Claim:
A nutritional composite material made according to a process comprising the steps of: (a) providing whey-derived milk minerals in solid form; (b) providing milk-derived proteins in solution; (c) exposing the milk-derived protein solution of step (b) to an ion exchange or filtration step to produce a solution comprising acidic proteins and enhanced-weight percent milk-derived basic proteins; (d) removing sodium-based minerals and sodium salts from the milk-derived protein solution of step (c); (e) purifying the whey-derived solid minerals of step (a) by mixing the minerals with a solvent and heating the resulting solution; (f) combining the purified whey-derived solid mineral solution of the previous step with the milk-derived protein solution of step (d); and (g) removing the solvent of the previous step to produce the nutritional composite material.
