Canola protein

Canola protein suppliers and sourcing guide

Canola protein is extracted from canola (low-erucic rapeseed, Brassica napus and related species) meal or press cake left after the oil is removed. Processes use water or mild salt extraction followed by membrane filtration or precipitation, which separates the two main proteins, cruciferin and napin, from fiber and from bitter compounds such as glucosinolates and phenolics. Brands buy isolates or concentrates for drinks, bars, dairy alternatives and meat alternatives.

Forms and grades of canola protein

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

Protein isolate
About 90% protein or more on a dry basis; some suppliers sell cruciferin-rich and napin-rich isolates separately because they behave differently in foods.
Hydrolyzed isolate
Isolate partly broken down with enzymes for higher solubility in drinks.
Protein concentrate
Lower-protein material that keeps more of the fiber, used in bakery, cereals and snacks.
Non-GMO grades
Material from identity-preserved non-GMO canola; most North American canola is genetically engineered, so ask for documentation.

What to check on the COA

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

Protein: Crude protein by Dumas combustion or Kjeldahl (N x 6.25), on an as-is and dry basis; this is the main number you pay for in canola protein.
Moisture and ash: Moisture by loss on drying and total ash, which together with protein and fat close the proximate analysis.
Fat, fiber and carbohydrate: Fat and dietary fiber by AOAC methods for the nutrition panel; residual fat also affects flavor stability.
Heavy metals: Lead, arsenic, cadmium and mercury by ICP-MS; plant proteins concentrate metals from the seed, so check results against your own limits.
Microbiology: Total plate count, yeast and mold, Enterobacteriaceae or coliforms, E. coli and Salmonella.
Glucosinolates and phenolics: Residual glucosinolates and phenolic compounds by HPLC, which affect taste and color and show how well the process removed them.

Storage, lots and expiry

Storage and shelf life

Store canola protein sealed in its multiwall bag or lined container in a cool, dry place away from strong odors, and reseal opened packs, since the powder picks up moisture and odors. Warm storage speeds off-flavor development from residual fat. Shelf life is set by the supplier's specification, and moisture, micro and a taste check are the usual retest points.

Lots and expiry dates

Record protein, moisture and color for each lot, and note the protein fraction (cruciferin-rich, napin-rich or mixed) since functionality changes with it. Rotate stock FEFO.
