PROBLEM TO BE SOLVED: To obtain a highly viscous locust bean gum giving an extremely excellent aqueous solution, attaining an effect comparable or superior to conventional, locust bean gum by the addition of decreased amount of the gum, having improved water-dispersibility at a low temperature and exhibiting good workability by using a locust bean gum having a specific high viscosity. SOLUTION: This locust bean gum has a viscosity of >=2,000 mPa.s (measured by a Brookfield viscometer at 6 rpm and 25 deg.C) in the form of an aqueous solution having a locust bean gum concentration of 1.0 wt.% and forms a uniform solution without causing precipitation when the aqueous solution is left at room temperature for 1 week. The locust bean gum may have a viscosity of >=4,000 mPa.s (measured by a Brookfield viscometer at 6 rpm and 25 deg.C) in the form of an aqueous solution having a locust bean gum concentration of 1.0 wt.%. The locust bean gum is produced preferably by heating a locust bean gum having a drying loss of <=50 wt.% (measured by heating at 105 deg.C for 5 hr under normal pressure) at 80-140 deg.C. |
