Being dewaxing method of the orange oil due to designating that the orange oil is poured on filtration process as a condition, here, the oil is let flow alongside the porous membrane surface which is maintained at the temperature which is lower than the between 11 of the said process, the said membrane, has the average diameter of 0.05 - 5 micro meters, the aforementioned method. By this method, very high-level the orange oil which the dewaxing is done is produced.柑橘油をろ過プロセスにかけることを条件とすることによる柑橘油の脱ろう方法であって、ここで、油は該プロセスの間11℃より低い温度に保たれる多孔質膜表面に沿って流され、該膜が、0.05~5マイクロメートルの平均孔径を有する、前記方法。本方法により、非常に高度に脱ろうされた柑橘油が製造される。
