Abstract

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
