Update to the List of Permitted Food Enzymes to Enable the Use of Glucanase and Xylanase in Brewers' Mash


Health Canada's Food Directorate completed a detailed safety assessment of a food additive submission seeking approval for the use of the enzymes xylanase and glucanase from Disporotrichum dimorphosporum DXL-1 in brewers’ mash.

Both xylanase and glucanase from Rasamsonia emersonii (previous name: Talaromyces emersonii) are already permitted for use in brewers’ mash. However, D. dimorphosporum DXL-1 has not yet been approved as a source organism for any permitted food enzyme.

The results of Health Canada’s evaluation of available scientific data support the safety and efficacy of xylanase and glucanase from this new source organism when used as requested by the petitioner. Therefore, Health Canada has modified the List of Permitted Food Enzymes, effective August 14, 2015.

The purpose of this communication is to publically announce the Department's decision in this regard and to provide the appropriate contact information for any inquiries or for those wishing to submit any new scientific information relevant to the safety of this food additive.
