On 9 June 2026, the European Food Safety Authority (EFSA) published a scientific opinion evaluating the safety of an extension of use of the food enzyme glucan 1,4-α-maltohydrolase produced from a genetically modified Bacillus licheniformis strain NZYM-CY. The opinion concludes that the proposed extension of use does not raise safety concerns under the intended conditions of use, impacting food manufacturers and consumers who may see this enzyme used in a broader range of food processing applications.
The document, a scientific opinion from EFSA's Panel on Food Contact Materials, Enzymes and Processing Aids (CEP), assesses the safety of the enzyme for use in additional food processes beyond those previously evaluated. The enzyme is used to hydrolyse starch into maltose and maltodextrins, and the extension covers its use in the production of glucose syrups and other starch hydrolysates.
EFSA's evaluation follows the applicant's request to expand the enzyme's authorised uses. The opinion is not legally binding but serves as a risk assessment basis for the European Commission and Member States when considering amendments to the Union list of food enzymes under Regulation (EC) No 1332/2008.
Policy orientations and trade-offs
EFSA's favourable opinion supports industry innovation by allowing a broader application of an existing enzyme, potentially reducing production costs and improving efficiency for starch processors. However, the use of a genetically modified microorganism (GMM) may raise consumer concerns about GMOs in food production, even though EFSA found no safety issues. The opinion does not address labelling or consumer acceptance, which remain separate regulatory and market considerations.
Impact on stakeholders
- Food manufacturers (starch processors): Positive impact. The extension allows use of a proven enzyme in more processes, potentially lowering costs and increasing product consistency.
- Consumers: Neutral to positive. No safety concerns identified, but some consumers may object to GMM-derived enzymes on principle.
- EU regulatory bodies: The opinion provides a scientific basis for updating the Union list, streamlining the authorisation process.
- Enzyme producers: Positive impact. The applicant gains a broader market for its product, while competitors may face pressure to seek similar extensions.
Expected institutional follow-up
The European Commission will now consider EFSA's opinion and propose an amendment to Regulation (EU) No 1332/2008 to update the Union list of authorised food enzymes. Member States will vote on the proposal in the Standing Committee on Plants, Animals, Food and Feed. If adopted, the extension will apply across the EU.
