E150c: Ammonia caramel

What is E150c?

Ammonia caramel (E150c), also called Class III caramel, is a dark brown colouring made by controlled heating of sugars. Adding ammonium compounds during heating gives it particular colour and charge properties.

Origin and production

It is produced by heating food-grade carbohydrates such as glucose syrup or sucrose in the presence of ammonium compounds. Unlike burnt household caramel, it is made under carefully controlled industrial conditions.

Why is it used?

Ammonia caramel adds brown colour to sauces such as soy sauce and gravy, beers, some soft drinks, desserts and snacks. It is valued for its stability in products containing salt or proteins.

Vegan, vegetarian and halal

Ammonia caramel is made from sugars and mineral reagents and is suitable for vegans and vegetarians. It does not usually raise halal or kosher concerns.

Safety and regulation

Ammonia caramel is authorised in the EU, with specifications that limit by-products such as 4-methylimidazole. In its re-evaluation of caramel colours, EFSA identified a possible risk of exceeding the acceptable daily intake for some population groups, particularly high consumers.
