Abstract

The invention relates to a method for extracting polysaccharide from hericium erinaceus spore powder, which comprises the following steps: (1) soaking the hericium erinaceus spore powder in a sodium chloride aqueous solution to ensure that sodium chloride fully enters the spore powder to obtain pretreated spore powder; and (2) immersing the pretreated spore powder into deionized water to obtain the swelled spore powder. And (3) freeze-drying the swelled spore powder, and crushing to obtain the wall-broken spore powder. And (4) heating the wall-broken spore powder in water, carrying out ultrasonic extraction, carrying out solid-liquid separation after the extraction is completed, and respectively collecting a to-be-extracted solution and solid residues. And (5) adding a modified adsorbent into the to-be-extracted solution to perform decoloration treatment, then performing solid-liquid separation after decoloration treatment is completed, and sequentially performing alcohol precipitation separation and drying treatment on the obtained decoloration solution to obtain a hericium erinaceus spore powder polysaccharide product. According to the method disclosed by the invention, the wall breaking effect on the hericium erinaceus spore powder is effectively improved by adopting the characteristics of the freeze-drying technology, the decoloration treatment is also realized, and the purity and quality of the extracted polysaccharide substance are improved.

Description

technical field [0001] The invention relates to the technical field of Hericium erinaceus spore powder processing, in particular to a method for extracting polysaccharides from Hericium erinaceus spore powder. Background technique [0002] When Hericium erinaceus grows to a late stage, it will eject spore powder as a seed for propagation. These spore powders develop and form Hericium erinaceus in a suitable environment, so that Hericium erinaceus continues to continue. Hericium erinaceus spore powder contains various active substances such as Hericium erinaceus polysaccharides, which have high nutritional value and medicinal efficacy. Studies have shown that erinaceus erinaceus polysaccharides have obvious anti-complement activity and promote lymphocyte proliferation, which can improve the body's immunity. force plays an important role. [0003] Extraction of Hericium erinaceus spore powder is an effective way to obtain polysaccharide components. However, during the extrac...
