[Study on extraction and property testing of pastern from mesona blume].
OBJECTIVE
In order to find out the pastem's content and property.


METHODS
The colloid substances-pastem 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 pastem 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.


CONCLUSIONS
This study provides the theory basis of setting quality standard of country, and helps to develop the pastem's prodution.
