Organic-selenium-rich edible mushroom production method

Abstract

An organic-selenium-rich edible mushroom production method is characterized in that firstly, wheat is subjected to slight germination (the technical term is sprout reveal) in a selenium-rich environment and turned into organic-selenium-rich malt; then, the organic-selenium-rich malt is dried and processed into flour, and meanwhile selenium-rich bran is obtained; then, the obtained selenium-rich bran serves as a raw material for producing selenium-rich edible mushrooms; the selenium-rich bran (or the selenium-rich malt) replaces common bran (or wheat) commonly used in an edible mushroom culture medium formula, a small amount of inorganic selenium in the selenium-rich bran is converted into organic selenium through the selenium enriching capability of edible mushrooms, and thus organic-selenium-rich edible mushrooms are obtained. By means of the organic-selenium-rich edible mushroom production method, the selenium-rich edible mushrooms can be produced, and meanwhile selenium-rich flour can be produced; as part of starch can be decomposed in the germination process of wheat, certain active enzymes can be generated, certain vitamins can be synthesized, and the nutrient ingredients of produced selenium-rich flour are optimized to a certain degree.

Description

technical field [0001] The invention relates to the field of biotechnology, and relates to a biotechnological method to enrich edible fungi with selenium to increase the content of organic selenium in fruiting bodies of the edible fungi, thereby meeting people's daily selenium supplement requirements. Background technique [0002] Edible fungi refer to mushrooms (large fungi) with large fruiting bodies that can be eaten, commonly known as mushrooms. There are more than 350 kinds of edible fungi known in China, most of which belong to Basidiomycotina. , Ganoderma lucidum, Cordyceps, Truffle, Lark and Boletus etc. Edible fungi are rich in protein and amino acids, and their content is several to dozens of times that of ordinary vegetables and fruits. The protein contained in 1 kg of dried mushrooms is equivalent to that of 2 kg of lean meat, 3 kg of eggs or 12 kg of milk. According to statistics from the China Edible Fungi Association, the annual output of edible fungi in my...

Problems solved by technology

Although the edible fungi cultivated by this method can meet the requirements of selenium-enriched edible fungi, some inorganic selenium that is harmful to the human body still exists in the edible fungus, and there is a risk of causing harm to the human body.

Moreover, when too much inorganic selenium is added to the edible fungi culture material, the growth of the edible fungi will be inhibited, resulting in a reduction in the output of the edible fungi.
