Abstract

The present application relates to a method and apparatus for in-vivo characterisation of the quality and ripeness of fruits and vegetables in which the aroma at the surface of the fruit or vegetable is excited by light of a specific wavelength so as to induce luminescence of said aroma wherein the spectral distribution of the luminescence is detected. The values of parameters based on the intensity of the distribution are determined and changes are compared with predetermined deviation values to draw conclusions on the state of the tested quality of the fruit or vegetable.
