Problems solved by technology

[0003] However, the current method of producing selenium-enriched black fungus is mostly to add inorganic selenium to the cultivation material, such as "Cultivation method of selenium-enriched black fungus" (application number 201010154424.5), "Cultivation of edible fungi such as selenium-enriched fungus produced with selenium mineral powder Method" (application number 200910067120.2) and "black fungus production method rich in organic selenium" (application number 201110099832.X), etc., this method of adding inorganic selenium to the cultivation material, black fungus absorbs less inorganic selenium, and is easy to cause environmental pollution. Selenium pollution; and the invention patent application for the method of cultivating selenium-rich fungus by using selenium-rich crop stalks (application number 201210290103.7), the technical solution is realized by adding selenium-rich wheat or corn stalks to the cultivation material, although the solution is feasible , but it is difficult to produce selenium-enriched wheat or corn stalks (with a selenium content of 1-80 mg / kg) through the existing technology

Abstract

The invention relates to a selenium-rich black fungus culture material and a preparation method thereof. The culture material is prepared from the following raw materials in percentage by weight: 65-73% of corn cob, 18-24% of selenium-rich lucerne meal, 5-11% of wheat straw, 0.8-1.2% of calcium superphosphate, 0.2-0.8% of gypsum and 0.3-0.9% of lime. The selenium-rich black fungus culture material has the advantages of reasonable raw material proportioning, balanced nutrients and high utilization ratio of selenium; and the C / N ratio satisfies the culture demands for black fungus. The selenium content of the black fungus produced by the culture material according to the conventional bag-type culture technique reaches 0.15-3.0 mg / kg which is 5-100 times of the common black fungus; the black fungus has rich nutrients, and is an excellent selenium-supplementing green health-care product; the sales price is 10% higher than that of the common black fungus; and the culture material has wide development prospects.

Description

Technical field: [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to a selenium-enriched black fungus cultivation material and a preparation method thereof. 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 narrow, and the human body’s tolerance to organic selenium is relatively large, so supplementing organic selenium is the best way to safely supplement selenium for the human body. Black fungus is soft in texture, delicious in taste, rich in nutrition, and can be either vegetarian or meat. It not only adds style to Chinese dishes, but also nourishes blood and keeps the face, makes the skin rosy and radiant, and can prevent a...
