Özet

In this study, viscoelastic properties of xhantan gum (XG) and sodium alginate (SA) hydrogelling system were investigated at a definite range of volumetric mixing ratio of XG-SA in detail. The Carreau model gives reasonable fitting (R2 > 0.994) to the XG-SA system given by steady shear rheological measurements. In addition, the four element Maxwell model is used to capture well linear viscoelasticity of this system resulting from oscillatory shear rheological measurements. These measurements show that the viscoelastic relaxation times are longer for the higher ratio of XG in the hydrogel system. Physical gel network formations were also confirmed using scanning electron microscopy (SEM) of XG-SA.
