The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).
Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
The so-called “barrier effect” makes it possible to achieve good anti-corrosion protection in primers.
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.
Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.
The Colour of Barium Sulphate and Its Suppliers
The main food categories contributing to dietary exposure of E171 are fine bakery wares, soups, broths and sauces (for infants, toddlers and adolescents); and soups, broths, sauces, salads and savoury based sandwich spreads (for children, adults and the elderly). Processed nuts are also a main contributing food category for adults and the elderly.
The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.
Various titanium-rich minerals, including ilmenite and rutile, can serve as starting materials for the production of highly purified Titanium Dioxide. The predominant method employed in Titanium Dioxide production is the chloride process. In this process, the mineral, along with coke and chlorine, undergoes a reaction within a fluidized bed, resulting in the formation of primarily titanium tetrachloride and carbon dioxide. Subsequently, the titanium tetrachloride undergoes purification and conversion to Titanium Dioxide. Another method involves treating ilmenite with sulfuric acid to manufacture the chemical.
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.
