Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications. [1] The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. [ 2 ]
Other sugar polymers include vegetable gums such as pectin from Citrus peel, guar gum from the guar bean, and locust bean gum from the carob bean.. Agar, alginin and carrageenan are polysaccharides extracted from algae, xanthan gum is a polysaccharide secreted by the bacterium Xanthomonas campestris, and carboxymethyl cellulose is a synthetic gum derived from cellulose.
guar gum, mannose:galactose ~2:1; tara gum, mannose:galactose ~3:1; locust bean gum or carob gum, mannose:galactose ~4:1; cassia gum, mannose:galactose ~5:1; Galactomannans are often used in food products to increase the viscosity of the water phase. Guar gum has been used to add viscosity to artificial tears, but is not as stable as ...
They contain a gelatinizing agent, also known as a thickener, that modifies their consistency, ranging from easily pourable gels to hard solids. Polyvinyl alcohol, guar gum, dextran gums, and urea-formaldehyde resins are the typical gelling agents. Guar, specifically, is a gelling agent used for the aqueous portion of the water gel explosives. [3]

Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethyl cellulose(CMC), polyanionic cellulose (PAC), or starch. In turn, deflocculants are used to reduce viscosity of clay-based muds; anionic polyelectrolytes (e.g. acrylates , polyphosphates , lignosulfonates (Lig) or tannic acid ...
Gum Senegal, gum arabic or modified guar gum thickening yield clearer and more even tints than does starch, suitable for lighter colours but less suited for very dark colours. (The gums apparently prevent the colours from combining fully with the fibers.) A printing stock solution is mostly a combination of modified starch and gum stock ...
Humans have used natural gums for various purposes, including chewing and the manufacturing of a wide range of products – such as varnish and lacquerware.Before the invention of synthetic equivalents, trade in gum formed part of the economy in places such as the Arabian peninsula (whence the name "gum arabic"), West Africa, [3] East Africa and northern New Zealand ().
