Abstract:
1. A process for the demineralisation and fractionation of whey or raw milk the process consisting essentially of: a) subjecting the whey or raw milk to ultrafiltration to provide a retentate fraction and a whey permeate; b) concentrating the whey permeate by nanofiltration to provide a concentrated lactose rich retentate; c) subjecting the nanofiltration retentate to ion permeation or ion exclusion chromatography at elevated temperatures of between 50° C. and 80° C., using an appropriate resin; d) eluting the nanofiltration retentate in various fractions from the resin using water as the eluent; e) eluting a lactose rich fraction from (d) with low mineral content from the ion permeation chromatography resin; and f) adding the lactose rich fraction from (e) to the ultrafiltration retentate fraction obtained from (a) to provide demineralised whey.
