这时，需要通过超高温，己烷溶剂（hexane solvent），和碱将油提炼出来，然后经脱色，冬化和除臭处理，去除油中的有害物质，最后“生产”出来的油无味，无香，是B类精炼橄榄油。

Methods: Active carbon tube adsorption and solvent desorption were used for sampling hexane and analysis was performed by GC(FID).
方法：以活性碳管采集空气中正己烷，用二硫化碳解吸后气相色谱（FID）测定。
Therefore, it is possible to use the cheap solvents (mixture of methanol and water) instead of the expensive hexane and acetone when the Accelerated Solvent Extraction method is employed.
这表明采用加速溶剂提取技术，可用价格较低的甲醇取代昂贵的正己烷和丙酮。
