The European Food Safety Authority (EFSA) has published a scientific opinion evaluating the safety of the food enzyme subtilisin produced from the genetically modified Bacillus licheniformis strain NZYM-PD. The opinion, released on 8 June 2026, concludes that the enzyme does not raise safety concerns under the intended conditions of use, impacting food manufacturers and consumers relying on enzyme-assisted processing.
The document, a scientific opinion from EFSA's Panel on Food Contact Materials, Enzymes and Processing Aids (CEP), assesses the enzyme's production, composition, and potential toxicity. Subtilisin is a protease used in food processing to hydrolyze proteins, for example in baking, brewing, and dairy production. The evaluation is based on data provided by the applicant and follows EFSA's guidelines for food enzyme safety assessments.
EFSA's opinion is non-binding but serves as a key reference for the European Commission and Member States when deciding on market authorization. The assessment covers potential allergenicity, genotoxicity, and dietary exposure. The panel found no evidence of adverse effects at the proposed use levels, though it noted that the enzyme is produced by a genetically modified microorganism, which requires compliance with EU regulations on GMOs.
Trade-offs and stakeholder impact For food industry operators, the positive safety opinion supports continued or expanded use of the enzyme, which can improve processing efficiency and product consistency. For consumers, the opinion provides reassurance on safety, though some may have concerns about the use of genetically modified organisms in food production. For regulatory authorities, the opinion offers a scientific basis for authorization decisions, balancing innovation with consumer protection. Environmental groups may question the long-term implications of GMO-derived enzymes, though EFSA's assessment focuses on the final product rather than the production strain.
Institutional follow-up The European Commission will now consider EFSA's opinion in its decision on whether to authorize the enzyme for the EU market. Member States will vote on the proposal in the Standing Committee on Plants, Animals, Food and Feed. If approved, the enzyme will be added to the Union list of authorized food enzymes.
