Summary:There have been few reports on test methods for viscoelasticity properties of soft samples using an air jet instead of plungers for loading and unloading. Authors propose a method of evaluating their viscoelasticity properties, such as soft processed foods and industrial products, using the air jet with newly developed test equipment. In this method, loading and unloading can be performed using the air jet in a very short time, loading time can be arbitrarily set, and the shape of the dents formed on the surface of soft samples can be instantaneously measured using light from a semiconductor laser. Using the developed equipment, authors measured the shape of the dents formed on soft samples, measured the depth of the dents for various loading times, types of soft samples and pressures, and evaluated the viscoelasticity properties of the soft samples with respect to elastic compliance and equivalent dent depth.
