Abstract

The invention discloses an application method for a selenium-rich hericium erinaceus culture medium. The application method includes the steps of 1), taking and mixing a moderate amount of main materials and auxiliary materials to form a mixture; 2), adding appropriate acetic acid to the main and auxiliary material mixture to adjust the PH (potential of hydrogen) value to be 5.5, and putting the adjusted acid mixture into a plastic bag; 3), enclosing the acid mixture under the temperature ranging from 50DEG C to 80DEG C for 2.5 hours, and then performing inoculation of hericium strains after cooling; 4), after cultivation for 30-35 days under the temperature ranging from 23DEG C to 28DEG C, shifting the acid mixture into a fruiting chamber for moisturizing and fruiting and collecting selenium-rich hericium erinaceus after 15-20 days. With the method, medium bacteria grow vigorously, the hericium erinaceus is high in selenium element, nutritional value of the bacteria is comparatively higher, utilization rate of the bacterial strains on the culture medium is high, biological transformation efficiency is high, cost is saved, and economical effectiveness in cultivation of the hericium erinaceus is improved.

Description

The using method of the medium of a kind of rich selenium Hericium erinaceus

Technical field:

The present invention relates to the production field of Hericium erinaceus, particularly relate to a kind of using method of Hericium erinaceus medium.

Background technology:

Hericium erinaceus is the luxury dish of Chinese tradition, and meat is tender, taste is fragrant, tasty.One of four large famous dishes (hedgehog hydnum, bear's paw, sea cucumber, shark's fin).There is the title of " mountain delicacy hedgehog hydnum, seafood delights bird's nest "; The nutrient component of Hericium erinaceus is very high, and every hectogram, containing 26. 3 grams, protein, is two times of mushroom.It contains much 17 kinds of amino acid, wherein needed by human body account for 8 kinds.Fatty 4.2 grams of every hectogram hedgehog hydnum, is genuine high protein, low-fat food, is also rich in various vitamin and mineral salt in addition.Hericium erinaceus improves a poor appetite, and strengthens barrier of gastric mucosa function, improves lymphocyte transformation rate, promotes the effects such as leucocyte.

What current Hericium erinaceus medium on the market adopted is wood chip 26%, wheat skin 20%, gypsum or calcium carbonate 2%, sugar 1%, superphosphate 1% is primary raw material cultivation Hericium erinaceus, the carbon source nutritive element of weed tree sawdust is single, the growing environment restriction element of the Hericium erinaceus cultivated is more, output is relatively low, and select wheat skin to be the nitrogenous source that Hericium erinaceus grows, the more difficult Root decomposition by Hericium erinaceus of its nitrogen element absorbs, be unfavorable for the expansion of Hericium erinaceus bacterial strain and cap, the nutritive value and the composition that cause the Hericium erinaceus grown out are less, the content of trace element is lower, be unfavorable for the eutrophic absorption of people.

In order to solve the problem, it is lower that the present invention proposes a kind of cost, is rich in the using method of the Hericium erinaceus medium of selenium element.

Summary of the invention:

The object of the invention is to provide the using method of the medium of a kind of rich selenium Hericium erinaceus.

Scientific circles' research finds, the height of blood selenium level is closely bound up with the generation of cancer.A large amount of survey data explanations, a regional food and the height of Selenium in Soils content have direct relation with the incidence of disease of cancer, such as: the Se content in the food in this area and soil is high, the M & M of cancer is just low, otherwise, the cancer morbidity in this area and lethality are just high, the generation close relation of statement of facts selenium and cancer.Scientific circles also recognize that selenium is " anticancer king " in body trace element simultaneously.Selenium is the active component forming glutathione peroxidase, and it can prevent beta Cell of islet Oxidative demage, makes its function normal, promotes sugared part metabolism, reduces blood sugar and glucose in urine, improve the symptom of diabetic.

For achieving the above object, the present invention proposes the using method of the medium of a kind of rich selenium Hericium erinaceus, comprises the steps:

(1) get appropriate major ingredient and auxiliary material mixes, form a mixture;

(2) in described major ingredient auxiliary material mixture, add proper amount of acetic acid regulates pH value to be 5.5, loads in plastic sack by the mixture after regulating;

(3) at said mixture being enclosed in 50-80 DEG C, sterilizing 2.5 hours, carries out the inoculation of hedgehog fungus bacterial after cooling;

(4) at the temperature of 23-28 DEG C after the cultivation of 30-35 days, shift-in mushroom producing room carries out moisturizing fruiting, gathers and can obtain rich selenium Hericium erinaceus after 15-20 days.

The medium of this rich selenium Hericium erinaceus is by weight being major ingredient: auxiliary material=5:1 configuration forms.

In the medium of this rich selenium Hericium erinaceus, major ingredient is become by cotton seed hulls, rice sprout, Fu Xi local soil type, and described adjunct ingredient has: broad-leaved wood chip, fermentation horsehit, fructose, urea, gypsum, sodium selenite, ammoniacal liquor, zinc sulphate, calcium dihydrogen phosphate.

The medium of this rich selenium Hericium erinaceus is prepared from by the batching of following parts by weight and auxiliary material:

Cultivating weight portion in major ingredient is: cotton seed hulls: rice sprout: rich selenium soil=6:3:1;

In medium auxiliary material, weight portion is: broad-leaved wood chip 30-35, fermentation horsehit 20-25, fructose 2-3, urea 2-4, gypsum 1-2, sodium selenite 400ppm, ammoniacal liquor l000ppm, zinc sulphate 500ppm, calcium dihydrogen phosphate l000ppm;

The medium of above-mentioned rich selenium Hericium erinaceus is by weight being major ingredient: auxiliary material=5:1 configuration forms;

Above-mentioned rich selenium soil is contain the earth that selenium element wt mark is the rich selenium element of 2%-5%.

The invention has the beneficial effects as follows, proportioning is simple, easy to use, while reduction conventional medium cost, effectively ensure that the selenium constituent content of Hericium erinaceus.And biologicak efficiency is high, method is simple, and cost is low, is easy to promote.

Embodiment:

Embodiment 1

Carry out the use of medium according to the method described above, step is as follows:

Medium major ingredient weight portion is: cotton seed hulls: wheat drum head: earth=60 kilogram: 30 kilograms: 10 kilograms.Medium auxiliary material weight portion is broad-leaved wood chip 35, and fermentation horsehit 20, fructose 3, urea 2, gypsum 1, sodium selenite 400ppm, ammoniacal liquor l000ppm, zinc sulphate 500ppm, calcium dihydrogen phosphate l000ppm, take 20 kilograms by above-mentioned weight portion.Get 100 kilograms of major ingredients, 20 kilograms of auxiliary materials mix.

Use the contrast of the Hericium erinaceus of cultivation of the present invention and traditional Hericium erinaceus as follows:

Embodiment	Finished product Hericium erinaceus selenium content (every 100 grams)	Cost
			Tradition Hericium erinaceus	0.2ug	Radix is 1
Rich selenium Hericium erinaceus	0.32ug	Comparatively radix reduces 5-15%

Proportioning of the present invention is simple, and easy to use, the medium of described Hericium erinaceus, substantially increases the rich Se content of Hericium erinaceus, and reduce the cost of cultivation.
