Guar Gum is a white flour-like substance made from an East Indian seed. Use small amounts as a thickener, binder, and volume enhancer. Guar gum powder 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. It is especially useful as a binder in gluten-free baking. Guar gum is not just a thickening agent, but a binder and plasticizer as well. When untreated ice cream melts and refreezes, grainy ice crystals often form. This substance has the natural ability to bind with water molecules, preventing them from forming the unwanted crystals. Processed foods with creamy textures are primarily held together with binders such as this. Without a binder, the individual ingredients might separate into a watery mess.
