Cultivation method of black fungus rich in selenium

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

technical field

[0001] The invention relates to a method for cultivating black fungus rich in trace element selenium. Background technique

[0002] Selenium is an essential trace element for the human body. Selenium deficiency can cause various diseases in the human body. Selenium deficiency in most areas of my country requires quantitative supplementation of selenium without delay. Because the range of human body’s daily safe intake of inorganic selenium is relatively narrow, and the human body’s tolerance to organic selenium is relatively large, converting inorganic selenium into organic selenium and then absorbing it for the human body is the best way for the human body to safely supplement selenium. Black fungus has a strong ability to transform inorganic selenium into organic selenium during the growth process. The development of selenium-enriched black fungus will benefit the future. However, it is regrettable that the selenium-enriched black fungus with stable seleni...

Examples

Embodiment Construction

[0005] After dissolving 2g of food-grade sodium selenite with a purity of 99% in 600Kg of water, mix it with 780Kg of sawdust, 200Kg of bran, 10Kg of gypsum powder, and 10Kg of white sugar, and use it as a medium for cultivating selenium-enriched black fungus for bagging , sterilizing, inoculating, cultivating bacteria, removing ears and harvesting, the selenium-enriched black fungus with stable selenium content can be obtained.
