Production method of selenium-enriched black fungus

Abstract

The invention relates to a production method of selenium-enriched black fungus, comprising the following steps of: adding selenium salt in a strain medium of liquid seed production during preparation of liquid strain based on known strain medium prescription and cultivation management of liquid seed production of various black funguses; spraying the selenium salt dissolved in the strain medium into the sacked material where the black fungus grows along with the black fungus seed, exerting a decisive impact on the concentration of the selenium salt in the sacked material; controlling selenium content of the sacked material where the black fungus grows by controlling the concentration of the selenium salt of liquid strain medium. The method ensures that the selenium content of black fungus in unit weight is stable in the required scale while ensuring that each batch of black fungus taking the sacked material as nutrient contains selenium.

Description

technical field [0001] The invention relates to a production method of selenium-enriched black fungus. 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 selenium content cann...
