1. A process for isolating phospholipids from a milk byproduct, the process comprising:
a) filtering the milk byproduct;
b) exposing the milk byproduct to ultrafiltration and/or diafiltration;
c) exposing a retentate obtained from ultrafiltered milk byproduct of step b) to centrifugation;
d) exposing a precipitate obtained after centrifugation of step c) to chemical solubilization; and
e) solubilizing and removing proteins and caseins; thereby isolating phospholipids from the milk byproduct.
