The structural transition of silk protein has been induced by various method including alcohol treatment. To know the effect of alcohol concentration on silk beads conformation, silk beads were prepared in different alcohol concentration (100%, 70%, and 50%) and then examined the infrared spectra of silk beads. Silk beads prepared in 100% alcohol showed at $1265cm^{-1}$ attributed ${\beta}-sheet$ conformation and did not showed a characteristic absorption peak from model drug. However, silk beads in 70% and 50% alcohol showed some peaks originated from model drug including $2933cm^{-1}$, $1069cm^{-1}$, and $973cm^{-1}$. These results means that the micro-environment of silk beads was affected by alcohol concentration.
