 Summary  
Food additives are regulated in Canada under Marketing Authorizations  (MAs) issued by th e Minister of 
Health and the Food and Drug Regulations  (Regulations) . Approved food additives and their permitted 
conditions of use are set out in the Lists of Permitted Food Additives  that are incorporated by reference in 
the MAs and published on the Canada.ca website. A petitioner can request that Health Canada authorize  a 
new additive , or a new source  or a new condition of use for an already permitt ed food additive , by filing a 
food additive submission with the Department's Food Directorate. Health Canada uses this premarket 
approval process to determine whether the scientific data support the safety of food additives when used 
under specified condit ions in foods sold in Canada.  
Health Canada’s Food Directorate received a food additive submission s eeking authorization  for the use of 
transglutaminase from Streptomyces mobaraensis  M2020197 in various  dairy, fish, grain, meat , poultry , and 
plant -based fo ods. The requested maximum level of use for this  food enzyme is Good Manufacturing 
Practice . Transglutaminase  from  another strain of this source  organism ( S. mobaraensis  S-8112) is already 
permitted for use in Canada in  a number of the food s requested by the petitioner. Prior to this Notice, t he 
source organism, S. mobaraensis  M2020197 , was not a permitted source for any food enzyme in Canada.  
The results of the Food Directorate’s evaluation of available scientific data support the safety  of 
transglutaminase from S. mobaraensis  M2020197 when used  as requested by the petitioner. Therefore, 
Health Canada has modified the  List of Permitted Food Enzymes  to enable  the use transglutaminase from S. 
mobaraensis  M2020197  by adding the  text shown below to the list. For the definition of “Good 
Manufacturing Practice” set out in column 4 as a Maximum Level of Use, see the Marketing Authorization for 
Food Additives That May Be Used as Food Enzymes .

Rationale  
Health Canada’s Food Directorate completed a premarket safety assessment of transglutaminase from S. 
mobaraensis  M2020197 for use as a food  enzyme  in a variety of foods .  The Directorate  considered 
allergenicity, chemistry, microbiology, molecular b iology, nutrition, and toxicology in the assessment. The 
results of the assessment support the safety of  transglutaminase from S. mobaraensis  M2020197 for its 
requested use  and based on technica l information the enzyme is expected to be effective for its intended 
purposes . Therefore, the Department has enabled the requested use of transglutaminase  from S. 
mobaraensis  M2020197 by adding to the List of Permitted Food Enzymes  the new text shown in the above 
table.

 Other Relevant Information  
Food additives such as transglutaminase  are required to meet food -grade specifications set out in Part B of 
the Regulations , where such specifications exist,  or those set out in the  most recent  edition of the  Food 
Chemicals Codex  or th e Combined Compendium of Food Additive Specifications  where there are no 
specifications in Part B .  The Food Chemicals Codex  is a compendium of food grade specifications for food 
ingredients, including food additives, published by the United States Pharmacopeial Convention. 
Specifications in the  Combined Compendium of Food Additive Specifications  and its associated General 
Specifications and Considerations for Enzyme Prepa rations  are prepared by the Joint FAO/WHO Expert 
Committee on Food Additives (JECFA) , both of which are  published by the Food and Agriculture Orga nization 
of the United Nations.  
Implementation and Enforcement  
The above modification s came into force March  2, 2022, the day they were  published in List of Permitted 
Food Enzymes . 
The Canadian Food Inspection Agency is responsible for the enforcement of the Food and Drugs Act and its 
associated regulations with respect to foods.
