- Titanium dioxide, or E171, is commonly used as a coloring additive in food products like candy, chocolate, coffee creamer, cake decorations, chewing gum and even vitamin supplements.
- The primary function of Anatase Titanium Dioxide in food is as a coloring agent. Its intense whiteness can effectively brighten and whiten foods such as powdered sugar, confectionery, and dairy products. By adding small amounts of this compound, manufacturers can achieve a more visually appealing product that attracts consumers. Moreover, its high refractive index means that it can be used to add a glossy finish to certain foods, further enhancing their appeal.

- The properties of TI02 powder are nothing short of remarkable. Its ability to withstand extreme temperatures, combined with its chemical stability, makes it an ideal candidate for applications ranging from paint manufacturing to the production of advanced ceramics. In paints, TI02 powder acts as a pigment, imparting a brilliant white color that brightens and enhances the final product's aesthetic appeal. Moreover, its high refractive index boosts the paint's hiding power, allowing for more efficient coverage and reducing the need for additional coats.
Flavoring Agents
- Furthermore, titanium dioxide has been shown to possess antioxidant properties

Hiding power
In a small study published in the European Journal of Nutrition in 2020, researchers examined the effects of several food additives, including titanium dioxide, along with artificial sweeteners and cleaning products by testing the fecal samples of 13 people. Titanium dioxide was among the samples that “induced significant shifts in microbiome community structure.” The growth of the bacterium species belonging to C. leptum, which has been shown to decrease in patients with inflammatory bowel disease, “significantly decreased in the presence of … titanium dioxide” among other additives and sweeteners tested.
Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.


Pendant longtemps on a reproché au lithopone sa mauvaise tenue à l'extérieur, due à la dégradation photolytique du sulfure de zinc et/ou à la présence de traces de chlore, provoquant un noircissement du revêtement. Même si la recherche a permis d'éradiquer en grande partie ce problème, on réserve son emploi dans les peintures intérieures pour les raisons suivantes :
Titanium dioxide has many purposes in both food and product development.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
The principal natural source of titanium dioxide is mined ilmenite ore, which contains 45-60 percent TiO2. From this, or an enriched derivative (known as titanium slag), pure TiO2 can be produced using the sulphate or chloride process.
Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).
Titanium dioxide is a mineral that’s used as a white coloring in a variety of products, including sunscreens, cosmetics, paints, and plastics. The pigment grade is also known as titanium white, pigment white 6, or CI 77891; it's the whitest and brightest of all known pigments.
English name: Lithopone
Health Canada's Food Directorate recently completed a “state of the science” report on titanium dioxide (TiO2) as a food additive. Food-grade TiO2 is a white powder made up of small particles that has been permitted in Canada and internationally for many years as a food additive to whiten or brighten foods. Food-grade TiO2 has long been considered safe in Canada and in other countries when eaten as part of the diet.
