Application of Sodium Citrate
Sodium Citrate
Chemical Formula: C6H5Na3O7Molecular Weight: 258.069
CAS Number: 68-04-2
EINECS Number: 200-675-3
Sodium citrate appears as white to colorless crystals. Odorless, with a refreshing salty and spicy taste.
Application:
Sodium citrate is used as a flavoring agent and stabilizer in the food and beverage industry;Used as an anticoagulant, expectorant, and diuretic in the pharmaceutical industry;
In the detergent industry, it can replace sodium tripolyphosphate as a non-toxic detergent additive;
It is an excellent chelating agent/complexing agent in chemistry, and its industrial application to sodium citrate utilizes this characteristic.
It is also used for brewing, injection, photography pharmaceuticals, and electroplating.
Food Applications
Sodium citrate used in refreshing beverages can alleviate acidity and improve taste.Adding sodium citrate to brewing can promote saccharification.
Sodium citrate can be used as an emulsifier and stabilizer in ice cream and ice cream manufacturing.
Sodium citrate can also be used as a preservative for dairy products, a thickening agent for processed cheese and fish products, and a sweetener for food.
Sodium citrate is used as a food additive with the highest demand, mainly as a flavoring agent, buffering agent, emulsifier, expansion agent, stabilizer, and preservative.
In addition, sodium citrate is used in combination with Citric Acid as a gelling agent, nutritional supplement, and flavoring agent for various jams, jellies, juices, beverages, cold drinks, dairy products, and pastries.
Medical Applications
In the field of medicine, sodium citrate is also widely used. By utilizing the property of citrate ions forming soluble complexes with calcium ions, it can be used as an anticoagulant and transfusion agent for the preservation and processing of blood products.Sodium citrate is used as a preservative to preserve medicines such as syrup.
Sodium citrate injection, like potassium salt, is used to correct the acidity of blood, body fluids, and urine, as a diuretic, expectorant, etc.
Sodium citrate can be used in combination with other reagents to extract and purify animal liver ribonucleic acid.
Chemical applications
Sodium citrate has good water solubility, excellent chelating ability for metal ions such as Ca2+and Mg2+in water, biodegradability, strong dispersibility, and anti redeposition ability. It is used to produce phosphate free laundry detergent, especially phosphate free liquid detergent. Adding a certain amount of sodium citrate to detergent can significantly increase its cleaning ability.
Some specialized cleaning agents containing sodium citrate are non corrosive to certain metal instruments, making them suitable for cleaning valuable precision instruments; After cleaning utensils with specialized detergents containing sodium citrate, the metal surface becomes as shiny as new, and the waste liquid after cleaning can be regenerated and reused after treatment, reducing the cost of washing.
Sodium citrate has excellent chelating properties and is therefore widely used in the electroplating industry.
In the construction industry, sodium citrate can be added as a retarder to concrete to improve the tensile, compressive, and frost resistance of cement products.
In terms of environmental protection, sodium citrate can be used to remove sulfides from industrial exhaust gases.
In the ceramic industry, sodium citrate can be used as a grinding aid additive.
In addition, sodium citrate has new uses in the brewing and photography industries, further expanding its application areas.
