Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.
To overcome this challenge, manufacturers use advanced technology and processes to monitor and control the buff percentage of their products. This may involve the use of sophisticated equipment to measure the coating thickness of titanium dioxide particles, as well as automated systems to adjust the level of coating as needed. By carefully controlling the buff percentage, manufacturers can ensure that their products meet the specifications of their customers and maintain a high level of quality and performance.
Check food product labels and avoid those with titanium dioxide. Food companies must list titanium dioxide on packaged food ingredient labels. In some instances, it may simply be listed as “artificial color” or “color added.”
For that reason, the Center for Science in the Public Interest has graded titanium dioxide as a food additive that consumers should seek to “avoid.” Scientists at the nonprofit nutrition and food safety watchdog group today published a new entry for titanium dioxide in its Chemical Cuisine database of food additives.
Spectrophotometric methods are also employed, where the absorbance of light by a sample is measured after a color-forming reaction specific to sulfate. By comparing the absorbance values to a calibration curve prepared with standards of known TiO2 content, the concentration of sulfate can be accurately determined.

It's also worth noting that even prior to the EU decision, France had already outlawed titanium dioxide in food back in January 2020.
