The present invention relates to a lactase solution comprising a lactase solution comprising less than 10 g/kg of poly and oligosaccharides, a process for the production of such a lactase solution from an untreated lactase solution, a sterilized lactase, whereby such lactose is filter sterilized in-line with the milk production process.

The invention concerns native whey protein for use in the treatment and/or prevention of intestinal infection or inflammation, in particular necrotizing enterocolitis. The inventors found that native whey protein provides a beneficial effect on intestinal infection or inflammation.

A low-bacteria milk powder with a WPNI of at least 2 is suggested, obtainable by (a) providing a milk component; (b) optionally, separating the cream from the milk component; (c) subjecting the milk component from which the cream had been optionally separated to microfiltration, obtaining a low-bacteria permeate P1 and a bacteria-contaminated retentate R1; (d) mixing the permeate with a liquid lipid phase and a solid active agent phase; (e) optionally, subjecting the mixture obtained in step (d) to a temperature treatment; and (f) processing the mixture of step (d) or (e) that had optionally been temperature-treated, obtaining a dry powder.

The invention concerns an infant formula product comprising intact and native whey protein for use in reducing or preventing allergic response. The infant formula product comprises whey protein having a nativity value of at least 90% and/or which is obtainable by a process comprising: (a) processing defatted milk into a casein stream, a whey protein stream and a lactose stream, by: (i) subjecting the defatted milk to microfiltration over a membrane capable of retaining bacteria and permeating milk proteins or to a pasteurization step, to provide a debacterialized milk; (ii) subjecting the permeate originating from step (i) to microfiltration over a membrane capable of retaining casein and permeating whey proteins, to provide a casein stream as retentate and a permeate comprising whey protein; (iii) fractionating the permeate originating from step (ii) into a whey protein stream and a lactose stream; (b) combining at least part of the casein stream, at least part of the whey protein stream originating from step (a) and a lactose source to obtain a recombined stream; (c) optionally pasteurization of the recombined stream from step (b), (d) using the recombined stream originating from step (b) or (c) in the manufacture of the infant formula product.

Methods for extracting protein from expired or spoiled milk is disclosed. In at least one embodiment, the method includes the steps of acid hydrolysis, first filtration, fine filtration, activation, salting out, degreasing, drying and packaging. Through the combined process of “protein activation” and “self-assembly salting out,” these methods enable the reuse and upcycling of expired and spoiled milk.

The invention concerns native whey protein for use in (a) improving intestinal maturation; and/or (b) reducing and/or preventing intestinal permeability. The inventors found that native whey protein provides a beneficial effect on intestinal maturation and permeability.

The present invention provides a novel process for preparing fortified milk compositions from whole mammalian milk. The process of the present invention generally involves converting dried mammalian milk into a fats-enriched fraction, a protein-enriched fraction, and a carbohydrate-enriched fraction. The process comprises treating the dried milk with a fats extracting agent to provide a fats-enriched fraction, and a residual fraction comprising proteins and carbohydrates; separating said fats-enriched fraction from the residual fraction; and removing the fats extracting agent from the separated fats-enriched fraction to produce a dry fraction of oily, fats-enriched material and a fraction enriched in proteins and carbohydrates.

The present invention relates to a method for treating raw human milk to produce treated human milk having undetectable levels of bacteria. The milk is skimmed to produce skim human milk then subjected to microfiltration to yield a filtrate which has undetectable levels of bacteria, including Bacillus cereus. The resultant human milk can be further processed, used and/or sold.
