Claim 10:
11. A method for providing a protein isolate powder from egg albumen comprising:
a) removing greater than or equal to 25% by volume of water from the egg albumen to provide an albumen concentrate having a protein content of greater than or equal to 20% by mass;
b) diafiltering the albumen concentrate with purified water until the filtrate exhibits an electrical conductance of less than or equal to 5 millisiemens (mS);
c) collecting retentate from the diafiltering step to provide a protein-rich composition comprising, on a dry basis, less than 0.5% by mass lipids; and
d) spray drying the protein-rich composition to provide the protein isolate powder,
wherein the albumen concentrate and the protein-rich composition are not pH-adjusted prior to spray drying to provide the protein isolate powder.
