复合有机酸催化大豆异黄酮糖苷水解成苷元的工艺研究

摘要

通过单因素实验和正交实验，以水解率为评价指标，研究复合有机酸催化大豆异黄酮糖苷水解成苷元的工艺参数。结果表明，最佳水解工艺为：反应温度135℃，反应时间为160 min，复合酸配比（苹果酸∶柠檬酸）为4∶3，水解率达到97．0％以上。复合有机酸催化水解工艺绿色环保，水解产物无需分离，可直接作为保健食品原料，具有较高的应用价值。%The parameters of hydrolysis of soybean isoflavone glycosides catalyzed with complex organic acid were researched by single - factor experiment and orthogonal experiment with hydrolysis rate as the evaluation index. The results showed that the optimal hydrolysis parameters was reaction temperature 135 ℃,reaction time 160 min,ratio of composite acid (malic acid∶ citric acid)4∶ 3,hydrolysis rate can reach to above 97. 0% . The hydrolysates can be used in health food as raw material without been separa-ted. The hydrolysis process is green environmental protection with application value.
