沙蒿胶冷水溶部分和热水溶部分流变性研究

The rheology of cold water and hot water dissolving sections of Artemisia seed gum

研究了沙蒿胶冷水溶和热水溶部分的流变性,沙蒿胶溶于冷水和热水中,其流变性有所不同。考察了浓度、温度、剪切力、pH、冻融等参数对沙蒿胶粘度的影响。沙蒿胶与瓜尔豆胶、黄原胶、海藻酸钠具有明显的协效性,与卡拉胶、壳聚糖、决明子胶、魔芋粉无协效性。

The rheology of hot water and cold water dissolving parts of Artemisia gum was discussed, respectively. The results showed that the viscosity of Artemisia gum was affected by concentration,temperature, shearing, pH, freezing-thawing etc. Artemisia gum was highly synergic with guar gum, xanthan gum, algimic acid; Artemisia gum was not synergic with carrageenan, chitosan, cassia gum, Konjac flour. The rheology of Artemisia gum dissolved in hot water was different in comparison with that dissolved in cold water.
