刺槐豆胶的流变性研究

Study on The Reology of Robinia bean gum

对刺槐豆胶的流变性进行了研究。研究结论表明:刺槐豆胶的粘度随浓度的升高而升高,当浓度为2%时,其粘度为46.4MPa.s;刺槐豆胶为非牛顿流体,其粘度随切变速度的增加而降低;小于80℃加热时可使刺槐豆胶的粘度增加,60℃为刺槐豆胶的最佳加热温度;冷冻对刺槐豆胶溶液的粘度没有影响,而冷藏可使刺槐豆胶的粘度有所下降;pH对刺槐豆胶溶液的粘度影响不大,即刺槐豆胶在酸性溶液和碱性溶液中较为稳定;刺槐豆胶与黄原胶无协效性。

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.
