Application of Sodium Citrate Anhydrous
Core Identity & Primary Application
Sodium Citrate Anhydrous is a water-free citrate salt used in food formulations where precise pH control and minimal moisture addition are required.
Application-Specific Advantages
- Beverages & Syrups
◼ Key Role: Regulates acidity and buffering capacity in soft drinks, concentrates, and flavored syrups.
◼ Why Choose: Anhydrous form allows rapid dissolution without diluting formulations. - Dry Food & Powdered Mixes
◼ Key Role: Adjusts pH and improves stability in instant drinks, seasonings, and powdered foods.
◼ Why Choose: Low moisture content supports better flowability and longer shelf life. - Dairy & Processed Cheese Products
◼ Key Role: Acts as an emulsifying salt to stabilize proteins and control texture.
◼ Why Choose: Selected for consistent performance where moisture balance is critical. - Bakery & Confectionery
◼ Key Role: Provides buffering to maintain flavor stability and processing consistency.
◼ Why Choose: Suitable for formulations that require controlled acidity without additional water input.
Main Types of Sodium Citrate Anhydrous
One main type is Anhydrous Sodium Citrate, with the chemical formula C₆H₅Na₃O₇. It has no water of crystallization, features low hygroscopicity, and boasts high thermal stability. This type is well-suited for high-temperature processing scenarios such as the production of baked goods and canned foods, as well as for use in industrial formulations.
Another key type is Sodium Citrate Dihydrate, with the chemical formula C₆H₅Na₃O₇·2H₂O. It contains 2 molecules of water, has higher solubility, and exhibits moderate hygroscopicity. It is commonly applied in liquid products like beverages and oral solutions, as well as in room-temperature food processing.
Both Anhydrous Sodium Citrate and Sodium Citrate Dihydrate function as acidity regulators, chelating agents, and stabilizers in the food, pharmaceutical, and chemical industries. The choice between them depends on specific processing conditions and storage requirements.
