摘要:

流变学特性是多糖的重要性质,它间接反映了多糖的结构变化。采用黏度计测定了枸杞多糖的黏度,研究了多糖浓度、温度、热处理时间、pH 值、NaOH、抗氧化剂VC、氧化剂H2O2 以及金属离子对枸杞多糖黏度的影响。实验结果表明,多糖浓度、温度、热处理时间、pH 值、NaOH、抗氧化剂VC、氧化剂H2O2 以及金属离子对枸杞多糖黏度都有不同程度的影响。

关键词: 枸杞多糖, 黏度, 流变学特性

Abstract:

Effects of polysaccharide concentration, temperature, heat treatment time, pH, NaOH, VC, H2O2 and metallic ions on viscosity of Chinese wolfberry polysaccharides, which was measured using a viscometer, were examined in this study. Results revealed these factors could affect viscosity of Chinese wolfberry polysaccharides to differ entextent.

Key words: Chinese wolfberry polysaccharide, viscosity, rheological property
