Process for producing a composition for increasing muscle mass
A process for producing a composition from a biological source, which composition is preserved and, especially pathogen free and is storage stable, preferably at room temperature. Embodiments of the invention provide a process for producing a composition from eggs.
1. A process for producing a composition for increasing muscle mass, said process comprising:
providing raw liquid egg yolk, raw liquid whole egg or raw liquid egg white originating from eggs,
diluting with a diluent and then concentrating the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white to a fraction containing the egg yolk membrane and/or the chalazae,
and subjecting the concentrated fraction to a step of preservation while maintaining the temperature at or below 38° C., wherein the step of preservation is selected from subjecting the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white to a high pressure treatment of at least 4500 bar for at least 1 min, from subjecting the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white to a pulsed electric field treatment of at least 5 kV/cm at a flow rate of 30 L/h, and from a combination of the high pressure treatment and the pulsed electric field treatment to provide a preserved liquid egg yolk, preserved liquid whole egg or preserved liquid egg white so that a composition for increasing muscle mass is produced.
2. The process according to claim 1 , wherein the step of preservation consists of the high pressure treatment, wherein the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white is filled into containers, the containers are sealed and subjected to the high pressure treatment.
3. The process according to claim 1 , comprising drying the preserved liquid egg yolk, preserved liquid whole egg or preserved liquid egg white subsequent to the step of preservation.
4. The process according to claim 3 , wherein drying includes at least one of freeze-drying and fluidized bed drying.
5. The process according to claim 1 , wherein the step of providing comprises opening eggs and separating the egg yolk from the white of egg.
6. The process according to claim 1 , comprising cooling the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white to a maximum temperature of 10° C. prior to the step of preservation.
7. The process according to claim 1 , comprising degassing the raw liquid egg yolk, raw liquid whole egg or raw liquid egg white prior to the step of preservation.
8. The process according to claim 1 , wherein the fraction containing the egg yolk membrane and/or the chalazae is a high density fraction obtained by centrifugation and/or a larger size fraction obtained by size separation.
9. The process according to claim 1 , wherein subsequent to the step of preservation, the preserved liquid egg yolk, preserved liquid whole egg or preserved liquid egg white is dried and subsequently admixed with a solution of a sugar, a sugar alcohol and/or a sugar polymer and dried for encapsulating the egg yolk, whole egg or egg white.
