Research progress on selenium accumulation characteristics of higher edible fungi

Selenium is an important essential trace element in the human body.It has three biological functions of nutrition,detoxification and toxicity.The geographical distribution of selenium is extremely uneven and food is the most important source of direct selenium.Microorganisms play an important role in the geochemical cycle of selenium.As a good selenium-enriched carrier,higher edible fungi have broad prospects for the development of selenium-enriched products.The selenium detection,the selenium-enrichment effect of selenium-enriched edible fungi,the selenium form,and the mechanism of selenium absorption and metabolism were summarized,and the current difficulties and prospects of selenium-enriched edible fungus were analysed in order to achieve research and production in this area for reference.
