Sorbic acid is a natural organic compound widely used as a preservative in the food, beverage, cosmetics, and pharmaceutical industries. It is highly effective at inhibiting the growth of mold, yeast, fungi, and many common bacteria, which helps extend the shelf life of products and maintain their safety and quality.

It is known for its stability, low volatility, and good compatibility with various formulations. Sorbic acid works by disrupting the metabolic processes of microorganisms without significantly affecting the taste, odor, or appearance of the final product when used at recommended levels.
