Abstract
Fourier transform near infrared spectroscopy analysis (FT-NIR) of saffron is used for first time in saffron.
Its principal advantage is speed analysis, and it does not require sample treatment either.
Using Principal Component Analysis (PCA), saffron samples from Spain, Iran and China were clearly differentiated.
Other parts of the flower, as the styles, were also analysed being possible its differentiation among the saffron stigmas.
The sensitivity for each sample in its own family group, and its specificity, was in both cases 100%.
