Prepn process of selenium-rich edible fungus with activated selenium ore as selenium source

Abstract

The preparation process of selenium-rich edible fungus with activated selenium ore as selenium source belongs to the field of biological selenium resource converting technology. Natural selenium ore as the selenium source is crushed, activated and water extracted; the selenium containing water solution is used in compounding culture medium; and edible fungus is cultured to realize selenium conversion and enrichment, with the selenium-enriching cultured mycelium containing organic selenium in 50-600 mg / kg. The present invention realizes the conversion and enrichment of organic selenium while producing edible fungus with rich active polysaccharide content.

Description

technical field

[0001] A method for preparing a selenium-enriched edible fungus product using activated selenium ore as a selenium source. The present invention uses activated selenium ore as a selenium source and uses edible fungi to transform and enrich organic selenium. The preparation method of a biological selenium-enriched product belongs to Selenium resource biotransformation technology field. Background technique

[0002] Selenium is an indispensable trace element for human life. It has dual functions of preventing and treating cancer. Many acute and chronic diseases such as anemia, coronary heart disease, Kashin-Beck disease, Keshan disease and diabetes are also closely related to selenium deficiency. At present, there are more than 40 countries and regions lacking selenium in the world, and there are 715 counties and cities in my country, and about 100 million people are deficient in selenium.
