Embodiment 1

[0031] A preparation method of fungus fine powder, comprising:

[0032] S1. Select the fungus and perform pretreatment to soften the gum layer of the fungus.

[0033] S2. Put the pretreated fungus in a crusher and crush it under dynamic pressure.

[0034] S3. After drying the crushed product obtained in S2, carry out secondary crushing and filtration, collect the filtered product, and return the filter residue to the crusher for further crushing.

[0035] S4. Repeat step S3 until the filter residue is lower than the preset value, and collect multiple filtration products of the same batch of fungus, and obtain the fungus fine powder after drying.

[0036] The present invention adopts the method of secondary crushing to prepare fungus powder, wherein the first crushing is dynamic pressure crushing under specific conditions, and the crushed product in this step is difficult to reach the degree of fine powder, but through the special treatment and crushing of this step of the pre...

Embodiment 2

[0038] Based on the preparation method of fungus fine powder described in Example 1, the pretreatment in step S1 includes: first, washing fungus with negative ion water. Afterwards, soak the washed fungus in the preparation solution at 30°C and pH 6.5 for 12 minutes. Finally, dry the fungus until there are no drops of water on the surface for later use. The compounding solution is obtained by compounding vinegar and water.

[0039] Based on one embodiment of the present invention, the pretreatment in step S1 includes: first, washing the fungus with negative ion water. Afterwards, soak the washed fungus in the preparation solution at 40°C and pH 6.3 for 10 minutes.

[0040] Based on one embodiment of the present invention, the pretreatment in step S1 includes: first, washing the fungus with negative ion water. Afterwards, soak the washed fungus in the preparation solution at 25°C and pH 6.8 for 15 minutes.

[0041] This method can effectively soften the gelatinous layer of ...

Embodiment 3

[0043] Based on the preparation method of fungus fine powder described in Example 1, the method for crushing under dynamic pressure described in step S2 includes:

[0044](1) Start the crushing mechanism in the crusher under normal pressure, and crush the fungus in the crusher cabin for 7 minutes.

[0045] (2) On the basis of maintaining the operation of the crushing mechanism, pressurize the cabin containing the fungus in the crusher, and increase the pressure in the cabin to 4 atmospheres within 30 minutes. After that, maintain the operation of the crushing mechanism and the pressure of 4 atmospheres in the cabin for 6 minutes.

[0046] (3) On the basis of stopping the operation of the crushing mechanism, maintain the pressure of 4 atmospheres in the cabin for 20 minutes. Then adjust the air pressure in the chamber to a vacuum of -0.06MPa.

[0047] (4) On the basis of keeping the vacuum degree in the cabin at -0.06MPa, start the crushing mechanism to run for 7 minutes. Af...

Abstract

The invention provides a method of preparing fine auricularia auricula powder in order to overcome the deficiencies of the prior art. The method includes the steps that S1, auricularia auricula is selected and pretreated to soften the gelatinous layer of the auricularia auricula; S2, pretreated auricularia auricula is placed in a crusher and crushed under dynamic pressure; S3 the crushed product obtained in S2 is dried and then subjected to secondary crushing and filtration, the filtered product is collected, and the filter residue is returned to the crusher to continue to be crushed; S4, stepS3 is repeated until the filter residue is lower than a preset value, and the plurality of filtered products of the same batch of the auricularia auricula are collected and dried to obtain the fine auricularia auricula powder. The method has low requirements for equipment, can achieve a good wall breaking and crushing effect, and can obtain auricularia auricula powder with an absorption rate of active components of 90% or above. The activity of the active components of the auricularia auricula powder is high, and compared with that obtained through a high temperature processing technology, the auricularia auricula powder obtained by the method can effectively play the original effect of the auricularia auricula.

Description

technical field [0001] The invention belongs to the technical field of edible fungus processing, and in particular relates to a preparation method of fungus fine powder. Background technique [0002] Black fungus is one of the earliest artificially cultivated commercial fungi among edible fungus varieties in my country. Mainly distributed in Heilongjiang, Jilin, Fujian, Hubei, Guangdong, Guangxi, Shandong, Jiangsu, Sichuan, Guizhou, Yunnan and other places. According to statistics from the China Edible Fungi Association, the total output of black fungus in China in 2011 has exceeded 2.7 million tons, and the output has increased very rapidly. At present, my country's black fungus production and consumption rank first in the world. [0003] Black fungus [Auricularia auricular (L.ex Hook.) Underw] also known as black cabbage, light fungus, cloud ear, mycological classification belongs to Basidiomycetes, Auricularia, Agaricaceae. It is a precious colloidal fungus used both f...
