主权项

1. A method for removing fat from whey protein concentrate to produce a defatted solids fraction comprising whey protein, the method comprising the steps of
(a) agglomerating particles of whey protein concentrate to produce whey protein agglomerates that readily submerge when admixed with ethanol; (b) admixing the whey protein agglomerates with ethanol in a ratio of from about 1:3 to about 1:5 to immerse the whey protein agglomerates in ethanol for a period of at least about 30 minutes; and (d) separating the defatted solids from the ethanol to collect a defatted solids fraction.
