Abstract
The invention concerns a method for discerning and sorting suitable products in a product flow having a certain concentration of a component versus anomalous products having this component in an anomalous concentration, whereby a beam of light strikes these products, and the absorption of this beam of light by said component in the products is detected by measuring the intensity of the light reflected by the products at least at a wavelength or in at least a wavelength band which is situated between 900 nm and 2500 nm in order to generate a detection signal on the basis of said absorption, whereby a product will be identified as an anomalous product if said detection signal exceeds a threshold value.
