Ferric Ammonium Citrate, Brown FCC Food Grade
Iron Ammonium Citrate
INS: 381 CAS: [1185-57-5]
Ferric Ammonium Citrate, Brown, occurs as thin, transparent brown, red-brown, or garnet red scales or granules, or as a brown-yellow powder. It is a complex salt of undetermined structure, composed of iron, ammonia, and citric acid. It is very soluble in water, but is insoluble in alcohol. The pH of a 1:20 aqueous solution is about 5.0 to 8.0. It is deliquescent in air and is affected by light.
A. A 500-mg sample, when ignited, chars and leaves a residue of iron oxide.
B. Add 0.3 mL of potassium permanganate TS and 4 mL of mercuric sulfate TS to 5 mL of a 1:10 aqueous solution, and heat the mixture to boiling. A white precipitate forms.
C. Dissolve about 500 mg of sample in 5 mL of water, and add 5 mL of 1 N sodium hydroxide. A red-brown precipitate forms, and ammonia is evolved when the mixture is heated.
Assay: Not less than 16.5% and not more than 18.5% of iron (Fe).
Ferric Citrate: Passes test.
Lead: Not more than 2 mg/kg.
Mercury: Not more than 1 mg/kg.
Oxalate: Passes test.
Sulfate: Not more than 0.3%.
Ferric Ammonium Citrate USP
Ferric Ammonium Citrate contains not less than 16.5 percent and not more than 18.5 percent of iron (Fe).
A: Ignite about 0.5 g: it chars, and leaves a residue of iron oxide.
B: To 10 mL of a solution of Ferric Ammonium Citrate (1 in 100) add 6 N ammonium hydroxide drop wise: the solution darkens, but no precipitate forms.
C: To 5 mL of a solution of Ferric Ammonium Citrate (1 in 100) add 0.3 mL of potassium permanganate TS and 4 mL of mercuric sulfate TS, and heat the mixture to boiling: a white precipitate forms.
Ferric citrate: To a solution of Ferric Ammonium Citrate (1 in 100) add potassium ferrocyanide TS: no blue precipitate is formed.
Sulfate: 0.3% Maximum.
Oxalate: Transfer 1 g to a 125-mL separator, dissolve in 10 mL of water, add 2 mL of hydrochloric acid, and extract successively with one 50-mL portion and one 20-mL portion of ether. Transfer the combined ether extracts to a 150-mL beaker, add 10 mL of water, and remove the ether by evaporation on a steam bath. Add 1 drop of glacial acetic acid and 1 mL of calcium acetate solution (1 in 20): no turbidity is produced within 5 minutes.
Mercury: not more than 10 µg per g is found..
Limit of lead: not more than 10 µg per g is found.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".
He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
