Problems solved by technology

The content of selenium in the existing Ganoderma lucidum mycelium is generally only 3ppm, and basically exists in the form of inorganic state in the Ganoderma lucidum mycelium, the content is not high, and it is not conducive to human body absorption, and if the inorganic state selenium is absorbed too much Toxicity to the human body

Embodiment 1

[0031] Other steps are unchanged, as mentioned above, only the composition of the selenium salt medium in above-mentioned steps 5) is:

[0032] 2% corn flour, 1% soybean flour, 1% glucose, 0.1% potassium dihydrogen phosphate, 0.05% sodium selenite, 0.05% magnesium sulfate, 150ppm vitamin B, and the balance is deionized water. The content of selenium element in the selenium-enriched ganoderma lucidum mycelium product is 75ppm.

Embodiment 2

[0034] Other steps are as embodiment 1, just change the composition of the selenium salt culture medium in above-mentioned step 5) into: corn flour 5%, soybean flour 2%, glucose 3%, potassium dihydrogen phosphate 0.5%, sodium selenite 0.1 %, magnesium sulfate 0.1%, vitamin B1100ppm, and the balance is deionized water. The content of selenium element in the selenium-enriched ganoderma lucidum mycelium product is 89ppm.

Embodiment 3

[0036] Other steps are as embodiment 1, just change the composition of the selenium salt culture medium in above-mentioned step 5) into: corn flour 3.5%, soybean flour 1.5%, glucose 2%, potassium dihydrogen phosphate 0.3%, sodium selenite 0.07% %, magnesium sulfate 0.07%, vitamin B175ppm, and the balance is deionized water. The content of selenium element in the selenium-enriched ganoderma lucidum mycelium product is 81ppm.

[0037] The method for measuring the content of selenium in the above examples is a colorimetric spectrophotometer method, and the determination is carried out according to the national standard GB / T5009.93-2010.

Abstract

The invention discloses a production method for selenium-enriched ganoderma mycelium. The method comprises steps of: selecting strains, performing procedures of shaker, first-stage enlargement, second-stage enlargement and a selenium salt culture fermentation process at 25-26 DEG C, and finally performing pressure filtration and drying and crushing. The invention has the beneficial effects: ganoderma is enabled to accumulate selenium elements in a submerged liquid culture by designing a culture medium formula and optimizing and improving a production process, so that an inorganic form of selenium is transformed into organic selenium, so as to form a component of a ganoderma mycelium structure; therefore, selenium content of produced selenium enriched ganoderma mycelium is as high as 75-90 ppm; furthermore, organic selenium is more conducive to human body absorption; the selenium enriched ganoderma mycelium not only has wide pharmacological effects that the ganoderma has, but also has the pharmacological effects of the selenium element, including anticancer and anti-aging function, increasing of immunity-, improving of reproductive function and adjusting of absorption and utilization of vitamins, thereby providing a way for developing the efficient medicinal value of the ganoderma. The production process is easy and controllable, and mass production can be implemented.

Description

technical field [0001] The invention belongs to the technical field of edible and medicinal fungus production technology, and in particular relates to a production method of selenium-enriched ganoderma lucidum mycelium. Background technique [0002] Selenium is one of the essential trace elements for the human body, and is an indispensable component of glutathione peroxidase, which has a strong ability to protect the body's biomembrane from lipid peroxides. A large number of animal experiments have confirmed that selenium has good pharmacological effects such as anti-cancer, anti-aging, enhancing immunity, enhancing reproductive function, and regulating the absorption and utilization of vitamins. Ganoderma lucidum has a wide range of pharmacological effects, such as anti-tumor effect, immune regulation effect, sedative effect, cardiac strengthening and anti-myocardial ischemia effect, blood lipid regulation effect, anti-asthma effect, liver protection effect, anti-hypoxia an...
