1. A process for the production of spice extracts by extraction with a physiologically acceptable gas as a solvent in two stages, characterised in that the ethereal oils acting as odour component are removed from the spices in the first stage using a liquid gas of which the temperature is in the subcritical range and the pressure in the supercritical range whilst the flavour components are removed in the second stage using the same gas of which the temperature and pressure are both in the supercritical range, the extracts are separated off from the solutions obtained by changing the pressure and/or temperature and optionally mixed with one another. |
