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.
Foodstuffs in developed countries contain increasing quantities of microparticles such as titanium dioxide. Titanium dioxide is used by the millions of tons as a whitening or brightening pigment to make white-colored paint, but also as an additive to make white-colored food.It s added to food so much so that people eating conventional diets may be ingesting a trillion particles of titanium dioxide every day.wo potential risk factors are animal protein and nanoparticles, such as titanium dioxide. Of all dietary factors, animal protein from meat and fish is most associated with a higher risk of inflammatory bowel disease.
