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.
