulation 2022/63. EFSA assessed the evidence; the Commission changed the EU rule.
The FDA titanium dioxide information still describes permitted food-color uses of titanium dioxide under US conditions, including a limit of 1% by food weight, while noting an ongoing petition to remove that permission. This comparison reflects the cited records checked in September 2026; recheck them for current status.
3. How to compare a real label
Match the exact substance and its form, then check the food category, country, allowed quantity, labeling rules, and date. A rule for foods should not be assumed to apply to medicines or cosmetics. Product formulas and labels can change.
