No sugar?Why pepsi max or diet coke still sweet?

"Bakit matamis pa rin ang pepsi max or diet coke kahit walang sugar?" The secret lies in this sweeteners..

The ingredient: acesulfame potassium—is combined with aspartame to provide the beverage's sweetness.

Acesulfame potassium is a calorie-free artificial sweetener, also known as Acesulfame K or Ace K (K being the symbol for potassium), and marketed under the trade names Sunett and Sweet One. It was discovered accidentally in 1967 by German chemist Karl Clauss at Hoechst AG (now Nutrinova).^[1] Chemically, acesulfame potassium is the potassium salt of 6-methyl-1,2,3- oxathiazine-4(3H)-one 2,2-dioxide. It is a white crystalline powder with molecular formula C₄H₄KNO₄S and a molecular weight of 201.24.
Acesulfame K is 180-200 times sweeter than sucrose (table sugar), as sweet as aspartame, about half as sweet as saccharin, and one-quarter the sweetness of sucralose. Like saccharin, it has a slightly bitter aftertaste, especially at high concentrations. Kraft Foods has patented the use of sodium ferulate to mask acesulfame's aftertaste.^[3] Alternatively, acesulfame K is often blended with other sweeteners (usually sucralose or aspartame). These blends are reputed to give a more sugar-like taste where each sweetener masks the other's aftertaste, and/or exhibit a synergistic effect wherein the blend is sweeter than its components.

Aspartame is the name for an artificial, non-saccharide sweetener,This sweetener is marketed under a number of trademark names, including Equal, NutraSweet, Canderel, and is an ingredient of approximately 6,000 consumer foods and beverages sold worldwide. It is commonly used in diet soft drinks, and is often provided as a table condiment. It is also used in some brands of chewable vitamin supplements and common in many sugar-free chewing gums. However, aspartame is not always suitable for baking because it often breaks down when heated and loses much of its sweetness. Aspartame is also one of the sugar substitutes used by people with diabetes.
