Method for producing enoki mushrooms rich in selenium and zinc

Abstract

The invention discloses a method for producing enoki mushrooms rich in selenium and zinc and belongs to the field of edible fungi cultivation. The method comprises stock preparation, original strain preparation and enoki mushroom cultivation. Sodium selenite and zinc sulfate are added in a stock preparation culture medium and an original strain preparation culture medium and enoki mushroom culture compost. The stock preparation culture medium is composed of, by weight, 200g of potatoes, 25g of glucose, 30g of agar, 3g of peptone, 0.5g to 1g of monopotassium phosphate, 0.5g to 1.5g of magnesium sulfate, 11mg to 13mg of sodium selenite, 0.2g to 0.4g of heptahydrate and 1000g of water. The enoki mushrooms are high in selenium and zinc absorption in the growth process, and the yield is high.

Description

technical field [0001] The invention relates to a production method of Flammulina velutipes, in particular to a production method of Flammulina velutipes rich in selenium and zinc, and belongs to the field of edible fungus cultivation. Background technique [0002] Selenium and zinc are essential trace elements for the human body. Selenium deficiency will significantly reduce the body's immunity. Selenium-deficient areas are prone to endemic diseases such as Keshan disease, Kaschin-Beck disease, and cardiovascular and cerebrovascular diseases. Appropriate amount of selenium can significantly improve cancer, cataract, and malnutrition in children, and can avoid arteriosclerosis, hypertension, myocardial infarction, senile neurological insufficiency, memory and mental retardation, etc. the occurrence of disease. Selenium supplementation can eliminate free radicals in the body, reduce the viscosity of whole blood and plasma; supplementation of selenium is beneficial to promote...

Problems solved by technology

There are many kinds of selenium-enriched health food on the market, but its relatively expensive price limits the consumer groups, and it is difficult to be accepted by the general consumers. Flammulina velutipes is a kind of edible fungus that is widely accepted and loved by the public. It is rich in selenium. Zinc-rich Flammulina velutipes can not only supplement the trace elements of the human body, but also increase the added value of edible fungus cultivation. Therefore, the development of economical, convenient, and selenium-enriched Flammulina velutipes products suitable for direct consumption has broad prospects
