Sodium Citrate 25kg
Sodium Citrate is the sodium salt of citric acid, available as a white, crystalline powder or granules. It functions primarily as a buffering agent, acidity regulator, and sequestrant in food, pharmaceutical, and industrial applications. It helps maintain pH stability, enhances flavor, and prevents metal ion-induced spoilage. The 25kg packaging is typical for bulk industrial or food processing use.
Uses
Primary UsesÂ
- Food & Beverage Industry
- Acts as a buffering agent to maintain stable pH in beverages, dairy products, and processed foods.
- Functions as a sequestrant to bind metal ions, preventing oxidation and spoilage.
- Used as a flavoring agent to impart a mild tartness in soft drinks, jams, and confections.
- Serves as an emulsifier in processed cheese and dairy products for smooth texture.
- Pharmaceuticals
- Used as an alkalizing agent in oral and injectable formulations.
- Included in effervescent tablets and powders for controlled acidity.
- Acts as an anticoagulant in blood collection tubes by chelating calcium ions.
- Cosmetics and Personal Care
- Functions as a pH adjuster and chelating agent in skincare and haircare products.
Secondary Uses
- Industrial Applications
- Used in detergents and cleaning agents as a water softener and pH buffer.
- Employed in photographic processing as a buffering agent.
- Laboratory & Analytical
Utilized as a buffering agent in biochemical assays and molecular biology protocols.
