A method for preparing a cultured dairy product comprising: blending water, ultra-filtered milk and other ingredients to establish a dairy base, fermenting the dairy base to establish an intermediate yogurt product, adding a fat into the intermediate yogurt product, and blending the fat and intermediate yogurt product to produce a high fat and low carb yogurt. The amount of lactose in the dairy base is minimal, basically just enough to enable fermentation. On the other hand, instead of maintaining a low fat level, the fat, preferably a milk fat from butter, is added to increase the overall fat content to establish an overall high fat, low carbohydrate finished yogurt product.

The invention relates to a process for the treatment of animal skim milk and for the production of an infant formula base product from animal skim milk, which process is highly efficient and cost effective, as only membrane filtration techniques, such as microfiltration and ultrafiltration, are required. By carefully controlling the process parameters, a product is obtained in which most of the major components are within the desired range for an infant formula base product. The invention also relates to products obtainable by the process according to the invention.

The invention relates to a low-sugar acidified product, preferably yogurt or quark, and to a process for its preparation, wherein a milk raw material having a lactose content in the range from about 0.6 weight-% to 2.5 weight-% is used as a starting material.

The invention relates to the use of milk derived, denatured retentate in the preparation of milk-based compositions, which may be aerated or non-aerated, comprise a skimmed mild source, and/or have less than 0.5% w/w fat. The milk derived, denatured retentate allows the formation of microbubbles in an aerated skimmed milk composition, and thus retains certain desirable sensory perception characteristics such as a good mouthfeel and perceived thickness.

The present invention relates to dairy and milk treatment industries for obtaining lactose-free milk and assessment of byproduct in particular, particularly to milk treatment industry through different separation means such as micro and nanofiltration equipment. One of the purposes of this invention is to provide a delactosed or lactose-free milk with sensory profile equivalent to a normal pasteurized milk using essential separation steps to reduce product costs. Another purpose of this invention is to determine the effect of milk natural components concentration on organoleptic properties to achieve the first purpose of this invention. Another purpose is to determine percentage between retentate and permeate to get a sensory profile equivalent to a normal pasteurized milk.

The invention relates to a powdered human milk fortifier comprising a protein component typically present in an amount ranging from 6 wt/wt % to 20 wt/wt % of the fortifier powder, and a fat component typically present in an amount of from about 0.1 wt/wt % to 10 wt/wt % of the fortifier powder and a carbohydrate component selected from the group of Lactose and Oligosaccharides present in the in an amount from 50 wt/wt % to 75 wt/wt % of the fortifier powder; a moisture in the powdered milk fortifier in present in quantity of about 1.5 wt/wt % to about 4.5 wt/wt % of the powdered human milk fortifier; nutrients in the powdered milk fortifier selected from the group of Nucleotides, Minerals including but not limited to calcium, phosphorous, IgA, IgM, IgG, Lactoferrin, Nucleotides, Linolenic acid and Growth factors alike.

The invention further provides a powdered human milk lipid rich fortifier with a fat component in a quantity ranging from 40 wt/wt % to about 80 wt/wt %, further in where the lipids are derived from human milk and a moisture component in quantity ranging from 1.5 wt/wt % to about 4.5 wt/wt %; and nutrients selected from the group of Nucleotides, Minerals including but not limited to calcium, phosphorous, IgA, IgM, IgG, Lactoferrin, Nucleotides, Linolenic acid and Growth factors alike.

The invention presents an energy rich human milk powder with an energy content in a quantity ranging from 70 cal/100 mL to about 90 cal/100 mL; a moisture component in a quantity ranging from 1.5 wt/wt % to about 4.5 wt/wt %; and nutrients selected from the group of Nucleotides, Minerals including but not limited to calcium, phosphorous, IgA, IgM, IgG, Lactoferrin, Nucleotides, Linolenic acid and Growth factors alike.

Preferably, the freeze dried human milk fortifier is provided in a unit dose container which holds from about in which about 0.5 gm to about 10 gm of said fortifier. The instant invention also relates to a method of providing nutrition to preterm infants by adding a fortifier powder to human milk and administering the fortified human milk to a premature infant. The invention further provides a method of promoting growth of a premature infant by administering fortified human milk to a premature infant.

The present invention relates to a process for microparticulating of an ideal whey protein in a solution. The present invention relates also to microparticulated ideal whey protein preparation. In addition, the present invention relates to use of the microparticulated ideal whey protein preparation in milk based products and/or dairy products. Further, the present invention relates to a milk based product and/or a dairy product containing a microparticulated whey protein preparation.

The present invention is directed to nanofiltration (NF) composite membranes comprising at least one polymeric porous substrate layer (S) and at least one porous selfassembled supramolecular membrane layer (F); a method of preparing such composite membranes; method of separation/filtration/purification of heavy metal cations, inorganic anions, and organic small molecules by applying such composite membranes; as well as filter cartridges and filtration devices comprising said composite membranes.

Exosome purification methods involve use of a whey composition as an exosome source. Exosomes are isolated by subjecting the whey composition to a first ultrafiltration, which yields a first permeate and a first retentate. The first retentate may then be subjected to a second ultrafiltration, yielding a second permeate and a second retentate. During the second ultrafiltration, the first retentate may be treated with carbon dioxide. The second retentate may then be subjected to a third ultrafiltration, yielding a third permeate and a third retentate. The third permeate may then be optionally dried to yield an exosome powder.

A method of producing sialyloligosaccharides a sialyloligosaccharides-containing source that also contains carbohydrates and minerals. The process includes subjecting the source to a temperature of from about 67 C. and (i) filtration with a heat-resistant filter at a temperature of about 35 to about 95 C. to produce a first retentate and first permeate, or (ii) centrifugal separation to produce a light phase and a heavy phase and filtration of the light phase at a temperature of about 50 to about 70 C. to produce a first retentate and first permeate, (b) nanofiltration of the first permeate, or nanofiltration and diafiltration of the first permeate, to produce a second retentate and second permeate, and (c) concentration of the second retentate, to produce a sialyloligosaccharide-containing extract.
