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.
