The Panel on Food Additives and Flavourings (FAF) provided a scientific opinion re-evaluating the safety of metatartaric acid (E 353) when used as a food additive. Metatartaric acid (E 353) had been previously evaluated by the Scientific Committee on Food (SCF) and Joint FAO/WHO Expert Committee on Food Additives (JECFA). Based on the presumption that metatartaric acid is fully hydrolysed pre-systemically to l(+)-tartaric acid, the Panel concluded that metatartaric acid (E 353) should be included in the group acceptable daily intake (ADI) of 240 mg/kg body weight (bw) per day, expressed as tartaric acid, for l(+)-tartaric acid-tartrates (E 334–337, 354) which was established by the EFSA FAF Panel in 2020. Exposure estimates were calculated for metatartaric acid (E 353) using a maximum level and refined exposure assessment scenario. The Panel also concluded that there is no safety concern for the use of metatartaric acid (E 353) at the reported use and use level. The Panel made a number of recommendations.
