DL-Tartaric acid
DL-Tartaric acid
DL tartaric acid, also known as 2,3-dihydroxysuccinic acid, has a molecular formula of C4H6O6NH2O (crystalline: n=1, anhydrous: n=0). It appears as colorless crystals or white crystalline powder, odorless, and has a sour taste. It is a mixture of equal amounts of right-handed and left-handed tartaric acid, often containing one or two crystalline waters, which lose water when heated to 100 ° C. Stable in air, with a density of 1.697, its solubility in water is 20.6 (20 ° C), its solubility in ether is about 1%, and its solubility in ethanol is 5.01 (25 ° C). It is widely used in the food industry, such as as as a beer foaming agent, food acidifier, flavoring agent, for refreshing beverages, candies, juices, sauces, cold dishes, fermentation powders, etc. Its acidity is 1.3 times that of citric acid, and it is particularly suitable as an acidifier for grape juice.
