Fuente: WIPO "milk" The present invention relates to a process for producing a demineralized milk that enables excellent reduction in the amount of monovalent minerals while suppressing any reduction in the amount of divalent minerals, as well as a demineralized milk produced using the above process, a process for producing a cheese and whey from the demineralized milk, and a cheese and whey produced using the above process. In the present invention, a demineralized milk having a significantly reduced amount of monovalent minerals is obtained by passing a raw milk through an anion exchange resin in chloride form to effect anion exchange so that a value for the chloride ion concentration within the raw milk is increased to the same value as the concentration of monovalent mineral cations contained within the raw milk, and removing monovalent minerals contained within said raw milk following said anion exchange using a nanofiltration process. Further, a cheese and whey can be produced by heating the obtained demineralized milk to produce a curd, and then separating the curd from the liquid other than the curd by solid-liquid separation.
