Research Abstract |
A measuring method and a test equipment for the softness and the viscoelasticity property have not yet been established. The testing method which could measure the surface texture of measured object for processed food such as jelly and agar and perishable foodstuff such as pig roast and bird liver is established and the development of the functional equipment is desired. In this study, the dents was made to arise using air jet on the surface of measured object. The shape of the dents is measured in the two-dimensional laser beam. The measuring method of the softness was proposed by the measurement of diameter and depth of the dents which arose to the measured object. And the method for examining the viscoelasticity property by time course of the dents depth was proposed. The functional testing equipment based on them was manufactured and the flexible thing was measured. As a result, it was possible to show the softness at the surface area per unit load. Creep and creep recovery for the depth of the dents were clearly also obtained. Therefore, the measurement of soft measured object was possible for this measuring method, and it was possible to confirm the performance and the advantage.
