The invention relates to a method of preparing a whey-derived composition enriched in whey phospholipids and osteopontin (OPN) by membrane filtration, and preferably also enriched in other membrane components from whey. The invention furthermore relates to the whey-derived composition as such, use of the whey-derived composition for increasing the content of OPN in nutritional products, and to nutritional products comprising the whey-derived composition.

Methods and systems are provided for separation and/or purification of biomolecule(s) from a solution and for demineralization of a solution containing biomolecule(s) and ion(s). The methods and systems described herein include one or more ion exchange membrane(s), (e.g., ion exchange membrane(s) capable of water splitting), in an electrochemical cell, from which bound biomolecule(s) or ion(s) may be recovered from the membrane and separated from other components present in the solution by reversing the polarity of the electrodes. Using methods and systems described herein, biomolecules (e.g., whey proteins and lactose), and ions (e.g., milk salts), are able to be separated and recovered in their native forms with high biological value as premium food grade products. Methods and systems described herein offer a significant advantage over traditional processes used (e.g., in the food and beverage industry), for cost effective and chemical-free processing/extraction of valuable products from complex solutions such as whey.

A process for the coupled production of sweet whey and lactic acid from acid whey is suggested, comprising the following steps: (a) providing acid whey having a lactic acid content of about 0.1 to about 1% by weight; (b) nanofiltration of the acid whey, obtaining a first permeate P1 and a first retentate R1; (c) optionally, redilution of the first retentate R1 with water to reconstitute the initial dry matter content, and preparation of the second nanofiltration step; (d) nanofiltration or nano-diafiltration of the retentate R1, obtaining a second permeate P2 and sweet whey as a second retentate R2; (e) combining the two permeates P1 and P2 and subjecting the mixture to reverse osmosis, obtaining a third permeate P3 which, substantially, only contains water, and a concentrate of lactic acid as a third retentate R3.
