 U.S. FDA/CFSAN: Agency Response Letter: GRAS Notice No. GRN 000187
L (+) tartaric acid (alternative method) is produced by the conversion of maleic anhydride to tartaric acid through the enzymatic action of the enzyme cis-epoxisuccinate hydrolase, contained in immobilized R.
Because the notifiers' L (+) tartaric acid will substitute for the uses of tartaric acid prepared as described in 21 CFR 184.1099, total daily intake of tartaric acid is not expected to change from the current level.
L (+) tartaric acid (alternative method) is chemically identical to tartaric acid affirmed as GRAS in 21 CFR 184.1099, and meets the specifications for tartaric acid in the Food Chemical Codex (FCC), 5th ed., 2003.

 Process for producing tartaric acid from a raw material containing potassium hydrogentartrate - Patent 6534678
Tartaric acid has the empirical formula H.sub.6 C.sub.4 O.sub.6, potassium hydrogentartrate is KH.sub.5 C.sub.4 O.sub.6 and dipotassium tartrate is K.sub.2 H.sub.4 C.sub.4 O.sub.4.
If a highly purified tartaric acid is desired, the solution of line 28 is also passed through an anion exchanger 30, which in the initial state is loaded with tartaric acid.
For removing the potassium ions the decolorized solution is passed over a strongly acid cation exchanger 26 and there is obtained a purified aqueous tartaric acid solution, which is suited for concentration, evaporation and crystallization in a manner known per se.

Getting a better handle on how grapes make tartaric acid will help vintners make a crisper sauvignon blanc or avoid producing a soapy Semillon, said Doug Cook, a plant biologist at UC Davis whose work on the grape genome provided the foundation for the discovery.
Their investigation revealed that wild grapes lacking the gene also lack tartaric acid and contain more vitamin C. Blocking the conversion of vitamin C to tartaric acid could boost the vitamin C content in the grape.
