Potassium Sorbate Potassium sorbate is the potassium salt of sorbic acid produced through chemical neutralization, used as a broad-spectrum antimicrobial preservative (E202) that inhibits mold, yeast, and aerobic bacteria growth by disrupting cell membrane function while remaining inactive against beneficial lactic acid bacteria. In the food industry, it provides effective preservation across a wide pH range (2.5-6.5), clean flavor, and heat stability ideal for beverages, dairy, bakery, and dried fruits.
