Claims
- 1. A process for the production of spice extracts from natural spice which comprises the steps of:
- (a) contacting a solvent gas, which in the dry supercritical state is effective to dissolve the essential oil component containing aroma constituents from the natural spice and leave a first spice residue containing flavor constituents, with the natural spice, for a time sufficient to extract the essential oil component of the spice and leave a first spice residue containing flavor constituents, the solvent gas being in dry supercritical state,
- (b) separating the aroma constituents from the solvent gas,
- (c) contacting a solvent gas, which in the wet supercritical condition is effective to dissolve the flavor constituents of the natural spices and leave a second spice residue, with the first spice residue, for a time sufficient to extract the flavor constituents of the first spice residue and leave said second spice residue, the solvent gas being in wet supercritical state,
- (d) separating the flavor constituents from the extraction solvent gas of step c,
- wherein the solvent gas in each of steps (a) and (c) is selected from the group consisting of carbon dioxide; saturated and unsaturated hydrocarbons containing up to about three carbon atoms; nitrous oxide; saturated and unsaturated halogenated hydrocarbons containing up to about three carbon atoms wherein the halogen is at least one of flourine and chlorine; sulfur hexaflouride and mixtures thereof.
- 2. A process according to claim 1 including the further steps of extracting the second spice residue with water to produce an aqueous extract, and removing at least a portion of the water from the aqueous extract.
- 3. Process according to claim 2, wherein the essential oil product of step b, the flavor constituent product of step d and the product of the water extract step are mixed.
- 4. A process according to claim 1 wherein the solvent gas in each of Steps (a) and (c) is carbon dioxide.
- 5. A process as in claim 1 wherein the flavor constituents are separated out of the presence of the product of Step (b), and the products of the two separating steps are thereafter mixed.
- 6. Process according to claim 1, wherein the temperature in each of steps a and c is up to 80.degree. C.
- 7. Process according to claim 1, wherein the flavoring constituents are separated from the extraction solvent gas of step c, in the presence of the product of step b.
- 8. Process according to claim 1, wherein the separation in each of steps b and d is effected by adjusting the temperature or pressure.
- 9. Process according to claim 1, wherein the natural spice is in ground condition.
