1. A method for making a pulse protein composition, the method comprising:
(a) providing an aqueous slurry comprising hydrolyzed water-soluble and water-insoluble pulse proteins;
(b) removing the water-insoluble pulse proteins and other water-insoluble components from the aqueous slurry to provide a water-soluble, protein-rich liquid fraction comprising both hydrolyzed globulin proteins and hydrolyzed albumin proteins; and
(c) separating water-soluble pulse proteins in the protein-rich liquid fraction from water-soluble lower molecular weight peptides and water-soluble non-proteins in the protein-rich liquid fraction via ultrafiltration using an ultrafiltration membrane that concentrates hydrolyzed globulin proteins and hydrolyzed albumin proteins in a protein-rich retentate having a pulse protein concentration of at least 70%, based on a dry weight basis.
