What is Potassium Sorbate E202?

Potassium sorbate is a white crystalline powder or granular, soluble in water and ethanol. Its chemical formula is C6H7KO2 and E number is 202. Potassium sorbate is also known as e202 preservative and Sorbistat-K. Its antibacterial effect is within a wide pH range of 3.0 to 6.5. It works better in acidic conditions with a pH less than 5-6.

Sodium benzoate and potassium sorbate are often used synergistically in acidic foods to prevent a wider variety of microorganisms. Potassium sorbate is effective food preservative that can inhibit the growth of mold and yeast, thereby extending the shelf life of food.

What is Preservative 202 Made Of?

Preservative 202 is another name for potassium sorbate. It is the potassium salt of sorbic acid. Sorbic acid is a natural organic compound that can be derived from the berries of the mountain ash tree (Sorbus aucuparia). However, potassium sorbate used as a food preservative is typically produced synthetically.

The synthesis of potassium sorbate involves the reaction of sorbic acid with potassium hydroxide. This process results in the formation of potassium sorbate. Preservative 202 is commonly used in the food industry as a preservative to inhibit the growth of molds, yeasts, and bacteria, thus extending the shelf life of various food products.
