The organic acids are mainly malic and tartaric acids. Three primary acids are found in wine grapes&colon; tartaric, malic and citric acids. Acids can be added in manufacturing such as acetic, malic, tartaric, and citric. Effervescent antacids may also contain aspirin, sodium carbonate, or tartaric acid. Inactive ingredients include menthol, tartaric acid, and propylene glycol. It is processed from the potassium acid salt of tartaric acid (a carboxylic acid). DATEM is derived from tartaric acid and monoglycerides and diglycerides. It is the potassium salt of tartaric acid. The -(+)-tartaric acid isomer of tartaric acid is industrially produced in the largest amounts. The principal component of this deposit is potassium bitartrate, a potassium salt of tartaric acid. A variety of acidifiers can be used, including potassium bitartrate, tartaric acid, and disodium phosphate. Bitartrate is an anion which is the conjugate base of tartaric acid. The latter can be synthesized by adding aqueous ammonia to an excess of tartaric acid. As an acidulant in baking powders, it avoids the undesirable hygroscopic properties of tartaric acid. Another solution is to introduce Metatartaric acid, a tartaric acid polymer, into the wine.
