摘要
对中国几种有代表性的大豆制品进行了异黄酮含量测定。测定结果表明 :中国的大豆制品中含有一定量的异黄酮 ,其中非发酵制品中的异黄酮只有极少量以游离形式存在 ,大部分以 β 葡萄糖苷的形式存在 ,主要是黄豆苷 (daidzin)和染料木素 (genistin) ;而在发酵大豆制品中 ,由于酶的作用 ,部分黄豆苷和染料木素转化成黄豆苷原 (daidzein)和染料木因 (genis tein) ,因此 ,游离态的异黄酮比例增加。中国大豆制品中异黄酮含量随大豆品种和加工工艺而异 ,含量范围在 1 1 2 82～ 1 871 6 1 μg/ g ,这个结果表明中国的大豆制品对人体的健康具有重要作用。
Isoflavones in several typical Chinese soy products have been determined The results obtained indicated: Chinese soy products contain certain amount of isoflavones Among of them, isoflavones in non fermented soy products exist mainly as β glycosides that mainly are daidzin and genistin, but only a small amount of free forms exits; in fermented soy products, due to enzyme's function, part of daidzin and genistin converted into daidzein and genistein, therefore the proportion of free form of isoflavones increased; isoflavones contained in Chinese soy products varies greatly with the soy variety and process technology The range of content is between 112 82 and 1871 61?μg/g based on dry weight This result indicated that Chinese soy products play an important part in people's health
