CN101803532A - Cultivation method of black fungus rich in selenium - Google Patents

Abstract

The invention relates to a cultivation method of black fungus rich in selenium, which only additionally adds an aqueous selenium salt solution during the material stirring of a culture medium on the basis of well-known various culture medium bagged material formulas and the cultivation management of black fungus, and the total amount of selenium salt dissolved in water plays a crucial role in the concentration of the selenium salt contained in culture medium bagged materials. The invention controls the selenium content of the black fungus taking the culture medium as a nutrient by controlling the concentration of the selenium salt contained in the culture medium bagged materials, ensures the black fungus produced every batch to be rich in the selenium and also enables the selenium content of the black fungus with unit weight to be stabilized within a needed range.

Description

The cultivation method of black fungus rich in selenium

Technical field

The present invention relates to a kind of cultivation method that is rich in the woodear of trace elements of selenium.

Background technology

Selenium is the necessary a kind of trace element of human body, and scarce selenium can cause the multiple disease of human body, and China overwhelming majority area lacks selenium, quantitatively mends selenium, and is very urgent.The scope of taking in inorganic selenium because of human body safety every day is narrower, and human body is bigger to the tolerance degree of organic selenium, is absorption of human body again after changing inorganic selenium into organic selenium, is the best approach of human body safe selenium-complement.Woodear has very strong transformation inorganic selenium in process of growth be the ability of organic selenium, and contributes to contemporary times and brings benefits for future centuries for the exploitation black fungus rich in selenium.Yet, regrettably: fail to produce in enormous quantities the stable black fungus rich in selenium of selenium content in the society at present.

The invention has the beneficial effects as follows: can produce the stable black fungus rich in selenium of selenium content in enormous quantities, be convenient to people and quantitatively mend selenium.

Summary of the invention

The present packed medium cultivation of known woodear process is: the production of hybrid seeds, spice, pack, sterilization, inoculation, bacteria, go out ear, several links such as gather.The invention provides a kind of cultivation method of black fungus rich in selenium, the technical scheme that realizes is on known various blackfungus culture medium sacked materials are at present filled a prescription the basis of sharp cultivation management, when the medium spice, add the selenium saline solution in addition, selenium salt total amount soluble in water has played conclusive effect to the concentration of the selenium salt of culture medium bag charging, the concentration of the selenium salt by control culture medium bag charging, thereby controlled with this medium is the selenium content of the woodear of nutrient, guarantee that every series-produced woodear enriches when containing selenium, the woodear selenium content of Unit Weight is stabilized in the required scope, is convenient to people and quantitatively mends selenium.

Specific embodiment

After in 600Kg water, dissolving in 2g purity and be 99% food-grade sodium selenite, with the 780Kg wood chip, the 200Kg wheat bran, the 10Kg land plaster, 10Kg white sugar mixes to be mixed thoroughly, medium as the cultivation of selenium-rich woodear packs, sterilization, inoculation, bacteria, goes out ear and gather, and can obtain the stable rich selenium China ink auricularia auriculajudae of selenium content.

Claims (1)

1. the cultivation method of a black fungus rich in selenium, it is characterized in that: on the basis of at present known various blackfungus culture medium sacked material prescriptions and cultivation management, when the medium spice, add the selenium saline solution in addition, the concentration of the selenium salt by control culture medium bag charging, thus control is the selenium content of the woodear of nutrient with this medium.
