The invention relates to a process for dephosphorylation of skim milk, ultra-filtered milk (UF milk) or micellar casein isolate (MCI) comprising (i) acidification of a skim milk, UF milk or MCI preferably not lower than pH 6.0, preferably between 6.0 and 6.7, (ii) cooling the acidified skim milk, UF milk or MCI to the temperature between 0 C. and 15 C., (iii) adding gluconate and/or maleate to the cooled skim milk, UF milk or MCI and, (iv) washing the skim milk, UF milk or MCI, to remove phosphorus, thus dephosphorylating the skim milk, UF milk or MCI, preferably to an extent that the total phosphorous content of the skim milk, UF milk or MCI is reduced with at least 20%, preferably 20-40%, more preferably 30-40% compared to the material provided to step (i). The invention also relates to dephosphorylated MPC, MPI or MCI obtainable by the process of the invention, and to a liquid heat-sterilized enteral nutritional composition comprising 2.0-3.0 kcal/ml wherein 16-35 en % is provided by protein, the combination of caloric content and relative protein caloric content selected such that there is 10-18 g/100 ml protein, preferably 12-18 g/100 ml protein in the composition, wherein the protein comprises micellar casein (MC), whey protein (WP) and optionally caseinate (CAS), wherein there is at least 70 wt % MC and less than 15 wt % WP, based on total protein content, and wherein the composition has a total amount of phosphorous less than 192 mg/100 ml and/or 30-80 mg/100 kcal, preferably at least 30-80 mg/100 kcal, most preferably less than 192 mg/100 ml and 30-80 mg/100 kcal.

A method for producing an ingredient comprising a combination of at least three milk proteins, the method comprising: mixing at least a primary liquid composition, comprising micellar caseins A1, milk serum proteins B1 and denatured milk serum proteins C1, milk serum proteins B1 being different from denatured milk serum proteins C1, said micellar caseins A1, milk serum proteins B1 and denatured milk serum proteins C1 being mixed in liquid form to obtain a mixture; applying at least 50 bars to the mixture; and obtaining the ingredient, wherein: a ratio of the dry mass of micellar caseins A1 to the mass of the total nitrogenous matter (TNM) of the ingredient is greater than or equal to 50%; a ratio of the dry mass of milk serum protein B1 relative to the mass of the solids of the mixture is greater than or equal to 5% and less than or equal to 35%; a ratio of the dry mass of denatured milk serum protein C1 to the mass of the solids of the mixture is greater than or equal to 5% and less than or equal to 45%; a ratio of the dry fat mass to the total dry mass in the ingredient is comprised between 0.2% and 6%. The ingredient. A method of production of a dairy product. The dairy product.
