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.
The researchers found that 36 percent of the particles in food-grade titanium dioxide are nano-sized; and then tested a variety of products for titanium dioxide and found it in dozens of products, including the ones originally listed in this post.ll of which raises the question of safety. Radically miniaturized particles are attractive to the food and textile industries for their novel properties. Nano-size titanium dioxide, for example, is used as a color enhancerâit makes white foods like yogurt and soy milk whiter, and brightens dark products like chocolate.
