E950: Acesulfame k
What is E950?
Acesulfame K (E950), or acesulfame potassium, is a calorie-free high-intensity sweetener about 200 times sweeter than sugar. It is a small synthetic molecule that passes through the body without being metabolised.
Origin and production
It is produced by chemical synthesis from compounds derived from acetoacetic acid, finishing with the formation of a stable potassium salt.
Why is it used?
Acesulfame K is used in diet soft drinks, powdered drink mixes, sugar-free chewing gum and confectionery. It is frequently blended with sucralose or aspartame because the combination gives a more sugar-like taste and masks its slight bitter aftertaste.
Vegan, vegetarian and halal
Acesulfame K is synthesised without animal ingredients and is suitable for vegans and vegetarians. It raises no particular halal or kosher issue.
Safety and regulation
Acesulfame K is authorised as a sweetener in the EU with maximum levels for specific foods and has been evaluated by EFSA, most recently in a re-evaluation of its safety. As with other intense sweeteners, its use is restricted in foods for infants and young children.
