USE OF A SOFT X-RAY IMAGING SYSTEM FOR ON-LINE DETECTION OF SPONGY TISSUE IN ‘ALPHONSO’ MANGO FRUIT

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.
