Safety evaluation of the food enzyme β‐glucosidase from the genetically modified Trichoderma reesei strain DP‐Nyk114

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The food enzyme β‐glucosidase (β‐d‐glucoside glucohydrolase; EC 3.2.1.21) is produced with the genetically modified Trichoderma reesei strain DP‐Nyk114 by Genencor International B.V. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. It is

Safety evaluation of the food enzyme glucan 1,4‐α‐glucosidase from the non‐genetically modified Aspergillus niger strain AE‐GN

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The food enzyme glucan 1,4‐α‐glucosidase (4‐α‐d‐glucan α‐glucohydrolase; EC 3.2.1.3) is produced with the non‐genetically modified Aspergillus niger strain AE‐GN by Amano Enzyme Inc. The food enzyme was considered free from viable cells of the production organism. It is intended to be used in 13 food manufacturing processes.

Safety evaluation of a food enzyme containing oryzin and leucyl aminopeptidase activities and a heat‐treated food enzyme containing only leucyl aminopeptidase activity from the non‐genetically modified Aspergillus sp. strain FL 72‐230

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract This assessment addressed two food enzymes produced with the non‐genetically modified microorganism Aspergillus sp. strain FL 72‐230 by Shin Nihon Chemical Co., Ltd. The native food enzyme contains leucyl aminopeptidase (EC 3.4.11.1) and oryzin (EC 3.4.21.63) activities.

Revised safety evaluation of the food enzyme catalase from the non‐genetically modified Aspergillus niger strain CTS2093

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The food enzyme catalase (hydrogen‐peroxide:hydrogen‐peroxide oxidoreductase; EC 1.11.1.6) is produced with the non‐genetically modified Aspergillus niger strain CTS2093 by Shin Nihon Chemical Co., Ltd. In a previous evaluation, the Panel could not exclude safety concerns due to an insufficient margin of exposure (MoE).
