Effects of muscle texture on ultrasonic measurements

摘要

In this study bovine n1uscle san1ples were analysed using all u1trasonic method to investigate the influence of compositional and textural characteristics on ultraso11ic measurel11el1ls. The ultritsonic method was based on the measurement of acoustic parameters (velocity, alternation and backscattering intensity) which are closely reliased to physical properties of the propagating medium. An examination of physical parameters was proposed by two types of representations: a mean profile and a parametric image. Two muscle types, which differ in composition and structure were studied. On the same samples additional measurements, mechanical resistance and chemical con1position. were performed and used to show the inference of meat composition and texture on ultrasonic data.
