Patent ID: 7750117

Claim:
A method for producing a feed containing heat-stabilized egg antibodies, the method comprising the steps of: mixing an egg white, an egg yolk and at least one saccharide selected from a monosaccharide, a disaccharide, a polysaccharide, an alkylated monosaccharide, an alkylated disaccharide, an alkylated polysaccharide, a monosaccharide alcohol, or an alkylated monosaccharide alcohol to form an egg liquid suspension, said egg yolk containing an egg antibody produced in response to antigen inoculation; and spray drying the egg liquid suspension to form an egg powder; and processing the egg powder to provide a feed containing heat-stabilized egg antibodies, said processing step including exposing the egg powder to an antigen-binding-activity-destroying temperature of at least 70° C; wherein the heat-stabilized egg antibodies in the feed produced by said method loses less of its antigen-binding activity in comparison to an egg yolk antibody retaining at least 20% of its antigen-binding activity after being exposed to said antigen-binding-activity-destroying temperature.
