2. Product Introduction

Potassium Bicarbonate (E501, CAS 298-14-6) is an inorganic potassium salt. It is produced through purification and crystallization processes to meet strict food safety standards. Food grade potassium bicarbonate is widely accepted as a safe food additive globally. It delivers excellent pH adjustment and leavening properties, and is commonly used as a low-sodium alternative to sodium-based additives in food formulations. Industrial grade potassium bicarbonate has limited applications and is briefly mentioned for reference.

3. Main Functions

3.1.Food Grade Core Functions 

Acidity Regulator & pH Stabilizer It neutralizes excess acid in food systems and maintains stable pH values during processing and storage. It prevents drastic pH fluctuation and protects the flavor, color and texture of finished food products.

Leavening Agent In baked goods, it reacts with acidic ingredients to release carbon dioxide. It creates uniform air pockets inside dough, helping bakery products rise and achieve light, fluffy texture. It serves as a preferred low-sodium leavening solution.

Potassium Nutrient Supplement It acts as a potassium source for functional foods and beverages, supporting potassium fortification in low-sodium formulations.

Processing Aid for Beverages Used in wine and carbonated drink production to adjust acidity, control fermentation environment and stabilize product flavor profile.

Anti-caking & Stabilizing Auxiliary It can help stabilize solid food mixes and reduce clumping in powder formulations.
