The characteristics and uses of sodium citrate
In daily life, sodium citrate appears in the raw materials of various items around us. How many people have known about it, do you know some of its functions, characteristics, and uses? Let's take a look at some of its secrets.
Sodium citrate is currently the most important citrate. It is mainly produced by fermenting starch-based substances to produce citric acid, and then neutralizing it with alkaline substances. It has the following excellent properties:
(1) Safe and non-toxic performance. Since the raw materials for the preparation of sodium citrate basically come from grain, it is absolutely safe and reliable, and will not cause harm to human health. The United Nations Food and Agriculture and the World Health Organization do not impose any restrictions on their daily intake, and the product can be considered drug-free.
(2) 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. The decomposition method is generally through aconitic acid, itaconic acid, and citraconic anhydride to convert to carbon dioxide and water.
(3) It has the ability to complex metal ions. Sodium citrate has good complexing ability to Ca2+, Mg2+ and other metal ions, and it also has good complexing ability to other metal ions, such as Fe2+ ions.
(4) Excellent solubility, and the solubility increases with the increase of water temperature.
