摘要
主要探讨豆粕中大豆异黄酮的最优醇提工艺。采用正交实验考察乙醇浓度、乙醇用量、提取温度、提取时间四因素对豆粕中大豆异黄酮的影响;采用高效液相色谱法测定染料木素、大豆苷元含量。结果最佳工艺条件为:原料用14倍体积的70%乙醇在70℃提取1h。
The best extractions technology of soybean isoflavones from soybean residue with alcohol, was discussed in the article. The effect of concentrate and amount of alcohol, temperature, times of extraction on the yield of soybean isoflavones were discussed. At the same time, the content of Genistein and Daidzein was determined by HPLC. The optimal processing is 14 times, volume 70% alcohol, lhour and 70℃.
