E150b: Caustic Sulphite Caramel
Main role: brown coloring
Also listed as: Class II caramel, sulfite caramel
What is E150b (Caustic Sulphite Caramel)?
E150b is a caramel color made by heating carbohydrates with sulfite compounds. It belongs to Class II caramel and differs from plain caramel E150a in its production conditions. Its main purpose is brown coloring rather than adding caramel sweetness.
What does it do in food?
Its main role is brown coloring. Coloring changes appearance. It does not establish the amount of fruit, vegetables, vitamins, or minerals in a serving. Different pigment preparations can have different processing properties and permitted uses.

Label names and ingredient questions
Look for E150b, E 150b, or the ingredient name. Related names and label terms include Class II caramel, sulfite caramel. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Caramel color is not the same ingredient as caramel candy or caramel flavor. A Class II label helps distinguish the processing route, but does not disclose the amount in the food.
Is E150b safe?
There is no meaningful personal risk estimate from an E number alone. Food-grade specifications, allowed uses, amount consumed, and individual circumstances all matter. The authorization record below gives the legal scope; it is not a claim that every possible use is appropriate.
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
Authorization and conditions of use
The Great Britain food additive register lists E150b as Caustic sulphite caramel. This is an entry subject to its stated conditions, not unrestricted permission for every food. The record links to the applicable authorization terms. For an EU product, use the European Commission food additive database to check the relevant food category and limits. Other countries may use different names or rules.
