In recent years, instrumental techniques have gained prominence for their speed and precision. Ion chromatography, for instance, separates and quantifies ions based on their affinity to a resin within a chromatographic column. The sulfate ions are eluted and detected, typically by conductivity or UV detection after reaction with a reagent that enhances their detectability. The area under the peak in the chromatograph is proportional to the concentration of sulfate, which can then be translated to TiO2 content through appropriate calculations.

Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”.

Titanium dioxide powder, a white crystalline powder, is widely used in various industries due to its excellent physical and chemical properties. It has high refractive index, strong covering power, and good stability, making it an ideal material for paints, plastics, papermaking, and other fields. In recent years, with the rapid development of these industries, the demand for titanium dioxide powder has been growing steadily. Therefore, many countries have established titanium dioxide powder factories to meet this demand.
