What Is Pea Protein?

Pea protein is a plant protein isolate obtained from yellow peas (Pisum sativum), typically with 80% protein or more. As an alternative to soy and gluten, available non-GMO and with good emulsifying and gelling properties, it has become the fastest-growing plant protein ingredient of the last decade. Its amino acid profile is rich in lysine and limited in methionine.

How is it produced? Isolate versus concentrate

Peas are dehulled and milled; dry fractionation (air classification) yields a 50–55% protein concentrate, wet extraction with isoelectric precipitation an 80–85% protein isolate. In isolate production the protein is solubilised, starch and fibre are removed, the protein is precipitated by pH adjustment, neutralised and spray dried. Concentrate is cheaper and adequate for bakery; isolate delivers the functionality needed for beverages and meat alternatives.

Functional properties

Pea protein binds water and fat, gels on heating, stabilises emulsions and foams. These properties are optimised by grade: beverage grades for high solubility and low flavour, meat-alternative grades for high gel strength and water holding. The typical "green/beany" note varies markedly between suppliers; low-flavour grades cost more.

Applications in food manufacturing

Plant-based burgers, sausages and nuggets; plant-based milk, yoghurt and cheese alternatives; protein shake and beverage powders; protein bars; sports nutrition; gluten-free bakery and pasta; enrichment of instant soups and sauces. Typical usage is 2–20%.

Technical properties and quality criteria

Check protein (≥ 80%, N×6.25, dry basis), moisture (≤ 8%), fat (≤ 8%), ash (≤ 6%), sodium (depends on neutralisation), particle size (100–200 mesh), solubility (at pH 7), gel strength or water-holding capacity, colour, flavour score and microbiological values. Allergen (pea is a legume), non-GMO, halal and organic statements are requested by application.

What to check when buying

Define the application first, then ask for the grade made for it; a "general purpose" isolate can sediment in beverages or give weak texture in meat alternatives. Sample evaluation for taste and solubility is essential. China, Canada and France are common origins. Obtain the specification, lot-specific COA, allergen-GMO statements and halal/organic certificates where needed with the quotation.

Wholesale sourcing: price and minimum order

The wholesale price of pea protein is set by protein content (isolate/concentrate), grade (beverage, meat alternative, standard), flavour level, organic certification, origin and order quantity. The typical minimum order is one pallet (500 kg). PERDIST identifies the grade suited to your application, compares sources and provides a written quotation with documents.

Frequently asked questions

What is the difference between pea protein isolate and concentrate?

Isolate is produced by wet extraction and contains 80% protein or more; concentrate is produced by dry fractionation and contains 50–55%. Isolate is more functional and more expensive.

How can the beany taste of pea protein be reduced?

Choosing a deflavoured grade, using masking flavours such as cocoa or vanilla, and blending with rice protein all reduce the taste noticeably.

Is pea protein an allergen?

Pea is not one of the 14 allergens requiring mandatory declaration in the EU and Türkiye, but reactions have been reported in people with legume allergies. Label "pea protein" clearly.

Documents to request from the supplier

Protein calculation: the nitrogen factor (N×6.25) and whether the value is on dry matter.
Solubility and particle distribution data, plus notes on the taste profile.
Batch certificate of analysis and origin document, showing the number of the batch shipped.

Sample and approval steps

The steps from requesting a sample to the application trial and keeping a reference sample are set out in the ingredient sample evaluation and approval guide.

Regulatory and documentation context

Protein content and wording such as "high protein" fall under nutrition claim rules: the Turkish Food Codex regulation on nutrition and health claims, and Regulation 1924/2006 in the EU. Allergen declaration is required separately for egg and plant proteins.
