Systems and methods for filtering dairy may filter milk with a wide-pore filter to produce a wide-pore retentate and a wide-pore permeate, wherein the wide-pore retentate may comprise casein and beta-lactoglobulin. The systems and methods may further ultra-filter the wide-pore permeate to produce an ultra-filtered retentate and an ultra-filtered permeate, wherein the ultra-filtered retentate comprises alpha-lactalbumin. The systems and methods may further nano-filter the ultra-filtered permeate to produce a nano-filtered retentate and a nano-filtered permeate, wherein the nano-filtered retentate comprises lactose. The systems and methods may further perform reverse osmosis (RO) on the nano-filtered permeate to produce a reverse osmosis retentate and a reverse osmosis permeate.

The present invention provides a method for the production of whey proteins in a single step process using combination of chromatography and membrane filtration technique, comprising treating cotton cloth with a mixture of chlorosulphonic acid and chloroform and then subsequently treating it with chloroform, dilute NaOH, glycine and water to recover modified cotton cloth as the product, thereafter fixing product in a membrane filtration device equipped with modified flow pattern and then equilibrating it with equilibration buffer, followed by loading of whey for adsorption of protein on the product and washing of the product with equilibration buffer, thereafter elution of adsorbed proteins with elution buffer, and then regeneration of the product by treating it with dilute HCl and water to reuse the product.

A demineralised whey powder is suggested which is obtainable by: (a) Separating raw milk, removing the cream; (b) Subjecting the skimmed milk such obtained to microfiltration or microdiafiltration, obtaining a whey protein-rich permeate P1 and a retentate R1 containing casein and GMP in the process; (c) Subjecting the permeate P1 to column chromatography separation, in which the lactoferrin contained therein remains on the column; (d) Subjecting the permeate, from which lactoferrin had been removed, to dialysis; and (e) Dehydrating the diluate such obtained.
