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.

Canada—5 GMP
European Union—46 several limits, 22 no quantity stated
Great Britain—66 quantum satis
Codex Alimentarius—2 GMP

No regulator sets a figure for Sodium hydrogen sulfate. 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.

GRAS notices to the FDA

A GRAS notice is a company’s conclusion that a substance is generally recognised as safe for the use it describes. FDA’s letter responds to that conclusion, for that notifier and that use. It is not a listing in 21 CFR, and it is not counted as a US permission above. The substance and use are as FDA’s inventory words them; this site matched the notice to this page by exact name.

  • GRN No. 3 · Sodium bisulfate · Jones Hamilton Co.

    Intended use: Use in cake mixes as a pH control agent and a leavening agent at a level of 0.1 to 1.0 percent by weight; use in foods in general as a pH control agent and processing aid at levels not to exceed good manufacturing practices

    FDA’s response (1998-06-05): FDA has no questions

What it is made from

Produced by reacting sodium chloride or sulfate with sulfuric acid. Despite the similar name it is not a sulphite and does not carry the sulphite declaration requirement.

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 95.2 %no less than 85 %
Loss on dryingno more than 0.8 %no more than 0.8 %
Leadno more than 2 mg/kgno more than 2 mg/kg
Arsenicno more than 3 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

The international specification for identity and purity, prepared by the Joint FAO/WHO Expert Committee on Food Additives and published by FAO. It is a different document from any above, written by a different body and revised on its own cycle; it is advisory, and a country adopts it or does not.

INS 514(ii) Sodium hydrogen sulfate

Sodium chloride and sulfuric acid are combined at elevated temperatures to produce molten sodium hydrogen sulfate. The molten sodium hydrogen sulfate is sprayed and cooled to form a solid product with uniform particle size.

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 2019

    The FAF Panel found no concern for genotoxicity or carcinogenicity for sulphuric acid and its sodium, potassium, calcium and ammonium salts (E 513–E 517), noting exposure far below doses causing laxative effects in humans. It concluded that exposure does not raise a safety concern at reported uses and use levels and that no numerical ADI is needed.
