摘要

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 precipitate protein therefrom, heating the acidified raw material in a first heating stage to a temperature of about 35-65.degree.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 60-95.degree.C and immediately after reaching the intended temperature, concentrating the precipitated protein and cooling the resulting concentrate.
