Embodiment 1

[0035] A production method for extracting fungus mycelium of fungus polysaccharide, characterized in that it comprises the following steps:

[0036] Step 1. Weighing the ingredients. Weigh the mushroom sticks, bean straw, bran, urea, sugar, and gypsum according to the formula. The mass ratio is:

[0037] Mushroom fungus sticks 60 servings

[0038] 30 servings of bean straw

[0039] Bran 8 servings

[0040] Urea 0.5 parts

[0041] 1 part white sugar

[0042] 0.5 parts of gypsum;

[0043] Step 2, pretreatment of the base material, first crush the mushroom sticks and bean stalks weighed in step 1 into particles with a size of 0.3 to 0.5 cm, mix the crushed mushroom sticks and bean straw, and add to the mixture Add the cellulase precursor to the mixture, the mass ratio of the cellulase precursor to the pulverized Agaricus fungus stick and bean straw mixture is 1:5, adjust the dry humidity with water, so that the water content is controlled at 40-50%. Adjust the pH to 4.5-5.5...

Embodiment 2

[0051] Step 1. Weighing the ingredients. Weigh the mushroom sticks, bean straw, bran, urea, sugar, and gypsum according to the formula. The mass ratio is:

[0052] Mushroom fungus sticks 68 servings

[0053] 20 servings of bean straw

[0054] Bran 10 parts

[0055] Urea 0.5 parts

[0056] White sugar 0.5 part

[0057] 1 part of gypsum;

[0058] Step 2, pretreatment of the base material, first crush the mushroom sticks and bean stalks weighed in step 1 into particles with a size of 0.3 to 0.5 cm, mix the crushed mushroom sticks and bean straw, and add to the mixture Add the degraded base material, the degraded base material is obtained through the base material pretreatment step in Example 1, the mass ratio of the degraded base material to the pulverized Agaricus fungus stick and bean straw mixture is 1:4 . 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 ...

Abstract

The invention discloses aproduction method of auricularia auricularmycelium for auricularia auricular polysaccharide extraction. The auricularia auricularmycelium is obtained through seven steps of weighing, base material pretreatment, mixing, bagging and sterilization, inoculation and culture, spawn running and management as well as bag removal and harvesting. Compared with the prior art, the production method has the advantages as follows: coarse lignocellulose adopting a macromolecular structure is converted into fine lignocellulose adopting a micromolecular structurethrough fermentation pretreatment of a base material, effective utilization of hyphae during culture of the mycelium is facilitated, the biological conversion and utilization rate at the culture stage of themycelium is increased to be about 70%, the culture time of the mycelium is shortened, the production efficiency is improved, the production cost is reduced, waste from industrial and agricultural production is utilized comprehensively, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of edible fungus production, in particular to a method for producing fungus mycelia for extracting fungus polysaccharides. 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] Fungus is a well-known traditional edible fungus in my country, which was first domesticated and cultivated in the world. Fungus is rich in nutrition, delicious in taste, has high health care and medicinal value, and is an important edible fungus and medicinal fungus. Fungus contains a variety of amino acids, vitamins and mineral salts and crude fiber. [0004] Modern medicine and nutrition conti...
