Near infrared spectroscopy combined with chemometrics has been widely used in the field of food adulteration analysis because of its unique technical advantages. Principle and characteristics of the near infrared spectroscopy combined with chemometric techniques were discussed. This article expounded the principles and characteristics of chemometric technology, reviewed the applications of chemometric methods with high practicality, practicality chemometric methods, partial least squares, artificial neural network and support vector machine, which were widely used in the past ten years, in combination near infrared spectroscopy in food adulteration analysis. Finally, this article outlines the development prosepect of this technique.
