摘要: 研究了秋葵多糖溶液的黏度特性。结果表明,秋葵多糖的黏度随着其浓度的增加、温度的降低、金属离子浓度的增加而增大。pH=4时多糖溶液的黏度最高,剪切速率对其黏度的影响与其浓度相关,多糖溶液在室温下具有良好的抗降解性能。Abstract: The viscosity of okra polysaccharide was studied in the test. The results showed that viscosity of okra polysaccharide increased with the increase of its concentration, the decrease of temperature, and the increase of metal ion concentration. Moreover, pH at 4 on the viscosity of okra polysaccharide had maximum, shear rate associated with the concentration, and okra polysaccharide had better resisting degeneration ability at room temperature.
