CALCIUM TARTRATE химические свойства, назначение, производство
Описание
Calcium tartrate is a by product of the wine industry, prepared from wine fermentation dregs. It is the calcium salt of tartaric acid, an acid most commonly found in ripe grapes. Its solubility decreases with colder temperature, which results in the forming of whitish (in red wine often reddish) crystalline clusters as it precipitates. It finds use as a food preservative and acidity regulator. Like tartaric acid, calcium tartrate has two asymmetric carbons, hence it has two chiral isomers and a non-chiral isomer (meso-form). Most calcium tartrate of biological origin is the chiral levorotatory (–) isomer.Химические свойства
