It's all over the place in our environment, said Dr. Johnson-Arbor.
Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).

However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluations However, recent concerns about potential effects from nano-sized particles have led to ongoing evaluationsfood safe titanium dioxide.Some websites maintain titanium dioxide is inferior to zinc oxide, another mineral sunscreen ingredient whose core characteristics are similar to those of titanium dioxide. The reality is that titanium dioxide is a great broad-spectrum SPF ingredient and is widely used in all manner of sun-protection products. What gets confusing for some consumers is trying to decipher research that ranks sunscreen ingredients by a UV spectrum graph. By most standards, broad-spectrum coverage for sunscreen ingredients is defined as one that surpasses 360 nanometers (abbreviated as “nm” - how the sun’s rays are measured). Titanium dioxide exceeds this range of protection, but depending on whose research you read, it either performs as well as or slightly below zinc oxide.
Titanium dioxide A1 adopts good oxidation process, composite inorganic coating and organic treatment, and has the characteristics of excellent particle size distribution, high brightness and high weather resistance. It is recommended for high gloss and high weather resistance coatings, inks and outdoor polymer materials.
In 2016, the European Food Safety Authority, or EFSA, assessed titanium dioxide and determined that the evidence available at the time didn’t conclusively point to any health problems for consumers.
