Beschreibung
Zusammenfassung:	A method for preparing a protein concentrate useful in the production of a low calorie margarine of water-in-oil type which comprises acidifying a raw material comprising skimmed milk, skim milk powder or a mixture thereof to a pH of 4-5 to precipitate protein therefrom, heating the acidified raw material in a first heating stage to a temperature of about 35 DEG -65 DEG C. and maintaining said temperature for a period of at least 15 minutes, then quickly raising the temperature of the acidified milk in a second heating stage to a temperature of about 60 DEG -95 DEG C. and immediately after reaching the intended temperature, concentrating the precipitated protein and cooling the resulting concentrate.
