Introduction
Tartaric acid i.e., 2, 3 - dihydroxybenzoic acid, a carboxylic acid, present in many plants, such as grapes and tamarind, it is one of the main organic acids in wine. As antioxidants in foods, it can make the food have acidity. The largest use of tartaric acid is the beverage additives. Also tartaric acid is the raw material in pharmaceutical industry. In the mirror industry, tartaric acid is an important additive and a reducing agent, can control the rate of formation of silver mirror, to obtain a very uniform coating.
Tartaric acid molecule has two asymmetric carbon atoms, so there are three kinds of optical isomers, i.e. D-tartaric acid, L-tartaric acid, meso-tartaric acid. The same amount of L-tartaric acid and D-tartaric acid was racemic tartaric acid or DL-tartaric acid. Natural tartaric acid is D-tartaric acid. The largest industrial production is racemic tartaric acid.

Applications
The largest use of tartaric acid is the beverage additives. The second is the raw material in pharmaceutical industry. In contemporary organic synthesis tartaric acid is very important chiral ligands and Chiron, it can be used to prepare much famous chiral catalyst, and the synthesis of a chiral complex natural product molecules. Tartaric acid is an antioxidant that has been applied in the food industry. Biochemical tests can be used as an oxygen scavenger.

Growing trend
Tartaric acid was first found in 1769 by the Swedish chemist William Karl. Up to now, it has a history of nearly 250years. But it was not until recent years, tartaric acid production has been attention, and applied in many industries. Although in today's acid used in the food industry for at least 20 kinds, but just three calculate accounts for about 80% of the food acidulant overall consumption. Tartaric acid is one of them. Tartaric acid production started late, backward production technology, and tartaric acid demand is expected to increase rate of 15% per year, there is an urgent need to develop new separation process of tartaric acid, tartaric acid to expand production scale, improve product quality to meet the domestic and international markets requirements. L (+) - tartaric acid market prospects are very good. It will become the citric acid, malic acid, lactic acid after another national production and daily life play a huge role in the biosynthesis of organic acids.

Shanhong Chemical Co, Ltd was founded in 2007. We specialize in the production of fine chemicals and food additives which can be widely used in food, medical, chemical and construction industries. Our major products include DL-tartaric acid, L-(+) - tartaric acid, D (-) - tartaric acid, potassium sodium tartrate and many other tartaric salts. With years of development, we have been one of the major suppliers of tartaric acid in China. Our company is with complete production equipments, advanced techniques and well-trained staff, which guarantee the high quality of our products.
