A casein isolate which is substantially dispersible in water is disclosed along with the method of isolating this dispersible casein from skim milk. To isolate the casein, skim milk is filtered through a membrane of a type through which casein generally does not pass to concentrate the retentate to about a 4X VCR concentration. The retentate is stored at a temperature below the freezing point of the retentate for about four days. The retentate is diluted with a suitable diluent, such as water, in an amount sufficient to prevent gelling of the retentate. The casein is then substantially separated from the diluent and other materials in the retentate. Normally, this separation is performed by centrifugation.

A method for processing milk to isolate substantially all of the native casein therefrom in a form capable of forming a stable suspension in water, which comprises the steps of filtering milk through a membrane which substantially completely retains native casein while generally allowing lactose and water to pass through, withdrawing the retentate, storing the retentate at a temperature below the freezing point thereof, thawing the retentate, and separating the native casein therefrom in the presence of added water.
