A collaborative research project was conducted during the 2007-08 and 2008-09 mango season with an objective to develop a non-destructive method to identify and sort spongy tissue affected ‘Alphonso’ mango fruits using a soft X-ray imaging system, designed and developed by CEERI, Chennai, in collaboration with Dr. B.S. Konkan Krishi Vidyapeeth, Dapoli. A batch of ‘Alphonso’ mango fruits having different ripening stages as a treatments viz., T1 – 2 days after harvest, T2 – 3 days after harvest, T3 – 4 days after harvest, T4 – 5 days after harvest were exposed repeatedly to the X-ray imaging machine, calibrated by computing different algorithms, using base line data regarding physico-chemical properties of spongy tissue and healthy pulp of ‘Alphonso’ mango fruit. The machine could best detect and sort spongy tissue affected fruits from treatment (T3), followed by T4 and T2, but was less successful for T1. The machine could also detect fruit with air pockets.
