Method for producing eggs containing anti-pathogenic bacterial antibodies (IgY: Immunoglobulin Yolk) and yogurt and ice cream containing said IgY

摘要

The present invention provides the method for the production of the egg containing anti-pathogenic bacteria specific antibodies (IgY) preventing gastritis, diarrhea, 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 composition containing the specific IgY antibodies described above and the foodstuff such as the yogurt and ice cream containing the anti-pathogenic 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 sulfate which enables water-soluble protein and phospholipid to separate.
