| Research Abstract |
Glactomannan polysaccharides are existed from bean plant seeds. Galactomananas are made for industrial, because they are low costs and high viscosity. Galactomannan polysaccharides is consists of a mannose backbone and galactose side chains. Guar gum, tara gum and locust bean gum are categolized as galactomannan polysaccharides. A difference between the three gums is the galactose/mannose ratio. Guar gum forms liquid crystalline structure. Locust bean gum forms hydrogels by freezing and thawing. In this study, galactomannan having various side chains are mixed with other polysaccharides from various plants and hydrogelation by synergistic effect. Higher order structure of hydrogels is measured by differential scanning calorimetry (DSC) and water retention is investigated.
