Stakeholder input wanted: survey on research needs for assessing GMO impacts 

Shaping the Future of GMO Research

Stakeholder with interests in the risk and/or benefit assessment of Genetically Modified Organisms (GMO’s) are invited to take part in an online survey.

The aim of this survey is to identify which research needs should be prioritised, thereby contributing to the commissioning of research on the health, environment and economic impacts of GMOs.

The survey will close on 15th July 2015.

E 957 | Sweetener
Possible use of gene technology Labelling
Producible with help of GM microorganisms No



Thaumatin is a protein of an African sweet wood tree (thaumatococcus danielii) with extreme sweetening power (100,000-fold that of cane sugar).

  • Thaumatin is practically calorie free and also suitable for diabetics. It also has a flavour enhancing effect.

Thaumatin can be quickly absorbed by the human body and, by way of urination, can be eliminated unaltered.


Use in calorie reduced or sugar free food. Approved in the EU for calorie free

Gene technology

Traditionally, thaumatin is won from the sweet wood tree.

  • The production with help of genetically modified microorganisms (e.coli-bacteria yeast) now is possible. Presumably, this procedure will be used commercially, but detailed information is not available.

Labelling: additives that are produced in closed systems with help of GM microorganisms are not subject to a labelling requirement, prerequisite being that the respective additive has been purified and does not contain any microorganisms.

Even if the microorganisms obtain nutrients (substrates) derived from GM plants, the additive is not subject to a labelling requirement.
