Wholesale Food Grade Ferric Citrate CAS 3522-50-7
Product Introduction to Ferric Citrate
Ferric citrate is a reddish-brown crystalline or powdery inorganic compound formed by citric acid and ferric ions. It usually exists as a hydrate and has a slightly rusty taste. Ferric citrate has dual functional applications: in the pharmaceutical field, it is used as an oral iron-based phosphate binder; in the food industry, it is widely used as an iron fortifier and acidifier in bread, dairy products, etc., to prevent iron-deficiency anemia and to optimize food flavor and color. Additionally, it is used as a mineral supplement in animal feed.

Ferric citrate also has potential applications in cosmetics and other fields.
Common Production Methods of Ferric Citrate
Method 1
Citrate acid is added to a ferric hydroxide solution, heated to below 60°C, evaporated and concentrated to a slurry, and dried at low temperature on a glass plate.
Method 2
Ammonia water is added to a ferric sulfate solution to form ferric hydroxide precipitate. The reaction mixture is filtered and washed with water until no sulfuric acid is present. Citric acid is added to the above reaction mixture, and the reaction mixture is heated to 60°C with stirring to completely dissolve the precipitate. The mixture is then filtered. The filtrate is concentrated to a syrupy state by heating below 60°C, coated onto a glass plate to form a thin layer of small leaves, peeled off, slightly warmed, and dried to obtain the target product, ferric citrate.
