Guar gum is derived from the endosperm of guar beans. The seeds of the Guar plant consists of three main parts – the germ, the endosperm and the husk. Guar gum is processed by removing the husk, followed by milling and filtering to produce a slightly yellow powder that has a good flow. Guar gum is also economical because it has a better the water- thickening ability than other agents (e.g. cornstarch) and only a small quantity is needed for producing sufficient viscosity. It is useful as a thickening agent, emulsifier and stabiliser.
