Updating of the provisions on permitted additives in the various food categories, as well as on carrier substances for use in additives, enzymes, flavourings, vitamins, minerals and certain other substances with nutritional or physiological effects. On 6 May 2021, EFSA published an updated safety assessment for E 171. According to this, E 171 is no longer considered safe for use as a food additive. The EFSA safety assessment found that titanium dioxide is absorbed from the gastrointestinal tract to a very low extent, but takes a long time to be excreted from the body. In addition, titanium dioxide has the potential to accumulate in tissues. After evaluation of the available data, the suspicion of a mutagenic effect of titanium dioxide could not be invalidated. Based on this safety assessment, Switzerland decided that this additive should no longer be used in food.
