Abstract: Masticatory simulator refers to a mechanical device that mimics the physiological structure of human oral cavity, chewing control and functions. A masticatory simulation device has advantages of not being affected by ethics, time, or environment, and is capable of providing direct experimental verification of the dynamics of food's oral breakdown, bolus reorganization, and the release of flavor compounds. This article mainly introduces oral physiology and its simulation methods, so as to provide effective scientific basis and reference factors for the construction of masticatory simulator. At the same time, based on the principle of oral chewing, this article introduces the design principle, ideas and instrument test methods of masticatory simulator equipment applied in various fields, and focuses on the preliminary classification of existing masticatory simulator devices based on the application of equipment. It is hoped to facilitate the selection and application of masticatory simulator for researchers in different research fields.
