摘要
(US20150230484) A process for producing lactose-free milk products is proposed in which (a) skimmed milk is subjected to an ultrafiltration or to a combination of dia- and ultrafiltration, (b) the lactose-free retentate R1 is fed to a storage container and the lactose-containing permeate P1 is fed to an enzyme reactor, (c) an amount of lactase sufficient for the enzymatic degradation of the lactose present therein is added to the permeate P1, (d) the reaction mixture obtained in this way is subjected to a nanofiltration, (e) the lactose-free permeate P2 is conveyed to the storage container and mixed with the lactose-free retentate R2, and (f) the retentate R2, which still comprises unreacted lactose and enzyme, is returned again to the enzyme reactor.

(US20150230484) 1. Process for producing lactose-free milk products, wherein (a) skimmed milk is subjected to an ultrafiltration or to a combination of dia- and ultrafiltration,   (b) the lactose-free retentate R1 is fed to a storage container and the lactose-containing permeate P1 is fed to an enzyme reactor,   (c) an amount of lactase sufficient for the enzymatic degradation of the lactose present therein is added to the permeate P1,   (d) the reaction mixture obtained in this way is subjected to a nanofiltration,   (e) the lactose-free permeate P2 is conveyed to the storage container and mixed with the lactose-free retentate R2, and   (f) the retentate R2, which still comprises unreacted lactose and enzyme, is returned again to the enzyme reactor. 2. Process according to claim 1, carried out either continuously or discontinuously. 3. Process according to claim 1, wherein the ultrafiltration of the skimmed milk is performed by a membrane made of stainless steel, polymeric materials, ceramic, aluminium oxide or fabrics. 4. Process according to claim 1, wherein the ultrafiltration of the skimmed milk is carried out with membranes which have a pore diameter of about 1000 to 50 000 daltons. 5. Process according to claim 1, wherein the ultrafiltration of the skimmed milk is carried out at temperatures in the range from 4 to 55 deg. C. 6. Process according to claim 1, wherein the hydrolysis is carried out at an enzyme concentration of from about 180 000 to 250 000 FCC units of lactase per kg of lactose to be reacted. 7. Process according to claim 1, wherein the hydrolysis is carried out at a temperature in the range from 23 to 27 deg. C. 8. Process according to claim 1, wherein the hydrolysis is carried out at a pH in the range from 6 to 7. 9. Process according to claim 1, wherein the nanofiltration of the hydrolysis product is performed by a membrane made of stainless steel, polymer materials, ceramic, aluminium oxide or fabrics. 10. Process according to claim 1, wherein the nanofiltration of the hydrolysis product is carried out with membranes which have a pore diameter of from about 100 to 2000 daltons. 11. Process according to claim 1, wherein the nanofiltration of the hydrolysis product is carried out at temperatures in the range from 4 to 55 deg. C. 12. Device for producing lactose-free milk products comprising: (a) an ultrafiltration unit UF,   (b) a storage and mixing container M,   (c) a stirred reactor R, and   (d) a nanofiltration unit NF,   wherein   (i) the retentate side of the UF unit is connected to the storage and mixing container and the permeate side is connected to the stirred reactor,   (ii) the stirred reactor is connected to the NF unit, and   (iii) the permeate side of the NF unit is connected to the storage and mixing container and the retentate side is connected again to the stirred reactor in the form of a loop.
