Abstract:Soybean and mung bean as raw material，Sodium selenite solution for selenium source，The selenium-rich bean sprouts were cultivated by soaking and sprouting of soybean and mung bean. The optimum condition of the bean sprout growth and the amount of selenium accumulation were studied using single factor and orthogonal experiments to optimize the optimal parameters which the selenium-enriched bean sprouts grow.soybean and mung bean accumulate have different concentrations of selenium in the germination process，the mung bean sprout of selenium-rich ability is stronger than soybean sprouts. but，with selenium concentration and incubation time increases，selenium content in the bean sprouts showed increasing trend，However，with the increase of selenium concentration，the growth of bean sprouts was inhibited to some extent. The optimal production process of selenium-enriched soybean sprouts：selenium concentration was 6 μg/mL，the cultivation time was 5 d，selenium content was 8.82 μg/g.The optimal production process of selenium-enriched mung bean sprouts：selenium concentration was 16 μg/mL，the cultivation time was 4 d，selenium content was 42.23 μg/g.The experimental results showed：the enrichment capacity and growth characteristics of the mung bean sprouts were better and more suitable for the development of selenium-rich vegetables.
