结论 以黄豆渣为原料生产异黄酮成本低，变废为宝，具有实际意义。

CONCLUSION It is practical to extract and separate isoflavonoids from soy residue after the reprocessing of soy.

最近的证据表明了在去异黄酮化期间GA浓度的波动。

Recent evidence suggests fluctuations in GA concentration during de-etiolation.

但论述者没有作出陈述，即这些异黄酮是否是以一种被人体使用的方式被包含在大豆中。

What is not stated, however, is whether these isoflavones are contained in a form in soy that is usable by the human body.
