Explain about the Acesulfame K - Artificial Sweeteners?

Acesulfame-K (potassium salt of 6-methyl-1, 2, 3-oxathazin-4(3H)-one 2, 2 dioxide) is a sweetener which is commonly used in dry mixes, table uses and chewing gum. It is 200 times as sweet as sugar and it is not metabolised and is thus non-caloric. Food products often contain a mixture of sweeteners. This is because it has been found that they have a synergistic effect whereby the sweetness of a mixture is greater than that of the individual components. This means that less amount can be used to get the same apparent sweetness.
