ABSTRACT Acoustical, mechanical, and quality parameters of ripe winter-grown melons were tested in sample fruit sectors from different depths, and the relationships among them were analyzed. The modulus of elasticity and the tangent modulus of the sample tissues decreased ckastically with the sample depth; the acoustical attenuation of a transmitted pulse, as well as the quality characteristics tested in this study, strongly increased with the depth of the fruit sample. This strong dependence on depth (R = 0.842) indicates the potential for using the attenuation coefficient for the identification of internal fruit quality. Wave propagation velocity was found to be a poor predictor for internal properties of ripe winter grown melons.
