china titanium dioxide producers

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

The majority of the world's production of titanium dioxide goes into the manufacturing of paints, coatings, plastics, paper, and ink. As a pigment, it boasts high refractive index properties that provide exceptional opacity and brightness, making it ideal for enhancing the durability and appearance of products. Moreover, titanium dioxide's stability and ability to withstand high temperatures mean it can be used in exterior paints designed to resist fading caused by sunlight exposure.
