摘要: 对pH值为5.2、粘度为51.5mPa•s的银耳溶液在不同影响因素下的粘度特性进行了研究。结果表明,增大浓度、搅拌作用、添加蔗糖,溶液的粘度升高;升高温度、热力作用、添加酸、碱、氯化钠,溶液的粘度下降。

关键词: 银耳溶液, 影响因素, 粘度特性

Abstract: The factors influencing viscidity characteristic of tremella fuciformis solution gained under pH5.2 and 51.5mPa•shave been discussed qualitatively. The results showed that firstly the viscosity of extract increases with the increasing of itsdensity; secondly heating can destroy the structure of tremella fuciformis polysaccharide in some degree; thirdly the change ofpH value would lead up to both the degradation of tremella fuciformis polysaccharide decomposed and the decrease of theviscosity of extract; fourthly shearing action can play an important role in improving the viscosity of extract; finally adding canesugar increase the viscosity of extract, while adding NaCl decrease that.

Key words: tremella fuciformis solution, influencing factor, viscidity characteristic
