Abstract
An oil containing a spice extract which has antioxidant activity is prepared by mixing a spice extract contained in a polar solvent with an oil, evaporating the polar solvent from the mixture, adding a non-polar solvent to the mixture, to dilute the mixture and to precipitate constituents of the mixture, and stirring to obtain a homogenized non-polar solvent/extract/oil mixture, separating precipitate from that mixture and then evaporating the non-polar solvent phase to obtain an oil containing spice extract. The oil containing the spice extract may be mixed with further polar solvent containing the spice extract, after which the process is repeated to enrich the final oil product with spice extract.
