How much is permitted

A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

Australia and New Zealand—57 GMP
Canada—6 GMP, 1 no quantity stated
European Union—46 several limits, 14 quantum satis, 24 no quantity stated
Great Britain—80 quantum satis, 1 no quantity stated
Japan—1 no quantity stated
South Korea—1 no quantity stated
United States—1 no quantity stated
Codex Alimentarius—21 GMP

No regulator sets a figure for Tripotassium citrate. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.

What it is made from

Made by neutralising fermentation-derived citric acid with potassium hydroxide or carbonate.

The two specifications, compared

The European Union sets identity and purity by regulation; JECFA publishes its own through FAO, advisory until a country adopts it. Both documents are below in full. These are the parameters each puts a number on.

ParameterEuropean UnionJECFA
Assayno less than 99 %no less than 99 %
Loss on dryingno more than 6 %no more than 6 %
Leadno more than 1 mg/kgno more than 2 mg/kg
Arsenicno more than 1 mg/kg—
Mercuryno more than 1 mg/kg—

One parameter differs between the two documents. A difference is not a disagreement about safety: the two are revised on their own cycles, and an assay or a drying loss can be measured against a different preparation of the substance, which is why only the contaminant ceilings are marked. Within the EU the EU's figure is the one that binds.

How the EU defines it

The legal specification an additive must meet to be sold as this E number in the EU — what it is, how it may be made, and the purity it must reach. From Commission Regulation (EU) No 231/2012.

How JECFA defines it

INS 332(ii) Tripotassium Citrate

Synonyms: Potassium citrate; INS No. 332(ii)

Assay, identification and purity criteria

Description and assay

Specification history
Prepared at the 19th JECFA (1975), published in NMRS 55B (1976) and in FNP 52 (1992). Metals and arsenic specifications revised at the 59th JECFA (2002). An ADI not limited' was established at the 17th JECFA (1973)
Chemical names
Tripotassium citrate, tripotassium salt of 2-hydroxy-1,2,3-propanetricarboxylic acid, tripotassium salt of ß-hydroxy-tricarballylic acid
C.A.S. number
866-84-2
Formula weight
324.42
Assay
Not less than 99.0% after drying
DESCRIPTION
Deliquescent, odourless, transparent crystals or white, granular powder
FUNCTIONAL USES
Sequestrant, stabilizer, buffer
METHOD OF ASSAY
Weigh accurately about 250 mg of the dried sample. Dissolve in 40 ml of glacial acetic acid, warming slightly to effect solution. Cool the solution to room temperature, add 2 drops of crystal violet TS, and titrate with 0.1 N perchloric acid. Perform a blank determination and make any necessary correction. Each ml of 0.1 N perchloric acid is equivalent to 10.21 mg of C 6 H 5 K 3 O 7 .

Identification

Solubility (Vol. 4)
Very soluble in water, insoluble in ethanol
Test for citrate
To 5 ml of a 1 in 10 solution of the sample add 1 ml of calcium chloride TS and 3 drops of bromothymol blue TS, and slightly acidify with dilute hydrochloric acid TS. Add sodium hydroxide TS until the colour changes to a clear blue, then boil the solution for 3 min, agitating gently during the heating period. A white, crystalline precipitate appears which is insoluble in sodium hydroxide TS but dissolves in acetic acid TS. To 10 ml of a 1 in 10 solution of the sample add 1 ml of mercuric sulfate TS. Heat the mixture to boiling and add a few drops of potassium permanganate TS. A white precipitate is formed.
Test for potassium
When hydrochloric acid is present, a solution of the sample gives with platinum chloride TS a yellow crystalline precipitate (which on ignition leaves a residue of potassium chloride and platinum).

Purity criteria

Loss on drying (Vol. 4)
Not more than 6% (180 o , 4 h)
Alkalinity
A 1 in 20 solution of the sample is alkaline to litmus. After the addition of 0.2 ml of 0.1 N sulfuric acid and 1 drop of phenolphthalein TS to 10 ml of the solution no pink colour is produced.
Oxalate
To 10 ml of a 1 in 10 solution of the sample add 5 drops of dilute acetic acid TS and 2 ml of calcium chloride TS. No turbidity develops within 1 h.
Lead (Vol. 4)
Not more than 2 mg/kg Determine using an atomic absorption technique appropriate to the specified level. The selection of sample size and method of sample preparation may be based on the principles of the method described in Volume 4, “Instrumental Methods.”

Common questions

Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.

What is INS 332(ii)?
INS 332(ii) is Tripotassium citrate. Tripotassium citrate is an acidity regulator and emulsifying salt used where a sodium-free alternative to trisodium citrate is needed.
What is Tripotassium citrate used for in food?
It is listed as an acidity regulator — the role Canada, Codex and the US assign it. This page shows every function each regulator records, with the citation for each.
Where is Tripotassium citrate permitted?
Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, Japan, South Korea, the US and the Codex standard permit it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
Is Tripotassium citrate vegan?
Yes. Tripotassium citrate is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
