Pea protein isolation is the process of extracting and purifying protein from peas, specifically the protein-rich component of the pea plant known as pea protein. Pea protein has gained popularity as a plant-based protein source due to its nutritional profile, allergen-free nature, and sustainable cultivation practices associated with peas.

The isolation process typically involves milling dried peas to create a pea flour, followed by a series of steps to separate the protein from other components such as carbohydrates and fibers. Common methods include wet extraction using water or mild solvents, followed by precipitation, filtration, and drying to obtain a concentrated pea protein powder.
