The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).
Conclusion
Nano, or ultrafine, TiO2 comprises primary particles sized less than 100nm. In this grade, titanium dioxide is transparent (colourless) and boasts improved UV scattering and absorbing properties compared with larger particle-size pigmentary TiO2.
5. Geographical Availability Depending on the location of businesses, suppliers with a good logistical network can ensure timely delivery and availability of stock. Local suppliers may also provide cost advantages compared to international counterparts due to reduced shipping fees.
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.
This food chemical has been used in food for more than half a century, but recent studies show it may be harmful.
Does not work with hydrogen sulfide and alkaline solutions. It is easy to decompose in the presence of acid to produce hydrogen sulfide gas. It is easily oxidized in the air and deteriorates after moisture. Whiteness and hiding power are strong.
However, the use of titanium dioxide has also raised concerns about its potential impact on human health and the environment. Some studies have suggested that titanium dioxide nanoparticles may have harmful effects when inhaled or ingested. Manufacturers of titanium dioxide are therefore taking steps to minimize the risk of exposure and develop safer products.
Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.
