Aspartame

Products

Aspartame is found in numerous products. It is available as a pure substance in specialized stores. Aspartame was accidentally discovered by James M. Schlatter at Searle in 1965.

Structure and properties

Aspartame (C14H18N2O5, Mr = 294.3 g/mol) exists as a white, crystalline, odorless, and slightly hygroscopic powder that is sparingly soluble in water (10 g/liter). It is a methyl ester of a dipeptide composed of L-phenylalanine and L-aspartic acid. Aspartame is a synthetic molecule, but both amino acids are natural and occur in the human body and in foods.

Effects

Aspartame has a sweet taste. It is up to 200 times sweeter than regular table sugar and is virtually calorie-free in the amounts used. Unlike other sweeteners, it is not heat resistant at high temperatures and therefore not suitable for baking.

Areas of application

As a sweetener, including for food, beverages, pharmaceuticals and dietary supplements.

Contraindications

Aspartame should not be taken if you have phenylketonuria or hypersensitivity.

Adverse effects

Aspartame has been used for decades in numerous countries and is considered safe and tolerable by authorities. However, its safety has been the subject of debate for years. No other artificial sweetener has come under more criticism than aspartame.
