Daily Intake of Isofavones Based on the Market Basket Method

摘要

Daily intake of isoflavones (daidzin, glycitin, genistin, daidzein, glycitein, and genistein) was determined quantitatively, based on the market basket method. Acid hydroltsis during extrac- tion of foods was chosen to convert phytoestrogenes into the respective aglycons, facilitating HPLC analysis and allowing quantitation of total isoflavones as aglycones including both original- Ly present glycosides and "free" aglycones.
