Metatartaric acid is a food additive. Chemically, it is a polymeric lactone of variable composition and different molecular weights obtained through a dehydration reaction by heating tartaric acid. [2]
As a food additive, it has the E number E353 and is classified as an acidity regulator. [1] It is added to wine to prevent the precipitation of potassium hydrogen tartrate and calcium tartrate. [3]
