According to the Internet, it turns out to be the same, but is this so?
Answer
Dear Ms,
aspartame and Acesulfame K are two completely different molecules. They also belong to two other classes of artificial sweeteners. Aspartame belongs to the peptide derivatives (a peptide is a piece of a protein), acesulfame belongs to the sulfamates. They have about the same sweetening power (200 times sweeter than sugar), but different stability: acesulfame K is more stable, especially in acidic medium than aspartame. Acesulfame K is also prone to a metallic aftertaste, which is of course undesirable; therefore it is usually combined with aspartame. Below you will find the structures:
Acesulfame K
Aspartame
Hopefully this has helped you.
