TEXTURE PROFILE OF IRRADIATED MANGOES AND PEACHES*

Abstract
The mechanical characteristics of the texture profile of Kent mango and Loring, Redskin and Suwannee peach fruits were determined. Irradiation at 150 or 300 krad as well as storage at 20°C decreased all of the measured parameters with the exception of mango cohesiveness which increased during storage. Hardness, gumminess and chewiness of irradiated Loring peaches reflected the sensory hardness ratings to a greater extent than did the puncture or shear forces.
