Potassium sorbate CAS#24634-61-5 Products Description
Potassium sorbate is a white, crystalline powder that serves as the potassium salt of sorbic acid. Originally discovered in the 1850s in the Mountain Ash Tree, it is now manufactured synthetically. Widely used as a food preservative, potassium sorbate is biodegradable and has a chemical structure similar to that of naturally occurring fatty acids. Its primary function is to prevent the growth of molds and yeasts, thereby helping to preserve food products.

Potassium sorbate CAS#24634-61-5 Product Application
Potassium sorbate dissociates in water to release sorbate ions, which provide effective antimicrobial activity against yeasts, molds, and certain bacteria. It is widely used as a food preservative at typical concentrations of approximately 250–1,000 ppm, depending on the product formulation and applicable regulations.
Its applications span a broad range of food products, including cheese, dips, yogurt, sour cream, bread, cakes, pies, fillings, baking mixes, doughs, icings, fudge, toppings, beverages, margarine, salads, fermented and pickled vegetables, olives, fruit-based products, dressings, smoked and salted fish, confectionery, and mayonnaise.
With its broad applicability and ability to help control microbial spoilage, potassium sorbate is an effective and widely utilized preservative in the food industry.
