Lactic acid is an organic acid that is produced naturally in the human body during intense physical activity when oxygen is in short supply. It is also found in many fermented foods, such as yogurt, sauerkraut, and sourdough bread. Lactic acid is a common food additive and cosmetic ingredient due to its acidic and moisturizing properties.
The Production Process of Lactic Acid
Lactic acid is produced through the fermentation of carbohydrates by lactic acid bacteria. The bacteria convert sugars such as glucose or lactose into lactic acid, which is then purified and used in various products. The fermentation process can be either natural or industrial.
Is Lactic Acid Vegan?

Lactic acid can be produced using various sources, including:
- Dairy-based bacteria: Lactic acid bacteria can be derived from dairy products such as milk, cheese, and yogurt.
- Plant-based bacteria: Lactic acid bacteria can also be obtained from plant sources such as fruits and vegetables.
- Synthetic production: Lactic acid can also be produced synthetically through chemical processes.
