Method of manufacture of a protein concentrates containing immunological factors of lactic origin

摘要

The process is characterised by the following steps: Females bred for milk production are hyperimmunised by vaccinating them with an antigen of viral or bacterial origin, their milk containing the antibodies they have produced is collected, the cream and impurities are separated, the clarified and skimmed milk is coagulated, the cassein is separated, the product is filtered and ultrafiltered and the whey proteins are sterilised by filtration, the liquid is evaporated off and the product is dried under conditions which do not denature the immunoglobulins and which preserve the sterility. The protein concentrate may be incorporated in a food for babies and young children, such as a powdered or reconstituted milk or a gruel, and may be incorporated, for example, in a milk for premature babies.
