Application of Sodium Citrate Dihydrate
Core Identity & Primary Application
Sodium Citrate Dihydrate is a hydrated citrate salt with stable buffering performance and controlled solubility, making it suitable where consistent pH regulation and processing stability are required.
Application-Specific Advantages
- Food & Beverage Processing
◼ Key Role: Acts as a buffering and acidity-regulating agent to maintain target pH in foods and drinks.
◼ Why Choose: The dihydrate form offers steadier dissolution and handling compared with anhydrous citrate in standard aqueous systems. - Dairy & Processed Foods
◼ Key Role: Functions as an emulsifying salt to stabilize texture and prevent protein separation.
◼ Why Choose: Provides reliable emulsification performance with less sensitivity to minor moisture variations during processing. - Pharmaceutical Formulations
◼ Key Role: Used as a pH adjuster and buffering agent in oral and liquid preparations.
◼ Why Choose: Hydrated crystal form supports predictable solubility and formulation consistency. - Industrial & Laboratory Use
◼ Key Role: Serves as a general buffering reagent in analytical and preparation processes.
◼ Why Choose: Easy handling and stable hydration state reduce variability in routine applications.
