<p>The present invention provides new processes useful for separating whey proteins from whey protein-containing solutions using a novel anion exchanger which comprises a water insoluble, hydrophilic, water swellable, hydroxy (C2-C4) alkylated and cross-linked regenerated cellulose, derivatised with quaternary amino (QA) groups, wherein the level of substitution of the QA groups is 1.4 milli-equivalents per dry gram of anion exchanger (meq/g) or greater.</p> |
