Relating X-ray Absorption and Some Quality Characteristics of Mango Fruit (<i>Mangifera indica </i>L.)

Abstract

X-ray absorption was used as an index to detect the quality of mango 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. 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 nondestructive indicator of the quality of mango.
