Embodiment 1

[0012] Corncobs and cottonseed hulls were not pretreated by soaking, and were directly sterilized in a sterilizer to detect the contamination rate.

Embodiment 2

[0014] The corncobs are not pretreated by soaking, 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, and add clean water to submerge the surface of the material to 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

[0016] Cottonseed husks are not pretreated by soaking, 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 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%. 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, and in particular relates to a method for pretreating edible fungus raw materials. The method is realized through the following technical scheme: corncobs and / or cottonseed hulls are taken as raw materials, ground before being used, soaked in water for 2-3 hours, and aired until the water content reaches 60-65%. The preferable method is as follows: the corncobs and / or cottonseed hulls are ground into niblet sizes. Compared with the prior art, the corncobs and the cottonseed hulls are pretreated, so the sterilization effect can be effectively improved, the bacterial count of compost after the sterilization is greatly reduced, and mould is completely killed; and the soaking time is effectively shortened, and the microorganism reproduction and raw material rancidity due to long soaking time are avoided.

Description

technical field [0001] The invention relates to the field of edible fungus cultivation, in particular to a pretreatment method for raw materials of 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 ch...
