Abstract:
A method for the sequential separation of whey proteins, comprising the steps of:a) providing:i) a cationic exchange resin contained within a container;ii) a whey sample, wherein said whey sample comprises at least one whey protein selected from the group consisting of immunoglobulin, .beta.-lactoglobulin, .alpha.-lactalbumin, lactoperoxidase, serum albumin, and lactoferrin; andiii) a cationic exchange resin;b) passing said whey sample through said resin under conditions whereby said whey proteins adsorb to said resin;c) collecting the flow-through from said cationic exchange resin, wherein said flow-through comprises lactose, minerals, lactic acid, and non-nitrogenous components;d) sequentially eluting said immunoglobulin and said .beta.-lactoglobulin from said cationic exchange resin;e) eluting said .alpha.-lactalbumin from cationic exchange resin;f) eluting said serum albumin from cationic exchange resin;g) eluting said lactoferrin from said cationic exchange resin; andh) eluting said lactoperoxidase from said cationic exchange resin;wherein a sequential separation of whey proteins is achieved.
