Method for preparing a protein composition and an infant formula containing same

摘要

A process for the manufacture of an infant formula predominately based on a lactic raw material derived from whey whose amino acid composition is similar to that of human milk comprises micro-filtrating animal milk, which has not been subjected to a heat treatment or has been subjected to pasteurization on a membrane of porosity of 0.1-0.2 microns. The permeate is concentrated and then demineralized by electrodialysis without the use of ion- exchange decationization to obtain a protein composition and casein in the microfiltration retentate, acid casein or caseinate fat and where appropriate minerals and trace elements are added to the protein composition.
