1The third affiliated hospital of Sun Yat-sen university, Guangzhou 510630, China.
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.
Conclusion:
This study provides the theory basis of setting quality standard of country, and helps to develop the pastem's prodution.
