Abstract:
1. A method of manufacturing a whey in which a phosphorus content is not more than 12 mmol per 100 g of solids, and a combined total of a calcium content and a magnesium content is at least 10 mmol per 100 g of solids, the method comprising, in the following sequential order: via a first nanofiltration method, filtering monovalent minerals including chloride from a raw whey liquid thereby obtaining a low-chloride whey liquid as a retentate in which a chloride content has been reduced to not more than 30 mmol per 100 g of solids, reducing the phosphorus content and increasing the chloride content of the low-chloride whey liquid by passing the low-chloride whey liquid through an anion exchange resin in chloride form thereby obtaining an ion-exchanged whey liquid in which a phosphorus content is not more than 12 mmol per 100 g of solids and a molar ratio of a chloride content relative to a combined total of a sodium content and a potassium content (chloride/(sodium+potassium)) is 0.35 or greater, and via a second nanofiltration method, filtering chloride, sodium, and potassium from the ion-exchanged whey liquid thereby obtaining a whey liquid as a retanate in which the molar ratio is maintained at a value of 0.35 or greater, the phosphorus content is not more than 12 mmol per 100 g of solids, and a combined total of a calcium content and a magnesium content is at least 10 mmol per 100 g of solids in the whey liquid.
