What it is
Aspartame (E951) is a dipeptide methyl ester made from aspartic acid and phenylalanine. It is about 200 times as sweet as sugar, so it is used at very low levels. The assay range on this page is the usual specification range for food-grade aspartame.
Labelling: phenylalanine
Because aspartame releases phenylalanine when digested, products containing it generally need a label statement for people with phenylketonuria (PKU). The exact wording is set by each market’s labelling rules.
Stability
Aspartame is stable as a dry powder but slowly breaks down in water, faster at high temperatures and outside its most stable pH range (around pH 4–5). Breakdown produces diketopiperazine and other compounds and causes a loss of sweetness. It is therefore less suited to baked goods and long-life neutral drinks. Blends with other sweeteners, such as Sucralose or Stevioside, are common.
Safety reviews
Aspartame has been reviewed many times. In 2023 the IARC classified it as “possibly carcinogenic to humans” (Group 2B), a hazard rating, while the joint FAO/WHO expert committee (JECFA) kept its acceptable daily intake of 40 mg/kg body weight. Brands should follow the current position of the regulator in each market.
What the research says
- A 2025 review of 100 controlled experiments found little to no effect of aspartame on blood glucose or insulin, short or long term. Certainty was very low. [1]
- Compared with sugars and other carbohydrates, aspartame gave lower blood glucose and insulin responses. [1]
- The International Agency for Research on Cancer has classified aspartame as possibly carcinogenic to humans. [2]
- A 2023 systematic assessment concluded that aspartame is not carcinogenic in humans. All its authors work for ToxStrategies, a private toxicology company. [3]
