Production method of selenium-rich mushroom

Abstract

On the basis of currently known spawn medium formulas and culturing management of various mushroom liquid prepared seeds, during the preparation of liquid spawn, selenite is additionally added in a spawn medium of liquid prepared seeds, the selenite which is dissolved in the spawn medium is sprayed in a bagged material for growing mushrooms along with a mushroom seed during grafting, which plays a decisive role in the density of the selenite in the bagged material, and thereby the selenium content of the bagged material for growing mushrooms is controlled by controlling the density of the selenite of the medium of liquid spawn, and each batch of mushrooms taking the bagged material as nutrients is ensured to contain rich selenium, and meanwhile, the selenium content of mushrooms in unit weight is stable within the required range.

Description

Technical field

[0001] The invention relates to a production method of selenium-enriched mushrooms. Background technique

[0002] Selenium is an essential trace element for the human body. A lack of selenium can cause a variety of diseases in the human body. Most areas of our country lack selenium, and selenium supplementation is an urgent need. Because the human body's safe daily intake of inorganic selenium is relatively narrow, and the human body is more tolerant of organic selenium, converting inorganic selenium into organic selenium and then absorbed by the human body is the best way for the human body to safely supplement selenium. Shiitake mushrooms have a strong ability to transform inorganic selenium into organic selenium during the growth process. The development of selenium-enriched mushrooms is in the contemporary era and will benefit the future. However, what is regrettable is that there is currently no mass production of selenium-enriched mushrooms with stable sele...

Examples

Embodiment Construction

[0005] After 90Kg water and 9Kg potatoes are boiled until crisp, add 1.35Kg brown sugar, 0.9Kg glucose, 3.6Kg wheat bran, 0.18Kg peptone, 0.18Kg potassium dihydrogen phosphate, 0.09Kg magnesium sulfate, 0.9g vitamin VB1, and 27ml bubble enemy And 6 grams of sodium selenite, filtered to become a liquid culture medium. After disinfection and inoculation of the liquid strain, the preparation of the liquid strain is completed. It can be a bag after mixing, bagging and sterilization The selenium-enriched mushrooms with stable selenium content can be obtained by inoculating the culture medium, growing the bacteria, extracting ears and harvesting.
