摘要
目的:了解中药仙草的仙草胶含量及其胶性能情况。方法:用高压高温提取的方法从两种仙草中提取出仙草胶,测定其特性粘度、质构性、含量并进行比较。结果:两种仙草中胶质平均含量为30.55 g/100 g;仙草胶特性粘度平均为85.01 ml/g;与木薯淀粉混合胶比较的硬度系数、弹性系数、内聚力系数分别为23.71、1.128、0.431,其中直立型仙草的各项指标均低于匍匐型仙草。结论:仙草有作为食品用粘稠剂的开发价值,本研究为仙草的质量标准制订以及仙草胶产品开发提供了参考依据。
Objective： In order to find out the pastern＇s content and property. Methods： The colloid substances-pastern were extracted from the grass with high pressure and high temperature and then were compared. Results： The pastem＇s average content was 30. 55 g/100 g. The average intrinsic viscosity of pastern was 85.01 ml/g. Using the cassava starch complex gums as a standard reference, the coefficient of hardness, elastic coefficient and coefficient of cohesion were 23.71,1. 128,0. 431, respectively. Conclusion： This study provides the theory basis of setting quality standard of country, and helps to develop the pastem＇s prodution.
