Embodiment 1

[0013] Corncobs and cottonseed hulls were not soaked, and were directly sterilized in a sterilizer to detect the contamination rate.

Embodiment 2

[0015] The corncobs are not soaked, and the cottonseed hulls are treated as follows: build a large water tank with bricks, put the cottonseed hulls crushed to the size of corn kernels into the pool, add clean water until the material surface is submerged, and make it fully absorb water. After soaking for 2-3 hours, drain the excess water, spread it on the ground to dry the excess water, and make the water content reach 60-65%. Cottonseed husks were fished out and mixed with corncobs, and then sterilized in a sterilizer to detect the contamination rate.

Embodiment 3

[0017] Cottonseed husks are not soaked, and corncobs are treated as follows: build a large water tank with bricks, put the corncobs crushed to the size of corn kernels into the tank, add water to submerge the material surface, and make it fully absorb water. After soaking for 2-3 hours, drain the excess water, spread it on the ground to dry the excess water, and make the water content reach 60-65%. After the corncobs were taken out and mixed with cottonseed hulls, the contamination rate was detected after being sterilized in a sterilizing cabinet.

Abstract

The invention relates to the field of edible fungus cultivation, in particular to a method for sterilizing edible fungi. In the following technical scheme, the method includes the steps that with corncobs and / or cotton seed hulls being raw materials, before usage, the corncobs and / or cotton seed shells are firstly smashed, soaked in water for 2-3 hours and then aired until the water content reaches 60-65%. Preferably, the method includes the step that the corncobs and / or cotton seed hulls are smashed to have the size of corn kernels. Compared with the prior art, the corncobs and the cotton seed hulls are pretreated, in this way, the effect of sterilization can be effectively improved, the number of bacteria in sterilized culture materials is decreased greatly, and mycete is killed completely; soaking time is shortened effectively, and it is prevented that since soaking time is too long, microorganisms are increased, and rancidity of the raw materials is generated.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a method for sterilizing edible fungi. Background technique [0002] Microorganisms are widely distributed in nature. The raw materials, water, equipment, and air involved in the production of edible fungi are attached to a large number of microorganisms and pests such as fungi, bacteria, actinomycetes, and viruses. They interact with edible fungi all the time. Competing for nutrients and invading edible fungi. These miscellaneous bacteria and pests and diseases cause great harm and losses to the production of edible fungi. [0003] All the nutrients needed for the growth and development of edible fungi come from compost, and most wood-rot fungi can be cultivated using sawdust, corncobs, cottonseed hulls, etc. as main materials, with guaranteed yield and low cost. Corncobs and cottonseed hulls commonly used in the production of edible fungi have the characteristics of p...
