Text of Abstract
Saliva plays a vital role in the human mouth health, feeling, and chewing function. 95% of the saliva is water, while the other 5% includes inorganic molecules, lipids, various proteins, and enzymes. The properties of salivary flow have been studied through bulk rheological measurements to some extent. In the present poster, we display three properties of the human saliva, including extensional rheology, dripping, and hitting on the water surface. Unlike water, all of these studies prove the viscoelasticity of saliva and the presence of amphiphilic molecules in it.
