Embodiment 1

[0025] A kind of production method of the mushroom mycelium that is used to extract lentinan, is characterized in that comprising the following steps:

[0026] Step 1, weigh the material, weigh the mushroom sticks, corncobs, bran, urea, white sugar, superphosphate and gypsum according to the formula, and the mass ratio is:

[0027]

[0028]

[0029] Step 2, pretreatment of the base material, first crush the shiitake mushroom sticks and corn cobs weighed in step 1 into 0.3-0.5cm sized particles, mix the shredded shiitake mushroom sticks and corn cobs, and add to the mixture Add the cellulase parent matter in the mixture, the mass ratio of the cellulase parent matter to the pulverized shiitake mushroom stick and corn cob mixture is 5%, adjust the dry humidity with water, and control the water content at 40-50%, and use acetic acid Adjust the pH to 4.5-5.5, mix well, put it into the cement pool and smooth it gently, keep the material plane 20-30cm lower than the pool mouth,...

Embodiment 2

[0036] Step 1, weigh the material, weigh the mushroom sticks, corncobs, bran, urea, white sugar, superphosphate and gypsum according to the formula, and the mass ratio is:

[0037]

[0038] Step 2, pretreatment of the base material, first crush the shiitake mushroom sticks and corn cobs weighed in step 1 into 0.3-0.5cm sized particles, mix the shredded shiitake mushroom sticks and corn cobs, and add to the mixture Add the base material after degradation, the base material after degradation is obtained through the base material pretreatment step in embodiment 1, the mass ratio of the base material after degradation and the mixture of shiitake mushroom sticks and corncobs after crushing is 20%. Adjust the dry humidity with water to control the water content at 50%, adjust the pH to 4.5-5.5 with acetic acid, mix well, put it into the cement pool and smooth it with light pressure, keep the material level 20-30cm below the pool mouth, cover with plastic film, Vents are left at t...

Abstract

The invention discloses a production method for extracting mushroom mycelium of lentinan. The mushroom mycelium is obtained by the following seven steps: weighing materials; pretreating base materials; mixing; bagging and sterilizing; inoculating and cultivating; carrying out spawn running management; removing a bag and harvesting. Compared with the prior art, the production method disclosed by the invention has the advantages that through fermentation pretreatment on the base materials, coarse lignocellulose with a macromolecular structure is transformed into fine lignocellulose with a micromolecular structure; effective utilization of hyphae during cultivation of the mycelium is facilitated; the biotransformation utilization rate of the mycelium at the cultivation stage is increased, and reaches about 70%; the cultivation time of the mycelium is shortened; the production efficiency is improved; the production cost is reduced; comprehensive utilization of waste in industrial and agricultural production is achieved; the environment is protected.

Description

technical field [0001] The invention relates to the technical field of edible fungus production, in particular to a production method of mushroom mycelia for extracting lentinan. Background technique [0002] Edible fungi are recognized as healthy food or functional food in the world due to their rich nutrition. They are not only rich in protein and vitamins, but also contain physiologically active substances, such as high molecular polysaccharides, natural organic germanium, cAMP, triterpenoids, etc. The immune function of the human body has important value. [0003] Lentinus edodes is a well-known traditional edible fungus in my country, which was first domesticated and cultivated in the world. Lentinus edodes is rich in nutrition, delicious in taste, and has high health care and medicinal value. It is regarded as the "king of mushrooms" and is an important edible and medicinal fungus. Shiitake mushrooms contain more than 10 kinds of amino acids, including 7 kinds of ess...
