黑曲霉发酵法制备大豆异黄酮苷元工艺初探

Study on production soybean isoflavone aglycon through aspergillus niger fermentation

利用能产生β-葡萄糖苷酶的黑曲霉作为菌种,对大豆胚芽进行固态发酵,制备大豆异黄酮苷元。考察了几个主要因素对发酵过程中大豆异黄酮苷元产生量的影响,初步探讨了黑曲霉发酵法制备大豆异黄酮苷元的工艺条件。

Aspergillus niger which can secret β-glucosidase was used as the strain for the solid state fermentation to produce soybean isoflavone aglycon from soybean germs. We studied several main factors which can influence the yield of soybean isoflavone aglycon during the fermentation and discussed the parameters of techniques for producing soybean isoflavone aglycon through Aspergillus niger fermentation.
