Lactic Acid
What is Lactic Acid?
Lactic acid is a naturally occurring organic acid produced through the fermentation of carbohydrates by lactic acid bacteria. It is commonly found in fermented foods and milk products.
In the food industry, lactic acid is used as a preservative, acidity regulator, and flavor enhancer. It helps to prolong shelf life by inhibiting the growth of certain bacteria and contributes to the tangy taste of fermented products. Health-wise, it is generally considered safe for consumption, although individual sensitivities might occur.
While lactic acid can be produced naturally, it can also be synthesized. On labels, it's good to note whether the product claims any specific benefits from natural fermentation processes.
Commonly found in: dairy products, pickles, sauces, crackers, candy
Benefits
- Lactic acid can extend the shelf life of products by acting as a natural preservative.
Lactic acid is generally recognized as safe (GRAS) for use in food by the FDA.
Research supports its use in food without significant health concerns, although individual sensitivities may occur.
Lactic acid can be vegan if sourced from plant-based fermentation, but it is sometimes derived from dairy. Vegan labeling clarifies the source.
