A method for the manufacture of margarine of the water-in-oil type having a low calorie value and a high content of proteins by emulsifying a water phase containing 20-24% proteins into a fat phase composed of oil and/or fats, at a temperature of about 38 DEG -55 DEG C. to provide a water-in-oil emulsion, comprised of about 35-65% fat phase and 65-35% water phase in which water phase is produced from a raw material comprising skimmed milk, skim milk powder or a mixture thereof by acidifying the raw material to a pH of 4-5 to precipitate protein therefrom, heating the acidified raw material and any admixtures 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 raw material in a second heating stage to a temperature of about 60 DEG -95 DEG C. and immediately after reaching the intended temperature, separating the precipitated protein and cooling the separated protein to at least the emulsification temperature and emulsifying the water phase thereby obtained in the fat phase to directly form the water-in-oil emulsion. |
