摘要: 以富硒黑木耳为原料,对其相关营养成分进行提取和分离。结果显示,样品总硒的质量分数为5.148mg/kg,蛋白硒占总硒的质量分数为52.03%,多糖硒占总硒的质量分数为22.64%。施硒量与富硒黑木耳中粗纤维质量分数成反比;而施硒量对富硒黑木耳中粗灰分质量分数影响不大。

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
