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.

E 155 Brown ht

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 “Brown HT”, among the additives given priority within its class.

Hazard reference values

EFSA and JECFA have both set an acceptable daily intake for Brown HT, and they agree: 1.5 mg/kg bw/day. An acceptable daily intake is a reference value set by a committee, not a threshold above which harm begins. See where the two committees differ.

Values set by assessing bodies. A body that has not set a value is not listed here.

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.

  1. EFSA 2014

    In a refined exposure assessment for Brown HT (E 155), EFSA found that high-level exposure based on maximum permitted levels exceeded the ADI of 1.5 mg/kg bw/day for all age groups except the elderly, but that mean and high exposure based on reported use levels only were below the ADI for all population groups.

    Source document

  2. EFSA 2010

    The ANS Panel derived an ADI of 1.5 mg/kg bw/day for Brown HT (E 155) from a long-term mouse study (the SCF had previously set 3 mg/kg bw/day). It concluded that mean intake estimates were generally below the ADI, but that high-percentile exposure in adults and children aged 1–10 could exceed it at the upper end of the range.

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 155?
E 155 is Brown HT. Brown HT is a synthetic brown azo dye used mainly in chocolate-flavoured baked goods, where it substitutes for cocoa colour.
What is Brown HT used for in food?
It is listed as a colour — the role Codex and the EU assign it. This page shows every function each regulator records, with the citation for each.
Where is Brown HT permitted?
Of the seven regulators this site reads, Australia and New Zealand, the EU, Great Britain 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 Brown HT vegan?
Yes. Brown HT is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
