6. Description of content: Health Canada's Food Directorate completed a detailed safety 
assessment of a food additive submission s eeking 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  (http://www.hc-sc.gc.ca/fn-an/secu rit/addit/list/5- enzymes-eng.php ), 
effective 14 August 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. 
Health Canada's Food Directorate is committed to reviewing any new scientific 
information on the safety in use of any food additive, including glucanase and xylanase obtained from D. dimorphosporum  DXL-1. Anyone wishing to submit new scientific 
information on the use of this food additive or to submit any inquiries may do so in 
writing, by regular mail or electronically. G/SPS/N/CAN/949
