A process for deproteinizing milk products, such as milk or whey, is disclosed. In connection with the steps of acidifying and heating the milk product, the milk product is also demineralized at least to some extent prior to the precipitation of the serum proteins. By means of this demineralization, a destabilization of the proteins is attained, allowing these serum proteins to be precipitated by acidification and heating. The milk products may be deproteinized in dependence upon the degree of demineralization, and the amount of serum protein can be reduced to approximately 0.2% or less. Also, partial or complete demineralization of milk proucts permits a lower acid proportion in the product by maintaining acidification at the same pH value. Reduced acidification time is also noted.
