| Abstract_FL | A simple method was established to detect the fatty acid alkyl esters(FAAEs) in olive oil usingthe commercial silica gel solid phase extraction column to purify the olive oil, and gas chromatography -mass spectrometry (GC - MS) as the detector. The FAAEs were well separated and detected. The detectionlimits were 1. 0 mg/ kg, and the average recoveries were in the range of 99. 05% -111. 13% withthe relative standard deviations (RSDs) in the range of 0. 50% -6. 70%. This method could be used forthe determination of different grades of olive oils, and provide technical support for the identification ofadulteration of extra virgin olive oil. |
