Sodium Citrate
ZIO
Sodium Citrate is an organic acid salt derived from citric acid and sodium, typically existing as white crystalline granules or a fine powder. It is odorless, with a subtle salty-sour taste, and boasts high solubility in water (while being insoluble in ethanol). This solubility makes it easy to blend into liquid and solid formulations, a key trait for diverse industrial applications.
As a versatile raw material, it is widely used across food & beverages, pharmaceuticals, detergent production, and water treatment sectors. Its ability to perform multiple functions—from pH control to stabilization—makes it a staple in both consumer and industrial products.
The primary components of Sodium Citrate come from natural citric acid (often produced via fermentation of starch-based materials) and high-purity sodium. This natural origin ensures the ingredient is safe for human consumption and aligns with consumer demand for "cleaner" additives.
All ingredients meet strict international standards for food additives and pharmaceutical raw materials. This compliance eliminates harmful impurities, guaranteeing consistent quality across batches and suitability for sensitive applications (e.g., infant food, injectable medications).
Property | Value |
Chemical Name | Sodium Citrate |
Molecular Formula | C₆H₅Na₃O₇·2H₂O |
CAS No. | 6132-04-3 (commonly as dihydrate) |
Appearance | White crystalline granules or powder |
Taste | Slightly salty and sour, odorless |
Solubility | Easily soluble in water, insoluble in ethanol |
pH Buffer Range | 3.0 – 6.2 |
Functions | Buffer, emulsifier, anticoagulant, preservative |
Derived from natural sources, Sodium Citrate undergoes rigorous quality testing to ensure it is non-toxic. Global health authorities (such as FAO/WHO) impose no restrictions on its daily intake, making it a trusted choice for food, beverages, and pharmaceuticals.
In food & beverages: It acts as a pH regulator to balance acidity, a buffering agent to prevent pH fluctuations, an emulsifier to improve texture (e.g., in cheese), and a preservative to extend shelf life. It enhances flavor in juices and stabilizes ingredients in dairy products.
In pharmaceuticals: It functions as an anticoagulant for blood transfusion and testing, and an acid-base balance regulator for treating metabolic acidosis.
In industry: It serves as a chelating agent in water treatment (binding metal ions to improve water quality) and a boosting ingredient in detergents (enhancing cleaning power).
Its high water solubility allows for quick dissolution and uniform mixing, reducing formulation time and avoiding clumping in products like carbonated drinks or powdered pharmaceuticals.
Sodium Citrate maintains consistent quality under normal thermal and storage conditions. It does not degrade or lose functionality, ensuring reliable results in long-term production and product storage.
Store Sodium Citrate in a cool, dry area with sealed packaging. This prevents moisture absorption (which may cause clumping) and avoids direct sunlight—though light exposure does not affect its chemical properties.
While safe for most people, individuals with hypertension or kidney issues should monitor sodium intake (as Sodium Citrate contains sodium). Consult healthcare professionals before regular use of high-concentration products.
When used in food or pharmaceuticals, adhere to industry-specific regulations (e.g., food additive limits, pharmaceutical grade requirements) to ensure compliance and avoid improper use.
Yes. It is derived from natural citric acid, meets global safety standards, and has no daily intake limits. It is commonly found in dairy products, juices, and baked goods.
As an emulsifying salt, it improves cheese texture by preventing ingredient separation and enhances smoothness. It also regulates pH to maintain freshness and extend shelf life.
Absolutely. It is a key anticoagulant for blood storage and testing, and an acid-base regulator for metabolic acidosis treatment. It must meet pharmaceutical-grade standards.
Its strong chelating properties bind metal ions (e.g., calcium, magnesium) in water, reducing mineral deposits and improving water quality—making it an effective chelating agent.
