A little interaction was observed in a mixture of high galactose content guar gum (33%) or Leucaena gum (40%). The results indicated that the Figure 1. Chemical structure of carrageenans, agarose and gellan gum.
Locust bean gum and guar gum are neutral galactomannan polysaccharides of growing industrial importance. Other less important galactomannans are obtained from legume seeds—for example, alfalfa, clover, and fenugreek. The typical branched structure of these polysaccharides gives them their significant colloidal attributes with important properties for thickeners, solution stabilizers ...
Guar Gum Solutions. Guar Gum (E412) is readily soluble in cold water, forming a high viscosity solution at low concentrations which increases in viscosity as temperature rises. It is widely used for its gelling, thickening and stabilizing effect on emulsions and suspensions and often
Guar gum is approved for use in foods, pharmaceuti-cals and cosmetics. In the food industry, examples include bakeries and dairies. It is a common ingredient for dressings and sauces and as a stabilizer for drinks and juices. Guar gum serves as a thickener for sham-poos and toothpastes. It is also used in the textile and paper industries (Table 1).
Guar gum is a natural polymer used in drilling muds and fluids to flocculate drill cuttings (1,2). Guar gum, as a mudding agent, works by increasing cohesion (via thickening or gelatization) and by wrapping soil particles with a polymer bridge (2). The polymer adsorbs strongly to the soil particles (2).
