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.
It is considered to be an inert and safe material. The US FDA allows food products to contain up to 1% titanium dioxide without the need to include it on the ingredient label, as long as the substance added conforms to stringent levels of purity.s part of this update, products from a peer review paper published the previous year were included â a study, published in the journal Environmental Science and Technology, reported an analysis of nearly 90 food products for the presence of the material titanium dioxide.
