0-30 mg/kg bw
Comments:
As metatartaric acid undergoes enzymatic hydrolysis to tartaric acid prior to systemic absorption, the biochemical
and toxicological data on tartaric acid considered at previous meetings are relevant to the safety assessment of
metatartaric acid. Previously evaluated and new studies suggest no change to the group ADI previously established
for L(+)-tartaric acid and its sodium, potassium and potassium–sodium salts, expressed as L(+)-tartaric acid. The Committee concluded that metatartaric acid (when used in winemaking) should be included in the group ADI of 0–30 mg/kg bw for L(+)-tartaric acid and its sodium, potassium, potassium–sodium salts,
expressed as L(+)-tartaric acid.
