- Abstract:
- One of the most important quality indicators for fruit is the firmness which is highly correlated to the elastic modulus. This study was conducted to evaluate the potential use of ultrasonic parameters for determination of apple firmness. Ultrasonic transmission system consisted of ultrasonic pulser, two specially fabricated ultrasonic transmitting and receiving transducers for fruit, and digital storage oscilloscope. Ultrasonic parameters such as ultrasonic wave velocity, attenuation, and peak frequency were analyzed. Firmness of apple was measured by using compression test apparatus. A multiple linear regression model describing the relationship between firmness and ultrasonic parameters was proposed.
