Abstract : X-ray absorption was used as an index to detect the quality of mangoes, based on its relationship with density, moisture content, soluble solids, titratable acidity and pH. A regression equation was obtained between the computed tomography (CT) number and the physicochemical properties based on the principle of X-ray absorption capacities of the fruit. The CT numbers of intact mangoes were positively correlated with density, moisture content and titratable acidity over the 3-week postharvest ripening time. The soluble solids and pH were inversely related with CT number. The results suggest that CT number measurements on intact fruit can be used as a non-destructive indicator of mango quality.
