preparation example Construction

[0030] The preparation method of additive provided by the present invention:

[0031] The present invention selects corncobs with a selenium content of 0.2-30 micrograms / gram and corn stalks with a selenium content of 0.5-50 micrograms / gram. The selenium content in these materials is higher than that in my country's common diets, such as the selenium content in ordinary corncobs is 0.05- 0.20 μg / g, while the selenium-enriched corn cobs used in this technology have a selenium content of 0.2 μg / g or more, and the organic selenium contained in the selenium-substituted amino acids can be used as a high-quality selenium source absorbed by edible fungi.

[0032] The above-mentioned raw materials are further processed by nanotechnology, and the average particle size is 0.5-10.0 microns by using QYF-600 fluidized bed airflow pulverizer (power 188 kilowatts) of Miyou Group, so that the average particle size is 0.5-10.0 microns, and at the same time, more than 30% up to nanoscale particl...

Embodiment 1

[0040] 1. Test method

[0041] The production process includes: in the same culture environment in the edible fungi factory, use the edible fungus medium additive rich in nano-organic selenium prepared above, the selenium content is 0.2 micrograms / gram, according to the selenium-rich medium additive: base material=1:10 Ratio, set a blank control, with the same management measures, after 2 months of cultivation, detection.

[0042] 2. Test results

[0043] 1. Selenium content

[0044] The measurement results showed that the selenium content of the edible fungus in the selenium-enrichment test did not increase significantly.

[0045] 2. Output

[0046] There was no significant difference in yield between the selenium-enriched test area and the control area.

Embodiment 2

[0048] 1. Test method

[0049] The production process includes: in the same culture environment in the edible fungi factory, use the edible fungus medium additive rich in nano-organic selenium prepared above, the selenium content is 2.0 micrograms per gram, according to the selenium-rich medium additive: base material=1:10 Ratio, set a blank control, with the same management measures, after 2 months of cultivation, detection.

[0050] 2. Test results

[0051] 1. Selenium content

[0052] The selenium content of selenium-rich edible fungi is about 5.0 times higher than that of ordinary edible fungi.

[0053] 2. Output

[0054] At the same time, the selenium-enriched feed increased the growth rate of edible fungi. The average increase was 10.3%.

Abstract

The invention relates to an edible fungi culture medium additive, preparation and an application thereof. The edible fungi culture medium additive is prepared by raw materials rich in organic selenium, wherein, selenium content is 2.0-10.0mcg/g, and the raw materials rich in organic selenium comprise a corncob containing 0.2-30.0mcg/g organic selenium and a maize straw containing 0.5-50mcg/g organic selenium. The invention further provides a method for preparing the edible fungi culture medium additive: pulverizing the raw materials rich in organic selenium to obtain powder. The edible fungi cultured by the edible fungi culture medium additive of the invention has the advantages of stable content of the organic selenium, improved yield of the edible fungi by over 10%, low residual quantity of inorganic selenium and better safety.

Description

technical field [0001] The invention relates to an edible fungus culture medium additive and its preparation and application, in particular to an edible fungus culture medium additive rich in organic selenium and its preparation and application. Background technique [0002] Edible fungi are large fungi that are eaten by humans. There are more than 350 kinds of edible fungi known in China, and the common ones are: shiitake mushrooms, mushrooms, fungus, white fungus, Hericium erinaceus and Flammulina velutipes. Edible fungus is not only delicious, but also rich in nutrition. It is often called healthy food by people. For example, shiitake mushrooms not only contain various essential amino acids, but also have the effect of lowering blood cholesterol and treating high blood pressure. In recent years, it has also been found that shiitake mushrooms, mushrooms, Flammulina velutipes and Hericium erinaceus contain substances that enhance the body's ability to fight cancer. [000...
