Embodiment 1

[0014] 1. Add water to 1 ton of Polygonum cuspidatum dregs until the water content is 65%, add compound enzyme preparation of 0.09% by weight of Polygonum cuspidatum medicinal residue, mix well, ferment and enzymatically hydrolyze at room temperature for 48 hours. In the compound enzyme preparation, cellulase accounts for 65% with an enzyme activity of 20,000 units, and the rest is pectinase with an enzyme activity of 18,000 units.

[0015] 2. Add 1.2% quicklime, 1% gypsum, 1.1% sucrose, 18% cottonseed hulls, and 10% wheat bran to the total weight of treated Polygonum cuspidatum dregs, and mix well to obtain a culture medium for edible fungi.

[0016] The edible fungi culture medium obtained through the above treatment, wherein the mass fraction of resveratrol is 0.12%, the mass fraction of crude protein is 6.58%, the mass fraction of nitrogen-free extract is 31.52%, and the mass fraction of crude fiber is 32.45%, all according to the edible fungus culture medium. dry weight m...

Embodiment 2

[0018] 1. Add water to 1 ton of Polygonum cuspidatum medicinal residues until the water content is 68%, add 1.1 kg of compound enzyme preparation and mix well, then ferment and enzymatically hydrolyze at room temperature for 60 hours. Cellulase accounts for 70% of the compound enzyme preparation, with an enzyme activity of 22,000 units, and the rest is pectinase, with an enzyme activity of 19,000 units.

[0019] 2. Add 11 kg of quicklime, 9 kg of gypsum, 12 kg of sucrose, 160 kg of cottonseed husks, and 110 kg of wheat bran to the processed Polygonum cuspidatum dregs, and mix well to obtain a culture medium for edible fungi.

[0020] The edible fungus culture medium obtained through the above treatment, wherein the mass fraction of resveratrol is 0.11%, the mass fraction of crude protein is 6.86%, the mass fraction of nitrogen-free extract is 32.18%, and the mass fraction of crude fiber is 35.72%. dry weight meter.

Abstract

The present invention discloses an edible fungi culture medium and a preparation method thereof. The preparation method comprises: (1) carrying out a pretreatment on giant knotweed rhizome drug residue, wherein the pretreatment comprises adding water to giant knotweed rhizome drug residue and carrying out enzymolysis; and (2) preparing an edible fungi culture medium, wherein the treated giant knotweed rhizome drug residue is added with quick lime, gypsum, sucrose, cottonseed hulls and wheat bran, and uniform stirring is performed. According to the edible fungi culture medium, a resveratrol mass fraction is more than or equal to 0.1%. a crude protein mass fraction is more than or equal to 6%, a nitrogen-free extract mass fraction is more than ore equal to 30%, and a crude fiber mass fraction is more than or equal to 30%. According to the present invention, a complex enzyme preparation is adopted to carry out fermentation and enzymolysis to improve components of the giant knotweed rhizome drug residue, such that the components are applicable for cultures of pleurotus eryngii, cap fungus, coprinus comatus and other edible fungi.

Description

technical field [0001] The invention relates to a method for preparing an edible fungus culture medium, in particular to a method for producing edible fungus culture medium with Polygonum cuspidatum dregs as the main raw material. Background technique [0002] Polygonum cuspidatum described in the present invention refers to the dry rhizome of Polygonum cuspidatum, which is a commonly used Chinese herbal medicine, distributed in Sichuan, Guizhou, Chongqing, Hubei, Hunan and other places, and has a sweet taste and flat nature. Polygonum cuspidatum contains multiple compounds such as resveratrol, polydatin, emodin, and nutrients such as cellulose, lignin, and protein. [0003] In my country, more than 100,000 tons of Polygonum cuspidatum is consumed every year for plant extraction and production of Chinese patent medicines, resulting in a large amount of Polygonum cuspidatum dregs. Polygonum cuspidatum dregs generally have high water content and certain nutrients, and are eas...
