E150d: Sulphite ammonia caramel
What is E150d?
Sulphite ammonia caramel, labelled E150d, is a dark brown colouring and the most widely used class of caramel colour. It carries a negative electrical charge, which keeps it stable in acidic drinks.
Origin and production
It is made by heating sugars such as glucose syrup or sucrose in the presence of both ammonium and sulphite compounds.
Why is it used?
E150d gives the deep brown colour of colas and many other soft drinks and is also used in some balsamic vinegars, sauces, biscuits and beers. It is chosen for its intense colour and stability in acidic conditions.
Vegan, vegetarian and halal
Sulphite ammonia caramel is made from sugars and mineral reagents and is suitable for vegans and vegetarians. It is not generally a halal or kosher concern.
Safety and regulation
E150d is authorised as a food colour in the EU and was re-evaluated by EFSA, which did not identify a risk of exceeding the acceptable daily intake from its use. EU specifications set limits for by-products formed during manufacture, such as 4-methylimidazole.
