Safety evaluation of the food enzyme α‐amylase from the genetically modified Bacillus licheniformis strain NZYM‐AY

The food enzyme α‐amylase (4‐α‐d‐glucan glucanhydrolase; EC 3.2.1.1) is produced with the genetically modified Bacillus licheniformis strain NZYM‐AY by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme is considered free from viable cells of the production organism and its DNA. It is intended to be used in starch processing for the production of glucose syrup and other starch hydrolysates, and distilled alcohol production. Since residual amounts of total organic solids are removed by distillation and by the purification steps applied during the production of glucose syrups, dietary exposure estimation was considered unnecessary. The production strain of the food enzyme fulfils the requirements for the qualified presumption of safety (QPS) approach to safety assessment. As no other concerns arising from the manufacturing process have been identified, the Panel considers that toxicological tests are not needed for the assessment of this food enzyme. A search for similarity of the amino acid sequence of the food enzyme to known allergens was made and one match was found. The Panel considered that, under the intended conditions of use (other than distilled alcohol production) the risk of allergic sensitisation and elicitation reactions by dietary exposure cannot be excluded, but the likelihood for this to occur is considered to be low. Based on the data provided, the Panel concluded that this food enzyme did not give rise to safety concerns under the intended conditions of use.
