Example Embodiment

[0030] Example 1

[0031] A preparation method of fungus powder, including:

[0032] S1. The fungus is selected and pretreated to soften the gum layer of 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, perform secondary crushing and filtering, collect the filtered product, and return the filter residue to the crusher to continue crushing.

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

[0036] The present invention adopts a secondary crushing method to prepare fungus powder, where the first crushing is dynamic pressure crushing under specific conditions. The crushed product in this step is difficult to reach the level of fine powder, but the special treatment and crushing in this step of the present invention can be extremely ...

Example Embodiment

[0037] Example 2

[0038] Based on the preparation method of the fungus powder described in Example 1, the pretreatment in step S1 includes: first, washing the fungus with negative ion water. Afterwards, the washed fungus was immersed in a preparation solution environment of 30°C and pH 6.5 for 12 minutes. Finally, the fungus is dried until there are no water droplets on the surface before use. The preparation liquid is prepared by mixing vinegar and water.

[0039] Based on an embodiment of the present invention, the pretreatment in step S1 includes: first, washing the fungus with negative ion water. Afterwards, the cleaned fungus was immersed for 10 minutes in a mixing solution environment at 40°C and pH 6.3.

[0040] Based on an embodiment of the present invention, the pretreatment in step S1 includes: first, washing the fungus with negative ion water. Afterwards, the cleaned fungus was immersed for 15 minutes in a solution environment at 25°C and pH 6.8.

[0041] This method c...

Example Embodiment

[0042] Example 3

[0043] Based on the method for preparing the fungus powder described in Example 1, the method of crushing under dynamic pressure 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 with 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 4 atmospheres in the cabin for 6 minutes.

[0046] (3) On the basis of stopping the operation of the crushing mechanism, maintain 4 atmospheres in the cabin for 20 minutes. Then adjust the air pressure in the cabin 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 operate for 7 minutes. After maintaining the operation of the crushi...

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...
