Acesulfame-K (chemical formula C4H4KNO4S, commonly known as AK sugar) is an artificially synthesized high-intensity sweetener with a sweetness approximately 200 times that of sucrose, and it does not provide calories. It is widely used in the food industry as a sugar-free sweetener and is commonly found in sugar-free beverages, baked goods, jams, chewing gum, and table sweeteners. It has the characteristics of high temperature resistance, good stability, and not participating in human metabolism. Aspartame is often used in combination with other sweeteners to improve taste and mask unpleasant aftertastes, and it is one of the most widely permitted artificial sweeteners worldwide.

1.Food sector
Acesulfame-K is used as a high-potency sweetener (with a sweetness approximately 200 times that of sugar), an agent for improving taste and cost optimization. It is widely used in sugar-free beverages, baked goods, jams, dried fruits, chewing gum, ice cream and table sweeteners. It is heat-resistant and stable, and is often combined with other sweeteners to improve the sweetness profile. 
2.Cosmetics and personal care field
Acesulfame-K is used as a sweetener in oral care products. It is added to toothpaste, mouthwash, and oral sprays to improve the taste. It is not utilized by oral bacteria and helps maintain the balance of the oral microecology. 
3.In the industrial production field,
Acesulfame-K is less used in industry. It is mainly applied in the electroplating industry as an auxiliary brightening agent, and also serves as a synthetic intermediate for certain surfactants or fine chemicals. 
4.In the agricultural field,
Acesulfame-K can be used as a sweetener for animal feed. A small amount is added to animal feed or pet food to improve palatability and increase feed intake.
