Biochem/physiol Actions

Lactic acid is produced by lactic acid bacteria (LAB) during carbohydrate fermentation. Different microorganism synthesize different forms of lactic acid such as L(+), D(-) or DL (racemic mixture). It is preferred in food processing and preservation due to its antimicrobial property. Lactic acid is useful as a flavoring and acidifying agent.

General description

Lactic acid is an α hydroxyl carboxylic acid produced from pyruvate by the enzyme lactate dehydrogenase (LDH). Lactate is one of the main components of Ringer′s lactate or lactated Ringer′s solution.
