Abstract: The nutritional components were extracted from selenium-enriched Auricularia auricula,and the selenium content in the components was analyzed. Results showed that total selenium content in Auricularia auricula is 5.148 mg/kg. The selenium in protein accounts for 52.03% of total selenium,the selenium in polysaccharide accounting for 22.64%. The addition amount of selenium is positively proportional to mass fraction of coarse fiber in Auricularia auricula,but no effect on coarse ash.

Key words: Auricularia auricular, selenium enrichment, nutrition components
