Embodiment 1

[0016] 1) Material pretreatment: select 20 g of Hericium erinaceus fruiting bodies, crush them, pass through a 30-mesh sieve, add 300 ml of water to soak for 1 hour, and wait for extraction;

[0017] 2) Microwave extraction: adjust the power of the microwave generator to 300w, carry out microwave treatment on the above-mentioned pretreated extraction material for 8 minutes, filter, carry out solid-liquid separation, and prepare to concentrate the supernatant after discarding the solid;

[0018] 3) Concentration: put the collected supernatant in a rotary evaporator, concentrate under reduced pressure at 40°C, and concentrate to 1 / 4 of the original volume;

[0019] 4) Alcohol precipitation: Stir and mix the concentrated solution and 70% edible ethanol at a ratio of 1:3. Since the polysaccharide is insoluble in ethanol, a precipitate is formed and precipitates at the base of the container;

[0020] 5) Centrifugation: After the concentrated solution-ethanol mixture was placed in t...

Embodiment 2

[0024] 1) Material pretreatment: select 20 g of Hericium erinaceus fruiting bodies, crush them, pass through a 40-mesh sieve, add 400 ml of water to soak for 2 hours, and wait for extraction;

[0025] 2) Microwave extraction: the power of the microwave generator is selected as 450w, and the above-mentioned pretreated extraction material is subjected to microwave treatment for 6 minutes, centrifuged, and solid-liquid separation is performed, and the supernatant is prepared to be concentrated after discarding the solid;

[0026] 3) Concentration: put the collected supernatant in a rotary evaporator, concentrate under reduced pressure at 55°C, and concentrate to 1 / 4 of the original volume;

[0027] 4) Alcohol precipitation: Stir and mix the concentrated solution and 95% edible ethanol at a ratio of 1:1.5. Since the polysaccharide is insoluble in ethanol, a precipitate is formed and precipitates at the base of the container;

[0028] 5) Centrifugation: After the concentrated solut...

Embodiment 3

[0032] 1) Material pretreatment: select 20 g of Hericium erinaceus fruiting bodies, crush them, pass through a 60-mesh sieve, add 500 ml of water to soak for 4 hours, and wait for extraction;

[0033] 2) Microwave extraction: the power of the microwave generator is selected as 600w, and the above-mentioned pretreated extraction material is subjected to microwave treatment for 4 minutes, filtered, and solid-liquid separation is performed, and the supernatant is concentrated after discarding the solid;

[0034] 3) Concentration: put the collected supernatant in a rotary evaporator, concentrate under reduced pressure at 70°C, and concentrate to 1 / 4 of the original volume;

[0035] 4) Alcohol precipitation: Stir and mix according to the ratio of 1:1 between the concentrated solution and 100% edible ethanol. Since the polysaccharide is insoluble in ethanol, a precipitate is formed and precipitates at the base of the container;

[0036] 5) Centrifugation: After the concentrated solu...

Abstract

The invention discloses an extracting process for a hedgehog hydnum polysaccharide. The extracting process comprises the following technological steps: raw material pretreatment, microwave extraction, concentration, alcohol deposition, centrifugation, drying, preservation, and the like. The microwave extraction method saves the extraction time and improves the efficiency. The extract has the functions of immunoregulation, tumor resistance, ageing resistance, blood fat reduction, blood sugar reduction, mutation resistance, radiation protection, and the like.

Description

technical field [0001] The invention relates to a method for extracting polysaccharides, in particular to a process for extracting Hericium erinaceus polysaccharides. Background technique [0002] Hericium erinaceus belongs to the phylum Fungi and the family Hericiumaceae. Hericium erinaceus is a well-known edible and medicinal fungus. It tastes delicious when eaten. Since ancient times, there has been a saying of "hericium erinaceus, seafood bird's nest". It has always kept pace with bear's paw, sea cucumber and shark's fin. It is the four famous treasures in the world, and it has unique medicinal value. Traditional Chinese medicine believes that Hericium erinaceus is flat in nature and sweet in taste, which can help digestion and benefit the heart. The most important active substance of Hericium erinaceus is Hericium erinaceus polysaccharide. According to the data query, Hericium erinaceus polysaccharide has immune regulation, anti-tumor, anti-aging, lowering blood fat, ...
