The property of interplanetary dust (IPD), which has been recently emitted from planetesimals like asteroids and/or comets, can give us the information about the environment where asteroids and comets were formed during the planet-formation stage. These can include clues of any planetesimal scattering due to planets' migration. We use silicate features around 10 micrometers as a tracer of the thermal history. In this study, we analyze mid-infrared spectroscopic data of zodiacal emission at 74 different directions obtained with AKARI/IRC. After we examined and subtracted instrumental artifacts, we successfully obtained the high S/N spectra and detected the silicate feature in all pointing data. They also suggest the variations in dust temperature and shape of the feature among different ecliptic latitudes.
