Description and Uses

Sodium lactate is the sodium salt of lactic acid that has a mild saline taste. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC₃H₅O₃
As early as 1836, sodium lactate was recognized as a salt of a weak acid rather than being a base, and it was then known that the lactate had to be metabolized in the liver before the sodium could have any titrating activity.

The sodium salt of lactic acid (L113490). It acts as a preservative, acidity regulator, and bulking agent.
