Identification of Adulterated Natural Ginger Oil Using Gas Chromatography-Mass Spectrometry

A rapid and sensitive method was proposed for the identification of ginger oil adulterated with soybean oil using gas chromatography-mass spectrometry(GC-MS). The method was based on the identification of the characteristic components including methyl palmitate, methyl linoleate, methyl oleate and methyl stearate in soybean oil by GC-MS after ginger oil sample was derivatized by methyl ester. The necessity of derivatization with methyl ester was...
