[Influence of super fine crushing on the extraction of polysaccharides from polystictus versicolor]
1Key Laboratory of Biochemical Engineering, Institute of Process Engineering Chinese Academy of Science, Beijing 100080.
Objective:
To study the extractive technique of Polysaccharides from Polystictus Versicolor pretreated by super fine crushing.
Methods:
Polystictus versicolor was pretreated by technique of super fine crushing, and the contrast examination of super powder (5 microm) and polystictus versicolor was done. Then the extractive technique of polysaccharides from polystictus versicolor super powder was optimized by the orthogonal design.
Results:
The extraction yield of Polysaccharides from polystictus versicolor super powder was higher 61% than that of polystictus versicolor. The optimum extractive technique of polysaccharides was 100 degrees C, 80 min and extracting 3 times.
Conclusion:
Technique of super fine crushing is propitious to the extraction of polysaccharides from polystictus versicolor.
