Abstract

The present invention provides the method for the production of the egg containing antipathogenic bacteria specific antibodies (IGY) preventing gastritis, diarrhoea, and food poisoning by immunizing young hens with antigen proteins of E. coli causing enteritis, Helicobacter pylori causing gastritis, and Salmonella enteritidis and Salmonella typhimurium causing food poisoning. Simultaneously this invention also relates to the composition containing the specific IGY antibodies described above and the foodstuff such as the yoghurt and ice cream containing the antipathogenic IGY. Additionally, the present invention provides the separation method of the IGY containing protein powders from egg yolk. Particularly, this separation method involves diluting egg yolk with water at 1:1 ratio and adding the appropriate amount of ammonium sulphatewhich enables water-soluble protein and phospholipid to separate.

Description

technical field

[0001] The present invention provides eggs that contain specific antibodies (IgY) against pathogenic bacteria to prevent gastritis by immunizing chickens with antigenic proteins of E. , diarrhea and food poisoning methods, also provides a composition of protein powder mixed with specific antibodies as described above in an appropriate ratio, the composition is produced by immunization with four antigens alone, and food processed with milk, such as Yogurt and ice cream, which contain specific antibodies against pathogenic bacteria (IgY).

[0002] In addition, for the method of separating specific antibody protein powder, the method of separating protein and phospholipids is especially diluting egg yolk with distilled water at a ratio of 1:1, adding an appropriate amount of ammonium sulfate, which separates water-soluble protein from phospholipids, and separates egg yolk from water-soluble The protein method dilutes the separation solution with distilled water a...
