Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes but also in tamarinds, bananas, avocados, and citrus. [1] Its salt, potassium bitartrate, commonly known as cream of tartar, develops naturally in the process of fermentation.
The reason some dogs develop kidney failure following ingestion of grapes and raisins is not known. [3] Types of grapes involved include both seedless and seeded, store-bought and homegrown, and grape pressings from wineries. [4] A mycotoxin is suspected to be involved, but none has been found in grapes or raisins ingested by affected dogs. [5]
A tartrate is a salt or ester of the organic compound tartaric acid, a dicarboxylic acid.The formula of the tartrate dianion is O − OC-CH(OH)-CH(OH)-COO − or C 4 H 4 O 6 2−. [1]The main forms of tartrates used commercially are pure crystalline tartaric acid used as an acidulant in non-alcoholic drinks and foods, cream of tartar used in baking, and Rochelle salt, commonly used in ...
Tartaric acid [9] is the most prominent acid in wine with the majority of the concentration present as potassium bitartrate. During fermentation, these tartrates bind with the lees, pulp debris and precipitated tannins and pigments. While there is some variation according to grape variety and climate, usually about half of the deposits are ...
It is the potassium salt of tartaric acid. It is often confused with potassium bitartrate, also known as cream of tartar. As a food additive, it shares the E number E336 with potassium bitartrate. [1] Potassium bitartrate, also referred to as potassium acid tartrate or cream of tartar, [2] is the potassium acid salt of l-( + )-tartaric acid. It ...
Malic and tartaric acid are the primary acids in wine grapes. The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria.
From racemic acid found in grapes; from Latin racemus, meaning a bunch of grapes. This acid, when naturally produced in grapes, is only the right-handed version of the molecule, better known as tartaric acid. In many Germanic languages racemic acid is called “grape acid” e.g. German traubensäure and Swedish druvsyra.
Typical acidulants are acetic acid (e.g. in pickles) and citric acid. Many beverages, such as colas, contain phosphoric acid. Sour candies often are formulated with malic acid. [2] Other acidulants used in food production include: fumaric acid, tartaric acid, lactic acid and gluconic acid. [1]
