description The invention relates to a method for extracting polysaccharide from pleurotus eryngii mushroom bran and relates to an efficient production technology of pleurotus eryngii mushroom bran polysaccharide. The method for extracting polysaccharide from pleurotus eryngii mushroom bran comprises the following steps: preparing fungi bags, selecting, crushing, carrying out steam explosion, extracting with warm water, centrifuging, precisely filtering, carrying out ultra-filtration concentration, carrying out alcohol precipitation, centrifuging and carrying out spray drying to obtain a finished product. By virtue of the method for extracting polysaccharide from pleurotus eryngii mushroom bran, the cell walls of hyphae are broken by steam explosion; the hypha polysaccharide is extracted by warm water; compared with the hot-water extraction method of polysaccharide in the prior art, the method is high in polysaccharide extraction efficiency and low in energy consumption and supplies a novel approach to high-valued utilization of the mushroom bran.
