Lactic acid has good thermal stability and is a sour agent, PH regulator and preservative. With low heavy metal content, it is an excellent complexing agent and buffer in the electroplating industry. It has a wide range of applications in the food, cosmetics and other industries. Lactic acid is a colorless, transparent, viscous liquid, slightly acidic, with hygroscopicity, and its aqueous solution shows acidic reaction. It can be mixed arbitrarily with water, ethanol or ether, and is insoluble in chloroform.

Application：
1. Lactic acid can be used in fruit wine, beverages, meat, food, pastry making, vegetables, pickling and canning processing, grain processing, fruit storage, etc., because it has the ability to adjust pH, extend shelf life, flavor, maintain food color, and improve Product quality and other effects;
2. In terms of seasonings, the special sourness of lactic acid can increase the deliciousness of food. Adding an appropriate amount of lactic acid to salads, soy sauce, vinegar and other seasonings can maintain the stability of the microorganisms in the product and make the taste more mild.
3. Lactic acid is an inherent ingredient in dairy products. It has the taste of dairy products and good antimicrobial effects. It has been widely used in foods such as blended yogurt, cheese, ice cream, etc., and has become a popular sour agent for dairy products.
Description：
Lactic acid (IUPAC scientific name: 2-hydroxypropionic acid) is a compound that plays a role in a variety of biochemical processes. It is a carboxylic acid with a molecular formula of C3H6O3. It is a carboxylic acid containing a hydroxyl group, so it is an alpha-hydroxy acid (AHA). In the aqueous solution, its carboxyl group releases a proton to produce the lactate ion CH3CHOHCOO. During fermentation, lactate dehydrogenase converts pyruvate to L-lactic acid. In general metabolism and exercise, lactic acid is constantly produced, but its concentration generally does not increase.
