Product introduction：

Sodium citrate, also known as sodium citrate, is white crystalline granules or powder at room temperature, odorless, has a cool and salty taste, and is stable in the air. The relative density is 1.857 (23.5°C). It loses water of crystallization at 15Chemicalbook0°C and decomposes when heated continuously. Soluble in water, the pH of the aqueous solution is about 8, hardly soluble in ethanol. It is

What is application of Sodium citrate ?

When fresh blood is taken clinically, some sterilized sodium citrate needs to be added to prevent blood coagulation, so sodium citrate is called an anticoagulant. It is used as a flavoring agent and stabilizer in the food and beverage industry; it is used as an anticoagulant, expectorant and diuretic in the pharmaceutical Chemicalbook industry; in the detergent industry, it can replace sodium tripolyphosphate as an auxiliary agent for non-toxic detergents; it is also used in brewing, injections, photographic medicines and electroplating, etc. It is one of the basic pharmaceuticals for biological experiments.

Difference between sodium citrate and citric acid?

1. Different appearance: sodium citrate is white cubic crystal or granular powder, while citric acid is colorless translucent crystal or white granule or white crystalline powder.
2. The taste is different: sodium citrate has a salty taste and a little spicy taste, while citric acid has only a sour taste.
3. Different uses: Sodium citrate is used in flavoring agent, buffer, gelling agent, toner, while citric acid is used in cosmetics, jams, refreshing drinks, etc.
4. Different properties: citric acid is an important organic acid, and its calcium salt is easier to dissolve in cold water than hot water; while sodium citrate is mainly produced by fermentation of starchy substances, which has many unique and excellent properties.
5. Different physical and chemical properties: citric acid can exist in the form of anhydrous or monohydrate, and it will decompose to obtain anhydrate when heated to a certain extent; while sodium citrate is relatively stable in the air, it has no melting point and boiling point.

How to Use Sodium citrate?

food application

Sodium citrate is used in refreshing drinks to ease the sour taste and improve the taste. Adding this product in brewing can promote saccharification, and the dosage is about 0.3%. In the manufacture of sorbet and ice cream, sodium citrate can be used as an emulsifier and stabilizer at a dosage of 0.2% to 0.3%. This product can also be used as an anti-rancidity agent for dairy products, a thickener for processed cheese and fish products, and a sweetness corrector for food.

medical application

In medicine, sodium citrate is also widely used. Utilizing the characteristic that citrate and calcium ion can form a soluble complex, it can be used as an anticoagulant and blood transfusion agent to preserve and process blood products. Sodium citrate is used as a preservative to preserve medicines such as syrups. Sodium citrate is the same as potassium salt when injected, and 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 application

Sodium citrate has the characteristics of good water solubility, excellent chelating ability for metal ions such as Ca2+ and Mg2+ in water, biodegradation, strong dispersion ability and strong anti-redeposition ability, so it is gradually becoming a substitute for sodium tripolyphosphate and is used to produce phosphorus-free laundry detergent, especially phosphorus-free liquid detergent. Adding a certain amount of sodium citrate to the detergent can significantly increase the decontamination ability of the detergent.
