摘要：本文主要研究了乙醇-水体系提取大豆异黄酮的工艺条件，经单因子实验与L9（34）正交实验，最终得到了该体系的最佳提取条件。如以总异黄酮作为提取目的，最佳条件为：80%的乙醇浓度，不小于18:1的物料比（溶剂:原料），时间1h，温度不超过50℃；如以genistin作为目的产物，则温度宜升高至70℃。
The research was mainly engaged in the extraction technology of isoflavones from soybean.The optimum extracting conditions were obtained after the study of the effects of ethanol concentration,solvent volume,extracting temperature and time.On the purpose to get the yield of total isoflavones as high as possible,the conditions would include 80% ethanol,at least 18:1 solvent volume to soybean weight,less than 50℃ temperature and not more than an nour time.If genistin was the only wanted product,then the temperature could be increased to 70℃.
