摘要： A method for production of near sterile whey protein concentrates is proposed, which comprises 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).

摘要： Fermented milk products, such as yoghurt and buttermilk, are produced by fermentation of a suitable raw material, such as milk, with different microorganism species, in such a way that microorganisms that are beneficial in the production stage but unfavourably affect the product quality during storage, are kept apart from the fermentation mixture by means of a semipermeable membrane. The process can be carried out in a fed batch system or continuously, preferably with continous pH control. The products so obtained have improved taste and storage properties.
