Abstract
This paper reports the propagation and the attenuation of sound waves in crude palm oil (CPO) refined bleached deodorized (RBD) palm oil palm olein and some other vegetable oils: coconut oil corn oil and soyabean oil. The ultrasonic pulse echo overlapped technique has been employed to obtain the ultrasonic properties of the oils from room temperature up to 90 degrees C. The velocity of sound in vegetable oil products decreases linearly with temperature while their ultrasonic attenuation (alpha) decreases exponentially with temperature. By using an MBS 8040 ultrasonic analyzer we observed that alpha/f2 decreases nonlinearly with frequency (f) which is mainly due to a relaxation process. The ultrasonic properties of the oils are very dependent on their viscosity density and molecular structure. The ultrasonic wave velocity and attenuation coefficient can be used as a basic tool to identify Malaysian palm oil
