Malic acid, also known as 2 - hydroxy succinic acid, has two stereoisomers due to the presence of an asymmetric carbon atom in the molecule. There are three forms in nature, namely D malic acid, L malic acid and its mixture DL malic acid. White crystalline or crystalline powder with strong moisture absorption, easily soluble in water and ethanol. Have a special pleasant sour taste. Malic acid is mainly used in food and medicine industry.
Description
Malic acid is commonly used in the preparation of medicines, mordants and tanning agents, and is also commonly used as a reagent for the resolution of racemic basic compounds. It is also a sour agent in food additives, sourness is better than malic acid, lactic acid and so on. Several of its salts have important applications. For example, the Fehling reagent is formulated with potassium sodium tartrate in the laboratory to identify aldehyde functional groups in the structure of organic molecules. Its potassium and sodium salt is also called Rochelle's salt. Its crystals are polarized under pressure to produce a potential difference (piezoelectric effect) on both ends of the surface, which can be made into piezoelectric elements for radio and cable broadcasting. The receiver and pickup. Medically, potassium antimony tartrate (commonly known as tartrate) is used to treat schistosomiasis.
Application
1.In food industry: it can be used in the processing and concoction of beverage, liqueur, fruit juice and the manufacture of candy and jam etc. It also has effects of bacteria inhibition and antisepsis and can remove tartrate during wine brewing.
2.In tobacco industry: malic acid derivative (such as esters) can improve the aroma of tobacco.
3.In pharmaceutical industry: the troches and syrup compounded with malic acid have fruit taste and can facilitate their absorption and diffusion in the body.
4.Daily chemical industry: as a good complexing agent, it can be used for toothpaste formula, spice synthesis formulas and so on. It also can be used as a deodorant and detergent ingredients. As a food additive, malic acid is an essential food ingredient in our food supply.As a leading food additives and food ingredients supplier in China, we can provide you with high quality malic .
