摘要
对黑豆发芽条件及其中异黄酮提取物特性进行了探讨。结果表明:黑豆最佳发芽条件为浸泡温度38℃、浸泡时间15h、发芽温度32℃、发芽时间50h;发芽黑豆中的异黄酮具有较高的清除羟自由基能力、清除超氧阴离子自由基能力和很好的抗油脂氧化能力;通过对异黄酮组分的测定可知,发芽后以葡糖苷(IFG)形式存在的异黄酮含量降低,以甙元(IFA)形式存在的异黄酮含量增加。
In this study, the experimental results showed that under the conditions of black bean being soaked at 38 ℃ for 15 h and germinating at 32 ℃ for 50 h, the isoflavones content in black bean reaches maximum; The isoflavones extracted form the germinated black bean possess hydroxyl radical and superoxide radical scavenging activities and inhibitory effect on lipid peroxidation; The isoflavone aglycones (IFA) content in germinated black bean is higher than that in native one, but the isoflavone glycosides (IFG) content is lower.
