Use
Aconitic acid has pleasant, winey, acid taste; almost odorless. Aconitic acid of the trans-configuration can be isolated during the processing of sugarcane by precipitating it as the calcium salt from cane syrup or molasses. The concentration in molasses ranges from 1.8 to 2.5%. Aconitic acid may be synthesized from citric acid by dehydration with sulfuric acid or by catalytic dehydration. The cis-configuration is somewhat unstable and is readily rearranged to the trans form by heating. Trans-aconitic acid is decarboxylated to itaconic acid by heating to 180F. The cis form occurs in plant and animal tissues as a metabolic intermediate in the Krebs cycle during the isomerization of citric acid to isocitric acid by the action of enzyme aconitase.
