摘要:

研究腐乳后酵过程中大豆异黄酮组成和含量的变化。结果表明:在腐乳后酵过程中,大豆异黄酮总含量呈下降趋势;当食盐含量较低时,糖苷(daidzin 和genistin)分解较快;大豆异黄酮糖苷形式(daidzin 和genistin)转化为苷元形式(daidzein 和genistein)。说明腐乳后酵有效提高了大豆异黄酮的生物活性。

Abstract:

In this study, the changes in type and amount of isoflavone in sufu (fermented bean curd) during post-fermentation process were measured. The results indicated that the total content of isoflavones in sufu exhibited a gradual decrease during post-fermentation process. A rapid degradation of isoflavone glucosides such as daidzin and genistin was observed under low salt conditions, which were completely transformed into isoflavone aglycones including daidzein and genistein during post-fermentation process. Therefore, post-fermentation might be beneficial to enhance the physiological function of sufu.

Key words: sufu, isoflavone, post-fermentation process, NaCl
