Abstract: In the paper we mainly discussed the reology of Robinia bean gum.The result showed that the viscosity of Robinia bean gum rised with the rising of concentration.When is concentration reached to 2%,viscosity was 46.4MPa.s.Its viscosity rised with the rising of the temperature and 60℃ was the optimum temperature of heating up.The effect of both freezing-thawing and pH chang was small. It had no synergsm with xanthan gum.
