Advantages of sodium citrate performance and use
Sodium citrate, white crystal or granular powder. Odorless, cool, salty and spicy. Normal temperature and air are slightly soluble in humid air, and weathering occurs in hot air. It is soluble in water but insoluble in ethanol. The aqueous solution is weakly alkaline. Sodium citrate is the most important kind of citrate in the industry at present. It has a wide range of uses and can be used in food, medicine, environmental protection, electroplating and brewing industries.

Performance and use of sodium citrate
1. The performance of sodium citrate
Sodium citrate is the most important citrate at present. It is mainly produced by fermenting starch-based substances to produce citric acid, and then neutralizing with alkaline substances. It has a variety of unique and excellent properties.
(1) Safe and non-toxic performance.
(2) It has good pH adjustment and buffering performance.
(3) Excellent solubility, and the solubility increases with the increase of water temperature;
(4) It is biodegradable. After sodium citrate is diluted with a large amount of water in nature, part of it becomes 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.
2. Uses of sodium citrate
Sodium citrate has the above-mentioned various excellent properties, making it have a very wide range of uses. At present, citric acid and its sodium citrate are widely used in the food industry, pharmaceutical industry, chemical industry and other fields
2.1 In terms of food, sodium citrate is used as a food additive and has the greatest demand. It is mainly used as a flavoring agent, buffer, emulsifier, expansion agent, stabilizer and preservative, etc.; in addition, sodium citrate is compatible with citric acid for use Gelling agents, nutritional supplements and flavors for various jams, jellies, fruit juices, beverages, cold drinks, dairy products and pastries.
2.2 In medicine, sodium citrate is also widely used. Utilizing the properties of citrate and calcium ions to form soluble complexes, it can be used as an anticoagulant and blood transfusion agent to preserve and process blood products. Sodium citrate is used as a preservative and used to preserve syrups and other medicines. When sodium citrate is injected, it is used to correct the acidity of blood, body fluids and urine, as a phlegm-resolving agent, diuretic and phlegm-resolving agent, etc., just like methyl salt.

2.3 Adding a certain amount of sodium citrate to the detergent can significantly increase the decontamination ability of the detergent. Liquid detergents containing sodium citrate have excellent washing performance. For example, some special detergents containing sodium citrate are not corrosive to some metal appliances; some special detergents containing sodium citrate clean the appliances, the metal surface is as bright as new, and the waste liquid after cleaning can be regenerated and repeated Utilize, reduce washing cost.
2.4 Sodium citrate has good complexing properties, so it is widely used in the electroplating industry; in the construction industry, sodium citrate can be added to concrete as a retarder to improve the tensile, compression and frost resistance of cement products performance;
2.5 In terms of environmental protection, sodium citrate can be used to remove sulfides from industrial exhaust gas. In the ceramic industry, sodium citrate can be used as a grinding aid additive. In addition, sodium citrate has new uses in brewing and photography, which further broadens the application fields of sodium citrate.
