Cellulase

Cellulase suppliers and sourcing guide

Cellulase is an enzyme, usually a mixture of related enzymes, that breaks down cellulose, the main structural fiber of plant cell walls. It is made by fermenting molds such as Trichoderma reesei (also called T. longibrachiatum) or Aspergillus niger, then filtering out the organism and concentrating the enzyme. It is used in juice, extraction and brewing processes and as a powder in supplement enzyme blends.

Forms and grades of cellulase

Suppliers sell different products under the same name. Specify the one you need.

  • Powder on carrier

    Cellulase standardized in FCC cellulase units (CU) per gram on maltodextrin or similar for capsules and dry blends.

  • Liquid concentrate

    Stabilized liquid for fruit, vegetable and botanical extraction, juice and brewing processes.

  • Multi-activity complexes

    Products that combine cellulase with hemicellulase, xylanase or pectinase for plant cell-wall breakdown.

  • Non-GMO grades

    Cellulase from non-genetically modified strains, with documentation for non-GMO programs.

What to check on the COA

Compare each result with your own specification when the lot arrives.

Cellulase activity
Activity by the FCC cellulase method (carboxymethylcellulose viscosity) or a stated method, in units per gram.
Production strain
Source organism, genetic modification status and absence of viable production organism.
Side activities
Other carbohydrase activities (xylanase, beta-glucanase, pectinase) that define the complex.
Heavy metals
Lead (and often arsenic, cadmium and mercury) by ICP-MS, reported against FCC enzyme-preparation limits or the supplier's specification.
Microbiology
Total plate count, coliforms, E. coli and Salmonella, reported against the Food Chemicals Codex (FCC) general limits for enzyme preparations or the supplier's tighter specification.
Loss on drying
Moisture for powders by loss on drying; enzyme activity holds up better in dry product, so moisture above spec is a warning sign for activity loss in storage.

Storage, lots and expiry

Storage and shelf life

Enzyme powders lose activity with heat and moisture, so keep them sealed in the original lined container in a cool, dry place, and refrigerate liquid preparations if the supplier says to. Shelf life is set by each supplier's specification, usually as a guaranteed minimum activity to a stated date, and older stock is retested for activity before use. Supplier safety data sheets for enzyme powders call for dust control and respiratory protection when weighing and blending.

Lots and expiry dates

Record the measured activity per gram for each lot and dose by activity, not weight. Note the production organism and carrier, and rotate stock first-expired, first-out.

Regulatory status

Facts from regulators and standards bodies, each linked to its source.

This is general information, not regulatory advice. Status differs by country and by how the ingredient is used, so check the rules for your product and market.

Frequently asked questions

What forms of cellulase can brands buy?

Common forms include powder on carrier, liquid concentrate, multi-activity complexes and non-GMO grades. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for cellulase include?

Expect cellulase activity, production strain, side activities, heavy metals, microbiology and loss on drying, each with its method, specification and result for that lot.

How should cellulase be stored?

Enzyme powders lose activity with heat and moisture, so keep them sealed in the original lined container in a cool, dry place, and refrigerate liquid preparations if the supplier says to. Shelf life is set by each supplier's specification, usually as a guaranteed minimum activity to a stated date, and older stock is retested for activity before use. Supplier safety data sheets for enzyme powders call for dust control and respiratory protection when weighing and blending.

What is the regulatory status of cellulase?

21 CFR 184.1250 affirms cellulase enzyme preparation from Trichoderma longibrachiatum as GRAS, used in food as an enzyme for the breakdown of cellulose. 21 CFR 173.120 permits carbohydrase and cellulase from Aspergillus niger only in clam and shrimp processing. Health Canada's List of Permitted Food Enzymes includes cellulase (item C.4), with Aspergillus niger among its sources. Health Canada's Digestive Enzymes natural health product monograph lists cellulase with Aspergillus and Trichoderma species as source material.
