测定了13个大豆品种中染料木素及其β-葡萄糖苷形式染料木素的含量。以染料木素和染料木素含量较高（0.019 mg/g和0.420 mg/g）的大豆品种Var-1为研究材料，对3种碱性大豆浓缩蛋白（SPC）生产方法（酸法、醇法和热水浸出法）对染料木素和染料木素总重的影响进行了评价。与热水浸出法（0.671 mg/g）和酒精浸出法（0.070 mg/g）相比，酸浸法制备的染料木素+染料木素含量最高（0.742 mg/g）。酸浸、热水浸和醇浸的染料木素+染料木素总损失率分别为20.3%、24.2%和91.2%。
: The contents of genistein and its β-glucoside form, genistin, in 13 soybean varieties were determined. Soybean variety (Var-1) with high genistein and genistin contents (0.019 mg/g and 0.420 mg/g) was used to evaluate the 3 basic soy protein concentrate (SPC) production methods (acid, alcohol, and hot-water leach) for genistin and genistein retention on a total weight basis. The acid leach method gave the highest total genistin + genistein content (0.742 mg/g) compared to SPCs prepared with the hot-water leach method (0.671 mg/g), and the alcohol leach method (0.070 mg/g). The acid leach, hot-water leach and alcohol leach methods had 20.3%, 24.2%, and 91.2% losses of total genistin + genistein, respectively.
