The invention concerns a method and a sorting apparatus for sorting potato products that are moved in a product flow through a detection zone, whereby irregular products are detected in the product flow and are separated from the product flow, characterized in that a light beam having a wavelength of in between 350 and 450 nm is directed towards said products in said detection zone and wherein the intensity of the light that is irradiated by the products is detected in a detection band from 460 nm to 600 nm, wherein a product is qualified as an irregular product and is separated from the product flow when said intensity is below a predetermined value. Further, the invention also concerns a method and a device for detecting the presence of solanine in potato products by means of fluorescence.
