The disclosure discloses a milk protein concentrate-based microencapsulation wall material and microcapsules, and belongs to the technical field of microcapsule preparation. In the disclosure, liquid or solid microcapsules are prepared by performing cation exchange treatment on milk protein concentrates, and then using the treated milk protein concentrates as a wall material. The prepared microcapsules have good physical and chemical stability during storage, and are suitable for protecting active functional factors and to be applied in the fields of food, medicine, health care products, cosmetics, daily chemicals and the like.

There is provided a means for sterilizing lactoferrin at a high temperature in a short time while maintaining the activity of the lactoferrin. The present technology provides a method for producing a lactoferrin-containing aqueous solution, including a sterilization step of heat-sterilizing a lactoferrin-containing aqueous solution, in which the total mass content of proteins other than lactoferrin is 1/12 or less of the mass content of lactoferrin, at a temperature of 100° C. or more. The present technology also provides a lactoferrin-containing aqueous solution in which the total mass content of proteins other than lactoferrin is 1/12 or less of the mass content of lactoferrin, and which does not contain living bacteria.

The invention concerns a process for the treatment of a sweet whey material containing cGMP (caseinoGlycoMacroPeptide), said process comprising the following steps: Decationising the sweet whey material so as to obtain sweet whey material having a pH value of 1 to 4.5; Treating said sweet whey in a fluidized bed reactor comprising a specific volume of an anionic resin, at a temperature between 10 and 18 C., wherein said sweet whey contacts said resin for a sufficient amount of time so that the resin absorbs between 52% and 58% of the cGMP present in the sweet whey; andRecovering a protein material. Advantageously, the protein material is suitable for hypoallergenic infant formulae.
