Abstract : Mango is known as King of fruits and it belongs to the genus Mangifera of the family Anacardiaceae. Mango has become naturalized and adapted throughout the tropics and subtropics. Defect of internal break down causes browning or blackening of arils, which gives a typical foul smell if unnoticed. The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the world's most destructive fruit pests, these fruit fly insect is commonly find in the mango fruit. These internal defects cannot be identified from external appearance, which is a serious threat to the mango processing industry as well as export resulting in rejections and quality reduction. X-ray inspection has a distinct advantage over other detection techniques, as it is non-destructive imaging of interior features of sample which detects internal defects. Soft X-ray emission spectroscopy is an experimental technique for determining the electronic structure of materials. A continuous soft X-ray system with a semi-conductor detector was used to detect the internal quality of the fruit. Thus the present study is one of soft x-ray technique to find the internal defects in mango. As to conquer and sustain the international market, there is a need for export of high quality products with no internal defects. The objectives of this study is to determine the internal defects in mango with fruit fly insect using soft x ray and to develop the algorithm for classification of defective mango from healthy one.
