Abstract: A method of producing rennet cheese from raw milk, wherein raw milk is standardized, a biological reaction is terminated, a precipitant and cultures are added, cheese mass is separated from whey, and denatured cheese fines are removed from the whey by separation or decantation. The cheese fines are biologically acidified in whey or water, the denatured proteins are removed from the whey or water, the denatured proteins are removed from the whey by separation or decantation, whereby the major proportion of the detrimental calcium is removed along with the separated liquid, the fines are suspended in water or whey, the suspension is warmed for 5 to 10 minutes at 40.degree. to 60.degree. C., the pH is adjusted to form 6.5 to 7.0 and with a 10% neutralization agent, the material is heated to from 80.degree. to 90.degree. C. for 1 to 5 minutes, and the product is returned to the raw milk or added to other dairy products to increase the protein content or the proportion of dry mass.

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.
