DL-Tartaric Acid
Tartaric acid (tartaric acid) was first extracted from tartarite, a by-product of wine. Due to the presence of two asymmetric carbon atoms in the molecular structure, left-handed (l-tartaric acid) and dextral (d-tartaric acid), internal racemic (meso-tartaric acid) and racemic (dl-tartaric acid) exist. Tartaric acid is highly soluble in water, and is soluble in , ethanol, glycerol and other polar solvents, slightly soluble in ether, partially soluble in, and is widely used in food, pharmaceutical, light industry, chemical industry and other industries. In the food industry, tartric acid is an excellent sour agent, and its sour taste is 1.2-1.3 times that of citric acid, with a unique flavor. According to the health standards of food additives used in China, it mainly with citric acid, malic acid, can be used in drinks, canned, jam, candy, etc., because the tartaric acid as fermentation powder raw material with other edible organic acid characteristics, so some occasions can also be used as chelating agent, antioxidant synergist, enhancing agent, firming leavening agent. In the pharmaceutical industry, tartaric acid can be used as a pharmaceutical intermediate and an efficient resolution agent. Can be used in the chemical industry to produce tartrate and tartrate, which can be used as a cleaner and polishing agent for metal surfaces. In the textile industry, tartric acid and tannin can be used as acid dyes. In addition, tartaric acid in leather, cement, photographic development and other industries.
