Potassium Sorbate (PSG) – a (almost) neutral preservative

Supplier for Potassium Sorbate (PSG)/E 202

Potassium Sorbate (PSG) / E 202 is the potassium salt of sorbic acid, and is known for its preserving properties against yeasts and molds. It inhibits their growth, thereby enhancing the shelf life of cosmetics, food, and pharmaceuticals. It’s most effective in acidic products with a pH < 5.5, such as juices, jams, fermented foods, and baked goods. It's worth mentioning that the approval for using Potassium Sorbate (PSG) comes with certain restrictions and regulations regarding permissible maximum levels. Thus, its application is excluded or limited, especially in fresh, unprocessed foods like fruits, vegetables, meat, and fish.
