Conversion of sesaminol triglucoside in defatted sesame seed into sesaminol using the fungal metabolism by Absidia corymbifera

A fungus was grown in the wetted defatted sesame seed at room temperature. In the visual observation the colony of the fungus was white and wooly, and in the microscopic observation, its sporangiophore was colorless and branc hed. Based on these observations, we identified the fungus as Absidia corym bifera. The amount of sesaminol triglucoside included in the defatted sesam e seed decreased largely by the incubation of this fungus for 84 h and then , sesaminol that has antioxidative activity was produced largely. Amounts o f sesamin and sesamolin included in the defatted sesame seed did not change by the incubation for 24 h. As the results, we could clarify sesaminol tri glucoside was converted into sesaminol using the fungal metabolism by Absid ia corymbifera.
