Revised safety evaluation of the food enzyme glucose oxidase from the genetically modified Trichoderma reesei strain AR-352

The food enzyme glucose oxidase (β-d-glucose: oxygen 1-oxidoreductase; EC 1.1.3.4) is produced with the genetically modified Trichoderma reesei strain AR-352 by AB Enzymes GmbH. In a previous opinion, the Panel on Food Contact Materials, Enzymes and Processing Aids of the European Food Safety Authority could not conclude on the absence of recombinant DNA from the production strain in the food enzyme due to uncertainties about the limit of detection of the applied methodology. New data provided by the applicant showed that no DNA from the production strain was found in the food enzyme with a limit of detection meeting the requirements of the applicable guidance. Based on the new data provided, the Panel concludes that this food enzyme is free from recombinant DNA from the production strain.
