Claims48
A method of producing a standardized edible food labeled with a marker comprising the sequential steps of:
- providing a marker;
- uniformly distributing a known amount of said marker throughout an edible food component;
- and
- lyophilizing the marker and the edible food component.
A method of producing a standardized edible food labeled with markers comprising the sequential steps of:
- providing a first marker and a second marker, the first marker comprising biomass and the second marker comprising a radioactive isotope;
- uniformly distributing a known amount of the first marker throughout an edible food component;
- lyophilizing the first marker and the edible food component;
- reconstituting the first marker and the edible food component;
- adding the second marker to the first marker and the edible food component.
A method of producing a standardized meal labeled with a marker comprising the sequential steps of:
- providing an edible food component;
- lyophilizing the edible food component;
- reconstituting the edible food component;
- adding a marker to the reconstituted edible food component;
- and
- lyophilizing the marker and the reconstituted edible food component.
A meal comprising:
- an edible food component;
- a known amount of a marker uniformly distributed throughout the edible food component, said marker being a 13C marker derived from a biomass and chosen so that when ingested by a mammal with the meal either the absorption or metabolism of the marker may be monitored and correlated to a physiological function of the mammal or a therapeutically effective amount of the marker delivered to the mammal;
- wherein the edible food component has been lyophilized and reconstituted before said known amount of marker is uniformly distributed throughout the edible food component, and wherein the edible food component and the marker have been lyophilized together after said known amount of marker is distributed throughout the edible food component, so that the edible food component has been lyophilized twice.
A meal comprising whole eggs, wherein the whole eggs are bound to a known amount of a 13C marker derived from a biomass, said 13C marker chosen so that when ingested by a mammal with the meal either the absorption or metabolism of the marker may be monitored and correlated to a physiological function of the mammal or a therapeutically effective amount of the marker delivered to the mammal, wherein the whole eggs have been lyophilized and reconstituted before the 13C marker is added to the eggs, and wherein the whole eggs and 13C marker have been lyophilized together after the marker is added to the eggs, so that the whole eggs have been lyophilized twice.
