What it is

Titanium dioxide is a naturally occurring mineral that is processed to create a fine, white powder. It is a pigment used to make things bright white or opaque. It is made by refining titanium ore.

Why it's used

Manufacturers add titanium dioxide to food to make it appear whiter, brighter, or more opaque. It can also provide a base for other colors to stand out. It is often found in products like candy, chocolate, baked goods, and dessert toppings.

Health notes

In the United States, titanium dioxide is permitted by the FDA as a food additive. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated titanium dioxide but did not set a numeric acceptable daily intake (ADI not specified). The European Food Safety Authority (EFSA) concluded in 2021 that it could no longer be considered safe as a food additive, leading to its ban in the EU in 2022. However, the FDA continues to permit its use in food in the US.
