Abstract—Viscoelastic properties of food material significantly influence the texture of diet articles. Therefore, there are some methods to measure the viscoelastic properties of food materials. However, extant methods require contact with or breakage of a food material. In this study, a novel method for measuring the viscoelastic properties of food material by using a forced vibration device is presented. In the measurement method, viscoelastic properties of food material are estimated from the amplification ratio and phase difference of food material when forced vibration is applied. The method does not require contact with a food material.
