Abstract:
A process for obtaining a fraction of a lactic raw material enriched in glycomacropeptide or caseinoglycomacropeptide (â€œGMPâ€ ) comprising the steps of:deionizing a lactic raw material for a time sufficient to obtain a substantially deionized lactic raw material having a pH of about 1 to 4.5 with the pH being adjusted, if necessary, to the recited range; contacting the substantially deionized lactic raw material with an anionic resin having a hydrophobic matrix for a sufficient amount of time and at a sufficient temperature to adsorb a substantial amount of GMP onto the anionic resin from the substantially deionized lactic raw material and to obtain a treated liquid material that does not contain substantial, amounts of GMP; separating the resin from the treated liquid material; and separating the adsorbed GMP enriched fraction from the resin.
