mica and titanium dioxide factories

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.
4.Used as a white pigment, the hiding power is second only to titanium dioxide, but stronger than zinc oxide. The hiding power increases as the ZnS content increases, and the light resistance also improves, but the acid resistance decreases.
Fig. 6. AOPP measured on samples of MSSA with: A) 0.2 mg/mL P25TiO2NPs; B) 0.02 mg/mL P25TiO2NPs; C) 0.2 mg/mL VitaminB2@P25TiO2NPs; D) 0.02 mg/mL VitaminB2@P25TiO2NPs after 3 h of irradiation (red) and 6 h (blue). SD <1 (error bars too small to be seen) and p < 0.05 between C-D and A-B.
