Both glucose pellets exposed to the irradiation of 10(13), 4 x 10(13), 6 x 10(13), and 8 x 10(13) particles/cm(2) of the particle's fluence, were characterized using complex refractive indices in terahertz frequency region. We found that fingerprints of two types of glucose in terahertz frequency were disappeared above 8 x 10(13) particles/cm(2). Crystallinity breaking and molecular structure change by proton irradiation was reaffirmed using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy.
