Nondestructive Methods for Identifying Injury to Vapor Heat-Treated Papaya

Polygalacturonase, a softening enzyme, influenced the development of physiologically injured fruit treated with vapor heat. Development of a nondestructive method to identify injured fruit was studied. X-ray computed tomography (CT), and 1 H-MRS, applied in the medical profession and for food analyses, were investigated for this purpose. Results showed that the X-ray CT, image analyses of the MRS differentiated between normal and injured fruit. The possibility of developing a nondestructive analysis using this technology is suggested
