Food grade titanium dioxide is really common and not so nano. The titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it's not really a nanomaterial either. Nanoparticles are typically smaller than 100 nanometers in diameter.Yet most of the particles in food grade titanium dioxide are larger than this.itanium dioxide (which isn't the same thing as the metal titanium) is an inert, insoluble material that's used as a whitener in everything from paper and paint to plastics.
âDunkinâ Brands, the parent company of the Dunkinâ Donuts chain, has agreed to remove titanium dioxide, a whitening agent that is commonly a source of nanomaterials, from all powdered sugar used to make the companyâs donuts,â As You Sow states in a release.unkinâ Brands claims that the exact ingredient used in their powdered sugar doesnât fit in the ânanoparticleâ definition as outlined by the FDA. And the FDA notes that titanium dioxide, as long as itâs under 1 percent in the food, should be safe to consume.
