Abstract
A method of dephospholipidating whey to separate the lipoproteins out of it and/or decrease its residual fat content by adding calcium to the whey, heating it and keeping it hot to aggregate the lipoproteins, and then centrifuging it. The pH of the whey is increased before it is heated by adding sodium-hydroxide solution, and the calcium is not added until after the whey is heated.
Claims7
A method of dephospholipidating whey comprising the steps of:
- aggregating lipoproteins by initially adjusting the pH of whey with continuously added sodium-hydroxide solution, heating the adjusted pH whey to at least 50.degree. C., adding from 0.18 to 0.61 grams of calcium per liter of whey the heated whey, and keeping the whey hot for no longer than 3 minutes;
- and thereafter immediately centrifuging the hot whey to separate the lipoproteins.
