摘要： Near infrared spectroscopy (NIRS) in the transreflection mode combined with chemometrics was used to identify Camellia oil. The samples set contained 163 spectra of qualified (n=97) and unqualified (n=66) have been collected and scanned, the spectral data were pretreated and selected for effective variables. In the wavenumber range 5750 cm(-1) to 6000 cm(-1), the optimal combination of pretreatments (smoothed, first derivative, and autoscaling) was adopted to process spectra. Unsupervised classification-principal component analysis (PCA) was firstly adopted to classify, and then supervised classification-discriminant analysis (DA) was used to build calibration model to predict. Satisfactory results were obtained by PCA and DA, the correct recognition rates of two methods can reach 98. 8%. The results showed that NIRS can be used as a simple, rapid, nondestructive and reliable method to identify Camellia oil.
