specific Embodiment approach 1

[0006] Specific embodiment one: In this specific embodiment, a method for extracting black fungus polysaccharide is characterized in that the steps of the method for black fungus polysaccharide extraction are as follows: 1. Extraction of black fungus polysaccharide: firstly carry out screening of black fungus, select fresh autumn Picked black fungus, dried and pulverized, added black fungus powder and aqueous solution at a ratio of 1g: 25mL to 1g: 40mL, and extracted with a strong electric field for 40 to 60 minutes to obtain an extract containing black fungus polysaccharides, and finally used The decanter centrifuge performs solid-liquid separation at a speed of 1500-2000r / min, separates the extract and residue, then adds the residue into the aqueous solution at a ratio of 1g:25mL to 1g:40mL, and continues the strong electric field extraction and centrifugal separation, continuous extraction 3 times, remove the residue, and combine the extracts. 2. Concentration: Concentrate ...

specific Embodiment approach 2

[0007] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 1, the extraction electric field strength is 60-90 kV per square centimeter, the high-voltage electric field pulses are 600-800 times, and the pulse frequency is 300-500 Hz. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0008] Embodiment 3: This embodiment is different from Embodiment 1 in that it is characterized in that the solid content in the concentrated solution in step 2 is 50% to 70%. Others are the same as in the first embodiment.

Abstract

A blackfungus polyhexose extraction method relates to a Blackfungus polyhexose preparation method. The invention solves the problems of low extraction rate, low activity and fussy production technique existing in extracting the blackfungus polyhexose with the existing traditional method. The technical steps of the blackfungus polyhexose extraction method are as follows: blackfungus is selected, sliced and cracked, and is extracted by a strong electric field; then a supercentrifuge is used for separating the extraction liquid and removing the protein and lipid materials, and then a vacuum scraper type film is used for concentrating, and a vacuum freezedryer is used for freeze-drying, thus obtaining the freeze-dried powder of the blackfungus polyhexose. The blackfungus polyhexose prepared by the invention is a natural extract, does not have side effects on the human bodies, and has the functions like increasing the immunologic function, resisting knubs, reducing blood-fat and blood pressure, resisting cruor and thrombus, losing weight, caring beauty and skin, and the like. The blackfungus polyhexose can be broadly applied in the fields like food, health products, cosmetics, medicines, biochemical industry, and the like.

Description

technical field [0001] The invention relates to a preparation method of black fungus polysaccharide. Background technique [0002] Black fungus polysaccharide is a special active factor of black fungus, which has the functions of enhancing immune function, anti-tumor, lowering blood fat, lowering blood pressure, anti-coagulation, anti-thrombosis, weight loss, beauty and skin care. It can be used in food, health products, cosmetics, medicine, biochemical and other fields. [0003] At present, black fungus polysaccharide can be widely used in the production of food, medicine, health care products, and cosmetics. It is a worldwide multifunctional product popular in Europe, America, Japan, and Korea, and its market prospect is very broad. Although there are many studies on black fungus polysaccharides, the extraction methods of black fungus polysaccharides are mainly ultrasonic method and reflux extraction method. A large number of free radicals will be generated during the ext...
