Another important application of titanium dioxide is in the production of self-cleaning surfaces
Furthermore, titanium dioxide’s photocatalytic properties have led to its use in environmental applications

Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
Overall, the Food Directorate's comprehensive review of the available science of TiO2 as a food additive showed:
Due to its low binder requirement, lithopone provides paints with good flow and application properties. In the plastic processing industry, it is added to plastics to increase the plastic product’s UV tolerance, thus increasing its outdoor life. In the leather industry, it is one of the sulfide-based white pigments. It is also used in the production of linoleum floorings.



In a 2021, Chinese researchers examined the impact of E171 on lipid digestion and vitamin D3 bioaccessibility in a simulated human gastrointestinal tract model. They examined Vitamin D’s bioaccessibility, or the amount it was released in the gastrointestinal tract, becoming available for absorption, and found it “significantly decreased from 80% to 74%” with the addition of E171. In the experiment, E171 decreased lipid digestion dose-dependently. Researchers wrote: “The findings of this study enhance our understanding toward the potential impact of E171 on the nutritional attributes of foods for human digestion health.” The study was published in the Journal of Agricultural and Food Chemistry,
