| 中文摘要: |
| 建立了一种针对大豆乳清水一级浮渣粉（SP）中大豆异黄酮的提取、分离和纯化方法。结果表明：以60%乙醇为提取溶剂，在料液比1∶ 5、提取温度60~70 ℃下采用胶体磨提取2次，每次075 h，每100 g SP可提取干物质20 g，大豆异黄酮含量为2.08%。该20 g提取物加20 g Ca3(PO4)2、8 g Ca(HCO3)2和400 mL 95%乙醇沸腾回流1 h，过滤浓缩后可得3.05 g膏状物，大豆异黄酮含量为13.6%，除杂分离效果好。用大孔树脂ADS-21对膏状物吸附洗脱，浓缩得大豆异黄酮产品，含量为83.5%，为洗脱前膏状物的6.14倍。 |

| A method for the extraction, separation and purification of soy isoflavones from soy whey water first stage scum powder(SP) was established. The results showed that with 60% ethanol as extraction solvent, under the conditions of ratio of material to liquid 1∶ 5, milled by colloid mill at 60~70 ℃ for twice, 0.75 h each time, every 100 g of SP could get dry matter 20 g, and the soy isoflavones content was 2.08%. Adding 400 mL 95% ethanol, 20 g calcium phosphate and 8 g calcium bicarbonate to 20 g extract, the extract was refluxed for 1 h. After filtered and concentrated, 3.05 g paste was obtained with soy isoflavones content 13.6%, which showed good effect of impurity removal and separation. The paste was eluted by macroporous resin ADS-21, and soy isoflavones product was obtained with the content of soy isoflavones product 83.5%, which was 6.14 times of the content of sample uneluted. |
