There is provided a method for the manufacture of a cream cheese, the method comprising: (i) providing cheese curds, (ii) providing a whey protein solution comprising ideal whey, (iii) subjecting the whey protein solution to a cavitation treatment sufficient to heat the whey protein solution to a temperature of at least 70 C. to provide a heat-treated whey protein solution, (iv) mixing the cheese curds and the heat-treated whey protein solution to form a mixture, and (v) subjecting the mixture to a texture-building heat-treatment to form the cream cheese.

Process for preparing lactose-free skimmed, partially skimmed and whole milk, comprising the following steps: 1) pasteurization and skimming, 2) enzymatic hydrolysis of the skimmed milk by lactase enzyme, 3) microfiltration of the hydrolysed skimmed milk and obtainment of a microfiltration retentate (RMF) and of a microfiltration permeate (PMF), 4) PMF ultrafiltration and obtainment of an ultrafiltration retentate (RUF) and of an ultrafiltration permeate (PUF), 5) first PUF nanofiltration and obtainment of the first nanofiltration retentate (RNF 1) and of a first nanofiltration permeate (PNF 1), 6) second PNF 1 nanofiltration and obtainment of a second nanofiltration retentate (RNF2) and of a second nanofiltration permeate (PNF2), and 7) final step: obtainment of lactose-free milk by mixing one or more of the fractions deriving from one or more of the previous steps, which is characterized in that: (I) the first nanofiltration of step 5) is carried out with membranes having a molecular weight cut-off ranging from 400 to 600 Da and the second nanofiltration is carried out with membranes having a molecular weight cut-off ranging from 150 to 250 Da, and (II) the final step 7) is carried out by mixing a composition comprising at least RUF, RNF1 and PNF2.

The disclosure provides a simple and effective methods for sterilization of milk without degradation or loss of biologically active agents in the milk and the products produced by such methods.

The present invention pertains to an improved process for production of nutritional products, such as e.g. infant formulas, containing milk protein and milk saccharide. The invention is par-ticularly useful for the production of demineralized nutritional products and provides both the final nutritional product as well as milk saccharide-containing milk protein serum ingredients useful for the production of such nutritional products.

A method of preparing a low calorie, Lactose-free and Phosphorus-reduced milk with multiple filtration, centrifugation, carbonation and phase separation steps to remove Lactose and Phosphorus from milk including skim milk. The method includes a filtration apparatus to employ ultrafiltration to remove Lactose and any component of Lactose. Ultra-Centrifugation is used additionally to increase and complete the removal of Lactose and to facilitate the reduction of Phosphorous in the final milk preparation. The process eliminates the conventional use of lactase enzyme to hydrolyze Lactose into its simple sugar components.

The invention relates to a method of modification of dry matter composition and/or dry matter content of milk, comprising the steps of: providing raw milk having a fat content in the range of about 3% w/w to about 60% w/w; modifying a dry matter composition and/or dry matter content of the raw milk to provide a modified raw milk having a fat content in the range of about 35% w/w to about 60% w/w based on the total weight of the modified raw milk, and a protein content of at most 3% (w/w) and/or carbohydrate content of at most 4% (w/w) based on a fat-free portion of the modified raw milk. The invention further relates to a method of production of butter, wherein the milk with the modified dry matter composition and/or dry matter content is churned to provide butter.

The invention pertains to a process for simultaneous producing an infant formula product and a dairy product from defatted animal milk, comprising (a) processing the milk into a casein stream, a whey protein stream and a lactose stream by a combination of microfiltration and ultrafiltration, wherein the casein stream originates from the microfiltration as retentate, the whey protein stream originates from the ultrafiltration as retentate and the lactose stream originates from the ultrafiltration as permeate; (b) combining at least part of the whey protein stream originating from step (a) and a lactose source to obtain are combined stream; (c) using the recombined stream originating from step (b) in the manufacture of the infant formula product; and (d) using at least part of the casein stream originating from step (a) and defatted animal milk in the manufacture of the dairy product. The invention further concerns the infant formula product obtainable by step (c) of the process according to the invention, and to the dairy product obtainable by step (d) of the process according to the invention.
