The present invention relates to a method of recovering lactose from a lactose-containing liquid source comprising providing a lactose-containing liquid source, crystallising the lactose in the lactose-containing liquid source to generate one or more lactose-containing liquid streams, recovering a lactose-containing extract from the one or more lactose-containing liquid streams by subjecting the one or more lactose-containing liquid streams to filtration to remove cells, proteins, polypeptides, polysaccharides, lipid, ions or salts. The method also includes processing the lactose-containing liquid streams using at least nanofiltration, ultrafiltration and/or centrifugal separation and recycling the lactose-containing extract into the lactose-containing liquid source. |

1. A method of obtaining lactose from a lactose-containing liquid source comprising
subjecting a lactose-containing liquid source to a lactose crystallisation process to generate one or more lactose-containing liquid streams, subjecting the one or more lactose-containing liquid streams to one or more processes to generate a lactose-containing extract, the one or more processes comprising i) a first step, to remove one or more of cells, proteins, polypeptides, polysaccharides, lipid, ions or salts, comprising
a) centrifugal separation to produce a light phase and a heavy phase with optional ultrafiltration or nanofiltration of the light phase, orb) ultrafiltration to generate an ultrafiltration permeate and an ultrafiltration retentate, and ii) a second step comprising nanofiltration of
a) the light phase from the centrifugal separator, orb) the permeate from ultrafiltration, orc) the retentate from nanofiltration, adding at least a portion of the lactose-containing extract to the lactose-containing liquid source before, during or after entry into the crystallisation process. |
