Abstract: Dysphagia has become a serious health issue that our society is facing today. Thickened liquids can effectively reduce the risk of aspiration pneumonia for dysphagic patients and are therefore widely used in the treatment and nursing of those patients. The appropriate application of thickened liquids is closely related to their rheological properties; therefore, rheology has become an important research topic in the design and manufacturing of dysphagia foods. In this paper, we review the state of the art in this research area. The rheology of thickened liquids and the existing methods for measuring their effectiveness are reviewed and the factors affecting the rheological properties of thickened liquids are elucidated. The difference and matching between the rheological properties of videofluoroscopic contrast agents and thickened liquid foods and the oral rheological discrimination of thickened liquids are also discussed. Our aim is to provide a theoretical basis and technical guidance for the development and production of thickened liquid foods in China.
