Guar Gum is a thickening agent derived from guar beans that has enjoyed much use in various baking applications. It is primarily used in hypoallergenic recipes that use different types of whole grain flours. Because the consistency of these flours allows the escape of gas released by leavening, guar gum is needed to improve the thickness of these flours, allowing them to rise as normal flour would.

Guar Gum, a source of dietary fiber, is derived from the Guar Bean.
