Guar gum is a thickener derived from seeds of a legume native to South Asia.[1][2][3][4]

Characteristics

[edit | edit source]

The gum is sold as a beige powder. It can be hydrated in cool water,[3] whereupon it will bind up to 100-fold its weight of water and impart high viscosity to the mixture.[4][5] However, it cannot actually make gels without other additives.[3] Notably, this viscous mixture is not particularly stable in highly acidic mixtures (< pH 4).[4][5] The gum can sometimes result in an undesirable starchy texture.[1]

Selection and storage

[edit | edit source]

Make sure to purchase food-grade guar gum, since non-food grades exist. Keep guar gum in an airtight container away from light, heat, and moisture.

The water-binding capacity of guar gum makes it particularly useful in gluten-free baking and frozen desserts. In the former, it adds structure and functions as a binder;[6] in the latter, it reduces the development of ice crystals.[3] It also adds body and mouthfeel to products where a creamy texture is desired.[3][4]

Substitution

[edit | edit source]

In some cases, xanthan gum may act as a substitute for guar gum.[1]
