Vital wheat gluten

Vital wheat gluten suppliers and sourcing guide

Vital wheat gluten is the main protein of wheat, made of gliadin and glutenin. Wheat flour is mixed with water into a dough and washed so the starch separates from the elastic gluten mass, which is then dried gently (usually flash or ring dried) so it keeps its ability to form dough again. The powder is about 75 to 80% protein and is used to strengthen bread doughs, bind meat analogs such as seitan, and add protein to baked goods.

Forms and grades of vital wheat gluten

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

  • Vital wheat gluten

    Gently dried gluten that keeps its elasticity; the standard grade for baking and meat analogs.

  • Hydrolyzed wheat protein

    Gluten partly broken down by enzymes or acid for solubility; it loses dough-forming properties.

  • Textured wheat protein

    Extruded gluten pieces for meat analogs.

  • Organic

    Made from certified organic wheat flour.

What to check on the COA

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

Protein (Kjeldahl or Dumas)
Total nitrogen times 5.7 (the usual factor for wheat), on an as-is and dry basis.
Moisture, fat and ash
Proximate analysis; moisture is usually held below about 8%.
Water absorption and vitality
Water absorption and a gluten index or dough test to confirm the gluten is still vital.
Microbiology
Total plate count, coliforms, yeast and mold, Salmonella and E. coli.
Mycotoxins
Deoxynivalenol (DON) and other wheat mycotoxins by LC-MS/MS or ELISA.

Storage, lots and expiry

Storage and shelf life

Store sealed, cool and dry, and protect from pests. Heat and humidity reduce vitality over time, so warm storage shortens usable life. Shelf life comes from the supplier's specification, with a retest of vitality and moisture for older stock.

Lots and expiry dates

Record protein and water absorption for each lot, since these change how much water a dough needs. Wheat gluten is a major allergen, so keep it segregated and labeled in shared facilities.

Regulatory status

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

Frequently asked questions

What forms of vital wheat gluten can brands buy?

Common forms include vital wheat gluten, hydrolyzed wheat protein, textured wheat protein and organic. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for vital wheat gluten include?

Expect protein (Kjeldahl or Dumas), moisture, fat and ash, water absorption and vitality, microbiology and mycotoxins, each with its method, specification and result for that lot.

How should vital wheat gluten be stored?

Store sealed, cool and dry, and protect from pests. Heat and humidity reduce vitality over time, so warm storage shortens usable life. Shelf life comes from the supplier's specification, with a retest of vitality and moisture for older stock.
