| Abstract: | A high-frequency (1 MHz) ultrasonic device was applied to investigate the relationships
between the somatic cell count (SCC) in milk and the physical properties measured through
the changes in the velocity and attenuation of wave propagation during gelation formation in
the California mastitis test (CMT). Owing to nonhomogenous mixing without shear applied
in CMT gelation, ultrasonic signals were more unstable than those under a complete mixing
condition. On the basis of the complete mixing condition, the velocity had no significant
relationship with SCC concentration; however, there was a clearly positive relationship between
attenuation and SCC concentration. In addition, the linear fitting slopes of attenuation during
the measurement were positive as the SCC concentration was less than the threshold value
(SCC = 5 × 104 cells/ml). In contrast, the slopes became negative. |
