Guar gum is primarily the ground endosperm of the seeds from cyamopsis tetragonolobus. The guar seeds are dehusked, milled and screened to obtain the guar gum. It is typically produced as a free flowing, pale off-white colored, coarse to fine ground powder. Guar gum is extracted from the guar bean where it acts as a food and water store. Guar gum is more soluble than locust bean gum and is a better emulsifier as it has more galactose branch points. It is a water soluble fiber that acts as a bulk forming laxative. Guar gum and micellar casein mixtures can be slightly thixotropic if a biphase system forms.
