The first commercial production of TiO2 began in the early 20th century, using the sulfate process. This method involved reacting ilmenite ore with sulfuric acid to produce titanium sulfate, which was then calcined to obtain titanium dioxide. However, this process had several drawbacks, including high energy consumption, generation of large amounts of waste, and release of harmful gases such as sulfur dioxide. As a result, many factories transitioned to the chloride process, which offers higher purity TiO2 and reduced environmental impact.

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
