Abstract
A process is disclosed for the separation of macromolecules from a fluid substance containing the macromolecules. The process comprises contacting the fluid substance with discrete porous particles having an interconnected porosity throughout which provides an extended surface area and a pore structure such as will allow the macromolecules to permeate the particles and be sorbed, the discrete porous particles being selected such that a proportion thereof have acidic surfaces for contacting the macromolecules in the fluid substance and a proportion thereof have basic surfaces for contacting the macromolecules in the fluid substance. A process for the separation of protein from milk whey solution is also disclosed.
