Disclosed are methods for preparing dairy compositions using a final nanofiltration step. Generally, the methods also include an ultrafiltration step and a reverse osmosis step, and optionally, a diafiltration step.

This disclosure features human milk permeates and compositions containing the same obtained from fractionated whole human milk. The oligosaccharide rich permeate and permeate compositions of the present invention are useful as nutritional supplements for pre-term and full term infants, for establishing or maintaining gut flora and for treating the symptoms of inflammatory bowel disease.

The present invention relates to a method (200) for producing a heat-treated concentrated dairy product (cdp). The method (200) comprising the steps of passing (210) the dairy product (dp) under a pre-determined pressure through a reverse osmosis, RO, filter (110) at a first temperature, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product (dp). Preheating (230) the concentrated dairy product (dp) at a second temperature for a second period of time to stabilize the concentrated dairy product (dp). Homogenizing (240) the stabilized concentrated dairy product (dp) to reduce a size of particles in the stabilized concentrated dairy product (dp). Heating (250) the stabilized concentrated dairy product (dp) at a third temperature for a third period of time to reduce microorganisms in the stabilized concentrated dairy product (dp), thereby forming the heat-treated concentrated dairy product (cdp).

Disclosed are methods for preparing aseptic dairy compositions having at least 35 wt. % solids, and often from 40 to 50 wt. % solids, by subjecting a dairy product to forward osmosis following by a heat treatment step. The heat treatment step can include UHT sterilization via direct steam injection or direct steam infusion. Subsequently, the aseptic dairy composition can be dried to form a dairy powder composition.

The invention relates to a milk-based formulation with a reduced carbohydrate content, having a ratio of carbohydrates to protein of at most 1.1, a protein content of at least 5.4% on dry matter basis, and a ratio of ash to protein is substantially similar to that of a milk raw material used as a starting material, and a method for the preparation thereof. The milk-based formulation can be used in the preparation of a recombined milk product with a reduced lactose content, having a full taste of normal milk without any deficiencies in its organoleptic properties.

A concentration method and equipment. The concentration method includes the step of performing reverse osmosis concentration processing on raw milk by using a reverse osmosis membrane. The reverse osmosis concentration processing includes low-pressure reverse osmosis membrane concentration processing and high-pressure reverse osmosis membrane concentration processing, wherein in the low-pressure reverse osmosis membrane concentration processing, reverse osmosis concentration processing is performed on feeding materials by using a first predetermined pressure, and in the high-pressure reverse osmosis membrane concentration processing, the reverse osmosis concentration processing is performed on the feeding materials by using a second predetermined pressure, the first predetermined pressure being lower than the second predetermined pressure. The concentration equipment includes a temporary storage unit, a homogenizing unit, and a particular concentration unit.

Processing of milk raw material produces a dairy salt. Preliminary treatment of the milk raw is carried out, with pasteurization and its concentration by nanofiltration through a filter with a pore size of 0.001-0.01 μm, subsequent filtration of the obtained nanofiltration permeate through a membrane module with a pore size of 0.0001-0.001 μm of a reverse osmosis unit, electrodialysis of the obtained RO retentate, concentration of the concentrate or its concentration and drying. The dairy salts may be manufactured and used to salt food products, beverages, granulated cottage cheese, potato chips, crackers, and dips. A masking fraction with organic acid, amino acid, fatty acid, and sugar portions successfully hides the off-notes otherwise associated with potassium compositions. Food products salted with any of the dairy salts described herein achieve reduced sodium content without compromising flavor.

Food products and systems and methods for their production involve subjecting pasteurized milk to a concentration process thereby forming liquid concentrated milk, then fermenting the liquid concentrated milk to form a fermented concentrated milk product. The fermented concentrated milk product is combined with a liquid emulsifying agent, thereby forming a food product. The food product is formed without the fermented concentrated milk product and the food product reaching a temperature of 145° F.

The present invention relates to a novel method for preparing acid-gellable whey protein aggregates in the form of concentrated suspensions or powders. Moreover, the present invention relates to a novel composition containing the acid-gellable whey protein aggregates, to a food product ingredient comprising the novel type of acid-gellable whey protein composition, and to a food product comprising the novel type of acid-gellable whey protein composition.

A demineralised whey powder is suggested which is obtainable by: (a) Separating raw milk, removing the cream; (b) Subjecting the skimmed milk such obtained to microfiltration or microdiafiltration, obtaining a whey protein-rich permeate P1 and a retentate R1 containing casein and GMP in the process; (c) Subjecting the permeate P1 to column chromatography separation, in which the lactoferrin contained therein remains on the column; (d) Subjecting the permeate, from which lactoferrin had been removed, to dialysis; and (e) Dehydrating the diluate such obtained.
