A method for production of near sterile whey protein concentrates is proposed,whichcomprises the following steps:(a) Ultrafiltration of whey at a temperature of about 2 to about 25°C to produce a firstretentate R1 and a first permeate P1(b) Microfiltration of the retentate R1 from step (a) at a temperature ofabout 2 to about35 °C to produce a second retentate R2 and a second permeate P2(c) Ultrafiltration of the second permeate P2 from step (b) at atemperature of about 6 toabout 25 °C to produce a third retentate R3 and a third permeate P3(d) Pasteurization of the retentate R3 from step (c)(e) Drying of the pasteurized product from step (d).
