Abstract
Methods of making food-grade plant protein compositions, including yellow pea protein compositions, are provided. The methods use pulses, such as yellow peas, and flours derived therefrom.
Claims20
A method for making a plant 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;
- (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;
- and
- (d) removing water from the protein-rich retentate to provide a dry plant protein composition having a pulse protein concentration of at least 70%, based on a dry weight basis.
