e171 in food factories

One of the key benefits of using R-906 rutile TiO2 is its ability to improve the overall quality of printed materials. By providing excellent whiteness and opacity, R-906 enhances the visual appeal of printed products, making them more eye-catching and professional-looking. Additionally, the chemical stability of R-906 ensures that printed materials maintain their color and appearance even under harsh environmental conditions, such as high humidity and exposure to sunlight.

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

One of the most well-known uses of titanium dioxide powder is in the production of paints and coatings. Titanium dioxide is a popular pigment due to its excellent opacity, brightness, and durability. It is commonly used in architectural paints, automotive coatings, and other applications where colorfastness and weather resistance are important. Suppliers who can provide a consistent, high-quality titanium dioxide powder are essential for the paint and coating industry to produce top-notch products.

The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column  and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.
