Abstract
The process for the chromatographic fractionation of whey comprising passing whey through a column of an ion exchange material, thereafter passing water through said column as eluant, and collecting the aqueous effluent from said column as a plurality of fractions. Advantageously the ion exchange material is a polystyrene resin containing sulfonic acid groups neutralized with calcium ions and cross-linked with about 2 to 4% by weight of divinyl-benzene, and the eluant is demineralized water.
Claims8
The process for the chromatographic fractionation of dairy whey containing lactose, proteins and mineral salts into a protein fraction comprising passing said whey through a column of a cation exchange material in neutral form, said cation exchange material comprising a polystyrene resin containing sulfonic acid groups, thereafter passing an aqueous eluant consisting essentially of water through said column, and collecting a plurality of sequential aqueous effluents from said column as a plurality of separate fractions.
