Guar gum shows high low-shear viscosity but is strongly shear-thinning. It is very thyrotrophic above concentration 1%, but below 0.3% the thixotropy is slight. It has much greater low-shear viscosity than that of locust bean gum, and also generally greater than that of other hydrocolloids. Guar gum shows viscosity synergy with xanthan gum. Guar gum and micellar casein mixtures can be slightly thyrotrophic if a biphase system forms.
