摘要:

研究腐乳前发酵和盐制过程中大豆异黄酮组成和含量的变化。研究结果表明:在腐乳前发酵和盐制过程中,大豆异黄酮的总含量逐渐减少;大豆异黄酮总含量的损失主要是由白坯的制作和盐制过程引起的。在腐乳前发酵和盐制过程中,大豆异黄酮组分也发生改变:随着大豆异黄酮糖苷(daidzin 和genistin)含量的减少,其相应的苷元(daidzein 和genistein)明显增加。盐制过程中较低盐含量下的大豆异黄酮的含量较高。

Abstract:

In this study, change of isoflavone contents and compositions in sufu (fermented tofu) during pre-fermentation and salting was investigated. Results indicated that total content of isoflavones exhibited a gradual decrease during pre-fermentation and salting. The loss of isoflavones was mainly attributed to tofu preparation and salting process. The compositions of isoflavone were altered during pre-fermentation and salting, which revealed an increase of aglycones such as daidzein and genistein, and a corresponding decrease of glucosides such as daidzin and genistin. Total content of isoflavones in sufu treated with less than 10% salt was higher than that of sufu treated with 15% salt.

Key words: sufu, isoflavone, pre-fermentation, NaCl
