stability
1. Chemical properties: Lactic acid has hydroxyl and carbonyl groups, and when heated, it generates linear polyester like lactide. The initial esterification product is lactoyl lactic acid, and polylactic acid is formed with increasing concentration.
Most of them form linear polymers, and some of them form lactide.
Lactic acid is decomposed into acetaldehyde, carbon monoxide and water. A polymer of lactic acid that is decomposed into acetaldehyde and carbon monoxide in the presence of a catalyst.
However, acrylates and acetic acids are produced by the dry distillation of lactate diesters.
Lactic acid has the properties of general organic acids, and its salts are soluble in water. It can form esters with most alcohols. To inhibit the formation of lactic acid polymers, excess alcohol can be used. The hydroxyl group in lactic acid molecules can also react with organic acids, anhydrides, and acyl chloride to form esters. When heated with dilute sulfuric acid, it breaks down into formic acid and acetaldehyde.
2. Pure products are non-toxic. Its salts are non-toxic as long as they are not heavy metals. Oral LD503730mg/kg for rats.
3. It exists in tobacco leaves and smoke.
4. Naturally found in cooked beef, cocoa, and wheat breads.
5. In addition, it also exists in muscles, especially after intense muscle activity, the content of lactic acid increases, so the feeling of muscle swelling.

Lactic Acid Liquid, E270, CAS no.50-21-5, Chemical Formula C3H6O3, is a carboxylic acid manufacturing process through fermentation from corn starch. The lactic acid is a yellowish to colorless liquid, property having a mild acid odor and taste. Many bacterial species produce lactic acid, with Lactobacillus, Bifidobacterium, Streptococcus, Pediococcus and Leuconostoc. Lactic acid used as acid ingredient in sour dairy products, fermented fruits and vegetables and in sausages.
