Sodium Citrate is the sodium salt of citric acid, a white crystalline powder or granular crystals with a distinct sour-salty taste. Professionals also know it as "sour salt," sodium citrate, or the food additive E331.
If you're looking for high-quality sodium citrate for food production, medicine, or cosmetics, this product ideally meets BP (British Pharmacopoeia) standards. It's a safe, non-toxic component that is highly soluble in water and virtually insoluble in ethanol. This substance acts as an effective stabilizer, emulsifier, and acidity regulator, preventing fat oxidation and maintaining the structure of products.

Detailed description and advantages
Why should you buy sodium citrate from us? We offer Sodium Citrate, which undergoes strict quality control (a solution clarity and color test reveals a clear and colorless result).
Key benefits:
- A powerful emulsifier and melting salt: In the dairy industry, sodium citrate, food grade E331, is indispensable in the production of processed cheeses, preventing separation and ensuring a perfectly smooth texture. It also prevents milk from curdling during pasteurization (thermally stable).
- Acidity and flavor regulator: The additive softens the harsh taste of drinks, regulates the pH in desserts, marmalade, and jams, controlling the gelling process. This is the very substance that gives the flavor of sodas (especially citrus ones) a balanced flavor.
- Meat Product Stabilization: If you plan to buy sodium citrate in bulk or wholesale for a meat processing plant, know that it improves the water-holding capacity of ground meat, stabilizes the color of sausages, and reduces losses during heat treatment, acting as a safe replacement for phosphates.
- Antioxidant and Preservative: Protects fats and vitamins in products from oxidation, extending shelf life.
Many customers ask: what is sodium citrate? and what is citrate in the product composition? It is a safe component, even approved for use in baby food and formula.
Applications

- Food industry:
- Production of soft drinks and energy drinks.
- Confectionery (soufflés, marmalade, jelly).
- Dairy products (yogurts, condensed milk, processed cheese).
- Meat industry (wieners, frankfurters, cooked sausages).
- Medicine and pharmaceuticals:
- Sodium citrate in medicine is used as an anticoagulant (prevents clotting). (blood) in blood preservation.
- It is included in medications for cystitis, dehydration (rehydration), and hangover remedies.
- Cosmetology:
- Regulates pH in shampoos, shower gels, and creams.
- Used in bath bombs.
- Technical applications:
- Descaling boilers and radiators.
