Usage

General Description

Beta-Aspartame, chemically known as L-alpha-Aspartyl-L-phenylalanine methyl ester, is a dipeptide ester and an aspartic acid ester. It is a low-calorie artificial sweetener and a modified form of aspartame, typically used as a sugar substitute in many low-sugar and sugar-free foods and drinks. It is around 200 times sweeter than sugar and is often used by those looking to reduce their sugar intake or lose weight. Despite its widespread use, there has been ongoing debate around its potential health effects.
