[Objective] The research aimed to study the germ and endosperm of corn by Fourier transform infrared spectrooscopy( FTIR) to provide scientific way for identifying germ and endosperm from different types. [Method]The infrared spectra combined with hierarchical cluster of germ and endosperm from three different types were analyzed. [Result] The results show that the original characteristic infrared spectra of samples are very similar,main absorption peak were composed by polysaccharides,proteins,and lipids. ...
