DL-tartaric acid racemic acid when in ratio. Important derivatives of tartaric acid include its salts, Cream of tartar potassium bitartrate , Rochelle salt potassium sodium tartrate, a mild laxative and tartar emetic antimony potassium tartrate. Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death.
The minimum recorded fatal dose for a human is about 12 grams. In spite of that, it is included in many foods, especially sour-tasting sweets. As a food additive, tartaric acid is used as an antioxidant with E number E, tartrates are other additives serving as antioxidants or emulsifiers. When cream of tartar is added to water, a suspension results which serves to clean copper coins very well.
This is due to the fact that the tartrate solution can dissolve the layer of copper II oxide present on the surface of the coin. Copper II -tartrate complex that is formed is easily soluble in water. Tartaric acid in wine. Tartaric acid may be most immediately recognizable to wine drinkers as the source of "wine diamonds," the small potassium bitartrate crystals that sometimes form spontaneously on the cork.
These "tartrates" are harmless, despite sometimes being mistaken for broken glass, and are prevented in many wines through cold stabilization. The tartrates that remain on the inside of aging barrels were at one time a major industrial source of potassium bitartrate.
However, tartaric acid plays an important role chemically, lowering the pH of fermenting "must" to a level where many undesirable spoilage bacteria cannot live, and acting as a preservative after fermentation. An emulsifier in baking processes, in table waters as an effervescent, in desserts as a leavening agent. Cosmetic The basic compound of many natural creams for the face and body thanks to its significant clarifying and antioxidant capacities. Pharmaceutical Used for the preparation of specific medicines antibiotics, cardiotonics etc.
Construction industry In the field of plasters and cements, it is used as a set retarder, while in the ceramic sector, tartaric acid is used as a fluidifier. Wine industry Tartaric acid improves the quality of wines by correcting their acidity, reducing the production of volatile acidity and making the colour brighter.
