Pea protein isolate

Pea protein isolate is a concentrated source of protein derived from yellow split peas. The process typically involves dehulling and milling the peas into flour, followed by extraction and purification steps to separate the protein from carbohydrates and fibre. This results in a powder with a high protein content, often exceeding 80%.

Manufacturers add pea protein isolate primarily for its nutritional value as a protein source, particularly in plant-based products. It functions as a protein enhancer in foods like protein powders, bars, and meat analogues, contributing to texture and mouthfeel. It is also used in sandwiches and baked goods to boost protein content.

Pea protein isolate is not classified as a food additive and therefore does not have an E-number. It is a source of dietary protein, which is essential for bodily functions. The UK's Department for Environment, Food & Rural Affairs (Defra) has noted its increasing use in food products. Evidence regarding specific health effects at typical consumption levels is generally positive, relating to protein intake. No major controversies are widely reported regarding its consumption as part of a balanced diet.
