产品用途Product Usage



Sodium citrate isused as a flavoring agent and stabilizer in the food and beverage industry; itis used as an anticoagulant, phlegm and diuretic in the pharmaceuticalindustry; in the detergent industry, it can replace sodium tripolyphosphate asa non-toxic agent Detergent auxiliary; chemically an excellent chelating /complexing agent, industrial applications of sodium citrate all take advantageof this characteristic. It is also used in brewing, injections, photographicdrugs and electroplating.

Sodium citrate iscurrently the most important citrate. It is mainly produced by the fermentationof starch-based substances to produce citric acid, which is then neutralizedwith alkaline substances. Because the raw materials for the preparation ofsodium citrate are basically derived from grain, it is absolutely safe andreliable, and will not cause harm to human health. The Food and AgricultureOrganization of the United Nations and the World Health Organization do notplace any restrictions on their daily intake, and the product can be consideredto be drug-free. (2) Biodegradable. After the sodium citrate is diluted with alarge amount of water in nature, part of it becomes citric acid, and the twocoexist in the same system. Citric acid is easily biodegraded in water by theaction of oxygen, heat, light, bacteria and microorganisms. Its decompositionpathway is generally converted to carbon dioxide and water via aconitic acid,itaconic acid, and citraconic anhydride. (3) It has metal ion complexingability. Sodium citrate has good complexing ability to Ca2 +, Mg2 + and othermetal ions, and has good complexing ability to other metal ions, such as Fe2 +.(4) Excellent dissolving performance, and the solubility increases withincreasing water temperature. (5) Has good pH adjustment and bufferingperformance. Sodium citrate is a weak acid and strong alkali salt, which can becombined with citric acid to form a strong pH buffering agent, so it has itsimportant use in some occasions that are not suitable for large-scale pHchanges. In addition, sodium citrate also has excellent retardation andstability properties.



Should be placed in a cool and dry placeindoors, avoiding sun and rain.
