Abstract

The invention discloses a method for extracting polysaccharide from hericium erinaceus mushroom dregs. The method comprises the following steps of selecting, crushing, carrying out microwave extraction, filtering, concentrating, centrifuging, carrying out alcohol precipitation separation and drying to obtain a finished product. According to the invention, hericium erinaceus mushroom bran is developed and utilized, so that resource utilization of organic waste is realized, and environmental pollution is reduced; by extracting the polysaccharide from the hericium erinaceus mushroom bran, resource waste is reduced, and the hericium erinaceus mushroom bran as wastes turns into wealth; as the polysaccharide is extracted by adopting the hericium erinaceus mushroom bran instead of fruiting body, the production cost is greatly lowered. The method for extracting the polysaccharide from the hericium erinaceus mushroom bran by virtue of a microwave method is easy to operate, is high in extraction efficiency, is little in equipment investment, is simple in process rout and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural and sideline products and comprehensive utilization of by-products, and in particular relates to a method for extracting polysaccharides from erinaceus erinaceus chaff. Background technique [0002] With the extensive cultivation of Hericium erinaceus, a large amount of leftover mushroom chaff of Hericium erinaceus is produced. Due to the hard tissue and limited utilization, most of the chaff is discarded or burned, resulting in waste of resources and environmental pollution. [0003] After testing, it was found that the mushroom chaff contained various water-soluble nutrients such as bacterial protein, secondary metabolites, and trace elements, as well as rich organic substances. Polysaccharide is an important functional component of Hericium erinaceus, which has the functions of promoting hemolysin formation, increasing humoral immune function, anti-leukopenia, anti-aging...
