Sodium citrate

Sodium citrate may refer to any of the sodium salts of citric acid (though most commonly the third):Mono sodium citrateDi sodium citrateTri sodium citrateAs food additives, the 3 forms of the salt are also collectively known by the E number E331.

Trisodium citrate has the chemical formula of Na3C6H5O7.It is some times referred to simply as sodium citrate, though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. For this reason, citrates of certain alkaline and alkaline earth metals (e.g. sodium and calcium citrates) are commonly known as "sour salt" (occasionally citric acid is erroneously termed sour salt).

White to off-white crystalline powder

Sodium citrate is odorless and has a pleasant, acid taste. Sodium citrate is anhydrous or contains two molecules of water of crystallization

ChEBI: Sodium citrate is the trisodium salt of citric acid. It has a role as a flavouring agent and an anticoagulant. It contains a citrate(3-).

Alkalizer (systemic).

sodium citrate may be used in cosmetic formulations as an alkalizer and to bind trace metals in solutions (by means of a chelating action). It is the sodium salt of citric acid.

Sodium Citrate is a buffer and sequestrant obtained from citric acid as sodium citrate anhydrous and as sodium citrate dihydrate or sodium citrate hydrous. the crystalline products are prepared by direct crystallization from aqueous solutions. sodium citrate anhy- drous has a solubility in water of 57 g in 100 ml at 25°c, while sodium citrate dihydrate has a solubility of 65 g in 100 ml at 25°c. it is used as a buffer in carbonated beverages and to control ph in preserves. it improves the whipping properties in cream and pre- vents feathering of cream and nondairy coffee whiteners. it pro- vides emulsification and solubilizes protein in processed cheese. it prevents precipitation of solids during storage in evaporated milk. in dry soups, it improves rehydration which reduces the cooking time. it functions as a sequestrant in puddings. it functions as a complexing agent for iron, calcium, magnesium, and aluminum. typical usage levels range from 0.10 to 0.25%. it is also termed trisodium citrate.

Trisodium Citrate is a buffer and sequestrant that is the trisodium salt of citric acid. see sodium citrate.

Sodium citrate is also known as citrate of soda, the white crystals or granular powder was obtained by neutralizing citric acid with sodium carbonate. It is soluble in water but less so in alcohol. Sodium citrate was used as a preservative in albumen papers.
