Embodiment 1

[0013] Put the mixture of cottonseed husks, wheat bran and broccoli boiled liquid into a container and mix well, adjust the temperature to 35°C, add glucoamylase and mix well, leave it for 1.5 hours to obtain the edible fungus culture medium.

[0014] In the mixture of cottonseed hulls and wheat bran, the mass fraction of cottonseed hulls is 65%, and the rest is wheat bran.

[0015] The ratio of the mixture of cottonseed hulls, wheat bran and broccoli boiling liquid is 1:1.3 by weight.

[0016] The amount of glucoamylase added is 85 units / gram of raw material.

Embodiment 2

[0018] Put the mixture of cottonseed hulls, wheat bran and broccoli boiled liquid into a container and mix well, adjust the temperature to 60°C, add glucoamylase and mix well, leave it for 3 hours to obtain the edible fungus culture medium.

[0019] In the mixture of cottonseed hulls and wheat bran, the mass fraction of cottonseed hulls is 87%, and the rest is wheat bran.

[0020] The ratio of the mixture of cottonseed hulls, wheat bran and broccoli boiling liquid is 1:1.5 by weight.

[0021] The amount of added glucoamylase is 168 units / gram of raw material.

Embodiment 3

[0023] Put the mixture of cottonseed hulls, wheat bran and broccoli boiled liquid into a container and mix well, adjust the temperature to 51°C, add glucoamylase and mix well, leave it for 4.5 hours to obtain the edible fungus culture medium.

[0024] In the mixture of cottonseed hulls and wheat bran, the mass fraction of cottonseed hulls is 75%, and the rest is wheat bran.

[0025] The ratio of the mixture of cottonseed hulls, wheat bran and broccoli boiling liquid is 1:1.7 by weight.

Abstract

The invention discloses preparation method for a culture medium of an edible fungus. The method includes the following steps: placing a mixture of cottonseed hull and wheat bran, and a water-boiled liquid of broccoli in a container and then uniformly stirring, adding and uniformly stirring glucoamylase after the temperature is adjusted to 30 DEG C-65 DEG C, and then continuing to place for 1-5 h to obtain the culture medium. The culture medium of the edible fungus obtained by utilizing the preparation method can be used for cultivating various edible fungi such as pleurotus eryngii, pleurotusostreatus, and coprinus comatua, is high in biotransformation rate, effectively utilizes resources, and enables the burden of environmental pollution to be reduced. The preparation method also makes the water-boiled liquid of the broccoli turn into treasure, achieves harmless comprehensive utilization, enhances the added value of the broccoli, and has a broad application prospect.

Description

technical field [0001] The invention relates to a formula and a preparation method of a culture medium for edible fungi, in particular to a method for producing a culture medium for edible fungi by using broccoli boiled liquid, cottonseed hulls, wheat bran and glucoamylase as raw materials. Background technique [0002] Broccoli is an annual plant of the genus Brassicaceae and Brassica. Broccoli is a nutritious health-care vegetable, rich in nutrients, and has various health effects such as anti-cancer, anti-cancer, scavenging free radicals in the body, and anti-oxidation, and is deeply loved by consumers. [0003] Broccoli is widely used to process quick-frozen broccoli. The annual output of quick-frozen broccoli in China is more than 800,000 tons. In the production of quick-frozen broccoli, enzyme-killing treatment is required to prolong the shelf life of quick-frozen broccoli. In the enzyme killing process, the broccoli should be boiled in boiling water at 95°C-100°C for...
