Neotame is a sweetener that is synthesized from aspartame and 3,3-dimethylbutyraldehyde . Its sweetness is about 7,000–13,000 times stronger than that of sucrose . Furthermore, a taste-enhancing effect has been shown in various products. Neotame is more stable than aspartame when heated in the neutral pH range. In clinical studies, neotame shows no influence on blood sugar and insulin plasma concentrations and can therefore also be used for dietetic and diabetic food under certain circumstances and taking into account limited dosages. Patients suffering from phenylketonuria also have no negative effects to fear, as neotame is only used in very small quantities due to its high sweetening power. Accordingly, the amounts of phenylalanine released during its hydrolysis are minimal . This sweetener has been approved in Australia and New Zealand since 2001, as well as in the USA and Mexico . Neotame has also been approved in the EU since January 20, 2010 (by Directive 2009/163 / EC). The European Food Safety Authority (EFSA) has assessed the safety of neotame and issued an opinion. The EFSA comes to the conclusion that neotame is safe as a sweetener and flavor enhancer in food. The authority defines the acceptable daily intake ( ADI ) as 0 to 2 milligrams per kilogram of body weight and day. The sweetener has the E number E 961.
