Understanding Titanium Dioxide in Everyday Foods

Calcium carbonate, a natural mineral, whitens foods effectively without the health risks associated with titanium dioxide. Rice starch not only whitens but also enhances texture—impressive, right? These ingredients are increasingly found in products like dairy-free desserts 15 and baked goods.

Pigments through the Ages

For this reason, titanium dioxide is always blended with one or more of the other white pigments, or an inert pigment to make a suitable artists oil color. Since titanium dioxide, by itself, dries to a spongy film and zinc oxide dries to a brittle film, the two are combined in a balanced blend for better quality, professional grade titanium whites.

Obtaining higher film toughness is possible with PCC . In a paper, precipitated calcium carbonate (PCC) was substituted for TiO 2 in paint mixture at three different pigment volume concentrations (PVC). It was observed that substitution of TiO 2 by PCC depends on PVC value at which there is an optimum PCC amount.

The influence of TiO2/CC core/shell pigments on the …

The SEM photos represented in Fig. 1 showed that the core-shell particles have huge plates of calcium carbonate carrying on their surfaces smaller plates of titanium dioxide. This plate structures give high build to the matrix and since these plates are surrounded by other plates, it is assumed that the smaller plates place themselves in the voids between the calcium …

Finding Natural Color Replacements for Red No.3, Titanium Dioxide

Titanium dioxide is ideal for that usage, as well as adding pure white color. Fortunately, as with red 3, there are a number of natural alternatives to titanium dioxide, including starches and calcium-based products. Starches can replace titanium dioxide in applications where opacity is desired, although with certain limitations, Church says.

Improved opacity & TiO2 extension

Hydrous kaolins, calcium carbonate and talcs* optimize titanium dioxide in a formulation by spacing the TiO 2 particles for maximum efficiency across a range of pigment concentrations. Engineered products such as flash-calcined kaolins and precipitated calcium carbonates provide dry hiding and improved opacity in high PVC matt paints.
