Near–infrared spectroscopy combined with chemometrics has been widely used in the field of oil adulteration analysis because of its unique technical advantage. Principle and characteristics of the near–infrared spectroscopy combined with chemometric techniques were discussed. This article reviewed the applications of chemometric methods(clustering analysis,principal component analysis, support vector machine,artificial neural network,principal component regression and partial least squares),which were widely used in the past ten years by qualitative and quantitative analysis with high practicality,in combination near–infrared spectroscopy in oil adulteration analysis. Finally,this article outlines the development of this technique.
