Potassium Sorbate Food Grade (E202)

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.

Food Industry Applications

• Dairy products: Inhibits yeast and mold growth on yogurt surfaces, cottage cheese, sour cream, and cheese spreads preventing off-flavors and extending refrigerated shelf life by 1-2 weeks.

• ​Baked goods: Controls mold development in packaged tortillas, pitas, bread, pastries, and fillings maintaining freshness without affecting yeast fermentation or crumb structure.

• ​Beverages: Prevents refermentation and microbial clouding in fruit juices, flavored waters, wine, soft drinks, and carbonated beverages ensuring clarity and carbonation stability.

• ​Dry mixes and powders: Protects cake mixes, beverage powders, seasoning blends, and dry fruit products from moisture-induced mold during long-term storage.

• ​Processed meats: Reduces surface yeast and mold on sausages, deli meats, cured products, and dried meats improving safety and appearance in retail display cases.

Other Industry Applications

In the cosmetics industry, preserves water based formulations against microbial contamination; in the paints industry, prevents growth in water-based coatings; in the agriculture industry, treats seeds and extends post-harvest produce shelf life; in animal feed, prevents mycotoxin formation; in winemaking, stabilizes post-fermentation; in tobacco, controls microbial growth.
