Embodiment Construction

[0025] Such as figure 2 Shown, the Pleurotus eryngii superfine powder polysaccharide extraction process comprises the following steps:

[0026] (1) Coarse pulverization: remove surface impurities and hard root parts of Pleurotus eryngii raw material, carry out preliminary pulverization to raw material with cyclone pulverizer, cross 100 mesh sieves;

[0027] (2) Superfine pulverization: the coarse powder obtained in step (1) is subjected to airflow superfine pulverization, and the average particle size of the powder is 150 μm, then dried to constant weight in a vacuum drying oven, and sealed for storage;

[0028] (3) Degreasing: polysaccharides are polar macromolecular compounds, which will affect the purity of polysaccharides in follow-up tests, so the powder needs to be degreased; the superfine powder in step (2) is used in a large Soxhlet extractor, with a boiling point of 60 degrees Petroleum ether to remove lipophilic components;

[0029] (4) Neutral water extraction: E...

Abstract

The invention relates to a process for extracting pleurotus eryngii submicron powder polysaccharides. The process comprises the following steps of carrying out coarse grinding, carrying out ultramicro grinding, carrying out degreasing, carrying out neutral water extraction, carrying out deproteinization, carrying out decolorization, carrying out alcohol precipitation, carrying out dialysis and carrying out concentrating and drying so as to obtain required coarse polysaccharides, wherein residues remaining after the step of carrying out neutral water extraction step are subjected to alkali extraction, and the steps, i.e., carrying out deproteinization, carrying out decolorization, carrying out alcohol precipitation, carrying out dialysis and carrying out concentrating and drying are repeated so as to obtain coarse polysaccharides which are the same as the required coarse polysaccharides. According to the process, the extraction ratio of the polysaccharide product is obviously increased, and the extracted submicron powder polysaccharides have an obviously-improved blood fat reducing effect and play roles in remarkably decreasing total cholesterols, extremely remarkably decreasing triglycerides and extremely remarkably increasing high-density lipoproteins.

Description

technical field [0001] The invention relates to the technical field of extracting polysaccharides from Pleurotus eryngii, and specifically discloses a process for extracting polysaccharides from Pleurotus eryngii superfine powder. Background technique [0002] The separation, purification and activity of Pleurotus eryngii polysaccharide has always been a hot spot in research and product development at home and abroad. Due to the different requirements for product purity and activity, it can lower blood sugar, blood fat, antithrombotic, anti-radiation, clear lung, improve immunity, beautify and The effect of weight loss is also different, and the methods used are also different. [0003] At present, the existing technical solutions for the separation and purification of Pleurotus eryngii polysaccharide mostly use water-soluble alcohol precipitation method, and the general process is as follows: figure 1 As shown, the yield of Pleurotus eryngii crude polysaccharide prepared b...
