Methodological Study on the Detection of Trans Fatty Acid Content in Olive Oil by Gas Chromatography
Objective:To establish a gas chromatography method for the determination of 10 trans-fatty acids in olive oil and to verify the method.Method:After methylation,the Supelco SP-2560 capillary column was used as the analysis column,and the samples were detected by temperature program and hydrogen flame ionization detector.Result:The 10 kinds of trans fatty acids in olive oil could be separated well without interference from other components.The detection limit and quantitation limit,precision and recovery rate,durability and specificity of the method were all good.Conclusion:The method is accurate,reliable,simple and suitable for the determination of trans fatty acids in olive oil.
