Subjecting a milk protein concentrate to cation exchange depleting the calcium content to produce a gel

摘要

A method of producing a modified milk protein concentrate (MPC) suitable for producing a gel comprises subjecting an aqueous solution of unmodified MC to cation exchange using a food approved cation exchanger containing monovalent cations to obtain a substitution of monovalent cation for divalent cation in the modified MPC sufficient to deplete the calcium content (mmoles of calcium per kg of total protein) of the modified MPC to be 20-85% of the calcium content of the unmodified MPC and recovering the MPC.
