Abstract
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.degree.-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.degree.-95.degree. C. and immediately after reaching the intended temperature, concentrating the precipitated protein and cooling the resulting concentrate.
Claims9
A method for the production of a protein concentrate useful in the production of margarine having a low calorie content and a high content of proteins which comprises:
- acidifying a raw material selected from the group consisting of skimmed milk, an aqueous solution of skim milk powder and a mixture thereof to a pH of 4-5 to precipitate proteins therefrom, said proteins comprising casein and whey proteins,
- raising the acidified raw material including said precipitated proteins to a temperature of about 35.degree.-65.degree. C. and maintaining said temperature in a first heating stage for a period of at least 15 minutes depending upon the particular temperature employed, thereby conditioning the precipitated proteins,
- quickly raising the temperature of the acidified and conditioned raw material including said precipitated proteins in a second heating stage at least 10.degree. C. to a temperature of about 60.degree.-95.degree. C. to inactivate bacteria and enzymes,
- immediately after reaching the intended higher temperature, concentrating the precipitated proteins to provide a liquid protein concentrate comprising both casein and whey proteins and
- cooling the resulting liquid protein concentrate, to storing temperature.
