To our knowledge, there is no extensive study to classify bee pollen by geographical region in Algeria that has been conducted on bee pollen by application of FTIR spectroscopy in association with chemometrics treatments. This work aimed (Fig. ) to propose the model of classification of the Algerian pollen in samples from thirteen different regions and different plants in a simple and fast manner without destroying the sample, and this using ATR-FTIR spectroscopy combined with unsupervised multivariate statistical methods (PCA and HCA).
