从大豆豆渣中提取大豆异黄酮的初步研究

The Prime Research on Extraction of Soybean Is oflavones from Soybean Residue

本实验以乙醇作为溶剂 ,以豆渣为原料 ,在不同提取条件和不同的豆渣预处理时 ,对豆渣中异黄酮的提取效果进行了研究。实验结果表明 ,豆渣经 90℃干燥后粉碎成 6 0目左右的颗料 ,在 80 - 10 0 %的乙醇溶液中 ,当温度为 6 0 - 70℃温度时 ,回流 6h ,提取效果比较好。

The article reports the research on the extraction of soybean isoflavones from soybean residue by alcohol.The good extraction parameter is as follow:after having been dried at 90℃ temperature,the soybean residue was ground to 0.6nm granular matter.Then at 60-70℃,it was refluxed in 80-100% alcohol for 6 hours.
