Aspartame
A low-calorie artificial sweetener made from two amino acids.
i Additive Details
| Uses
Sweetens diet soft drinks, sugar-free chewing gum, sugar-free yogurt, low-calorie desserts, tabletop sweeteners (such as Canderel and NutraSweet), and some medications. About 200 times sweeter than sugar.
| Precautions
People with phenylketonuria (PKU) must avoid aspartame because they cannot metabolize phenylalanine. Products in many markets must carry the warning 'contains a source of phenylalanine'. The WHO's IARC classified aspartame as 'possibly carcinogenic to humans' (Group 2B) in 2023; the FAO/WHO JECFA kept its ADI unchanged that same year.
| Interactions
Breaks down at high temperatures (above about 80 °C), so it is unsuitable for baking. Decomposes in the body to aspartic acid, phenylalanine, and methanol, all of which are present in much larger amounts in many ordinary foods.
| Origin
Synthetic. Produced by chemically joining aspartic acid and phenylalanine (both naturally occurring amino acids) into a methylated dipeptide.
| Daily Intake
EFSA's ADI is 40 mg per kg of body weight per day. The FDA's ADI is 50 mg per kg. The JECFA reaffirmed 40 mg per kg in 2023.
