    • 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.
    • 含有具有抗氧化活性的香料提取物的油通过将极性溶剂中所含的香料提取物与油混合,从混合物中蒸发极性溶剂,向混合物中加入非极性溶剂来稀释混合物并将其混合 沉淀出混合物的成分,并搅拌,得到均质的非极性溶剂/萃取/油混合物,从该混合物中分离出沉淀,然后蒸发非极性溶剂相,得到含油香料提取物。 含有香料提取物的油可与含有香料提取物的其它极性溶剂混合,然后重复该过程以用香料提取物富集最终的油产物。
