Abstract
A method for production of near sterile whey protein concentrates is proposed, which includes the following steps: (a) Ultrafiltration of whey at a temperature of about 2 to about 25° C. to produce a first retentate R1 and a first permeate P1; (b) Microfiltration of the retentate R1 from step (a) at a temperature of about 2 to about 35° C. to produce a second retentate R2 and a second permeate P2; (c) Ultrafiltration of the second permeate P2 from step (b) at a temperature of about 6 to about 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).
Claims19
A process for the preparation of whey protein concentrates low in germs, comprising the following steps:
- (a) ultrafiltrating whey at a temperature of about 2 to about 25° C. to produce a first retentate R1 and a first permeate P1;
- (b) microfiltrating said first retentate R1 from step (a) using a microfiltration membrane having an average pore diameter of from about 0.8 μm to about 1.6 μm at a temperature of from about 6 to about 35° C. to obtain a second retentate R2 and a second permeate P2;
- (c) ultrafiltrating said second permeate P2 from step (b) at a temperature of from about 2 to about 25° C. to obtain a third retentate R3 and a third permeate P3;
- (d) pasteurizing said third retentate R3 from step (c);
- and
- (e) drying said pasteurized product from step (d) to obtain a whey protein concentrate.
