Safety evaluation of the food enzyme β-galactosidase from the genetically modified Bacillus licheniformis strain NZYM-BT.

ABSTRACT: The food enzyme β-galactosidase (β-d-galactoside galactohydrolase; EC 3.2.1.23) is produced with the genetically modified Bacillus licheniformis strain NZYM-BT by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The production strain has been shown to qualify for the qualified presumption of safety (QPS) status. The food enzyme was considered free from viable cells of the production organism and its DNA. It is intended to be used in milk processing for the hydrolysis of lactose. Based on the assumption that all selected milk and milk products are enzymatically treated, dietary exposure to the food enzyme-total organic solids (TOS) was estimated to be up to 0.34 mg TOS/kg body weight (bw) per day in European populations. Toxicological data were reported a
