Sugar Substitutes | Acesulfame K


What is acesulfame K?

Acesulfame K (brand names: Sunett and Sweet One) is a no-calorie sugar substitute that is 200 times sweeter than sugar. It is also known as acesulfame potassium or Ace-K. It is often used in combination with other sweeteners.

Acesulfame K provides sweetness and enhances the flavor of food without adding the calories of sugar. Unlike sugar, it does not contribute to tooth decay. It also does not raise blood sugar levels. This may be helpful if you have diabetes and have to be careful about how much sugar you consume.

What products contain acesulfame K?

Acesulfame K can be found in a variety of processed foods and drinks, including baked goods, candy, frozen desserts, and soft drinks. It can also be used as a tabletop sweetener (for example, to sweeten a glass of iced tea). It is used in some medicines (for example, cough drops) and in oral hygiene products (for example, toothpaste and mouthwash).

Acesulfame K can be used in cooking and baking because it does not lose its sweet taste at high temperatures. For best results, follow the package instructions for using it in your recipes.

Is acesulfame K safe?

More than 90 studies have examined the safety of acesulfame K. It has been approved by the U.S. Food and Drug Administration (FDA) as a food additive since 1988. This means that the FDA has reviewed scientific evidence to be sure that it is safe for use in foods and drinks.

According to the National Cancer Institute, there is no evidence that acesulfame K and other sugar substitutes approved for use in the United States cause cancer or other serious health problems. Medical research studies have shown that these sweeteners are safe for most people when used in moderation.
