Extensional and shear rheology of okra polysaccharides in the presence of artificial saliva

ARTICLE OPEN Extensional and shear rheology of okra polysaccharides in the presence of artificial saliva Bo Yuan 1 , Christos Ritzoulis 1,2 and Jianshe Chen1 Extensional and shear viscosities were studied for mixtures comprising artificial saliva and okra mucilage, the latter acting as a model thick-liquid food. These experiments aimed to obtain information on the flow-behavior information of the systems, underpinning the texture sensation of foods as perceived by dysphagic and xerostomic...
