Spice essential oils produced by supercritical CO2 extraction technology can well preserve the natural flavor and have no problem of solvent pollution. Moreover,the extraction technique is simple and the production cycle is short. In this paper,production of 7 kinds of spice essential oils by use of the supercritical CO2 extraction technology was introduced,and in the meantime,extracted parameters,extraction rates and yields of each were presented.
