A low-mineral quark matrix is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step and/or a reverse osmosis step, producing a retentate R1, which represents a dairy protein concentrate, and a permeate P1, (c) subjecting the permeate P1 to an electrodialysis step, producing a salt-depleted diluate D1, (d) combining the diluate D1 with the retentate R1, (e) subjecting the combination product such obtained to heat treatment until denaturation sets in, (f) fermenting the denaturation product such obtained by the addition of starter cultures and rennet, and (g) adjusting or standardising the fermentation product such obtained to defined dry matter and protein contents.

A quark matrix having improved taste characteristics is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to a microfiltration step, obtaining a first retentate R1, which represents a first dairy protein concentrate, and a first permeate P1, (c) subjecting the permeate P1 to an ultrafiltration step and/or a reverse osmosis step, obtaining a second retentate R2, which represents a second dairy protein concentrate, and a second permeate P2, (d) subjecting the permeate P2 to an electrodialysis step, obtaining a salt-depleted diluate D1, (e) combining the diluate D1 with the retentate R1, (f) subjecting the combination product such obtained to heat treatment until denaturation sets in, (g) fermenting the denaturation product such obtained by adding starter cultures and rennet, and (h) adjusting the fermentation product such obtained to defined dry matter and protein contents.

A quark matrix having improved taste characteristics is suggested, which is obtainable by (a) subjecting raw milk to heat treatment, separating the cream, (b) subjecting the skimmed milk such obtained to an ultrafiltration step, a microfiltration step, and/or a reverse osmosis step, producing a high-protein retentate R1 and a high-lactose permeate P1 in the process, (c) enriching the retentate with an amount of lactose which corresponds to the amount that had been separated in the ultrafiltration step as permeate before, (d) subjecting the enrichment product such obtained to heat treatment until denaturation sets in, (e) fermenting the denaturation product such obtained by adding starter cultures and rennet, and (f) adjusting the fermentation product such obtained to defined dry matter and protein contents.

Embodiments disclosed herein relate to an osmotic milk concentrator having a nutrient fortified draw solution and related methods. The osmotic milk concentrator includes at least one draw material reservoir, at least one human milk reservoir, at least one semi-permeable membrane between the at least one draw material reservoir and the at least one human milk reservoir.

Methods of making a zero sugar dairy-based food product and a zero sugar dairy-based food product are provided. The dairy-based food product includes a protease, an acyl transferase, a lactase, a skim milk, at least one of an additional ingredient selected from a group consisting of a probiotic, an artificial flavoring, a natural flavoring, a cream, a vitamin, a pectin, an oil, and combinations thereof, and an amount of water. The dairy-based food product further includes a sugar content of between 0 wt % and 0.4 wt %.

The present invention provides a process of producing a lactose concentrate, said process comprising the step of subjecting a partially demineralised aqueous lactose isolate to electrodialysis to produce a biotin-reduced lactose isolate containing at least 90% lactose by weight of dry matter and less than 2 mg ash per gram of lactose, and containing: 0.02-1.5 mg sodium per gram of lactose; 0.02-2 mg potassium per gram of lactose; 0.05-1.5 mg chloride per gram of lactose; 0.01-0.25 g biotin per gram of lactose.

The present invention also relates to a demineralised lactose concentrate having a reduced biotin content that can be produced by the aforementioned process. The invention further relates to an oligosaccharide-enriched biotin-reduced fraction that is obtained when lactose is separated before or after the electrodialysis step.

The invention relates to a method for treating protozoal gastrointestinal disorders in immunocompromised patients. It includes a method for the isolation of a factor from the milk of hyperimmunized animals in a substantially pure form, and to the use of said factor in combination with vitamins and minerals.

Disclosed are processes for producing cultured dairy products, such as yogurt, that are shelf-stable without refrigeration. Such processes can include contacting a milk base having from 0.5 to 1.9 wt. % milk sugar with a lactic acid bacteria culture and aseptically packaging in a container, followed by storage under conditions suitable to result in a pH of less than 4.7.
