Abstract : An X-ray computed tomographic (CT) technique was used to analyse the internal changes associated with the ripening process of mango. Mangoes were evaluated for X-ray absorption, density, moisture content, soluble solids, titratable acidity and pH. X-ray absorption of the fruit expressed in terms of CT number was used as an index to detect internal changes in the fruit. It was found that the CT number, moisture content, density and titratable acidity decreased with ripening time. Soluble solids and pH, however, increased during ripening. The CT image showed visible features of the internal structural changes between the fresh and ripened mangoes. An X-ray CT scanner provided high resolution images and highlighted the internal quality of the fruit.
