摘要: 研究刺槐豆胶/黄原胶复配体系的流变性,并采用流变学的Cross模型进行拟合分析。结果表明:刺槐豆胶与黄原胶复配可以产生协同作用,当刺槐豆胶与黄原胶的复配体积比为4∶6时,复配体系的黏度最大,触变测试中形成的滞后环面积最大,并且在黏弹性测试中储能模量G’表现出最大值。因此,刺槐豆胶与黄原胶的最佳复配比例为体积比4∶6。对最佳比例复配体系进行不同温度处理后测试可知,最佳复配体系的最适处理温度为80 ℃,得到的复配体系黏度最大;复配体系的pH值在6.0~10.0之间时,其黏度变化较小,保持相对稳定。

Abstract: The rheological properties of locust bean gum/xanthan gum mixed systems were investigated in this paper.
Moreover, the Cross model was used to analyze their flow behavior. The results showed that locust bean gum/xanthan gum
mixed systems had synergistic effect. The system with a ratio of locust bean gum to xanthan gum 4:6 (V/V) had the highest
viscosity and largest hysteresis loop area in thixotropic test as well as the maximum storage modulus in viscoelastic test, which
suggested that the best locust bean gum/xanthan gum ratio was 4:6 in mixed systems. The optimum processing temperature that
provided maximum viscosity was 80 ℃ for the mixed system. The viscosity was almost stable when pH was between 6.0 and 10.0.

Key words: locust bean gum, xanthan gum, flow behavior, thixotropy, dynamic viscoelasticity, synergistic effect
