Abstract
The invention relates to processes for preparing fertilized egg components using freeze-drying and/or extraction methods.
Claims11
A process for preparing a powdered sample of all or part of the contents of at least fertilized egg, the process comprising the steps of (i) substantially separating the contents of at least one fertilized egg from the shell;
- (ii) optionally filtering the contents to produce a solid or solid and semi-solid retentate, (iii) freezing the contents or retentate, (iv) freeze-drying the contents or retentate, (v) optionally, combining one or more freeze-dried contents or retentate, and (vi) pulverizing the contents or retentate to form a powder.
A process for producing a slurry of all or part of the contents of at least one fertilized egg, the process comprising the steps of (i) substantially separating the contents of at least one fertilized egg from the shell;
- (ii) optionally filtering the contents to produce a retentate, (iii) combining the contents or retentate in a container, (iv) blending, optionally with solvent added, the contents or retentate to produce a slurry, (v) optionally freezing the slurry to save for further processing.
A process for preparing a powdered sample of at least one embryo is provided, the process comprising the steps of (i) substantially separating the at least one embryo from at least one fertilized egg;
- (ii) optionally washing the at least one embryo, (iii) freezing the at least one embryo, (iv) freeze-drying the at least one frozen embryo, and (v) pulverizing the at least one freeze-dried embryo to form a powder.
A process for producing a powdered aqueous extract from a slurry of at least one embryo, or at least one embryo and some or all of the white albumen portion, the process comprising the steps of (i) mixing the slurry with an aqueous solution for a period of time, (ii) clarifying the mixture to produce an aqueous solution substantially free of solid material, (iii) separating the aqueous solution from the solid material, (iv) freezing the aqueous solution, and (v) freeze-drying the aqueous solution to produce a powder.
