Abstract
The galactose/mannose ratio of guar gum, guar gum treated with purified ${\alpha}$-galactosidase and locust bean gum were investigated. Gel-promoting property of enzyme-treated guar gum increased when the galactose/mannose ratio was about 1 : 3.2, which was close to the ratio of 1 : 3.3 for locust bean gum. And the ratio was obtained when the guar gum was hydrolyzed by the enzyme for 24 hr. It is clear that enzymatic depletion of galactose from guar gum by sunflower seed ${\alpha}$-galactosidase would lead to a significant increase in gelation ability. The mixture of xanthan gum and guar gum, and xanthan gum, guar gum and enzyme-treated copra meal were also investigated in viscosity behavior.
