Ultrasonic testing of the time evolution properties of oranges

Abstract

Valencian region in Spain is one of the greater producers of citrus fruits of the world. In this context, the capability to obtain information related to the quality of the fruit is costly and destructive. The quality and evolution with the storage time of the fruits properties inside the refrigeration chambers can be tested by means of the use of ultrasounds. In this study we report the techniques, experimental set up, measurement procedures and results obtained to relate classical measurements (destructive) with the ultrasonic ones, in order to test the possibility to design a non-destructive ultrasonic device able to give information as turgidity and hydration of the oranges.
