Food safety experts in the European Union (EU) have recently updated their safety assessment of TiO2 as a food additive. In Europe, TiO2 is referred to as E171, in accordance with European labelling requirements for food additives. The EU expert panel took into account toxicity studies of TiO2 nanoparticles, which to this point had not been considered relevant to the safety assessment of TiO2 as a food additive.
The Market Landscape
Because of their small size, nanoparticles may have unique physical and chemical properties. These properties may cause them to interact with living systems differently than larger materials with the same chemical composition (also known as bulk materials).
