Amaranth is a synthetic dark red azo dye. It was certified in the United States as FD&C Red No. 2 until the FDA revoked that listing in 1976; it remains permitted in the European Union for a small number of uses, chiefly aperitif wines and fish roe.

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 | 30 mg/kg – 300 mg/kg | 15 numeric limit |
|---|---|---|
| Canada | — | 1 GMP, 19 no quantity stated |
| European Union | 30 mg/kg – 100 mg/kg | 5 numeric limit |

What FDA’s inventory records
This page holds no listing for Amaranth in the parts of 21 CFR this site reads. FDA’s Substances Added to Food inventory does carry it, as FD&C RED NO. 2--DELISTED — marked delisted, pointing at the provisional colour listings, where terminations are recorded: 21 CFR 81.10, 21 CFR 81.30.
The inventory is an information resource: a row means FDA holds information about the substance’s use in food, not that the substance is listed for that use. It is shown apart from the permissions above and is not counted as a US permission anywhere on this site.
What it is made from
A trisulfonated azo dye synthesised from petroleum-derived aromatic intermediates. It shares a name with the amaranth plant but has no connection to it.

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.
| Parameter | European Union | JECFA |
|---|---|---|
| Assay | no less than 85 % | — |
| Lead | no more than 2 mg/kg | — |
| Arsenic | no more than 3 mg/kg | — |
| Mercury | no more than 1 mg/kg | — |
| Cadmium | no more than 1 mg/kg | — |
The two documents state the same figures for every parameter compared here.
How the EU defines it

E 123 Amaranth
Amaranth consists essentially of trisodium 2-hydroxy-1-(4-sulfonato-1-naphthylazo) naphthalene-3,6-disulfonate and subsidiary colouring matters together with sodium chloride and/or sodium sulphate as the principal uncoloured components. Amaranth is manufactured by coupling 4-amino-1-naphthalenesulphonic acid with 3-hydroxy-2,7-naphthalenedisulphonic acid. Amaranth is described as the sodium salt. The calcium and the potassium salt are also permitted.

The EU re-evaluation programme
Every additive authorised in the EU before 20 January 2009 was put back through EFSA by Commission Regulation (EU) No 257/2010, and this one is named in it. What the Regulation required is below; whether the opinion has since been published is not something this site records.
- To be evaluated by 15 April 2010. Named in Annex II, Part I, point 1 as “Amaranth”, among the additives given priority within its class.
Hazard reference values
The two committees set different figures. EFSA's acceptable daily intake is 0.15 mg/kg bw/day; JECFA's is 0.5 mg/kg bw/day (1984). An acceptable daily intake is a reference value set by a committee, not a threshold above which harm begins. The lower figure is not a finding that the other body was wrong: the two work to different terms of reference, on their own timetables, and sometimes from different data. This site states both and chooses between them nowhere. See where the two committees differ.
| Type | Value | Population | Assessed by | Opinion |
|---|---|---|---|---|
| ADI | 0.5 mg/kg bw/day | — | JECFA | 1984 |
| ADI | 0.15 mg/kg bw/day | consumers | EFSA | not identified in the dataset |
Evidence and how bodies read it
What assessing bodies concluded
Each conclusion is paraphrased in the body's own framing, from the published opinion linked beneath it. Where bodies differ, both stand; this site does not adjudicate between them or add a view of its own.
EFSA 2013
In a refined exposure assessment for amaranth (E 123), EFSA estimated high-level adult exposure about 15 times lower than in 2010, and found that exposure estimates for children, adults and the elderly remained below the ADI of 0.15 mg/kg bw/day.
EFSA 2010
The ANS Panel re-evaluated Amaranth (E 123) and established an ADI of 0.15 mg/kg bw/day, lower than the previous SCF (0.8) and JECFA (0.5) values. It estimated that children's exposure was well below this ADI, but that high-percentile adult exposure could be up to six times higher, driven mainly by aperitif wines and Americano.
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 E 123?
- E 123 is Amaranth. Amaranth is a synthetic dark red azo dye. It was certified in the United States as FD&C Red No. 2 until the FDA revoked that listing in 1976; it remains permitted in the European Union for a small number of uses, chiefly aperitif wines and fish roe.
- What is Amaranth used for in food?
- It is listed as a colour — the role Canada, Codex and the EU assign it. This page shows every function each regulator records, with the citation for each.
- Where is Amaranth permitted?
- Of the seven regulators this site reads, Australia and New Zealand, Canada, the EU, Great Britain, Japan, South Korea 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 Amaranth vegan?
- Yes. Amaranth is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
