Modification to the List of Permitted Food Enzymes (cellulase)
Notice of Modification – Lists of Permitted Food Additives
Reference number: MFAA-2616
November 10, 2026
Summary
The purpose of this notice is to announce that Health Canada modified the List of Permitted Food Enzymes to authorize the use of cellulase from Trichoderma reesei strain AR-852 as a food enzyme in bread, white flour, whole wheat flour, brewers' mash, malt extract and unstandardized bakery products at a maximum level of use of "Good Manufacturing Practice" (GMP) Footnote 1, as shown in Table 1.
This modification comes into force on November 10, 2026.
Background
The food additives authorized for use in Canada are set out in the Lists of Permitted Food Additives. These lists are incorporated by reference into Division 16 of the Food and Drug Regulations.
A person, company or organization (referred to as the petitioner) may ask Health Canada to authorize a new food additive use by filing a food additive submission.
Issue
Health Canada received a food additive submission requesting that cellulase from T. reesei AR-852 be authorized for use as a food enzyme at a maximum level of use of GMP in the following foods:
- Bread
- White flour
- Whole wheat flour
- Brewers' mash
- Malt extract
- Unstandardized flours, unstandardized dry mixes such as cake mix, brownie mix, muffin mix, pancake mix, waffle mix, cookie mix, scone mix, and biscuit mix, and unstandardized bakery products (all of which fall within "Unstandardized bakery products" in the Lists of Permitted Food Additives).
At the time the request was filed, cellulase from several other sources was already authorized for use in the requested foods. However, the AR-852 strain of T. reesei was not an authorized source for any food enzyme in Canada.
Rationale
Health Canada completed a premarket assessment of cellulase from T. reesei AR-852 for its requested use. The assessment considered potential dietary exposure to cellulase from T. reesei AR-852, and other food safety aspects (allergenicity, chemistry, microbiology, molecular biology, nutrition, and toxicology).
The outcome of Health Canada's assessment supports authorizing the use of cellulase from T. reesei AR-852, as set out in Table 1.
Modification to the list
Health Canada has authorized the requested use of cellulase from T. reesei AR-852 by adding the new subitem C.4.(6) and its corresponding paragraphs (a) to (d) to the List of Permitted Food Enzymes, as shown in Table 1.

- Footnote 1
-
When the words "Good Manufacturing Practice" appear in column 5 of the Lists of Permitted Food Additives, it means that the amount of the food additive in, on or added to the food does not exceed the amount required to accomplish the purpose for which it is added.
- Footnote 2
-
The Food Chemicals Codex is published by the United States Pharmacopeial Convention.
- Footnote 3
-
The Combined Compendium of Food Additive Specifications and its associated General Specifications and Considerations for Enzymes Used in Food Processing are prepared by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and published by the Food and Agriculture Organization of the United Nations.
