What Is Sodium Citrate?
Sodium citrate, also known as sodium citrate, is a white crystalline particle or powder at room temperature, odorless, with a cool and salty taste, and stable in the air. Sodium citrate is used as flavoring agent and stabilizer in food and beverage industy.
Solubility: Sodium citrate is soluble in water and glycerol, and slightly soluble in ethanol.
Biodegradability: After sodium citrate is diluted with a large amount of water in nature, part of it turns into citric acid, and the two coexist in the same system. Citric acid is easily biodegraded in water by the action of oxygen, heat, light, bacteria and microorganisms. Its decomposition pathway is generally through aconitic acid, itaconic acid, and citraconic anhydride, and then converted into carbon dioxide and water.
Comprehensive ability: Sodium citrate has good complexing ability for metal ions such as CA2+ and MG2+, and also has good complexing ability for other metal ions such as FE2+.
Other properties: Sodium citrate has excellent solubility, and its solubility increases with the increase of water temperature; sodium citrate has good pH adjustment and buffering properties. Sodium citrate is a weak acid and strong base salt, which can form a strong pH buffer when combined with citric acid, so it has important uses in some occasions where large pH changes are not suitable. In addition, sodium citrate also has excellent retarding and stability properties.

Sodium Citrate Uses:
Food:
Sodium citrate is mainly used as a food additive, with the largest demand. It can also be used as a flavoring agent, expander, stabilizer, preservative, buffer, and emulsifier. In addition, sodium citrate and citric acid can be used as flavoring agents, gelling agents and nutritional supplements for various pastries, cold drinks, juices, beverages, cold drinks, dairy products and jams.
Electroplating industry:
Because sodium citrate has good complexing properties, it is also very useful in the electroplating industry. The electroplating process is developing rapidly. Neutral citrate nickel plating has the advantages of environmental protection, pollution-free, easy maintenance, low corrosion, and excellent coating performance, so it has been used on a large scale in industrial production.
Construction industry:
In the construction industry, sodium citrate can be added as a retarder when making concrete, which can improve the antifreeze, compression and tensile properties of cement products. Under the social conditions where environmental problems are becoming increasingly serious, the sulfur dioxide in the exhaust gas of some smelters is seriously exceeded. Studies have shown that the use of sodium citrate's own characteristics to remove sulfides in industrial exhaust gas is effective.
Industrial cleaning:
Since sodium citrate can improve the decontamination effect when added to detergents, it has been widely used in the manufacture of phosphorus-free washing powder and liquid detergents. Studies have shown that special detergents containing sodium citrate are non-corrosive, so some precision instruments can also be cleaned with this special detergent. In the detergent industry, it can replace sodium tripolyphosphate as an auxiliary agent for non-toxic detergents.
Pharmaceutical industry:
It is used as an anticoagulant, expectorant and diuretic; it is also used in injections, photographic drugs, etc.
