浸泡条件对发芽大豆中硒富集量的影响

摘要

The effect of Na2SeO3 concentration, soaking time and temperature on germination rate and se -accumulation of soybean were investigated by response surface methodology based on central composite design （CCD）. The result indicated Na2SeO3 concentration of 50 mg/L, soaking for 4h at 29.6 ℃ was the best. Under these conditions, the maximal germination rate and Se content were 92.22% and 11.87 μg/g dry weights, respectively.%探讨了Na2SeO3浓度、浸泡时间和浸泡温度对大豆发芽率和硒富集量的影响。在单因素试验的基础上，通过响应面试验确定了富硒大豆芽最适浸泡条件为：Na2SeO3浓度50mg／L、浸泡时间4h和浸泡温度29．6℃。在此条件下，富硒大豆发芽率达到92．22％、总硒量11．87μg／g干重。
