ABSTRACT:
The invention is concerned with a process for producing an .alpha.-lactalbumin-enhanced fraction from a liquid containing whey protein including .alpha.-lactalbumin and .beta.-lactoglobulin which comprises subjecting said liquid to ultrafiltration using a membrane having a molecular weight cut off of essentially 100,000 to form a permeate having a protein content in which the proportion of .alpha.-lactalbumin is enhanced relative to the proportion obtaining in the protein content of said liquid.
