Problems solved by technology

Although the alkali treatment increases the polysaccharide content, the alkali extraction method is easy to hydrolyze some polysaccharides, destroying the active structure of polysaccharides and reducing the yield of polysaccharides
At the same time, it is difficult to neutralize the desalination process
[0013] Enzymatic hydrolysis extraction method has many advantages such as simple process and time saving, but the price of enzyme is high and the conditions of use are relatively harsh

Embodiment 1

[0045] Comprehensive extraction of embodiment 1 fungus polysaccharide

[0046] The extraction process of fungus polysaccharides is as follows: figure 1 shown.

[0047] The comprehensive extraction method of fungus polysaccharide is:

[0048] 1. Dry the fruiting body of the fungus, pick out the impurities, weigh the feeding amount, wash with water to remove the sediment, then add 10 times the amount of water, heat to 60 degrees and soak for 6 hours. Turn to the refining post.

[0049] 2. Use a refiner to refine the soaked and fully expanded fungus with water to make a uniform slurry. Switch to filter position.

[0050] 3. First install the press filter with 80-mesh steel mesh, squeeze and filter, and then change to 150-mesh steel mesh for extrusion and filtration, separate the filter residue and filtrate, the filtrate is concentrated under reduced pressure, and the filter residue is transferred to the extraction post.

[0051] 3.1 Concentrate the filtrate under reduced pre...

Embodiment 2

[0067] Comprehensive extraction of embodiment 2 fungus polysaccharide

[0068] The comprehensive extraction method of fungus polysaccharide is:

[0069] 1. Dry the fruiting body of the fungus, pick out the impurities, weigh the feeding amount, wash with water to remove the sediment, then add 20 times the amount of water, heat to 50 degrees and soak for 8 hours. Turn to the refining post.

[0070] 2. Use a refiner to refine the soaked and fully expanded fungus with water to make a uniform slurry. Switch to filter position.

[0071] 3. First install the press filter with 80-mesh steel mesh, squeeze and filter, and then change to 150-mesh steel mesh for extrusion and filtration, separate the filter residue and filtrate, the filtrate is concentrated under reduced pressure, and the filter residue is transferred to the extraction post.

[0072] 3.1 Concentrate the filtrate under reduced pressure:

[0073] Turn on the vacuum pump and the circulating water cooling pump. When the v...

Embodiment 3

[0085] Comprehensive extraction of embodiment 3 fungus polysaccharide

[0086] The comprehensive extraction method of fungus polysaccharide is:

Abstract

The invention relates to extraction of active ingredients of Chinese medicines, in particular to a comprehensive extraction process for auricularia auricula polysaccharide. In the comprehensive extraction process for the auricularia auricula polysaccharide, the auricularia auricula polysaccharide is extracted by cooperating a super micron-milling technology, ultrasonic waves and complex enzyme, the dissolution rate of the auricularia auricula polysaccharide can be greatly improved by combining specific extraction process conditions, and the comprehensive extraction process has the advantages of short reaction time, mild reaction conditions, thorough breaking of cell walls, and high dissolution rate of the polysaccharide. Through comprehensive research, the comprehensive extraction process is easy to operate, and ensures that ingredients are retained comprehensively and the extraction yield is greatly improved.

Description

technical field [0001] The invention relates to the extraction of active ingredients of traditional Chinese medicines, in particular to a comprehensive extraction process of fungus polysaccharides. Background technique [0002] 1. Fungus [0003] Fungus, also known as black fungus, light fungus. Mycological classification belongs to Basidiomycetes, Auricularia, Auriculariaceae, edible fungus of the genus Auricularia (scientific name: Auriculariaor Wood ear), fruiting body gum, disc-shaped, irregular ear shape, 3-12 cm in diameter. Soft when fresh, horny when dry. It has a delicate taste and a special flavor. It is a well-known edible fungus rich in nutrition. Mainly distributed in Heilongjiang, Jilin, Fujian, Taiwan, Hubei, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan and other places. It grows on the rotting wood of more than 120 kinds of broad-leaved trees such as oak, poplar, banyan, and locust tree, solitary or in groups. At present, artificial cultivation is mainly...
