E950
Acesulfame is an artificial sweetener in the form of white crystalline powder. It is completely free of calories and 180-200 times sweeter than sugar.
It is also known as acesulfame K or Ace K (K as a symbol for potassium). It was accidentally discovered in 1967. by German chemist Karl Clauss. “United States Food and Drug Administration approved its usage in 1993., while EU approved it in 1991.
In production of soft drinks, acesulfame is almost always used in combination with other sweeteners (e.g. aspartame, cyclamate and saccharin), which results with synergistic effect finished products. It is also used as a sweetener in pharmaceutical products.
In high concentration, acesulfame leaves bitter “aftertaste” which is one of the reasons for mentioned mixing with other sweeteners. Research shows that it is safe to consume acesulfame if concentration in any form is less than 3 %.
