ABSTRACT:
A method and a system for a non-destructive determination of quality parameters in fresh produce. Ultrasonic sound waves are transmitted into the produce from a transducer and are received by a nearby transducer, both gripped via special arrangement cage, allowing local ultrasonic tests on the produce. Various acoustical parameters such as wave velocity and signal attenuation of the detected sound waves are analyzed in conjunction with the maturity of the sample.
