The potential use of ultrasonic technique for frimness measurement of apples was evaluated . Mechanical properties and ultirasonic parameters of the apple flesh during the storage time were measured and analyzed. Ultrasonic parameters were determined from the measurement of ultrasonic wave tramsmission through the apple flesh specimen. Mechanical properties were obtained by universal testing machine. The bioyield through the apple flesh specimen. Mechanical properties were obtained by universal testing machine. The bioyield strength , rupture strength , elastic modulus, ultrasonic velocity, and the first peak frequency of the apple flesh decreased with the storage time.
