| titleOfInvention | Method for preparing high-purity agaricus blazei murrill polysaccharide |
| abstract | The invention discloses a method for preparing a high-purity agaricus blazei murrill polysaccharide and provides a method capable of obtaining high content of the agaricus blazei murrill polysaccharide and suitable for large-scale production. The method comprises the following steps of: adding cellulase and pectinase to an agaricus blazei murrill powder; after adding water to the agaricus blazei murrill powder and uniformly stirring the water and the agaricus blazei murrill powder, regulating the pH value of a mixture to 6.0+/-0.1; performing enzymolysis on the mixture for 40 minutes; carrying out microwave extraction on the mixture; freezing and drying agaricus blazei murrill water extract so as to obtain a concentrated product; carrying out decolorizing and primary impurity removal treatment on an agaricus blazei murrill polysaccharide extract solution by using a macroporous adsorbing resin; and then carrying out deproteinization treatment on the agaricus blazei murrill polysaccharide extract solution by using an ion exchange resin; further purifying the agaricus blazei murrill polysaccharide after deproteinization by using an ultrafiltration technology, so as to eliminate micromolecular water soluble substances; pre-freezing an agaricus blazei murrill polysaccharide ultrafiltrate to -60 DEG C; maintaining the agaricus blazei murrill polysaccharide ultrafiltrate at -60 DEG C for at least 4 hours; and drying the agaricus blazei murrill polysaccharide ultrafiltrate at -45 DEG C in a vacuum state so as to obtain the agaricus blazei murrill polysaccharide. Through the adoption of a microwave synergistic complex enzyme method, a resin deproteinization technology, an ultrafiltration process purification and freeze-drying technology, which are combined with each other, the purity of the agaricus blazei murrill polysaccharide reaches 90%. |
