2. What foods contain titanium dioxide?

Not everyone agrees, though. The European Commission banned titanium dioxide as a food additive in the European Union in 2022.

Thanks to its rheological and optical properties, Lithopone offers both technical and economic advantages wherever organic and inorganic binder systems require a relatively high pigmentation for specific applications.

In 1970, Japanese scholars studied the phase diagram of iron oxide microcrystalline formation, which laid a theoretical foundation for the preparation method of iron oxide yellow crystal seed. According to the research results, iron yellow crystal seeds can be formed under acidic or alkaline conditions. Because iron yellow is a crystal structure, in order to crystallize into pigment particles, it must first form crystal nucleus and become crystal seed, and then the crystal nucleus grows into iron yellow. Otherwise, only thin and dim color paste can be obtained, which does not have pigment properties. Acid process can be divided into iron sheet process and drop addition process.
