A History of European Regulation for Steviol Glycosides
The journey for steviol glycosides to gain widespread acceptance in Europe was lengthy and involved considerable scientific scrutiny. Before 2011, they were not authorized in the EU due to insufficient safety data, with restrictions placed by the European Commission. Products containing stevia were sometimes marketed for other uses during this period.
A turning point occurred in 2010 when the European Food Safety Authority (EFSA) published a comprehensive safety assessment. Following EFSA's positive opinion, the European Commission formally authorized steviol glycosides as a food additive (sweetener) on November 11, 2011, effective from December 2011. They were assigned the E-number E960. Since this initial approval, the EU has updated its regulations based on new scientific evidence, expanding the range of authorized steviol glycosides and refining manufacturing processes.
E-Numbers and Steviol Glycoside Production Methods
The EU regulates different steviol glycoside production methods under the E960 umbrella.
| Production Method | E-Number | Description | EU Authorization Status | 
|---|---|---|---|
| Water extraction from Stevia leaves | E960a | Traditional method. | Authorized since 2011. | 
| Fermentation using yeast | E960b | Uses genetically modified Yarrowia lipolytica yeast. | Authorized from April 2025. | 
| Enzymatic conversion of leaf extracts | E960c | Enzymes convert extracts into different glycosides. | Several variations authorized since 2021. | 
| Glucosylation | E960d | Adds glucose molecules to extracts. | Authorized since 2023. | 
Why the Ban Rumors Persist
Rumors of a ban often stem from misunderstandings of the EU's complex regulatory process for food additives and the historical restrictions.
- Prior Restrictions: Before 2011, stevia and its extracts were indeed banned in the EU due to the 'novel food' rules requiring extensive safety testing. Awareness of this earlier period can lead to the belief that the ban is still in place.
- Leaf vs. Extract: The EU regulates highly purified steviol glycoside extracts (E960), requiring at least 95% total steviol glycosides. Unpurified crude extracts or the whole Stevia leaf are not authorized as sweeteners in the EU, though the leaf can be used for infusions. The US FDA has similar restrictions on the whole leaf.
- Conflation with other Sweeteners: Sometimes, controversies surrounding other sweeteners are incorrectly associated with steviol glycosides.
Conclusion: A Green Light, with Regulations
Steviol glycosides are not banned in Europe. They have been authorized as a safe food additive (E960) by EFSA and the European Commission since 2011. Their use is widespread and regulated with strict purity standards and maximum permitted levels (MPLs) that vary by food category. While the raw leaf and crude extracts are not approved as sweeteners, the refined extracts are legal and commonly used. The journey from initial ban to approval reflects the rigorous scientific process ensuring food additive safety in the EU.

The E-Number System and Labeling
E-numbers, like E960, indicate an additive has passed EU safety assessments. Labeling rules require foods with sweeteners to state "with sweetener(s)" or "with sugar(s) and sweetener(s)".
- The additive's name and E-number must be listed in ingredients.
- Table-top sweeteners must specify the sweetener, e.g., "...-based table-top sweetener".
This ensures consumer awareness of ingredients like 'E960a: Steviol glycosides from Stevia'.
Maximum Permitted Levels and Applications
The EU sets Maximum Permitted Levels (MPLs) for steviol glycosides in various food and beverage categories to prevent excessive consumption. For example, energy-reduced soft drinks have an MPL of up to 150 mg/L, while chewing gum without added sugar can have up to 3300 mg/kg. The full list of MPLs can be found on the {Link: European Commission Food Additives Database https://ec.europa.eu/food/food-feed-portal/screen/food-additives/search/details/POL-FAD-06121}.
Safety and Scientific Consensus
Major scientific bodies globally, including the Joint FAO/WHO Expert Committee on Food Additives (JECFA), support the safety of steviol glycosides, aligning with the EU's ADI of 4 mg/kg body weight/day. Authorized preparations have been extensively tested and show no genotoxic, carcinogenic, or adverse reproductive effects. This scientific backing supports authorizations in Europe and other markets.
