antase and rutile type titanium dioxide

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

Another benefit of using TiO2 in paper production is its UV-blocking properties

tio2 used in paper supplier. TiO2 has the ability to absorb and reflect harmful ultraviolet (UV) radiation, which can cause paper to yellow and degrade over time. By incorporating TiO2 into paper products, paper suppliers can enhance their durability and longevity, ensuring that they remain looking fresh and vibrant for longer periods. This is particularly important for archival papers and documents that need to be preserved for generations.

TiO2 NPs appeared to be more toxic to nematode Caenorhabditis elegans than submicron-sized TiO2.  At a concentration of 1 mg/l, 7 nm particles affected its fertility and survival rate and were more toxic than 20 nm anatase particles. Similarly, Hu et al. showed that rutile particles (10–20 nm), at concentrations above 1 g/kg soil, can be bio-accumulated in earthworms, where they induce oxidative stress, inhibit the activity of cellulase and induce DNA and mitochondrial damage.
