Aspartame is an amino acid-based artificial sweetener approximately 200 times sweeter than sugar, known for its clean, sugar-like taste with minimal aftertaste. It is widely used in sugar-free foods and beverages but is not suitable for cooking or baking due to heat sensitivity. Its pleasant flavor and low calorie content make it a popular choice for reducing sugar intake without compromising sweetness. As consumer demand for healthier options grows, aspartame remains a staple sweetener in many low-calorie and diet products globally.
