Sodium Lactate (E325)

Brief Overview Sodium lactate is the sodium salt of lactic acid. It is produced by fermenting sugar sucrose from corn or beets and then neutralizing it with lactic acid. It is widely used in the food industry as a preservative, acidity regulator, and thickener. It is also used for the regulation of acid-base imbalance in our bodies. Manufacturing Process Sugar is fermented using appropriate bacillus to produce lactic acid in the presence of an anti-acid like calcium carbonate, which will finally result in calcium lactate. The bacteria is then killed, and the solution is filtered. This solution is neutralised with a suitable acid like sodium carbonate. On further processing, sodium lactate is produced.
