Ammonium ferric citrate

Uses1. Nutritional supplements. Iron enhancer, anti-anemia iron agent (each oral 1~2g). It can be added to biscuits, milk powder, being not suitable for being applied to food that is not colored. 2. Ammonium ferric citrate, as a food iron fortifier, has its absorption effect be better than inorganic iron. China provides that it can be used for salt and sandwich sugar with the usage amount of 4000~8000mg/kg; in high-iron cereal and its products (daily limit: 50 g of such food): 1200~1350mg/kg; dairy and infant food: 400 to 800 mg/kg; in cereals and their products, 160 to 330 mg/kg; beverages: 70 to 140 mg/kg. 3. It can be used for the pharmaceutical industry 4. It is used in the photographic industry and the pharmaceutical industry 5. It can be used as the nutritional supplements (iron fortifier). For dairy products, bread and wheat flour. Also used as anti-caking agent. 6. It can be used in bacterial culture medium for measuring aluminum, photography, blue print, blood and so on. 7. The brown product can be used as a hematinic drug for the treatment of iron deficiency anemia; it can be used as food additives; according to the provision of Japanese, "Food Additives", iron content: 16.5%-21.2%. The brown product and green product are both chemical-sensitive substances with the green goods being more sensitive to light than brown goods. Paper coated with green ferric ammonium citrate and red blood salt (potassium ferricyanide) is called blue blueprint paper. Upon the exposure, the trivalent iron in the citric acid salt is converted to bivalent, coming across water to give turnbull's blue, so the lightened part exhibits blue color while the rest part is still white, yielding a blue matrix white line pattern.

DescriptionAmmonium ferric citrate is a food additive with E number E381 used as an acidity regulator. It is a green or reddish-brown powder which is very soluble in water. The molecular formula of ammonium iron (III) citrate is variable. It can be prepared by adding Fe(OH)3 to an aqueous solution of citric acid and ammonia . The brown form is approximately 9% NH3, 16.5 – 18.5 % Fe , and 65 % hydrated citric acid; the green form is approximately 7.5 % NH3 , 14.5 – 16 % Fe, and 75% hydrated citric acid. The green type is more readily reduced by light than the brown. Other uses for ammonium ferric citrate include water purification and printing (cyano type). It is used as a reducing agent of metal salts of low activity like gold and silver and is also in a commonly used recipe with potassium ferricyanide to make cyanotype prints. Ammonium ferric citrate is also used in Kligler iron deeps to determine hydrogen sulfide production in microbial metabolism. In medicine, ammonium ferric citrate is used as a contrast medium. It is also used as a hematinic.

UsesHematinic

UsesFor blueprints; in photography.

UsesFerric Ammonium Citrate is a nutrient supplement that is a source of iron. It is prepared by the reaction of ferric hydroxide with citric acid, followed by treatment with ammonium hydroxide, evaporation, and drying. The resulting product occurs in two forms, i.e., brown with 16.5–18.5% iron and ferric ammonium citrate, green with 14.5–16% iron.

UsesIron Ammonium Citrate is an anticaking agent used in salt. It is the chemical green ferric ammonium citrate.

General DescriptionAmmonium ferric citrate is a yellowish brown to red solid with a faint odor of ammonia. Ammonium ferric citrate is soluble in water. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Ammonium ferric citrate is used in medicine, in making blueprints, and as a feed additive.
