This paper presents noninvasive assessment of mango ripening using fluorescence spectroscopy. Fluorescence spectra have been recorded from the peel of Dusehri mango using Light-Emitting Diode at 460 nm as an excitation source. Results suggest that carotenoids pigments fluorescence depicts similar results as chlorophyll pigments for fruit maturity assessment. The argument is further strengthened by recording the fluorescence spectra of mango pulp using the same experimental setup. It has also been demonstrated that for the Langra mango, where the peel remains green even after fully ripening, the fluorescence peaks at 680 nm give false negative results. Our studies suggested that the carotenoids fluorescence emission at 540 nm, which exists in each case, may be useful for assessing the ripening stages of mangoes.
