The starting material of biosynthesis of L(+) -tartaric acid is the same as DL-malic acid. 

Therefore, biosynthesis of L(+) -tartaric acid has been used by most international large food companies as well as DL-malic acid, and has been widely used in many fields.

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.
