Aspartame is a high-intensity sweetener about 200 times sweeter than sucrose, delivering sweetness with very low caloric value.

It is widely used in sugar-free beverages, table-top sweeteners, chewing gum, confectionery, oral care, and flavored pharmaceutical preparations.

Aspartame provides a clean sweetness profile and is often blended with other sweeteners to improve taste, stability, and cost-effectiveness.

It is suitable for reduced-sugar and weight-management products; however, it is not recommended for individuals with phenylketonuria due to its phenylalanine content.
