　　Previous studies have found that tea polyphenols(TPs)could effectivelyinactivateinhibitory activity ofsoybean trypsin inhibitor(STI),but the exact mechanismis unknown.In the present study,the interaction betweensoybean Kunitz trypsin inhibitor(KTI)and(-)-epigallocatechingallate(EGCG)was investigated by spectroscopic analysis(UV-Visspectrum,fluorescence quenching,circular dichroism(CD)and fourier transform infrared(FTIR))as well as thermodynamicsmethod(isothermal titration calorimetry,ITC).
