What we know about Titanium Dioxide (E171).

Dr. Sharif Sharifi

When the clocks ticked over into 2020, France’s suspension on the whitener titanium dioxide came into effect. The ban is the result of a French study that found that titanium dioxide nanoparticles are absorbed by the intestine and passed into the bloodstream of animals after oral exposure. The conclusion for human consumption of the product, is that there is insufficient evidence to guarantee that titanium dioxide is safe to use as a food additive.

That said, exposure to nanoparticles of titanium dioxide and other additives has previously been shown to interfere with the immune system and cause cell damage. Last year, a University of Sydney study found that titanium dioxide has impacts on the gut microbiota, which could lead to diseases including IBS and colorectal cancer.

So far in Australia titanium dioxide is still an approved food additive, and has been used in consumer products for decades.

If you’re concerned about titanium dioxide, be aware that the ingredient is rarely listed by name - more commonly you’ll see titanium dioxide listed as the additive ‘E171’, or as ‘Colour(171)’. It’s mainly used to lighten and brighten foods, so be vigilant with products where whiteness is a typical feature - such as sugar-coated candies, white sauce, and synthetic chewing gums.

At AFPI, our Mast Chew and Mast Chew ZERO chewing gums are free from titanium dioxide. We know our customers care about what they’re putting in their bodies and giving to their families. That’s why we’re proud to make additive-free options available so you don’t have to choose between avoiding additives and enjoying our products.
