| Abstract: | The feasibility of rapid discrimination of black sesame paste brand by Fourier transform near-infrared(FT-NIR) spectroscopy was studied.Forty-eight black sesame paste samples of two brands were analyzed by NIR diffuse reflectance spectroscopy between 800 and 2 500 nm.The spectral differences were studied by principal components analysis(PCA),and classifications,according the brand,were carried out by Hierarchical cluster analysis,discriminant analysis(DA) and discriminant partial least squares(DPLS).When used to predict the brand of the validation set samples,models all gained a total accuracy of 100%.The results indicate that NIR spectroscopy technique with chemometrics methods offers effective discrimination capability for brands of black sesame paste commercial available in market. |
