The European Food Safety Authority (EFSA) is calling for scientific data on aspartame (E 951) related to 5-benzyl-3,6-dioxo-2-piperazine acetic acid (DKP) and other primary or secondary degradation products from aspartame. According to EFSA regulations, all food additives permitted before January 20, 2009 are subject to a new risk assessment.
The Scientific Panel on Food Additives and Nutrient Sources added to Food has identified the need for additional data on products that can be formed from aspartame in different types of foodstuffs, in particular DKP—depending on pH, temperature or storage time.
