| 发明名称 | Process for obtaining immunoglobulins from colostral milk | ||
| 摘要 | Suggested is a process for obtaining immunoglobulins, wherein (a) colostral milk from days 0 to 7 is subjected to thermal treatment, skimming the cream,(b) the skimmed milk such obtained is subjected to sterile microfiltration thus producing a first retentate R1 which contains the casein, and a first permeate P1,(c) the first permeate P1 is subjected to ultrafiltration thus producing a second permeate P2 which contains lactose and minerals, and a second retentate R2, in which the immunoglobulins are concentrated. | ||

| 主权项 | 1. A process for obtaining immunoglobulins consisting essentially of: (a) colostral milk from days 0to 7is subjected to thermal treatment, skimming the cream, (b) the skimmed milk such obtained is subjected at a temperature of from about 50 to about 70° C. to a sterile microfiltration thus producing a first retentate R1 which contains the casein, and a first permeate P1, (c) the first permeate P1 is subjected at a temperature of from about 5 to about 15° C. to ultrafiltration thus producing a second permeate P2 which contains lactose and minerals, and a second retentate R2, in which the immunoglobulins are concentrated, and (d) the immunoglobulins thus obtained from the second retentate are separated off from by treatment with anion exchanger. | ||
