【Abstract】 Agaricus blazei murrill polysaccharide was extracted by UF.Centrifugal pretreatment technology is simply and feasible.Because the 80 thousand molecular retention tube fiber ultrafiltration made of PVDF is better anti-fouling and easy to clear,it is much more suited to the study.The results show that at room temperature,the UF pressure is 0.08-1.0 MPa,polysaccharide can be condensed to 35g·L^-1.The purify of polysaccharide product dried under lower temperature is 78.4% and the recovery is 76.36%.更多还原
