What is tartaric acid?
Tartaric acid is a dihydroxy succinic acid.
It is found in plants such as grapes and tamarind, and is also one of the main organic acids in wine.
Pasteur was the first to discover that tartaric acid with different structures has different optical rotation properties, such as a pair of gloves divided left and right, also known as chirality.
Pasteur's discovery is a milestone in the history of chemistry.
Professional Interpretation: There are three chemical isomers of tartaric acid, namely L (+) - tartaric acid (dextral), D (-) - tartaric acid (levo) and ESO - tartaric acid (racemic). The tartaric acid obtained by chemical synthesis is usually DL-tartaric acid (racemic) with 50% dextral and 50% levo-tartaric acid respectively. L(+) -tartaric acid is a natural configuration, also known as d-tartaric acid, which widely exists in many plants, such as grapes and tamarind fruits. D (-) - tartaric acid is also known as L - tartaric acid, which is found in the fruits and leaves of the goat's shoe nail. L(+)-tartaric acid and D(-)-tartaric acid can be obtained by conversion of Epoxysuccinic acid with different enzymes, or by chemical resolution of DL-tartaric acid.

Just like Magic Master changing different incarnations to serve us
Create infinite splendor for our life
Professional Interpretation: The starting material of biosynthesis of L(+) -tartaric acid is the same as DL-malic acid. Therefore, biosynthesis of L(+) -tartaric acid has been purchased and used by most international large food enterprises as well as DL-malic acid, and has been widely used in the following fields.
CAN BE USED IN BELOW APPLICATION:
1)Wine Acidifier
L(+)-tartaric acid is known as the gem in red wine and the most important acid regulator in wine. In addition, L(+)-tartaric acid is the only organic acid that is not absorbed by human body, so it is used in high-grade beverages.
2)Pharmaceutical Separator
L(+)-tartaric acid is the most important resolution agent for chemical resolution in the synthesis of chiral compounds; it is also a salt-forming agent for some drugs.
3)Food emulsifier
L(+) - tartaric acid is the main material of food emulsifier DATEM. Emulsifier DATEM is a good food emulsifier and dispersant because of its strong emulsifying, dispersing and anti-aging effects. It can effectively enhance the elasticity, toughness and air-holding of dough, prevent the aging of dough, increase the volume of bread and steamed bread, and improve the flour structure. In addition, DATEM is also widely used in butter, vegetable fat powder, ice cream and other foods.
4)Gesso retarder
L(+) -tartaric acid is the most important retarder in building material gypsum and the best retarder in gypsum so far. In addition, it can also be used as cement retarder, especially as self-leveling cement retarder.
5)Cosmetic raw materials
L(+)-tartaric acid is also used as a diet tea and cosmetic ingredient.
6)Metal polishing agent
L(+)-tartaric acid is a powerful complexing agent of metal ions, and is therefore used as a cleaning agent and polishing agent for metal surfaces.
