Water soluble seed polysaccharides have a variety of applications in the Food Industry. They serve as viscosity modifiers, gelling agents, texturizers, binders and sugar/ice crystal growth inhibitors; polysaccharides from plants such as guar and locust bean are widely applied industrially because of their viscous characteristics. Brachystegia eurycoma belongs to the family Leguminosae. The use of Brachystegia eurycoma is currently limited to local culinary uses despite promising characteristics of the polysaccharide component of the seed; there is very little information on the properties of the polysaccharide which would stimulate expansion in its applications. In this investigation the researchers report on the seed composition, gum yield, molecular characteristics, and effect of temperature and small angle deformation on the properties of the seed polysaccharide.
