Ammonium ferric citrate

Ammonium ferric citrate is a complex salt composed of iron, ammonia, and citric acid. It is a brown or greenish crystalline compound, soluble in water, forming a clear solution. Ammonium ferric citrate is widely used in various industries, including the food industry as a food additive and in the medical field for its iron-supplementing properties. It also finds applications in the photographic industry as a component of iron-based photographic film developers.

Uses

Food Industry

In the food industry, ammonium ferric citrate serves as a source of iron supplementation, helping to prevent or treat iron deficiency. It is recognized as safe by various health authorities and is added to foods and beverages as a nutrient additive. It is listed under the European food additive code E381.

Medical Field

Ammonium ferric citrate is used in the medical field primarily as an iron supplement. It is beneficial for individuals suffering from anemia or those at risk of iron deficiency. Its high bioavailability makes it an effective component in iron therapy, aiding in the replenishment of body iron stores.

Photographic Industry

In the photographic industry, ammonium ferric citrate is used in the process of cyanotype printing. It reacts with potassium ferricyanide to produce a light-sensitive solution that, when exposed to ultraviolet light, develops into a distinctive Prussian blue color. This process is utilized in the creation of blueprints and art prints.

Health and Safety

Ammonium ferric citrate is generally considered safe for consumption and use in various applications. However, as with all chemical compounds, appropriate handling and dosage guidelines should be followed to avoid potential side effects. Overconsumption of iron supplements, including those containing ammonium ferric citrate, can lead to iron overload, which may cause health issues.

Environmental Impact

The environmental impact of ammonium ferric citrate is minimal when used and disposed of properly. However, as with any chemical compound, care should be taken to prevent excessive release into the environment to avoid potential ecological effects.
