The present application relates to a method for preparing a dairy product based on the principle of forward osmosis, the concentrated dairy product prepared by the above method, and a continuous forward osmosis membrane system. Multiple concentration of the target solution is achieved by controlling the osmotic pressure difference between the solutions on both sides of the forward osmosis membrane, no heat source or strong external pressure is introduced, and the main nutrient content and nutrient ratio of the target solution are maintained. Compared with a reverse osmosis membrane concentration and a freeze concentration, the forward osmosis membrane concentration can greatly increase the concentration multiple of the dairy product, reduce the unit energy consumption, save the running cost. The scaled treatment of dairy product concentration is realized, and the microbial indicators, physical and chemical indicators and nutritional indicators of concentrated dairy products can meet the requirements of relevant standards.

A method for preparing a modified whey protein concentrate (WPC) or whey protein isolate (WPI) is described. It involves (a) providing an aqueous WPC or WPI solution having a protein concentration of 15-50% (w/v), at a pH of 4.7-8.5; (b) heat treating the solution to more than 50 DEG C, for a time that allows protein denaturation to occur the heat treating comprising heating the solution while under conditions of turbulent flow. At the end of the heat treatment, the heat treated material may be promptly transferred to a drier or to be mixed with other ingredients. The heat-treated WPC or WPI is not subjected to a mechanical shear process prior to the transfer other than where liquid is converted into droplets to facilitate drying. The modified WPC is useful in the manufacture of food and drinks where a high protein content is desired without undesirable changes in texture.

The present invention relates to a method of producing a liquid dairy concentrate, the method comprising: providing a liquid dairy ingredient having a fat content of at least 35 wt %; concentrating the liquid dairy ingredient by ultrafiltration and/or diafiltration to obtain a concentrated liquid dairy ingredient as the retentate; adding sucrose and/or trisodium citrate to form a modified retentate; blending the modified retentate with one or more further ingredients; and homogenising the blend to form a liquid dairy concentrate, wherein, during the step of blending the modified retentate with said one or more further ingredients, the modified retentate is at a temperature of at least 60 C.

The present invention relates to polymorphisms indicative of altered milk fatty acid composition in female milk-producing cattle. In particular, the present invention provides methods for selecting a cattle which possesses a genotype which in female milk-producing cattle is indicative of a desired milk fatty acid composition and cattle selected by said method. Further, the present invention provides milk produced by the female milk-producing cattle, methods for selective breeding and non-human gametes. Use of a nucleic acid molecule or an oligonucleotide in an in vitro method for determining the presence of at least one allele, which in a female milk-producing cattle is indicative of a desired milk fatty acid composition, is also part of the present invention.

The invention relates to pelleted ruminant feed, comprising, in pelleted or else subsequently re-crumbled form, a mixture of at least one solid particulate feed component with at least one rumen-unstable constituent which has been added to the mixture; to processes for their preparation and to their use in methods of altering the milk fat concentration.

A centrifugal separator for separating milk into a cream phase and a skim milk phase is described. The separator includes a centrifuge bowl, a disc stack of conical discs arranged inside the centrifuge bowl. The disc stack includes a first set of discs and a second set of discs, the discs in the disk stack includes distribution openings such that the milk passes the first set of discs before passing the second set of discs. The discs in the first set of discs are separated from each other by a first distance, and the discs in the second set of discs are separated from each other by a second distance which is smaller than the first distance.
