Pea Protein

Pea Protein suppliers and sourcing guide

Pea protein is extracted from dried yellow field peas (Pisum sativum). For isolates, dehulled peas are milled, the protein is dissolved in water, separated from starch and fiber, precipitated near its isoelectric point, neutralized and spray-dried, giving roughly 80-90% protein on a dry basis. Lower-protein concentrates can also be made by dry milling and air classification, and pea starch and fiber are sold as co-products.

Forms and grades of pea protein

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

  • Pea protein isolate

    Wet-extracted protein at roughly 80-90% protein on a dry basis. The main grade for shakes, bars and plant-based dairy alternatives.

  • Pea protein concentrate

    Lower-protein material, often made by dry fractionation, used where cost matters more than protein density.

  • Soluble or hydrolyzed pea protein

    Grades treated for better solubility and smoother texture in beverages; some are lightly hydrolyzed with enzymes.

  • Textured pea protein

    Extruded pea protein, dry or high-moisture, used as a meat-like base in plant-based foods.

  • Organic and non-GMO

    Isolates from certified organic or non-GMO verified peas, with certificates supplied per lot or per facility.

  • Low-sodium grades

    Isolates with reduced sodium from the neutralization step, for formulas with tight sodium targets.

What to check on the COA

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

Protein content
Protein by Kjeldahl or Dumas (nitrogen x 6.25), as-is and dry basis. Drives the label protein statement and the price per kg of protein.
Composition: moisture, ash, fat and sodium
Sodium comes largely from neutralization during processing and needs to be known for the nutrition panel.
Heavy metals
Lead, arsenic, cadmium and mercury by ICP-MS. Plant proteins are closely watched for lead and cadmium, and results feed Prop 65 and retailer reviews.
Microbiology
Total plate count, yeast and mold, coliforms or E. coli and Salmonella; some buyers add Bacillus cereus.
Pesticide residues
Multi-residue screen, often including glyphosate, especially for non-GMO or organic claims.
Allergen cross-contact
Gluten and soy testing where the finished product makes free-from claims, since peas are often handled alongside grains and soy.
Physical and sensory
Particle size, color, solubility and a flavor check, because beany or earthy notes vary between lots and suppliers.

Storage, lots and expiry

Storage and shelf life

Store sealed in a cool, dry place away from odors. Pea protein is fairly stable as a powder but absorbs moisture, and residual fat can oxidize into beany or cardboard-like off-flavors over time. Shelf life and retest dates come from the supplier's specification.

Lots and expiry dates

Protein, sodium and flavor vary between lots and crop years, so run a taste check of each new lot in the finished formula and recalculate protein per serving from its COA. Keep each lot's heavy-metal results on file for retailer and Prop 65 reviews. Use FEFO.

Frequently asked questions

What forms of pea protein can brands buy?

Common forms include pea protein isolate, pea protein concentrate, soluble or hydrolyzed pea protein, textured pea protein, organic and non-GMO and low-sodium grades. Ask each supplier for the specification sheet of the exact grade they quote.

What should the COA for pea protein include?

Expect protein content, composition: moisture, ash, fat and sodium, heavy metals, microbiology, pesticide residues, allergen cross-contact and physical and sensory, each with its method, specification and result for that lot.

How should pea protein be stored?

Store sealed in a cool, dry place away from odors. Pea protein is fairly stable as a powder but absorbs moisture, and residual fat can oxidize into beany or cardboard-like off-flavors over time. Shelf life and retest dates come from the supplier's specification.

What is the regulatory status of pea protein?

FDA GRAS Notice GRN 608 (Axiom Foods and SPRIM, pea protein concentrate for use as an ingredient, formulation aid and texturizer in foods) closed on May 27, 2016 with a "no questions" letter. FDA GRAS Notice GRN 803 (Ingredion and Shandong Jianyuan Bioengineering, pea protein) closed in November 2019 with a "no questions" letter for several technical uses in conventional foods.
