When used in food specifically, titanium dioxide is known as an additive called E171 and can be found in products like candy, chocolate, coffee creamer, cake decorations, chewing gum and even vitamin supplements. E171 is often used as coloring additive in foods, to lend the processed item a natural whiteness and opacity — such as in Skittles candy, where it's used as a white base to help give the candies their signature bright, colorful hue.

Are there any other products where you use titanium dioxide?

TiO2 is a white pigment that is commonly used in the production of paints, plastics, and paper. It is known for its brightness, opacity, and durability, making it an ideal choice for products that require a high level of whiteness and coverage. TiO2 is also used in sunscreen lotions and cosmetics to provide protection against harmful UV rays. In addition, TiO2 is used in the food industry as a food additive to enhance the appearance of products such as candies and confectionery.
