The relation of pear volume and it’s bruised volume by CT scan imaging

Abstract

The present research deals with the investigation of the relationship between the amount of the pears’ bruise subject to loading force and the volume of pears during the storage period. The selected pears were subjected to Quasi-static loading (wide edge and thin edge plates) and 5, 10, and 15-day storing durations were chosen for the investigation of the exerted force’s impact. The volume of pears and the bruise percentages were calculated before and after loading using the nondestructive CT-scan method. The bruise percentage was measured by dividing the bruise volume by the pear volume. The experiments result indicated that there is a positive correlation between the pear volume before loading and the bruise percentage for the wide edge and thin edge loading and that the more the volume of the pears the more the bruise percentage will be increased. The amount of loading force and the storage duration were not found having much of an influence on the bruise percentage for the pears that had been subjected to loading using thin-edge jaws and 5-day storage duration. The bruise percentage was observable for the 10-day storage duration. Also, no significant effect was evidenced for the 5-day storage duration of the pears that had been subjected to wide-edge plates’ loading for rates equal to 70 and below. But, the use of the same loading force, though being trivial, could be observed for the 10-day storage duration.
