Disclosed is a method for accurately controlling content of palmitic acid in olive oil. The method uses virgin olive oil as a raw material, and uses a mixed filler formed by lipase, inorganic base, a filtering aid, an adsorbent, and the like to remove impurities to prepare olive oil having a low palmitic acid content instead of conventional enzyme hydrolysis, de-acidification and impurity removal processes. The present invention is characterized in that the content of palmitic acid in olive oil is accurately controlled within a specific range of 7.5-12% by means of one-step treatment, and industrial production can be achieved.
