Abstract
The objective of this study was to study the effect of contact force of ultrasonic
probe on the ultrasonic attenuation and power spectrum of radish. The relationship
between attenuation(y: neper/m) and contact force(x: kgw) can be expressed as y=
a+bLnx, and the regression coefficients a and b were influenced by porosity and
volume respectively. The relationship between power spectrum and contact force
also has the same regression form, the coefficient a was influenced by porosity. The
attenuation and power spectrum respectively decreased and increased with the
increase of contact force. The correlation coefficient between physical properties of
radish and attenuation was influenced by contact force.
