Disclosed is a process for the production of a commercial mineral whey product derived from a feed stream of milk or whey, said process including the steps of: primary de-mineralisation of the feed stream by nanofiltration to produce a substantially de-proteinated and lactose-reduced high potassium stream and a protein and lactose rich demineralised stream; secondary demineralisation of the high potassium stream, either by precipitation and subsequent separation of a predominantly calcium-phosphate complex, or by the removal of calcium by ion exchange; concentrating the high potassium stream to obtain a mineral rich concentrate having a total solids content of around 20 to 60% by weight, wherein around 50% of said total solids is ash; and further processing of said concentrated said high potassium stream into a desired form for storage and distribution. Also disclosed is a mineral whey powder manufactured by the above process. |
